Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, Andy. Welcome everybody. It's great to see you all here today. Next slide please.

2024 was a very strong year for our company, I would say a very, very amazing year, I have to say, with total revenue up 21% and a core EPS up 19% as you can see here, a clear illustration of the strong underlying momentum of our company. I've also listed here 14% on core opex to show that we continue to work on leverage with a lower growth of our expenses relative to the growth of our total revenue. We also delivered important pipeline advancements with nine high value pivotal trials readouts in 2024. Combined, these trials represent over $5 billion in non-risk adjusted peak year revenue.

Don’t miss this second chance at a potentially lucrative opportunity

Ever feel like you missed the boat in buying the most successful stocks? Then you’ll want to hear this.

On rare occasions, our expert team of analysts issues a “Double Down” stock recommendation for companies that they think are about to pop. If you’re worried you’ve already missed your chance to invest, now is the best time to buy before it’s too late. And the numbers speak for themselves:

• Nvidia: if you invested $1,000 when we doubled down in 2009, you’d have $323,686!*
• Apple: if you invested $1,000 when we doubled down in 2008, you’d have $44,026!*
• Netflix: if you invested $1,000 when we doubled down in 2004, you’d have $545,283!*

Right now, we’re issuing “Double Down” alerts for three incredible companies, and there may not be another chance like this anytime soon.

We had, of course, more readouts than those nine, but those are the most high value readouts we had last year. At our Investor Day in May, we communicated our ambition to deliver 20 new medicines by 2030 and I'm pleased to report that we have eight new medicines approved to date, including the recent approval of Datroway, which was previously called Dato-DXD earlier this year. So if you move to the next slide, we continue to benefit from our broad based diverse portfolio of products and diverse geography and we have strong growth across all our therapy areas as you can see here and our key geographies in 2024. In the year ahead, we anticipate sustained demand for our innovative medicines and growth across geographies.

In our results announcement, we provided an update on ongoing investigations in China. We've received a notification from the Shenzhen City Customs Office regarding suspected unpaid importation taxes totaling $900,000, which to the best of our knowledge relates to Imfinzi and Imjudo. So if actually AstraZeneca was found liable, a fine of between one to five times the amount of avoided import duties could have to be paid by AstraZeneca. We are continuing to cooperate with the government toward resolution of those investigations.

I'm pleased to have Iskra, we call her Super Iskra, joining us today in her new role as Head of International. I would now like to invite Iskra to share early perspectives on her new jobs and in particular China. Over to you Iskra.

Iskra Reic -- Executive Vice President, International

Thank you, Pascal. No pressure with the nickname. I'm very honored to have assumed responsibilities in the international region that as you all know combines China, emerging markets as well as Australia and New Zealand. Initially, when I started in my new role, my focus was really in how best to support our colleagues in China at the unsettling time for them.

And I have been really truly impressed by their continued effort and passion to deliver on the values and our purpose and I have a real strong confidence in the leadership that we have in place in China. China revenues last year had increased by 15% throughout the first nine months and overall 2024 growth is 11% because of the quarter four decline of 3%. It is very important to note that that decline was primarily driven by year-end hospital ordering dynamic which affected a few products, specifically Tagrisso and Farxiga as well as demand for our respiratory products that is lower given the mild start of the winter. And while we do expect some headwinds specifically driven by VVP inclusion for our several medicines, we do expect the growth in China will continue and especially in the longer term where we see a strong opportunity and we are fully committed to continue growing in China.

If I think about the emerging markets more broadly, I think you all know that we have been building our presence and capabilities for many years, accelerating our regulatory approvals and also doing our best to broaden our equitable access and we have seen strong growth over the past several years and we do expect that growth to continue. In 2024, overall emerging market growth was at 22%. The unmet need across the emerging markets is unprecedented or enormous. I mean if you look at any therapy area, but specifically if you look at the areas where we work, just to give you one example, in emerging markets, it's estimated that 1.8 million people will be diagnosed with lung cancer that represents actually 70% of the overall lung cancer diagnosis over the -- in the globe.

The substantial unmet need, coupled with the increased investment in the healthcare as well as increased willingness to pay for the healthcare, gives us an opportunity to deliver and sustain and significant growth going forward. Thank you. Please advance to the next slide and I will give floor back to Pascal.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, Iskra. So as you heard from Iskra, there is enormous opportunities in the emerging markets, not only in China, but also outside of China and Iskra knows the region very well. So we'll definitely have a big impact on our future growth and we look forward to resolving the issues that we've been facing in China, of course. 2025 marks the beginning of an unprecedented catalyst rich period for our company.

We have talked about it before. We're looking forward to the results of high-value trial readouts this year for several of our existing medicines including in HER2, Datroway, Imfinzi, Breztri and Fasenra. And importantly, we also anticipate the first phase 3 data for seven enemies, seven including camizestrant and baxdrostat, two medicines which each have a potential to generate more than $5 billion in peak revenue. The value of our pipeline has been increasing steadily and, as I had not communicated earlier this year, we now have more than 90 late-stage trials underway with an average non-risk adjusted peak year revenue per trial of $1 billion.

Looking only at the anticipated readouts in 2025 shown here, taken together this represents over $15 billion in non-risk adjusted peak year revenue potential. And that's why we have said a few times, by the end of this year, early 2026, everybody will have a good sense as to our chances to get to the $80 billion. You'll see the momentum that we have in our company plus you will see the outcomes of those trials. With that, please advance to the next slide and we'll hand over to Aradhana, who will take you through our financials.

Aradhana Sarin -- Executive Director and Chief Financial Officer

Thank you, Pascal, and good morning everyone. As usual, I will start with our reported P&L. Next slide, please. As Pascal highlighted, our company delivered very strong performance in 2024.

Total revenue grew by 25% in the fourth quarter with full-year revenues up 21% exceeding our twice updated guidance range of high teens percentage increase. Product sales grew by 19% in the full year driven by strong underlying demand for our medicines across regions. Alliance revenue increased by 55% reflecting growing demand for HER2 and Tezspire in regions where our partners book product sales. Collaboration revenue increased by 54% driven primarily by a $600 million Lynparza sales milestone recognized in the fourth quarter as well as smaller sales milestones for Beyfortus and Koselugo.

Next slide, please. This is our core P&L. Our core product sales gross margin in 2024 was 81.2% in line with our indication for a slight decrease compared to full-year 2023. Core operating expense increased by 14% in 2024, well below the top-line growth of 21%.

Core R&D expense increased by 19% and consistent with our prior commentary, as a percentage of total revenue, core R&D expense was toward the upper end of the low 20s percentage range. This increase supported multiple new trial starts, including phase 2 trial starts for our weight management portfolio and the acceleration of our cell therapy programs. It also reflects costs following the closure of several business development transactions in 2024. Core SG&A costs increased by 11% reflecting continued investments behind launching brands.

SG&A decreased to 28% of total revenue on a full-year basis. Other operating income declined significantly as we booked more than $700 million in 2023 relating to the update of the contractual agreement on Beyfortus, as well as $250 million relating to the U.S. divestment of Pulmicort. Core EPS of $8.21 represents 19% growth placing us at the top end of our full-year guidance.

Next slide, please. Our net cash flow from operating activities increased by $1.5 billion in 2024. capex of $2.2 billion was broadly in line with the indication of a 50% projected increase over 2023. This includes both tangible and software related intangible assets.

We completed a number of business development transactions in 2024 including the acquisition of Amolyt, Icosavax and Fusion and incurred total debt payments close to $7 billion. We anticipate deal payments relating to past transactions of approximately $3 billion in 2025. Net debt increased by $2.1 billion to $24.6 billion, which is a level we are comfortable with. Given the growth in our EBITDA, our current net debt-to-EBITDA ratio stands at 1.5 times.

We increased the full-year 2024 dividend to $3.10 per share and announced this morning that we intend to increase our full-year 2025 dividend to $3.20. Today, we issued guidance for 2025 and expect total revenue to increase by a high single-digit percentage and core EPS to increase by low double-digit percentage. We anticipate our strong growth momentum to continue in 2025, more than offsetting the headwinds that we have previously indicated. These dynamics also adversely impact our product sales growth margin, and we anticipate an incremental 70 basis points decline driven by the net effect of the IRA in the U.S., the anticipated inclusion in VBP of Farxiga, Lynparza in China, as well as the growth of our partnered products that have lower gross margins.

Operating leverage remains a priority for our company. We continue to anticipate SG&A costs to grow at a slower pace than revenue. We are beginning to see benefits from the redeployment of our global footprint and continue to optimize our commercial investments across key disease areas to support new launches. R&D expenses are expected to remain in the low 20s percentage range of total revenue.

Our full year guidance is, as usual, at constant exchange rates. Based on average January 2025 rates, we anticipate a low single-digit adverse FX impact on total revenue and a mid-single-digit adverse impact on core EPS. The recent strengthening of the U.S. dollar also affect our core operating margin percentage, and we estimate an adverse impact of roughly 20 basis points in 2025 based on average January 2025 FX rates compared to average rates for full year 2024 and roughly 50 basis points as compared to average FX rates in first quarter 2024.

Please turn to the next slide. In 2025, we expect expenditure on tangible and software-related intangible assets to increase by approximately 50%, driven by manufacturing expansion projects and investments in systems and technology, that will support our long-term growth ambitions. Today, we have a diverse and resilient supply chain with 26 production facilities in 15 countries that affords us optionality and agility, while addressing global demand for our medicines. The increased manufacturing investments we are making include investments into next-generation capabilities for both small molecules and large molecules, as well as transformative technologies such as ADCs, cell therapies and oligonucleotides globally.

