Percentage of Participants With DS-TB Reporting ≥ Grade 3 Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs
大体时间:Two weeks after the end of treatment [19 weeks for Arm 1 (DBOS) and Arm 2 (PBOS), and 28 weeks for Arm 3 (HRZE)]
|
An Adverse Event is any untoward medical occurrence in a patient or clinical trial participant, temporally associated with the use of trial intervention, whether or not it is considered related to trial intervention.
TEAEs are new or worsening AEs that occur on or after first dose of treatment and no later than two weeks after last dose of treatment.
Intensity for each TEAE was graded using Division of Allergy and Infectious Diseases (DAIDS) grading as Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Potentially Life-threatening), or Grade 5 (Death), as determined by Investigator.
A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose that resulted in death, was immediately life-threatening, required inpatient hospitalization or prolongation of an existing hospitalization, significant disability or incapacity, had a congenital anomaly or birth defect, or was determined to be a medically significant or important event or reaction.

Percentage of Participants With Sputum Culture Conversion (SCC) in Mycobacteria Growth Indicator Tube (MGIT) Culture
大体时间:Week 9, Week 15, and Week 19 for DBOS/PBOS or Week 28 for HRZE
|
Sputum culture conversion (SCC) was assessed using MGIT liquid culture and was defined as two successive Mtb culture negative results collected at least 5 days apart up to and including the assessment timepoint (Week 28) without any intervening or subsequent Mtb culture positive results through Week 28, ignoring contaminated and unevaluable cultures.
A higher percentage reflects more participants achieving and maintaining sputum culture conversion to negative for Mtb.

Week 9, Week 15, and Week 19 for DBOS/PBOS or Week 28 for HRZE
|
|
Median Time to Sustained SCC to Negative for Mtb Growth in MGIT
大体时间:Through Month 12 post-randomization
|
Time to sustained SCC (SSCC) is defined as the time from first dose to the first of two successive Mtb culture negative results, collected at least 5 days apart, without any intervening or subsequent Mtb culture positive result for the duration of a participant's follow-up.
For positive Mtb culture results at or after Week 17, the strain must have been indistinguishable from baseline based on whole genome sequencing results to lose SSCC status.
Participants in the who never achieved SSCC were censored at the date of sputum collection that yielded their last negative or positive culture result
|
Through Month 12 post-randomization
|
|
Change From Baseline in Sputum MGIT Culture Time to Detection (TTD)
大体时间:Baseline (Day 1) and at Weeks 4, 9, 13, and 17
|
TTD is measured as the length of time in days from the beginning of culture incubation to the detection of pure Mtb growth.
At each study visit, up to two MGIT sputum cultures were performed.
The shorter TTD value from the (up to) two cultures resulted as pure Mtb-positive without contamination, was used for analysis at that timepoint.
If culture was negative for Mtb, TTD was set to 43 days.
Culture results of "Positive for MTB Complex with contamination", "Positive for MTB and NTM", "Contaminated", or "No result", were excluded from the analysis.
Mean change from Baseline in sputum MGIT culture TTD was calculated as change in the TTD at week T minus baseline TTD.
Higher TTD indicates slower bacterial growth.

Percentage of Participants Developing Resistance Against Each Drug
大体时间:Up to 12 months post-randomization
|
Phenotypic drug susceptibility testing (DST) was performed on Mtb-positive cultures in the MGIT system to assess if any resistance had developed during and after treatment.
DST was performed on the baseline visit or Week 1 sputum culture depending on suitability of culture growth for DST performance, and again on the first culture positive for Mtb at Week 13 or afterwards in all arms.
WHO-recommended critical concentrations were used to test for susceptibility to Bedaquiline (1.0 microgram [ug]/mL), Delamanid (0.6 ug/mL), Isoniazid (0.1 ug/mL), Rifampicin (1.0 ug/mL), Pyrazinamide (100 ug/mL), and Ethambutol (5 ug/mL).

Median Minimum Inhibitory Concentration (MIC) Values at Baseline and Post-Baseline for Delamanid, Pretomanid, Bedaquiline, OPC-167832, and Sutezolid
大体时间:Up to 12 months post-randomization
|
MIC testing determined the lowest drug concentration for Mtb susceptibility in the DBOS and PBOS groups, following the same schedule as DST.
Bedaquiline, Delamanid, and Pretomanid were tested via the MGIT system, while OPC-167832 and Sutezolid used EUCAST-recommended broth microdilution.
Baseline is defined as last assessment made prior to first administered dose of trial medication.
In measured values table below, baseline and post-baseline median MIC values are presented for each drug.
