Antiviral effect of high-dose ivermectin in adults with COVID-19: A proof-of-concept randomized trial
et al., EClinicalMedicine, doi:10.1016/j.eclinm.2021.100959 (Peer Reviewed)
Proof of concept RCT with 30 ivermectin patients and 15 control patients, showing a concentration dependent antiviral activity, but no significant difference in clinical outcomes. There was no significant difference in viral load reduction between groups overall, but a significant difference was found in patients with higher median plasma ivermectin levels (72% vs. 42%, p=0.004). Mean ivermectin plasma concentration levels correlated with viral decay rate (r=0.47, p=0.02). The change in viral load is provided for the <160ng/mL and >160ng/mL groups, but not the overall treatment group. The corrigendum provides individual viral decay rates for computing the overall treatment group viral decay rate. NCT004381884. Authors published a corrigendum: [1].

practical, effective, and safe means should be used. Elimination of COVID-19
is a race against viral evolution. No treatment, vaccine, or intervention is
100% available and effective for all current and future variants. Denying the
efficacy of any method increases the risk of COVID-19 becoming endemic; and
increases mortality, morbidity, and collateral damage. We do not provide
