Sanofi (SNY) Q4 2021 Earnings Call Transcript

Published at 2022-02-04 16:13:08
Paul Hudson
Thank you, Eva and thanks to everyone for joining our call today, delighted to be here and together with the members of the executive team to take you through the updates on our business and financial performance. You may have noticed that the visual change to our materials, more clear, it’s more modern. I want to emphasize that as part of the transformation, simply nothing is off the table, including how parts of the business are named, or indeed presented. Going forward, we’ll be known as Sanofi across our businesses, and we continue to work to raise the standards of disease treatment and prevention. Let’s start with full-year view. We delivered a 7.1% sales growth this year compared to 3.3% last year. Dupixent grew across all geographies, and vaccines delivered another year of record influenza business with more than €2.6 billion in sales. The contribution of our other GBUs has also been critical. The core assets we prioritized in our General Medicines business grew 5.6%, now amounting to €5.8 billion together. And our consumer health business is catching up fast to close the gap with market growth. Bottom line, we delivered an EPS of €6.56, growing at 15.5%, and continuing the strong trend we set since 2019. We have again improved our profitability with a BOI that now stands at 28.6% at CER. This is driven by both, improved growth profitability, given the growing Specialty Care and GenMed core asset portfolios, as well as our discipline in spending. At the same time, the way we’ve set our financial targets allows us to keep adding to our early stage pipeline. I’ll talk a little more about that in a few minutes. Moving to slide 7, let me turn to our main transformation activities this year. We announced six bolt-on acquisitions to strengthen our growth areas in immunology, oncology, and vaccines. They’re perfect fit with our strategic priorities as outlined at our Capital Markets Day in December 2019. We’re still on the lookout for exciting business development opportunities, for example, our collaboration with Biond, which adds the new generation checkpoint inhibitor to our clinical pipeline. We also intend to unlock the potential of digital, data and artificial intelligence in drug discovery and development. This is the rationale behind our partnerships with Owkin and Exscientia to help us further accelerate our efforts in immunology and oncology. As we focus our efforts on building a sustainable pipeline, we’re also taking action to reduce our complexity, again, fully in line with our 2019 commitment. We have continued to divest brands from our established portfolio and moved more than 50 countries to a distributor model. The standalone model for consumer health is about 80% complete, and we started an ambitious program to reduce the number of consumer healthcare brands. The next major milestone for us this year will be the planned IPO of EUROAPI, which could create the second biggest API player in the world. Now, let’s move to what is at the core of our Play to Win strategy, developing breakthrough medicines and vaccines to improve people’s lives. Let me give you a few highlights of what has been achieved over the past 12 months to advance our priority assets and beat industry benchmarks in R&D productivity. We delivered seven positive pivotal readouts last year. The seven marks a major scientific advancement in our effort to provide protection against RSV for all infants. We’re about to begin global submissions one year ahead of our initial plan and we’re getting ready to launch for the 2023 RSV season. Dupixent has only begun to penetrate the large type 2 patient population in atopic derm and asthma. Last year, four additional indications delivered positive results. The year was also marked by eight major approvals for Dupixent, Libtayo and Sarclisa, as well as Nexviazyme in Pompe disease, which strengthens our rare disease franchise. Our R&D engine achieved remarkable milestone this year with 10 molecules entering the clinical pipeline from in-house research. It’s something that we have never achieved in the past. Our focus on three key therapeutic areas, immunology, oncology, neurology is increasing. We’re building an industry-leading immunology pipeline and have put our OX40-Ligand antibody, amlitelimab, on the list of our priority assets, which allocates additional funding to allow accelerated development of the program, a potential first-in-class and best-in-class treatment for a range of immune mediated diseases, starting with atopic dermatitis. Rilzabrutinib is in Phase 2 development as a potential oral treatment option. Trials in asthma and CSU are going to be open soon. Oncology keeps building with the amcenestrant first line study, AMEERA-5 already fully recruited, significantly earlier than planned, given the high interest in the study from the investigator community. In addition, we entered broad Phase 2 programs for our engineered, best-in-class interleukin-2 SAR’245, and our first-in-class CEACAM5 antibody drug conjugate to explore and accelerate the development in areas of high unmet need. In neurology, our scientists are continuing to build the body of data, showing the impact of tolebrutinib on human microglia, which supports the thesis that this brain-penetrant molecule modulates neuroinflammatory processes directly within the central nervous system. We will share new and important data at ECTRIMS just coming up shortly. We also have started Phase 3 developments of tolebrutinib for the treatment of Myasthenia Gravis, a chronic progressive neuromuscular disease that strikes more than 10,000 people each year in the U.S. alone. Advancing to slide 9, I want to highlight how we have strengthened the early stages of our clinical pipeline by adding 36 projects in one year. This speaks volumes about our commitment to build an industry-leading sustainable pipeline with a steady stream of new assets that could transform the practice of medicine. 2021 has also marked the creation of our mRNA Center of Excellence to accelerate the development of the next generation of vaccines, with the ambition to deliver a minimum of six clinical candidates by 2025. We shared with you the interim results of our first mRNA monovalent flu study and pivoted our platform to modified mRNA in record time. As we transform and modernize the Company for the long term, the teams also keep delivering robust performance and creating value in the short term. Our Q4 program is a good reflection of this. In fact, this quarter marks the first time that the Specialty Care business has led our business units by sales. Key growth drivers for Specialty Care with Dupixent 53% up compared to the same quarter last year, and our Specialty Care pipeline has grown to 87 projects in Phase 1 to 3 with 61 in our key therapeutic areas of oncology, immunology and neurology. So, with that, let’s start with Specialty Care, and Bill, over to you.
