Outcome Measures
Primary Outcomes (1)
Rate of Change in Time to Sputum Culture Positivity (TTP) Over 8 Weeks in the Mycobacterial Growth Indicator Tube (MGIT) System
The bactericidal activity (BA) was determined by the rate of change in TTP collected from overnight sputum samples over 8 weeks of treatment in the liquid culture media MGIT system, represented by the model-fitted log(TTP) results as calculated by the regression of the observed log(TTP) results over time. The bactericidal activity of log(TTP) over Day 0 to Day 56 (BATTP\[0-56\]) was presented and expressed as the daily percentage change in TTP from Day 0 to Day 56. The mean BATTP (0-56) was calculated from Bayesian non-linear mixed effects regression models fitted to log(TTP) collected from sputum samples (observed from Day 0 to Day 56).
Day 0 to Day 56 (8 weeks)
Secondary Outcomes (1)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
First study drug administration (Day 1) up to and including the Day 70 follow-up visit (or up to and including 14 days after last study drug administration for participants not having the Day 70 follow-up visit) (70 days)

Eligibility Criteria
You may qualify if:
- Provide written, informed consent prior to all trial-related procedures. Male or female, aged between 18 and 75 years inclusive.
- Body weight (in light clothing and with no shoes) between 35 and 100 kg, inclusive.
- Tested at the trial appointed laboratory: M. Tb positive on molecular test (e.g. GeneXpert or Hain) and sputum smear-positive pulmonary TB on direct microscopy for acid-fast bacilli (at least 1+ on the IUATLD/WHO scale.
- For DS-TB treatment arms (defined as sensitive to rifampicin based on molecular sensitivity testing), Subjects should be:
- either newly diagnosed or untreated for at least 3 years after cure from a previous episode (Subject can give a history of cure and previous treatment); AND
You may not qualify if:
- For MDR-TB treatment arm (defined as resistant to rifampicin based on molecular sensitivity testing), Subjects should be:
- sensitive to moxifloxacin by molecular sensitivity testing; AND
- A chest X-ray picture which in the opinion of the Investigator is compatible with TB.
- Ability to produce an adequate volume of sputum as estimated from a screening Coached Spot Sputum Sample assessment (estimated 10 ml or more overnight production).
- Be of non-childbearing potential or using effective methods of birth control, as defined below:
- Non-childbearing potential:
- Subject - not heterosexually active or practices sexual abstinence; or
- Female Subject/sexual partner - bilateral oophorectomy, bilateral tubal ligation and/or hysterectomy or has been postmenopausal with a history of no menses for at least 12 consecutive months; or
- Male Subject/sexual partner - vasectomised or has had a bilateral orchidectomy minimally three months prior to screening.
- Effective birth control methods:
- A double contraceptive method should be used as follows:
- Double barrier method which can include any 2 of the following: a male condom, diaphragm, cervical cap, or female condom (male and female condoms should not be used together); or
- Barrier method (one of the above) combined with hormone-based contraceptives or an intra-uterine device for the female Subject/partner; and are willing to continue practicing birth control methods throughout treatment and for 6 months (both male and female Subjects) after the last dose of study medication or discontinuation from study medication in case of premature discontinuation.
- (Note: Hormone-based contraception alone may not be reliable when taking IMP; therefore, hormone-based contraceptives alone cannot be used by female Subjects or female partners of male Subjects to prevent pregnancy).
