An experimental monoclonal antibody-based therapy, administered to two American healthcare workers who contracted Ebola in Liberia, illustrates the risks physicians and patients are willing to take to stop the often fatal infection.
Forbes reported that the product, called ZMapp, is a “three-antibody cocktail” that “provides an artificial immune response against sugar-tagged proteins on the outside of the Ebolavirus.” So far it has not been tested in Phase I clinical trials, making the US patients guinea pigs for the treatment.
Ars Technica tracked down publications related to the therapy, which was initially developed by Mapp Biopharmaceutical. According to Ars, “in the researchers’ most recent published work, from about a year ago, they used it on macaques that were already developing fevers as a result of the infection. Nearly half of the animals survived, while the infection was completely fatal in the control group.”
When the two Americans fell ill in Liberia, their humanitarian groups appealed to US health ...
