Thank you for standing by and welcome to the BioNTech Second Quarter twenty '20 Operational Progress and Financial Results Call. At this time, all participants are in a listen only mode. There will be a presentation followed by a question and answer session. I must advise you this call is being recorded today, Tuesday, 08/11/2020. And I would now like to hand the call over to the Vice President, Investor Relations and Business Strategy, Silke Marrs.
Please go ahead.
Speaker 1
Thank you for joining us today for BioNTech's second quarter twenty twenty update call. Before we start, we encourage you to view the slides for the webcast as well as operational and financial results press release issued this morning, both of which are accessible on our website in the Investors section. As shown on Slide two, during today's presentation, we will be making several forward looking statements. These forward looking statements include, but are not limited to the timing of enrollment, initiation, completion and reporting of data from our clinical trials, the potential registrational nature of certain clinical trials, the impact of the COVID pandemic on our business and financial outlook, the timing for any potential emergency use authorizations or approvals for BNT162, the potential safety and efficacy of BNT162 and the ability of BioNTech to supply the quantities of BNT162 to support clinical development and if approved market demand, including our production estimates for 2020 and 2021. Actual results could differ from those we currently anticipate.
You are therefore cautioned not to place undue reliance on any forward looking statements, which speak only as of the date of this conference call and webcast. Speaking and available for question today will be Ugo Zein, Chief Executive Officer, Urslan Poreci, Chief Medical Officer, Jean Merritt, Chief Business and Commercial Officer, Silk Potting, Chief Financial and Operating Officer and Ryan Richardson, Chief Strategy Officer. I now hand the call over to Uger Zahin, BioNTech's CEO.
Speaker 2
Thank you, Zoeke. It's a pleasure to welcome you to our second quarter twenty twenty conference call. The last few months have been a game changing time for BioNTech. The groundbreaking potential of our technologies as well as our ability to quickly respond to new challenges and execute fast has been on full display. One key highlight is the initiation of the pivotal Phase IIb free trial of our lead BNT162 COVID-nineteen vaccine candidate within six months of starting the lifespan vaccine discovery, preclinical and clinical research program.
In parallel to the COVID-nineteen program, we have continued to advance our oncology pipeline and broadened our base of strategic collaborations. I'm happy about the accomplishments we have made in the second quarter and would like to thank our entire team and also our partners for their tireless efforts and outstanding commitment. Slide five summarizes some of our key highlights since our last quarterly update. We reached a number of important milestones over the past few months. We continue to advance our clinical stage pipeline.
We now have 12 immunotherapies in clinical testing across three drug classes that includes eight messenger RNA therapeutic programs, three antibody programs and one small molecule immune modulatory program. In July, we and Pfizer selected BNT162b2 as our lead COVID-nineteen vaccine candidate and initiated a pivotal Phase 2b free trial. We have made progress in ramping up our manufacturing capacities to support global supply. We have signed commercial supply agreement with multiple countries around the world for more than two fifty million doses in 2020 and 2021. This also includes an option to purchase up to 500,000,000 additional doses.
All this is subject to regulatory approval. In parallel to our effort to bring COVID-nineteen vaccine to the market as quickly as possible, we also continued to advance our oncology pipeline. As we will provide the key updates later in the call, including for our INS program, BNT122 or our BNT111 six act melanoma program. Here, we announced a new collaboration with Regeneron to combine BNT111 with Libtayo and anti PD-one in a randomized Phase II trial, which we believe could have a registrational potential. Moreover, we significantly strengthened our balance sheet, bringing in commitments of approximately $1,100,000,000 in gross proceeds from non dilutive upfront cash payments and equity and debt financing commitments.
These accomplishments have strengthened our ability to advance our pipeline on multiple fronts and deliver on our longer term vision to bring novel immunotherapies to patients across a range of diseases. Moving to Slide six, I would like to touch on the importance of our strategic collaboration. This is important because these collaborations continue to play a crucial role in how we are building our business. Our partnerships extend our execution capabilities and global reach, and in some cases provide us the access to external technologies, such as Genmab's dual body technology, which are highly complementary to our own. In the 2020, we expanded our existing partnership with Pfizer to jointly develop our COVID-nineteen vaccine program.
In addition, we have established a new collaboration with Regeneron in the oncology field. The important aspect here is that we have retained significant economics on our programs through these collaborations. Sean will provide some further details on the Pfizer collaboration later in our prepared remarks. In the case of Regeneron deal, it is important to note that each party keeps 100% of the rise to its own product. That means that BioNTech has kept full product commercialization rise for BNT111 melanoma six pack.
On Slide seven, you'll see an updated version of our multi platform immuno oncology strategy. The cornerstone of this strategy is to leverage our immunotherapy expertise with new therapeutic approaches to target cancer and modulate immune responses simultaneously. We believe the approach can produce multiple blockbuster product opportunities, but also will enable the development of powerful combination treatment approaches, which combine complementary mechanisms of actions. Despite the challenges associated with the COVID-nineteen pandemic, we have continued to execute our immuno oncology strategy on multiple fronts. We are on track to initiate multiple late stage trials for six pack and INS product candidates.
We are anticipating the first data update for our next generation checkpoint immunomodulator BNT111, a bispecific antibody targeting anti PDL one and four-1BB later this year. Furthermore, since our last earnings call, we have initiated a Phase onetwo trial for our TLR7 agonist small molecule immune modulatory program and expect to initiate first in human trials for two novel cell therapy approaches in the coming months, including BNT211 and first CAR T cell therapy and for BNT221, our neoantigen T cell therapy. As we have done in the past, we will continue to be data driven in how we assess each product opportunity we take into clinical testing. I will now turn it over to Esven to provide an update on our programs.
Speaker 3
Thank you, Ugo. In the interest of time, I'm going to focus my remarks to the four programs highlighted on Slide nine. These include BNT111, our fixed fat melanoma, BNT122, our INAS program, BNT311, our anti PD L1 anti-41BB antibody and BNT411, our TLR7 agonist. For further details on the status of other programs, please refer to our full quarterly update, which was released this morning. So, let's start on slide 10 with BNT111, our melanoma fixback program.
