Use of ivermectin in the treatment of Covid-19: A pilot trial

Objectives: In this randomized open-label trial pilot study we assessed the antiviral effects and safety of various doses of ivermectin in patients with mild clinical symptoms of COVID-19. Methods: Patients were randomly assigned to receive standard of care (SOC) treatment at hospital admission; SOC...

Methods: Patients were randomly assigned to receive standard of care (SOC) treatment at hospital admission; SOC plus ivermectin 100 mcg/kg; SOC plus ivermectin 200 mcg/kg; or SOC plus ivermectin 400 mcg/kg. The primary assessed endpoint was the proportion of patients who achieved two consecutive negative SARS-CoV-2 RT PCR tests within 7 days of the start of the dosing period. This study was registered at ClinicalTrials.gov (NCT04431466). Results: A total of 32 patients were enrolled and randomized to treatment. SOC treatment together with ivermectin did not result in any serious adverse events. All patients exhibited a reduction in SARS-CoV-2 viral load within 7 days; however, those who received ivermectin had a more consistent decrease as compared to the SOC alone group, characterized by a shorter time for obtaining two consecutive negative SARS-CoV-2 RT PCR tests. Conclusions: Ivermectin is safe in patients with SARS-CoV-2, reducing symptomatology and the SARS-CoV-2 viral load. This antiviral effect appears to depend on the dose used, and if confirmed in future studies, it suggests that ivermectin may be a useful adjuvant to the SOC treatment in patients with mild COVID-19 symptoms.http://www.sciencedirect.com/science/article/pii/S2214750021000445IvermectinCOVID-19SARS-CoV-2
