With that, I will turn over the call to Dr. Bourla. Albert, please go ahead.
spk05: Thank you, Chris, and I think there was a problem with your line at the last second, so if you can have a look on that. Welcome to your first FISER earnings call. as our new chief investor relations officer. Hello, everyone. I'm proud to say that Pfizer delivered an outstanding second quarter. Most notably, we delivered extremely strong financial results, even excluding direct lines, even excluding direct sales and alliance revenue provided by our government. We've generated 10% operational revenue growth compared to the prior year quarter. And I would note that the year-ago quarter was also very strong, delivering 6% operational growth for the comparable reason. At the same time, we continue to accelerate the production and delivery of the Pfizer-BioNTech COVID-19 vaccine, and in collaboration with BioNTech, have now shipped more than 1 billion doses since last December. This is truly remarkable, especially when you consider that prior to the pandemic, Pfizer produced approximately 200 million doses annually across our entire vaccines portfolio. Let me start with a commentary on some of our biggest growth drivers in the world. The Pfizer-BioNTech COVID-19 vaccine contributed $7.8 billion in global revenues during the second quarter, and we continue to sign agreements with governments around the world. Just last week, we announced that the U.S. government has purchased an additional 200 million doses of the vaccine bringing the total number of doses to be supplied to the U.S. government under its existing supply agreement to 500 million. This is in addition to the 500 million doses that we agreed to provide to the U.S. government as a non-for-profit price to be donated to the poorest countries in the world. We anticipate that the significant amount of the remaining 2021 vaccine manufacturing capacity will be delivered to middle and low-income countries where we price in line with income levels or at a non-profit price. In fact, we are on track to deliver on our commitment to provide this year more than 1 billion doses, more than 1 billion doses, or approximately 40% of our total production to middle and low-income countries and another $1 billion in 2022. Vintaco and Vintamax revenues were up 77% operationally to $501 million globally. Our disease educational efforts in the U.S. continue to support increases in appropriate diagnosis, while the main driver of growth in Japan has been the successful establishment of several referral networks in select areas, resulting in new patient starts. We anticipate these efforts will continue to support a strong trajectory for the franchise. Eloquence continued its strong performance with revenues up 13% operationally to $1.5 billion. This was led by growth in the U.S. and emerging markets driven primarily by strength of the clinical profile, ease of use for both patients and clinicians, continued increased adoption in non-valvular atrial fibrillation, and overall oral anticoagulant market share gains. Brevnar 13 in the U.S. was up 34% overall to 642 million. This growth was due primarily to higher levels of healthcare activity and wellness visits compared with the prior year quarter, which was heavily impacted by COVID-19-related mobility restrictions and limitations. Growth in the pediatric indication was also due to year-over-year government purchasing patterns and was partially offset by lower year-over-year birth rates. Growth in the adult indication was partially offset by the continued impact of the lower remaining eligible unvaccinated population. During the quarter, the U.S. Food and Drug Administration approved Prevnar 20 for adults ages 18 and over for the prevention of both invasive disease and pneumonia caused by the 20 pneumococcal serotypes in the vaccine. I would note that a 15-valent vaccine also recently received FDA approval in adults. However, that approval did not include the pneumonia indication. We believe the only way to add that indication to the 15-valent vaccine in the U.S. would be to conduct a post-licensure efficacy effectiveness trial which we believe means that for the foreseeable future, Prevnar 20 likely will be the only vaccine with an indication against vaccine-type pneumonia for the 20 serotypes. For Ibrans, we continue to be pleased by the double-digit growth in international markets and are encouraged by signs of recovery in several key markets. In the U.S., Ibrans continues to be the leading CDK4-6 inhibitor with 83% total patient share and 73% share of first-line metastatic new patient starts. While total prescription volume was stable in the second quarter, paid demand for eye brands was down due to increased enrollment in our patient assistant program, which we referenced last quarter. This resulted in a second-quarter revenue decline in the U.S. of 7% compared with a year-ago quarter. In lightest, global revenues were up 29% operationally to $257 million, primarily reflecting increased adoption in the U.S. and developed Europe of combinations of certain immune checkpoint inhibitors and in light. Extending the U.S. was up 14% to $303 million, driven by strong demand across all approved indications. Our global biosimilars revenue grew 88% operationally to $559 million, driven by several recent oncology biosimilar launches. As you can see, biosimilars have become a meaningful part of our business while delivering lower cost patient care options that can help reduce overall healthcare spending levels. Now let me share two brief updates from our JAK inhibitor portfolio. We continue to remain confident in the importance of the JAK inhibitor class, for appropriate patients with inflammatory diseases, given the role of JAK pathways in inflammatory processes. In addition, we have taken a targeted approach to developing selective JAK inhibitors based upon our extensive knowledge of JAK biology, coupled with our medical chemistry capabilities. That suggests the best target for a specific indication. We believe this approach may optimize the benefit-risk profile. Of course, patient safety is of utmost importance, and we continue to monitor all compounds in our portfolio to identify signals, both in development as well as after regulatory approval. Global sales revenue went down 9% operational in the quarter to $286 million, driven primarily by a 15% decline in the U.S. While prescription volume increased 2%, this revenue decline reflects an unfavorable change in tunnel mix toward lower-priced channels, and continued investments to improve formulary positioning and unlock access to additional patients' lives. Also, a negative impact on new patient starts resulting from an ongoing review by the FDA of safety data from the post-marketing oral surveillance study of Zeldens in subjects with rheumatoid arthritis. who were 50 years of age or older and had at least one additional cardiovascular risk factor. International developed markets achieved 11% operational growth in the same quarter. The FDA recently notified Pfizer that it would not meet the Prescription Drug User Fee Act, the PEDUFA goal, date for this supplemental new drug application for Zeldens, Zeldens XR, for the treatment of adults with active ankylosing spondylitis. No revised PDUFA goal date has been set for these NDAs, supplementary NDAs. The FDA also recently notified Pfizer that it would not meet the PDUFA goal date for the new drug application for abracitinib for the treatment of adults and adolescents with moderate to severe atopic dermatitis. The FDA cited its ongoing review of Pfizer's post-marketing safety study. Oral surveillance evaluating tofacitinib in patients with rheumatoid arthritis as a factor in the extension. No revised PEDUFA goal has been set by this NDA, for this NDA. Now I want to touch on the Biden administration's recent executive order on promoting competition. While I believe there may be better alternatives that some of these policies put forward in the executive order, we can agree that fostering competition and lowering costs for patients should be the focus of any regulatory or legislative action. We continue to support more affordable options for patients like biosimilars, improving the Medicare program to cut out-of-pocket costs, and also lower cost sharing for seniors and making insurance work by requiring that patients share in rebate savings at the pharmacy counter. We believe these meaningful solutions would have an immediate impact for patients without sacrificing future innovation. Overall, I believe the second quarter was a clear and powerful demonstration of the capabilities of the new Pfizer Looking forward, we intend to build upon these successes by continuing to follow the science, trust in our people, and remain focused on delivering breakthroughs for the patients we serve. As such, we continue to expect a revenue cager of at least 6% on a risk-adjusted basis through the end of 2025 and double-digit growth on the bottom line. I would note that these projections do not include any potential impact from our COVID-19 vaccine, the recent or subsequent business development activities, or potential future mRNA programs. We remain very confident in our ability to achieve these growth rates because of the strength of both our current product portfolio and our R&D pipeline. At the same time, we will continue to pursue business development opportunities with the potential to further enhance our long-term growth prospects. Just last week, we announced a global collaboration with ARVENAS to develop and commercialize ARV471, an investigational oral product estrogen receptor protein degrader. The estrogen receptor is a well-known disease driver in most breast cancers, and we are excited to work with ARVENAS on the first potential product for breast cancer, which, with its encouraging early clinical data, has the potential to become a novel hormonal therapy backbone for HR-positive breast cancer. Now, I will turn it over to Michael to speak more about our R&D efforts. And then, of course, Fran will provide financial details on the quarter and our outlook for the remainder of 2021. Michael.