As a reminder, BNT111 is composed of four non mutated melanoma antigens, NY ESO1, MAGE A3, tyrosinase and the novel antigen from our own libraries TPTE. In July, we published interim Phase one data in Nature from our ongoing Lipomeric trial. The Lipomeric trial is a multi center open label dose escalation study to evaluate safety and tolerability of vaccinated patients with stage three BC and stage four melanoma. Efficacy was evaluated in a subset of forty two checkpoint inhibitor experienced patients with a data cut off in July 2019. As I reported earlier, extraction date, three patients out of twenty five in the fixed fact monotherapy group experienced a partial response, seven patients showed stable disease, and one patient showed a complete metabolic remission of metastatic lesions.
Of the seventeen patients treated with the combination of six vec of BNT111 and an anti PD-one, six patients showed a partial response. Of note, at our target dose for the Phase two trial of one hundred micrograms, we observed that five of ten patients had a partial response to FixVac in combination with anti PD-one therapy. The publication in Nature summarized on slide 11 highlighted extensive biomarker and immunological data. These support the mechanism of action and the observed clinical activity of FixVac alone and in combination with anti PD-one. Importantly, treatment with BNT111 resulted in the expansion and activation of circulating tumor antigen specific T cells with memory function that exhibited strong cytotoxic activity against tumor cells.
These vaccine induced T cells displayed a Th1 phenotype. In twenty patients tested by post IBS interferon gamma E spot all showed immune response against at least one of the used tumor associated antigens. Most patients demonstrated CD4 or concurrent CD4 and CD8 T cell responses. In fifty patients tested by ex vivo interferon gamma eighty spot, which only captures high magnitude responses, more than seventy five percent of patients showed immune responses against at least one tumor associated antigen, most of which were high magnitude CD8 positive T cells. T cells ramped up within four to eight weeks to single digit or low double digit percentages of total circulating CD8 positive T cells.
Under monthly maintenance treatment, levels of T cells continued to slowly increase or remain stable up to over one year. Safety was assessed in eighty nine patients. Overall, six pack treatment was well tolerated with no dose limiting toxicity observed. Most common adverse events were mild to moderate transient flu like symptoms, such as pyrexia and chills. As Ugo mentioned earlier, we recently announced a strategic collaboration with Regeneron and plan to pursue an accelerated development program for the combination of FixVac and Regeneron's anti PD-one agent Libtayo in the second line treatment setting for advanced melanoma patients that have progressed after prior PD-one blockade.
Under the terms of the agreement, we and Regeneron have agreed to share development costs equally. If approved, each party will retain full commercial rights for their respective product and would record revenues related to its own product. We plan to initiate the randomized Phase II trial in the fourth quarter of twenty twenty and expect to provide more details on the study in the third quarter twenty twenty. Now moving to slide 12 to BNT122, our individualized neoantigen specific immune therapy or INES platform program, which is partnered with RocheGenentech. A data update for the Phase 1a monotherapy and 1b combination with Tecentriq basket trials in multiple solid tumors was reported in June as part of the AACR Virtual Annual Meeting two.
This is the first time that we have shown safety and immunogenicity data across different tumor types outside of melanoma. The patient populations in these cohorts were heavily pretreated, many with refractory and recurrent disease with a high proportion of low PD L1 expresses. Treatment with BNT122 alone and in combination with Tecentriq was well tolerated, with the majority of adverse events being grade one or grade two, and there were no dose limiting toxicities. In the majority of patients treated with VNT122 alone and in combination with T centric, ex vivo T cell responses against multiple neoantigens were detected. We also detected BNT122 induced T cells in infiltrates of patients' tumors.
In the Phase 1a monotherapy portion of a trial, twenty six patients underwent at least one tumor assessment. One patient of those with gastric cancer and metastatic liver lesions had a durable complete response and remains on study after one and a half years and twelve patients had stable disease. In the Phase 1b combination portion of the trial, in one hundred and eight patients that underwent at least one tumor assessment, one patient had a complete response, eight patients had partial responses, and fifty three patients had stable disease. We continue to believe that INEST is well suited to earlier lines of therapy across a range of solid tumors. We have depicted our ongoing Phase II trial in first line melanoma and our planned adjuvant clinical trials for I MIST on slide 13.
We expect to provide an enrollment update from the randomized Phase II trial of BNT122 plus pembrolizumab in first line melanoma in the 2020 and an interim data update is anticipated in the 2021. We are going to start two Phase II studies in the adjuvant setting. One is in an IO sensitive cancer type, namely evaluating the efficacy and safety of INES plus Tecentriq compared with Tecentriq alone in patients with early and adjuvant stage non small cell lung cancer. The second study is in an IO insensitive cancer type, namely a multi site open label phase two randomized trial to compare the efficacy of INEST versus watchful waiting in patients with circulating tumor DNA positive stage two high risk and stage three colon cancer. Now moving to slide 14, to the two DuoBody programs we have partnered with Genmab.
On slide 15, you see one of them BNT311, the anti PDL1, anti-41BB bispecific antibody that combines constitutive CPI blockade and conditional co stimulatory activity, a mechanism of action which led to enhanced proliferation of antigen specific activated T cells in the presence of PD L1 positive cells in preclinical studies. Based on the preclinical data we have generated, we believe this molecule could represent a powerful new checkpoint immune modulator with therapeutic potential across a range of solid tumors. We expect to provide the first human data in the 2020. This update will include dose escalation status from the Phase onetwo trial in multiple solid tumors. We believe it has broad potential in a range of solid tumors, including those where checkpoint therapy is currently established, but also in more difficult tumors where first generation checkpoint inhibitors have not been as successful.
Finally, now turning to slide 16, we recently initiated clinical testing for BNT411 from our Toll like receptor binding program. This molecule is engineered for high potency and has high selectivity for the TLR7 receptor at the therapeutically active dose range. We expect this molecule to activate both the adaptive and innate immune system, in particular in combination with cytotoxic therapies and checkpoint inhibitors. Preclinical studies suggest a type one interferon dominated release of cytokines and chemokines and potent stimulation of antigen specific CD8 T cells, but also B cells and innate immune cells such as NK cells and macrophages. In early July twenty twenty, the first patient was dosed in a Phase one2a first in human open label dose escalation trial with expansion cohorts to evaluate the safety, pharmacokinetics, pharmacodynamics and preliminary efficacy.
