The anti-leprosy drug clofazimine has been shown to have antimicrobial activity against Mycobacterium tuberculosis and has been associated with treatment-shortening activity in both clinical and preclinical studies of TB chemotherapy. However, a reported lack of early bactericidal activity (EBA) in TB patients has raised questions regarding the usefulness of clofazimine as an anti-TB drug. Our objective was to systematically evaluate the EBA of clofazimine in vitro and in vivo to provide insight into how and when this drug exerts its antimicrobial activity against M. tuberculosis.
