Ethical issues
Dr Peter Horby, of the Centre for Tropical Medicine and Global Health at the University of Oxford, said the first trials could begin in West Africa as early as November.
"We want to evaluate these carefully, properly, in affected countries in West Africa," he told the BBC.
"For the next one or two weeks we'll be doing site assessments and we'll be working with the WHO [World Health Organization] on identifying which drugs to prioritise, and then there'll be a number of steps in setting up the systems - getting ethical approval through the countries and getting community participation and agreement to run the trials.
"Currently our wish is that we would hope to be able to enrol some patients sometime in November - that would be extremely quick by most clinical trial standards."
Dr Jeremy Farrar, director of the Wellcome Trust, said therapeutics alone were not an answer.
"The answer really is public health interventions," he said. "But I do think vaccines and drugs are going to play a role."
Meanwhile, more information on the spread and likely scale of the epidemic has emerged.
Research published in the New England Journal of Medicine suggests by early November there will have been nearly 20,000 cases.
It also found death rates were higher than previously reported at about 70% of all cases.
