Pfizer and BioNTech Dose First US Participants for BNT162 COVID-19 Vaccine Program

Pfizer Inc. (New York, NY, USA) and Biopharmaceutical New Technologies {(BioNTech) Mainz, Germany} have dosed the first participants in the US in the Phase 1/2 clinical trial for the BNT162 vaccine program to prevent COVID-19.

The trial is part of a global development program, and the dosing of the first cohort in Germany was completed last week. The Phase 1/2 study is designed to determine the safety, immunogenicity and optimal dose level of four mRNA vaccine candidates evaluated in a single, continuous study. The dose level escalation portion (Stage 1) of the Phase 1/2 trial in the US will enroll up to 360 healthy subjects into two age cohorts (18-55 and 65-85 years of age). The first subjects immunized in Stage 1 of the study will be healthy adults 18-55 years of age. Older adults will only be immunized with a given dose level of a vaccine candidate once testing of that candidate and dose level in younger adults has provided initial evidence of safety and immunogenicity. During the clinical development stage, BioNTech will provide clinical supply of the vaccine from its GMP-certified mRNA manufacturing facilities in Europe.

BioNTech and Pfizer will work jointly to commercialize the vaccine worldwide upon regulatory approval (excluding China, where BioNTech has a collaboration with Fosun Pharma for BNT162 for both clinical development and commercialization). Pfizer and BioNTech are working to scale up production for global supply. Pfizer-owned sites in three US states and in Belgium have been identified as manufacturing centers for COVID-19 vaccine production, with more sites to be selected. Through its existing mRNA production sites in Germany, BioNTech plans to ramp up its production capacity to provide further capacities for a global supply of the potential vaccine. The breadth of this program should allow production of millions of vaccine doses in 2020, increasing to hundreds of millions in 2021.

“With our unique and robust clinical study program underway, starting in Europe and now the US, we look forward to advancing quickly and collaboratively with our partners at BioNTech and regulatory authorities to bring a safe and efficacious vaccine to the patients who need it most. The short, less than four-month timeframe in which we’ve been able to move from pre-clinical studies to human testing is extraordinary and further demonstrates our commitment to dedicating our best-in-class resources, from the lab to manufacturing and beyond, in the battle against COVID-19,” said Albert Bourla, Chairman and CEO, Pfizer.

“It is encouraging that we have been able to leverage more than a decade of experience in developing our mRNA platforms to initiate a global clinical trial in multiple regions for our vaccine program in such a short period. We are optimistic that advancing multiple vaccine candidates into human trials will allow us to identify the safest, most effective vaccination options against COVID-19,” said CEO and Co-founder of BioNTech, Ugur Sahin.
