DRTB-HDT

STRATIFIED HOST-DIRECTED THERAPY

FOR DRUG-RESISTANT  TUBERCULOSIS

Tuberculosis has historically been the most common infectious cause of death globally, surpassed only recently (and presumably temporarily) by the ongoing Covid-19 pandemic. TB treatment is lengthy and often unsuccessful. Most patients are left with impaired lung function and shortened longevity even if cured. This project evaluates two adjunctive host-directed therapies in patients with rifampin-resistant tuberculosis (RIF-R-TB) in a phase 2 clinical trial. RIF-R-TB patients are at increased risk of death, treatment failure, and impaired post-TB lung function. The trial’s two experimental arms add either CC-11050 (a type 4 phosphodiesterase inhibitor that reduces inflammation by increasing cellular levels of cyclic AMP) or metformin (an AMPK activator used to treat diabetes mellitus that alters cellular metabolism) to standard RIF-R-TB treatment. A control arm receives standard RIF-R-TB treatment alone. The experimental arms are each compared individually to the control arm. The study’s two co-primary endpoints examine lung function (FEV1, in a superiority comparison) and sputum culture conversion (the likelihood of sputum culture conversion expressed as a hazard ratio, in a non-inferiority comparison).