Already in progress are a new end-to-end ADC manufacturing site in Singapore, a cell therapy manufacturing site in Rockville, Maryland and an API facility in Dublin, Ireland and a site in Qingdao, China for inhaled therapies. In November last year, we also announced several investments in the U.S., including a specialty manufacturing facility in Texas. All of these are multiyear projects that illustrate how we are supporting our growing pipeline, including drivers of growth post 2030. Lastly, we are upgrading our data and ERP systems to set the data foundation to support our growth and enable us to more fully leverage innovation in AI and make our business more efficient.

With that, please turn to the next slide, and I will hand over to Dave, who will take you through the oncology performance.

David Fredrickson -- Executive Vice President, Oncology Business

Thank you very much, Aradhana. Next slide, please. So in 2024, Oncology delivered total revenues of $22.4 billion, which was an impressive increase of 24% with key medicines surpassing new multi-blockbuster milestones with Tagrisso achieving over $6.5 billion; Lynparza over $3 billion in product sales; Imfinzi and Imjudo combined approaching $5 billion; Calquence and Enhertu achieving over in $2 billion in full-year revenues, respectively. This strong growth really does signal clear progress on our mission to deliver medicines with potential to transform outcomes for patients globally.

Turning now to fourth quarter performance for our key medicines, Tagrisso global revenues grew 21% reflecting strong growth across all indications, partly offset by the customary fourth quarter hospital ordering dynamics that you heard about earlier in China. In the frontline setting, Tagrisso achieved over 75% market share globally, with close to 85% market share in the U.S. We continue to make steady gains in the adjuvant setting with ADAURA and saw encouraging early launch uptake for LAURA in early stage unresectable lung cancer. Calquence total revenues increased 20% in the fourth quarter driven by sustained BTK inhibitor leadership in the frontline CLL setting and contingent expansion in the phase of pretty fierce competition.

In the fourth quarter, Imfinzi and Imjudo delivered 18% and 28% growth, respectively, and continued demand across lung and liver cancer in the U.S., as well as accelerating adoption of TOPAZ and HIMALAYA in Europe. As expected, we saw continued impact on established rest of world revenues following the two mandatory price reductions in Japan that took effect in 2024. Lynparza achieved global sales of over $3 billion in 2024, triggering receipt of a $600 million milestone payment in the fourth quarter, which was recorded in collaboration revenue. As the established standard-of-care across HER2-positive and HER2 low metastatic breast cancer, Enhertu delivered total revenue growth of 54% in the fourth quarter, partly offset by compensation following recent NRDL listings in China for DESTINY-Breast03 and DESTINY-Breast04.

Last week, we received FDA approval and NCCN guideline inclusion for DESTINY-Breast06, which will further drive adoption in the ultralow setting. Truqap delivered $163 million in fourth quarter revenues, which partially benefited from stocking following the launch of the blister packs in the U.S. And I'm pleased to report Truqap is now a market leader in the second line, biomarker-altered, patient population. We received a number of landmark regulatory approvals since third-quarter results, including U.S.

and Japan approvals for Datroway, in HR-positive HER2-negative breast cancer; U.S. approval for Calquence in mantle cell lymphoma; Imfinzi and limited-stage small cell lung cancer; and European approval for Tagrisso in early stage unresectable lung cancer. And finally, we received priority review designations for Datroway and late-line EGFR-positive lung cancer based on the TROPION-Lung05 study; and Imfinzi and muscle invasive bladder cancer, signaling the potential value of our rapidly advancing oncology pipeline. Next slide please.

So coming off this remarkable year of growth, we see continued momentum for our oncology medicines in 2025, particularly Tagrisso, Enhertu, and Imfinzi despite the incremental impact from Part D redesign and the anticipated inclusion of Lynparza in VBP Batch 11 in China. Tagrisso is positioned to remain the market leader in frontline EGFR-mutated, non-small cell lung cancer, and we expect continued expansion of ADAURA and LAURA in early stage disease in the year ahead. Longer-term combination trials are designed to reinforce Tagrisso as the backbone TKI, addressing late-line MET-driven disease resistance with SAFFRON and SAVANNAH, and investigating novel ADC combinations with TROPION-Lung14 and 15. For Enhertu, we anticipate new international launches for HER2-positive and HER2 low breast cancer, as well as further expansion from DESTINY-Breast06 to drive growth over the course of this year.

Moreover, the HER2-positive breast cancer trials reading out this year represent the next meaningful leg of growth for Enhertu. On Imfinzi, following positive phase 3 readouts in lung and bladder last year, we anticipated ADRIATIC, AEGEAN, and NIAGARA launches to initiate the next wave of Imfinzi growth, bolstered by continued adoption of HIMALAYA in liver cancer. And beyond 2025, we expect bladder and GI to unlock further expansion for Imfinzi and Imjudo. We expect Calquence to remain the leading BTK inhibitor in frontline CLL supported by accelerating volume over the balance of the year.

However, we do anticipate gross to net pressure both from Part D redesign and where we've taken contracting decisions to secure preferred formulary access in the United States. We expect meaningful demand growth upon the approval of AMPLIFY, which will allow us to grow finite therapy segment, which represents nearly half of the CLL frontline market today. And finally, for Truqap, our most recent launched medicine, we see continued market leadership in the core, second-line biomarker altered population. We're set to deliver another year of strong growth, which is supported by continued growth of medicines, as well as meaningful indication expansion opportunities.

And with that, please advance to the next slide, and I will hand it over to Susan to cover R&D.

Susan Galbraith -- Executive Vice President, Oncology Research and Development

Thank you, Dave. So 2025 is shaping up to be a very exciting year across our Oncology pipeline. We look to maximize the reach of our innovative medicines across lung, breast, GI and bladder cancers and present additional data for some of our transformative technologies, including our I/O bispecifics, ADCs, and T-cell engagers. In the second half of 2025, we plan to announce the high-level results from the phase 3 AVANZAR study of Datroway in combination with Imfinzi and platinum chemotherapy in patients with first-line non-small cell lung cancer.

AVANZAR will be the first of five phase 3 trials in frontline non-small cell lung cancer to read out and has potential to not only confirm combination efficacy with I-O but also serve as the first prospective validation of the TROP2 QCS NMR biomarker. Importantly, we recently amended the primary endpoint to focus on the non-squamous population and to look at the benefit in both TROP2-positive non-squamous and the broader non-squamous population, which we believe increases the probability of the trial's success. Additionally, we expect results from the TROP2-Breast02 trial of Datroway in triple-negative breast cancer in the first half of this year. In 2025, Enhertu will move into earlier lines of treatment of HER2-positive breast cancer.

DESTINY-Breast09 aims to bring Enhertu to the first-line metastatic setting with both monotherapy and pertuzumab combination options. DESTINY-Breast05 and 11 are the first two readouts for Enhertu in the early breast cancer setting, where the opportunity for cure is even higher. Our Imfinzi bladder and gastric programs continue to advance with readouts for VOLGA, which builds on NIAGARA, the combination of enfortumab vedotin and Imfinzi plus minus Imjudo in patients with muscle-invasive bladder cancer with POTOMAC in non-muscle invasive bladder cancer and with MATTERHORN in gastric cancer. Together, these trials represent meaningful new opportunities for Datroway, Enhertu, and Imfinzi as we look to expand the reach of these transformative medicines.

This year, we'll also report phase 3 results from a very promising NME in our pipeline, camizestrant, which has potential to be the best-in-class next-generation oral SERD. As a complete estrogen receptor antagonist, camizestrant not only binds the receptor, inhibiting transcriptional activity, but it also induces degradation of the receptor itself. In contrast, aromatase inhibitors only reduce production of the ligand estrogen, reducing ligand driven transcription activity but leaving the estrogen receptor in place. This dual action of camizestrant gives us confidence that it can provide greater benefit to patients than aromatase inhibitors regardless of ESR1 mutation status.

Our confidence is supported by the data from the phase 2 SERENA-2 trial, where we saw a similar median progression-free survival of six to eight months with camizestrant regardless of the ESR1 status and a benefit over fulvestrant in head-to-head data with a hazard ratio of 0.58 in the ITT population and 0.33 in the ESR1 mutant population. These data, taken together with the low discontinuation rates, low rates of GI toxicities which can be bothersome to patients and the ability to combine camizestrant with all three major CDK4/6 inhibitors, these together drive our confidence across the SERENA and CAMBRIA studies. SERENA-6 is the first phase 3 trial to readout and investigate switching the endocrine partner of any CDK4/6 inhibitor from an aromatase inhibitor to camizestrant on emergence of an ESR1 mutation during first-line treatment. The goal of SERENA-6 is to extend the duration of benefit in first line.

ESR1 mutations are treatment acquired with low prevalence at the time of metastatic diagnosis around 5%, increasing to around 40% of the time of disease progression at the end of first-line treatment. SERENA-6 addresses the pool of patients currently on first-line aromatase inhibitor plus CDK4/6 inhibitor treatment who have these emerging ESR1 mutations without disease progression on clinical scan. And we estimate this to be around 30% of all endocrine-sensitive first-line patients. While SERENA-6 focuses on these first-line patients that have emergence of ESR1 mutations, SERENA-4 targets a broader first-line population, those patients with newly diagnosed hormone receptor-positive endocrine-sensitive metastatic breast cancer, and investigate upfront combination of camizestrant and palbociclib.

