Note: All sites must follow all applicable IRB/EC policies and procedures. * Assigned female sex at birth, as determined by the site investigator based on participant and parent/guardian report and available medical records * Age less than 18 years of age at entry Note: Neonates (defined as children who are 28 days of age or younger \[≤28 days of age\]) may be allowed to enroll after CMC and SMC evaluation of safety and PK data at the interim analysis. * Weight greater than or equal to 4 kg at entry * Has confirmed or probable intrathoracic (pulmonary) RR-TB and/or any form of extrathoracic (extrapulmonary) RR-TB (other than stage 2 or 3 TB meningitis, which is exclusionary) * Confirmed intrathoracic (pulmonary) RR-TB, based on chest radiograph and/or symptoms consistent with TB, and/or any forms of extrathoracic TB, with all of the following, as determined by the site investigator based on medical records: * Microbiological confirmation of M. tuberculosis from any clinical specimen by either culture or molecular methods * Rifampicin resistance demonstrated by genotypic (molecular) or phenotypic methods * Documented clinical decision to treat for RR-TB Note: In the case of discrepant genotypic and phenotypic test results (i.e., rifampicin-susceptible by one method and rifampicin-resistant by another), this criterion will be considered to have been met if at least one rifampicin-resistant result is available and the participant is assessed as having RR-TB by the non-study care provider when study staff evaluate the participant for eligibility. * Probable intrathoracic (pulmonary) RR-TB, based on chest radiograph and/or symptoms consistent with TB, and/or any form of extrathoracic TB, with both of the following, as determined by the site investigator based on medical records: * Documented exposure to a source case with bacteriologically-confirmed intrathoracic rifampicin-resistant TB * Documented clinical decision to treat for RR-TB Note: Full resistance profiles may be obtained after study entry. * Initiated an appropriate TB OBR treatment regimen as per routine treatment decision, at least two weeks prior to entry, as determined by the site investigator based on medical records, and is tolerating the regimen well at entry, in the opinion of the site investigator Note: see exclusion criterion below for exclusionary TB medications * Has normal, grade 1, or grade 2 results for all of the following at screening (i.e., from specimens collected within 28 days prior to entry), based on grading per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table; refer to protocol for guidance on severity grading): * Creatinine * Platelets * Absolute neutrophil count * Hemoglobin * Estimated glomerular filtration rate (eGFR; bedside Schwartz formula) Note: Laboratory tests may be repeated during the study screening period (i.e., within 28 days prior to entry), with the latest results used for eligibility determination. * Has normal or grade 1 results for all of the following at screening (i.e., from specimens collected within 28 days prior to entry), based on grading per the DAIDS AE Grading Table (refer to protocol for guidance on severity grading): * Alanine aminotransferase (ALT) * Lipase * Total bilirubin Note: Laboratory tests may be repeated during the study screening period (i.e., within 28 days prior to entry), with the latest results used for eligibility determination. * Has a normal QT interval corrected by Fridericia's formula (QTcF) (mean interval value less than 450 milliseconds, on ECG performed in triplicate) at screening Note: The mean QTcF value obtained from the centralized ECG reading must be used for eligibility determination. * Has a Karnofsky score greater than or equal to 50% for participants 16 years of age and older or Lansky play score greater than or equal to 50% for participants less than 16 years of age, at screening * Does not have severe acute malnutrition, defined below, and has no presence of nutritional edema, based on physical examination, at screening * Severe acute malnutrition is defined as any of the following: * For participants 5 years of age and younger: weight-for-height z-score less than -3, according to WHO growth standards * For participants 6 months to 5 years of age: mid-upper arm circumference (MUAC) less than 115 mm * For participants older than 5 years of age: BMI z-score less than -3, according to WHO growth standards Note: Children who are stunted may be enrolled. * HIV status determined based on testing methods meeting the requirements specified in protocol * For participants living with HIV, has been taking a stable ARV regimen for at least two consecutive weeks at entry, as determined by the site investigator based on participant and parent/guardian report and available medical records Note: Dose and formulation changes (e.g., for growth) within the two weeks prior to entry are permitted. See below for exclusionary ARVs. * For participants who have reached menarche or who are engaging in sexual activity (self-reported): not pregnant based on testing performed within 5 days prior to entry during the study screening period (i.e., within 28 days prior to entry) * For participants who are engaging in sexual activity (self-reported): agrees to use at least one effective, medically accepted birth control method while on study, based on participant and parent/guardian report at entry * Expected to be available for two weeks of study participation, based on participant and parent/guardian report at entry Exclusion Criteria: * Has tuberculosis meningitis Stage 2 or 3, as determined by the site investigator based on medical records * Receipt of any of the following, within 14 days prior to entry, as determined by the site investigator based on participant/parent/guardian report and available medical records * Rifamycins * Any prohibited medication (see protocol for listing) * For participants living with HIV: ritonavir-boosted protease inhibitors (e.g., ritonavir-boosted lopinavir, ritonavir-boosted darunavir), atazanavir, nevirapine etravirine, efavirenz, or cobicistat * Receipt of any investigational agent or device within 28 days prior to entry, as determined by the site investigator based on participant/parent/guardian report and available medical records Note: Co-enrollment in COVID-19 vaccine studies and receipt of a COVID-19 vaccine under emergency use authorization (or local equivalent) is allowed, with prior approval from the CMC.
