Importance: There is no established anti-viral therapy for treating COVID-19 illness.
Objective: To study the usefulness of Ivermectin, an antimicrobial therapy, in COVID-19 outcomes.
Design: An international, multicenter, observational propensity-score matched case-controlled study using prospectively collected data on patients diagnosed with COVID-19 between January 1, 2020 and March 31, 2020.
Setting: An international multi- institutional deidentified healthcare outcomes database.
Participants: Hospitalized patients diagnosed with COVID-19 determined by presence of a positive laboratory finding confirming SARS-CoV-2 infection.
Exposure: Ivermectin (150mcg/Kg) administered once compared with COVID-19 patients receiving medical therapy without ivermectin.
Main Outcome: The principal outcome was to assess the association of ivermectin administration with survival in COVID-19.
Results: The cohort (including 704 ivermectin treated and 704 controls) was derived from 169 hospitals across 3 continents with COVID-19 illness. The patients were matched for age, sex, race or ethnicity, comorbidities and a illness severity score (qSOFA). Of those requiring mechanical ventilation fewer patients died in the ivermectin group (7.3% versus 21.3%) and overall death rates were lower with ivermectin (1.4% versus 8.5%; HR 0.20 CI 95% 0.11-0.37, p<0.0001).
Conclusions and Relevance: The administration of ivermectin during COVID-19 illness in hospitalized patients is associated with a lower mortality and hospital length of stay. These findings require confirmation in randomized controlled trials.
