NCT05596734

Brief 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).

Outcome Measures

Primary Outcomes (24)

  • SSA: Percentage of Participants With Local Reactions up to 7 Days Following Vaccination (18-64 Years)

    Local reactions included pain at the injection site, redness and swelling and were recorded by participants in an electronic diary. Redness and swelling were measured and recorded in measuring device units, where 1 measuring device unit=0.5 centimeter (cm). Redness and swelling were graded as mild (Grade 1): greater than (\>) 2.0 cm to 5.0 cm; moderate (Grade 2): \>5.0 cm to 10.0 cm; severe (Grade 3): \>10 cm; potentially life-threatening (Grade 4): necrosis or exfoliative dermatitis (redness) and necrosis (swelling). Pain at injection site was graded as mild (Grade 1): did not interfere with activity; moderate (Grade 2): interfered with activity; severe (Grade 3): prevented daily activity and potentially life-threatening (Grade 4): emergency room visit or hospitalization for severe pain.