BNT411 will be tested as a monotherapy in patients with solid tumors and in combination with Tecentriq carboplatin and the toposet in patients with chemotherapy naive, extensive stage small cell lung cancer. Now, were the highlights from our oncology programs. I'll now provide an update on our COVID-nineteen vaccine program. Now moving to slide 18, which recaps how far we have come in the race to develop a COVID-nineteen vaccine. We began work on multiple vaccine candidates in late January, following news of the coronavirus outbreak in China.
Approximately six months later, we initiated a pivotal Phase 2b free trial aimed at supporting an approval of our vaccine in The US. Our goal with Pfizer is to be in a position to file for approval or emergency authorization from the FDA as early as the 2020, if the trial hits our enrollment targets and is deemed to be successful. I will come back to the Phase IIbFree trial design in a few minutes. On slide 19, you see the four vaccine variants we have taken into clinical testing. These variants vary based on the type of mRNA construct used and the antigen target.
Two of the variants target the RBD domain and the other two the full length spike protein. Both our B1 and B2 candidates have received FDA fast track status. In late July, we along with Pfizer selected BNT162b2 as our lead candidate for the Phase IIb3 trial. BNT162b2 encodes for a modified version of a full spike protein and utilizes our nucleoside modified RNA construct. The decision to advance BNT162b2 was made after an extensive review of the preclinical and available clinical data and in consultation with the FDA.
For the Phase 2b3 trial, the thirty microgram dose level in a two dose regimen was chosen. Now moving to slide 20. BNT162b2 vaccinated participants displayed a favorable breadth of epitopes recognized in T cell responses specific to the SARS CoV-two antigen. The candidate also demonstrated concurrent induction of both high magnitude CD4 and CD8 T cell responses. These T cell responses were observed against both the RBD and the remainder of the spike glycoprotein.
We believe that immune recognition of more spike T cell epitopes may have the potential to generate more consistent responses across diverse populations and in older adults. Preliminary data for BNT162b2 suggested a favorable reactogenicity profile. Systemic events were generally mild to moderate and transient lasting one to two days. Events included fever, fatigue, and chills. There have not been any serious adverse events observed in our BNT162 program.
Data collection from the Phase onetwo trials for all four vaccine candidates is continuing. We plan to submit data on BNT162b2 for peer review and potential publication in the next few weeks. We also intend to also post the manuscript on a preprint server at that time. Moving to slide 21, I'd like to spend a few minutes to outline the design of our ongoing Phase 2b free trial. The study is expected to enroll up to 30,000 participants aged 18 to 85 years, starting in The US and expanding to include approximately 120 sites globally.
The trial regions will include areas with significant anticipated SARS CoV-two transmission. The phase 2b free trial is a one to one vaccine candidate to placebo randomized, further blinded study to obtain the safety, immune response and efficacy data needed for regulatory review. The primary endpoint is prevention of COVID-nineteen in participants without evidence of SARS CoV-two infection before vaccination, as well as prevention of COVID-nineteen in participants regardless of, SARS CoV-two infection before vaccination. The primary efficacy analysis will be an event driven analysis based on the number of participants with symptomatic COVID-nineteen disease. We will use polymerase chain reaction to confirm infection COVID-nineteen of SARS CoV-two and antibody tests to confirm previous exposure.
One of the secondary endpoints includes prevention of severe COVID-nineteen disease. The trial design allows for interim analysis and unblinded reviews by an independent external data monitoring committee. Assuming clinical success, we along with Pfizer may potentially seek regulatory review in Q4 as early as October 2020. With that, I will now hand over to Sean to provide an overview on our commercial updates.
Speaker 4
Thank you, Ugor. I will start by recapping our commercial arrangements with BNT162 with Pfizer and Fosun depicted on Slide 22. Our collaboration with Pfizer involves co development of a portfolio of COVID-nineteen vaccine candidates on a worldwide basis excluding China. Upon approval, we would jointly commercialize the vaccine with Pfizer. As part of our preparation for commercialization, BioNTech is taking steps to establish a limited commercial infrastructure in a selected set of countries while leveraging Pfizer's commercial infrastructure and capabilities in the rest of the world, excluding China as I've just noted.
In terms of financials, our collaboration with Pfizer is based on a fiftyfifty partnership. Both companies share development expenses and gross profits worldwide on a fiftyfifty basis, regardless of which company distributes the vaccine in a given country. Furthermore, capital expenditures are funded by each party independently. In addition to the combined upfront payment and equity investment of $185,000,000 BioNTech received in April, BioNTech is eligible to receive further development and sales milestones of up to $563,000,000 If reached, these milestones will come in addition to BioNTech's 50% share of gross profits generated. Our collaboration in China is also a co development agreement.
However, Fosun funds the majority of development expenses incurred in China and would take on commercialization responsibilities if the vaccine is approved. In addition to the combined upfront payment equity investment totaling US51 million dollars which was received in April, Beyonce is eligible to receive further development and sales milestones up to US84 million dollars Beyonce would also share gross profits on the sale of the vaccine in China. I will now turn to Slide 23 to provide an overview of our recently announced commercial supply agreements. From the beginning, we have been very clear about our intention to make our vaccines available for global supply to address the pandemic. And we are investing at risk to scale up our manufacturing to enable us to do so.
BioNTech and Pfizer have a target to manufacture up to 100,000,000 doses by the 2020 and approximately 1,300,000,000 doses by the 2021. This estimate assumes a continued ramp up in production at Ida Oberstein and Mainz facilities in Germany, which are currently producing vaccines for clinical supply. We're also working with Pfizer to activate and ramp up vaccine production at several Pfizer sites in The United States and one in Europe. While it is still early, we have announced commercial supply agreements with the governments of multiple countries for more than two fifty million doses with an option for an additional 500,000,000 doses. Furthermore, we're currently in a number of discussions with governments around the world in relation to further commercial supply.
All agreements are subject to clinical success and regulatory approval of the vaccine.
