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 Pulmonary MDR-TB

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

• Status: Recruiting
• Conditions: Multidrug-Resistant Tuberculosis
• Intervention / Treatment: Drug: Bedaquiline (TMC207); Drug: Background Regimen (BR)

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.

• Participants must be starting the initial MDR-TB treatment at baseline or have started an MDR-TB treatment within 12 weeks of baseline 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

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
• Participant tested positive for Human Immunodeficiency Virus (HIV) for the first time at screening. In addition, participants aged <2 years and participants who are being breastfed or were breastfed within the last 8 weeks before screening will be excluded if the mother has tested positive for HIV
• 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 a history of risk factors for Torsade de Pointes, example heart failure, hypokalemia, known personal or family history of Long QT Syndrome, and untreated hypothyroidism

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.	120 weeks
Maximum Plasma Concentration (Cmax)	The Cmax is the maximum plasma concentration.	Week 2 and 12
Time to Reach Maximum Plasma Concentration (Tmax)	The Tmax is time to reach the maximum plasma concentration.	Week 2 and 12
Minimum Plasma Concentration (Cmin)	The Cmin is the minimum plasma concentration.	Week 2, 12 and 24
Area Under the Plasma Concentration-time Curve From the Time of Dose Administration up to X Hours (AUCtime-h)	AUCtime-h is the area under the plasma concentration-time curve from the time of dose administration up to X hours.	Week 2, 12 and 24
Elimination Half-life (t1/2)	Elimination half-life (t [1/2]) is associated with the terminal slope (lambda [z]) of the semi logarithmic drug concentration-time curve, calculated as 0.693/lambda(z). Lambda(z) is first-order rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve.

Volume of Distribution (Vd)	Volume of distribution is calculated as Dose divided by Lambda(z) multiplied by AUC(infinity). The AUC (infinity) is the area under the plasma concentration-time curve from time zero to infinite time.	Day 1, week 2, 4,6,8,12,16,20,24,28,32,40,48,60,72,84,96,108,120
Apparent Clearance (CL)	Apparent clearance is calculated as Dose/AUC (infinity). The AUC (infinity) is the area under the plasma concentration-time curve from time zero to infinite time.	Day 1, week 2, 4,6,8,12,16,20,24,28,32,40,48,60,72,84,96,108,120

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants with Favorable Treatment outcome (Sustained Positive Clinical Cure)	Sustained Positive Clinical Cure is defined as the percentage of participants with favorable treatment outcome at Week 24 and at study end.	Week 24, Week 120 (end of study)
Time to First Confirmed Sputum Culture Conversion, to acid-fast bacilli (AFB) smear conversion, or Other Microbiology Specimen Sample	Culture conversion is defined as 2 consecutive negative cultures in the Mycobacteria Growth Indicator Tube (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. AFB smear conversion is defined as 2 consecutive negative AFB smear at least 25 days apart.	Baseline (Day 1) up to Week 120
