A PHASE 1/2 STUDY TO EVALUATE THE SAFETY, TOLERABILITY, AND IMMUNOGENICITY OF COMBINED MODIFIED RNA VACCINE CANDIDATES AGAINST COVID-19 AND INFLUENZA IN HEALTHY INDIVIDUALS

BioNTech SE·interventional·Posted Oct 27, 2022·Updated Jul 23, 2025

In Brief

A Phase 2 clinical trial evaluating bivalent BNT162b2 (original/Omi BA.4/BA.5), qIRV (22/23), and 3 other interventions for Influenza, Human and COVID-19. Completed, enrolled 1,019 participants across 59 sites.

Detailed Summary

Substudy A: This is a Phase 1 randomized, open-label study to describe the safety and immunogenicity of up to 3 dose- level combinations of modRNA quadrivalent influenza vaccine (qIRV (22/23)) and bivalent BNT162b2 (original/Omi BA.4/BA.5). Participants will receive either: * qIRV (22/23)/bivalent BNT162b2 (original/Omi BA.4/BA.5), at 1 of the 3 dose-level combinations * qIRV (22/23) at dose level 1, * qIRV (22/23) at dose level 2, or * bivalent BNT162b2 (original/Omi BA.4/BA.5) at dose level 1 administered concurrently in the opposite arm to commercially licensed quadrivalent influenza vaccine (QIV). Substudy B: This Phase 1/2 study will describe the safety, tolerability, and immunogenicity of quadrivalent influenza vaccine (qIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), trivalent influenza vaccine (tIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), and bivalent influenza vaccine (bIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5) when given concurrently with licensed quadrivalent influenza vaccine (QIV).
