Public health officials announced Monday they had gathered enough preliminary data to determine that 2 of the 4 investigational treatments for Ebola performed better than the others. The current trial in the Democratic Republic of the Congo has been dropped to focus on a new extension trial for the 2 monoclonal antibodies.

Why it matters: There are currently no FDA-approved treatments for Ebola. Researchers testing drugs during the DRC's largest outbreak found a cocktail of 3 antibodies called REGN-EB3 was most effective, followed closely by monoclonal antibody 114.

One year on — No end in sight for deadly Ebola outbreak

One year ago today, the Democratic Republic of the Congo declared an outbreak of Ebola. Since then, more than 1,800 people have died, the virus has been carried to the large city of Goma on the border of Rwanda and to nearby Uganda, and violence has killed health workers.

The big picture: Politics, violence and community suspicion are thwarting efforts to contain the virus, which shows no signs of abatement. Experts say this cycle could easily spiral out of control.
