Safety, pharmacokinetics, and immunogenicity of a co-formulated cocktail of three human monoclonal antibodies targeting Ebola virus glycoprotein in healthy adults: a randomised, first-in-human phase 1 study.

Background: REGN3470-3471-3479 is a co-formulated cocktail of three human monoclonal antibodies targeting three non-overlapping epitopes on Ebola virus. We investigated safety, tolerability, pharmacokinetics, and anti-drug antibodies in healthy adults.

Methods: This randomised, double-blind, placebo-controlled, dose-escalation study was done at a phase 1 unit in the USA.
