First quarter2021 and subsequentupdates

Infectious disease

COVID-19 vaccine program – BNT162b2

In March 2021, BioNTech announced its Full Year 2020 Financial Results and Corporate Update as a part of the Annual Report filed on Form 20-F, highlighting developments relating to its COVID-19 vaccine program between January 1 and March 30, 2021 (Link to press release). A summary of these developments as well as full details of subsequent developments that occurred after March 30, 2021 is provided below.

1

As of May 6, 2021 BioNTech and Pfizer have shipped approximately 450 million doses of BNT162b2 to 91 countries and territories around the world.

To date, the companies have signed orders of approximately 1.8 billion doses for delivery in 2021, and they have also signed the first contracts for 2022 and beyond. Further discussions for additional dose commitments are ongoing for 2021 and beyond. BioNTech expects BNT162b2 annual manufacturing capacity to reach 3 billion doses by the end of 2021, and expects to have capacity to manufacture more than 3 billion doses in 2022.

Multiple clinical trials are ongoing to expand the authorization of BNT162b2 to additional population groups, such as children from 6 months to 11 years of age, and to collect further data in healthy pregnant women.

To date, there is no evidence that an adaptation of BioNTech’s current COVID-19 vaccine against key identified emerging variants is necessary. Despite this, BioNTech has developed a comprehensive strategy to address these variants should the need arise in the future. As part of BioNTech’s strategy to contend with the variant challenge, BioNTech submitted to the U.S. Food and Drug Administration (FDA), and the FDA has approved an additional amendment to the study protocol of the global Phase 1/2/3 trial which includes: (1) an assessment of the impact of a third dose of BNT162b2 in prolonging immunity against COVID-19 and in protecting against COVID-19 caused by potential newly emerging SARS-CoV-2 variants, and (2) an assessment of a modified, variant-specific version of BNT162b2. The aim of this study is to explore the regulatory pathway that BioNTech and Pfizer would pursue if SARS-CoV-2 were to change enough to require an updated vaccine. This trial started in March 2021.

In the first quarter of 2021, BioNTech also advanced its work to broaden access through improvements to its cold chain distribution systems and processes. Both the FDA and the European Medicines Agency (EMA) have approved the transportation and storage of undiluted frozen vials of BNT162b2 at temperatures (-20°C) commonly found in pharmaceutical freezers for a period of up to two weeks. Further stability data have been assessed and formulation optimization activities are ongoing, including a study to evaluate a lyophilized (or freeze-dried) and a ready-to-use formulation of BNT162b2.

BNT162b2 clinical development updates

• On March 31, 2021, BioNTech and Pfizer announced that BNT162b2 demonstrated 100% efficacy and robust antibody responses in a Phase 3 trial in adolescents aged 12 to 15 with or without prior evidence of SARS-CoV-2 infection. The trial enrolled 2,260 adolescents in the United States. In the trial, 18 cases of COVID-19 were observed in the placebo group (n=1,129) versus none in the vaccinated group (n=1,131). Vaccination with BNT162b2 elicited high SARS-CoV-2 neutralizing antibody titers, demonstrating strong immunogenicity in a subset of adolescents one month after the second dose. BNT162b2 administration was generally well tolerated.

• On March 31, 2021, BioNTech and Pfizer began evaluating the administration of a single booster dose five to seven months after receiving the second dose of BNT162b2. To demonstrate duration of protection, and protection against the emerging variants of concern, an additional dose of BNT162b2 or of BNT162b2_SA (encoding for the spike protein of the variant B.1.351) is being given to about 600 Phase 3 participants. About 30 participants that received BNT162b2_SA will be given another dose of BNT162b2_SA.

2

A new cohort of approximately 300 participants will be enrolled who are COVID-19 vaccine-naïve (i.e., including BNT162b2-naïve) and have not been infected withCOVID-19. They will receive BNT162b2_SA given as a two-dose series, separated by 21 days. The objective of this Phase 1/2/3 protocol amendment is to describe the safety and tolerability profile of BNT162b2_SA, to evaluate its non-inferiority compared to BNT162b2, and to analyze the immune response generated by BNT162b2_SA. By evaluating BNT162b2_SA as a prototype vaccine, the companies aim to inform the development of an efficient regulatory pathway for testing future modified mRNA vaccines, using the current pathways for flu vaccines as models(blueprint study).

