Pharmacokinetic Study to Evaluate Anti-mycobacterial Activity of TMC207 in Combination With Background Regimen (BR) of Multidrug Resistant Tuberculosis (MDR-TB) Medications for Treatment of Children/Adolescents With Pulmonary MDR-TB

June 4, 2026 updated by: Janssen Research & Development, LLC

A Phase 2, Open-label, Multicenter, Single-arm Study to Evaluate the Pharmacokinetics, Safety, Tolerability and Anti-mycobacterial Activity of TMC207 in Combination With a Background Regimen (BR) of Multidrug Resistant Tuberculosis (MDR-TB) Medications for the Treatment of Children and Adolescents 0 Months to <18 Years of Age Who Have Confirmed or Probable Pulmonary MDR-TB

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (explores what the body does to the drug), and anti-mycobacterial activity of bedaquiline (TMC207) in children and adolescents (0 months to less than [<] 18 years of age) diagnosed with confirmed or probable pulmonary multidrug resistant tuberculosis (MDR-TB), in combination With a Background Regimen (BR) of MDR-TB Medications.

Study Overview

Detailed Description

This is an open-label (all people know the identity of the intervention), multicenter (when more than one hospital or medical school team work on a medical research study) and Phase 2 study. The study will consist of a screening phase, a 24-week open-label treatment phase during which all participants will receive bedaquiline (TMC207) in combination with a BR of MDR-TB medications, and a 96-week follow-up phase. Upon completion of the 24-week treatment with bedaquiline, all participants will continue to receive their BR under the care of the investigator. The total study duration will be 120 weeks for each participant. There will be 4 age based cohorts in this study. Cohort 1: greater than or equal to (>=) 12 to less than (<) 18 years of age; Cohort 2: >=5 to <12 years of age; Cohort 3: >=2 to <5 years of age; Cohort 4: 0 months to <2 years of age. Participants in Cohorts 1 and 2 will be enrolled concurrently followed by sequential enrollment of Cohorts 3 and 4. An internal safety monitoring group will review safety and pharmacokinetic data from each cohort to determine subsequent cohort enrollment and dose. Participants' safety will be monitored throughout the study.

In Cohorts 3 and 4, weight for height/length may be used instead of BMI for age according to the local standard of care. Per WHO guidance, for participants aged < 2 years in Cohort 4, length will be used to calculate the BMI instead of height
  • For Cohorts 1 and 2 only: Heterosexually active girls may participate if they are of non-childbearing potential, or if they are using effective birth control methods and are willing to continue practicing birth control methods throughout Multidrug Resistant Tuberculosis (MDR-TB) treatment and for 6 months after stopping TMC207 treatment, or if they are non-heterosexually active or willing to practice sexual abstinence throughout MDR-TB treatment
  • For Cohorts 1 and 2 only: Boys who engage in sexual activity that could lead to pregnancy of the female partner must use at minimum a male condom throughout MDR-TB treatment and for 3 months after stopping TMC207 treatment
  • Participant must have confirmed or probable (clinically diagnosed or presumed) pulmonary and/or non-severe extrapulmonary MDR-TB, including pre-extensively drug-resistant TB (pre- extensively drug resistant [XDR]-TB) or XDR-TB infection, based on the case definitions of pediatric pulmonary and non-severe extrapulmonary TB as described in the International (WHO) guidelines and in accordance with the local standard of care
  • Participants must be starting the initial MDR-TB treatment at Day 1 or have started an MDR-TB treatment within 12 weeks of Day 1 and are willing to modify it if necessary to an acceptable MDR-TB regimen for use with TMC207
  • Participant must be willing to permanently discontinue RMP from at least 7 days before the baseline visit
  • Participant or legally acceptable representative must consent/assent to human Immunodeficiency virus (HIV) testing of the participant. The mother must also consent to testing of her own HIV status, if the potential participant is a child aged <2 years, or if the participant is >= 2 years old and being breastfed or was breastfed within the last 8 weeks before screening, unless the mother had HIV test performed within 1 month prior to screening and documentation of HIV status can be provided. When documented HIV-positive status is available prior to screening for participants in Cohort 4 or their mother, HIV testing for the participant and mother is not required

Exclusion Criteria:

  • Participant has a clinically significant active medical condition or the presence of any concomitant severe illness or rapidly deteriorating health condition, including immune deficiency (except HIV infection), which in the opinion of the investigator would prevent appropriate participation in the study, or that would make implementation of the protocol or interpretation of the study results difficult, or otherwise make the subject a poor candidate for a clinical study
  • Participant is a girl who is pregnant, or breast-feeding, or planning to become pregnant while enrolled in this study or within 6 months after stopping TMC207 treatment
