LigoCyte Pharmaceuticals Initiates a Randomized, Double Blind, Placebo Controlled Norovirus Vaccine Study
LigoCyte Pharmaceuticals, Inc. announced that it has initiated its third human clinical trial of its norovirus vaccine. The Phase I/II study will assess safety and immunogenicity associated with LigoCyte's investigational, nasally-delivered, dry powder vaccine in healthy adults. The study will also assess potential protection against clinical symptoms of norovirus infection by including a live virus challenge of subjects that have received either the vaccine or placebo. Clinical studies to date have shown the vaccine to be immunogenic and generally well tolerated in human subjects.
LigoCyte's norovirus vaccine is a needle-free, dry powder formulation based on virus like particle (VLP) antigens, which are highly purified protein products. By preserving the authentic conformation of the viral capsid, VLPs mimic the antigen presentation of the live virus while lacking the ability to reproduce or cause illness.