spk06: Thank you, Albert. I'm delighted to share some highlights from Pisces R&D Pipeline, which continues to be one of our greatest strengths. Today, I will share updates on eight select programs in which we are pursuing first-in-class breakthrough science and which have estimated approvals before 2030 and the potential to have profound impact on millions of patients. Last week, we announced a global collaboration with Arvinas to develop and commercialize ARV471, potentially the first Protech, or proteolysis targeting Chimera, estrogen receptor protein degrader. 471 represents breakthrough drug design technology. Protech protein degraders efficiently eliminate, rather than inhibit, disease-causing proteins. To our knowledge, 471, which was designed to be an oral, high-potency, estrogen receptor degrader with a favorable safety profile is the only ER-targeting protect degrader in clinical development and has a distinct mechanism action from the many in development. In the future, novel assets like 471 have the potential to be the new endocrine therapy backbone, either alone or in combination with CDK inhibitors, such as Ibran, other targeted therapies, and or therapies with novel mechanism action. Early clinical data show 471 has the potential to be an endocrine therapy of choice across treatment settings in breast cancer. 471 is being evaluated as a treatment for metastatic breast cancer in a Phase I dose escalation study, a Phase Ib combination study with IBRAMS, and a Phase II monotherapy dose expansion study. Starting in 2022, we expect to initiate phase three studies across lines of therapy in metastatic breast cancer, including in combination with IBRANS, followed by pivotal studies in the early breast cancer setting. Let me share some of the preclinical data that has us excited. The chart on the left shows 471 demonstrated impressive anti-tumor activity in combination with IBRANS in preclinical studies. In the Phase I interim analysis of 21 patients, 471 demonstrated a compelling efficacy signal in heavily pre-treated patients, the majority with prior fulvestrin treatment and all with prior CDK46 inhibition treatment. The images on the right show one patient on 471 monotherapy who had a confirmed partial response after four cycles with a 51% reduction in target lesion size as indicated by the arrows. Two patients had unconfirmed partial responses and one patient demonstrated stable disease with more than 50% target lesion shrinkage. Five paired tumor biopsies demonstrated ER degradation up to 90% with an average of 62%. The next program is Robo2, details of which we have not shared previously. No disease-specific treatments are currently available for focal segmental glomerulosclerosis, or FSGOS for short. We have developed, in collaboration with Boston University and Boston Medical Center, a potentially novel and first-in-class disease-modifying biological therapy comprising a SLP2 ligand antibody FC trap that lowers activation of the Robo2 receptor for treating FSGS, as well as adjacent renal glomerulopathies. Preliminary results from interim analysis of our ongoing PACE2A study in adult patients with steroid-resistant FSGS demonstrated promising data with a statistically significant and clinically meaningful reduction in urine protein to creatinine ratio, or UPCR. We are advancing the program to potentially demonstrate proof of concept in 2022 and preparing for pivotal studies. This chart shows the change in UPCR, a marker of renal function, from baseline in steroid treatment resistant patients in the Phase IIa study. There was a favorable reduction in proteinuria at 13 weeks based on data from approximately half of the first dose cohort of the study. Please note, after stopping the treatment as per study protocol, the UPCR deteriorated, indicating the need for continuous therapy. Treatment every two weeks was well tolerated with no significant safety signals today. Next, let's turn to our gene therapy programs in hemophilia A and B and Duchenne muscular dystrophy. Pfizer continues to advance the broadest late-stage gene therapy portfolio of potentially transformational treatment. We expect phase three interim analysis for all three programs in 22. In a phase one-two hemophilia A study, we have seen durable expression of factor VIII through 78 weeks with an annual bleed rate in the first 52 weeks of zero. In a phase I-II hemophilia B study, we have seen sustained expression of factor IX activity into year four of the phase I-II long-term follow-up study with an annual bleed rate of less than one. in a phase 1B Duchenne muscular dystrophy study, statistically significant expression of mini dystrophin, and a 3.5 point increase in the North Star ambulatory assessment score have been observed. Now, we'll turn to our Lyme disease vaccine, the only active Lyme vaccine candidate in clinical development today, being co-developed with Valneva. The ongoing phase two study, which completed recruitment of adult and pediatric participants last week, will evaluate the optimal vaccination schedule for use in phase three. We expect potential proof of concept in January 22, and a phase three study in the first half of 22. This chart shows that more than 90% of subjects seroconverted to all six serotypes with a three-dose vaccination schedule at 0, 2, and 6 months in the Phase 2b study, demonstrating a favorable immune response. Our respiratory syncytial virus vaccine is the most advanced bivalent protein-based vaccine with Phase 2 data published showing high neutralization types against both or the A and B subtypes. which has not been demonstrated in clinical development by a monovalent pre-fusion F vaccine. We have been advancing this asset for both adults through direct vaccination and infants through maternal immunization. Today, I will focus on adults. In 2020, we initiated a phase IIa study to evaluate the safety, immunicity, and efficacy of the recombinant RSV pre-fusion vaccine in a virus challenge model in healthy adults 18 to 50 years of age. I will show you data on the next slide, which we plan to submit for peer-reviewed publication soon. Results from a phase two challenge study of 62 subjects showed a vaccine was 100% effective against mild to moderate symptomatic infection, and most participants in the study experienced minimal to no side effects. As a performance benchmark, the AD26-RSV-PF vaccine showed 52% observed efficacy in the same human challenge model. In this slide, we show very stable protective changes of the vaccine on viral load, left side, and in reducing drastically RSV disease severity, right side. Based on these overwhelmingly positive data, We will accelerate the development of our RSV vaccine in adults. We plan to initiate a global phase three trial in the third quarter and hope to conclude the study swiftly in part due to the recent spike in RSV infection reported by CDC. The swift delivery of the world's first mRNA-based vaccine made the scientific opportunity of mRNA technology clear. Our strategy to advance and unlock the full potential of mRNA is focused in three core areas. We're strengthening the core COVID-19 vaccine franchise, growing an infectious disease vaccine pipeline, and exploring therapeutic areas like rare disease and oncology with the strongest potential. Let's start with the mRNA flu vaccine, which we began working on with BioNTech in 2018. Having a flu vaccine with much better efficacy, better T-cell and innate immune responses, and more timely manufacture soon after strains are known could dramatically change trajectory of disease. We are projected to start first human trials for a modified RNA or mRNA flu vaccine in the third quarter subject to regulatory approval. Preclinical studies were performed with a first-generation modified mRNA tetravalent flu vaccine, and the data were compared to data from a marketed flu ad vaccine. Immunogenicity mice for a first-generation mRNA flu candidate across the 2018-19 northern hemisphere strain were higher or as high as the trivalent adjuvanted subunit vaccine. We are encouraged by these data and look forward to progressing these programs. We now turn to our COVID-19 vaccine program in collaboration with BioNTech. The Delta variant, which is the most transmissible we have yet seen, is expanding rapidly worldwide and now represents approximately 83% of sequence cases in the US. We continue to believe it is likely that the third dose booster may be needed within six to 12 months after full vaccination, to maintain the highest level of protection. And studies are underway to evaluate the safety and immunity of a third dose. We are in ongoing discussion with regulatory agencies regarding a potential third dose booster of current vaccine and assuming positive results, anticipate an emergency use authorization submission as early as August, pending regulatory approval We also plan to start an immunogenicity safety study in August to evaluate an updated version of our vaccine specifically designed to target the Delta variant. Here we show initial data from a small number of patients receiving a third dose of the existing vaccine. We observe a significant boost in utilizing antibodies following a third dose of the current vaccine for both wild type and the beta variant. At eight months post-dose two, antibody levels start to decline from earlier peak. In our initial analysis, a third dose given more than six months after the second dose elicited neutralizing antibodies, which are more than five times higher than the wild type and more than 10 times higher against the beta variant than after two primary doses. The third dose elevates the neutralizing antibodies in our laboratory studies up to 100 times higher levels, positive three compared to pre-dose three. Just as we saw in the