Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A seamless, staged Phase II/III, open-label, multicenter, non-inferiority trial, to compare the efficacy and safety of 4 weeks of bedaquiline (BDQ) versus a a standard regimen for preventing regimen for preventing confirmed or probable tuberculosis disease (TBD) during 72 weeks of follow-up among people living with HIV (PLHIV) and high-risk Close Contacts (CC) of adults with Drug Susceptible (DS) or Rifampin Resistant (RR) TB.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Treating adult, adolescent, child, and pregnant close contacts (CCs) of drug-sensitive tuberculosis (DS-TB) who are high-risk for developing tuberculosis disease (TBD) as well as adult and adolescent people living with HIV (PLHIV) in high-tuberculosis burden regions with bedaquiline (BDQ) will be noninferior in reducing the risk of developing TBD compared with a WHO-recommended rifamycin-containing short-course regimen for TB preventive therapy (TPT).

Treating adult, adolescent, child, and pregnant CCs of rifampin-resistant tuberculosis (RR-TB) who are high-risk for developing TBD with BDQ will be noninferior in reducing the risk of developing TBD compared with levofloxacin.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

A seamless, staged, Phase II/III, open-label, multicenter, noninferiority trial to compare the efficacy and safety of 4 weeks of oral bedaquiline (1BDQ) versus a standard regimen for preventing confirmed or probable tuberculosis disease (TBD) during 72 weeks of follow-up among people living with HIV (PLHIV) and high-risk Close Contacts (CC) of Index Patients with Drug-Susceptible (DS) or Rifampin-Resistant (RR) TB. CCs that are also household contacts will be cluster-randomized by household.

The study will be divided into two stages, with a seamless transition between stages, meaning enrollment into Stage 2 will start while Stage 1 outcomes analyses are ongoing. All recruited patients will be followed up to 72 weeks post randomization.
Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Outcome Assessors
An independent Endpoint Review Committee (ERC), masked to study arm, will adjudicate the incident TB endpoints (both primary and secondary) and, if there are any deaths, determine the cause of death as TB-related or not TB-related.
