Safety and Immunogenicity Study of Two Doses of an Inactivated H5N1 Influenza Vaccine (Whole Virion, Vero Cell Derived)

October 7, 2015 updated by: Ology Bioservices

An Open-Label Phase I/II Study to Assess the Safety and Immunogenicity of Two Doses of a Vero Cell Derived, Whole Virus Clade 2 H5N1 Influenza Vaccine in Healthy Volunteers Aged 21 to 45 Years

The objectives of this Phase I/II study are to assess the safety and immunogenicity of two different dose levels of a non-adjuvanted H5N1 influenza vaccine in a healthy young adult population. Subjects will be randomized 1:1 to receive two intramuscular injections (21 days apart) of the vaccine containing either 3.75 µg or 7.5 µg H5N1 hemagglutinin (HA) antigen in a non-adjuvanted formulation. Subjects will be monitored for safety and for antibody response to the vaccine. A data safety monitoring board will review the safety data after the first and second vaccination.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 45 years (Adult)

Accepts Healthy Volunteers