Similarly, we have two ongoing adjuvant trials, CAMBRIA-1, which looks as a switch strategy to extend treatment after two to five years of endocrine therapy with or without a CDK4/6 inhibitor. And CAMBRIA-2, which investigates the upfront combination of camizestrant with or without palbociclib. We look forward to updating you on our camizestrant clinical program, which is designed to support our ambition to establish this new endocrine therapy as a backbone in hormone receptor-positive HER2-negative breast cancer. Finally, we continue to progress our transformative technologies into phase 3.

We now have nine ongoing phase 3s for our I-O bispecifics and plan to share early data for combinations of rilvegostomig with Datroway and Enhertu later this year. Last year, we progressed AZD0901, our CLDN18.2 ADC into phase 3. And this year, we plan to advance our B7-H4 targeted ADC with our proprietary linker topo 1 payload, puxitatug samrotecan, otherwise known as P-Sam, if you find puxitatug difficult to pronounce, into a phase 3 trial in endometrial cancer. In addition, we recently initiated the SOUNDTRACK-F1 trial, our first phase 3 trial for the CD19/CD3 T cell engager, ASD-0486, in follicular lymphoma.

These transformative technologies help support delivery of sustained growth beyond 2030. And with that, please advance to the next slide, and I'll pass over to Ruud to cover BioPharmaceuticals performance.

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Thank you so much, Susan. Our BioPharmaceuticals medicine saw another very strong year of performance in 2024 with total revenue growing 21% to $21.9 billion. In the fourth quarter, BioPharmaceuticals growth was 24%. R&I grew by 28%, an impressive performance despite softer demand in China due to a mild start to the winter season for respiratory viruses.

CVRM grew 17% with strong Farxiga growth of 22%, which was partly offset by year-end hospital budget dynamics in China. Alongside Fasenra and Symbicort, Tezspire became the third blockbuster medicine in our respiratory portfolio with over $1 billion in combined global end market sales. Soon, we can expect to see a fourth blockbuster on that list as Breztri delivered over $0.25 billion in revenue in the fourth quarter. Given strong global demand and increased production capacity for Beyfortus, we recorded a sales-related milestone payment of $111 million in the fourth quarter.

The launch of Wainua in ATTR polyneuropathy is progressing very well. And we are excited about the longer-term opportunity in the broader ATTR cardiomyopathy indication. And following the commercial launch of Airsupra early last year, we have seen impressive volume growth, and we continue to work on broadening the access for patients. Next slide, please.

We look forward to another year of strong performance in 2025 despite the anticipated Brilinta loss of exclusivity and the potential VBP inclusion for Farxiga and Roxadustat. Outside of China, we expect to see further growth for Farxiga due to the continued market leadership in the fast-growing SGLT2 class and see potential for increased adoption with millions of patients still not receiving guideline-directed therapy. Lokelma surpassed $0.5 billion in total revenue last year, and there's a growing body of evidence showing that Lokelma can help CKD and heart failure patients with hyperkalemia while maintaining guideline-directed therapy. We expect continued growth with further adoption and longer duration of treatment due to demonstrated real-world clinical benefits.

Breztri has grown rapidly in the last two years and has gained over two-thirds of the market in China as COPD is a leading cause of death. We anticipate continued growth in China, following the recent addition of COPD to the country's national public health program. Our biological respiratory medicines have a strong competitive position in the growing market. Biological penetration in asthma remains relatively low with potential for sustained long-term growth.

And the COPD biological market is still immature. In 2025, we anticipate continued growth from our biologic portfolio in asthma, and we're looking forward to the upcoming RESOLUTE phase 3 readout for Fasenra in COPD. Finally, Saphnelo has steadily gained share among systemic lupus erythematosus patients treated with intravenous infusions and remains the leading IV biologic in several markets. Subcutaneous biologics represent more than half of the market for SLE today.

The ongoing TULIP-SC trial is studying a subcutaneous formulation of Saphnelo and has the potential to open a new market opportunity. Our BioPharmaceuticals portfolio is poised for continued growth in 2025, and I will now hand over to Sharon to discuss the latest developments from the BioPharmaceuticals pipeline. Next slide, please.

Sharon Barr -- Executive Vice President, BioPharmaceuticals Research and Development

Thanks, Ruud. So 2024 was an exciting year in BioPharma. And in 2025, the momentum continues as we rapidly advance both indication expansion and NME pipeline opportunities. In respiratory and immunology, we are building an industry-leading portfolio in asthma and COPD with the opportunity to expand our presence in these diseases, where high unmet medical need remains, with key indication expansion opportunities this year as well as NMEs in late-stage development.

Starting with Breztri, our triple combination inhaler, already approved in COPD. We have the opportunity to improve care for people suffering from uncontrolled asthma with a new treatment option. In the phase 3 KALOS and LOGOS trials, Breztri has the potential to demonstrate asthma control by improved lung function versus current dual combination ICS/LABA treatment, and we look forward to these data readouts in the first half of this year. Fasenra, our IL-5 monoclonal antibody represents another meaningful opportunity to expand our reach beyond severe eosinophilic asthma and EGPA into COPD with the phase 3 RESOLUTE trial.

Characterized by airway blockage and long-term respiratory symptoms, COPD remains the third leading cause of death globally. Many patients are not well managed and remain at risk of exacerbations that increase the risk of hospitalization and mortality. With our strong foundation in biologics, we are seeking to address a broad spectrum of this highly complex and heterogeneous disease through differentiated mechanisms of action to address the underlying inflammatory pathways that may trigger COPD. As a key contributor to inflammation, eosinophils are potent effector cells that are believed to play a role in COPD.

The phase 3 RESOLUTE trial for Fasenra addresses a population with eosinophilic COPD with baseline blood eosinophils of 300 or above, which represents about 30% of the market. To further broaden our reach in COPD, we look forward to initiating a phase 3 Tezspire trial later this year in patients with eosinophils greater than 150. And lastly, with our IL-33 monoclonal antibody, tozorakimab, we look forward to the results from our phase 3 LUNA program next year, which is targeting a COPD population irrespective of eosinophil levels and smoking status. Tozorakimab received FDA Fast Track Designation at the end of 2024, emphasizing the high unmet medical need for this disease.

With a robust pipeline of differentiated mechanisms, we have an opportunity to transform outcomes in COPD. Now turning your focus to the right-hand side of the slide. In CVRM, we eagerly await the first phase 3 data from baxdrostat, our novel aldosterone synthase inhibitor. Both the monotherapy and in combination with dapagliflozin, baxdrostat represents a multi-blockbuster opportunity across areas where patients urgently need new options.

In the second half of this year, we will see data from the phase 3 BaxHTN trial, assessing baxdrostat as a monotherapy in uncontrolled or resistant hypertension. We have already seen encouraging blood pressure reduction in phase 2. The PK profile supports 24-hour systolic blood pressure control, which we are looking to confirm in the Bax24 trial also reading out in the second half of 2025. The phase 3 combination trial of baxdrostat with dapagliflozin BaxDuoArctic for those living with kidney disease and high blood pressure was also initiated this past year.

This reinforces our unique ability for multi-mechanism combinations to address interrelated diseases across our CVRM portfolio. Lastly, as we continue to build the next wave of transformative medicines in CVRM, I am excited to share that we have recently completed the phase 2b PURSUIT trial for AZD0780, our oral PCSK9 inhibitor, and we look forward to sharing the data at the American College of Cardiology Annual Meeting next month. With that, please move to the next slide, and I will hand over to Marc to cover our rare to fees portfolio.

Marc Pierre Jean Dunoyer -- Chief Executive Officer, Alexion and Chief Strategy Officer, AstraZeneca

Thank you, Sharon, and next slide, please. The rare disease delivered total revenue of $8.8 billion in 2024, up 16% year over year driven by an increased patient demand and launches in new markets. Total revenue growth included a 2% benefit from a sales milestone for Koselugo received in the fourth quarter. In the quarter, Ultomiris grew 33% driven by neurology indications, with the vast majority of growth coming from generalized myasthenia gravis patients who are naïve to branded treatments.

Outside of emerging market, Soliris revenue continued to decline due to the successful conversion to Ultomiris, some competition, and in Europe, biosimilar pressure. As a reminder, we expect biosimilars to enter the U.S. market in March of this year. Beyond the complement, Strensiq and Koselugo grew 37% and 97%, respectively, driven by continued patient demand, new launches, and a favorable tender or the timing in emerging markets.

2024 was another year of double-digit growth for rare disease medicine, and we see momentum continuing in 2025. Can I advance to the next slide? Ultomiris continue to grow, driven primarily by neurology indications, including patients who are new to branded medicine and Soliris switch patients as well as further market expansion. We indicated peak year sales for Ultomiris to be above $5 billion with contribution from both existing and new indication opportunities, including HSCT-TMA, CSA-AKI, and IgAN. For Strensiq, we anticipate further adoption supported by new hypophosphatasia guidelines, which have led to an increased disease awareness, diagnosis rate,s and accelerated new patient starts.

As we continue to launch Strensiq in new markets globally, we are focused on disease education, which prepare markets ahead of the next-generation efzimfotase alfa launch. Patient demand and geographic expansion continue to drive Koselugo growth in pediatric patients with NF1-PN. And following the positive phase 3 trial results in adult with NF1-PN, we expect KOMET to drive growth beyond 2025. We are well placed to deliver another year of strong growth, supporting by global demand for rare disease medicine as well as meaningful indication expansion opportunities.

