The Phase 2/3 study is designed to evaluate the safety, reactogenicity and immunogenicity of three groups ages ≤18 - >12, ≤12 ->6, ≤ 6 - >2 years of healthy volunteers who receive two doses of the whole virion inactivated SARS-CoV-2 virus vaccine (COVAXIN®) 28 days apart.

Data will be un-blinded to the third-party bio-statistician and an interim analysis will be performed on day 56 for Immunogenicity, Safety, and submitted to CDSCO.

Interim Results

On November 5, 2021, Ocugen submitted a request to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of Ocugen’s COVID-19 vaccine candidate BBV152, known as COVAXIN™ outside of the U.S., for pediatric use.

The submission is based on results of a Phase 2/3 pediatric clinical trial conducted by Bharat Biotech in India with 526 children 2-18 years of age, which bridged immunogenicity data to a large, Phase 3 safety and efficacy clinical trial in nearly 25,800 adults in India.

The neutralizing antibody responses against wild-type strain in the pediatric age group of 2-18 years were equivalent to those seen in adults, ages 18+ years, in Bharat Biotech’s large Phase 3 efficacy and safety trial. More than 90 percent of the seroconversion rates were observed for antibody titers against S1, RBD, N proteins and wild-type neutralizing antibodies. These results suggest similar protection in children, ages 2-18, to that demonstrated in adults older than 18 years.
