Glenmark Pharmaceuticals has initiated phase-three of clinical trials in India on antiviral tablet Favipiravir for COVID-19 patients, becoming the first company in the country to do so.

The Mumbai-based company had received approval from Drug Controller General of India (DCGI) last month to conduct clinical trials of Favipiravir antiviral tablets for the treatment of COVID-19 patients.

COVID-19 patients from over 10 leading government and private hospitals in India are being enrolled for the study.

The trial completion and study results are expected by July-August this year. Glenmark was the first pharmaceutical company in India to be given an approval by the regulator to conduct Phase 3 clinical trials in India on Favipiravir antiviral tablets for COVID-19 patients.

Favipiravir is a generic version of Avigan of Fujifilm Toyama Chemical Co. Ltd., Japan, a subsidiary of Fujifilm Corporation.

Clinical trials have commenced and over 10 leading government and private hospitals in India are being enrolled for the study. Glenmark estimates study completion by July/August 2020.

As per the approved clinical trial protocol, 150 subjects with mild to moderate COVID-19 symptoms will be randomised in the study in a 1:1 ratio to Favipiravir with standard supportive care or standalone standard supportive care.

Treatment duration is a maximum of 14 days and the total study duration will be a maximum of 28 days from randomisation.

Glenmark has successfully developed the API and the formulations for the product through its inhouse R&D team.

Favipiravir has demonstrated activity against influenza viruses and has been approved in Japan for the treatment of novel influenza virus infections. The molecule if commercialized, will be marketed under the brand name ‘FabiFlu’ in India.

Commenting on this development, Monika Tandon, Vice President & Head, Clinical Development, Global Specialty/Branded Portfolio, Glenmark Pharmaceuticals Ltd., said, “Several health and medical experts, both in and outside of Glenmark are eager to see the effect that Favipiravir has on COVID-19 cases. We believe the study results will be significant as there is currently no effective treatment for the virus.”

She added, “The data we get from these trials will point us in a clearer direction with regard to COVID-19 treatment and management.”

Sujesh Vasudevan, President, India Formulations, Middle East and Africa, Glenmark Pharmaceuticals Ltd. mentioned “Our effort is to launch a treatment for COVID-19 patients as soon as possible and control the spread of the pandemic. We will do all it takes to ensure accessibility of the product across the country if the clinical trials are successful.”

Glenmark was the first pharmaceutical company in India to be given an approval by the regulator to start the trial on COVID-19 patients in India.

As per the approved clinical trial protocol, 150 subjects with mild to moderate COVID-19 will be randomized in the study in a 1:1 ratio to Favipiravir with standard supportive care or standalone standard supportive care. Treatment duration is a maximum of 14 days and the total study duration will be a maximum of 28 days from randomization.

In March, medical experts in China had claimed that the new flu drug Favipiravir is “clearly effective” in treating the COVID-19 coronavirus pandemic.

Patients who took the flu drug recovered quicker and showed greater lung improvement compared with patients not given the drug.