Please advance to the next slide. We anticipate 2025 to be a catalyst-rich year, unlocking the next wave of rare disease medicine. We expect five phase 3 readouts across multiple indications, four of which four new molecular entities. Following phase 2 data, we believe eneboparatide, PTH receptor agonist has the potential to normalize serum calcium levels, decrease urinary calcium and preserve bone mineral density, all clinical priorities of hypoparathyroidism.

Novel deplete anselamimab has been developed to remove toxic like in amyloid fibrils that accumulate in the heart and kidneys. In light chain amyloidosis this fibril is co-systemic and progressive organ damage, hospitalization, and high mortality when accumulated. Efzimfotase alfa, our next-gen enzyme replacement therapy is being studied in a board hypophosphatasia population. With an improved profile which allows for lower dosing and lower frequency, it has the potential to address 6 times the patient population versus Strensiq.

Third-generation C5 inhibitor, gefurulimab, VHH that allows for weekly subcutaneous administration has the potential to expand our reach in myasthenia gravis to treat an earlier and broader population. And lastly in for Ultomiris in HSCT-TMA, the product has the potential to address life-threatening complication of stem cell transplant and represent the first indication expansion opportunity for Ultomiris beyond the Soliris label. These trials combined represented significant peak year revenue potential, marking a meaningful contribution to the rare disease portfolio. And with this, I will hand over to Pascal.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, Marc, and I will try to conclude quickly, so we can move to the Q&A session. Next slide, please. So as you can see here, we are making a very important step toward the achievement of our strategic ambitions, in particular, the $80 billion sales in 2030. And we are progressing high-value readouts that will unlock further growth.

So if we move to the next slide, this is an important slide because it really shows that the investments we are making. And of course, those investments create R&D budget expansion, but those are investments that are not only supporting the growth of our existing and late-stage portfolio, but we're also building capabilities and capacity with potentially transformative technologies shown here, our goals is to be a growth company until 2030 but also beyond 2030 and anticipate today what will shape the future of medicine and how we will actually continue to grow despite patent expiries that may happen post 2030. And with this, I'm really pleased to report that we're making very good progress in all of these areas with multiple pivotal trials planned or initiated for our ADCs, our bispecifics, and most recently, our CAR-T NRT cell engager programs. This transformative technologies have the potential to drive sustained growth beyond 2030.

Next slide, please. We continue to make progress, against all the ambitions outlined at our Investor Day in May 2024. We set our sights on $80 billion in total revenue by 2030, as we communicated at the Investor Day. By the end of this year, early 2026 latest, we'll have a very good idea as to whether this ambition can be achieved.

We're working hard to drive operating leverage throughout our company, and we continue to make good progress toward achieving our ambition for mid-30s operating margin in 2026. And finally, and most importantly, we have actually delivered eight new medicines toward our goal of 20 by 2030, and that demonstrate our ability as a team to deliver life-changing medicines for patients globally. Please move to the next slide. [Operator instructions] And with that let's move to the first question.

Thank you. Let's start with this table and we go around the table and move to the next table. Yes, James, maybe you can start.

James Gordon -- Analyst

Thanks for taking the question. James Gordon from J.P. Morgan. I'll stick to one theme which will be China.

So a couple of questions on China. So one would be -- so revenue is down 3% in Q4. But how did it evolve during the quarter? So what did it look like before there was the investigation on November 5 versus afterwards? And more recently, like the start of this year, are things getting better or worse in China? Also in China, so the 2025, so you've given us a group guide, but what does that assume for China? And I can see we've got Lynparza and probably Farxiga VBP. So should we assume that China is going to decline overall, not just because of the investigation but also but VBP but EM overall still grows, how to think about that.

And then just finally, on China. So I think there've been investigations going for some time but I've not seen any provision for a fine or other penalty in your disclosures. So how should we read that? Does that -- you don't think there is likelihood that you're going to have to pay something material? Or is it just you wouldn't provision for it at this time? When would you have to have a provision for something?

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, James. So let me start with the last question, and then for the business development and business growth, I'll ask Iskra to comment and maybe Aradhana to take the guidance question. So we actually disclosed things as we learn about this investigation. And important piece is that, we disclose anything that we believe will have a potential liability dimension.

We disclosed this in our release. I would like to refer you to this and look at it. So if you look at these things in turn, first of all, the illegal importation. We've communicated $0.9 million of avoided import duties.

To the best of our ability -- to the best of our knowledge, as we said, it relates to Imfinzi and Imjudo, the fine that could be associated with that if AstraZeneca is found liable for it would be one to five times the amount of avoided import duties, so five times -- maximum five times the $0.9 million. Now it is possible that Enhertu, for instance, will be affected as well because those products -- the products that are affected essentially products that were approved in Hong Kong, not yet approved on the Mainland. And there's a limited period of time during which patients actually can totally, legally go to Hong Kong and get their medicines. But of course, some people found the opportunity here to take this product from Hong Kong and deliver them to the patients on the Mainland, and that is illegal.

Patients can go, get their medicines. Other people are not allowed to do the transportation, if you want, of those medicines to patients. So we know Enhertu, of course, had a period of time when it was approved in Hong Kong, not on the Mainland. So that could be another one.

But again, the turnover associated with Enhertu is a bit bigger than Imfinzi. But it's not going to be massively bigger. So that's the illegal importation case. And that's basically what we know in terms of the so-called fraud case.

Again, I just like to remind you, we disclose in the litigation section anything that could have liability dimension for the company. Now some of you would like to, I'm sure understand better the sort of individual responsibility, corporate responsibility, legal aspects as it relates to fraud case like this. My best advice is to suggest that you contact one of the magic so-called firms here in London, make sure you -- to get advice, independent advice from them. Make sure you ask a firm that has an affiliate in China, our partner in China that has a license to comment on Chinese laws.

Because global firms are not allowed to comment on Chinese law. So if you want a precise, reliable answer, you have to get it from someone who has a license in China. So ask them and you'll get, I believe, a very clear answer to that question. And that's really the most we can actually talk about this case.

If I go back to your first question, James, the sales in -- at the end of last year in Q4, I mean, when people -- when hospitals manage their inventory, manage their budgets, they start doing this in November, December. So that's what we saw and what typically you see. But the biggest thing is that to keep in mind is that the impact was very much our respiratory products. And into January, we see, I think, a pretty good trend.

But of course, the respiratory products are still affected. Iskra, over to you and then maybe, Aradhana.

Iskra Reic -- Executive Vice President, International

Yes. Thanks, Pascal. So thanks for the question. So I think the -- as Pascal mentioned, I mean, there is not much to read in the dynamic of the quarter four, because it's really -- you will see the same trend in the respiratory products given the mild winter.

And it's interesting to look at because it's -- because of the mild winter, clearly you have a lower level of the flu infection that drives lower rate of the hospitalization. And particularly in China, those products, Pulmicort in particular, are really used the hospitalization and exacerbation. And if you look at the overall inhaled market, you will also see the significant slowdown in growth. Quarter 4, growth of the inhaled market was 9% versus 23% in quarter three.

So I would argue that's a very clear dynamic that you can see throughout the quarter. As you know, the winter is back and the flu infections in China are quite up. So you would you would argue that you may expect the respiratory portfolio performing as expected as normal in the quarter one. I think the second mentioned dynamic was the hospital capping.

And I think it's -- you see the similar trend, I would argue, the same trend as you saw for the top 10 brands in the -- listed in the hospitals in China. The only difference is that this year, that effect was a bit bigger because more hospitals were introducing the hospital capping, trying to manage their budgets and the pressure at the end of the year. But overall, it's looking, in 2025, obviously, early days. But you do expect the portfolio to continue to grow.

We have a few good news in the year we can here to being included in NRDL with the eight other renewals in an NRDL and regulatory approval of the two new indications for Tagrisso and Lynparza. So despite the headwinds that we expect from the VBP inclusion in Farxiga, Lynparza and roxadustat, we do you expect the rest of the portfolio to continue to grow.

Pascal Soriot -- Executive Director and Chief Executive Officer

The biggest headwind really is VBP in 2025. Iskra, maybe you wanted to say a little bit about the team, where they are at. I think it's important to get a sense for potential momentum into 2025 but also our interactions with the medical community in China.

Iskra Reic -- Executive Vice President, International

Yes. I just spent four, five weeks in Shanghai, and I was really impressed on one side, as I mentioned in my remarks, on the commitment and -- of the team. Equally, I was impressed that -- it was unsettling moment in November and December, but I was really impressed how -- with the stability that we introduced in December and the clear focus on what the team needs to do, that both team in the office and on the ground are very much focused and keen to continue doing what we do best, and that is delivering our innovative medicines to the patients in China. And I think the message of the company commitment and our belief that our strategy in China is the right one that we believe in the -- in our ability to deliver for patients, but equally to use a growing innovation in China for China and for global is very much -- landed very well internally as well as externally.

I think, from my external interactions with many different stakeholders there. I think it's also clear that our partners and stakeholders in China willing and happy that we will continue invest and partner with them in order to bring innovations together.

Pascal Soriot -- Executive Director and Chief Executive Officer

Aradhana?

Aradhana Sarin -- Executive Director and Chief Financial Officer

Sure. So on the guidance, obviously, the China is included in our guidance, we do assume growth from our underlying brands as well as the NRDL other inclusions that Iskra talked about. But at the same time, there is headwind from VBP, again, three large products obviously being included in VBP this year, as well as some disruption from some of the ongoing investigation and team stability and so forth.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Aradhana.

