Inclusion Criteria

•Newly diagnosed culture and/or Xpert/MTB Ultra positive pulmonary TB
•Rifampicin mono-resistance detected using the results from two susceptibility-testing assays (GeneXpert, HainMTBDRplus or phenotypic DST). This will be done on a sputum sample during screening, or with pre-existing results available from the local health care service.
•Provide written informed consent prior to all trial-related procedures
•Male or female aged 18 years and older.
•Patients on TB treatment for less then 8 days.

•Currently on MDR-TB treatment for more than 2 weeks.
•Any participant with a clinically significant medical condition that, in the opinion of the investigator, may be negatively affected by the patient’s participation in the study.
•Any subject with a Karnofsky score < 50.
•Having participated in other clinical studies within 8 weeks prior to trial start where investigational agents were used that may potentially impact current trial outcome.
•Participant who is pregnant, breast-feeding (and not willing to stop), or planning to conceive a child within 6 months of cessation of treatment.
