Abstract

BACKGROUND: To investigate whether ivermectin inhibits SARS-CoV-2 proliferation in patients with mild-to-moderate COVID-19 using time to a negative COVID-19 reverse transcription-polymerase chain reaction (RT-PCR) test.

METHODS: CORVETTE-01 was a double-blind, randomized, placebo-controlled study (August 2020-October 2021) conducted in Japan. Overall, 248 patients diagnosed with COVID-19 using RT-PCR were assessed for eligibility. A single oral dose of ivermectin (200 µg/kg) or placebo was administered under fasting. The primary outcome was time to a negative COVID-19 RT-PCR test result for SARS-CoV-2 nucleic acid, assessed using stratified log-rank test and Cox regression models.

RESULTS: Overall, 112 and 109 patients were randomized to ivermectin and placebo, respectively; 106 patients from each group were included in the full analysis set (male [%], mean age: 68.9%, 47.9 years [ivermectin]; 62.3%, 47.5 years [placebo]). No significant difference was observed in the occurrence of negative RT-PCR tests between the groups (hazard ratio, 0.96; 95% confidence interval [CI] 0.70-1.32; p = 0.785). Median (95% CI) time to a negative RT-PCR test was 14.0 (13.0-16.0) and 14.0 (12.0-16.0) days for ivermectin and placebo, respectively; 82.1% and 84% of patients achieved negative RT-PCR tests, respectively.

CONCLUSION: In patients with COVID-19, single-dose ivermectin was ineffective in decreasing the time to a negative RT-PCR test.

Great contribution to the growing amount of data on what works in COVID-19 and what doesnt work. COVID-19 continues to be with us and it's important that we build our arsenal not only of remedies but, most importantly, the data that guide our clinical decision-making. This trial is a helpful contribution in this regard.
