Study Comparing Immune Response to, and Safety of, Fluviral and Fluzone Influenza Vaccines in Persons 50 y.o. and Over

This study has been completed.
Information provided by:
ID Biomedical Corporation, Quebec Identifier:
First received: October 3, 2005
Last updated: January 19, 2007
Last verified: October 2005
The goal of this study is to determine whether the immune responses induced by Fluviral, the investigational vaccine, are comparable to those induced by Fluzone, which is an influenza vaccine currently licensed in the U.S. The study focuses on persons 50 years old and over. In addition, the study will compare the rate of reactions to the two vaccines, and the general health of persons who receive them over the 42 days after immunization.

Condition Intervention Phase
Influenza Biological: Influenza virus vaccine (Fluviral) Biological: Influenza virus vaccine (Fluzone) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double-Blind
Primary Purpose: Educational/Counseling/Training
Official Title: A Non-Inferiority Comparison of Fluviral™ Influenza Vaccine to a U.S. Licensed Inactivated Split-Virion Vaccine (Fluzone®) in Adults ≥ 50 Years Old Living in the Community

Further study details as provided by ID Biomedical Corporation, Quebec:

Primary Outcome Measures:
  • Rate of signficant rises in serum antibody titers against viruses in the vaccines.
  • Geometric mean serum antibody titers on day 21.

Secondary Outcome Measures:
  • Rates of specific, solicited vaccine reactogenicicty complaints.
  • Rates of adverse events.

Estimated Enrollment: 900
Study Start Date: October 2005
Estimated Study Completion Date: February 2006
Detailed Description:
Yearly influenza epidemics are responsible for excess hospitalizations and deaths in the elderly population, and also cause lost work and productivity among the healthy, working elderly. Fluviral, a product now licensed in Canada, is being tested to determine whether it is as active in causing immune responses, and as safe as a currently licensed U.S. vaccine in persons 50 y.o. and over.