Bill Sibold
Thank you, Paul. It is indeed a very exciting milestone for Specialty Care to emerge as the largest business unit of Sanofi by sales in the last quarter. This milestone validates our commitment to execute on our business priorities and to be a leader in innovative medicines that change patients’ lives. The fourth quarter proved to be another remarkable period of growth for our Specialty Care franchises with €3.5 billion in sales up 21.3%, as mentioned by Paul earlier, Dupixent our truly transformative immunology mega brand delivered once again a stellar quarter with more than €1.5 billion of sales and higher double digit -- and high double digit growth across all regions. More about the brand performance in just a minute. Double digit growth of our oncology franchise in the quarter and for the full year was mainly driven by the continued launch execution of Sarclisa and Libtayo in their respective key markets. Looking ahead, we are on a trajectory to exceed €1 billion in sales in oncology this year, despite the continued decline of Jevtana due to generic competition for the product in Europe. Our rare disease business reported exceptionally strong fourth quarter sales, up 9.5%, driven primarily by higher demand across the Pompe, Gaucher and Fabry franchises. Notably, our Pompe franchise reached blockbuster status in 2021 totaling more than €1 billion in global sales. We are making great progress in the U.S. uptake of Nexviazyme, our recently launched next generation ERT for Pompe disease. We are actively working on establishing Nexviazyme as the next standard of care in global markets. We obtained marketing approval in Japan in November and have launched there. In addition, we look forward to a number of potential approvals in 2022 and continue to work toward approval in Europe from the EMA, where blood disorders franchise sales grew 2.7% when excluding lower industrial sales to Sobi. Growth of the franchise in the fourth quarter was driven by Cablivi, mainly due to additional launches in Europe and higher Alprolix sales in the US. High fourth quarter sales of neurology and immunology were due to the performance of Kevzara, which grew mainly because of the continued global demand for IL-6 receptor blockers and a temporary shortage of a competitor product, tocilizumab. As a result, we expect the demand for Kevzara, which is indicated for patients with rheumatoid arthritis to remain strong in the coming months. Strong growth of Kevzara was partially upset by anticipated sales declines of Aubagio and Lemtrada in the quarter. Now moving to slide 13. Dupixent delivered another year of outstanding performance in 2021, driven by consistent strong growth quarter-after-quarter in U.S. and ex-U.S. markets. Last year alone, Dupixent added €1.7 billion of incremental sales to the top-line, making it Sanofi’s number one growth driver. Annualizing now at more than €6 billion in sales, we continue to believe that we are just at the beginning of the journey for this mega brand. Over the last two years, the key contributors of consistent strong growth have been patient demand, the approval of new indications and the expansion in the younger patient populations. I’d like to remind you that, Q4 to Q1 growth is commonly impacted in the U.S. due to patient deductible reset. However, consistent, strong underlying demand quarter-over-quarter has resulted in Dupixent becoming the number one newly-prescribed biologic among each specialist we call on, including dermatologists, allergists, pulmonologists and ENTs. Outside the U.S., China continues to represent a major growth opportunity with more than 30,000 adult patients treated to-date. The launch is progressing strongly and according to our plans. Dupixent’s growth opportunity in China is bolstered by the early NRDL listing, which was just extended by the authorities in China, to include the 200 milligram dose, improving our access to the adolescent patient population. In atopic dermatitis specifically, we have been rapidly advancing our leadership, as new entrants come to the market in the U.S. Europe and Japan. We believe competition can further raise awareness and help unlock our full market potential in AD. Recent U.S. approvals of competitive AD treatment options have come with a significant delay and in some cases, safety concerns, which are reflected in their label. In line with our expectations, some new entrants have restricted indications at second line systemic therapies, which can mean use after Dupixent. We believe this further reinforces Dupixent’s best-in-disease clinical profile, balancing rapid and sustained efficacy with proven long-term efficacy. This strengthens our position as first line therapy in the growing AD market. At the same time, we remain focused on delivering milestones for future growth, including regulatory submissions of AD in children younger than six years old, and in eosinophilic esophagitis. In asthma, we received a positive CHMP opinion for Dupixent in patients as young as six years old, with a final decision expected by the European Commission in the coming months. We are also excited about the recent pivotal data readouts in prurigo nodularis, which I will discuss briefly on my next slide. On slide 14, the data points on the charts demonstrate impressively the consistent benefit Dupixent has shown across two Phase 3 trials, PRIME and PRIME 2. These data confirm significant improvements in itch and the appearance of skin lesions in patients who are inadequately controlled with topical therapies or for whom those therapies were not advisable. The pivotal data readout is also confirming that potential benefit of targeting IL-4 and IL-13 as the central drivers of type two inflammation in this specific disease, adding yet another indication for Dupixent, if approved. Importantly data from the PRIME and PRIME 2 studies were consistent with the well-established safety profile of Dupixent, in already approved indications. We are very excited about the opportunity in prurigo nodularis, given the high unmet need and lack of approved systemic therapies. We are on-track to begin submissions to regulatory agencies in the first half of this year. Moving to slide 15, I’d like to highlight two of our launch opportunities in 2022. Both new products exemplify our commitment to bring innovative treatments to the market and Specialty Care, addressing underserved and sometimes under ultra rare diseases, where there are fewer or no approved treatment options available. On the left side of the slide, we are eagerly expecting to obtain the FDA approval of sutimlimab with PDUFA date tomorrow, February 5th. Sutimlimab has been developed as the first treatment for cold agglutinin or CAD, and our plan is to begin launching the product in the U.S. through our existing rare blood disorders business operations. A rollout of launches is planned for Japan later this year, and in key European markets beginning in 2023. On the right side of the slide, the upcoming launch of olipudase alfa underscores our unwavering commitment to delivering innovative therapies for the rare disease patient’s community. Once approved, olipudase will be the first and only therapy for pediatric and adult patients living with non-CNS manifestations of acid sphingomyelinase deficiency, or ASMD, a rare disease that robs quality of life for patients and their families and also increases the risk of premature death. The clinical development program for olipudase has demonstrated positive results in two separate clinical trials in adult and pediatric patients. Data from the ASCEND and Phase 2 ASCEND-Peds trial evaluating a olipudase alfa served as the basis for regulatory filings. Turning the slide 16, efa, our uniquely engineered Factor VIII has the potential to revolutionize factor treatment for hemophilia A patients, pending successful completion of our ongoing Phase 3 trial. Efa is designed to maintain high factor levels for much longer than all currently marketed factor replacement therapies. The product profile aims at providing sustained protection at near normal factor levels for most of the week, helping patients enjoy normal levels of physical activity, coupled with a low treatment burden of a once weekly dose. Considering the winning combination of convenience with weekly dosing, therapeutic activity with unmatched factor levels, and a safety profile in line with other practice therapies, efa has the potential to become the factor therapy of choice, significantly improving quality of life for hemophilia A patients. With the potential to capture a significant share of the global $5 billion factor class market, we see high commercial opportunity for Sanofi territories, U.S. and Japan, addressing patients already on factor therapy and expect a rapid uptake once approved. We also believe that efa’s profile would be competitive against non-factor treatments, unlocking additional opportunities by converting a portion of the non-factor patient population to safe factor treatment. While we are still waiting to see the Phase 3 data, we’re looking forward to sharing the pivotal results with you, which we expect at the end of Q1. With that, I hand over to Thomas to update you on the vaccines business.
Thomas Triomphe
Thank you, Bill. Q4 performance in vaccines generated significant sales of €2 billion, including the strong increase in flu in Europe, as well as growth supported by our PPH and travel franchises. The lower GBU sales as of last year were mainly due to the U.S. influenza market. We have two factors combined; first, the low immunization rate due to the priority given to COVID-19 vaccination in November and December; and second, a record product shipment in the third quarter, leading to a 65%, 45% split for the Q3, Q4 period. The U.S. performance was partially offset by the strong Q4 demand in other geographies, especially Europe where Efluelda was very successfully launched. The PPH franchise recording a strong fourth quarter growth despite lower birth rate around the world, mostly driven by Pentaxim performance in China. Finally, we are also pleased to see some recovery of the travel franchise, even though we are still far from the pre-pandemic level. Of note, on a full year basis, despite the pandemic environment, all 5 vaccines franchises have demonstrated growth in 2021 compared to 2020, illustrating again the robustness of our vaccines business. Next slide, please? On the next slide, let’s look at our record flu performance in 2021 with a 6% growth over last year’s record. On the left chart, you can see that the impact from the U.S. market contraction was more than compensated by the strong performance of Europe and rest of the world. Let me be very clear. The U.S. sales reduction has nothing to do with our product’s performance. COVID boosters were given the priority by retailers and health care providers, and as a result, the total number of U.S. flu doses injected this season decreased by 17%. Despite that challenging environment, Fluzone High-Dose continued to expand market share and gained 3.5-point share in the senior segment in the U.S. In Europe, the stronger Fluzone launch execution in Germany enabled us to reach a spectacular 64% growth following the positive STIKO recommendation. I’m glad to report that for the first season, 3 out of 4 German senior citizens have benefited from Efluelda’s demonstrated protection beyond flu. The right graph shows the continuous progress of our flu franchise. All incremental sales in 2021 were driven by our differentiated flu vaccines, thanks to the proven ability to protect against cardiovascular events and against pneumonia hospitalization. For the first time ever, our differentiated flu sales represented the majority of annual sales, indicating that the importance of providing protection beyond flu resonates well with external stakeholders. I’m confident that our flu franchise will continue to grow in 2022 and that this year, we’ll see another record year. With that, I hand over to Olivier.
