Cumulative Rate of Culture-Confirmed or Probable (Clinical) TB Disease (Regardless of Age) At 33 Months After Enrollment
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).
Percentage of Participants With Drug Discontinuation Due to Adverse Drug Reactions Associated With 3RPT/INH or 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).
Percentage of Patients With Grade 3 or 4 Drug Toxicities Associated With 3RPT/INH or 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).
Percentage of Participants With Death Due to Any Cause
Percentage of Participants With Methadone Withdrawal Associated With 3RPT/INH and 9INH Among Participants Receiving Concomitant Methadone
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).
Percentage of Participants With Drug Discontinuation for Any Reason Associated With 3RPT/INH or 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.
Percentage of Participants Who Completed the Treatment Regimen
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.
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
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).
Percentage of Participants With Resistance to Study Medications in Isolates of MTB From Participants Who Developed Active TB Disease Within 33 Months of Enrollment
Drug-susceptibility testing (DST) was performed on isolates of MTB obtained from participants who developed signs and symptoms of active TB disease (including sputum specimens or specimens from appropriate body site for extrapulmonary TB disease). DST was performed at site's local laboratory and sent to Sponsor for confirmatory susceptibility testing. DST included all drugs currently used to treat TB disease, including pyrazinamide (PZA) and fluoroquinolones. Susceptibility was tested for other drugs at the Sponsor laboratory at the following concentrations: INH, 0.02, 1.0, and 5.0 micrograms per milliliter (µg/mL) and rifampin (RIF), 1.0 µg/mL. Isolates resistant to RIF were assumed to be resistant to RPT.
Cumulative Rate of Culture-Confirmed or Probable TB Disease in HIV-Infected Participants Within 33 Months After Enrollment
Cumulative TB disease rate was defined as number of HIV-infected participants ≥2 years old 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).
