ListOutcomeTime frameDescription
Primary
Cumulative Rate of Culture-Confirmed TB Disease in Participants ≥18 Years of Age AND Culture-Confirmed or Probable (Clinical) TB Disease in Participants Less Than [<]18 Years of Age at 33 Months After Enrollment
Baseline up to Month 33
Cumulative TB disease rate defined as number of participants ≥18 years old with culture-confirmed TB disease (defined as positive culture for Mycobacterium tuberculosis \[MTB\]) and those \<18 years old with probable (clinical) TB disease (defined as objective evidence of clinical TB disease \[cough, fever, night sweats, weight loss, or hemoptysis\] based on history or physical exam plus radiograph, computed tomography \[CT\] scan, other diagnostic tests PLUS response to antituberculosis therapy AND objective improvement of radiograph or other diagnostic tests; OR evidence of granuloma with organism positive for acid-fast bacilli \[AFB\], or caseating granulomata at autopsy or biopsy) between enrollment and the 990th Day of the Trial (33 months after enrollment, or end of the trial) per 100 participants with (w/)33 months of follow-up calculated using survival analysis methods (Kaplan-Meier approach).
Secondary
Cumulative Rate of Culture-Confirmed TB Disease in Participants ≥18 Years of Age AND Culture-Confirmed or Probable (Clinical) TB Disease in Participants <18 Years of Age at 24 Months Following Completion of Study Therapy
Baseline up to Month 27 (3RPT/INH) or Month 33 (9INH)
Cumulative TB disease rate was defined as number of participants ≥18 years old with culture-confirmed TB disease (defined as positive culture for MTB) and those \<18 years old with probable (clinical) TB disease (defined as objective evidence of clinical TB disease \[cough, fever, night sweats, weight loss, or hemoptysis\] based on history or physical exam plus radiograph, CT scan, other diagnostic tests PLUS response to antituberculosis therapy AND objective improvement of radiograph or other diagnostic tests; OR evidence of granuloma with organism positive for AFB\], or caseating granulomata at autopsy or biopsy) between enrollment and 24 months after completion of study therapy per 100 participants with up to 33 months of follow-up and was calculated using survival analysis methods (Kaplan-Meier approach).
SecondaryCumulative Rate of Culture-Confirmed or Probable (Clinical) TB Disease (Regardless of Age) At 33 Months After EnrollmentBaseline up to 33 Months
Cumulative TB disease rate was defined as number of participants (regardless of age) with culture-confirmed TB disease (defined as positive culture for MTB\]) or probable (clinical) TB disease (defined as objective evidence of clinical TB disease \[cough, fever, night sweats, weight loss, or hemoptysis\] based on history or physical exam plus radiograph, CT scan, other diagnostic tests PLUS response to antituberculosis therapy AND objective improvement of radiograph or other diagnostic tests; OR evidence of granuloma with organism positive for AFB, or caseating granulomata at autopsy or biopsy) between enrollment and the 990th Day of the Trial (33 months after enrollment, or end of the trial) per 100 participants w/33 months of follow-up and was calculated using survival analysis methods (Kaplan-Meier approach).
SecondaryPercentage of Participants With Drug Discontinuation Due to Adverse Drug Reactions Associated With 3RPT/INH or 9INHBaseline up to 60 days after the last dose of study drug (Month 5 [3RPT/INH] or Month 11 [9INH])
Discontinuation of study drug due to an adverse drug reaction associated with either 3RPT/INH or 9INH was defined as discontinuing treatment and/or study due to a treatment-related adverse event (AE) (considered either possibly, probably, or definitely related to the study drug by the investigator).
SecondaryPercentage of Patients With Grade 3 or 4 Drug Toxicities Associated With 3RPT/INH or 9INHBaseline up to 60 days after the last dose of study drug (Month 5 [3RPT/INH] or Month 11 [9INH])
Drug toxicities (or AEs) were graded using Common Toxicity Criteria (CTC version 2.0, Publish Date April 30, 1999, Cancer Therapy Evaluation Program). Grade 3 and 4 drug toxicities associated with 3RPT/INH or 9INH were defined as treatment-related Grade 3 or 4 AEs (considered either possibly, probably, or definitely related to the study drug by the investigator).
SecondaryPercentage of Participants With Death Due to Any CauseBaseline up to Month 35
SecondaryPercentage of Participants With Methadone Withdrawal Associated With 3RPT/INH and 9INH Among Participants Receiving Concomitant MethadoneBaseline to Month 33
Among participants concomitantly receiving methadone, the development of methadone withdrawal (defined as having \>3 new symptoms for \>7 days: nausea and vomiting, abdominal cramps, body aches, restlessness, irritability, dilated pupils, tremors, involuntary twitching, lacrimation, rhinorrhea, sneezing, yawning, excessive perspiration, goose flesh, or diarrhea).
SecondaryPercentage of Participants With Drug Discontinuation for Any Reason Associated With 3RPT/INH or 9INHBaseline up to Month 3 (3RPT/INH) or Month 9 (9INH)Drug discontinuations for any reason associated with 3RPT/INH or 9INH included all reasons for discontinuation from study treatment, regardless of relationship to treatment.
SecondaryPercentage of Participants Who Completed the Treatment RegimenBaseline up to Month 3 (3RPT/INH) or Month 9 (9INH)
Completion in the 3RPT/INH arm was defined as: received 12 doses of RPT/INH within 16 weeks (12 weeks optimal). However, participants were considered to have completed therapy if at least 11 doses of RPT/INH had been received (\~90%) during the 16-week time period. Completion in the 9INH arm was defined as: received 270 doses of INH within 52 weeks (39 weeks optimal). However, participants were considered to have completed therapy if at least 240 doses of INH were received (\~90%) during the 52-week period.
Secondary
Cumulative Rate of Culture-Confirmed TB Disease in Participants ≥18 Years of Age AND Culture Confirmed or Probable (Clinical) TB Disease Among Participants <18 Years of Age Who Completed Study Phase Therapy Within 33 Months of Enrollment
Baseline up to Month 33
Cumulative TB disease rate was defined as number of participants ≥18 years old with culture-confirmed TB disease (defined as positive culture for MTB) and \<18 years old with probable (clinical) TB disease (defined as objective evidence of clinical TB disease \[cough, fever, night sweats, weight loss, or hemoptysis\] based on history or physical exam plus radiograph, CT scan, other diagnostic tests PLUS response to antituberculosis therapy AND objective improvement of radiograph or other diagnostic tests; OR evidence of granuloma with organism positive for AFB\], or caseating granulomata at autopsy or biopsy) between enrollment and 33 months after enrollment (for those who completed therapy within 33 months) per 100 participants w/33 months of follow-up and was calculated using survival analysis methods (Kaplan-Meier approach).
