Hydroxychloroquine did not prevent Covid-19 in the first controlled clinical trial.
The malaria drug hydroxychloroquine did not prevent Covid-19 in a rigorous study of 821 people who had been exposed to patients infected with the virus, researchers from the University of Minnesota and Canada are reporting Wednesday.
The study was the first controlled clinical trial of hydroxychloroquine, a drug that President Trump has repeatedly promoted and said he had taken himself to try to ward off the virus.
Conducted in the United States and Canada, the trial was the first to test whether the drug could prevent illness in people who have been exposed to the virus. This type of study, in which patients are picked at random to receive either an experimental treatment or a placebo, is considered the most reliable way to measure the safety and effectiveness of a drug.
The take-home message for the general public is that if youre exposed to someone with Covid-19, hydroxychloroquine is not an effective post-exposure, preventive therapy, the lead author of the study, Dr. David R. Boulware of the University of Minnesota, said in an interview.
The results are being published in The New England Journal of Medicine.