Olivier Charmeil
Thank you, Thomas. Moving to General Medicines on slide 19, we are encouraged by our performance in the fourth quarter. The execution of our strategy continued to deliver as planned and the focus on our core assets has consistently generated positive results in recent quarters. In the fourth quarter, General Medicine sales reached €3.4 billion which included sales from industrial affairs. Our core assets grew 2.1% and were up as much as 4% when excluding the effect of Praluent sales to Regeneron in the U.S. which ended at the end of 2020. We drove double-digit growth for both Multaq and Soliqua in the quarter, while Plavix growth of 7.5% was accelerated by the strong performance in China, where the product is already included in the volume-based procurement program for the second year and generated growth of 28% in the period. We are very happy about the performance. Praluent sales increased by 36%, excluding U.S. sales to Regeneron in the fourth quarter of 2020. Outstanding growth of the brand was particularly due to its performance in Europe, where it was recently relaunched in Germany. As highlighted during the previous earnings calls, Lovenox sales were slightly down. This is mainly due to the high base for comparison in the fourth quarter, which followed the introduction of the WHO guidelines for the treatment of hospitalized COVID-19 patients as well as some supply limitations. Our leading transplant franchise was strengthened by the consolidation of our new product addition Rezurock. Starting on November 9, Rezurock added €20 million of sales in the quarter. I will provide more detail on this exciting launch on my next slide. In China, Sanofi participated in the VB program for insulin in November. We are very proud of the results in the balanced out insulin category with Lantus and Toujeo. Sanofi was the only multinational company among the winners in category A, which is a product category that will receive most of the hospital volume allocations. Our glargine franchise remained broadly stable in the quarter, supported by Toujeo, and despite the price and inventory adjustment in China, in anticipation of the implementation of the insulin VBP, which is expected in the first half of 2022. Sales on noncore assets were lower in the quarter, in line with our expectations. The decline of 7.6% reflected the impact of product divesture, which are key to our ongoing strategic streamlining efforts. We are vigorously reducing the number of small product families with the objective to drive efficiencies and increase profitability. Moving now to slide 20. For the full year 2021, General Medicine sales reached €14.2 billion, which included sales from industrial affairs totaling €808 million. Importantly, our core assets were up 5.6%. This performance translates into growth of 7.6% when excluding the impact of Praluent sales to Regeneron in the U.S. Across our brands, Lovenox, Praluent, when excluding U.S. sales, Soliqua, and our established brands in the transplant business, Thymoglobulin and Mozobil delivered double-digit growth in 2021. The performance of our core assets in 2021 reinforced our confidence to deliver on our ambition to grow our core asset mid-single-digit CAGR over the period of 2020, 2025. For 2022, we expect another year of strong performance of our core assets. Despite a high base of comparison in 2021 for Lovenox, we expect sales of Lovenox in 2022 to be close to the level of 2021. Our well-established Transplant franchise is expected to continue the growth path, strengthened by the launch execution in Rezurock. Soliqua is also set to continue its growth trajectory, supported by differentiated clinical profile, leveraging the compelling SoliMix data. Soliqua is well poised for the competition with premixed insulin in its key markets. We are also very excited by the anticipated approval of Soliqua in China later this year. In China, the winning position of our basal insulin products, Lantus and Toujeo in Category A of VBP will enable us to deliver significantly higher volumes but at lower price. With the pricing effect in mind, we expect our total glargine sales, Toujeo and Lantus to decrease by around 30% in 2022 in China. Looking ahead, we aim to establish Toujeo as a basal insulin of choice in the large diabetic market in China and expect to make Toujeo an important growth driver for our business in China in 2022 and beyond. Our noncore asset performance in 2021 reflects the impact from the progress we are making with our portfolio streamlining efforts. As discussed earlier, we continue to reduce the number of nonstrategic tail product families. In summary, our 2021 achievements give us confidence in our ability to deliver on our commitment to stabilize sales by 2025, as compared to the 2020 base, and to maintain General Medicine BOI margin accretive for the group over the 2020, 2025 period. Now moving to Kadmon on slide 21. Let’s discuss the value proposition of this important transaction for Sanofi and our Transplant business. The acquisition was completed in November and represents a strong fit with our strategy. Kadmon’s key asset was approved in the U.S. last summer and receiving positive market feedback as highlighted on the slide. Rezurock has already reached 96% penetration in 80 centers, and more than 500 patients have been treated to date. As we shared on our last earnings calls, Rezurock is a first-in-class treatment for adults and pediatric patients 12 years and older, with chronic graft-versus-host disease who have failed at least two prior lines of systemic therapy. The prevalence is roughly 14,000 patients in the U.S., with steroid being the current standard of care in frontline cGVHD treatment. We estimate that 5,000 to 7,000 patients in the U.S. who are treated with steroids, fail in their therapy and require additional treatment. In the slightly more than four months in the U.S. launch, Rezurock generated sales of €44 million, of which €20 million were consolidated by Sanofi since the acquisition. Going forward, we plan on accelerating the geographic expansion. We will continue to leverage our transplant expertise to maximize Rezurock growth potential, capitalizing on our longstanding relationship with the transplant community. In conclusion, we are excited about this innovative new core asset for Sanofi and confirm that the Kadmon acquisition will be slightly accretive in 2022. With that, I hand over the call to Julie.
Julie Van Ongevalle
Thank you, Olivier. It’s been a year since we presented our strategic priorities with the goal to grow our priority brands above market growth as early as 2022 in key geographies. I’m glad to report that today we’re ahead of that commitment. Indeed, in 2020, we were losing share, and we were trending about 5 points below market growth. The latest market data shows that we have closed this gap. In November, on a rolling 12 months, we are at par with market growth. This, despite our absence in cough and cold and physical wellness categories in the U.S. and mainly driven by our priority categories in key geographies gaining share. These results show that the execution of our three strategic priorities to drive our business is starting to pay off. On our first priority of cutting and embracing complexity, we’ve been able to increasingly focus on our key brands and geographies, thanks to our simplification efforts. We have divested and pruned 111 noncore brands, a reduction of 40% of our total number of brands, which represents less than 1.5-point of our sales. We’ve also reduced our trademarks by 50%, our domain names by 30%, and are continuously working on simplifying our processes and ways of working. At the same time, we have embraced the complexity of our multi-local brands by reallocating investment to brands with the biggest growth potential and market share gain. On our second strategic priority, to become a true fast-moving consumer health care business, the creation of our standalone is a key enabler, and we’re on track. 80% of our legal entities are now live, and we integrated key functions like industrial affairs, all science-related functions and supply chain under one roof. The success of this is twofold: first, a significant increase in agility, in reaction to market and consumer needs. Cough and cold is a good example where we were able to quickly size the opportunity of the market rebound in Q4, resulting in market share gain in October and November, excluding China. This is a first in four years. In addition, as mentioned earlier, this helps us to revisit our ways of working and adapt them to the specificities of a fast-moving consumer health care business, for example, in consumer engagement, digital marketing or speed of innovation. A big focus has also been to strengthen our brand equities and campaigns beyond the pure science and quality of our products, which we already deliver. On our third priority to build our digital and data edge, the creation of our stand-alone here again has given us the opportunity to revisit and build fundamentals with a strong focus on e-commerce, brand sites, THC-specific CRM and third-party management systems and data-driven A&P allocation tools. Regarding our Rx to OTC switches, both programs continue to progress despite the pandemic. The team is actively working on the projects, and we continue to execute critical studies in accelerated fashion. For Cialis in the U.S., we have completed the self-selection studies and results have been submitted to FDA along with the protocol for a natural use trial. No erectile dysfunction, Rx to OTC switch project has gone this far. We are now waiting for the FDA feedback in order to proceed. For Tamiflu, we’re evaluating the status of the current flu season to determine if certain studies can progress. In the meantime, we have accelerated all studies that can be done without the presence of disease to keep the pace. On both programs, we should be able to share more next quarter. Turning to page 23. When looking at net sales performance, we have delivered 5.6% growth in Q4. Our organic growth is even higher with 7% growth in Q4 when excluding the impact of divestments. These results are driven by three factors: first, the progress we’ve made on the execution of our strategic priorities, as mentioned earlier; secondly, we benefited from the market rebound in categories like cough and