analysis of neutralizing antibodies from those in the original phase three trials, the levels in the older population were comparable to the younger population. Here we show new breaking data from a small number of participants that the third dose boost with the current vaccine elicited neutralizing titers that when tested against the Delta variant were more than five-fold post-dose two in younger people and more than 11-fold post-dose two in older people. Receiving a third dose more than six months after vaccination, when protection may be beginning to wane, was estimated to potentially boost denaturalizing antibody titers in participants in this study to up 200 times higher post-dose 3 compared to pre-dose 3. These preliminary data are very encouraging as Delta continues to spread. Finally, let's turn to our potentially first-in-class COVID-19 antiviral protease inhibitor. If successful, our protease inhibitor has the potential potential to provide patients infected with COVID-19 with a new oral therapy that could be prescribed for a five-day treatment course at the first sign of infection before patients are hospitalized or in critical care. For patients who are in close contact with someone who contracts COVID-19, we will study both five- and ten-day post-exposure prophylaxis courses. The goal is to reduce SARS-CoV-2 viral load, thereby hopefully decreasing or preventing symptoms of COVID-19 and minimizing the risk of hospitalization. In July, we initiated a phase two suite trial to evaluate efficacy, safety, and tolerability of the orally-administrated protease inhibitors in participants with COVID-19. If successful, we project a potential U.S. emergency use authorization submission in the fourth quarter. Our protease inhibitor exhibits potent selective in vitro antiviral activity against SARS-CoV-2 and other coronaviruses and potentially all currently known COVID-19 variants. It also has demonstrated a robust preclinical antiviral effect on cells and in SARS-CoV-2 infected animals, enabled by selectivity that is more than 100 times higher for coronavirus real proteases than human proteases. The chart on the left shows robust dose-dependent reductions in disease microscopical scores in mice. In phase one human studies today, we have seen desirable drug exposure, good tolerability, and no safety findings, up to a dose of 500 milligrams twice a day over 10 days in healthy volunteers. The chart on the right of the phase one pharmacokinetic study shows high drug exposure over the entire treatment period, exceeding greater than five times the exposure predicted to inhibit SARS-CoV-2 viral replication. This concludes our review of eight selected breakthrough programs. among many more to come this decade. Now, let me turn it over to Frank.
spk14: Thanks, Michael. I know you've seen our release, so let me provide a few highlights regarding the financials. The COVID-19 vaccine again had a dramatic positive impact on our quarterly results, and Albert has already addressed the key points on the COVID-19 landscape. Looking at the income statement, revenue and adjusted cost of sales was significantly impacted by COVID-19 vaccine sales and the associated 50% gross profit split with BioNTech, which we recognize on the cost of sales line. Revenue increased 86% operationally in the second quarter of 2021, driven by COVID-19 vaccine sales and solid performance from a number of our other key growth drivers. And looking at the revenue growth excluding the COVID-19 vaccine contribution from direct sales and alliance revenues, I want to reiterate what Albert said in that we saw a continuation of solid performance from the business again this quarter, delivering 10% operational growth despite a negative 4% impact from price. This nicely supports our projected revenue CAGR of at least 6% through the end of 2025. Of course, there will be some variability in quarterly growth rates due to a variety of factors, but we continue to expect at least 6% through 2025. There was no impact from the number of selling days in the quarter as compared to the year-ago period, like we saw in our first quarter where we had more selling days compared to the year-ago period. I'd remind you that the offset to this imbalance will be seen in the fourth quarter results where we have fewer selling days as compared to the year-ago quarter. For the full year, this results in essentially the same number of selling days in 2021 as 2020. The adjusted cost of sales increase shown here reduced this quarter's gross margin by 19 percentage points compared to the second quarter of 2020 which primarily reflects the impact of the COVID-19 vaccine, gross profit split, and applicable royalty expenses in addition to much smaller impacts from foreign exchange product mix. Adjusted SINA expenses increased owing to a more normalized level of promotional and sales force activity, along with some impact from foreign exchange. The increase in adjusted R&D expense this quarter was driven by increased investments in the COVID-19 vaccine and antiviral programs as well as other programs within our pipeline. Given the tax effect of increased COVID-19 vaccine revenue, our tax rate, which will impact our guidance, which I will speak to in a minute. Reported diluted EPS for the quarter was up 58% compared to the year-ago quarter, while adjusted diluted EPS grew 73% for the quarter. Foreign exchange movements resulted in a 6% benefit to revenue as well as a 6% benefit or 3 cents to adjust the diluted EPS. Now let's move to our revised 2021 guidance. We've again provided total company guidance, which includes the business with the COVID-19 vaccine. And then we've provided some additional sub-legit detail on our assumptions regarding the projected COVID-19 vaccine contribution. So you can also see our projection for the business without the COVID-19 vaccine. Our revenue projection has increased, and we now expect it to be in a range of 78 to 80 billion, with the COVID-19 vaccine revenue for the year being projected to be approximately 33.5 billion, based on contracts signed through mid-July. I note that this projection does not include the doses with our contract with the U.S. government announced last week. For adjusted cost of sales, the range has increased to between 39 to 40 percent, which incorporates the incremental anticipated COVID-19 vaccine revenue, which has a significantly higher cost of sales due to the gross profit split with BioNTech as compared to the rest of the business. The projected COVID-19 vaccine revenue as percentage of total company revenue at the midpoints has increased to 42% as compared to 36% in our previous 2021 guidance. On adjusted SINA, we have made a small increase to the projection now expect 11.5 to 12.5 billion. In addition, we increased our adjusted R&D guidance range to 10 to 10.5 billion to incorporate anticipated spending on incremental COVID-19 related programs and other mRNA-based projects that are not part of the BioNTech collaboration. Given the tax effect of increased COVID-19 vaccine revenues, we are increasing our projected tax rate for the full year to approximately 16%. This yields an increased adjusted diluted EPS range of $3.95 to $4.05, or 77% growth at the midpoint compared to 2020, including an expected 4% benefit from foreign exchange. Let me quickly remind you of some assumptions and context on the projected COVID-19 vaccine contribution and our collaboration agreement. As discussed earlier, the Pfizer-BioNTech COVID-19 vaccine collaboration construct is a 50-50 gross profit split. Pfizer books the vast majority of the global collaboration revenue, except for Germany and Turkey, where we receive a profit share from BioNTech, and we do not participate in the China region. We now expect that we can manufacture up to 3 billion doses in 2021, subject to continuous process improvements, expansion of current facilities, and adding new suppliers and contract manufacturers. As of mid-July, we have contracted for approximately 2.1 billion vaccine doses for delivery in 2021, which drove our projection of approximately 33.5 billion in revenue for the year. Our cost of sales for the COVID-19 vaccine revenue continues to include manufacturing and distribution costs, applicable royalty expense, as well as a payment to BioNTech representing the 50% gross profit split. We continue to expect that the adjusted income before tax margin to the COVID-19 vaccine contribution to be in the high 20s as a percentage of revenue. This margin level also includes the anticipated spending on additional mRNA programs. Let me add that if we contract for delivery of additional doses during the year, we will provide a guidance update in our subsequent earning releases. If we remove the projected COVID-19 vaccine contribution from both periods, you will see that we slightly increased the 2021 revenue range to 45 to 47 billion representing approximately 7% operational revenue growth at the midpoint. In terms of adjusted diluted EPS, without the contribution from the COVID-19 vaccine, we have increased the range to be between 255 and 265 for the year, which represents approximately 11% operational growth at the midpoint. These growth rates are all consistent with how we've been publicly positioning the business post the Upjohn separation. Going forward, we will continue to maintain a prudent stance toward our capital allocation activities with the opportunities for deployment shown here on this slide. In summary, a strong quarter and first half of the year, and we have increased our revenue and EPS guidance for the remainder of the year. In addition, we've had pipeline advances and just completed a very promising business development agreement with Arvinas. I'll now turn it over to Chris to start the Q&A session.