• On April 1, 2021, BioNTech and Pfizer announced updated topline results confirming high efficacy and no serious safety concerns through up to six months following the second dose. Topline efficacy was based on an analysis of 927 confirmed symptomatic cases of COVID-19 observed in the pivotal Phase 3 study through March 13, 2021. BNT162b2 was 91.3% effective against COVID-19, measured seven days through up to six months after the second dose. The vaccine was also 100% effective against severe disease, as that term is defined by the U.S. Centers for Disease Control and Prevention, and 95.3% effective against severe COVID-19 as that term is defined by the FDA. Safety data collected from more than 12,000 vaccinated participants who had a follow-up time of at least six months after the second dose demonstrated a favorable safety and tolerability profile.

In an additional exploratory analysis of 800 trial participants enrolled in South Africa, where the B.1.351 lineage is prevalent, nine cases of COVID-19 were observed, all in the placebo group, indicating vaccine efficacy of 100%. Of these cases, eight were of the B.1.351 lineage, confirming efficacy against B.1.351 virus. These data support previous results from immunogenicity studies demonstrating that BNT162b2 induced a robust neutralizing antibody response to the B1.351 variant and, although lower than to the wild-type strain, it does not appear to affect the observed high efficacy against COVID-19 caused by this variant, as published in the New England Journal of Medicine.²

• On April 1, 2021, BioNTech and Pfizer started a Phase 3, randomized, observer-blind study to evaluate the safety, tolerability, and immunogenicity of multiple formulations of BNT162b2, administered on a two-dose (separated by 21 days) schedule in adults aged 18 to 55. Part 1 of the study is comparing the safety and tolerability of lyophilized (or freeze-dried) BNT162b2 to the current frozen-liquid formulation of BNT162b2 and is evaluating non-inferiority of the immune response. Part 2 of the study will evaluate the safety and immunogenicity of a ready-to-use formulation of BNT162b2, and will be initiated in May 2021. The study, which is being conducted in the United States, will enroll approximately 610 participants. BioNTech and Pfizer expect to obtain results from both study parts in the third quarter of 2021.

Regulatory updates

• On April 9, 2021, BioNTech and Pfizer requested amendments to the U.S. Emergency Use Authorization to expand the use of BNT162b2 to adolescents aged 12 to 15.

3

• On April 30, 2021, BioNTech and Pfizer submitted to EMA a variation to the European Conditional Marketing Authorization (CMA) for COMIRNATY^® to request an extension of the indication for use in adolescents 12 to 15 years of age. If EMA approves the variation, the amended CMA will be valid in all 27 member states of the European Union. 

• On April 30 and May 4, 2021, BioNTech and Pfizer submitted new stability data of BNT162b2 to the FDA and EMA in order to update the product’s label to extend the storage at standard refrigerator temperatures of 2°C to 8°C to four weeks.

• On May 5, 2021, BioNTech and Pfizer Canada announced that Health Canada has expanded the Interim Order authorization for BNT162b2 to include individuals 12 to 15 years of age. This is the first COVID-19 vaccine authorized in Canada for use in this age group.

• On May 7, 2021, BioNTech and Pfizer announced the initiation of a Biologics License Application (BLA) with the FDA for approval of BNT162b2 to prevent COVID-19 in individuals 16 years of age and older. Data to support the BLA will be submitted by the companies to the FDA on a rolling basis over the coming weeks, with a request for Priority Review. BioNTech is the Marketing Authorization Holder in the European Union, and the holder of emergency use authorizations or equivalent in the United States (together with Pfizer), United Kingdom, Canada and other countries in advance of a planned application for full marketing authorizations in these countries.