Speaker 5
I will now hand over to Sip to provide an update on our financials. Thank you, Sean. Now I would like to summarize our financial results for the quarter that are shown on Slide 25. Our total revenue, which primarily consists of revenue from our collaboration agreements, was €41,800,000 for the second quarter twenty twenty compared to €25,800,000 for the second quarter twenty nineteen. For the period of six months ended 06/30/2020, our total revenue was €69,400,000 compared to €51,900,000 for the comparative prior year period.
The revenue from collaboration agreements overall increased due to the recognition of revenue from our new collaboration agreement signed with Pfizer and Fosun Pharma as part of our BNT162 vaccine program against COVID-nineteen. The revenues from other sales transactions increased due to increased orders and include sales of diagnostic products, peptides, retroviral vectors for clinical supply and development and manufacturing services sold to third party customers. Research and development expenses were €95,200,000 for the second quarter twenty twenty compared to €53,400,000 for the second quarter twenty nineteen. For the six months ended 06/30/2020, total research and development expenses were €160,300,000 compared to €110,600,000 for the comparative prior year period. The increase was mainly due to an increase in headcount, leading to higher wages, benefits and social security expenses as well as an increase in expenses for purchased research and development services, especially with respect to our BNT162 program.
In addition, from the date of acquisition, our new U. S.-based subsidiary, BioNTech U. S. Inc, contributed €5,300,000 to our research and development expenses. General and administrative expenses were €18,800,000 for the second quarter twenty twenty compared to €14,600,000 for the second quarter twenty nineteen.
For the six months ended 06/30/2020, total general and administrative expenses were €34,600,000 compared to €23,900,000 for the comparative prior year period. This increase was mainly influenced by higher expenses for purchase management consulting and legal services as well as an increase in headcount leading to higher wages, benefits and social security expenses. In addition, from the date of acquisition, our new U. S.-based subsidiary, BioNTech U. S.
Inc, contributed €1,600,000 to our general and administrative expenses. Net loss was €88,300,000 for the second quarter twenty twenty compared to €50,100,000 for the second quarter twenty nineteen. For the six months ended 06/30/2020, total net loss was €141,700,000 compared to €90,800,000 for the comparative prior year period. Turning to the balance sheet on Slide 26. BioNTech ended the second quarter twenty twenty with cash and cash equivalents of €573,000,000 or $641,600,000 Additionally, we raised €680,700,000 or $762,200,000 in gross proceeds from a private equity placement and our follow on underwritten offering after the end of the second quarter.
Considering these gross proceeds, the expected pro form a cash and cash equivalents balance at 06/30/2020, amounts to 1,250,000,000 or $1,400,000,000 Further, we announced a debt financing of up to €100,000,000 or $112,000,000 from the European Investment Bank in June 2020. All financing transactions are subject to closing conditions that were not fulfilled before 06/30/2020, and did not have an accounting impact within the second quarter twenty twenty. As a result of increased spending related to BNT162, we now expect net cash used in operating activities and for purchases of property and equipment to be between €450,000,000 and €600,000,000 for the full year 2020. We anticipate that existing cash and cash equivalents, the net proceeds from the recent underwritten offering and the expected net proceeds from the private investment announced in June 2020 will enable us to fund our operating expenses and capital requirements through at least the next twenty four months. With that, I will return the call back to Ryan for concluding remarks.
Speaker 6
Thank you, Sirk. Slide 27 outlines the key milestones we're focused on delivering as we look to the remainder of 2020. The first relates to our COVID-nineteen vaccine program, where the next major milestone is the Phase 2bthree trial we are conducting with Pfizer. As Oslan mentioned, we expect to be in a position to seek regulatory review as early as October 2020. In the meantime, we expect to publish Phase I safety and immunogenicity data for BNT162b2 in the next few weeks.
We also intend to publish preclinical data over the same time period. In addition, we anticipate three first in human data updates for our oncology programs over the course of the year, including for BNT114, BNT131, and our dual body program, BNT311. Data from our BNT-one 114 FixVac Phase I study in triple negative breast cancer has been accepted for an oral presentation at ESMO in mid September. The Phase I study is a three arm trial as a monotherapy and in combination with INEST evaluating safety and immunogenicity. The data to be presented will include a preliminary analysis of immune responses in TNBC patients treated with INEST.
For BNT131, our mRNA intratumoral immunotherapy program partnered with Sanofi, we expect the data update for our Phase onetwo trial in solid tumors in the 2020. The study is a first in human multicenter open label Phase one dose escalation and expansion trial to evaluate safety, pharmacokinetics, pharmacodynamics, and antitumor activity of BNT131, both as a monotherapy and in combination with ciniplimab in patients with certain advanced solid tumors. The data to be presented will include safety, tolerability, and pharmacodynamic biomarker data. While updates for these programs will focus on safety and immunogenicity, we expect that our preliminary update for BNT-three eleven, our bispecific antibody, will also include top line response data from our ongoing Phase onetwo trial. And finally, we plan to initiate up to six additional studies from our oncology pipeline over the remainder of 2020.
These include randomized Phase II trials for fixed VAC in melanoma and HPV16 positive head and neck cancers and for INEST in adjuvant NSCLC and adjuvant CRC cancers. We also anticipate initiating first in human trials for our cell therapy programs, starting with our CLDN6 CAR T cell therapy, the first program to incorporate our CAR T amplifying mRNA vaccine or CARVAC approach. And with that, I'll hand it back over to Uger for concluding remarks.
Speaker 2
Thank you, Ryan. I'm proud of what we have accomplished over the first half of twenty twenty and believe a tremendous opportunity lies before us. We thank our shareholders and partners for their trust and support. Let us open up the call for questions now.
Speaker 0
Thank you. Ladies and gentlemen, we will now begin the question and answer session.
Speaker 2
Session.
Speaker 0
Your first question comes from the line of Ahmad from Bank of America. Please ask your question.
Speaker 7
Hi, good morning. This is Bill Mahon on for Tazeen. So two from me. First of all, how do you think about distributing the initial doses that are going to be manufactured later this year of a potential COVID vaccine assuming approval? So the initial doses manufactured later this year and early next year, given that the first manufacturing batches won't immediately cover all supply agreements.
And then secondly, when you have to repay the Pfizer upfront investment out of profit sharing, can you help quantify what Pfizer has already put up in terms of upfront investment and what the pace of paying that back would be out profit share and milestones? Thank you.
