Participant Flow

The protocol design allowed enrollment of participants identified as members of the same household or group setting (such as group homes, settings) in clusters. The same treatment regimen to which a first participant was randomized could be assigned to other cluster members. All other participants enrolled were randomized individually.

Population: N equals the number of participants who developed active TB disease during the study for which DST was performed.

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.

Timeframe: Baseline up to Month 27 (3RPT/INH) or Month 33 (9INH)

Cumulative TB disease rate was defined as number of HIV-infected participants with culture-confirmed TB (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 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).