Commercial updates

• On April 19, 2021, BioNTech and Pfizer announced an agreement with the European Commission (EC) to supply an additional 100 million doses of its COVID-19 vaccine, as a result of the EC’s decision to exercise its option. The total number of doses to be delivered to the European Union by the end of 2021 is now 600 million.

• In April 2021, Pfizer and BioNTech entered into an agreement with Israel to supply several million doses in 2022, with an option to purchase additional doses. The companies also entered into an agreement with Canada to supply up to 125 million doses in 2022 and 2023, with options to purchase up to 60 million additional doses in 2024. Discussions for additional dose commitments with governments and territories worldwide are also ongoing for 2021 and beyond.

• On May 6, 2021, BioNTech and Pfizer announced that they have signed a Memorandum of Understanding with the International Olympic Committee to donate doses of COVID-19 Vaccine to help vaccinate athletes, and their delegations, participating in the Olympic and Paralympic Games Tokyo 2020, which are scheduled to take place in July 2021.

• On May 7, 2021, the European Commission (EC) announced that BioNTech and Pfizer plan to supply the EC with 900 million doses of COMIRNATY^®, the Companies’ COVID-19 vaccine, to the 27 European Union (EU) member states beginning December 2021 through 2023, with an option for the EC to request up to an additional 900 million doses. This contract is expected to close upon final confirmation by the EC.

Manufacturing updates

• BioNTech expects capacity to reach up to 3 billion doses by end of 2021, and expects to have capacity to manufacture more than 3 billion doses in 2022.

• In March 2021, EMA approved the manufacturing of BioNTech’s COVID-19 vaccine drug product at its facility in Marburg, Germany. This manufacturing facility is one of the largest mRNA vaccine manufacturing sites worldwide with an annual production capacity of up to one billion doses of COVID-19 vaccine, once fully operational. The first batches of vaccines manufactured at the Marburg facility were delivered in mid-April.

• BioNTech plans to deliver up to 250 million doses of BNT162b2 in the first half of 2021.

Oncology

BioNTech is accelerating the development of a broad oncology pipeline, which has now advanced 14 product candidates in 15 ongoing trials. In April 2021 the Company started a first-in-human Phase 1 trial for the T cell therapy, targeting personalized neoantigens, named BNT221. Additional important milestones in the advancement of BioNTech’s immuno-oncology pipeline in the first quarter of 2021 included the initiation of first-in-human trials for CARVac (BNT211) and RiboCytokines (BNT151). BioNTech also expects to further advance its oncology pipeline in 2021 with up to three additional programs expected to move into randomized Phase 2 trials. Additionally, three preclinical programs are expected to move into Phase 1 trials in the second half of 2021.

During the remainder of 2021, BioNTech expects at least four data updates from its ongoing clinical trials.

mRNA programs

FixVac

• BNT111 – In collaboration with Regeneron, a randomized Phase 2 trial for the treatment of patients with advanced melanoma progressing during or after prior therapy with a PD-1 inhibitor, utilizing a combination of BNT111 and Regeneron and Sanofi’s Libtayo^® (cemiplimab) is planned to start in the first half of 2021.

• BNT113 – A Phase 2 trial evaluating BNT113 in combination with pembrolizumab versus pembrolizumab monotherapy as a first-line treatment in patients with unresectable recurrent or metastatic HPV16+ head and neck squamous cell carcinoma (HNSCC) expressing PD-L1, is planned to start in the first half of 2021 in the United States and the European Union. BNT113 has not been combined with anti-PD1 before and the Phase 2 trial will start with a run in portion designed to demonstrate the safety of the combination of BNT113 and pembrolizumab. These data are required to address the partial clinical hold on the subsequent randomized part of the Phase 2 trial.

Individualized neoantigen specific immunotherapy (iNeST)

• BNT122 (Autogene Cevumeran) – BioNTech’s iNeST product candidate is partnered with Genentech.

5

For the adjuvant treatment of colorectal cancer, first patient dosing in a randomized Phase 2 trial in circulating tumor DNA positive, surgically resected Stage 2 (high risk)/Stage 3 colorectal cancer is now planned in the second half of 2021.

