Background and Objectives: Researchers all around the world are working hard to find an effective treatment for the new coronavirus 2019 We performed a comprehensive systematic review to investigate the latest clinical evidence on the efficacy and safety of treatment with Remdesivir in hospitalized patients with COVID-19 Materials and Methods: We performed a systematic search in Pubmed, Embase, Web of Science, Google scholar and MedRxiv for relevant observational and interventional studies The outcomes measures were mortality rates, improvement rates, time to clinical improvement, all adverse event rates and severe adverse event rates Results: Three randomized controlled trials and 2 cohort studies were included in our study In the 2 cohort studies, patients received Remdesivir for 10 days 2 RCTs evaluated 10-day efficacy of treatment with Remdesivir versus placebo group and the other RCT compared its 5-day regimen versus 10-day regimen Visual inspection of the forest plots revealed that the efficacy of Remdesivir was not much different in reducing 28-day mortality versus 14-day mortality rates Besides, 10-day treatment regimen overpowered 5-day treatment and placebo in decreasing time to clinical improvement All adverse event rates did not have a significant difference;however, severe adverse event rate was lower in the 5-day Remdesivir group compared to the 10-day and placebo groups Conclusion: 5-day course of Remdesivir therapy in COVID-19 patients is probably efficacious and safe, and patients with-out invasive mechanical ventilation benefit the most Treatment can be extended to 10 days if satisfactory improvement is not seen by day 5 Most benefits from Remdesivir therapy take place in the first 14 days of the start of the treatment
