Covaxin showed 81% interim efficacy: Bharat Biotech on Phase 3 results

Bharat Biotech’s homegrown Covid-19 vaccineç Covaxin, has shown an interim vaccine efficacy of 81% in late-stage clinical trials, the Hyderabad-based company said on Wednesday. That’s better than Bharat Biotech’s guidance last year of around 60% and India’s benchmark of 50% for vaccines targeting the novel

The trials involved 25,800 participants and was conducted in partnership with Indian Council of Medical Research (ICMR), the Indian government’s medical research body. This was the largest ever trial conducted in India.

“Today is an important milestone in vaccine discovery, for science and our fight against With today’s results from our Phase 3 clinical trials, we have now reported data on our Covid-19 vaccine from Phase 1, 2, and 3 trials involving around 27,000 participants,” Chairman and Managing Director Krishna Ella said.

Covaxin demonstrates high clinical efficacy trend against Covid-19 but also significant immunogenicity against the rapidly emerging variants, he added.

Participants received a vaccine or placebo in a 1:1 ratio, which showed that the vaccine candidate was well tolerated, said the company.

“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,” the company said.

The interim analysis was based on 43 recorded cases of Covid-19 in the trial of 25,800 participants.

Thirty-six of the 43 cases were recorded in participants who received a placebo, compared with seven cases in people who were given the vaccine, pointing to an efficacy rate of 80.6%, the company said.

India had approved Covaxin in January without late-stage efficacy data, raising questions about its effectiveness.

Earlier this week, Indian Prime Minister Narendra Modi was inoculated with the first dose of Covaxin.

The findings cement Bharat Biotech’s claims of the vaccine being safe and may help overcome vaccine hesitancy as India rolls out one of the world’s biggest inoculation programs to contain Covid-19 outbreak. The data is also a rebuttal for critics who had questioned the unprecedented haste with which the indigenously produced shot was approved in early January and deployed among India’s frontline health care workers even before providing any Phase 3 trial data.

In June last year, India’s drug regulator permitted the family-run and closely-held to develop a homegrown vaccine in record time. Soon after, work on Covaxin was bogged down by controversies ranging from unrealistic government schedules to sporadic reports of adverse reactions.

Despite the vaccine receiving the emergency use approval in January, many of those in the priority list for receiving the initial injections failed to turn up for their shots, concerned that they may be given the experimental vaccine. The sign ups among those willing to be vaccinated have improved in the past week.

Officials in New Delhi and the management of Bharat Biotech have vigorously defended the vaccine’s safety and effectiveness during the roll out. The new data may boost uptake in a nation that has registered the world’s second-largest outbreak and is reporting a further spurt of infections in some states such as Maharashtra, triggering fears of regional restrictions after a lockdown in March last year that hobbled the economy.

India has also approved the shot from Astrazeneca Plc’s local partner, the Ltd., but the country’s inoculation campaign saw a tepid response in the initial weeks, endangering its target of reaching about a quarter of its population by August.

With a capacity to manufacture about 300 million doses on an annual basis, the promising efficacy data will likely aid Bharat Biotech find further export markets. The company shipped the vaccine to Brazil this month and has signed an agreement with Ocugen Inc. to co-develop the vaccine for the U.S.

The encouraging news comes at a time when India has seen a sudden spurt in new cases and has also entered the next phase of Covid-19 vaccination, whih commenced from March 1 for those who are over 60 years of age and for people aged 45 and above with specified co-morbid conditions.

More than 1.56 crore (1,56,20,749) vaccine doses have been administered through 3,12,188 sessions, according to provisional report till Wednesday 7 am.

These include 67,42,187 healthcare workers (1st dose), 27,13,144 HCWs (2nd dose), 55,70,230 frontline workers (1st dose) and 834 FLWs (2nd dose), 71,896 beneficiaries aged more than 45 years with specific co-morbidities (1st dose) and 5,22,458 beneficiaries aged more than 60 years.

Maharashtra, Kerala, Punjab, Tamil Nadu, Gujarat and Karnataka continue to report a surge in fresh COVID-19 cases and they account for 85.95 per cent of the cases reported in a span of 24 hours, the Union Health Ministry said on Wednesday.

The ministry said that 14,989 new cases were registered in a span of 24 hours. Maharashtra has reported the highest daily new cases at 7,863. It is followed by Kerala with 2,938, while Punjab reported 729 new cases.

“Maharashtra, Punjab, Gujarat, Madhya Pradesh, Delhi, Haryana and Karnataka have shown the maximum increase in new cases on a week on week basis,” the ministry said.

Maharashtra alone accounted for a weekly increase of 16,012 cases.

In percentage terms, Punjab reported a weekly increase of 71.5 per cent (1,783 cases).

The Centre is continuously engaging with the states and union territories reporting higher caseload of active cases and those reporting a spike in the daily new Covid-19 cases, the ministry underlined. States and UTs have been advised to maintain a continued rigorous vigil for containing the spread of COVID-19 so that the gains of collective efforts are not squandered away, the ministry said.