spk02: Thank you, Frank. Operator, if we could have the first question, please.
spk17: Ladies and gentlemen, if you would like to ask a question, please press star 1 on your telephone keypad. Your first question comes from the line of Carrie Holford from Barenburg.
spk00: Thank you. A few questions on the COVID vaccine, please. Firstly, a point of clarification, can I just check the upgraded 2021 sales guidance for the vaccine reflects only the doses you expect to deliver this year and not for those contracted for delivery in 2022. As you stand today, can you talk directionally about how you see 2022 COVID vaccine sales relative to this new guidance figure for 2021? Do the more recent dose orders you've secured require delivery of the new updated version of vaccine you reference that covers the Delta variant? And then finally, can we assume the price per dose in the most recent order from the U.S. government is equivalent to prior U.S. orders? And how does that pricing compare in the ex-U.S. contracts that you've more recently signed? Thank you.
spk05: Thank you very much, Kerry. Maybe I can give you an answer to that. As Frank said in his remarks in 2021, we provided guidance for approximately 2.1 billion doses. These are confirmed orders, contract time. We have said repeatedly that we expect to have 3 billion doses manufacturing this year. And we are, of course, discussing about those doses, and most of them are in very advanced discussions. So I believe that we will eventually allocate all doses. Now keep in mind that in the second half, as we said, the very big number of doses will go to middle-income countries where the price is very, very different, almost half, and to low-income countries and lower and low-middle level countries where we provide the doses on a not-for-profit basis. So you need to take that into consideration. The second thing that you need to take into consideration is that our financial calendar is not the exact like the political calendar, which means that December sales will not be going to 2021 if it is international. It's going to go to 2022. This is how our financial calendar works. Only the US sales of December will be accounted in this year and will be significant number of doses that will be allocated in December as part of the 3 billion doses. How the 2022 looks like? It's very early to speak. We have multiple countries that they have already accomplished agreements for 2022 and 2023, like Europe, for example, Israel, Canada, Canada, actually, they have also, they go all the way to 2024. US just got an additional 200 million doses. And virtually every country in the world right now is discussing with us for additional doses. Our total expected capacity for 2022, it is four billion doses. And I believe given the needs, that likely will be allocated to the entire world. Then you asked a question about the Delta variant, and maybe I will ask Michael to provide a view on that.
spk06: Thank you, Albert. As you noted in the presentation, all data right now point to that the current vaccine is highly effective against Delta variant. There may be waning over time as often is seen with the vaccine. And that's why we shared today that if you do give a third dose boost of the current vaccine, you seem to regain very high utilizing antibody against Delta. We are also producing a Delta variant specific vaccine, mainly to make sure we cover all options of the future, but we remain highly confident in that the current vaccine, when used appropriately, will be effective against Delta, and we are in dialogues with regulatory agencies about this potential of a third dose of a vaccine pending epidemiology of the vaccinated over time. Thank you.
spk05: Thank you very much, Michael. And they carry also on the price per dose. We do not discuss prices with each individual country, but we have given our overall policy, which says that the high-income countries, they have comparable prices. but they vary only based on we give discounts to these prices based on the volumes that are committed. Middle-income countries, they have approximately half of that price, and for the lower, middle, and low-income countries, we are providing our vaccines at an on-for-profit basis. Thank you.
spk02: Thank you, Albert. Next question, please, operator. Oh, sorry.
spk17: Your next question comes from Matthew Harrison from Morgan Stanley.
spk10: Great. Good morning. Thanks for taking the questions, a few, if I may. First, on the regulatory outlook for the JAK, do you have any idea on how long the FDA may continue to review the file or when we might expect to see some response on next steps there? And then second, on the mRNA flu vaccine, can you comment on the potential regulatory picture there? Do you think you may be able to get that approved just based on titers, or do you think you'll have to actually run a head-to-head study versus the existing flu vaccines? Thanks very much.
spk05: Michael, I think you could take those two questions, and then if Angela wants to add something on the next.
spk06: Yeah, thank you. Well, as you know, FDA and other agencies are reviewing both existing and new JAKs. In FDA, we are waiting for them to conclude final assessment of the Cellion study. And during that period, they have passed PDUFA timeline for both us and other that have developed new JAK. We certainly hope as the workload from COVID may attenuate that the agency will have soon been able to review all available data as we do consider that JAKs have a really meaningful and important role in management of RA properly used in the right patients and also new indications where there are fewer alternatives such as atopic dermatitis, alopecia, vitiligo, and so on. So we cannot give any firm timelines, but we certainly hope it will be relatively soon. For the mRNA flu vaccines, we plan to start our first in human studies shortly based on some of the encouraging data we showed from preclinical studies. We will both run immunogenicity study as well as head-to-head study. Given the high potency of the mRNA, we are optimistic and we believe there is a good opportunity that one can create a premier vaccine with superior efficacy versus existing flu vaccine. That's why we think not only to demonstrate high titers, but also demonstrate superior efficacy would be very valuable, and we are gearing up using all our experience to run trials fast to look at the time schedule for both immunicity and head-to-head event trials.
spk05: Angelo, do you have anything to add?
