NEW ORLEANS (AP) — The quest for a drug to treat Ebola is speeding up. Federal officials have settled on a plan to test multiple experimental drugs at once, in an umbrella study using a single comparison group. They say this will give more Ebola patients a chance to try a treatment and provide quicker answers on which ones work.

Federal Food and Drug Administration officials described the plan Wednesday at a conference of several thousand tropical disease experts in New Orleans.

There is no treatment for Ebola, but several experimental ones have been tried on a few patients, and scientists are eyeing some others that were developed for different conditions and also might fight Ebola.
