A Phase I Trial to Evaluate the Safety and Immunogenicity of an Influenza Vaccination Strategy Including a H3N2 M2SR Prime Followed by a Seasonal Quadrivalent Inactivated Vaccine Boost in a Pediatric Population 9-17 Years Old
In Brief
A Phase 1 clinical trial evaluating Influenza Virus Monovalent A/H3N2/Bris 10 M2SR Live Vaccine, Placebo, and 1 other intervention for Influenza and Influenza Immunisation. Completed, enrolled 43 participants across 1 site.
Detailed Summary
This is a Phase I double-blind, randomized, placebo-controlled study in 50 healthy adolescents and children, 9-17 years of age, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety and immunogenicity of a prime-boost regimen of H3N2 M2SR intranasal influenza vaccine (manufactured by FluGen) followed by licensed inactivated Quadrivalent Influenza Vaccine (QIV) boost administered intramuscularly Subjects will be enrolled in one of two groups in a 1:1 ratio. Arm 1 will receive one dose of M2SR intranasally on Day 1 and one dose of QIV on Day 92. Arm 2 will receive one dose of placebo (saline) intranasally on Day 1, and one dose of QIV on Day 92. Study duration will be approximately 28 months with patient participation duration approximately 13 months. The primary study objective is to assess the safety and reactogenicity of a monovalent live attenuated influenza H3N2 M2SR vaccine.

Timeline
Interventions
Live monovalent influenza A/H3N2-based M2SR (M2 defective Single Replication vaccine), comprised of 5 out of 8 gene segments on the donor virus influenza A/Puerto Rica/8/34. HA and NA derive from an A/Brisbane/10/2007-like virus. Administered intranasally as s single dose.
H3N2 M2SR vaccine placebo (normal saline). Administered intranasally as a single dose.
A quadrivalent cell culture inactivated vaccine (ccIV4) is an inactivated subunit influenza vaccine prepared from virus propagated in Madin Darby Canine Kidney (MDCK) cells indicated for the prevention of influenza disease caused by influenza virus subtypes A and type B contained in the vaccine. Administered intramuscularly as a single dose.