spk13: I think Michael covered all the key points, you know, just to reassure everyone that we are in constant communication with the FDA. And, you know, they're just doing their risk-benefit analysis as they would with any and all molecules. And so we're very confident that there is a role that our JAKs do play. And we just, you know, we're waiting eagerly for the response from the FDA. So thank you. Thank you.
spk02: Go ahead with the next question, please.
spk17: Your next question comes from Daniel Busby from RBC Capital.
spk09: Hi, thanks for the questions. I've got two. First, on the COVID-19 vaccine, I think it's fair to say that Pfizer has been a bit more outspoken about the likely need for recurring booster doses than CDC and FDA, at least at this point in time. Can you provide any additional color about why that's the case? Is this simply a matter of letting the data catch up to what you view as a likely eventuality, or is it a function of Pfizer and regulatory agencies interpreting the data that we have today perhaps differently? And second, with respect to Previn R20, can you talk a little bit about your expectations for October's ACIP meeting and what you would characterize as a good outcome for the adult use vote?
spk05: Maybe I can give you the answer to the COVID and then Angela can take the problem to Andy. I don't think that there is different interpretation of data between us and regulatory authorities around the world, actually. There is extremely good collaboration and the same interpretation. I think what we have said is not new. For months I'm saying that we believe based on the data that we have seen. holistically, but we will need a booster eight to 12 months from the second dose. And we have seen that with the Delta, that might be needed a little bit earlier, particularly for some parts of the population. But we haven't submitted the data yet. So I don't think that FDA or CDC can speak because they have very different authority when they speak. It's extremely, they have very different considerations. So we will submit those data by August 16. They are aware of them, and the FDA needs to review them and then provide or not their approval. And then once it is approved, the third dose booster, then CDC needs to understand the situation in the country at that particular period of time, and they will have to make a recommendation about the booster. So the same happens in different countries, and depends on what percentage of the population have been vaccinated earlier in the year or later in the year, they may have very different sense of urgency. Clearly, countries that they did big percentage of their population in the January, February timeframe, they have very different urgency because the time is, the clock is ticking. And with that, I will go to Angela about the PREVNR20 and ACIP.
spk13: Yeah, thanks, Albert. Well, you know, you heard Albert talk about the, you know, the very differentiated label that we do have with PREVNR20 in his opening comments. And just to reinforce that, you know, the 20 serotypes and the coverage that, the broad coverage that provides, but also, The fact that our label contains an indication for both IPD as well as pneumonia is really unique. And I think that this pneumonia indication, you know, is a true strength of the Prevnar family, being that we're the only company that has the 80,000-capital trial where this pneumonia indication was based. And so with this, what we anticipate coming up in October are policy questions that will be addressed for both PCV20 as well as the MERC15. And we have an early read into this already because at the last ACIP meeting, different policy questions were posed for both products. For Prevnar20, there's a question around vaccinations of 65 plus as well as 50 plus. in addition to the 18 to 49 or 18 to 59 immunocompromised. For MERC 15, the age range and the policy question posed there was for 65 plus. So when you look at what's different, the only PREVNR 20 was being looked at for the 50 plus. So we'll have to see how all this ends up, and we're looking forward to having a robust discussion at the October ACIP. But I think that the setup of these policy questions give us a good view into what the discussions will look like and what the outcomes might be. So thanks for the question.
spk02: Thank you, Angela. Next question, please, operator.
spk17: Your next question comes from Chris Schott from JP Morgan.
spk03: Great. Thanks so much for the questions. Just coming back to the COVID-19 booster, would you envision this as an annual booster? Or with these levels of antibody titers, would you envision that third dose could give more sustained protection against COVID? I was thinking about just kind of how the market evolves over time. And then my second question was just coming back to the Jax and just two more detailed questions. First, any change in thinking as we think about abracitinib the 100 milligram versus the 100 and 200 milligram approvals. I don't know if there's anything you've learned with regulatory interactions, et cetera, that's changed your view there. And then maybe second question on the JAX is just with Zelle Jans, what would an EMEA-like label revision mean for Zelle Jans as we think about the U.S. commercial opportunity? Thanks so much. Yes.
spk05: Michael, I think you can take the booster in terms of is it a third dose and done, you think, or is it going to be an annual revaccination? And then, Angela, we move to you for Jackson's evidence.
spk06: Thank you. Well, Albert spoke earlier to the importance of both following vaccine efficacy in different regions of the world and entry of new strains. Right now, we have a surge in the Delta strain. It's the most infectious strain ever seen, and it puts pressure on vaccinated individuals. The data we showed today indicate at six to eight months, we can boost up to 100-fold the antibody titer after the dose compared to pre-dose. At the same time, we hear reports from various parts of the world, real world evidence that they do see some breakthrough cases of the Delta variant in vaccinated. So this type of data is a typical package we will put together, in this case for August submission, as Albert alluded to, for a third dose. We will continue to monitor and generate data on the impact of a third dose, which we do have ongoing in phase three, and possibly soon also in real-world evidence. We expect the third dose to be potent and somewhat maybe more long-lasting than the second, but we also recognize that the virus constantly evolves and you all start to notice about delta plus variant. Hence, while I cannot predict with certainty the future, I would not be surprised if similar to flu that we would need with interval to boost our vaccine against COVID. Whether this will be on an annual or based on simple diagnostic that allow it to be boost at the right time before you risk for infecting inside, we need to monitor. But all in all, we believe that similar to a flu business, it may be likely for the COVID business, but we are gathering data to validate and we'll constantly work with key opinion leaders and regulators in interpreting the data.
spk05: Angela?
spk13: Great, I'll start with Abro. The conversations and the discussions that we're having with the FDA as it pertains to Abro have been consistent. And at this point, as we've discussed earlier, we're just waiting to hear from them as to their points of view. But both doses are still in discussion. And I think, you know, ultimately, I think ultimately where you might be going with your question is sort of what happens if we only get one or the other. And I just want to reinforce that we are very confident in the potential of Abro, whether it's for both doses or for one. And the reason is that we come back to just the size of the market. We've discussed this before, but there is a very, very large market with a huge unmet need. There's 60 patients, 12 and up. with atopic dermatitis, only 4 million of those are being treated today with any systemic therapy. And because this is such a heterogeneous disease, you know, patients really need, you know, different options. And so we're really looking forward to hearing back from the FDA, but we believe that the risk-benefit profile of abracitinib is going to have a role in the treatment of atopic dermatitis patients and it will be a welcomed addition and an additional option that patients really need. And then coming back to Zeljans, you had a question around our EU label. So actually, the changes to the EU label were posted in June, although we're still waiting for the final SPMC, SNPC, excuse me. And there, the label is really looking at a cautionary note for those who are 65 plus who are smokers or have malignancy risk. And the caution there is for physicians to consider alternative therapies prior to using Zeljanz. And so I think this is pretty consistent with how Zeljanz is being used today. If you look at where the utilization is, more than half of our business is in third-line treatment, which is after the utilization of other treatments like biologics. So again, I think we'll wait to see how this plays out, but the fact that it is being recommended for third-line is very consistent with how it's being used today.
spk02: Thank you. Sylvia, next question, please.
spk17: Your next question comes from Ronnie Gale from Bernstein.
