Official Title

Bedaquiline Roll-out Evidence in Contacts and People Living With HIV to Prevent TB (BREACH-TB)

Brief Summary

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

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.

• Tuberculosis, Latent

• Bedaquiline
• Isoniazid, rifapentine
• Levofloxacin

Eligibility Criteria

INCLUSION CRITERIA

For Index Patient

• Any age

• A diagnosis of bacteriologically proven pulmonary TB
• Initiated on treatment for pulmonary TB within the past 90 days
• Have at least one close contact that is likely to be eligible for the study

For PLHIV Indication

Individuals must meet all of the following inclusion criteria to participate in this study:

• On a dolutegravir-based or other approved integrase inhibitor antiretroviral therapy (ART) regimen that does not interact with bedaquiline or rifapentine.

  • If on a protease inhibitor-based ART regimen, a participant can be enrolled following a 5-day washout with switch to a dolutegravir-based regimen prior to enrollment. A 14-day washout is required for efavirenz-based ART regimen with switch to a dolutegravir-based regimen prior to enrollment
  • If a participant is not currently on ART or is ART-naïve, the participant must have started a dolutegravir-based ART regimen prior to Enrollment.

• PLHIV who meet criteria for a TBD close contact should be enrolled under the close contact indication

For Close Contact Indication (DS- or RR-TB Index Patient)

• Definition of Close Contact (either/or):

  o Lives or lived in the same dwelling unit or plot of land and shares or has shared the same housekeeping arrangements as the Index Patient for one or more nights ≤ 90 days prior to the Index Patient starting TB treatment

  o Has shared more than four hours of indoor airspace with the Index Patient during any one-week period ≤ 90 days prior to the Index Patient starting TB treatment. This may include indoor airspace within or outside the home.

• Close contacts must be in one of the following high-risk groups:

  • All children 0 to <5 years old at the time of Enrollment, regardless of LTBI or HIV status
  • Adults, adolescents, and children ≥5 years of age who are TBI test positive (either skin test positive* or IGRA-positive) and whose HIV status is negative, indeterminate, or unknown.
  • Adults, adolescents, and children ≥5 years of age who have a documented HIV infection regardless of TBI test status.

Universal Enrollment Inclusion Criteria for PLHIV and Close Contacts of DS- or RR-TB Index Patient

A. Ability and willingness of participant (and/or parent/guardian) to provide informed consent (and assent, as applicable)

B. Documentation of HIV Status

For participants >=18 months of age known to be PLHIV:

• Certified copy of HIV clinic card or
• Certified copy of HIV testing that includes date, assay used and result

For participants <18 months of age who have never tested, or previous HIV test result was indeterminate, unknown, or negative more than three months prior to screening and/or result is not available:

• HIV-1 testing should be performed per Section 5.4.5 (HIV-1 Testing) during the study screen period.

For participants <18 months known to be CLHIV:

• Certified copies of HIV DNA and/or RNA testing that includes date, assay used, and result

For participants <18 months who have never tested, or previous HIV test result was indeterminate, unknown, or negative more than three months prior to screening and/or result is not available:

• HIV-1 testing should be performed per Section 5.4.5 (HIV-1 Testing) during the study screen period

C. Documentation of ART

• All PLHIV (for PLHIV indication and CC that are PLHIV) must be on a dolutegravir-based or other approved integrase inhibitor ART regimen that does not interact with bedaquiline or rifapentine.
• If on a protease inhibitor-based ART regimen, a participant can be enrolled following a 5-day washout with switch to a dolutegravir-based regimen prior to enrollment. A 14-day washout is required for efavirenz-based ART regimen with switch to a dolutegravir-based regimen prior to enrollment.
• If a participant is not currently on ART or is ART-naïve, they must have started a dolutegravir-based ART regimen prior to Enrollment.

• Creatinine clearance ≥ 29 ml/min
• Serum potassium at or above the lower limit of normal
• Serum magnesium at or above the lower limit of normal
• Serum calcium at or above the lower limit of normal