cold; and lastly, we also benefited from COVID vaccinations, specifically in pain care. We will continue to focus our efforts to further deliver on our three strategic priorities that have proven to be working, with the ambition to build a true fast-moving consumer health care business and be at par with market. Let me wrap up by saying how much I am enjoying working with the team, driving the CHC business back to growth. With that, I hand it over to our CFO, Jean-Baptiste. Jean-Baptiste de Chatillon: Thank you, Julie. Let me start by highlighting some strong proof points for Sanofi transformation in 2021. First, we managed to increase full year gross margin by 120 bps to 71.3%. This improvement is linked to the growing sales contribution of our brands in Specialty Care on higher-margin vaccines products. It is also the result of efficiency measures in manufacturing which typically require a longer lead time before they become accretive to margin and are now starting to come through. As I said before, we are committed to continuing this trend of gross margin improvement. Second, we managed our OpEx in 2021 effectively and without disrupting the strong growth momentum. We successfully controlled the increase in OpEx and managing them to grow slower than sales, which was possible as a result of our rigorous prioritization. As before, we reinvested the vast majority of efficiencies generated during the year. Finally, let me briefly comment on another proof point of our transformation, headcount. When I took on the CFO role in 2018, the Company employed around 105,000 employees worldwide. With the ongoing transformation towards a more agile organization, we are now in a new phase with approximately 96,000 globally, and we continue to change our ways of working. We are embracing digital change, streamlining our portfolio and collaborating with partners and geographies to balance a reduced infrastructure while improving access to our medicines. On this path, we expect to end the year with a headcount closer to 90,000, reflecting a more efficient organization. This would represent a 15% lower headcount as compared to 2018 and would include the successful IPO of EUROAPI on existing plans. On slide 26, turning now to the full P&L for the fourth quarter. Company sales increased 4.1% at CER, driven by excellent growth of dividend and other Specialty Care franchise as well as consumer health. Business operating income grew 6.9% at CER, benefiting from improvements at gross margin level, which were driven by the favorable portfolio shift to Specialty Care products and efficiencies within industrial affairs. In the fourth quarter, we again saw an increase compared to last year with the margin improving 240 basis points. Business EPS grew 9.8% at CER benefiting from a slightly lower tax rate of 20.5%. Turning to slide 27. We have achieved around €2.4 billion of cumulative savings, of which €2.1 million were accrued through OpEx efficiencies as depicted by the bright purple boxes shown on this slide. In addition, we realized an incremental €300 million in COGS reductions over the last two years. Specifically, we achieved our target of €500 million savings in R&D due to prioritization of Specialty Care on exiting diabetes and cardiovascular. In addition, lasting efficiencies were generated by consolidating function across sites, improving our trials logistic, reducing cycle times through advances in data and digital, coupled with more agile governance. GenMed has been successful in reducing the complexity of its business, focusing on key markets, on employing a digitally enabled go-to-market model. G&A across all areas of Sanofi contributed €500 million of savings over the last two years, driven by smart spending initiatives, real estate efficiencies, a preferred supplier model on digitalization. In summary, we remain on track to achieve our target of €2.5 billion savings by end of 2022. Most of this year’s savings are again earmarked to be reallocated to fund our growth drivers and key programs in R&D. Moving to slide 28. Let me briefly comment on our strongly increased free cash flow. In fact, we doubled free cash flow since 2018, so we focus on improved business performance and change in working capital. Given the strong improvement in free cash flow in recent years, we were able to achieve our 2019 Capital Markets Day objective of a free cash flow increase of around 50%, one year ahead of schedule. On slide 29, we maintain our objective to continue Sanofi’s annual dividend policy, which is reflected in the fact that the company has consistently increased its dividend payments for the past 27 years. As a result of Sanofi’s performance in 2021, we announced that the Board has proposed a dividend of €3.33. Growing dividend remains an important element of our capital allocation, but it ranks behind our organic investment on business development in our priorities. On slide 30 we provide an outlook, highlighting expected business dynamics across sales and expenses. Focusing on the left part of this slide, you can see expected drivers of sales across our GBUs, including the continuation of strong growth from Dupixent, record flu season and maintained business momentum for the core products of Consumer Health and GenMed. As communicated before, we expect Consumer Health priority brands to grow above market in key geographies, resulting in growth for the entire business, but only progressively nearing market rates. At the same time, we also foresee overall GBU sales in GenMed to stabilize. The EUROAPI third party sales are currently consolidated in this business. Upon the planned EUROAPI IPO, 10 sales will be reduced by that amount going forward. On the right part of the slide, we expect gross margin to continue to improve due to product mix and efficiencies. R&D expenses are expected to continue to grow in line with our strategy as we keep streamlining our GenMed on THC business, we expect to generate around €500 million in capital gains throughout 2022. We estimate that our 2022 ETR, effective tax rate, to be around 19%, given the evolution of our product and geographic mix. This estimate is based, of course, on current tax legislation. So, on my final slide, slide 31, we expect full year 2022 business EPS to grow in the low double digits at CER. On our way to achieve our 2022 financial targets, we also guide to a BUI margin of 30% for the year. On foreign exchange, we see a positive currency impact of 2% to 3% based on January average exchange rate. With 9.2% EPS growth in 2020, our 15.5% EPS growth at CER in 2021, we are on track for a third year of double-digit or near double-digit EPS growth. I hand now the call back to Paul.
Paul Hudson
Well, thanks, JB. We expect 2022 to be another busy year with important milestones for our priority molecules and other pipeline programs. We’re looking forward to the results of four pivotal studies, including amcenestrant in second and third-line metastatic breast cancer as well as the Phase 3 results of efanesoctocog alfa in hemophilia. The readout of Dupixent in chronic cold induced to the carrier may add another dermatological indication, addressing a population of 25,000 patients in the U.S. alone. We also anticipate making further important pivotal trial decisions especially in oncology and vaccines. Moving to slide 34 and to ESG. You may remember that our social impact strategy was approved by the Sanofi Board a little more than a year ago. Our renewed contract with society is fully aligned and embedded with our business strategy and ambitions. We made good progress across all our four pillars. Today, I would like to highlight some achievements in the area of affordable access. The mission of the Sanofi Global Health unit we created last year is to increase access to essential medicines in some of the world’s poorest countries. In the area of malaria, TB and non-communicable diseases, we have increased both the number of patients reached and the number of countries. In addition, Sanofi is committed to helping 1,000 patients living with rare diseases who have no access to treatment. We donated again more than 100,000 vials in 2021. This builds on a 30-year humanitarian commitment to patients suffering from rare diseases such as Fabry, Gaucher and Pompe diseases. Moving to slide 35. As we look into the 2022 calendar, we will update you every quarter on our new initiatives happening across the four pillars of our ESG strategy. This quarter, we wanted to put the focus on access. We are proud to announce our partnership with Medtronic Labs and the launch of a multi-country, multiyear collaboration in the field of noncommunicable diseases. Together, we will leverage digital health and a community-based approach to improve disease awareness, diagnosis and management of diabetes and hypertension in strong collaboration with health system partners. The public health burden of NCDs is staggering with 35 million deaths globally, of which 28 million occur in low to middle income countries every year. This project will contribute to strengthening health systems as they build towards universal health coverage and sustainable development goals. On my final slide, let me touch on some planned events in the first half of this year. As mentioned, we expect to have further tolebrutinib data presented at ECTRIMS, and we’ll organize a virtual event around this. Invite will be sent out shortly. We also plan for an update on our immunology pipeline, including Dupixent in late March. As part of this update, we will revise upward our peak sales potential for this medicine. We are currently finalizing our plans for an event focused on ESG that we hope could take place in the June-July time frame. Well, let’s open the call now for Q&A. Eva Schaefer-Jansen: Thank you. We will now open the call to your questions. We would like to ask you to limit your questions to two each, so we can call up a number of the participants. You have two options to participate: Click the raise hand icon at the bottom of your screen, you will be notified when your line is open to ask a question. At that time, please make sure you unmute your microphone; or option two, submit your questions by clicking the Q&A icon at the bottom of your screen and your question will be read out. Can we now have the first question?
Operator
Yes. The first question comes from Wimal Kapadia from Bernstein.
