UTMB’s Thomas Geisbert comments on the decision to close down testing in humans of a Tekmira experimental Ebola drug. Geisbert, who has himself tested some of Tekmira’s drugs on monkeys, says that this doesn’t mean that the drug cannot work. Instead, it demonstrates just how difficult it is to test drugs on real patients during epidemics. The news is also shown in Science/AAAS, The Scientist, Tech Times and West Texas News, among others
