In October 2014, a French nurse with Ebola virus who was treated with a combination of Avigan and other drugs recovered. Fujifilm said that information was relayed to the Tokyo-based company by the French National Agency for Medicines and Health Products Safety.

The French Institute of Health and Medical Research then carried out a clinical trial on Avigan’s efficacy as a treatment for EVD at four medical institutes in Guinea from December 2014 to May 2015. Based on the trial results, the Guinean government adopted Avigan tablet administration as part of a treatment regimen for EVD.
