Among the 1,500 patients in the study, he said, Ivermectin showed “no effect whatsoever” on the trial’s outcome goals — whether patients required extended observation in the emergency room or hospitalization.

“In our specific trial,” he said, “we do not see the treatment benefit that a lot of the advocates believe should have been” seen.

The study’s results on Ivermectin haven’t been formally published or peer-reviewed. Earlier peer-reviewed results from the Together Trial related to the antimalarial drug hydroxychloroquine, which had been touted as a miracle treatment for COVID by then-President Trump, were published in April; they showed no significant therapeutic effect on the virus.

The findings on Ivermectin are yet another blow for advocates promoting the drug as a magic bullet against COVID-19. Ivermectin was developed as a treatment for parasitical diseases, mostly for veterinarians, though it’s also used against some human parasites.
