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.
Participant must be a boy or girl, aged from birth (0 months) to less than (<) 18 years at screening. Participants in Cohort 4 who are <6 months of age at screening, gestational age at birth had to be greater than or equal to (>=) 37 weeks
Participant must weigh >3 kilogram (kg) at baseline and be within the 5th and 95th percentiles (inclusive) for the participant's age, based on the World Health Organization (WHO) child growth standards; Body Mass Index (BMI) for age. 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 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
Participant has known or presumed forms of extrapulmonary TB, other than: Lymphadenopathy (peripheral nodes or isolated mediastinal mass without significant airway compression); Pleural effusion or pleural fibrotic lesions
Participant has a significant cardiac arrhythmia that requires medication or risk factors for Torsade de Pointes, example heart failure, hypokalemia, known personal or family history of Long QT Syndrome, and untreated hypothyroidism
Single group
Bedaquiline (TMC207)
DrugBedaquiline (TMC207) oral tablet adult formulation (containing 100 mg bedaquiline (TMC207) per tablet) administered as 400 milligram (mg), once daily, for the first 2 weeks, followed by bedaquiline 200 mg 3 times per week with intakes at least 2 days (48 hours) apart for 22 weeks in cohort 1. Cohort 2, 3 and 4 will receive an age appropriate oral tablet formulation containing 20mg bedaquiline . Bedaquiline tablet administered orally as 200 mg, once daily, for the first 2 weeks, followed by bedaquiline 100 mg 3 times per week with intakes at least 2 days (48 hours) apart for 22 weeks in cohort 2. In Cohort 3, dose of bedaquiline 8 mg/kg qd for the first 2 weeks, followed by bedaquiline 4 mg/kg times weekly (TIW) with intakes at least 2 days (48 hours) apart for 22 weeks will be administered. In cohort 4, bedaquiline (TMC207) qd for the first 2 weeks, followed by bedaquiline TIW with intakes at least 2 days (48 hours) apart for 22 weeks.
Background Regimen (BR)
DrugBackground Regimen (BR) of Multidrug Resistant Tuberculosis (MDR-TB) medications will be dosed according to World Health Organization (WHO) guidelines, National Tuberculosis Program (NTP) guidelines and current standard of care at the site.
Number of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)
An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Maximum Plasma Concentration (Cmax)
The Cmax is the maximum plasma concentration.
Time to Reach Maximum Plasma Concentration (Tmax)
The Tmax is time to reach the maximum plasma concentration.
Minimum Plasma Concentration (Cmin)
The Cmin is the minimum plasma concentration.
Percentage of Participants with Favorable Treatment outcome (Sustained Clinical Cure)
Sustained Clinical Cure is defined as the percentage of participants with favorable treatment outcome at Week 24 and at study end.
Time to First Confirmed Mycobacteria Growth Indicator Tube (MGIT) Culture Conversion of Clinical Specimen Sample
Culture conversion is defined as 2 consecutive negative cultures in the MGIT system at least 25 days apart with the last culture within the analysis window, unless a repeat microbiology sample (eg, lymph node biopsy) cannot be obtained.
Time to Acid-Fast Bacilli (AFB) Smear Conversion of Clinical Specimen Sample
AFB smear conversion is defined as 2 consecutive negative AFB smear at least 25 days apart.
