Use of ivermectin in the treatment of Covid-19: a pilot trial
et al., Toxicology Reports, doi:10.1016/j.toxrep.2021.03.003, NCT04431466 (history)
Very small RCT with 4 control patients and 28 ivermectin patients split across 3 different dosage levels, showing lower (non-statistically significant) ICU admission with treatment. Authors suggest that ivermectin for SARS-CoV-2 is safe and reduces symptoms and viral load, and that the antiviral effect appears to be dose-dependent. NCT04431466 (history).Retraction/censorship: this paper appears to have been censored at the request of the journal's founding editor [pubmed.ncbi.nlm.nih.gov]. An external review is mentioned but is not provided, and there is no reply from the authors, or indication that the authors were notified. Conclusions in this study are limited due to the small size, however we should consider all information in the context of the full body of research.
