What this research studies

If you join, you would be randomly assigned to one of four different treatment lengths of an all-oral regimen that includes bedaquiline, delamanid, levofloxacin, and a limited course of linezolid. The regimen avoids injectable drugs and pyrazinamide and limits linezolid to the first eight weeks to reduce nerve-related side effects. Researchers will compare outcomes across the four durations together to identify the shortest length that still clears infection, with regular safety and effectiveness monitoring. The multicenter, partially blinded Phase 2 trial is led by UCSF and is supported by animal data suggesting the drug combination can work.

Who could benefit from this research

Good fit: Ideal candidates are adults diagnosed with multidrug-resistant tuberculosis who meet the trial's medical and safety criteria and can attend a participating clinic for treatment and follow-up.

Not a fit: People who are pregnant, have medical contraindications to the study drugs, or cannot commit to study visits may not be eligible or may not benefit from participation.

Why it matters

Potential benefit: If successful, this could offer people with MDR-TB a shorter, safer treatment that is easier to complete.

How similar studies have performed: Some drugs in the regimen (bedaquiline, delamanid) have shown activity against MDR-TB, but the specific all-oral, fixed-duration approach using duration-randomization is novel and not yet proven.
