Experimental drug trials

Brincidofovir is not the only drug being considered for use in treating Ebola. Another drug — ZMapp — healed all 18 monkeys infected with the deadly virus in one recent study. Experimental doses of ZMapp also were given to several humans who suffered from Ebola before the manufacturer’s supply ran out months ago. It was not known whether the doses of ZMapp helped the patients who recovered.

A third drug — The TKM-Ebola injection, by Tekmira Pharmaceuticals of Canada — works by blocking genes that help the Ebola virus reproduce and spread. It has been used in at least one patient and is said to be in limited supply.

Other patients have received blood donations from Ebola survivors who had developed antibodies to the virus.