RiboCytokines

• BNT151 – A Phase 1/2a dose escalation trial evaluating BNT151 with expansion cohorts in multiple solid tumor indications is ongoing.

• BNT152+153 – BioNTech plans to start a Phase 1 trial for BNT152 (encoding IL-7) plus BNT153 (encoding IL-2) in multiple solid tumors in the first half of 2021.

RiboMabs

• BNT141 – In February 2021, the FDA approved the IND for a Phase 1 first-in-human clinical trial for BNT141. BioNTech plans to start the trial in the second half of 2021.

• BNT142 – BioNTech plans to start a Phase 1 clinical trial for BNT142 in the second half of 2021.

Antibodies

Next-generation checkpoint immunomodulators

BNT311 and BNT312 are partnered with Genmab.

• BNT311/GEN1046 – A Phase 1/2a dose escalation trial with multiple expansion cohorts in patients with malignant solid tumors is ongoing. A data update for the trial is planned in the second half of 2021.

• BNT312/GEN1042 – A Phase 1/2a dose escalation trial with expansion cohorts in patients with solid tumors is ongoing. The first data disclosure for the trial is planned in the second half of 2021.

Cell therapies

CAR-T cell immunotherapy

• BNT211 – A first-in-human Phase 1/2a open-label, multi-center dose escalation and dose expansion basket trial of BNT211 with Claudin-6 CAR-T cells as monotherapy, or in combination of Claudin-6 CAR-T cells with Claudin-6 CARVac, is ongoing. The trial is enrolling patients with CLDN6-positive relapsed or refractory advanced solid tumors including ovarian, testicular, lung, gastric and endometrial cancers. The combination of CLDN6 CAR-T cell immunotherapy and CARVac is expected to improve expansion and persistence of CLDN6 CAR-T.

BioNTech plans to present early data from the ongoing BNT211 Phase 1/2a trial on three patients treated with a starting dose of CLDN6 CAR-T cells at the upcoming 18th Association for Cancer Immunotherapy (CIMT) Annual Meeting 2021. In these heavily pretreated patients with solid tumors, neither acute nor dose-limiting toxicities were observed and all adverse events were transient and mild to moderate. Robust CAR-T cell engraftment could be detected in all three patients, as well as early signs of clinical activity. Following completion of the first dose level with CAR-T cell monotherapy, the trial is now progressing to the next dose level and a combination treatment involving CAR-T cells with an RNA vaccine, which BioNTech refers to as CARVac. A data update is planned in the second half of 2021.

6

Neoantigen-targeting T cell therapy

• BNT221 – In April 2021, the first patient was dosed in a first-in-human Phase 1 dose escalation trial for the treatment of metastatic melanoma in patients who are refractory or unresponsive to checkpoint inhibitors. Part 1 consists of the monotherapy dose escalation of BNT221. In part 2, BNT221 will be added to anti-PD1 after first-line therapy. The primary objectives of the trial are to evaluate the safety and feasibility of administering BNT221, in addition to an evaluation of immunogenicity and clinical efficacy.

BNT221 (NEO-PTC-01) is a personal neoantigen-targeted T cell therapy candidate derived from patients’ peripheral blood cells. The product candidate consists of multiple CD8+ and CD4+ T cell populations targeting multiple selected neoantigens unique to each patient's tumor. The proprietary stimulation process allows for the induction of T cells from the naïve, as well as expansion of T cells from the memory compartment.

Small molecule immunomodulators

Toll-like receptor binding agonist

• BNT411 – A Phase 1/2a dose-escalation trial of BNT411 as a monotherapy in patients with solid tumors, and in combination with atezolizumab, carboplatin and etoposide in patients with chemotherapy-naïve extensive-stage small cell lung cancer (ES-SCLC) is ongoing. A data update from this trial is planned in the second half of 2021.

