Pfizer and BioNTech Submit Application to U.S. FDA for Emergency Use Authorization of Omicron BA.4/BA.5-Adapted Bivalent Vaccine Booster in Children 5 Through 11 Years of Age

NEW YORK and MAINZ, GERMANY, September 26, 2022 — Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced they have completed a submission to the U.S. Food and Drug Administration (FDA) requesting Emergency Use Authorization (EUA) of a 10-µg booster dose of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine for children 5 through 11 years of age. The request for Emergency Use Authorization of the Omicron BA.4/BA.5-adapted bivalent vaccine in this age group is supported by safety and immunogenicity data from the companies’ Omicron BA.1-adapted bivalent vaccine, non-clinical and manufacturing data from the companies’ 10-µg Omicron BA.4/BA.5-adapted bivalent vaccine, and preclinical data from the companies’ Omicron BA.4/BA.5-adapted bivalent vaccine. An application to extend the Omicron BA.4/BA.5-adapted bivalent vaccine marketing authorization in the European Union to include children 5 through 11 years of age will be submitted to the European Medicines Agency (EMA) in the coming days.

The companies have also initiated a Phase 1/2/3 study (NCT05543616, C4591048) to evaluate the safety, tolerability and immunogenicity of different doses and dosing regimens of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in children 6 months through 11 years of age. This pediatric study is consistent with regulatory guidance and follows a previous Phase 1/2/3 trial involving these age groups that demonstrated the original Pfizer-BioNTech COVID-19 vaccine is well-tolerated and offers a high level of protection against COVID-19, measured at a time when the Omicron BA.2 strain was highly prevalent.

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 for BNT162b2 (COMIRNATY^®) 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.

About the Study
The Phase 1/2/3 pediatric clinical study will have four substudies examining different bivalent COVID-19 vaccine dose regimens and dose levels across different ages, including:

• Substudy A (ages 6 through 23 months who are COVID-19 vaccine-naïve): Phase 1 dose-finding study will evaluate 3-µg, 6-µg and 10-µg dose levels of the bivalent vaccine. Based on Phase 1, participants in the Phase 2/3 will receive the selected dose as a three-dose primary series, followed by a booster dose.
• Substudy B (ages 6 months through 4 years who previously received 2-3 doses of original COVID-19 vaccine): Those who have received two doses of the original COVID-19 vaccine prior to enrollment will receive both a third and fourth 3-µg dose of the bivalent vaccine. Those who have previously received three doses of the original vaccine will receive a 3-µg booster (fourth) dose of the bivalent vaccine.
• Substudy C (ages 6 months through 4 years who previously received 3 doses of original COVID-19 vaccine): Phase 1 dose-finding study will evaluate 6-µg and 10-µg dose levels of the bivalent vaccine as a fourth dose. Based on Phase 1, Phase 2/3 will receive the selected dose as a fourth dose.
• Substudy D (ages 5 through 11 years who previously received 2-3 doses of original COVID-19 vaccine): Participants will receive the bivalent vaccine as either a third or fourth 10-µg booster dose.
