H3N2 M2SR in Pediatric Population

Influenza Clinical Trial

Official title:
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

Clinical Trial 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.

The primary study objective is to assess the safety and reactogenicity of a monovalent live attenuated influenza H3N2 M2SR vaccine. The secondary study objectives are to identify circulating and mucosal antibody responses induced by H3N2 M2SR vaccination and to identify cellular immune responses induced by H3N2 M2SR vaccination. ;
