WHO Ends Hydroxychloroquine Arm of its Solidarity Trial

June 19, 2020

The World Health Organization (WHO) has ended the hydroxychloroquine arm of its multinational Solidarity trial aimed at finding effective COVID-19 treatments.

The decision was made based on data from that trial and from Oxford University’s RECOVERY trial, which showed that the antimalarial did not reduce mortality in hospitalized COVID-19 patients compared to standard of care.

The WHO said the decision does not apply to the use or evaluation of hydroxychloroquine as a prophylaxis treatment in people exposed to COVID-19.
