ABSTRACT
Purpose: To evaluate the clinical efficacy of including Ivermectin (single dose on day 1 of 400 mug/kg PO) in the standard of care in hospitalized adults with severe COVID-19. Method(s): Double-blinded, parallel, placebo-controlled, single-center, randomized clinical trial. Seventy-five patients were randomly assigned (1:1) to receive standard of care plus ivermectin or placebo and were followed up for 21 days. Primary outcome measure was admission to ICU and secondary outcomes were the requirement of intensive mechanical ventilation (IMV) and in-hospital death. Intention-to-treat analyses, estimated risk differences (RD), and Hazard ratios (HR) with Cox regression were performed. Result(s): Enrollment stopped due to the lack of eligible patients. Thirty-seven patients were assigned to intervention and 38 to placebo. Patients in the ivermectin group were 54.5 years on average, 62.2% were male. Comorbidities were more prevalent in the control group (78.9% vs. 56.8%). There was no difference in the 21-day risk of admission to the ICU between ivermectin (21.6%) and placebo (15.8%) (RD= 5.8%;95%CI: -11.8%-23.5%);neither in the risk of requirement of IMV (18.9% vs 13.2%), mortality (5.4% vs 10.5%) or in adverse events (32.4% vs. 28.9%). Discussion(s): Ivermectin showed no significant benefit in reducing the requirement of ICU, IMV, or mortality for severe COVID-19 patients.Copyright © 2022 Asociacion Colombiana de Infectologia.
