Pfizer and BioNTech Announce Early Positive Data from an Ongoing Phase 1/2 study of mRNA-based Vaccine Candidate Against SARS-CoV-2

NEW YORK & MAINZ, Germany–(BUSINESS WIRE)– Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced preliminary data from the most advanced of four investigational vaccine candidates from their BNT162 mRNA-based vaccine program, Project Lightspeed, against SARS-CoV-2, the virus causing the current global pandemic. The BNT162 program is evaluating at least four experimental vaccines, each of which represents a unique combination of mRNA format and target antigen. The manuscript describing the preliminary clinical data for the nucleoside-modified messenger RNA (modRNA) candidate, BNT162b1, which encodes an optimized SARS-CoV-2 receptor binding domain (RBD) antigen, is available on an online preprint server at https://www.medrxiv.org/content/10.1101/2020.06.30.20142570v1 and is concurrently undergoing scientific peer-review for potential publication. Overall, the preliminary data demonstrated that BNT162b1 could be administered in a dose that was well tolerated and generated dose dependent immunogenicity, as measured by RBD-binding IgG concentrations and SARS-CoV-2 neutralizing antibody titers.