Wimal Kapadia
Great. Thank you very much for taking my questions. Wimal Kapadia from Bernstein. So first, can I just ask on the U.S. flu business, declined year-on-year. Thomas, you flagged a 17% market contraction in volumes. So, could you just provide a bit more color on your expectations for the volume value mix for the U.S. in ‘22? What was the level of coverage in ‘21? Was that actually below historical pre-COVID levels? And if so, should we be getting a nice bounce in coverage in 2022, specifically to the U.S.? And then my second question is just on the OX40. We had some data last year for the OX40 program, which is now a priority asset. Just curious how you’re thinking about targeting the OX40 versus the OX40-Ligand. And then, I’d love to hear how you think about the duration of effect just given looking at Amgen’s drug, it looked rather compelling on that front. Have you seen anything from your own asset suggesting a similar efficacy profile with time? Thank you.
Paul Hudson
Thank you, Wimal. Great questions. Thomas, flu, coverage, read across for ‘22?
Thomas Triomphe
Thank you very much, Wimal. Indeed, you understood very well that the U.S. flu situation in 2021 was a very specific U.S. situation, with minus 17% on the overall volume for the U.S. And what that means that it was lower than 2019. Very specific to the U.S. again, as you’ve seen from the other markets, and completely linked to the COVID-19 specifications. You know very well that there was a lot of confusion with different age indications being licensed at the time, and a lot of discussion on the boosters. So, definitely, we don’t see that as a play moving forward for 2022. Because, of course, if you end up being in 2021 with the U.S. vaccine coverage below 2019, that gives room for growth. So, we are very confident about 2022. We expect to see both volume and value increase in the U.S. versus this year. To give you an example, and I think it’s a good illustration of what could happen in the U. S. for flu in 2022. I think everybody has understood that there needed to be some fixes on the U.S. flu coverage. And CMS has very interestingly decided to increase the flu vaccine administration fee from $17 to $30 per dose for the season in H2 ‘22 in the U.S. So, I think there’s going to be a strong CDC understanding as well as strong retailer preparation to make sure that 2022 is very different from 2021. And that’s why we’re expecting a record flu season overall for Sanofi Pasteur and indeed, an increase of flu in the U.S. in ‘22 versus ‘21.
Paul Hudson
Thank you. Thank you, Thomas, great to hear from Sanofi Vaccines. John Reed, OX40-Ligand. I think the question from Wimal is about duration and efficacy and some -- maybe you have some thoughts on tolerability as well?
John Reed
Yes. I think, it was about OX40 the receptor versus OX40, the ligand. And we prefer the ligand because it is induced on antigen-presenting cells. So, its quantity and the body is less, whereas OX40 is more heavily expressed on a consistent basis and can mean that you’re going to have to dose higher to neutralize it. But more importantly, I think, than that is the fundamental difference in the mechanisms of our molecule, amlitelimab, coming from the Kymab acquisition versus the Kirin antibody that Amgen has accessed. The Kirin/Amgen antibody is a depleting molecule that actually kills the cells that express OX40, whereas we have a non-depleting antibody that modulates OX40’s pathway. The downside of depleting is that both effector T cells, which are contributing to the autoimmunity, but also regulatory T cells that we need for suppressing autoimmunity, express OX40. So, over time, you’d have the risk of depleting those necessary regulatory T cells with a depleting mechanism. So, we feel that in terms of long-term safety and durability of the effects, that a non-depleting antibody targeting the ligand is really a superior way to go.
Paul Hudson
Thank you, John, couldn’t agree more. Next question?
Operator
The next question will come from Richard Vosser at JP Morgan. Richard?
Richard Vosser
Two questions, please. First one just on flu as well. Just could you talk about your manufacturing capacity and supply and how that will develop? And the demand that you might see for high dose beyond Germany in Europe? And then, second question, there’s clearly been quite a lot of interest for consumer assets early on this year. Does that lead you to change or accelerate any of your plans for the consumer business going forward?
Paul Hudson
Thanks, Richard. First of all, I’ll compliment Tom and the team on what they’ve done with the high-dose launch and particularly this year and remotely and incredibly in Germany. So, the question is supply and beyond.
Thomas Triomphe
Thanks, Richard. Definitely no concern at all on U.S. or non-U.S. flu supply. We are very confident. You know very well that last year, we’ve added a new flu building in Swiftwater. You know also that we are further investing into additional Fluzone High-Dose antigen for the mid- to long term with the Canada plant. So really moving forward on that and feeling very confident on supply for this year. Of course, as every single year, we are always receiving the northern hemisphere season at the end of February. And at the end of the Q2 call, usually, we’ll take that moment at the Q2 call to make a little bit of an update on supply and phasing for Q3, Q4. When it comes to demand, as you’ve highlighted, the Sanofi Vaccines team have done very strongly this year in Germany. We expect this to further grow. There is room to grow in Germany. When it comes to other markets in Europe, we are going to introduce in ‘22 in a couple of new markets in Europe. But you know very well when it comes to vaccines and flu introduction, it’s about having preferential recommendation. It’s about having reimbursement. So, we’ll start new countries in Europe little by little, until we have the right reimbursement in place, and then we will provide a supply.
Paul Hudson
Thank you. Thank you, Thomas. The consumer question. I think I got where you’re heading, Richard. I think the thing for us, we go back to what we said at Capital Markets Day, December 2019. We thought we could grow faster than we were growing. We thought we could carve in increased agility, accelerate growth, make better choices, prioritize, leverage e-commerce and run fast all the way to the switches. And I think Julie and the team have done an incredible job, frankly, on doing that, and we’re really delighted with the progress we made. We know a lot happens outside with other companies and different things, but we know the choices that we made back in ‘19, and we’re very happy with how things are performing. Okay. Next question?
Operator
The next question will be from Luisa Hector at Berenberg.
Luisa Hector
Possibly for JB, but you mentioned the headcount reduction, I just wondered if you can give us an update on the EUROAPI spend, timing and gating items. And then, also on gross margin, so clearly, very good progression. So, you’re working very hard on this, and it’s paying off. Can you guide us to whether to think about a continued improvement through 2023 when Aubagio generics arrive?
Paul Hudson
Okay. Thank you, Luisa. So, JB, you always get the fun ones. So, maybe -- there’s a EUROAPI question. It was partly related to headcount, you may want to go a tiny a bit broader. And then, of course, gross margin, and why don’t we go from there? Jean-Baptiste de Chatillon: Yes. So effectively, in trying to transform, we have the new business model operating in some countries commercially, but we have also this API activity, which is going to be a leader in its field. And so, the IPO is announced for H1 2022. We are on course to do this. So yes, as planned, Luisa, we’re looking forward to make it happen in H1. On the gross margin. Yes, effectively, we’ve delivered on ‘21. We are guiding again on improvements. On the midterm, I won’t make a gross margin guidance multiyear. But is there something which is a strong element you have to keep in mind? Is that on our main asset, Dupixent? We are going to have quite a transformative journey in terms of COGS, which should really help us at least to neutralize any price erosion we could have because we are looking at implementing new manufacturing processes that will deliver strongly in terms of COGS improvement. So that’s a clear piece.
Paul Hudson
Thank you. And Luisa, you didn’t ask, but I’m -- me, but I’m glad you asked the questions because there’s a huge amount of work, while we’re advancing the pipeline to 36 new programs in early development, the 6 acquisitions. I think what does get missed out of our discussion a little bit occasionally is the fundamental work that’s going into reshaping the company. The rightsizing the company, of course, but more importantly, we’re having an IPO in the first half of this year. At the same time, we’re carving in a consumer business. And on all these things, we’re outperforming whilst doing them, whilst delivering on the science and the overall financial performance and the commitments we made to the Street for ‘22. So, we really feel like the level and scale of transformation that are happening is perhaps not fully understood, and it’s okay. But it’s extensive.
Operator
Next question will come from Simon. Simon Mather at Exane. Simon?
