Secondary

MeasureTime frameDescription
Stage 1 and Stage 2: Change From Baseline in Lipoarabinomannan (LAM) in the Mycobacteria Growth Indicator Tube® (MGIT) SystemBaseline to Day 14LAM is a key component of the M. tuberculosis cell wall and the decline of sputum LAM concentrations has been shown to correlate closely with CFU decreases in sputum counted on agar media during the first 14 days of TB treatment. Sputum LAM concentration at each collection time point was measured using MGIT system. Baseline LAM was calculated as the log 10 of the average from Day -2 and Day -1 and the change from baseline in log10 was calculated as post-baseline minus baseline for each parameter.
Stage 1 and Stage 2: Change From Baseline in Time to Detection (TTD) in the MGIT SystemDay 1 to Day 14 of treatment period + 42 days of inoculation period (up to 56 days)TTD is the time from start of inoculation of a sputum sample until a MGIT machine detects a positive signal during the 42-day incubation period. One TTD measurement, reported in days and hours was taken at each of the visits at Days -2, -1, 2, 4, 6, 8, 10, 12 and 14. TTD values were then calculated as days + hours/24 to be used in deriving the analysis values of TTD. Each sample collected from Day -2 to Day 14 were inoculated for 42 days. Baseline TTD was derived using Day -2 and Day -1 MGIT culture with a pure positive result for Mycobacterium tuberculosis. Postbaseline TTD analysis values from Day 1 were derived based on the MGIT culture result as follows: If MGIT culture result was negative for MTB complex, TTD was set to 42 days; If the MGIT culture was pure positive for MTB, but the TTD took longer than 42 days, TTD was capped at 42 days.
Stage 2: Change From Baseline in TB Bacterial Load in Sputum as a Measure of EBABaseline to Day 14Bacterial load in sputum at each collection time point was measured by CFU counts on agar media culture. EBA was determined by the rate of decline per day in log10CFU/mL during the first 14 days of treatment. Change from baseline in log 10 CFU was calculated as post-baseline minus baseline. A larger EBA in positive direction indicates a better drug effect.

Stage 1: A total of 76 participants were randomized in 4 cohorts to receive either OPC-167832 10 milligrams (mg), 30 mg, 90 mg & 3 mg or a combination of rifampicin, isoniazid, ethambutol, and pyrazinamide (RHEZ). Stage 2: A total of 46 participants were randomized in 4 groups to receive OPC-167832+delamanid, OPC-167832+bedaquilline (BDQ), OPC-167832+delamanid+BDQ or RHEZ.

An AE is defined as any untoward medical occurrence in a clinical trial participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. TEAEs were all AEs which started after the start of randomized study drug treatment or if the event was continuous from baseline and was serious, study drug-related, or resulted in death, discontinuation, interruption, or reduction of study therapy.

Time frame: From first dose of study drug to end of follow up period (up to 34 days)

Stage 1 and Stage 2: Terminal-phase Elimination Half-life (t1/2,z) of OPC-167832 When Administered Alone (Stage 1) and in Combination With Delamanid, and BDQ (Stage 2)

T1/2,z is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose. Half-life (T1/2) is determined in the terminal phase after drug administration, which is calculated from the relationship T1/2 = ln2/λz where λz is the terminal-phase slope obtainable from non-compartmental analysis (NCA). The values reported for this outcome measure (OM) are estimates and not actual observed data.

Stage 1: Change From Baseline in TB Bacterial Load in Sputum as a Measure of Early Bactericidal Activity (EBA)

Bacterial load in sputum at each collection time point was measured by CFU counts on agar media culture. EBA was determined by the rate of decline per day in log10CFU/mL during the first 14 days of treatment. Change from baseline in log 10 CFU was calculated as post-baseline minus baseline. A larger EBA in positive direction indicates a better drug effect.

Time frame: Baseline to Day 14

Population: MITT Analysis Set included randomized participants who were agar media culture positive at baseline (either at Day -2 or at Day -1, or both), received any dose of IMP, and had at least one post-baseline CFU count value. Overall number analyzed is the number of participants with data available for analysis.

Stage 1 and Stage 2: Change From Baseline in Lipoarabinomannan (LAM) in the Mycobacteria Growth Indicator Tube® (MGIT) System

LAM is a key component of the M. tuberculosis cell wall and the decline of sputum LAM concentrations has been shown to correlate closely with CFU decreases in sputum counted on agar media during the first 14 days of TB treatment. Sputum LAM concentration at each collection time point was measured using MGIT system. Baseline LAM was calculated as the log 10 of the average from Day -2 and Day -1 and the change from baseline in log10 was calculated as post-baseline minus baseline for each parameter.

Time frame: Baseline to Day 14

Population: MITT Analysis Set included randomized participants who were agar media culture positive at baseline (either at Day -2 or at Day -1, or both), received any dose of IMP, and had at least one post-baseline CFU count value. Overall number of participants analyzed is the number of participants with data available for analysis. As pre-specified in the protocol and SAP, for Stage 2 data for participants in RHEZ arm was not included in this analysis.

Stage 1 and Stage 2: Change From Baseline in Time to Detection (TTD) in the MGIT System

TTD is the time from start of inoculation of a sputum sample until a MGIT machine detects a positive signal during the 42-day incubation period. One TTD measurement, reported in days and hours was taken at each of the visits at Days -2, -1, 2, 4, 6, 8, 10, 12 and 14. TTD values were then calculated as days + hours/24 to be used in deriving the analysis values of TTD. Each sample collected from Day -2 to Day 14 were inoculated for 42 days. Baseline TTD was derived using Day -2 and Day -1 MGIT culture with a pure positive result for Mycobacterium tuberculosis. Postbaseline TTD analysis values from Day 1 were derived based on the MGIT culture result as follows: If MGIT culture result was negative for MTB complex, TTD was set to 42 days; If the MGIT culture was pure positive for MTB, but the TTD took longer than 42 days, TTD was capped at 42 days.

Time frame: Day 1 to Day 14 of treatment period + 42 days of inoculation period (up to 56 days)

Population: MITT Analysis Set included randomized participants who were agar media culture positive at baseline (either at Day -2 or at Day -1, or both), received any dose of IMP, and had at least one post-baseline CFU count value.

Stage 2: Change From Baseline in TB Bacterial Load in Sputum as a Measure of EBA

Bacterial load in sputum at each collection time point was measured by CFU counts on agar media culture. EBA was determined by the rate of decline per day in log10CFU/mL during the first 14 days of treatment. Change from baseline in log 10 CFU was calculated as post-baseline minus baseline. A larger EBA in positive direction indicates a better drug effect.

Time frame: Baseline to Day 14

Population: MITT Analysis Set included randomized participants who were agar media culture positive at baseline (either at Day -2 or at Day -1, or both), received any dose of IMP, and had at least one post-baseline CFU count value. Overall number analyzed is the number of participants with data available for analysis.

T1/2,z is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose. Half-life (T1/2) was determined in the terminal phase after drug administration, which was calculated from the relationship T1/2 = ln2/λz where λz is the terminal-phase slope obtainable using the NCA method. The values reported for this OM are estimates and not actual observed data. Hence, the value might not lie within the sampling timepoints provided in the timeframe.
