Ocugen (OCGN) surges on additional COVID-19 vaccine data

Shares of Ocugen (OCGN) skyrocketed 12% today on when it announced additional COVID-19 vaccine data demonstrating 100% protection against severe disease including hospitalization.

Primary efficacy in the second interim analysis demonstrates COVAXIN to be 78% effective after the second dose in preventing COVID-19 in those without prior infection and 70% efficacy against asymptomatic COVID-19 infections; indicates potential to significantly reduce virus transmission.

Drug developer partner Bharat Biotech, shared positive results of the second interim analysis of its Phase 3 study of COVAXIN, a whole virion inactivated COVID-19 vaccine candidate. COVAXIN demonstrated a vaccine efficacy in mild, moderate, and severe COVID-19 disease of 78% with efficacy against severe COVID-19 disease alone of 100%.

The press release states:

“Bharat Biotech’s Phase 3 clinical trial enrolled 25,800 participants between 18-91 years of age in India, 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 second interim analysis is based on accruing more than 87 symptomatic cases of COVID-19. However, due to the recent surge in cases in India, 127 symptomatic cases were recorded, resulting in a point estimate of vaccine efficacy of 78% (95%CI: 61-88) against mild, moderate, and severe COVID-19 disease. The trial will be continuing to its pre-planned conclusion.

The efficacy against asymptomatic COVID-19 infection was 70%, based on a subgroup of approximately 8,000 participants who visited the clinical trial site each month for an RT-PCR test.”
