Detailed Description
This is a phase 3 Event-Driven, randomized, double-blind, placebo-controlled, multicentre study to Evaluate the Efficacy, Safety, and Immunogenicity of BBV152, a Whole-Virion Inactivated SARS-CoV-2 Vaccine in Volunteers aged 18 years and above.
A total of 25,800 subjects will be enrolled and randomized in a 1:1 ratio to receive the BBV152 vaccine and control. All participants will be assessed for efficacy and safety endpoints and provide a Nasopharyngeal(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 the 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. A safety follow-up will be done for all.
In addition, sites will be segregated based on the study objectives:
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 an 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 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 placebo) 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.
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.

- Agrees not to participate in another clinical trial at any time during the study period.
- Agrees not to take any COVID-19 licensed vaccination for the entire duration of the study.
- Agrees to remain in the study area for the entire duration of the study.

- Temperature >38.0°C (100.4°F) or symptoms of an acute self-limited illness such as an upper respiratory infection or gastroenteritis within three days prior to each dose of vaccine.
- Resident of COVID-19 infection in the same household.
- Known case of HIV, hepatitis B, or hepatitis C infection.
- Receipt of any licensed/experimental vaccine within four weeks before enrolment in this study.
- Receipt of immunoglobulin or other blood products within the three months before vaccination in this study.
- Immunosuppression as a result of an underlying illness or treatment with immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation therapy within the preceding 36 months.
- Immunoglobulins, anti-cytokine antibodies, and blood products within 6 months prior to study vaccination, during, and 21 days following the last dose of vaccination.
- Pregnancy, lactation, or willingness/intention to become pregnant during the first 6 months after enrolment.
- Severe and/or uncontrolled cardiovascular disease, respiratory disease, gastrointestinal disease, liver disease, renal disease, an endocrine disorder, and neurological illness (mild/moderate well-controlled comorbidities are allowed)
