Bharat Biotech has announced commencement of Phase III trials of COVAXIN on Monday, the company said. The Phase-III trials will involve 26,000 volunteers across India, conducted in partnership with ICMR.

It is the largest clinical trial conducted for a COVID-19 vaccine in India.

This is India’s first Phase 3 efficacy study for a COVID-19 vaccine, and the largest phase III efficacy trial ever conducted in India. The trial has been approved by the Drugs Controller General of India, said Bharat Biotech.

“Trial volunteers will receive two intramuscular injections approximately 28 days apart,” said the company.

Participants will be randomly assigned to receive COVAXIN or placebo. The trial is double blinded, such that the investigators, the participants and the company will not be aware of who is assigned to which group.

COVAXIN has been evaluated in  1000 subjects in Phase I and Phase II clinical trials, with promising safety and immunogencity data. Volunteers who wish to participate in this trial should be adults over 18 years of age.

COVAXIN, India's indigenous COVID-19 vaccine by Bharat Biotech is developed in collaboration with the Indian Council of Medical Research (ICMR) - National Institute of Virology (NIV).

This indigenous, inactivated vaccine is developed and manufactured in Bharat Biotech's BSL-3 (Bio-Safety Level 3) bio containment facility. COVAXIN is a highly purified and inactivated vaccine, manufactured in a vero cell manufacturing platform with an excellent safety track record of more than 300 million doses supplied.

Speaking on the occasion, Suchitra Ella Joint Managing Director of Bharat Biotech added, “The development and clinical evaluation of COVAXIN™ marks a significant milestone for vaccinology in India, for a novel vaccine. It is important for Indian companies to innovate and develop indigenous vaccines, especially during a pandemic. COVAXIN™ has garnered interest from several countries worldwide for supplies and introduction.”

This multicenter phase III study is conducted at the following sites across India. Participating volunteers who undergo vaccination in the Phase III trials, will be monitored to detect occurrence of COVID-19 disease. The trials will be conducted at 22 centres across the country.
