Objective: To evaluate different doses of ivermectin in adult patients with mild COVID-19 and to evaluate the effect of ivermectin on mortality and clinical consequences.


Methods: A randomized, double-blind, placebo-controlled, multicenter clinical trial was performed at five hospitals. A total of 180 mild hospitalized patients with COVID-19 confirmed by PCR or chest image tests were enrolled and allocated to six arms including hydroxychloroquine 200 mg twice per day, placebo plus hydroxychloroquine 200 mg twice per day, single dose ivermectin (200 μg/kg), three low interval doses of ivermectin (200, 200, 200 μg/kg), single dose ivermectin (400 μg/kg), and three high interval doses of ivermectin (400, 200, 200 μg/kg). The primary endpoint of this trial was all-cause of mortality or clinical recovery. The radiographic findings, hospitalization and low O2 saturation duration, and hematological variables of blood samples were analyzed.


Results: A total of 16.7% (5/30) and 20.0% (6/30) patients died in arms treated with hydroxychloroquine 200 mg twice per day and placebo plus hydroxychloroquine 200 mg twice per day, respectively, and a reduction in mortality rate in patients receiving ivermectin treatment to 0%, 10%, 0% and 3.3% for arms 1-4 were observed. Risk of mortality was also decreased about 15% in the ivermectin treated arms.


Conclusions: Ivermectin as an adjunct reduces the rate of mortality, time of low O2 saturation, and duration of hospitalization in adult COVID-19 patients. The improvement of other clinical parameters shows that ivermectin, with a wide margin of safety, had a high therapeutic effect on COVID-19.