Speaker 6
Yes. So I'll start with the first question. This is Ryan on the distribution side and then turn it over to Sirk, to comment on the second. So I think we're in the fortunate position, to have considerable demand, or interest in the vaccine as you can see from the supply deals that we've announced so far. Some of those deals do call for doses to be supplied in 2020, others in 2021.
I think we've indicated that by 2020, we expect to have up to 100,000,000 doses and then expect to be able to increase our capacity pretty significantly as we head into 2021. So I think we can't get into specifics at this point, but I think safe to say that we will already with the distribution agreements that we've announced, we feel confident that the doses that we can produce will be able to distribute across the countries that are included in those agreements. I don't know, Serge, do you want to comment on the second question?
Speaker 5
Yes, happy to. Yes, actually, so in the Q2, this was the first reconciliation that we did with Pfizer. And this quarter, we reconciled €20,000,000 as the total net cost on the Vionic side actually. This was the 50% of cost share for Vionic in this quarter. So compared with the total program, still a small amount because it was ramping up in April and May and June so far.
So €20,000,000 was recognized as a cost so far as our share.
Speaker 7
Okay. And I guess, how do you get to that €20,000,000 given the large numbers that Pfizer has kind of put out in terms of what they're investing in their manufacturing?
Speaker 5
Yes. So there's only a certain type of cost share. So not everything is shared fifty-fifty. So investments are investments into capacity is everybody's own cost, and what's shared is basically the development cost and scale up. So this is shared, and this is the €20,000,000 is our part of the share.
And so far, it's covered from our upfront that we received when signing the contract. Okay. Thank you. Sure.
Speaker 0
And your next question comes from the line of Cory Kasimov from JPMorgan. Please ask your question.
Speaker 8
Hey guys, thanks for taking my question. This is Matthew on for Cory. So I guess just wondering for BNT162, if you can talk a little bit about how you maintain the integrity of a Phase III blinded trial when a large proportion of BNT162 patients are expected to get fevers and other systemic AEs, and what your view is on whether this could impact the ultimate outcome of the trial?
Speaker 2
Yeah, thanks for the question. As First of we indicated in the press release, when we announced the selection of BNT162b2, we indicated that B2 is significantly better tolerated than the V1. So actually only a little fraction of vaccinated individuals have fever. And with regard to other symptoms, you might have seen that even placebo vaccinated subjects have a number of background symptoms. So we believe that we have a very good overall situation to avoid any type of bias mediated by the understanding of the participant that he might or she might get the vaccine and not the placebo.
Speaker 8
Okay, great. And then just wondering if you can walk us through your assumptions or essentially what needs to happen for the phase three program, to get data and a potential regulatory filing in October. And just I guess maybe if you can help quantify how dependent this is on either enrollment or infection rates or what might be the key factor in the timeline.
Speaker 2
Yeah, so this is a efficacy trial. That means at the end of today, are comparing the number of infected infections in the placebo versus in the treatment group. We are online evaluating in a blinded session the safety data. The trial is proceeding very well. It's even recruiting faster than anticipated.
And the overall concept is to wait until we have a given predefined number of events, of infection events, and then do a first evaluation if there's significant difference between vaccine and placebo group. And the number, the event number, so we will have several options, yeah, to evaluate different event numbers. Yeah? And based on that, based on the on lower event numbers, you might be able to file already in October. Yeah.
If the lower event numbers do not support a filing, we will have the opportunity to file four, six weeks later, based of course on the assumption that the trial is positive.
Speaker 8
Great, thanks for taking my questions.
Speaker 2
Yes, you're welcome.
Speaker 0
Your next question comes from the line of Arlinda Lee from Canaccord. Please ask your question.
Speaker 3
Congrats on all the progress. I had a couple of questions on 01/1962. One, can you provide an update on the enrollment of
Speaker 9
the pivotal trial? And two, I heard that some of the net costs for the trials have already given guidance that that was earlier in the development. So I'm wondering what do you think the cost might be for the remainder of the year? And then also on your oncology pipeline, I mean, more broadly, guess, the rapidity and efficiency with which you guys have taken once it's too into the clinic, I think highlights you guys' your platform. And I'm wondering what your appetite might be for additional collaborations and if you've been getting inbound interest.
Speaker 3
Thank you.
Speaker 2
So maybe we start with the first question. I had difficulties to acoustically understand the second and the third question. So the recruitment, my understanding is that the first question was related how fast the recruitment happens for the pivotal trial. So we anticipate to recruit up to 30,000 subjects until October. And we are at the moment, I can't tell you exact numbers, but pride is recruiting better than what was modeled.
So we are on track and even ahead. The second question can you repeat the second question a little bit louder?
Speaker 9
Yes. I'm just trying to, I guess, figure out on the cost sharing, how much you might accrue by year end.
Speaker 2
Is a Yes, question for
Speaker 5
yes. Yes, yes. I can take this one. Yes. So as I mentioned before, so the net cost the net share in our in this quarter for BERONTECH was €20,000,000 and this was majorly driven by clinical costs, also some preclinical research that was shared.
So let's call it, about a half or something was clinical costs. But remember, May and June was only the Phase I trial. So basically, patients were probably more expensive or sorry, subjects were more expensive, but also not as many. So I think you can do the math and upgrade it to like it would be a lot more expensive in Q3. And with the Q3 numbers, we'll also post like a better update.
But it will be, yes, triple digit million dollar amounts, I think.
Speaker 6
I mean maybe just to add to that one point, which is we had previously guided Arlinda to EUR 300,000,000 of spend for the year. And I think it's safe to say that we were tracking on that ex the Neon acquisition and the impact of COVID. So we've guided to EUR450 million to EUR600 million of net cash spend by the end of this year. So that delta there also gives you
Speaker 4
a sense
Speaker 6
for what the incremental amount could be.
Speaker 3
Great. Thank you.
Speaker 9
And then I guess the third question was, basically given, you guys wanted to kind of highlight the platform, I'm of curious about whether you've gotten, inbound interest and what your appetite might be for additional strategic collaborations.