Simon Mather
Loving the new branding, by the way. The first question is actually for JB. You’ve given guidance for 19% tax rate for 2022. If you look at consensus in out-years, it’s some 230 basis points higher. Just wondering if you can potentially comment on sustainability of this tax rate or how we should maybe revisit our expectations there. And then, the second one is just on Dupixent. Thank you for the update and time frames with respect to guidance. I mean I think it’s clear you blow everything out of the water in terms of safety and efficacy in atopic dermatitis. And I appreciate it’s early days, but maybe could you comment on any impact that you’re seeing or that you expect to see with the recent launch of tirzepatide in severe asthma? And feedback we may be getting from physicians? Thank you.
Paul Hudson
Okay. Well, thank you for the kind words on the branding. For those that haven’t followed it closely, it is the original font from our birth in 1973. And it’s also an opportunity for us to be a little bit more disruptive and unify the Company as well at the same time. So, I’m glad that it’s recognized. I think it’s more dynamic, frankly, and reflective of the comments I made earlier, how much the transformation is happening here. And from that high energy question to tax, Jean-Baptiste, to you. Jean-Baptiste de Chatillon: Thank you very much. Yes. It’s a nice trend on our effective tax rate, 200 bps. But effectively, as I said in my previous speech, it’s really something which is dependent on further changes in the tax legislation. We have structural good trends -- and let’s say that the underlying tax rate is like between ‘19 or ‘20. But, as we speak, I don’t know what will be the full impact of pillar two of changes of taxation in some other regions like the U.S. So yes, a good trend with the chunk -- a big chunk of it linked to our business on tax rate in France also, which is growing positively, but that could be disturbed in the midterm by other changes in other regions.
Paul Hudson
Thank you, J-B. Thanks also, Simon, for the compliments on Dupixent, which is frankly, incredible performance and led by Bill and the team. So Bill, comments about new entrants and early signals?
Bill Sibold
Yes. Well, thank you for the question. None of the new entrants are a surprise. For one thing, we’ve been planning on these. We’ve been waiting and in some cases, extended weights for the JAKs as they were almost a year delayed. And while it’s new competition in the U.S., we’ve had these competitors that have already launched in Germany and underway in Japan as well. So, we’re certainly used to them. And I think the one thing that they do is they really reinforce our best-in-disease clinical profile that we have. Just go back to the biology, targeting IL-4 and IL-13 that is fundamental to type 2 inflammation, and no other product has been able to show the profile that we have in any of the type 2 diseases and clearly starting with atopic dermatitis where we are the leader now. Asthma as well. The profile, again, we think is the top, the best profile that is in asthma, and we’re seeing really very promising signs all around the world of our ability to compete and win in the asthma space. Just one comment, as we have competition come into the atopic dermatitis market, it actually helps to serve to grow the market, grow awareness of atopic dermatitis, et cetera. And I -- as we’ve had competitors launch in other countries, as I said, Germany and Japan, we have seen market expansion. So, that’s what we expect. That’s part of our aspiration, to have a 25% to 30% advanced therapy penetration in atopic dermatitis over time. That’s one of the contributors. But the one thing that’s clear is that we are on top. We remain on top, and we believe being best in disease, we will stay on top.
Simon Mather
Sorry. Can I -- apologies to interrupt. Yes, I think I said tirzepatide. I put it on my brain. I meant tezepelumab in the U.S., is there any early feedback you could share?
Bill Sibold
Yes. No, there’s really nothing that we’re seeing. It’s still very early. We’re staying with the trends that we’ve seen.
Paul Hudson
Yes. Just to add a point to Bill’s -- which is I think the assumption is always it’s a zero-sum game. You know, say, with the JAKs, for example, the baggage, and you know with the 13s, it’s half the answer, missing the 4. So -- and you know that most of these mechanisms have failed in at least 1 of the indications that Dupi has already approved. And teze would probably be in that box, too. I think it failed in AD, if I remember correctly.
Bill Sibold
Yes. That’s right.
Paul Hudson
So, we’re -- on one hand, we’re the only medicine that will play in every indication. On the other hand, as Bill said, and I think it gets missed every time, a little bit of competition to help drive up penetration of advanced therapies is absolutely essential. And Bill’s comments about Germany should not be underestimated because we obviously will carry the education of these disease areas. But it’s good that others want to come in and try and do that, too. And in growing markets where you’re the market leader, it’s a very healthy place for us to be on behalf of patients.
Operator
Next question will be from Graham Parry at Bank of America.
Graham Parry
So, congratulations on getting an hour into the call without an AMEERA-3 question, but I’m afraid I’m going kind of break that. So, just wondering, have you accrued all the events now and in data lock? So, weeks long for Q1 readout on that study. And the elacestrant results, I think, have led to some concern in the market that oral SERDs only show benefit in ESR1-mutated patients who are obviously more rare in the frontline setting, and I think that’s leading to some pessimism around the potential in frontline. So, perhaps if you could just address that point. And then secondly, a question on M&A. You’ve done a lot of smaller pipeline deals of late. Obviously, biotech valuations have fallen somewhat at the moment. So, with the weakness that you’re seeing in biotech prices, are you seeing more value and opportunity perhaps to build out further in oncology where I think you’ve highlighted is still a key target?
Paul Hudson
Thank you, Graham. I didn’t hear the first part of your question. So right -- oh, it’s an AMEERA-3 question. Thank you for raising it. So, I’m going to toss it to John. John, I hope you heard it. It was the competition showed more efficacy, I think, in ESR mutation. And so, what’s the read across for us? And where are we on database lock and reporting it in Q1.
John Reed
Right, right. Okay. Graham, thank you. In terms of the activity of our SERD on wild-type versus mutant estrogen receptor, we’re fully active on both, whereas the competitor molecule is better on the mutant than on the wild type. So, that’s not at all a liability for us. And so, it is one of the differentiators of our molecule and one of the many factors that we think gives it a best-in-class profile along with the pristine tolerability. We’re -- we expect to have the data this quarter with respect to AMEERA-3 in late line metastatic breast cancer. I’m also pleased to report we’re fully enrolled now in the front line study in combination with the CDK4/6 inhibitor and that our first of our adjuvant studies is now open for enrollment. So, we’re making good progress across the spectrum from early to the late line in each of these indications where we think amcenestrant has a strong value proposition for women with hormone receptor positive breast cancers.
Paul Hudson
Thank you, John. So categorically, Graham, results in Q1. Okay, JB, M&A? Jean-Baptiste de Chatillon: I do think that our M&A activity is not related to the peak and trough of the valuation of biotechs. It’s much more dependent on the leadership of our R&D team and on John scouting for the right asset which is really fitting with our strategy, really fitting with our TAs. So, no specific impact from the current level of valuation. It will be a comedown. But, we are still on for bolt-on acquisitions, of course.
Paul Hudson
Great. Thank you. Next question, please?
Operator
Next question will be from Tim Anderson at Wolfe.
Tim Anderson
Thank you. A couple of questions. So going back to oral SERDs, we’ll be getting two readouts this year from two similarly designed trials, later line breast in your trial, and then Roche’s trial, both companies claim best-in-class. Do you think these upcoming data sets will help prove which company is right and which company is wrong in making that claim, or would that not become clear until we get additional trial readouts such as in the first-line setting? And then second, I would love to get your thoughts on Lilly’s lebrikizumab. They’re saying they think that will have a profile that’s very competitive to Dupixent. You talk about differentiation in ocular side effects. And I’m wondering what your thoughts are on them as a competitor. They do know the derma space well because of Taltz.
Paul Hudson
Okay. A few good things in there. John, given Roche’s data and our impending data, do you think we’ll be able to declare a winning profile this year?
John Reed
No. It’s a good question. I’m not sure that these late-line settings are the best place to really differentiate on efficacy. Where we do feel confident that we’ll be able to perhaps differentiate is on the safety tolerability profile where so far amcenestrant has really been delivering a best-in-class profile, whereas molecules from others, including Roche, have been showing safety signals around cardiac issues and in some cases, vision issues. So, I think that’s probably the best answer I can give you for now. I would probably be really looking to how the tolerability profiles hold up in these early lines as opposed to hinging a lot on the efficacy profile, given the -- a lot of the heterogeneity in these patient populations, you’ve see in the late line and therefore, the difficulty to really do cross-trial comparisons in an apples-to-apples way.
