• Data from 25,800 participants in Phase 3 trial in India, received vaccine or placebo in a 1:1 ratio showed that the vaccine candidate was well tolerated and demonstrated 81% efficacy in preventing COVID-19 in those without prior infection after the second dose.
  • Clinical trial to continue through to final analysis at 130 confirmed cases in order to gather further data and to evaluate the efficacy of COVAXIN in additional secondary study endpoints.

MALVERN, PA, USA I March 03, 2021 I Ocugen, Inc. (NASDAQ: OCGN), a biopharmaceutical company focused on discovering, developing, and commercializing gene therapies to cure blindness diseases and developing a vaccine to save lives from COVID-19, today announced that its co-development partner, Bharat Biotech, announced the results of the first interim analysis of its Phase 3 study of COVAXIN, a whole virion inactivated COVID-19 vaccine candidate. COVAXIN demonstrated a vaccine efficacy of 81%.

“We are thrilled with the interim efficacy results of Bharat Biotech’s Phase 3 trial of COVAXIN in India. These results, which in part suggest significant immunogenicity against the rapidly emerging UK variant, represent an additional step towards outlining the regulatory pathway for EUA and approval in the United States. COVAXIN, a whole virion based vaccine candidate, is designed to fill a significant unmet need in our national arsenal of vaccines against COVID-19,” said Dr. Shankar Musunuri, Chairman of the Board, Chief Executive Officer, and Co-founder of Ocugen.

“Today’s results from the interim analysis of Bharat Biotech’s Phase 3 trial of COVAXIN mark a milestone in the development of another critical vaccine option for the US market. COVAXIN has been shown to induce immune responses against multiple protein antigens of the virus potentially reducing the possibility of mutant virus escape. This breadth of immune responses has been demonstrated by ability of antibodies induced by COVAXIN to neutralize the UK variant of SARS-Cov-2,” said Dr. Bruce Forrest, member of the vaccine scientific advisory board of Ocugen.

Interim Phase 3 Results as Reported by Bharat Biotech

Bharat Biotech’s Phase 3 clinical trial enrolled 25,800 participants between 18-91 years of age, including 2,433 over the age of 60 and 4,500 with comorbidities. The primary endpoint of the Phase 3 clinical trial is based on the first occurrence of PCR-confirmed symptomatic (mild, moderate or severe) COVID-19 with onset at least 14 days after the second study vaccination in serologically negative (to SARS-CoV-2) adult participants at baseline.

The first interim analysis is based on 43 cases, of which 36 cases of COVID-19 were observed in the placebo group versus 7 cases observed in the COVAXIN group, resulting in a point estimate of vaccine efficacy of 80.6%.

The interim analysis included a preliminary review of the safety database, which showed that severe, serious, and medically attended adverse events occurred at low levels and were balanced between vaccine and placebo groups. The trial’s conduct and monitoring are as per Good Clinical Practice guidelines and have been outsourced to IQVIA.

Analysis from the National Institute of Virology indicates that vaccine-induced antibodies can neutralize the UK variant strains and other heterologous strains, which has been published in bioRxiv.

Bharat Biotech expects to share further details of the trial results as additional data become available. An additional interim analysis is planned for 87 cases, and the final analysis is planned for 130 cases. All data from the second interim and final analyses will be shared via pre-publication servers as well as submitted to a peer-reviewed journal for publication.

About COVAXIN

COVAXIN, India’s COVID-19 vaccine by Bharat Biotech, is developed in collaboration with the Indian Council of Medical Research (ICMR) – National Institute of Virology (NIV). COVAXIN is a highly purified and inactivated vaccine that is manufactured using a vero cell manufacturing platform with an excellent safety track record of more than 300 million doses supplied.

In addition to generating strong immune response against multiple antigens, COVAXIN is shown to generate memory T cell responses, for its multiple epitopes, indicating longevity and a rapid antibody response to future infections. With published data demonstrating a safety profile superior to several other vaccines, COVAXIN is packaged in multi-dose vials that can be stored at 2-8oC.