spk12: Good morning and thank you for taking my questions. The first one will also be in the boosters. I fully understand this point around the third dose increasing antibody significantly. The counterpoint that has been raised is that the third dose is not needed because while antibodies wane, immunity against severe disease is not, or at least have not so far waned over time. Can you discuss a little bit how you see the weighting of immunity in the large public and the elderly as you're seeing it for your vaccine even if antibody dose comes down? The second question is around biosimilar business. This is something you highlighted. We're not really seeing a lot in the pipeline or the clinically available pipeline for your biosimilar business beyond the Humira biosimilars. Can you discuss your plans for that business? Is this still the emphasis for Faizo, are you deemphasizing that?
spk05: Thank you, Ron. Michael, again, I think I will ask you to make comments on if we see waning of immunity also in severe disease or in hospitalizations. And we have seen data about that. Michael?
spk06: Yeah. Thank you, Albert. It's a very good question. So first, We do see more, after six to eight months, more rapid waning concerning infections and mild to moderate symptoms. Those are likely entirely or to a large degree dependent on antibodies, and the drop in titer that we alluded to, if you raise it, may have a good probability to reverse that waning. the protection against severe disease, hospitalization, and fatal outcomes remains pretty high, but we do see some lowering, particularly in real-world evidence studies from Israel, we see some lowering in that protection in risk groups such as older adults immunocompromised. That's likely because in addition to antibodies, T cells help out in keeping up strong defense against severe disease, which is later in the infection process, and particularly when antibodies have waned. But the slow but still noticeable gradual decline in protection also against severe disease is something that's on our eyes. And certainly, we believe that by boosting, you may strengthen antibodies and T cells. And you have an early warning signals whether to do that with some modest waning in hospitalization given its risk of severe outcome or wait in your interpretation of that. All in all, I think a third would strongly improve protection against infection, mild-moderate disease, and reduce the spread of the virus, but also give you some extra muscle and reverse the slower decline against severe disease. So this is how we're looking at it from multiple angles in order to describe the full opportunity with boost.
spk05: Thank you, Michael. Angela?
spk13: Thanks for the question on the biosims, and certainly we've been so pleased with the tremendous growth that we've seen in this area and the deep utilization of our biosim. I will say that for our biosimilar portfolio and where we see it today, since we've made this pivot, to a pure play sort of innovation focus in our pipeline, we are really now looking at that by a similar portfolio vis-a-vis other investments in breakthrough therapies that we have to make. So, of course, we will continue to look for opportunities, but I would say at this point it's going to be more opportunistic. and that we're really looking at our investments in our development program to be competitive and to make sure that we have the ability to focus on breakthrough therapies. So I'd say that going forward it will be more opportunistic because we're just weighing and trading off so many incredible programs on the innovative side that we could also be doing.
spk05: Thank you, Angela. And also, you need to take into consideration, Ronnie, that we have right now so much substrate in our R&D pipeline and so much opportunity to invest. But right now, we are clearly focusing on first-in-class and particularly best-in-class, first-in-class. And there are so many, right? So that's why our R&D budget is increasing. So thank you very much. Back to you, Chris.
spk02: Thank you, Albert. Operator, next question, please.
spk17: Your next question comes from Jeff Meacham from Bank of America.
spk07: Good morning, guys. Thanks for the question. Just have two. For Michael, on COVID boosters, when you look at the new cases of the Delta variant, the protection varies quite a bit in vaccinated individuals, really depending on geographies around the world. So, are there common themes that you've identified that could explain this? And what can you say about the T cell dynamics from the vaccine over time? And then second question for Albert or for Frank, you're just given the guidance hike from the COVID vaccine. Does this change Pfizer's urgency or size of your capital allocation decisions? I would think that this would give you maybe more deal capacity to get over the LOE period at the end of the decade. Thank you. Thank you very much.
spk05: Let me start with that. I'm sure Frank would say the same, the second one. We always have this urgency and this extra cash inflows do not change neither our strategic direction, not materially our ability to perform these deals. Clearly give us better flexibility and we plan to allocate capital to develop the business with a very big sense of urgency. Now the COVID boosters and your question about why we see differences around geographies. In fact, actually, as Michael will explain in a moment, the data from all geographies are consistent if you take into consideration the time element. But, Michael, please take it.
spk06: Yeah, you said it very well, Albert. We first get the glimpse from real-world evidence in Israel, given the very rapid, massive vaccination they did over basically January to March. And January started with older adults and those more vulnerable. They are now six to eight months, and they have a large number of them. So that's why they see the vaccine waning, and that's why they also communicate about their consideration for a third dose. Other countries that started later and amping up the rollout slower, will and are starting to see similar trends representing what Israel saw in June. And we are getting those reports which tells us we are increasingly certain that what we have learned from Israel is likely to be a similar direction in many other places. Of course, we need to get all of that data in order to be fully clear about this, but the trends look similar. Finally, there is also an element that some countries, particularly UK, extended the interval between dose one and two to a longer interval. Likely they will get a bit more long-lasting protection, and their data may come a few months later. The disadvantage of extending the range between dose one and two is that you expose after dose one many individuals to a high risk of reinfection, but you do gain likely a somewhat extended protection. So these are two examples. When you started to vaccinate, the time difference between dose one and two. And finally, there may be, of course, some difference in care of this type of diseases in different countries. But all in all, we expect it to look somewhat similar in its direction.
spk05: And just to clarify, when Michael says extended because they spread the first between the second, it's not that they would get more after the second. It is that the real protection starts later from the second dose. And this is the case that most of the data in the UK, for example, are one to three months. And most of the data in Israel, when we see it, is in three to six months. And most of the cases are happening there. And we have also visibility to other data, including some data that are forming here in the U.S. But the trend is the same. It's pointing to the same direction. But you have very good protection in the beginning. Then there's a waning when you come closer to six months, which is even more profound with Delta. and waning is more profound for mild cases, but there is a clear waning also for hospitalizations and severe diseases. What used to be 100% in the first months now is coming to the low 90s and in cases to the 80s. So that's the difference between the different geographies. The time element you will see very, actually impressive consistency. Okay, Chris, back to you.
spk02: Thank you, Albert. Sylvia, next question, please.
spk17: Your next question comes from Andrew Baum from Citi.
spk15: Many thanks. Firstly, in relation to Prevnar20, could you talk to how you expect ACIP to address the current recommendation for pneumovacs? Is that dropped given the stereotypes which you are now addressing with Prevnar20? Second, you commented on a number of your other vaccines. You didn't comment on your C. difficile candidate where the primary endpoint is rapidly approaching. Could you just comment on your relative degree of optimism or not for that vaccine? And then finally, in relation to the patient assistant program for Ibrant, just looking at the script trends for Vazenio versus Ibrant, There's clearly a disconnect there. It could be due to the patient assistance programs, but it would be helpful to know the magnitude of which the PAP contributes and how that has changed over the last six months or so. Many thanks.
spk05: Thank you. Michael, do you want to take first this question you didn't speak about? I think it was CDEF that you referred to.
spk06: Yeah, yeah.
spk05: Are you really confident why you did that?
