Doctors in Germany said on Wednesday a patient infected with Ebola had recovered after they had treated him with an experimental drug initially designed to treat vascular problems and help heart attack patients.

Doctors at the Frankfurt University Hospital said the patient, who was medically evacuated to Frankfurt after working with Ebola victims in Sierra Leone, recovered after receiving the drug called FX06, developed by scientists at the Vienna General Hospital in Austria.

The patient, whose immune system had been weakened by the virus, was still hospitalized, the medics told reporters at a news conference, and would spend more time in Frankfurt until he regained his strength.