Corporate development

• On May 9, 2021, BioNTech agreed the heads of terms with Fosun Pharma to establish a 50/50 Joint Venture (JV) to manufacture the COVID-19 vaccine in Mainland China. The establishment of a JV will be conditional on BioNTech receiving approval for its COVID-19 vaccine in Mainland China and agreement with Fosun Pharma on a definitive JV agreement, in addition to other conditions. As part of its global supply strategy, BioNTech believes that establishing local manufacturing capacity for the COVID-19 vaccine could substantially increase the Company’s ability to supply vaccines to China upon approval.  

• On May 10, 2021, BioNTech announced plans to expand its global footprint to Asia with the establishment of its first regional headquarters for southeast Asia in Singapore. In addition to selecting Singapore as its future regional headquarters, BioNTech plans to establish a fully integrated mRNA manufacturing facility in Singapore with support from the Singaporean Economic Development Board (EDB). The new facility will leverage cutting-edge manufacturing and digital infrastructure and will be equipped to produce a range of novel mRNA vaccines and therapeutics. The envisioned site will bring highly automated and end-to-end mRNA production capabilities. The facility, with an estimated annual capacity of several hundred million doses, will provide regional and global supply capacity, as well as a rapid response capability for southeast Asia to address potential pandemic threats. BioNTech plans to open its Singapore office and initiate construction of the manufacturing facility in 2021, subject to planning approval, and anticipates the site could be operational as early as 2023.

Safety Information AUTHORIZED USE IN THE U.S.: The Pfizer-BioNTech COVID19 Vaccine is authorized for use under an Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 16 years of age and older. IMPORTANT SAFETY INFORMATION FROM U.S. FDA EMERGENCY USE AUTHORIZATION PRESCRIBING INFORMATION: Do not administer Pfizer-BioNTech COVID-19 Vaccine to individuals with known history of a severe allergic reaction (e.g., anaphylaxis) to any component of the Pfizer-BioNTech COVID-19 Vaccine. Appropriate medical treatment used to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of Pfizer- BioNTech COVID-19 Vaccine. Monitor Pfizer-BioNTech COVID-19 Vaccine recipients for the occurrence of immediate adverse reactions according to the Centers for Disease Control and Prevention guidelines (https://www.cdc.gov/vaccines/covid-19/). Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to the Pfizer-BioNTech COVID-19 Vaccine. The Pfizer-BioNTech COVID-19 Vaccine may not protect all vaccine recipients. In clinical studies, adverse reactions in participants 16 years of age and older included pain at the injection site (84.1%), fatigue (62.9%), headache (55.1%), muscle pain (38.3%), chills (31.9%), joint pain (23.6%), fever (14.2%), injection site swelling (10.5%), injection site redness (9.5%), nausea (1.1%), malaise (0.5%), and lymphadenopathy (0.3%). Severe allergic reactions, including anaphylaxis, have been reported following the Pfizer-BioNTech COVID-19 Vaccine during mass vaccination outside of clinical trials. Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of the Pfizer-BioNTech COVID-19 Vaccine. Available data on Pfizer-BioNTech COVID-19 Vaccine administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy. Data are not available to assess the effects of Pfizer-BioNTech COVID-19 Vaccine on the breastfed infant or on milk production/excretion. There are no data available on the interchangeability of the Pfizer-BioNTech COVID-19 Vaccine with other COVID-19 vaccines to complete the vaccination series. Individuals who have received one dose of Pfizer-BioNTech COVID-19 Vaccine should receive a second dose of Pfizer-BioNTech COVID-19 Vaccine to complete the vaccination series. Vaccination providers must report Adverse Events in accordance with the Fact Sheet to VAERS at https://vaers.hhs.gov/reportevent.html or by calling 1-800-822-7967. The reports should include the words "Pfizer-BioNTech COVID-19 Vaccine EUA" in the description section of the report. Vaccination providers should review the Fact Sheet for Information to Provide to Vaccine Recipients/Caregivers and Mandatory Requirements for Pfizer-BioNTech COVID-19 Vaccine Administration Under Emergency Use Authorization.
