Respiratory Tract Infections Clinical Trial
Official title:
Safety, Tolerability and Immunogenicity of a Plant-made H7 Virus-like Particle (VLP) Influenza Vaccine in Adults.
A phase I trial conducted in a single centre, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of 2 intramuscular injections of plant-based H7 VLP Influenza Vaccine administered to healthy adults, 18-60 years of age.
This study will consist of a dose-ranging in one hundred (100) subjects who will be randomized in parallel to a 1:1:1:1:1 ratio in five (5) groups of 20 subjects to receive one intramuscular injection at Days 0 and 21 of either a low, medium or high dose of H7 VLP vaccine mixed with Alhydrogel® 0.4% (0.5 mg Aluminum per dose) or a high dose of H7 VLP alone or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80). Twenty-one (21) days after each immunization, key safety and immunogenicity data will be collected and analysed. All subjects will be followed for safety until Day 228. ;