spk06: Well, we had such a rich pipeline, and we thought that we wanted to allow you to have questions too and not speak too much ourselves. So we selected eight assets where we thought we wanted you to hear some updates. We continue with the trial. We passed one review that had 30 cases, and we're coming now to case numbers that are more sizable that you would expect to be able to relatively soon have an opportunity to determine if vaccine efficacy is robust and you will be able to have a readout. We are expecting this fall to have another readout in that file pending events. But certainly, I continue to believe it's a very well-designed vaccine. There is precedent with antibodies if you utilize those toxins. So I continue to say, be patient. We continue to mature the study. And I do hope it will have an encouraging readout. But like in any clinical study, you can never be fully certain about the outcome, but I remain very encouraged and optimistic myself.
spk05: So, thank you, Michael, and Andrew, just to clarify, no, it's not that there was something behind it. It is that we had to select a few assets that we could present new data. Angela, please take the question about Numovax, what do you think ACIP will do, and the program of IBRA, the PATH program.
spk13: Sure. Well, the question of Pneumovax is something that we can refer to in the ACIP discussion that was had recently. Again, it comes back to the policy questions that were posed. And clearly there, just to reinforce what I said earlier, which was that there were different policy questions posed for both PCV20 as well as MERV15. The question of whether 50-plus would be vaccinated with POSE only for PCV20. And specifically, your question about Pneumovax, that is being evaluated only with MERC-15, not with PCV20 or with any PCV. So again, different policy questions and very specific to each pneumococcal vaccine. And then going to your question about the Pap usage, You know, we are seeing this clearly as a trend that is very much aligned with the economic hardships that we're seeing, you know, as a result of COVID and the pandemic. The Iran patient is a younger population. And so, and because they're on commercial insurance, their economic status is very much then aligned to employment. And what we're seeing throughout the pandemic are two things. One is a slowdown in new patient starts, which actually is one of the reasons for the negative growth that you saw in eye brands in the U.S. And the second and more prominent one this quarter is the PAP. So I think what you're seeing here is very consistent with what we're seeing in the environment generally as it pertains to economic hardships. And so that is definitely one explanation. And then the other explanation would be a slowdown in the new patient stock that we've been seeing as well.
spk02: Thank you, Angela. Thanks. Sylvia, next question, please.
spk17: Your next question comes from Carter Gould from Barclays.
spk04: Good morning. Thanks for taking all the questions, and I appreciate all the color in the pipeline from Michael. A couple from us. You gave us a pretty comprehensive set of updates, but in terms of expectations on timing from the pediatric study, I don't believe I saw that referenced and just wanted to confirm that the recent asks from FDA haven't pushed timelines back there. And then as we think about the oral proteasome inhibitor, clearly have moved very fast there. Can you comment just around your ability to supply the market in bulk, sort of out of the gates, assuming the timelines are tracking kind of how you're messaging? And then apologies if you guys addressed this already, but it seems like one of the things you guys do control is, on the JAK side, is the potential presentation of the JAK oral surveillance data, any color and when we might see that presented at a medical meeting. Thank you.
spk08: Yes.
spk05: Let me take quickly the first two, and then for the JAK, Michael, maybe you can . The pediatric study, we are As you said, as we have said, we are projecting into September, immediately after summer to be due. But FDA has asked some requirements and we are looking at them. But our intention is to try to, even with these requirements, to try to come uh in the same time frame so we are not changing right now our expectations as to when the study can recruit with us if we need to do more in less time we will try to to accommodate that so that's the first one on the oral supply on the oral and the supply as you know this is not a a compound that we have seen clinical efficacy data yet. So the risk is clearly higher than anything else. But of course the disease is moving. So I have authorized our team to invest in manufacturing at risk significant quantities of the oral so that if we are successful, we will have quantities for the world as much as possible. That's a significant investment that we are doing. At risk, it could go all the way to a billion, including some of the research work that is happening. But I think it is the right thing to do, and I gave them the green light. They should not be thinking about cost right now. They should be thinking about the success of the oral program. And then for the Zach, Michael, do you know when the study will be published or the results?
spk06: You know, we have focused to share all the data of the study obtained thus far with regulators. And as you know, conclusions have already been posted about the data from both European, like the PRAC Committee, and U.S. So while there isn't a date yet when the study will be published, regulators have had access to it and have made updates. So I think the most critical element is for the U.S. European regulator to finalize things. And like Angela spoke to, that will give clarity to the class of JAK and to CELIANS and which patients with treatment lines that benefit And as you know, in addition to the study, we have years, 10 years of surveillance. And we continue to share all of that data as the study was mainly in a subset of patients with increased age and cardiovascular risks. While, of course, our surveillance carries all patients, And we have continued to shed those robust data. Thank you.
spk02: Thank you, Albert. Operator, next question, please.
spk17: Your next question comes from Jeffrey Porges from SDB LRINC.
spk16: Thank you very much for taking the question. Michael, one for you. You mentioned the Delta Plus variant. which, of course, has picked up the K417N mutation. How concerned are you about Delta Plus? And then is there the possibility that, of course, it'll pick up E484K and then be even more resistant to vaccine-induced immunity? And relative to that, do you have a view yet as to whether the best booster strategy is the original Wuhan strain, the beta strain, the Delta strain, Delta Plus strain, And then lastly, have you contemplated heterologous boosting with your vaccine after, for example, the Chalox vaccine or vice versa? Is that something you're studying?
spk06: Michael? Yeah, you know, starting with Delta Plus. So right now, Delta is a very fit virus and continue to infect and dominate. It's too early to know whether N of the current delta plus will have transmission sufficiently to outcompete delta. So when we say plus, it means just continue to monitor into the future at some time point, whether six or 12 months, there are likely going to be strains that pick up additional mutation, but stay also fit. Meanwhile, What we have seen with the wild-type vaccine is that we see for each dose not just a higher magnitude of antibody, but breadth, the repertoire of different cells producing antibodies grows and grows. So you seem to cover, with increasing dose, more variants. If you go back and look at the slides, we use the beta variant as an example. somewhat of a difference after dose two, harder to utilize the beta variant, after dose three, easier to utilize the beta variant. So that's why we, this far, find the wild-type boost very useful for existing and new variants. Now, as Albert has said before, we always want to be prepared for the unexpected. And we continue to prepare Delta and Delta Plus strains. But right now, we do think that the wild-type vaccine is going to be very efficient. But we always want to be ahead of the curve. I think the way to win this game is to keep up high immunity, reduce the amount of virus. And that's why we do both vaccines. We've started boost with existing and are prepared, if ever needed, to have an updated if the virus can be fit and breaks through immunity. Finally, on the heterologist boost, there are trials coming out performed, for example, in UK that showed favorable outcome for those that vaccinated with AstraZeneca on getting an mRNA boost, such as with the Pfizer-BioNTech, which they used. Those are data that you should review, and I'm sure patients and physicians will draw their own conclusions. I know there is, in the U.S., similar studies to benefit from that mRNA vaccines can be given repeatedly, while adenovirus-delivered vaccine has limitations for repeat use.
spk05: Thank you, Michael. And again, I want to emphasize that our strategy when it comes is that we take no chances here. This is too serious to risk. So when we have a variant that it is of concern, always we make immediately at risk a vaccine to try. The first time we had that was better. That seemed very aggressive. So we start doing the vaccine, and we have a vaccine right now. We are going to submit it to the FDA. Eventually, we don't need it. It was very clear because after we did that, we got data for immunogenicity, but also we got the South African study that gave 100% efficacy in the better or smaller numbers, but 100% efficacy. So we know we don't need it. But we tried. The same we do now with Delta. Looks like we will not need it with everything that we see so far. But we are developing one in the backstage. So in case something goes wrong, because biology is sometimes unpredictable, we will not have to wait three months, because this is our time right now. From the day we assign a variant as a variant of concern in our own interpretation, we take 95 days. to be able to have a vaccine. So that's why we always try to be ahead of the curve. That's too serious of an issue to take risks. Back to you, Chris.