Paul Hudson
Thanks, John. I’d reiterate to everybody. We haven’t seen the data. We are optimistic that we’re in a good spot, and we look forward to getting it. You all know, I think, it’s a small indication if we are successful. So, in terms of value perspective, it’s not as important, although it may bring benefit to those that need it, let’s be frank. But from a confidence perspective, we know it’s important to everybody. So, when we have the data, you’ll be soon after us in terms of knowing. As for -- I do think whereas in most of the areas I’ve worked in tolerability inevitably plays a part, particularly this as we move earlier lines and John, I think, touched on it, tolerability will be a key differentiator. And if I understand correctly, the competitor, you referenced at a lower dose, continues to have cardio tox challenges. So that -- we think those things are going to be very, very important over the longer term. Bill, IL-13s, Lilly are saying that they have a winning profile.
Bill Sibold
Yes. Well, thanks for the question. As Paul said, I think, earlier on with the IL-13, it’s incomplete. It’s missing the IL-4. So we think starting with the biology, it’s not the complete biology. So, when you take a look at their results, and let’s remember, these are Phase 2b results. They’re still waiting on their later results. There’s nothing that really stands out from our perspective. Efficacy looks fine. The conjunctivitis looks similar to Dupixent. I think some of the big differences are is that we’re six years ahead at that point by the time they launched. We are a mega blockbuster. We’ve become the standard of care. So, I think for somebody to come in with something that isn’t so much to offer, I think that that is -- regardless of your experience in a therapeutic area, it’s not therapeutic experience in atopic dermatitis. So, as we said, it’s part of the story. IL-13 is certainly not the full. We’ve got the best profile.
Paul Hudson
Yes. Thanks, Bill. Sorry, was there a follow-on? Okay. Yes, for it’s great that they have experience with Taltz. I have a lot of experience with Cosentyx, and nobody’s got the experience that we have in AD. And I’m telling you, what the team has done with Dupixent is incredible. We never underestimate competition, particularly well-organized ones. But it starts with the biology, like Bill said. And if you’ve got half the answer, you have a long road to hoe. I’m sure they’ll make some progress. But let’s go all the way back to the fundamental, which is additional weight in the market to help educate and improve penetration is welcome. And if we have the best profile, which we believe we do, then we will disproportionately benefit from that. So, we look forward to the meeting in March where we’ll update you in more deeply about our forecast and indeed, our immunology pipeline in general.
Operator
Yes. Next question comes from Mark Purcell at the Morgan Stanley.
Mark Purcell
Two questions. Firstly, on Dupixent. Could you give us an update in terms of where you are in terms of advanced therapy penetration rates in AD versus the 25% to 30% you just gave? And also some idea of an indication split? But ahead of the 29th of March, just to sort of get us in the mood, perhaps you could help us understand sort of where you believe in the future a U.S., ex-U.S. split could be? Obviously, ex-U.S. growing 80% from a lower base than the U.S., but where eventually do you feel ex-U.S., U.S. split could be? And then, the second one on THOR-707 or SAR’245, the IL-2 Phase 3 go/no-go decisions coming up in the second half of this year. I wonder if you could help us understand which indications and lines of therapy those decisions will be made on, if it’s monotherapy or combination therapy. And what are the gating decisions when making that hurdle into Phase 3?
Paul Hudson
Okay. Thank you, Mark. Bill, I think the question is where are we now and what is the penetration -- how does it evolve towards that 20% to 30% you’re talking about?
Bill Sibold
Yes. So, thanks for the question. We’ve got still a long way to go. Just to give you a sense, in U.S. adult, AD at 7.9%. And when I say the finish lines looking at 25%, 30%, which is a little bit -- it is in the range of psoriasis, maybe a little bit higher. We’ve got a long way to go. So, just reinforcing what Paul and we’ve said along the way, new competitors in the marketplace help to accelerate that. Regarding U.S., ex-U.S., we have seen kind of similar patterns in every market that we’ve launched in the world following the U.S. from a growth perspective. We continue to see that. We expect that. We’re not going to comment on what we think the ultimate geographic distribution will be or indication split.
Paul Hudson
Yes. Thanks, Bill. I think as well, as Europe always takes -- the rest of the world takes some time to get through the reimbursement cycles. And so it always starts slower, then it always gets more interesting. And then everybody always starts to ask questions about it and Bill, we don’t need to share the relative proportions. But, the fact that the rest of the world will just get stronger and stronger in terms of its contribution because the medicine is so good, and I think Bill mentioned China earlier. That is quite a -- 30,000 patients in just months I think starts to help you understand where we might be heading. John, SAR’245 or formally known as THOR-707? Likely indication split? And thoughts on I think it was combos?
John Reed
Yes. Thanks for the question. Maybe before I jump into SAR’245, though, since you brought up the immunology event coming in March, we’re really looking forward to not only talking about Dupixent, but also the broader portfolio. We’ve grown from just 6 molecules in development for immunology to now 17. And so, you’ll be hearing about our biologics that include amlitelimab, the OX40-Ligand, itepekimab, the IL-33 antibody in development for COPD, our engineered interleukin 2. On the other -- flip side of the story, THOR-809, that stimulates regulatory T cells instead of effector T cells; our bispecific multispecfic nanobodies that do nifty things like neutralizing both TNF and IL-23 in a single molecule; a new concept for inflammatory bowel disease; CD40-Ligand, et cetera; as well as our oral small molecule portfolio of rilzabrutinib, a unique BTK inhibitor; our RIP kinase inhibitor; our oral TNF inhibitor; and the IRAK4 degrader. So that portfolio for immunology has really blossomed, and we look forward to talking more about that in March. Now, the SAR’245, we have a large platform study underway in lung, head and neck, GI, skin and lymphoma. And like most companies, we sort of started with the obvious, to do combinations with PD-1, and we’re pursuing that. But this year, we will be embarking on novel combos with other kinds of mechanisms. I would note, for example, that we have three T cell engagers now in development. We have our first NK cell engager went into development. We have our universal allogeneic NK cell platform. So, there’s a lot to think about as combination opportunities with SAR’245 across a range of solid tumors and hematologic malignancies. This will be a rich year for generating those early data signals. We’re eagerly anticipating what we might be able to do with this best-in-class engineered version of interleukin 2.
Paul Hudson
Thanks, John. I do think -- and I talked about it actually quite recently, the number of signals that we’re going to get across the pipeline, but particularly in oncology, is going to be quite interesting this year. While we know they’re only early for some of you for -- but we would like to be an emerging player in oncology, there will be nice moments for us to make some decisions about which way to go, and we’re optimistic. Next question, please?
Operator
Next question would be from Emmanuel Papadakis at Deutsche Bank.
Emmanuel Papadakis
Perhaps I could give one quick one on efanesoctocog, just your expectations or your ambitions perhaps for the upcoming pivotal data. I think you said you’re hoping to show above near normal expression above 40% factor rate in four days. What sort of figures would you be hoping to be showing at seven days? And what kind of share implications do you think that could have relative to what Elocta has at present? Indeed, if you could give us some color on where you think Elocta is presently, that would be helpful as well. And then, perhaps a second question on the SHP2 KRAS, given the decision to progress the combination to Phase 2 with Amgen. Just wondering if you’ve see any data that provide confidence on synergy for that combination given the pretty clear lack of SHP2 monotherapy activity and the timing of that potentially either Phase 1 or data from the ongoing Phase 2 being presented to us at a scientific conference, that would be helpful.
Paul Hudson
Thank you, Emmanuel. John, let’s -- I’ll come to you in a moment. But Bill, I don’t know if have any comment on that? Actually, John may have, too, as well on efanesoctocog. I don’t think we’ve declared what our expectation is. But certainly, our profile is going to be best in class. So Bill, do you want to comment?
Bill Sibold
Yes. I think that’s right. I think if you take a look at what we showed in the Phase 2, which showed that over half the week, four days, where you’re at essentially a near normal level. And by the end of the week, it tapers off to in the 10%, I believe.
