New Delhi, Jul 6: The Indian Academy of Sciences, a Bengaluru-based body of scientists, has said the Indian Council for Medical Research's (ICMR) target to launch a coronavirus vaccine by August 15 is "unfeasible" and "unrealistic".

The IASc said while there is an unquestioned urgent need, vaccine development for use in humans requires scientifically executed clinical trials in a phased manner.

While administrative approvals can be expedited, the "scientific processes of experimentation and data collection have a natural time span that cannot be hastened without compromising standards of scientific rigour", the IASc said in a statement.

In its statement, the IASc referred to the ICMR's letter which states that "it is envisaged to launch the vaccine for public health use latest by 15th August 2020 after completion of all clinical trials".

The ICMR and Bharat Biotech India Limited, a private pharmaceutical company, are jointly developing the vaccine against the novel coronavirus -- SARS-CoV-2.

The IASc welcomes the exciting development of a candidate vaccine and wishes that the vaccine is quickly made available for public use, the statement said.

"However, as a body of scientists including many who are engaged in vaccine development IASc strongly believes that the announced timeline is unfeasible. This timeline has raised unrealistic hope and expectations in the minds of our citizens," it said.

Aiming to launch an indigenous COVID-19 vaccine by August 15, the ICMR had written to select medical institutions and hospitals to fast-track clinical trial approvals for the vaccine candidate, COVAXIN.

Experts have also cautioned against rushing the process for developing a COVID-19 vaccine and stressed that it is not in accordance with the globally accepted norms to fast-track vaccine development for diseases of pandemic potential.

The IASc said trials for a vaccine involve evaluation of safety (Phase 1 trial), efficacy and side effects at different dose levels (Phase 2 trial), and confirmation of safety and efficacy in thousands of healthy people (Phase 3 trial) before its release for public use.

Clinical trials for a candidate vaccine require participation of healthy human volunteers. Therefore, many ethical and regulatory approvals need to be obtained prior to the initiation of the trials, it added.

The IASc said the immune responses usually take several weeks to develop and relevant data should not be collected earlier.

"Moreover, data collected in one phase must be adequately analysed before the next phase can be initiated. If the data of any phase are unacceptable then the clinical trial is required to be immediately aborted," it said.

For example, if the data collected from Phase 1 of the clinical trial show that the vaccine is not adequately safe, then Phase 2 cannot be initiated and the candidate vaccine must be discarded.

For these reasons, the Indian Academy of Sciences believes that the announced timeline is "unreasonable and without precedent", the statement said.

"The Academy strongly believes that any hasty solution that may compromise rigorous scientific processes and standards will likely have long-term adverse impacts of unforeseen magnitude on citizens of India," it said.

Bengaluru, Apr 30: Shares of Glenmark Pharmaceuticals Ltd rose almost 9% on Thursday after the Indian drugmaker got an approval to conduct clinical trials with antiviral drug favipiravir, seen as a potential treatment for COVID-19.

Favipiravir, manufactured under the brand name Avigan by a unit of Japan's Fujifilm Holdings Corp and approved for use as an anti-flu drug in the Asian island country in 2014, has been effective, with no obvious side-effects, in helping coronavirus patients recover, a Chinese official told reporters at a news conference last month.

"After having successfully developed the API and the formulations ... Glenmark is all geared to immediately begin clinical trials on favipiravir on COVID-19 patients in India," Sushrut Kulkarni, executive vice-president for Global R&D, Glenmark Pharmaceuticals, said in a statement. 

The Drug Controller General of India, the country's drug regulator, did not immediately respond to Reuters request for comment.

On Wednesday, another Indian pharmaceutical company, Strides Pharma Science Ltd, said it had developed and commercialized favipiravir antiviral tablets, and had applied to Indian drug authorities to start trials.

Shares of Mumbai-based Glenmark Pharmaceuticals, which rose as much as 8.9% to 359 rupees ($4.78), was trading up 5.9%, as of 0407 GMT.

Mumbai, Jul 13: In a significant landmark, the BrihanMumbai Municipal Corporation (BMC) has achieved a doubling-rate of 50 days for COVID-19 cases, a top official said on Monday.

This was possible because of the civic body's 'open testing policy', implying tests without prescriptions, making it the only city in the country to implement it.

"After the open testing policy, our testing has gone up from 4,000 to 6,800, daily. But the total positive cases have come down from 1,400 to 1,200 now," BMC Municipal Commissioner I.S. Chahal told IANS.

Of these 1,200 positive cases, the symptomatic cases are less than 200, so the BMC needs only 200 beds daily, the civic chief said.

Even the BMC's discharge rate now stands at 70 percent, and on Sunday, after allotting beds to all patients, there were still 7,000 COVID beds plus 250 ICU beds lying vacant, said Chahal.

For this achievement, Chahal gave the credit to the entire 'Team BMC' where - despite losing a little over 100 officials to the virus - civic officials and other Corona warriors are engaged 24x7 in controlling the pandemic for over four months.

Since the first case was detected in Mumbai on March 11 (after the state's first infectees in Pune on March 9) and the state's first death notched in Mumbai on March 17, the current Maharashtra Covid-19 tally stands at 2,54,427 cases and fatalities at 10,289, while Mumbai has recorded 92,988 cases with a death toll of 5,288.
