Roche Gets Emergency Use Authorisation in India for Investigational Antibody Cocktail Casirivimab, Imdevimab used in Covid-19 Treatment

Roche India

Roche India has announced that the Central Drugs Standards Control Organisation (CDSCO) has provided an Emergency Use Authorisation (EUA) for Roche’s antibody cocktail (Casirivimab and Imdevimab) in India. This approval was based on the data that have been filed for the EUA in the US, and the scientific opinion of the Committee for Medicinal Products for Human Use (CHMP) in the European Union. This EUA will now enable Roche to import the globally manufactured product batches to India and will be marketed as well as distributed in the country through a strategic partnership with Cipla Ltd.

The antibody cocktail (Casirivimab and Imdevimab) is to be administered for the treatment of mild to moderate coronavirus disease 2019 (COVID-19) in adults and pediatric patients (12 years of age or older, weighing at least 40 kg) who are confirmed to be infected with SARS-COV2 and who are at high risk of developing severe COVID-19 disease. It could significantly help these high-risk patients before their condition worsens. On March 23 2021, Roche announced that a large phase-III global trial (n=4,567) in high-risk non-hospitalised COVID-19 patients (“outpatients”) met its primary endpoint, showing that Casirivimab and imdevimab significantly reduced the risk of hospitalisation or death by 70% compared to placebo. Casirivimab and imdevimab also significantly shortened the duration of symptoms by four days.

“With the increasing number of Covid-19 infections in India, Roche is committed to doing everything we can to minimise hospitalisations and ease pressure on healthcare systems. This is where neutralising antibody cocktails like casirivimab and imdevimab can play a role in the fight against COVID-19 and in the treatment of high-risk patients before their condition worsens. We are thankful to the CDSCO for granting a EUA for casirivimab and imdevimab. This outpatient treatment for COVID-19 will be complementary to the ongoing vaccination drive and support our fight against the pandemic in India,” V Simpson Emmanuel, MD, Roche Pharma India said.

Commenting on the partnership, Umang Vohra, MD & Global CEO Cipla said, “We are deeply committed to exploring all possible treatment options and being at the forefront in our fight against Covid-19. This partnership with Roche is a significant step in enabling access to promising treatments in furtherance to our purpose of the Caring for Life.”

Cipla will market and distribute the product in India by leveraging its solid distribution strengths across the country. The drug will be available through leading hospitals and Covid treatment centers, he added.

Casirivimab and Imdevimab are human immunoglobulin G-1 (IgG1) monoclonal antibodies produced by recombinant DNA technology. The production process for this biologic medicine is very complex and Roche as one of the largest biologics manufacturers in the world was selected by its partner Regeneron to expand worldwide production capacity. Roche will do everything to ensure equitable distribution across the globe, however initial local demand may far exceed the supplies the company will be able to provide, Roche Pharma India’s MD V Simpson Emmanuel also said.

Elaborating about the mechanism of action, he informed: “Monoclonal antibodies are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as viruses. Casirivimab and imdevimab are monoclonal antibodies that are specifically directed against the spike protein of SARS-CoV-2, designed to block the virus’ attachment and entry into human cells.

Thanks to its specific engineering of two neutralising antibodies that bind to different parts of the virus spike, the Casirivimab and imdevimab cocktail remains efficacious against widest spread variants and reduces the risk of losing its neutralisation potency against new emerging variants.” On dosage, he added, “Casirivimab and Imdevimab is approved at a combined dose of 1200 mg (600 mg of each drug) administered by intravenous infusion or subcutaneous route. It has to be stored at 2 °C to 8 °C.”