John Reed
Yes, but still quite a -- quite strong protection even at the end of the week.
Bill Sibold
Yes. I mean this -- you just look on the slide that I showed, no one’s even close to that. And no one is even close to that with a once weekly. So, this, we consider, really transformative in the hemophilia A space. When you think about patients, kids who want to have an active lifestyle. And if you can give them something they’ve never seen before, then maybe for just a brief moment, normal, and you do that for the better part of the week, you begin to think about giving them a little bit more of their life back, and being active and so forth. So, we’re really excited. That’s what -- we expect to see that in our Phase 3 release. We hope that’s -- it set a pretty high bar -- set a high bar for us, set a high bar for the market, I think, overall. So, stay tuned, more to come on that one. But this is really something which is different. No one’s been able to offer this before. So, I think now we’re hearing patient communities really excited.
Paul Hudson
Yes. And now, it’s -- I’ve heard that, too, obviously, Bill. And I think, the real question is, could it go even longer depending on which -- the patients longer term. I mean it gets very exciting for efanesoctocog and our confidence is building. And as you know, the gene therapy, at least this generation doesn’t seem to be definitive. And of course, Hemlibra comes more towards the weekly or biweekly itself. Then the opportunity is perhaps even bigger than we thought when we started on this journey, I’ll be honest. And of course, half the market is still impacted, like Bill said. So it will quite interesting for us. John, maybe shift to KRAS?
John Reed
Yes. So, the reason that we’re pursuing that combination is because in preclinical studies where we and others tried different combinations of SHP2 with various other signal transaction-blocking molecules. That was always consistently the place where we saw the best combination from efficacy. So, the most synergy. And again, this is not just Sanofi data, but it’s Mirati data, it’s Amgen data, et cetera. So, we think that if there’s a combination where SHP2 can shine, this is it, and we’re doing the studies this year. It’s another one of these where the signals will be the important determinant of what kind of trajectory we can take with that mechanism. So, that’s the rationale and the data will ultimately speak for themselves, and we’ll be gathering it this year.
Paul Hudson
Thanks, John. And maybe, Emmanuel, I’ll just thank you for the bit of research you did on Rezurock. I find it really interesting how physicians were really thinking -- confident already and thinking about moving to earlier lines. I mean, of course, it’s just a survey. But it was very insightful, and we enjoyed reading that. So, thank you for that work.
Emmanuel Papadakis
You’re welcome. Congratulations on the strong launch.
Paul Hudson
Thank you very much. That means a lot. Okay. Eva? Eva Schaefer-Jansen: Felix, last question, right?
Operator
Yes. Last question would be from Matthew Weston at Credit Suisse. Matthew?
Jo Walton
It’s Jo here. I’m sorry. I had two questions. On Dupi, I wonder, you’ve given us the 8% penetration in the U.S. adult market in AD. Perhaps half of the sales potential comes from other indications. So, I wonder if you could just tell us how successful you’ve been in penetrating things like asthma, so that we can see how broad the appeal of this is beyond atopic dermatitis. And I noted that you’re going to update your sales projections but that’s before you have the COPD data. I thought you were waiting for that before you gave us an update. And my second question would be on efa. So, I would have assumed that if somebody was interested in efficacy, but not so concerned on safety, they may already have moved from a factor to a nonfactor. So, safety is likely to be a very important part in making the decision for these patients to move on to your new product. How much safety data will you have at the time of submission and of launch? And what makes you so confident that people won’t think that the different pharmacodynamics of this factor could impact on the safety characteristics of the product?
Paul Hudson
Okay. We’ll there’s quite a lot in there. Jo, you always keep me guessing. Sometimes, you can’t connect and then you appear as Matthew Weston, so. But either which way, I’m glad that we got to the questions. Dupi in other indications penetration, Bill?
Bill Sibold
Yes. So, if you look, Jo, in asthma, we’re at about 19% biologics penetration. Okay? So, that’s the starting point. And then, as you’ve heard from a -- per specialty perspective, we’re leading in each of the specialists with Dupixent. And the other indications, look, we’re -- it depends again on the bio penetration. They’re pretty low. We’re starting with a brand-new indication, so to speak, with nasal polyps. We’re the only player there. Still working on the epi a little, but it appears as though we’re having good, strong penetration there. I won’t give a number at this time. Regarding -- the second question was about...
Paul Hudson
Well, there’s one about why are we waiting for the COPD data, which I am happy to answer. But then we move to a safety and efficacy trade-off on efanesoctocog, which maybe get to with John. So, Jo, we can’t win. If we wait, you say why are you waiting, and if we don’t wait, you say why are we not waiting. We’re sort of betwixt and between. I think because the COPD data is in ‘23, I think we all felt that a good time to take stock would be towards the end of Q1 and using a deeper immunology catch-up that we think that’s worth doing. And, of course, we won’t be able to declare a new peak without referencing that it’s like it will be different with COPD if the data reads out. How we frame that when -- we’re very early in the thinking. So, stay loose on that until we get there. But I just don’t think, given the run rate and the prescriptions that we could ask people to wait a full year or more, actually, to understand what the peak could be. John, I don’t know if you’ve got at all on the safety efficacy trade-off on what data we’ll have...
John Reed
Yes. I’m a little -- I’d say, I’m a little surprised by the question because this safety of this next-generation Factor VIII is -- it’s pristine. There have been no safety signals. We don’t have any reason, really, to believe there would be any. You could almost say, to some extent that way was paved with products like Eloctate, which fuses an Fc region onto Factor VIII. And here, there are some additional embellishments with the so-called extend technology. But that had also been derisked with other molecules that have been taken in the clinic, including an approved product. So the components of the molecule have all been derisked, and we’ve not seen any safety liabilities. On the other hand, if you think about alternatives, they do have some safety -- historical safety baggage. So, I really think on a safety standpoint, again, we come out best-in-class.
Bill Sibold
Yes. And John, just to add to that. I think clearly, from an efficacy perspective, we win, too. I mean, no one’s -- if you look at the comparison where emicizumab is, if you try to estimate where it is, it’s nowhere near normal, right? It’s nowhere near normal Factor VIII. So, we’re really confident that we win on the safety for -- just redefine the safety bar. And then, if you’re looking at a weekly dose, that’s pretty convenient as well. So, I think across both the parameters, we’re in really good shape.
Paul Hudson
Yes. Thank you. When I joined the Company a lot of people asked questions like did the company not understand Hemlibra was coming when we got into fitusiran in 001? And half the people responsible for Hemlibra work for us now. John Reed, thanks. But, one thing we did learn was that these patients are dynamic and they will move fast. If they see a better choice to be made, particularly if you’re not a true monthly, you’re actually a every 1 to 2 weeks in the case of the nonfactor. Bill said set a new standard. I think the competition needs to be slightly more concerned that the patients are much more likely to change. It’s what got them their position in the first place, and it’s what we’ll do when we launch with efa, which is not that far away. So, thank you for those questions. Thank you to everybody, for the energy and the contribution. I’m delighted, by the way, as always, we’re starting to transition more towards science and the transformation of the Company, a little less just on the basic financials, which every day we’re responsible for, don’t even think that we’re not. But, we think in terms of value creation and in the right to bring our pipeline forward and surprise you is very, very important. Nothing is off the table. We’re reshaping the Company real time. You may not see it and fully, you don’t -- you’re not part of it. But I think as we look back, I like to, particularly at full year, we get to look at the distance traveled just in 12 months. I think it feels like we’ve come an awful long way. And while we got some news flow up ahead of us, and we hope it’s all positive, we will keep moving forward at finding signals and advancing 36 programs that were not moving last year -- sorry, at the beginning of last year, that moved last year, and 10 first in human for the first time in the Company’s history. The penny should be dropping that our ability to pivot on science is really in full flight. So, thank you to everybody and the team. Thank you to everyone. Thanks everybody on the call. Eva Schaefer-Jansen: Thank you very much. You may now disconnect.