spk02: Thank you, Albert. Sylvia, next question, please.
spk17: Your next question comes from Louise Chen from Kantor.
spk01: Hi. Thanks for taking my questions. So first question I have for you is do you think a full BLA approval would actually increase vaccination rates? And do you think you might see that as early as this year? And then secondly, how receptive do you think U.S. regulators are to a booster shot? We see a lot of conflicting headlines. I'm just curious what your discussions have sounded like there. And then lastly, your RSV vaccine, you showed 100% efficacy rate. So just curious if you could elaborate more on that market opportunity for you and how big that market is in terms of sales and other metrics. Thank you.
spk05: Yes. On the vaccination rate, Luis, from a From what I see and what we see in the different polls from people that they are reluctant, it seems that this will play a role. Some people will change their reluctance to willingness to get vaccinated if the vaccine gets full approval. And in terms of the timelines, again, I leave it to FDA. I know that they consider that a priority. The second, how receptive regulators are on a third dose, I think regulators are receptive or not to data. And they need to see the full package of data. Once they see it, they have to speak. So I don't want to make comments about that. And RSV, which is clearly a very, very large opportunity, but it is growing even more because of the, we see that the epidemiology of the disease is getting more and more hot. I will ask Michael to give us some color here.
spk06: Yeah, you know, we are very excited about the data and opportunity for an RSV adult vaccine. There are 100,000 of cases per year in the U.S. and they are particularly, of course, difficult for older adults above 60 or adults that have underlying conditions, whether chronic lung diseases or immune compromise. Now, there are actually up to 15,000 deaths just in the US annually. So it's not just about a difficult disease or a fatal outcome. So we think there is a very large opportunity. Now, with our vaccine, to the best of our knowledge, it's the only vaccine in late clinical trials that target RSV A and B subgroups. Please recall that the A and B subgroup variants are likely of similar quantities circulating. Some years one is larger than the other. Some years they are equal. So we cover all of the available RSE protection by a bivalent vaccine if shown successful in the final studies. Also, I wanted to make it clear that when you look at the data in our challenge study of the very prominent 100% protection, there are benchmarks published. And please have a look from the adenovirus that is also now in advanced clinical trials, which showed in the very same model pursued by the very same UK institute, half of the response, around 50%. So we think we have a potent vaccine. We have a well-tolerated and a unique aspect of covering both strains. You have some cross-reactivity between the strains, but not as good protection unless you have both parts for the A and the B strain. Angela, anything you want to shed light on how you commercially see this?
spk13: Thanks, Michael. And maybe just to reinforce what Michael said, which is that there are hundreds of thousands of older adults that are hospitalized and tens of thousands of deaths each year. In fact, this is the second leading cause of a respiratory illness following flu. So we think that we have a great opportunity to, in fact, develop this market because it is quite underdiagnosed today and underreported. And frankly, it's really in the sweet spot of what we do with adult vaccinations and also seasonal vaccinations, which go well with our PrEP-NAR franchise. So all in all, a tremendous and exciting commercial opportunity.
spk05: Thank you to both. As you can see, there is a lot of excitement to both Angela and Michael. And I serve the same both for the size of the unmet medical need right now, but also for the capabilities of what looks like a very effective vaccine remain to be proven with a phase three study that we are going to execute with the same speed as we are doing lately, our vaccine studies. Back to you, Chris.
spk02: Thank you, Albert. Sylvia, we're just over time, but maybe we could do one very brief question, please.
spk17: Your next question comes from the line of Terence Flynn from Goldman Sachs.
spk18: Hi, thanks for taking the question. Maybe I just had a 2 part or 1st, just wondering if you can provide the latest point estimate on your vaccine efficacy from the phase 3 trial. I think you gave us that number back in April. It was around 91% and just wondering if there have been any severe cases in the vaccinated cohort and then on Prevnar 20. How are you thinking about that in the context of your long-term guidance? Can that actually grow your Prevnar franchise significantly in any more detail you can provide there? Thank you so much.
spk05: Michael, it was, I think, 92%. Can you comment on the latest estimate and if you have seen any breakthrough?
spk06: Yeah, you know, this is the phase three trial that will be very soon published on MedArchive, and it will appear in a top peer-reviewed journal. Please check in on MedArchive to get details. It may be up any day this week. You know, it's covered up to six months. First two months, 96% protection. Then above 90s between months two and four. And then about 83 to 84% months four to six. We have retained during that period very high protection against severe disease and hospitalization.
spk05: Thank you, Angela. Michael, excuse me. Angela, about the PREVNR, do you think you can grow it? I'm asking you to do it, but what do you think?
spk13: Well, I think, again, it comes back to the policy questions that have been posed already by the ACIP, which will be discussed in October. As we've said today, there are really two questions being posed that are different to what we have with PREVNR 13 today, which is, number one, the ability, should we or should we not be vaccinating those that are 50 plus, and then secondly, those that are immunocompromised, 18 to 49 or 18 to 59. Both of those populations are different to what we have with 13. So we are engaging and we will be engaging at the ACIP, of course, discussing our data with the relevant decision makers and stakeholders and sharing our information. And, you know, we hope to have a positive outcome at the end of ACIP. But honestly, this is all to be discussed, and I think a little too early to speculate what could happen. We need to have a robust scientific discussion to really understand what these opportunities are.
spk05: Okay, Angela. We will give you some time to grow it. So with that, I think we've come to the end. Thank you for joining us today, for your continued engagement with Pfizer. We really appreciate it. We learned a lot from this engagement. Our experience with the COVID-19 vaccines have taught us a great deal about what is possible and what is impossible. And most things are possible. So most notably, it has taught us that we can drive step changes at Pfizer, not just incremental changes. To keep you updated on the progress we are making in R&D, we will host our next focused investor update later this year. A date will be announced soon. For this event, the Pfizer vaccine team will provide an update on our vaccine pipeline progress, including our plans to continue advancing our cutting-edge science in such areas as mRNA programs for COVID-19 and flu as well as the RSV research programs for both maternal and adult indications and other mRNA vaccines that we are working on. Before we close, I want to once again thank Chuck Triano. Chuck for his many contributions to Pfizer and for successfully elevating our investor relations function to the best in class. Chuck, you are a pro. And on behalf of all Pfizer colleagues, I wish you and your family All the best in the next chapter of your life. Chuck is leaving behind some big shoes to fill, which is why you are thrilled that Chris Thibault has decided to join the Pfizer team. Chris joins us from the election pharmaceuticals in Boston, where he was vice president and head of investor relations. He brings a wealth of experience as a buy-side analyst and portfolio manager, as well as a strong network of relationships across the investment community. His deep knowledge of the healthcare industry would be a great asset as we continue to advance our innovative pipeline to deliver breakthrough therapies and vaccines to patients and long-term value to shareholders. With that, I will bring our call to a close. Thank you for joining us. Have a great rest of your day.
