Japan plans to authorize Thursday the antiviral drug remdesivir developed by US firm Gilead Sciences, to treat coronavirus patients, the government said, with an eye to approving another medication Avigan this month.
This would make Japan the second country to approve the drug after US regulators authorised it on Friday for emergency use against severe cases of COVID-19.
The US gave the go-ahead after a major clinical trial showed remdesivir, originally developed to treat Ebola, shortened the time to recovery in some patients by a third.
“If there is no problem we hope to swiftly approve (the drug) today” at the health ministry’s regulatory panel, top government spokesman Yoshihide Suga told reporters.
Remdesivir, which is administered by injection, was already available to some patients who enrolled in clinical trials around the world.
As for Avigan, developed by Japanese firm Fujifilm Toyama Chemical, Suga said the government “aims to approve it this month” if a clinical trial involving 100 patients proves effective.
The drug, whose generic name is favipiravir, was approved for use in Japan in 2014 but only in flu outbreaks that are not being effectively addressed by existing medications.
It is not available on the market and can only be manufactured and distributed at the request of the Japanese government.
Favipiravir, which can be taken orally as a pill, works by blocking the ability of a virus to replicate inside a cell.
Remdesivir incorporates itself into the virus’s genome, short-circuiting its replication process.
Avigan has been shown in animal studies to affect foetal development, meaning it is not given to pregnant women.
