The World Health Organization (WHO) said on Saturday that it was discontinuing its trials of the malaria drug hydroxychloroquine and combination HIV drug lopinavir/ritonavir in hospitalized patients with COVID-19 after they failed to reduce mortality.
The setback came as the WHO also reported more than 200,000 new cases globally of the disease for the first time in a single day. The United States accounted for 53,213 of the total 212,326 new cases recorded on Friday, the WHO said.
“These interim trial results show that hydroxychloroquine and lopinavir/ritonavir produce little or no reduction in the mortality of hospitalized COVID-19 patients when compared to standard of care. Solidarity trial investigators will interrupt the trials with immediate effect,” the WHO said in a statement, referring to large multicountry trials that the agency is leading.
