TOKYO — Japan said Monday it is ready to provide a Japanese-developed anti-influenza drug as a possible treatment for the rapidly expanding Ebola outbreak.
Chief Cabinet Secretary Yoshihide Suga told reporters that Japan can offer favipiravir, developed by a subsidiary of Fujifilm Holdings Corp., at any time at the request of the World Health Organization.
The drug, with the brand name Avigan, was developed by Fujifilm subsidiary Toyama Chemical Co. to treat new and re-emerging influenza viruses, and has not been proven to be effective against Ebola.
Favipiravir was approved by Japan’s health ministry in March for use against influenza. Fujifilm is in talks with the U.S. Food and Drug Administration, through a U.S. partner, Medivector, to prepare for clinical testing of the drug in treating Ebola, company spokesman Takao Aoki said.
He said Ebola and influenza viruses are the same general type, and a similar response can theoretically be expected from Ebola.
Favipiravir inhibits viral gene replication within infected cells to prevent propagation, while other anti-viral drugs often are designed to inhibit the release of new viral particles to prevent the spread of infection, the company said.
The company has enough stock of favipiravir for more than 20,000 patients, Aoki said.
Suga, the Cabinet spokesman, said Japan is watching for a decision by WHO that would provide more details on the use of untested drugs against Ebola. In case of an emergency, Japan may respond to individual requests before any further decision by WHO, he said.
WHO said earlier this month that it is ethical to use untested drugs on Ebola patients given the magnitude of the outbreak.
Several drugs are being developed for the treatment of Ebola. They are still in the early stages and there is no proven treatment or vaccine for the often fatal disease.

Recently, two American doctors recovered from Ebola after being treated with the experimental drug ZMapp, though it was unclear whether they were cured by the drug.
However, a Liberian doctor who was among three Africans to receive ZMapp recently died, the country’s information minister said Monday.
Asked about the drug being offered from Japan, Liberian Information Minister Lewis Brown said, “Although we will continue to emphasize prevention, we remain open to all available curative opportunities.”
Dr. Abraham Borbor, the deputy chief medical doctor at the country’s largest hospital, had been among three Liberians, and the first Africans, who received the experimental drug, ZMapp. Two Americans received the untested drug and survived. A Spaniard infected with Ebola received the treatment but died. There was no update given on the two other Liberians who took doses of the drug.
Borbor “was showing signs of improvement but yesterday he took a turn for the worse,” Information Minister Lewis Brown told The Associated Press. It wasn’t clear if he died late Sunday or on Monday.
Ebola has killed more than 1,400 people across West Africa. There is no proven vaccine or cure for the disease that can cause a grisly death with bleeding from the eyes, mouth and ears.
The virus can only be transmitted through direct contact with the bodily fluids of the sick or from touching victims’ bodies, leaving doctors and other health care workers most vulnerable to contracting it.
