Study to Assess Safety of an Inactivated H5N1 Influenza Vaccine Administered in GelVac Nasal Powder to Healthy Young Adults

• Status: Completed
• Trial end date: 2011-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a double-blind, placebo controlled, safety and immunogenicity study of GelVac™ nasal powder H5N1 influenza vaccine. Healthy male and female subjects between 18 and 49 years of age who are eligible for study participation will be enrolled in the trial. It is expected that 10 subjects will be screened to obtain 7 subjects who will be eligible for study participation.

The primary objective is to determine the frequency and severity of local and systemic adverse events of vaccine.

The secondary objective is to assess the immunogenicity of the vaccine based on geometric mean titers (GMT) of serum HAI, serum neutralizing, and nasal wash IgA antibodies.

14. use of experimental vaccines within 6 months prior to study entry, or expected use of experimental vaccines during the entire study period after inoculation with study vaccine.

15. participation in another clinical trial 30 days prior to study entry.

16. use of experimental devices or participation in a medical procedure trial within the month prior to study entry, or expected use of experimental devices or participation in a medical procedure trial during the entire study period.
