NIAID releases additional data validating BenevolentAI’s hypothesis for baricitinib as a treatment for COVID-19 patients in large-scale randomised control trial

BenevolentAI, the leader in the application of AI and machine learning to re-engineer drug discovery and development, is pleased to report additional positive data has been released from the large scale randomised ACTT-2 clinical trial, sponsored by the National Institute of Allergy and Infectious Diseases (NIAID). 

The latest data provides a more detailed analysis of the improved clinical outcomes of hospitalised COVID-19 patients taking baricitinib. This data further validates the AI-derived hypothesis of baricitinib as a treatment for COVID-19, first published by BenevolentAI in The Lancet on February 4, 2020. 


The key findings showed:
  • Odds of improvement in clinical status at day 15 were 30% greater in patients being treated with baricitinib in combination with remdesivir, compared with remdesivir alone (statistically significant). 
  • The largest benefits were observed in patients requiring supplemental oxygen and those needing high-flow oxygen/non-invasive ventilation.
  • There was a 35% lower mortality rate overall in the group taking baricitinib (5.1% vs 7.8%), but the separation was not statistically significant.
  • The reduction in mortality was more pronounced for patients receiving oxygen, as mortality at Day 29 was 60% lower for those on supplemental oxygen, and 43% lower for those on high-flow oxygen/non-invasive ventilation.
  • As previously reported, the trial met the primary endpoint of reducing time to recovery (discharge from hospital) by one day compared to remdesivir alone, which is statistically significant. 

The ACTT-2 randomised control trial included more than 1,000 patients and began on May 8 to assess the efficacy and safety of baricitinib plus remdesivir versus remdesivir in hospitalised patients with COVID-19. No new safety signals were observed for baricitinib-treated patients in this study. 

NIAID authors are working to have the full analysis completed, and a peer-reviewed manuscript will be made available soon.

Note to editors: Baricitinib is approved for the treatment of rheumatoid arthritis and other diseases.  It is administered orally and has been used to treat COVID-19 patients in more than 14 clinical trials worldwide including the randomised clinical trials by the NIAID and Eli Lilly. BenevolentAI’s research on baricitinib as a treatment for COVID-19 has been published in The Lancet, The Lancet Infectious Diseases, and EMBO Molecular Medicine
