Outcome Measures
Primary Outcomes (1)
Time To Sputum Culture Conversion (SCC) During 6-Month Intensive Period Using The Mycobacteria Growth Indicator Tube (MGIT) System
SCC at 6 months was determined by the observation of a sputum specimen negative for growth of mycobacterium tuberculosis (MTB) using the MGIT culture system, followed by at least 1 confirmatory negative sputum culture at least 25 days after the first negative and not followed by a confirmed positive (defined as at least 2 observed positive results, not taking into account indeterminate, missing, or contaminated results). 2 specimens were collected at each visit and an algorithm in the statistical analysis plan (SAP) was used to define a single representative result. Time to SCC was then defined as the interval between the date of first dose of IMP and the date of first of 2 consecutive negative single representative time points that were at least 25 days apart. The median time in days to SCC up to Month 6 is presented.

Study Arms (2)
Delamanid + OBR
EXPERIMENTALIn the first period of this study, known as the 6-month Intensive Period, participants were randomized to receive 100 mg delamanid orally BID (morning and evening) + OBR for 2 months, followed by 200 mg delamanid QD (every morning) + OBR for 4 months. Following the 6-month Intensive Period, participants entered the second period of the study, known as the Continuation Period, wherein OBR was administered alone for 12 to 18 months. OBR given throughout the study was administered as per WHO guidelines and national treatment norms.
Placebo + OBR
PLACEBO COMPARATORIn the first period of this study, known as the 6-month Intensive Period, participants were randomized to receive placebo orally BID (morning and evening) + OBR for 2 months followed by placebo QD (every morning) + OBR for 4 months. Following the 6-month Intensive Period, participants entered the second period of the study, known as the Continuation Period, wherein OBR was administered alone for 12 to 18 months. OBR given throughout the study was administered as per WHO guidelines and national treatment norms.
Interventions
The assigned doses of delamanid were administered with an OBR. The selection and administration of the OBR were based on WHO's guidelines for the programmatic management of drug-resistant TB, in conjunction with national TB program guidelines in each country.
Matching placebo was administered with an OBR. The selection and administration of the OBR were based on WHO's guidelines for the programmatic management of drug-resistant TB, in conjunction with national TB program guidelines in each country.

Limitations and Caveats
The primary endpoint was established at 6 months. Treatment, intensive data collection, and statistical power calculations focused on the first 6 months. Given the unexpected placebo + OBR response, cautiously interpret 18, 24, and 30 month outcomes.
