Norovirus vaccine clinical trials

Randomized, multi-site, dose-escalation study of the safety and immunogenicity of four dosage levels of Intramuscular (IM) Norovirus Bivalent VLP Vaccine adjuvanted with MPL and Al (OH)3 compared to controls. Participants will receive two doses, by IM injection, 28 days apart. The hypotheses for this study are A Clinical Trial to Evaluate the Safety and Immunogenicity of Norovirus Bivalent Vaccine The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details In 2016 the World Health Organization stated that the development of a NoV vaccine should be considered an absolute priority. Unfortunately, the development of an effective NoV vaccine has proven extremely difficult, and only in recent years, some preparations have been tested in humans in advanced clinical trials NoV vaccine is being tested for protection against acute gastroenteritis (AGE) due to norovirus. The study will enroll maximum of 575 participants. Participants who previously received NoV vaccine in studies NOR-107, NOR-210 and NOR-204 will be enrolled

Brief Summary: The purpose of the research is to evaluate the safety and tolerability of the tetravalent recombinant Norovirus vaccine at different doses, to initially explore the immunogenicity of the vaccine, and to determine the appropriate dose of the product for later clinical trials.This trial adopts the seamless design of phase I/IIa, which is carried out in two phases, phase I and.
