UC Davis Health has launched two clinical trials to treat the novel coronavirus. Scientists have begun testing antiviral remdesivir, which was previously tested on Ebola patients. Researchers are also testing sarilumab, which is used to treat rheumatoid arthritis. UC Davis School of Medicine Dean Allison Brashear says there is a critical need to confirm safe and effective treatments for COVID-19. Right now, there are no FDA-approved therapeutic agents to treat people with coronavirus.
