Conventional trials to study efficacy by exposure of humans to the pathogen are obviously not feasible in this case. For such situations, the FDA has established the "Animal Efficacy Rule" allowing limited licensure to be approved on the basis of animal model studies that replicate human disease, combined with evidence of safety. A number of experimental treatments are being considered for use in the context of this outbreak, and are currently or will soon undergo clinical trials.[8] A distributed computing project, Outsmart Ebola Together, has been launched by World Community Grid in collaboration with the Scripps Research Institute to help find chemical compounds to fight the disease.
