UMIN-CTR Clinical Trial

Basic information
Official scientific title of the study	The analysis of mucosal immune responses induced by intranasal administration of an inactivated influenza virus vaccine in human.
Title of the study (Brief title)	The analysis of antibody, B and T cell responses induced by intranasal administration of an inactivated whole-virus vaccine (A/H5N1) in human, and the characterization of secretory IgA antibodies in nasal mucus.

Objectives
Narrative objectives1	The goal of this study is to determine adaptive immune responses in healthy adult volunteers receiving an intranasal administration of an inactivated whole-virus vaccine (A/H5N1, 45ug HA/dose) with or without carboxy vinyl polymer (CVP), that increase the viscosity of vaccine. Antibody responses in serum and nasal mucus, B and T cell responses will be evaluated. In addition, characterization of secretory IgA antibodies in nasal mucus and evaluation of the neutralization efficacy of those antibodies will be performed in this study.

Assessment
Primary outcomes	Neutralization, HI, and HA-specific antibody titers before and after intranasal vaccination. The proportion of memory B cell or plasma cell in peripheral blood mononuclear cells, and the cytokine profile. The analysis of the antibody repertoire induced by the intranasal vaccination. The characterization of secretory IgA antibodies in nasal mucus. Survey on side reaction after vaccination.

Intervention
No. of arms	2
Purpose of intervention	Prevention
Type of intervention	Vaccine
Interventions/Control_1	Intranasal administration of an inactivated whole-virus vaccine (A/H5N1, 45ug HA/dose) is performed twice with a 3 week interval. About a half year later, the same vaccination will be performed once more. For the characterization of S-IgA antibodies, a few participants will receive two additional vaccinations after the last vaccination.
Interventions/Control_2	Intranasal administration of an inactivated whole-virus vaccine (A/H5N1, 45ug HA/dose) with CVP is performed twice with a 3 week interval. About a half year later, the same vaccination will be performed once more. For the characterization of S-IgA antibodies, a few participants will receive two additional vaccinations after the last vaccination.
