Health Condition(s) or Problem(s) studied

Pulmonary tuberculosis
Infections and Infestations
Tuberculosis

Intervention(s)

Control regimen:
Two months of daily ethambutol (E), isoniazid (H), rifampicin (R), and pyrazinamide (Z) followed by four months of daily isoniazid and rifampicin (2EHRZ/4HR).

Study regimen one:
Two months of daily ethambutol, moxifloxacin (M), rifampicin, and pyrazinamide followed by two months of twice weekly moxifloxacin and rifapentine (2EMRZ/2P2M2).

Study regimen two:
Two months of daily ethambutol, moxifloxacin, rifampicin, and pyrazinamide followed by four months of once weekly moxifloxacin and rifapentine (2EMRZ/4P1M1).

Primary Outcome(s)

1. Combined rate of failure at the end of treatment and relapse, measured at 18 months
2. Presence of Rifamycin Monoresistance (RMR) in relapse cultures of HIV infected patients, measured at 5, 6, 7, 8, 9, 10, 11, 12, 15, 18 months on the four-month arm and 7, 8, 9, 10, 11, 12, 15, 18 months on the six-month arm, plus at any unscheduled visit
3. Occurrence of serious adverse events at any time during chemotherapy, recorded as they present themselves throughout the course of the trial

Added 26/10/2011: Please note, Patients will be followed up for 18 months from the commencement of chemotherapy. Follow-up visits will occur monthly until 12 months then at 15 and 18 months. However, follow-up will be stopped 12 months after the last patient has been randomised into the study; thus patients randomised in the final 6 months will have reduced follow-up.

Secondary Outcome(s)

1. Sputum culture results at two months after the initiation of chemotherapy, measured at all visits
2. Rate of completion of chemotherapy according to the protocol, measured at all visits
3. Number of observed doses of chemotherapy ingested, measured at all visits
4. Any adverse events, recorded as they present themselves throughout the course of the trial
