March 4, 2019 updated by: Altimmune, Inc.
Extension Study for Study ALT-103-201: One-year Follow-up for the 1×10(11th) vp NasoVAX Group
This study is an extension to Study ALT-103-201, a Phase 2a, randomized, double-blind, placebo-controlled trial to evaluate the safety and immunogenicity of NasoVAX in healthy adults 18 to 49 years of age.

Detailed Description
This study is an extension to Study ALT-103-201 to evaluate immunogenicity of NasoVAX administered by intranasal spray at a single dose of 1×1011 vp at Day 366 (± 60 days).
Up to 15 subjects who received NasoVAX at the 1×10(11th) vp dose in Study ALT-103-201 will be screened, and a serum sample will be collected from each eligible subject for evaluation of influenza HAI assay against influenza A/California/07/2009(H1N1), a strain homologous to the one used for NasoVAX (monovalent AdcoCA09.HA).
Ad5 antibody neutralization assay may also be performed.

Extension of NasoVAX high dose
A serum sample will be collected from each eligible subject who received NasoVAX at the 1×10(11th) vp dose in Study ALT-103-201 for evaluation of influenza hemagglutination assay against influenza A/California/07/2009(H1N1), a strain homologous to the one used for NasoVAX (monovalent AdcoCA09.HA).
Ad5 antibody neutralization assay may also be performed.
