Shorter, all-oral treatment for multidrug-resistant tuberculosis

DRAMATIC Phase 2 Duration Randomized MDR-TB Treatment Trial

What this research studies

If I join, I would be randomized to one of four different treatment lengths of an all-oral combination that includes newer drugs like bedaquiline and delamanid, with linezolid given only during the first 8 weeks. The trial is partially blinded, happens at multiple sites, and is a Phase 2 effort designed to find the shortest duration that still cures MDR-TB. The regimen avoids injectable drugs and pyrazinamide (PZA) to reduce toxicity, and animal studies suggest the combination could work. The study team will monitor safety and cure rates over time to decide which treatment lengths are effective.

Who could benefit from this research

Good fit: People diagnosed with multidrug-resistant tuberculosis (MDR-TB) who are eligible for an all-oral treatment plan and can attend study visits are the ideal candidates.

Not a fit: People without MDR-TB, or whose TB is resistant to the study drugs or who cannot take oral medications or complete follow-up, are unlikely to benefit.

Why it matters

Potential benefit: If successful, this could shorten how long people need treatment and lower the risk of toxic side effects from current regimens.

How similar studies have performed: Newer all-oral drugs like bedaquiline and delamanid have shown promise, but using a randomized multi-duration design to pick the shortest safe course is a novel approach.
