Not sure if this was discussed. Prob paywalled but I copied the first part of it
Three Massachusetts hospitals have received approval to launch the first US clinical trial of a Japanese flu drug that could be used to treat COVID-19, according to one doctor involved in the effort.
The trial — which will take place at Massachusetts General Hospital, Brigham and Women’s Hospital, and UMass Memorial Medical Center in Worcester — was approved by the federal Food and Drug Administration Tuesday. The small, randomized trial of the Japanese antiviral drug favipiravir will look to study its effectiveness as a treatment for patients infected with the coronavirus, according to doctors involved in the study.
The Japanese government has touted the drug, known by the brand name Avigan, as a possible treatment for COVID-19, the disease caused by the coronavirus. Medical authorities in China have called the drug “clearly effective” in treating coronavirus patients after conducting two clinical trials.