Speaker 2
Maybe I can take the question. Yes, of course. This project, of course, validates our ability to respond quickly to challenges and opportunities. It validates our technology. It validates the safety of our approach.
And of course, it creates a lot of interest in future projects. And we are in discussion with our partners for additional opportunities coming up in 2021.
Speaker 6
Thank you.
Speaker 0
Your next question comes from the line of Sikuan Xu from Berenberg. Please ask your question.
Speaker 10
Hi, thank you. Good morning everyone. Congrats on the progress. So a few questions here on 162. I'd like to understand a little bit more on the older adults, the signals that you've seen in Phase one and two and maybe qualitative describe whether that's consistent with what people think the immune response there in this population is relatively lower than younger adults?
And then whether the results from B2 would be, B2 of any older adults would be included in the manuscript that you alluded that will be available in a few weeks?
Speaker 2
Yeah, so the first part of the question is older adults vaccine responses. So far as I know, there are no publications yet from any group about vaccine responses in elderly adults, but as everyone can guess, the immune response in elderly adults is weaker, yeah, and most likely for any vaccine platform, weaker. Reasons for that are twofold, the weaker innate immune response in elderly people, and the second is the reduced number of naive T cells and naive B cells in elderlies. What we have observed is that a dose which is fully effective to induce a strong antibody and T cell response in younger population is too low in the elderly population. That's the reason why we increased the dose yeah, for our candidate B2 and with the increase of the dose, we are well in the range of a fully effective immune response or what is expected to be a fully effective immune response.
And of course, yes, the data will be published with the next upcoming manuscript.
Speaker 10
Okay. And then do you have a plan to publish any results from other variants on C2?
Speaker 2
From other candidates?
Speaker 10
Yes, from other variants PROPHEase one two study. Yes,
Speaker 2
yes, yes. We we other variants are in continued clinical evaluation with a somehow lower priority. They expect to have a first publication related to another variant in October, yes, and we continue to share insights from this development program, which was not only just about selecting the first candidate, but selecting the best candidate and also generating insights into the future generation of vaccines which may come with lower doses, so that the lower doses might result in the same type of immune response.
Speaker 10
Great, that's helpful. Then finally just quickly touch on the oncology program BNT111. I remember there is an adjuvant cohort in the phase one study. The result haven't been communicated. Is there anything that you have seen in that adjuvant melanoma cohort?
Speaker 3
Thank you for that question. We are evaluating the adjuvant cohort as well and later this year we'll be able to report on that cohort as well.
Speaker 10
Okay, great. Thank you very much. Congrats on the progress.
Speaker 2
Thank you. Thank you.
Speaker 0
Your next question comes from the line of Dana Graybosch from SVB. Please ask your question.
Speaker 11
Thank you very much. Maybe I'll start with two on BNT162 and then after that come back for one on INAS. So on BNT162, two questions. One, there's been a lot made over differences in CD8 immunogenicity response between different companies and vaccines. And I wonder if you could comment on if there's anything in the BNT162 mRNA construct or lipid nanoparticle that could be driving your relatively higher CD8 response versus some of the others?
And then the second question is, we've seen some of the CD8 and CD4 T cell response data for patients who have COVID-nineteen. And in a lot of those publications, there's a lot of response against the nucleocapsid, especially for patients with certain HLA types. And I wonder what you think about your vaccines and others not including antigens for the nucleocapsid and whether that will be necessary in life cycle management for full protection for all people.
Speaker 2
Okay, so thanks Dana for the questions. So first of all, yes, yes, as you know, our focus in messenger RNA vaccine development is optimizing not only antibody responses, but particularly CD4 as well as CD8 responses. If you see the track record of the publications that we made in the last ten years, we have included a number of independent optimizations to increase the translation of our messenger RNA in human dendritic cells. This includes untranslated UTR regions, cap analogues, and as well as the delivery of the vaccine. The CD8 response requires a direct expression of the antigen in dendritic cells.
So if you express the protein outside of the dendritic cells, the classical pathway for antigen presentation is uptake of the antigen by the exogenous presentation machinery of the endotic cells and presenting on class two, which produce nice CD4 T cell responses. That's the reason why this recombinant protein vaccines and these vaccines which don't go into the endotic cells, you get CD4 T cell responses, but the only way to get powerful CD8 responses is expression, common expression in human endocytic cells, which we have proven for our platform and for the COVID-nineteen vaccine in retail. And I think this the key differentiator for observing a former CVA T cell response. The second part of the question was related, what was the second question?
Speaker 11
The nucleocapsid and whether there's
Speaker 12
some deficiency by not including it. Yeah,
Speaker 2
I think if you ask the question, what is the immunodominant antigen in an infection? This is not the same question with what antigen is particularly suitable to have a protective T cell response. Yes, a nucleoprotein is an immunodominant antigen, but we know that the virus entry is mediated of course by the full virus, and the spike protein is one key of proteins in this virus, and therefore having a protein, and particularly with a post spike protein, which is more than 1,200 amino acids, and a large protein with 1,200 amino acids gives you multiple base of presentation of class two and class one epitopes on multiple MXC haplotypes. So we believe that this spike protein is a near perfect antigen. We wanted clearly to avoid to add additional antigens into our vaccine, because every additional antigen comes with an independent price, yeah, an independent cost for potential diversification of the autoantibody repertoire, and therefore having a simple vaccine which is able to induce CD4 and CD8 T cells in a broad population of people is sufficient and we believe with this large spike protein, have an ideal candidate.
Speaker 11
That's very helpful. And then on INEST, looking back at the data that was presented at AACR, what are two questions? I wonder if we should read anything to the biomarkers that there were a few TCM cells versus TEM cells? And also whether the number of sort of immunogenic neoantigens at around 2.6 is high enough, and sort of with both of those biomarkers, if you're worried about them and if you're doing anything to optimize them as you go forward.
Speaker 2
Yeah, and so the most important learnings from this basket trial is the feasibility of the approach for really multiple different indications, the safety of the approach in different indications in combination also with Atezo and both immunogenicity. The shortcomings of the trials, of course, this is a bucket uncontrolled trial in patients with heavily pretreated and most of these patients had progression free survival time less than three months. And so this is not an ideal population for vaccine, and therefore it's difficult to draw any conclusions with regard to potential clinical activity from this cohort. And this was the reason why we have already started in 2019 our randomized trial in melanoma, in certain melanoma, which gives us with the PFS in range of above nine months gives us sufficient time to have a fully induced T cell response, vaccine induced T cell response. And here the key question is, if INS in combination with checkpoints located in a first line, a highly mutated tumor type could induce an added benefit.
