Brief Summary
This is a phase 3 Event Driven, randomized, double-blind, placebo controlled ,multicentre study to evaluate the Efficacy, Safety, and Immunogenicity of BBV152B, a Whole-Virion Inactivated SARS-CoV-2 Vaccine in Volunteers aged 18 years and above.
Protocol Version 1.0 to Version 2.0
·BBV-152B formulation is chosen based on the
Phase 1 interim report which shows that the immunogenicity of BBV-152B is
higher compared to BBV-152A although the difference was not statistically
different.
·The primary efficacy endpoint is modified to
include the participants who meet the case definition for Severe symptomatic COVID-19 .
·A safety endpoint to include the Adverse Events
of Special Interest (AESIs) such as anaphylaxis, generalized convulsion, and
vaccine associated enhanced respiratory disease (VAERD) is included.
Protocol Version 2.0 to version 3.0
·The case definition of symptomatic COVID-19
Endpoint is modified based on the SEC
recommendation.
·Risks from study participation (Category 1 and Category 2 &3) is Updated
for easy understanding for the participant
A total of 25,800 subjects will be enrolled and randomized in a 1:1 ratio to receive BBV152B vaccine and control. All participants will be assessed for efficacy and safety endpoints and provide a NP swab and blood sample before the first dose of IP. The NP swab and blood collected will be subject to RT-PCR and Anti-SARS-CoV-2 IgG antibodies. The results of this will not affect enrollment of the participant. Participants who are found to be positive for either RT-PCR Or Anti-SARS-CoV-2 IgG antibodies will be excluded from the primary efficacy analysis. Safety follow up will be done for all.
In addition, sites will be segregated based on the study objectivies:
Category 1 (Symptomatic): In addition to administering the IP, a series of post-dose telephonic follow-up visits will be scheduled to detect suspect symptomatic COVID-19 infections. If a suspect is identified, a nasopharyngeal sample will be collected from the participant for detecting the presence of COVID-19 infection. Telephonic follow-up will occur at 15 Day intervals.
Category 2 (Symptomatic/Asymptomatic): In addition to administering the IP, a series of post-dose Nasopharyngeal samples for detecting incidence of asymptomatic COVID-19 infection at 1-Month intervals will be collected
Category 3 (Symptomatic/Asymptomatic+Immunogenicity): In addition to administering the IP and collecting NP samples, a series of blood samples will be collected for analyzing serum for immunological assessments.
The purpose of this Phase 3 study is to evaluate the protective efficacy, safety, and immunogenicity of the whole-virion inactivated SARS-CoV-2 vaccine, BBV152B. The Phase 3 study will follow randomized study participants for efficacy until virologically confirmed (RT-PCR positive) symptomatic COVID-19 participants will be eligible for the primary efficacy analysis. After reaching the target number (n=130) of symptomatic COVID-19 cases, the study will continue to assess safety until the completion of the study duration.It is planned to continue the Phase 3 trial until 130 study participants in the per-protocol population develop PCR-confirmed symptomatic COVID-19 disease during follow-up beginning 14 days after the second dose of vaccine or placebo. We estimate that approximately 25,800 participants should be randomized to accrue these 130 events. The Lot-to-Lot consistency (Immunogenicity) study will be nested within the Phase 3 (Efficacy) study (in three selected sites). The Immunogenicity study will assess the immune response of a 2-dose regimen of BBV152B vaccine through geometric mean titers (GMTs) by neutralizing antibody, S-protein, and RBD specific anti-IgG binding titer in a subset of 600 (450 vaccine: 150 control) participants, across three consecutive manufacturing Lots. Data generated through Day 56 (Month 2) will be unblinded only to the biostatistician for evaluation of immune responses in the Immunogenicity subset. A Formal interim analyses are planned when approximately 1/3 and 2/3 of the target number of participants with confirmed symptomatic COVID-19 have been accrued, to determine whether the sample size and/or length of follow-up should be increased .This interim report containing safety and immunogenicity data will be submitted to CDSCO.
