The U.S. National Institutes of Health (NIH) said on Wednesday that it had started a clinical trial to evaluate Japan’s Shionogi & Co. Ltd.’s experimental oral antiviral drug to treat COVID-19.

Regulators in Japan had previously denied emergency approval for the Shionogi pill, saying they wanted to see more data on its effectiveness. There were also concerns the drug could pose risk to pregnancies, based on results from animal studies.
