5. Study Description

Brief Summary
This is a Phase I double-blind, randomized, placebo-controlled study in 250 healthy adults, 18-49 years of age, inclusive, who are in good health and meet all eligibility criteria. The purpose of this dose escalation clinical study is to assess the safety, tolerability/reactogenicity, and immunogenicity of H3N2 M2SR investigational vaccines for prevention of influenza, when delivered at higher dosages or in two doses . Eligible subjects will be screened and randomized to receive two administrations 28 days apart of Sing2016 M2SR at three dose levels (low, medium, high), Bris10 M2SR at one dose level (low), or placebo in a 1:1:1:1:1 ratio. Study duration will be approximately 8 months with subject participation duration approximately 7 months. The primary study objective is to assess the safety and reactogenicity of a monovalent live single replication influenza H3N2 M2SR vaccine.
Detailed Description
This is a Phase I double-blind, randomized, placebo-controlled study in 250 healthy adults, 18-49 years of age, inclusive, who are in good health and meet all eligibility criteria. This dose escalation clinical study is designed to assess the safety, tolerability/reactogenicity, and immunogenicity of H3N2 M2SR investigational vaccines for prevention of influenza, when delivered at increasing dosages or in two doses. Subjects will be enrolled in five groups in a 1:1:1:1:1 ratio. Arm 1 will receive a low dose of Sing2016 M2SR intranasally on days 1 and 29. Arm 2 will receive a medium dose of Sing2016 M2SR intranasally on days 1 and 29. Arm 3 will receive a high dose of Sing2016 M2SR intranasally on days 1 and 29. Arm 4 will receive a low dose of Bris16 M2SR intranasally on days 1 and 29. Arm 5 will receive a placebo intranasally on days 1 and 29. Study duration will be approximately 8 months with subject participation duration approximately 7 months. The primary study objective is to assess the safety and reactogenicity of a monovalent live single replication influenza H3N2 M2SR vaccine. The secondary study objectives are to evaluate systemic and mucosal immune responses induced by H3N2 M2SR vaccination.