So this trial would help us to ungate other indications with a similar type of profile. And the second learning, not only from this INAS trial, but also from the melanoma trial that we had published in 2017 and followed up with updated data in 2020 is that tumors with a lower tumor load might be the ideal setting for INS. And that's the reason why we are going to start two clinical trials in ttDNA positive tumors. One is the non small cell lung cancer program, and the second one is the colorectal cancer trial. And this is also based on a learning from the basket trial because in the colorectal cancer patient population that we have vaccinated, even though these were advanced patients, we observed really strong T cell responses, so that the number of mutations seems not to be the limiting for application of INF in this population, and that was encouraging enough to define these two additional indications.
So the next twelve months will extremely informative for the INEST project with data coming from the melanoma trial and with the randomized trials in lung cancer and colorectal cancer being active.
Speaker 11
Great, thank you very much.
Speaker 2
You're welcome.
Speaker 0
Your next question comes from the line of Nevin Jacob from UBS. Please ask your question.
Speaker 13
Hi, yes. Thank you for taking my question. Can you hear me okay?
Speaker 12
Yes.
Speaker 11
Perfect.
Speaker 13
Thanks. And if I could add quite a few if I may start with BNT162. Firstly, congrats on all the progress. Maybe I could just on the trial design, I just was hoping for some clarity on some of the statistical powering assumptions. What is the trial powered for, for what size, for what effect size?
And if you could provide any clarity on the number of events at the first interim look versus the second interim look, please? And then I have some follow-up questions.
Speaker 2
So these are really important questions, but at the moment, we are not able to share this information, But what you can, yeah, so what you can assume is that we have different interim readouts and this different interim readout, of course, come with different powers and with different assumptions about the efficacy. So that's how the trial is in general structured, but I can't share the actual numbers.
Speaker 13
Okay. And then maybe on the regulatory requirement, either based on an interim look and depending on the number of events, are the, are there different requirements associated with, say an interim look with 150 events versus 100 events? And attached to that, what is the regulatory requirement from a safety standpoint, a minimum follow-up of at least six months If you were to file in October, for example, based on an interim, would you have enough follow-up data as far as duration of safety that would allow for emergency use authorization?
Speaker 2
Yeah, so the safety aspect is addressed by two parameters. The one is the number of vaccinated subjects. Usually 3,000 subjects are sufficient to support a pandemic vaccine approval. The second is the follow-up time. And we are all aware that we have on the one side, the need to get a vaccine approved as fast as possible and make it available.
For example, we are an emergency use authorization pathway, yes, and on the other side to continue to collect the safety data. And that is exactly what is happening. So the subjects in this trial will be followed up for safety, safety parameters and get three months safety, six months safety and we'll continue also to monitor immune responses and the stability of immune response in the subject to understand also the durability of the immune response.
Speaker 13
And what exactly does emergency use authorization mean in the context of the vaccine? Does that mean it can be used if you have the doses, could that be used in a broad population or will it be only used in high risk populations such as patients in the frontline healthcare workers, so on and so forth? And then two quick other questions. You mentioned long term immunity. Wondering what gives you confidence or what are you seeing that should allow us to have some confidence in long term immunity or memory function?
And then on the Fosun partnership, it looks like you're moving forward with 16B1, if I'm correct, with Fosun and not 16B2. Maybe that's just earlier in where you're developing it in China, so maybe that's why. But if you could clarify that, that would be appreciated.
Speaker 2
Okay, so let's start with the first question, so who could benefit from an emergency use authorization? And of course, this is a issue of the governmental interest, Yeah, so this is something where the US government or the FDA has to decide for whom such a vaccine would applicable. That's same as in Europe. It's a decision of every government to make the vaccine available and to define to which population it should be made available. The second question or the third question was about durability.
So we are collecting data with regard durability of antibody response, as well as evaluation of the durability of T cell responses. So far we have published data for up to forty three days, and we will collect data for three months, six months, nine months, twelve months. We of course expect that the antibody titers will drop over time. That is what happened to antibody titers. This is vaccine independent.
We have to see how fast this drop is and what is the baseline level where the drop stops, and what kind of protection antibody based protection still happens at this baseline level. So this is something, which we will learn in the upcoming six months and continue to collect data. I'm confident that having a vaccine which comes with a combined immune response, CD4, CD8, as well as antibody response based on the collaboration of this immune system arms, will require lower amounts of each component since we will have a synergistic activity. But actually the community, the whole scientific community and the industry has to learn what happens in the next two years, how stable are these immune responses, what is required to protect from reinfection? If this is an issue, if the drop of the immune response is an issue, I believe with the messenger RNA vaccine we are in a good place to implement a booster immunization because this is one of the key strengths of messenger RNA vaccines.
You can really use it several times for boosting the immune response. It is not limited by any type of backbone immune response which limits the activity of inducing and boosting antibody and T cell response.
Speaker 13
Thank you so much. And just maybe two very quick questions on fixed VAC. The T cell data in the Nature publication certainly look interesting,
Speaker 6
but it
Speaker 13
is plasma data. Wondering if what it looks like in the tumor microenvironment, which as you know, literature suggests there's better correlation with anti tumor activity with tumor T cells, T cells in the tumor. And then wondering also when we're going to see the next dataset with a later cutoff point from this phase one?
Speaker 2
Yeah, first of all, have done in other studies, we analyze tumor tissue and presence of T cell receptors of vaccine induced T cell receptors, for example, in the INF trial, but also for the fixed back and we confirm that T cells that have been observed in the peripheral blood indeed infiltrate into the tumor and are detectable in the tumor. So this was not required to repeat that in this special publication, which was more about the relationship between the strengths and duration of the immune responses and the function of the immune response to cytotoxic function. The next publication from this study will be sometime in 2021. I assume it's the second more the 2021 with regard to the population in this trial, which is evaluated for the last week survival. So we had a patient population which who did not have tumors, metastatic tumor lesions, but had surgery and afterwards received the therapy and we will have relapsed free survival data here.
