Pfizer and BioNTech Provide Update on Ongoing Studies of COVID-19 Vaccine
NEW YORK and MAINZ, GERMANY, DECEMBER 17, 2021 — Pfizer Inc. (NYSE: PFE) and
BioNTech SE (Nasdaq: BNTX) today shared that following a routine review by the external independent Data Monitoring Committee (DMC), the companies will amend the clinical study evaluating the safety, tolerability, and immunogenicity of the Pfizer-BioNTech COVID-19 Vaccine in children 6 months to under 5 years of age. The study will now include evaluating a third dose of 3 µg at least two months after the second dose of the two-dose series to provide high levels of protection in this young age group.
While the study is ongoing and remains blinded, a pre-specified immunogenicity analysis was conducted on a subset of the study population one month following the second dose. Compared to the 16- to 25-year-old population in which high efficacy was demonstrated, non-inferiority was met for the 6- to 24-month-old population but not for the 2- to under 5-year-old population in this analysis. No safety concerns were identified and the 3 µg dose demonstrated a favorable safety profile in children 6 months to under 5 years of age.
The decision to evaluate a third dose of 3 µg for children 6 months to under 5 years of age reflects the companies’ commitment to carefully select the right dose to maximize the risk-
benefit profile. If the three-dose study is successful, Pfizer and BioNTech expect to submit data to regulators to support an Emergency Use Authorization (EUA) for children 6 months to under 5 years of age in the first half of 2022.
Pfizer and BioNTech also plan to evaluate a third dose of the 10 µg formulation in children 5 to under 12 years of age.
Furthermore, the companies have initiated a low dose sub-study of a third dose of 10 µg or 30 µg in approximately 600 adolescents aged 12- to 17, to assess safety and immunogenicity.
These updates were informed by the effectiveness data for three doses of the vaccine for people 16 years and older, and the early laboratory data observed with Delta and other variants of concern, including Omicron, which suggest that people vaccinated with three doses of a COVID- 19 vaccine may have a higher degree of protection.
These changes have been endorsed by and agreed upon with the U.S. Food and Drug Administration.
About the Phase 1/2/3 Trial in Children
The Phase 1/2/3 trial initially enrolled up to 4,500 children ages 6 months to under 12 years of age in the United States, Finland, Poland, and Spain from more than 90 clinical trial sites. It was
designed to evaluate the safety, tolerability, and immunogenicity of the Pfizer -BioNTech vaccine on a two-dose schedule (approximately 21 days apart) in three age groups: ages 5 to under 12 years; ages 2 to under 5 years; and ages 6 months to under 2 years. Based on the Phase 1 dose- escalation portion of the trial, children ages 5 to under 12 years received a two-dose schedule of 10 µg each while children under age 5 received a lower 3 µg dose for each injection in the Phase 2/3 study. The trial enrolled children with or without prior evidence of SARS-CoV-2 infection.
The Pfizer-BioNTech COVID-19 Vaccine, which is based on BioNTech’s proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.
U.S. Indication & Authorized Use
HOW IS THE VACCINE GIVEN?
The vaccine will be given as an injection into the muscle. Primary Series:
