Single-dose oral ivermectin in mild and moderate COVID-19 (RIVET-COV): a single-centre randomized, placebo-controlled trial
et al., Journal of Infection and Chemotherapy, doi:10.1016/j.jiac.2021.08.021 (preprint 2/2/2021)
RCT in India with low risk patients, comparing 24mg ivermectin, 12mg ivermectin, and placebo showing non-statistically significant improvements in recovery and PCR+ status (day 5 both arms, day 7 24mg only) with treatment, and showing greater improvement for the higher dose arm. Viral load decline was similar in all arms - absolute values are lower for ivermectin in a dose-dependent manner, however the baseline value for the ivermectin groups was lower, leaving less room for change. There were no deaths or use of mechanical ventilation. There were no serious adverse events. Note that our pre-specified protocol prioritizes clinical outcomes over PCR results. The supplementary appendix is not currently available.
