RCT with 77 nitazoxanide, 70 sofosbuvir/ledipasvir, and 73 SOC patients in Egypt, showing faster viral clearance with nitazoxanide and with sofosbuvir/ledipasvir. There was no mortality or progression to severe COVID-19 or ICU admission. Nitazoxanide 500mg qid for 14 days. SOC included vitamin C and zinc.