Luisa Hector -- Berenberg Capital Markets -- Analyst

Thank you. Luisa Hector from Berenberg. I have just one more on China and then some on the outlook. So for China, can you then confirm if there have been no notable changes in your market share for key drugs in China? And then for the outlook, perhaps just to quantify, if you can, the Part D impact for 2025 redesign.

I think I only heard mention of Calquence from Dave, but perhaps other products to be aware of. And Aradhana, you mentioned $3 billion of deal-related payments. I'm just curious whether you can provide any color on the components. And should we assume that the majority of those come essentially with success, so pipeline success, sales success? Thank you.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, Luisa. I can see that I'm totally failing once more, three questions at the time. So should we start, Iskra, with you and then Dave, you cover --

Iskra Reic -- Executive Vice President, International

So quick response in the market share. As I mentioned, the inhale market is -- I mean, the whole market obviously slowed down. So clearly, you will not see any major difference in market share. With Farxiga, you will see some difference and there is some decline in the end of the year.

And the reason is that the hospital capping that I mentioned really applies only for the 10 top performing brands. Clearly, as you know, Farxiga is competing with many different SGLT2 generics in the China market. So in December, due to the capping, you will see some decline. We saw the same trend, as I mentioned last year, and you would expect that to bounce back.

Pascal Soriot -- Executive Director and Chief Executive Officer

But net-net for important products like Tagrisso, etc., so far, we have seen no impact. Of course, we looked at that because market share is the best way to actually assess whether you're impacted. I mean, the market moves up and down, we see no impact at all, yes. Early days and so far, we only have hospital data.

We need a retail data. It takes more time to get there. But it's very encouraging to see our market share actually not moving differently from what we would expect. Dave you cover, Part D.

David Fredrickson -- Executive Vice President, Oncology Business

Yes, please. So I think the first point we saw on Part D is that the IRA we've continually said we think is manageable, it's part of guidance, it's in our outlook. So it's built in. So why do we think it's manageable? Well, first and foremost, it predominantly affects our oral oncology portfolio.

There is some biopharmaceuticals and rare disease impact. But in terms of where we see the greatest impact it's on oral oncolytics. There is a downside pressure of the increase manufacturer liability that now is happening in terms of picking up what was previously catastrophic. But there is a partial offset, and we saw that happening in 2004 from improved adherence and compliance on medicines and also lower free drug utilization.

And that volume is directly a result of improved patient affordability. And so that's the first dynamic for manageable. I think the second thing that's most important here is that we just look at the growth opportunities that we've got in 2025, right? So Tagrisso, we have continued opportunities, ADAURA, LAURA, FLAURA2; Imfinzi, HIMALAYA, ADRIATIC, CASPIAN, NIAGARA; Enhertu, DB06, DB04, DB03; and Truqap. Those are all in hand.

And so it allows us to be able to work through the headwind that we're getting in from IRA and that's why it's included within our outlook.

Pascal Soriot -- Executive Director and Chief Executive Officer

Aradhana?

Aradhana Sarin -- Executive Director and Chief Financial Officer

So just to build on Dave's point, the guidance, especially the gross margin guidance that I provided in terms of 60 to 70 basis points, that does include the net effect of the IRA. Again, we haven't given an absolute quantification, but that as well as the PPP as well as some of the impact from biosimilars, that's included in the gross margin indication. As it relates to the $3 billion for past deal-related payments, yes, most of them are success-based. But success could not necessarily be phase 3.

Some of them have already happened with Daiichi, for example, but it could also be progression events. So when the product moves into phase 2 or into phase 3, which is also success-based, because obviously, we want to move them into the next phase if we weren't confident. So yes, all of those related to. Some of it is Daiichi but also CinCor.

Again, if baxdrostat reads out positive, again, the CD19/CD3, so it's a multitude of smaller payments that are all progression or success based.

Pascal Soriot -- Executive Director and Chief Executive Officer

Just since we talked about Part D, keep in mind that basically, the headwinds we have in 2025 are, of course, IRA, two is VBP China, we mentioned it. Another couple of smaller ones, Brilinta patent expiry and the usual maybe more intense this year cottage industry of price cuts and rebates and whatever in Europe. But the momentum in the portfolio and in the new indications we hope to launch, certainly will continue to support our growth and move through these challenges in 2025. There's one last question on the table.

Jo Walton -- UBS -- Analyst

Thank you. Jo Walton from UBS. A couple of clarifications, I think. Aradhana, I didn't catch what you said about the gross margin impact for 2025.

Could you just tell us again what you're expecting to happen there? You spoke very quickly. And is that something that we should continue to see through into 2026 as well? Or is it just a one-time impact? And just to go back to Part D again, if we can. You say you -- are you already seeing increased adherence. In 2024, the payment levels were lower but they aren't as low as they're going to be in 2025.

So are you anticipating a further improvement in adherence? And is there any chance of things being even better in the first quarter because of the all-you-can-eat buffet that you get -- if you pay your $2,000 across the year rather than have to pay a big lump sum in January? So just whether we should be seeing anything in the short-term. Thank you.

Aradhana Sarin -- Executive Director and Chief Financial Officer

So I'll address the gross margin one. So the indication is more around the -- so I said 60 to 70 basis points impact on gross margins. And a lot of that comes from the Part Ds -- the net effect of the Part D payments. If you want to think about it, again, it's not a gross to net discount, but it does affect what you pay off of your revenue base, so that's included there.

When I say VBP, again, VBP when you get your price for VBP and their stock compensation and so forth, it affects your price, right? It doesn't affect necessarily your volume. There's some impact on volume. But you hope that once there's a reset on volume, obviously, generic will take some share and then you'll start going from there, which is what we've seen in other VBP situations. So again, that impacts your gross margin because your price is basically reset.

I talked a little bit about -- and Pascal said a whole bunch of other price actions which you see in Europe and other countries. Soliris biosimilar is another example, right, where we have been transitioning more and more of the market to Ultomiris. Again, Ultomiris is at a 30% lower price than Soliris is. As more market shifts to Ultomiris, again, it's slightly different, slightly lower gross margins than Soliris.

So it's all of those factors that -- and again, I don't think they are one-time factors, but that's sort of what we expect to continue. Dave?

David Fredrickson -- Executive Vice President, Oncology Business

Thanks, Aradhana. Jo, so yes, in 2024 in the oral oncology portfolio, we saw both a reduction in free goods as well as an improvement in adherence, or sometimes we talk about that as abandonment rates. And that came as a result of the co-pay cap being set at $3,300 last year. Now obviously, we didn't have the liability that we needed to pay for within that.

So 2024 was a year where the co-pay was capped but there wasn't the 20% liability. The payment structure was still as it existed before. And so that's one of the things that changes within 2025. But I think that very importantly, we've had this as an opportunity to help our reimbursement teams and our account managers engage with U.S.

customers to understand how they can work together to create education around the new opportunities to be able to think about where charitable programs need to be used, where they might not need to be used and to be able to have an understanding for how the benefit design has changed. And I think that there's education around that. That's one of the things that's resulting in patients being able to be on medicines that are not through charitable foundations. And then the charitable foundations are able to have more money available to them because of the co-pay caps to be able to serve more patients.

So it has really been, I think, in many respects, a real improvement in terms of affordability resulting in higher volume on the medicines. And I do expect that we'll see that continue into this year, probably not to the same degree of the bump that we saw when we went from uncapped to $3,300 and now $3,300 to $2,000.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Dave. Can we move to another table?

Jo Walton -- UBS -- Analyst

Dave, you mentioned the secondary effects if they're -- you're seeing in the commercial set.

David Fredrickson -- Executive Vice President, Oncology Business

No, we're not seeing secondary effects into the commercial set.

Pascal Soriot -- Executive Director and Chief Executive Officer

Sachin, we move to this table and we'll get to this table and move there.

Sachin Jain -- Analyst

Sachin Jain, Bank of America. Given it's a pipeline -- two pipeline questions on the two assets you called out on the slides. So the first one, I guess is for Ruud on bax. Of the greater the $5 billion peak, how much is in the resistant hypertension opportunity we're getting this year? And I wonder if you could just give us some feedback.

If you deliver the data as per phase 2, what's your physician feedback on adoption of this therapy in a heavily genericized market and third, fourth line agent as a common as pushback I get? And then the second question is on the third. I think investors are generally very confident in SERENA-6 because of the mutant population, but there's been lower confidence in frontline lower mutation incidence. So I wondered if you could just touch on hypotheses, and then you're confident you touched on biology, but some of the other stuff we hear from physicians potentially delaying ESR1 mutations endocrine sensitive or combination therapies. Just wonder if you could touch on other hypotheses how you are confident.

Thank you.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Sachin. It's nice to move to growth opportunities away from headwinds. So Ruud and Susan, maybe?

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Yes, let me take the first one. So the baxdrostat is the combination of the mono components as well as the combination of baxdrostat at Farxiga or dapagliflozin. So that's one. As you can imagine, this will be a crucial for baxdrostat, and we are doing an enormous amount of market research.

And it is clear that the high unmet medical need is very clearly resonating with cardiologists and physicians in internal medicine. I think the big challenge is going to be the GPs. Because a lot of those patients are undiagnosed or not well treated in the first line. And so we're working very hard in order to find a way in order to educate the first line moving forward as well.

But there is no doubt that this new class of medicine, this new way of treating resistant and uncontrolled hypertension, is resonating very well with the specialty care group of physicians.

