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

Bedaquiline (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) 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.
