BNT162b2 FDA Approval Status

FDA Approved: No
Brand name: BNT162b2
Generic name: SARS-CoV-2 vaccine
Company: Pfizer Inc. and BioNTech SE
Treatment for: Prevention of COVID-19

BNT162b2 is an investigational mRNA vaccine against SARS-CoV-2 in development for the prevention of COVID-19. To date there have been no mRNA vaccines licensed for use in humans.

  • The BNT162 program initially consisted of four vaccine candidates, each representing a unique combination of messenger RNA (mRNA) format and target antigen. In early studies, BNT162b1 and BNT162b2 emerged as the two strongest candidates based on assessments of safety and favorable viral antigen specific CD4+ and CD8+T cell responses.
  • BNT162b1 is a nucleoside modified RNA (modRNA) that encodes an optimized SARS-CoV-2 receptor-binding domain (RBD) antigen, and BNT162b2 is a nucleoside modified RNA (modRNA) that encodes an optimized SARS-CoV-2 full-length spike glycoprotein (S), which is a target of virus neutralizing antibodies.
  • In Phase 1 studies, BNT162b1 and BNT162b2 elicited similar dose-dependent SARS-CoV-2–neutralizing antibody geometric mean titers, which were substantially elevated after the second dose, showing clear benefit of a two-dose regimen.
  • The data demonstrated a favorable overall tolerability profile for BNT162b2 when compared to BNT162b1. After Dose 1, systemic events reported by participants 65 to 85 years old who received BNT162b2 were similar to those reported by those who received placebo. After Dose 2 of 30μg BNT162b2, only 17% of participants 18 to 55 years old and 8% of participants 65 to 85 years old reported fever (≥38.0 to 38.9 °C), compared to 75% of 18 to 55 year old participants and 33% of 65 to 85 year old participants administered a second dose of 30μg of BNT162b1. Severe systemic events (fatigue, headache, chills, muscle pain, and joint pain) were reported in small numbers of younger BNT162b2 recipients and were transient and manageable. No severe systemic events were reported by older BNT162b2 recipients. There were no reports of Grade 4 systemic events by any BNT162 recipient.
  • The BNT162b2 vaccine candidate was chosen to progress into the Phase 2/3 study, at a 30 µg dose level in a two-dose regimen, based on the data from preclinical and clinical studies.
  • BNT162b2 was granted U.S. FDA Fast Track designation in July 2020.
  • The Phase 2/3 safety and efficacy study is an event-driven trial that includes up to 44,000 participants aged between 16 and 85 years of age from diverse population groups in the U.S., Argentina and Brazil. Additional enrollment is planned in Germany, Turkey and South Africa.
  • The first results from an interim efficacy analysis of a Phase 3 study were reported by Pfizer on November 9, 2020. BNT162b2 was found to be more than 90% effective in preventing COVID-19 in participants without evidence of prior SARS-CoV-2 infection. Protection is achieved 28 days after the initiation of the vaccination, which consists of a 2-dose schedule (injections of the vaccine on Day 1 and Day 21). The study is ongoing and additional data could affect these results.
  • The analysis evaluated 94 confirmed cases of COVID-19 in trial participants. The trial is continuing to enroll and is expected to continue through the final analysis when a total of 164 confirmed COVID-19 cases have accrued. The study will also evaluate the potential for the vaccine candidate to provide protection against COVID-19 in those who have had prior exposure to SARS-CoV-2, as well as vaccine prevention against severe COVID-19 disease.
  • Along with the efficacy data generated from the clinical trial, Pfizer and BioNTech are working to prepare the necessary safety and manufacturing data to submit to the FDA to demonstrate the safety and quality of the vaccine product produced. Pfizer and BioNTech plan to submit data from the full Phase 3 trial for scientific peer-review publication.
