The WHO on Tuesday recommended using arthritis drugs Actemra from Roche and Kevzara from Sanofi with corticosteroids for COVID-19 patients after data from some 11,000 patients showed they cut the risk of death. … the risk of dying within 28 days for patients getting one of the arthritis drugs with corticosteroids such as dexamethasone is 21%, compared with an assumed 25% risk among those who got standard care. For every 100 such patients, four more will survive, the WHO said.