And actually the next upcoming publication would be the publication describing the Phase two data. So we are, as you know, are going to start a randomized Phase two study in melanoma six pack end of this year. And it will be a relatively small study, which will recruit within the next eighteen to twenty four months. And I hope that this will be paid the pivotal data required for registration of Pixabag in second line plus melanoma.
Speaker 13
Got it, I'm sorry, the question on Flosun, are you moving forward with 162B1 with them or six b two? No.
Speaker 2
Know, add them because you can
Speaker 12
Yes.
Speaker 3
Sure. We we are moving forward with b two globally, also also in China and with Fosun. The reason why the B1 part of the study or testing in China has started basically at the same time when we made the B2 decision is that we think that it has value to also compare in the Chinese population, meaning in other population, these two candidates of MOD RNA platform and we are now preparing the B2 entry in China. So, the regulatory processes are a bit different there. It's the most sequential approach, not the umbrella trial approach, which works in that regulatory region.
We think that generating class intrinsic data for MOD RNA as such and also benchmarking these two, B1 and B2 mod RNAs against each other in the Chinese population is of value for the entire program.
Speaker 13
That's very clear. Thank you very much for this call. Very helpful details and congrats on the progress.
Speaker 3
Thank you.
Speaker 0
Your next question comes from the line of Suzanne Van Vostersen from Kempen. Please ask your question.
Speaker 14
Hi, good afternoon. I have a question, on the COVID-nineteen vaccine. Looking back at the four different candidates that you went into phase one with originally, I was just wondering, for B1 and B2, these are mRNAs. It is our understanding that this format is more often used by BioNTech to de immunize mRNA to make it especially useful for immune silent applications. So can you elaborate a bit, you know, are B1 and B2 also uridine modified or how are they modified to be more immunogenic?
Speaker 2
Yeah, so rationale for starting with four different vaccine was on the one hand to evaluate our three different vaccine platforms. This is the nucleoside modified messenger RNA platform, were now used for the candidate B1 and B2, and here B1 and B2 were selected based on the experience of the field in the past with MERS and with SARS, where both antigens had been evaluated but never benchmarked side by side. It's RBD and the Yeah, the RBD and the spike. And our study shows that both candidates are viable candidates with B2 having some advantage in this case. For the second platform, the Uridine based platform, which comes with the potential advantage of a higher reactogenicity, and thereby stronger activity at low doses.
We started to the RBD variant and generated some data and the data showed that we have immunogenicity, but the immunogenicity does not match the immunogenicity that we have observed with the nucleoside modified mRNA. And the second was the fourth candidate was the siRNA based candidate, and here we had in the preclinical models evaluated RBD as well as full spike and determined that the full spike for the self amplifying mRNA is significantly better. So only the full spike is currently evaluated and here we expect immunogenicity data since this is a really dose escalation study started with extremely low doses, yeah, we expect the first relevant immunogenicity data in the timeframe September, and we'll share that with the community. So the Fab amplifying messenger RNA comes with the potential promise of having a potent vaccine candidate, which comes with doses at lower, in the low microgram range.
Speaker 14
Got it, got it. And then maybe on the phase two, three trial, in terms of the primary endpoints, can you remind us of the bar that you have to achieve? Was that a fifty percent reduction in infection rates? Do you need to hit both co primary endpoints or one of
Speaker 1
the two to claim success?
Speaker 2
Yeah, it's very simple. We stick to the guidance of the FDA, yeah, and that's the lowest one.
Speaker 14
And are the co primary endpoints, are they either or or are they and that you need to achieve to claim?
Speaker 3
These are either or.
Speaker 14
Okay. And maybe just one follow-up in this regard, just to clarify for the filing. Is the primary endpoint data the hard requirement or maybe for an emergency use authorization, Will there be immunogenicity data analyzed with the interim analysis? Could it be that you can file on that if your primary endpoint data is trending in the right direction for example, or is it a hard requirement?
Speaker 2
So this is an ongoing discussion with the FDA, I think the FDA was crystal clear when it announced in July the requirements for authorization. And if this is still the case, then we would expect that use of the vaccine is only allowed when there are efficacy data around.
Speaker 14
Got it. All right. Thanks a lot.
Speaker 0
Your final question comes from the line of Olga Smolensava from Bryan Garnier. Please ask your question.
Speaker 12
Good afternoon, everyone, and thank you for taking my questions. Firstly, on BNT162, considering that recent publications suggested that different mutations in spike protein could provide different immunogenicity. Could you maybe give us a little bit more color on the sort of optimization of the full spike antigen in B2? What kind of mutations in spike protein includes?
Speaker 2
Yeah, so we, this is the public, we used the P2 stabilized, pre fusion stabilized mutation of the spike protein, which has been described to use as trauma antibody response as compared to the wild type protein.
Speaker 12
Okay, that's great, thanks. And maybe just a little bit on BNT221. So how should we think about target population here in terms of differentiation with the planned potential pivotal BNT111
Speaker 4
program?
Speaker 11
Sorry. I didn't get that.
Speaker 3
Is this BNT one 11?
Speaker 12
Sorry. It's on BNT221?
Speaker 2
221.
Speaker 6
The the Neon program.
Speaker 12
Neon program. Okay.
Speaker 3
Okay. Okay. The neon program. You you you mean the the adoptive p cell therapy program, which which is
Speaker 12
just about to to start? Yes. Yes. I'm just interested in the target population here Yeah. Because it seems to overlap with b n t one one one.
And I'm just thinking how you yeah. Sorry.
Speaker 2
Yeah. So the trial which is going to start in Europe will be relapsing melanoma, metastatic melanoma patients. And so this is more or a proof of concept study because the approach is really elegant, it is an approach of creating a neoantigen specific T cells directly from blood, So this is in principle a universal approach applicable to any type of tumor and the colleagues from BioNTech U. S. Have generated data also for other type of solid cancer, But melanoma is of course an excellent tumor type for a proof of concept study.
Speaker 12
Okay, great, thank you. And many congratulations on all the progress.
Speaker 2
Thank you.
