TB Alliance launched a new Pan-Phase 2 clinical trial incorporating elements of Phase 2a, b and c, identified as NC-009, to evaluate the safety and efficacy of a combination of a new experimental compound, TBAJ-876, with pretomanid and linezolid, components of TB Alliance’s BPaL regimen. This regimen has the potential to shorten and improve treatment for both drug-sensitive and drug-resistant tuberculosis (TB)—one of the world’s deadliest infectious diseases. Results from preclinical and Phase 1 studies presented at the Union Conference showed that the new compound, when compared with bedaquiline (a TB medicine in the same drug class), eliminated TB bacteria faster and had a potentially safer profile.
The goal of this clinical trial is to evaluate 3 dose levels of TBAJ876 for 8 weeks in combination with pretomanid and linezolid, compared to 8 weeks of Isoniazid, rifampicin, pyrazinamide and ethambutol (2HRZE), in adult participants with newly diagnosed, smear-positive, pulmonary drug sensitive tuberculosis (DS-TB).
Participants will be treated up to 26 weeks with either:
- TBAJ876 25 mg + pretomanid 200 mg + linezolid 600 mg for 8 weeks followed by HR for 7 to 18 weeks
- TBAJ876 50 mg + pretomanid 200 mg + linezolid 600 mg for 8 weeks followed by HR for 7 to 18 weeks
- TBAJ876 100 mg + pretomanid 200 mg + linezolid 600 mg for 8 weeks followed by HR for 7 to 18 weeks
- Bedaquiline 200 mg + pretomanid 200 mg + linezolid 600 mg for 8 weeks followed by bedaquiline 100 mg + pretomanid 200 mg + linezolid 600 mg for 18 weeks
- Isoniazid (H) + rifampicin (R) + pyrazinamide (Z), ethambutol (E) for 8 weeks followed by HR for 18 weeks (dose based on participant's weight).
