NCT ID:
NCT05258669
Brief Summary:
A randomized, observer-blind, placebo-controlled immuno-bridging, and broadening study to demonstrate the equivalence of the immune response between participants enrolled in Phase 3 efficacy trial in India and demographically diverse healthy adult participants in the US which matched in age and vaccine formulation setting to whom those efficacy results are extrapolated; and to assess the broadening of the BBV152 in participants who previously received two shots of messenger ribonucleic acid (mRNA) COVID-19 vaccine at least 6 months earlier or one-shots of viral vector J\&J/Janssen COVID-19 vaccine at least 2 months earlier. Safety and tolerability evaluation is a secondary endpoint.
Detailed Description:
Participants in stable health will be randomly assigned into one of four groups based on their age to receive either 6 µg of BBV152 or placebo in a 1:1 ratio. Each participant will receive 2 doses of the study vaccine by 0.5 mL intramuscular injection, the first on Day 0 and the second on Day 28. Data will be collected in an observer-blind manner.
Safety will be monitored by the Data and Safety Monitoring Board. The Data and Safety Monitoring Board will convene to perform safety reviews at 2 and 6 months and for immediate concerns regarding safety observations as needed.
Safety assessment will include monitoring solicited, unsolicited, serious, medically attended adverse events and potentially immune medicated medical conditions.
Since this is a bridging study, the maximum sample size of the data from the previous study will be 31 samples from the \<65 years population and 358 with samples from the 18 to \<65 years population.
