Mixed Results in Other Studies
“Our negative results on the anti-viral efficacy of HCQ obtained in this trial are on the contrary to the encouraging in-vitro results and to the recently reported promising results from a non-randomized trial with 36 COVID-19 patients,” the authors write.
However, the 36-patient trial to which they refer has since been called into question, as previously reported by Retraction Watch.
Despite lack of clear evidence of benefit, HCQ is recommended off label for the treatment of COVID-19 by the Chinese National guideline, and the US Food and Drug Administration has issued an emergency-use authorization for the treatment of adult patients with COVID-19.
By contrast, the Infectious Diseases Society of America recently concluded that because of insufficient data, they could not recommend any particular treatment for patients with COVID-19.
The work was supported by the Emergent Projects of National Science and Technology; the National Natural Science Foundation of China; the National Key Research and Development Program of China; the Shanghai Municipal Key Clinical Specialty; the National Innovative Research Team of High-Level Local Universities in Shanghai; the Shanghai Key Discipline for Respiratory Diseases; the National Major Scientific and Technological Special Project for Significant New Drugs Development; and Key Projects in the National Science and Technology Pillar Program. The authors, Kahlenberg, and Plowe have disclosed no relevant financial relationships.