Pascal Soriot -- Executive Director and Chief Executive Officer

Before we move to third, let me just add that, if you look at kidney disease, which is a total epidemic in the world, 800 million people have kidney disease today, and it's growing. 40% of those patients have kidney disease from hypertension, 40% from diabetes, and the rest is few other reasons. But 40% of these patients. Now, if they develop kidney diseases because they have hypertension, that is not properly treated, and their blood pressure is not controlled.

And so, we believe that an agent that helps bring those patients to blood pressure control and also potentially affects aldosterone, because we believe that the effects of aldosterone, deleterious effect of aldosterone on the kidney, the heart, are totally underestimated. So if you affect aldosterone and you control blood pressure, you really have a very positive effect on kidney disease in particular. Susan, do you want to cover the third?

Susan Galbraith -- Executive Vice President, Oncology Research and Development

Yes. Thanks for the question. So again, the data that has been seen for the current SERDs have been in later line trials to date where the proportion of patients that are truly endocrine sensitive is lower. And I think that's why you've seen the benefit concentration in the ESR1 mutants.

Just as a reminder, and as I said, we saw activity in the overall population with a hazard ratio of 0.58 versus fulvestrant, which is the currently available SERD. But we know that fulvestrant doesn't maximally degrade the estrogen receptor. As a reminder, when you go into the first line in SERENA-4, the comparator is with an aromatase inhibitor that doesn't degrade the receptor at all. And that's why we think you're going to have activity in the ESR wild-type.

And again, that builds on that hazard ratio of 0.58. Overall, it wasn't just in the ESR1 mutants that we saw activity. And then we've enriched the patient population in SERENA-4 for patients that are likely to be more endocrine sensitive. So in addition to them being first-line, which obviously enriches for endocrine sensitive.

They had to have adjuvant endocrine therapy of more than two years without progression. So again, those patients that progress rapidly are the less endocrine sensitive. You had to have a treatment-free interval of more than 12 months since completion of adjuvant therapy without progression unless they'd had tamoxifen. And I think those features that we've enriched for, were carefully chosen in order to maximize the probability of technical success for SERENA-4 as well as for SERENA-6.

Sachin Jain -- Analyst

Sorry, the bax peak cell split mono versus combo. Just to get an idea of how you think about the mono opportunity this year.

Pascal Soriot -- Executive Director and Chief Executive Officer

Rudd?

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

So sorry, Sachin?

Sachin Jain -- Analyst

Greater than $5 billion. Do you have a split of that mono versus combo? The study this year is obviously the mono.

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Yes, but we haven't disclosed that, Sachin. So and this is a relatively highly competitive field with two. So we have said it is substantial on both sides, but we haven't given the split.

Mattias Haggblom -- Handelsbanken Capital Markets -- Analyst

Hey. Mattias Haggblom, Handelsbanken. So two questions for Sharon, please. So first on the ongoing phase 2 investigating use of the oral GLP1.

So I'm curious to hear how confident you are. The 26-week duration of therapy for the primary endpoint is enough to meet the recently revised FDA guidelines. And if you can talk about enrollment pace in those studies. And then secondly for the oral PCSK9 with phase 2b date and how confirmed for HCC in March, help me frame expectations of LDL reductions once the abstract from ACC is out and perhaps talk about timelines to a phase 3 start.

And perhaps remind me how you win over Merck's oral peptide that has phase 3 trials reading out later this year. Thanks so much.

Sharon Barr -- Executive Vice President, BioPharmaceuticals Research and Development

Sure. I love those questions. So thank you. Your first one was about AZD5004.

That's our oral GLP1 and we've been very public about the progress of that. We released the data at Obesity Week in November of last year. This is a true small molecule. We are envisioning this as a molecule that we are developing both as a monotherapy and in combination with other small molecules already in our portfolio.

I mention that because we are moving beyond short-term weight loss targets and really thinking about the interconnectedness of cardiovascular, renal, and metabolic disease. So the first step is our two phase 2b studies, one for patients with obesity or who are overweight and one for patients with Type 2 diabetes. Those are the VISTA and APRICUS studies. Both are enrolling well and we are on track for the timelines that we previously mentioned.

So I'll move on then and speak about our oral PCSK9 which was your second question. This is AZD0780. So we have completed the phase 1 data and we released those last year and in those data we showed that we were able to reduce LDL at 50% on top of statins, 78% from baseline. We have just completed the phase 2b study pursuit.

It we will be releasing those data next month. So hold your breath. But I would expect to share a story that is broadly in line with our phase 1 data. How do we differentiate this molecule from other PCSK9s? Well unlike some of them, it's orally bioavailable.

Unlike the other orally bioavailable molecule, it is a true small molecule. It doesn't require a permeability enhancer and it doesn't require fasting. There is no food effect associated with this. So it is well suited to use as a monotherapy, but also potentially in combination with other molecules in our portfolio because it is a small molecule such as the one that I just mentioned, ACD5004 again addressing the interconnectedness of cardiovascular, renal and metabolic disease.

So it has a favorable PK profile, it sets us up well for success and it lines up in a portfolio of small molecules that really allows us to address interrelated disease.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Sharon. Maybe Mattias, I mean differentiation is one thing, but I think the most important part is to create this market for PCSK9. And two companies doing this is far better than only one. If you think of PCSK9, they're fantastic drugs.

Problem is they're injectable and expensive. So in the U.S., you can sort of get them. But in Europe in most countries, you have to have an event to be able to get a PSA scan and reimbursed. And the steps are complicated.

You have to have a recommendation from a cardiologist. Often you have to get approval from the payer before you can get it. If you move to an oral agent that is easy to take and then priced at the appropriate level, you can definitely expand the access to these very important medicines and then you can go into the emerging markets where also the needs are enormous. So I think really expanding this PCSK9cannon market is going to be a very fundamental priority for our commercial organization.

Richard Parkes -- Analyst

Yes, Richard Parkes from BNP Paribas Exane. I've got one for Susan and one for Rudd. Firstly for Susan, you're obviously making a push into next-generation PD-1. Bispecific you don't as far as I'm aware have a VEGF in development currently.

But you do have a TIGIT where I think confidence in that target has been damaged by recent data. So in terms of VEGF, is that something you would address through partnerships and do combination studies with Dato-DXd? Or would you develop something internally? And can you talk about your confidence on TIGIT still and the bispecific? Then the second one is for Ruud. You specifically talked about continued growth in the asthma biologics franchise, but you do have GSK coming with a six-monthly depemokimab in the relatively near future. So can you talk about that competitive threat and how you manage to -- how you plan to manage that?

Pascal Soriot -- Executive Director and Chief Executive Officer

Susan.

Susan Galbraith -- Executive Vice President, Oncology Research and Development

OK. So again, we presented data from the Artemide-1 study at the World Congress on Lung Cancer for rilvegostomig in non-small cell lung cancer. And again, we focused the development of this asset on the higher end of the PD-L1, expressing agents, which is the area where I think the data are most encouraging for the TIGIT mechanism. If you just come back to those data, if you look at the PD-L1 greater than 50%, actually we had a 62% response rate in that population and a median PFS of more than 10 months, which is actually, with all the caveats of cross-trial comparisons and small sample sizes as a health warning, that's in the same range as the other bispecifics, including the ivonescimab data.

What we also have is in the 1% to 49% patient population, again, encouraging data with that asset compared to what you'd expect with a PD-1 agent alone. And importantly, because it's a Fc-silent molecule, it's good combinability with chemotherapy with good safety and low discontinuation rate. I think they have contributed to some of the failures with combination data that we've seen with other molecules. We do have some phase 2 trials ongoing for combinations with VEGF targeted combinations, for example, in our HCC and gastric studies as well.

The good news is that we've got good safety for combination of rilvegostomig with that agent. And I think where the VEGF mechanism has also shown on its own that there's activity, that is the place where you're probably most likely to see the interaction between both in I/O and the VEGF mechanism. So I think there's opportunity for us to build on the backbone of rilvegostomig with some combinations with VEGF-directed agents. That's something that we're obviously -- we'll be looking at as well beyond the HCC and the gastric studies that we've already got ongoing.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Susan. Ruud?

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Sure, I'll take the second one. So first of all, I think the market opportunity in itself is still very, very substantial. The bio penetration of biologics in the asthma segment, on average, is only 20%. So clearly, there's a substantial room for further improvement there.

Secondly, based on our own Fasenra, which is a two-month injection, we know that's important from a convenience perspective. But the end game is always efficacy. It's very important that physicians, but certainly patients, feel that efficacy is the most important piece. And the reason that Fasenra has performed so well in the severe uncontrolled asthma segment is that the efficacy is very high and the level of satisfaction is very high.

So in that sense, competition is not bad. But I think the bar in order to move Fasenra away from the market leadership currently are having the NTL5, I think, is very high. Equally, of course, we have an unprecedented possibility in China. We all get Fasenra hopefully later this year in NRDL.

We're clearly the market leader in China from a respiratory perspective. So in that sense, we are very bullish regarding the outlook of Fasenra moving forward despite potential more competition.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you, Ruud. Let's move to Steve Scala, online. Steve over to you. Can you hear us?

Steve Scala -- Analyst

Yes. So thank you so much. Two questions. First, regarding Tagrisso, is your confidence in the outlook predicated on growth in adjuvant? Or do you think Tagrisso will remain dominant in first line or perhaps both? And has the first-line outlook been influenced by the MARIPOSA OS data? So that's the first question.

