Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
BackgroundIvermectin, an anti-parasitic agent, also has anti-viral properties. Our aim was to assess whether ivermectin can shorten the viral shedding in patients at an early-stage of COVID-19 infection. MethodsThe double-blinded trial compared patients receiving ivermectin 0{middle dot}2 mg/kg for 3 days vs. placebo in non-hospitalized COVID-19 patients. RT-PCR from a nasopharyngeal swab was obtained at recruitment and then every two days. Primary endpoint was reduction of viral-load on the 6th day (third day after termination of treatment) as reflected by Ct level>30 (non-infectious level). The primary outcome was supported by determination of viral culture viability. ResultsEighty-nine patients were eligible (47 in ivermectin and 42 in placebo arm). Their median age was 35 years. Females accounted for 21{middle dot}6%, and 16{middle dot}8% were asymptomatic at recruitment. Median time from symptom onset was 4 days. There were no statistical differences in these parameters between the two groups. On day 6, 34 out of 47 (72%) patients in the ivermectin arm reached the endpoint, compared to 21/ 42 (50%) in the placebo arm (OR 2{middle dot}62; 95% CI 1{middle dot}09-6{middle dot}31). In a multivariable logistic-regression model, the odds of a negative test at day 6 was 2.62 time higher in the ivermectin group (95% CI 1{middle dot}06-6{middle dot}45). Cultures at days 2 to 6 were positive in 3/23 (13{middle dot}0%) of ivermectin samples vs. 14/29 (48{middle dot}2%) in the placebo group (p=0{middle dot}008). ConclusionsThere were significantly lower viral loads and viable cultures in the ivermectin group, which could lead to shortening isolation time in these patients. The study is registered at ClinicalTrials.gov NCT 044297411.
