The USFDA had issued an Emergency Use Authorisation (EUA) to Gilead Sciences Inc for remdesivir for the treatment of COVID-19 patients.
Remdesivir is the only USFDA-approved EUA for treatment for adult and paediatric patients hospitalised with suspected or laboratory-confirmed coronavirus infection.
In May, Gilead Sciences Inc extended a voluntary non-exclusive licence to Cipla to manufacture and market generic version of remedisvir called Cipremi.
Cipla said it has been granted regulatory approval by the Drug Controller General of India (DCGI) for restricted emergency use in the country as part of the accelerated approval process considering the urgent and unmet medical need. SUM HRS