Second question is the fact that this duty has been assessed against AstraZeneca in China suggesting corporate Astra has been implicated in the investigation. Previously, Astra was not part of the investigation. So if it's now part of it, what are the implications of that? Thank you.

Pascal Soriot -- Executive Director and Chief Executive Officer

Dave?

David Fredrickson -- Executive Vice President, Oncology Business

So, Steve, thanks for the question. On the first part of your Tagrisso question, we saw in 2024, very nice growth in ADAURA, LAURA, where we've launched it, but also a really strong launch to FLAURA2. And I'll note that FLAURA2 we've launched now in 65 markets across the globe. So we've had an opportunity to really get out and be able to tell the Tagrisso backbone story and then also the opportunity to be able to be in combination in FLAURA2.

As we look at the impact that MARIPOSA is having certainly the overall survival that has been shared as high-level results is something that -- anything at a year of overall survival, I think is catching attention of the community. With that said, based on the data that the community saw at ELCC in 2024, for FLAURA2, where we saw really very, very competitive FLAURA2 landmark survival rates of 80% at 24 months, 64% at 36 months. I think that there's a general expectation that FLAURA2 is also moving in absolutely the right direction in this regard. And the utilization that we're hearing is for MARIPOSA is a lot in second line and actually quite a lot of trial but not repeat use.

And the only last thing that I'd just say, let me take this opportunity. In my prepared remarks, I had mentioned that the market share was 85% in the U.S., and I should have said that, that was in Japan. So that was something that I had said. The global frontline EGFR market share is 75%.

That's inclusive of the U.S. And in Japan, it's higher at 85%. So that's just something I wanted to clarify.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Dave. And the second question, Steve, is relatively straightforward. The -- as I said before, the notice has been sent to the prosecutor's office, if AstraZeneca is found liable, the Chinese law is very, very clear, the implication is very clear, which is the company has to repay the import duties, so $0.9 million, $900,000 to be repaid plus a fine that is 1 to 5x the amount of import duties. So it could $0.9 million plus $0.9 million or it could be $0.9 million plus $4.5 million.

That's the implication and it's very, very clearly defined by Chinese law. Andy, you will tell me when we have to run out. We have to stop because I know some of you have to go to another meeting.

Emily Field -- Barclays -- Analyst

Emily Field from Barclays. Two on oncology. Firstly, on Datroway, a great label from a safety perspective with no box warning relative to other TROP2 ADC. Do you expect that to hold for a potential approval in non-small cell lung cancer? And then another question on the SERD, we will be seeing the all-comers results from the competitor giredestrant this year.

I was just wondering if you could help us understand why some of the molecular advantages of camizestrant over the competitor molecule. Thank you.

Pascal Soriot -- Executive Director and Chief Executive Officer

Susan?

Susan Galbraith -- Executive Vice President, Oncology Research and Development

Yes, sure. So obviously, we're still in discussions with regulatory authorities about the filing for [Inaudible] in the EGFR mutant lung cancer setting. But we did publish the safety data that's the basis of that filing earlier. So you can look at the adverse event profile that is there.

And I think within the EGFR mutant population. That's in line with the current label that you've got in the breast cancer setting. So we always have to wait for the final label, assuming that the rest of the filing goes well. In terms of the camizestrant molecule, I think we've got a very good potency.

We've got very good linear PK. We've got very good drug clean profile with all of the combination partners that we're looking to combine with, including all of the CDK 4/6s. The safety profile that we're seeing with camizestrant leads to an extremely low discontinuation rate, very low rates of the GI side effects, which I think is important particularly when you go into the earlier lines of therapy. People want to stay on drug for a long period of time.

So I think the overall profile that we have with this drug is really looking best in class from our perspective. Obviously, we've got to have the trial read out first, and then we can happily discuss the actual profile that we've seen in the phase 3 trials. But at this point, we're confident.

Simon Baker -- Analyst

Simon Baker from Redburn Atlantic. Two quick ones if I may. Just going back to rilvegostomig. Susan, could you give us your updated thoughts and you could touch on this on the scope for TIGIT as a target beyond non-small cell lung cancer based on what you now know? And then one for Iskra on emerging markets.

The growth ex-China look very good, if you could give us some highlights of sort of country-by-country where you are seeing that growth? Thanks so much.

Susan Galbraith -- Executive Vice President, Oncology Research and Development

OK. Thank you. So rilvegostomig, obviously, we've, in addition to the lung cancer indications with TROPION-Lung10 in combination with Datroway and the ARTEMIDE-Lung02 and Lung03 trials in combination with chemotherapy, we've got the ARTEMIDE-Biliary01 study, which builds on the TOPAZ data that we had with durvalumab in biliary tract cancer that takes it into the adjuvant therapy. That's I think I would say that the investigators are very enthusiastic about.

And then the next piece in terms of the expansion is clearly building on the combinations that we've already got with Datroway. There's also good combination capability with Enhertu and then with the other ADCs that we've got coming through the portfolio. I think there'll be significant opportunity. We are focused on those patient populations where TIGIT is likely to be more beneficial.

But that has been seen in indications also like gastric cancer, for example. And HCC cancer, you would expect activity from the TIGIT mechanism of action beyond what you see with PD-1.

Iskra Reic -- Executive Vice President, International

If you look at the emerging markets outside of China, as I mentioned, I mean, growth is quite impressive. It's another strong year to growth of 32%. And the emerging markets if you exclude China it actually represents up to 13% of the global revenues. And we are very confident and positive in the further growth in the emerging market.

And therefore, the answer to your question is very difficult because we actually see the super strong double-digit growth across Latin America, Asia, Middle-East and Africa areas and we do see the good reasons and the good -- many growth drivers to see that continue. And I think one important point is that across the emerging markets, we are actually launching our brand a bit later than when comparing with U.S. and Europe. If you think about that, I mean, the products like Breztri or like Enhertu are still to get the full maximum and full leverage across the international region.

So despite the headwinds that we will always see, as Pascal mentioned a bit of the pricing or the exchange rate, I do believe that underlying growth across all areas in emerging markets is to be continued across all therapy as well.

Pascal Soriot -- Executive Director and Chief Executive Officer

I mean, I think it's important just to add to this, it's important to remember that the population is there. The global population lives outside the U.S. and Europe and most of the population. And many of those countries are becoming richer, their economies are developing, more funds can be allocated to healthcare.

And we have the portfolio of products that address most pricing needs, medical needs and many of those countries. The other thing we've done is we've accelerated the approval of new products. In the past, these countries were sort of priority three, of course, U.S., Europe first, and we had a long delay between the launch in Europe or U.S. and the launch in those countries.

We've accelerated this. Team has done an amazing job and so we're bringing those medicines to all these countries much faster than before. So there's really good reasons to believe that we will continue to grow and in many, not all but many of these countries, we don't experience the impact of patent expiries like we have in the U.S. or Europe because those products are sort of sold as a brand, lower priced but less exposure to patent expiries and you just competitors with generics as opposed to losing it all when you lose patent protection.

Eric Le Berrigaud -- Stifel Financial Corp. -- Analyst

Yes. Eric Le Berrigaud, Stifel. Two questions. First, we do appreciate that your top priority is on top line growth both short and longer term.

But my question is on margin development. We were expecting margin to end at around 32% in 2024 and ended just above 31%. So you reiterated commitment to reach mid-30s by 2026, which leaves a gap by around 400 basis points over the next couple of years. Given the current guidance for 2025, it looks like the leverage will be quite minimal this year.

So it leaves a lot into 2026. So how should we think about this development? Are we right in assuming that mid-30s means 35%? Or could that be a broader range? And would you be comfortable reaching 34% or just to kind of a sense also for consensus adjustments? And the second question is on Airsupra. If I remember correctly, it was suppose to be a multi blockbuster in the end and you were probably more bullish than consensus. And the start is relatively soft and we haven't seen much of an improvement in even the fourth quarter.

So there was a lot of development around free sampling and probably formulary access. Is it getting better, moving into 2025? And should we expect a significant improvement on the products in 2025?

Pascal Soriot -- Executive Director and Chief Executive Officer

Aradhana? And then maybe --

Aradhana Sarin -- Executive Director and Chief Financial Officer

Sure. So we do expect to see operating margin expansion this year. So if you look at our guide for revenue and EPS and you can extrapolate sort of what the operating margin could be. So there is clearly an expansion between 2024 and 2025.

I also mentioned in my prepared remarks the impact that FX has. And again, that was not obviously the case in 2024, but when you look at where the currencies have moved particularly in the last two, three months, that does have an impact of, as I mentioned 20 basis points in on our margins for this year and 50 basis points, if you compare it to the first quarter 2024 rates. Other than that, I would say me and all the entire executive team is very much committed to achieving that mid-30s operating profit. So mid-30s is 34% to 36%, which is always what we have signaled.

And we have a number of initiatives, whether it's optimizing our commercial footprint, thing where we do work. So you've probably seen the hubs we have opened in Mississauga and Barcelona and Bangalore and other places, again taking advantage of work we're doing. We're also doing a lot of process improvements, whether it's in regulatory filings and so forth. So there are a whole bunch of different initiatives that are happening across the company on driving productivity while still supporting, obviously a very large and growing portfolio.

Pascal Soriot -- Executive Director and Chief Executive Officer

Yes. Ruud on Airsupra?

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Yes, quickly. First of all, what I'm still very excited about Airsupra. First of all, we see enormous volume, over 300,000 scripts in one-year. And that's also the challenge in the spirit of transparency.

