What this research studies

If you have multidrug-resistant tuberculosis (MDR-TB), this trial could randomize you to one of four treatment lengths of an all-oral drug combination including bedaquiline, delamanid, levofloxacin, and a limited 8-week course of linezolid. The regimen avoids pyrazinamide and injectable drugs and limits linezolid to the early treatment period to reduce nerve damage risk. The trial is partially blinded, takes place at multiple clinical centers, and uses a novel "duration-randomization" design that compares different fixed treatment lengths together to find the shortest effective course. Animal data support the drug combination, and the study follows participants for safety and cure outcomes.

Who could benefit from this research

Good fit: Adults with laboratory-confirmed multidrug-resistant pulmonary tuberculosis who meet the study's medical and safety criteria would be the intended participants.

Not a fit: People whose TB is resistant to the study drugs or who cannot safely take the medications are unlikely to be helped by this trial.

Why it matters

Potential benefit: If successful, the regimen could cure MDR-TB with a shorter, all-oral course that has less toxicity than current long treatments.

How similar studies have performed: Some component drugs and animal studies have shown promise, but shortening fixed treatment durations in humans is not yet proven and the duration-randomization design is a new approach.
