Fujifilm Holdings Corp. shares rose to their highest level in more than six years in Tokyo trading Monday after a French Ebola patient, who was given its Avigan drug with another experimental treatment, was sent home from the hospital.

The company's shares rose 2.8 percent to close at ¥3,499.5, the highest level since July 2008. Fujifilm said last month that Avigan, its influenza drug, was being given to an Ebola patient at a French hospital along with another unidentified medicine.

With no approved Ebola therapies, doctors and international agencies have been forced to test experimental treatments to fight the deadly virus that has killed thousands in West Africa.
