4 Clinical Trials for Various Conditions
The purpose of the Phase 1 Part of this study is to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1403 and mRNA-1405 in healthy adult participants 18 to 49 years of age and 60 to 80 years of age. The purpose of the Phase 2 Part of the study is to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1403 in healthy adult participants 18 to 80 years of age.
The primary objectives of this study are to evaluate the safety and reactogenicity of mRNA-1403, and to demonstrate the efficacy of mRNA-1403 to prevent protocol-defined moderate or severe norovirus acute gastroenteritis (AGE) associated with vaccine matched genotypes.
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.
The ARIES Norovirus Assay is a real-time PCR based qualitative in vitro diagnostic test for the direct detection of Norovirus GI/GII RNA from stool specimens obtained from symptomatic patients. The purpose of this study is to establish the diagnostic accuracy of ARIES Norovirus Assay.
