Phase 1, Randomized Controlled Dose Escalation, Safety and Immunogenicity Study of Intramuscular Norovirus GI.1/GII.4 Bivalent Virus-Like Particle (VLP) Vaccine Adjuvanted With Monophosphoryl Lipid A (MPL) and Aluminum Hydroxide [Al(OH)3] in Adults
In Brief
A Phase 1 clinical trial evaluating NoV GI.1/GII.4 Bivalent VLP Vaccine and Saline for Gastroenteritis. Completed, enrolled 102 participants across 3 sites.
Detailed Summary
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: * The incidence of adverse events after vaccination with IM Norovirus Bivalent VLP Vaccine will be similar to the incidence of adverse events after other IM vaccines including CERVARIX® which contains MPL and Al(OH)3. * Two doses of IM Norovirus Bivalent VLP Vaccine will be more immunogenic than one dose. * The post-vaccination serum antibody responses, the number of antibody secreting cells (ASC), including homing markers, and memory B-cell responses directed against norovirus antigens will be increased after IM Norovirus Bivalent VLP Vaccine compared to controls.
