An experimental Ebola drug healed all 18 monkeys infected with the deadly virus in a study, boosting hopes that the treatment might help fight the outbreak raging through West Africa – once more of it can be made.
The monkeys were given the drug, ZMapp, three to five days after they were infected with the virus and when most were showing symptoms. That is several days later than any other experimental Ebola treatment tested so far.
The drug also completely protected six other monkeys given a slightly different version of it three days after infection in a pilot test. These two studies are the first monkey tests ever done on ZMapp.
“The level of improvement was utterly beyond my honest expectation,” said one study leader, Gary Kobinger of the Public Health Agency of Canada in Winnipeg.
“For animal data, it’s extremely impressive,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, which had a role in the work.
