Zydus Cadila announced on May 26, 2021, that the company is seeking approval from the Drugs Controller General of India (DCGI) to conduct clinical trials of its monoclonal antibody therapy ZRC-3308 (COVIMAB) that can neutralize COVID-19.

Dr Sharvil Patel, Managing Director, Cadila Healthcare in a statement informed that the biological therapy ZRC-3308, a cocktail of two anti-SARS-CoV-2-neutralizing monoclonal antibodies (mAbs) has the potential to address concerns about the progression of the COVID-19 infection.

The company stated in a tweet further said that at this point, we should be exploring more safer and efficacious treatments to fight COVID-19 to reduce patients' discomfort and suffering.

What is monoclonal antibody (mAb) therapy?

•SARS-CoV-2’s spike protein facilitates the virus in entering into the body’s cells. Monoclonal antibodies (mAbs) target epitopes of SARS-CoV-2’s spike protein.

•Single Monoclonal antibody (mAb) therapy targeting SARS-CoV-2’s spike protein has been approved for emergency use in Europe, India, and the US. However, the US FDA had recently withdrawn the authorization when the single mAb-based therapy was found ineffective on the variants.

•In the case of COVIMAB, a cocktail of two monoclonal antibodies (mAbs), the antibodies will target two unique epitopes of SARS-CoV-2’s spike protein. Two mAbs based products have better efficacy at fighting variants compared to single mAb-based products.

•A press release by Zydus Cadila stated that the biological therapy ZRC-3308 has been specifically devised in a way that provides protection for a long time than the currently approved treatments for COVID-19.