One out of two scripts are not fulfilled at the pharmacy level because still of access issues. This is a very highly generalized market and clearly it's much more difficult than we expect this in order to get traction because Albuterol Ventolin has a very, very low price. And we don't want to compromise at this stage of the game too much our price. We want to sell it basically on the clinical features of Airsupra.

The other big piece of excitement is that we have published why these are the high-level results of the BATURA data, which further expands the potential of using Airsupra in the mouth asthma segment. And last but not least, more than 65,000 physicians in United States have already prescribed Airsupra. So it's all about access, access, access. We were making good progress.

Through the 1st of January we have now roughly a coverage of 60% of commercial lives. We have secured one very large Part D access. So it will take some time, the good news is of in-health therapies, the tail is very long. You see it yourself, the performance of Symbicort.

So we are very committed in order to capture this opportunity moving forward, and we are working very hard on the access situation.

Pascal Soriot -- Executive Director and Chief Executive Officer

Great. I mean, that when you launch a new product access is always something that takes time, even more so here because of the reason described. But we're making good progress and the important piece, I think, is BATURA that the study that Ruud mentioned. Because fundamentally, you've got to convince managed care of the economic value of reimbursing these products when they have, of course, generic, a bit older that they can offer patients, and BATURA data will certainly be very important during convincing them of the cost effectiveness of reimbursing a SUPER, the clinical data are very, very striking.

Justin Smith -- AllianceBernstein -- Analyst

Thanks, Pascal. It's Justin from Bernstein. I've got one for Marc on efzimfotase, just if you wanted to share any thoughts on the cost of goods versus Strensiq. And the second one for Aradhana, just if you could possibly give any kind of color on capex after 2025?

Marc Pierre Jean Dunoyer -- Chief Executive Officer, Alexion and Chief Strategy Officer, AstraZeneca

So in short, the cost of goods is [Inaudible] efzimfotase way under that of Strensiq. And our ambition is to be able to reach out to six times the number of patients as we do for Strensiq, not only for a cost of good reason but also because we are also going to address the adult population and a much wider regional expansion. So the cost of good is only one factor in this. The development -- the clinical development plan in both pediatric and adult is important, and the regional expansion where today Strensiq is still relatively limited to a certain number of countries.

And we are expanding year after year. But with efzimfotase alfa, this expansion will be much easier and much wider.

Aradhana Sarin -- Executive Director and Chief Financial Officer

As it relates to capex, I think a good way to think about sort of from a forward standpoint would be that these are all multiyear projects. So some of them we started last year or the year before, so like the API facility, the cell therapy we started last year. The ADC we will start this year, Qingdao, we started last year. So you should expect that these go for at least four or five years, same with the ERP project.

And so, this would be a good level for the next several years. Again, if there are new projects started, for example, if we have great success with the GLP-1 or something, then we'd announce those separately. But this is a good way to think that these are multiyear projects.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you. It was good you asked the question about the efzimfotase, because I think this product is underestimated. Potential we said is quite substantial. There's no competition.

Profitability will be good. The unmet need is important and large. So we believe it is going to be a very important product, not only for Alexion but for AstraZeneca. Should I take maybe the last question online, Andy, and then close.

So we -- sorry. There's still on the room. Sorry, I missed that.

Rajan Sharma -- Goldman Sachs -- Analyst

Hi. It's Rajan Sharma from Goldman Sachs. First question, just to follow up on the oral PCSK9 actually. Do you think that you need a cardiovascular outcomes trial or a positive one to get meaningful uptake? And what would be kind of your thoughts around initiating that trial, particularly thinking that you might need one for the oral GLP-1 as well.

And then the second question was just on AVANZAR and potential filing strategy there. Assuming that is positive on PFS, do you think that will be enough for a condition on approval?

Sharon Barr -- Executive Vice President, BioPharmaceuticals Research and Development

Sure. So I'll jump in and answer the question on the oral PCSK9. I appreciate the question. I recognize that we are just now completing phase 2 and planning for our pivotal study.

We're not going to comment today on what our plans are for outcomes trials. We have been public about our expectation for the need for outcomes trials in oral GLP-1. And it's a little early to comment on what we plan to do for AZD0780, but thanks for the question.

Aradhana Sarin -- Executive Director and Chief Financial Officer

In terms of PFS as an endpoint in first-line non-small cell lung cancer, there have been approvals with full approvals based on PFS. In general, the regulatory agencies are going to want to see a positive trend in OS and reasonable maturity at the endpoint. So those are just things to consider.

Rajan Sharma -- Goldman Sachs -- Analyst

One question. I appreciate you've got a 2030 target of $80 billion revenue, and that's more of an organic number. If we look at your balance sheet, you will start generating more capacity to redeploy capital. What are your therapeutic area capital allocation? I mean, I appreciate Oncology has been very attractive for you.

And when we started, TIGIT suddenly was very interesting, and people are now asking you if VEGF more interesting. So are there therapies where you think it's getting a bit more difficult to find incremental opportunities? Or you're still excited about equal amount of capital in all therapy areas?

Pascal Soriot -- Executive Director and Chief Executive Officer

Yes, it's a great question. The exciting part of our industry at this point is, it's also the scary part, I must say, is that, I mean, the innovation is incredible. And the speed of replacement of technology is incredible. And that's why I believe I continue to believe that being focused on a few key therapy areas and building competence, building expertise is fundamental.

Because you actually understand much better what are the promising new technologies or products that are emerging and how you develop them? How you commercialize them? And you have an end-to-end understanding of a specific therapy area. So our approach is really we continue to focus on oncology, respiratory disease, cardiovascular disease. Immunology, we want to address it through a few products we are working on, but also cell therapy, we believe, could be a very important angle to treat some of these immune diseases and, of course, finally, rare diseases. But we will continue to stay focused on this and build access to new technologies.

We've talked about ADC, T cell engager, cell therapy, bispecifics, radiopharmaceuticals. There is a whole range of technologies that have emerged in the last few years. And actually, there's reason to believe it will continue to happen. And it's actually fantastic, fantastic for patients, for medicine, fantastic for us to participate in this, bringing those medicines to patients.

The reason I was saying it's scary is that it actually keeps us all on our toes right? We have to make sure we actually scan the horizon constantly and we don't get caught with something that is coming from left field that actually replaces our products. I mean, you see it yourself, I mean, products coming out of the woodwork and really transforming the treatment of an indication. So maybe I'll take the online one and then we'll let you go. Gonzalo, Danske Bank, do you want to go ahead?

Gonzalo Artiach -- Danske Bank -- Analyst

Yes, can you hear me, guys?

Pascal Soriot -- Executive Director and Chief Executive Officer

Yes. Go ahead.

Gonzalo Artiach -- Danske Bank -- Analyst

OK. Great. Gonzalo Artiach from Danske Bank. Two questions.

One on Datroway. And what type of launch do you expect in the TROPION-Breast01 setting, previously growth potential in that population. I'm asking this because now DESTINY-Breast06 or Enhertu will come one line earlier. I was wondering how far to assume some patients will go through ADC sequencing so Enhertu followed by Datroway.

And the second question on baxdrostat, not in hypertension but in primary aldosteronism. How big do you think this opportunity is for the drug? I mean there is potentially phase 2 coming soon. So I was wondering what type of patients would benefit from baxdrostat in that indication? Thank you.

Pascal Soriot -- Executive Director and Chief Executive Officer

So, Dave, did you get it? Yes, OK. Good. Because the line is not very, very good.

David Fredrickson -- Executive Vice President, Oncology Business

Gonzalo, I'm pretty sure that you're asking basically a TB-01 market size and market opportunity question. So if that's not the question you're asking, I'm going to answer that anyway. The -- so as we take a look at this, I mean, I think that what we're certainly seeing here is that the size of the market, G7, about 35,000 fourth plus line hormone receptor positive HER2 negative patients, right? So that's the patient population that we're talking about here that's addressable. And so it's after ET, after chemotherapy.

And I think TB-01 really complements DB04, which is transforming the HER2 landscape, right? So the first part of this is that now with TB-01 at the lowest IHC scores, you've got an option to be able to treat with TB-01. But then as DB06 starts to expand into the earlier treatment segment, there's a portion of the population also that, in later lines, will have seen in ET and a chemotherapy in the form of an ADC that could also be considered for utilization here. So I think that you've got an opportunity, particularly in the null space and then also potentially in the HER2 low space, but HER2 low more likely being kind of after they've seen an ADC upfront. And I just would lastly say, all of this is part of a strategy in breast cancer to really make sure that there's an option for all patients presenting, right? The Camizestrant to replace backbone ET, Truqap to continue to have an opportunity in patients who can benefit from ER drive, multiple ADCs to replace chemotherapies within the space.

And it's a comprehensive breast program that we've put together.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thanks, Dave. Ruud?

Ruud Dobber -- Executive Vice President and President, BioPharmaceuticals

Yes. Let me take the second one. So this is a very difficult area in that sense it is highly underdiagnosed. The expectation is that 5% to 8% of patients suffering from hypertension have this disease.

The reason we are so excited about it is that physicians came proactively to us in order to do a study in this patient population because there's an incredible high unmet medical need. So once again, it's a ballpark figure, 5% to 8% of the anti-hypertensive of the hypertensive patients are suffering from this disease.

Pascal Soriot -- Executive Director and Chief Executive Officer

Thank you. So let me thank you all for your great questions and your interest in our company, and wish you a good rest of the day. Thank you very much.
