SETTING:
Twenty tuberculosis (TB) clinics in the United States and Canada. 
OBJECTIVE:
To evaluate the efficacy and safety of a 6-month intermittent
regimen of rifampin (RMP), pyrazinamide (PZA) and ethambutol (EMB) in human immunodeficiency virus (HIV) negative patients with culture-confirmed pulmonary or extra-pulmonary tuberculosis and either isoniazid (INH) resistance or INH intolerance. 
DESIGN:
Patients were enrolled in a single-arm clinical trial to receive intermittent dosing after at least 14 initial daily doses of RMP+PZA+EMB. Treatment was continued twice (BIW) or thrice weekly (TIW) per physician/patient preference for a total of 6 months, with 2 years of follow-up for
relapse after treatment. 
RESULTS:
From 1999 to 2004, 98 patients were enrolled, 78 with reported INH resistance and 20 with INH intolerance. BIW dosing was used in 77 and TIW in 21. Study treatment was completed
in 73 (74%). Reasons for discontinuation were hepatic adverse events (n= 12), other adverse effects (n= 3) and other reasons (n= 10). Failure (n= 1) and relapse (n= 2) occurred in 3 (3.5%, 95%CI 1.29.8) of 86
patients eligible for efficacy analysis, all occurring in patients with cavitary, acid-fast bacilli smear-positive pulmonary TB. 
CONCLUSIONS:
Intermittent RMP+PZA+EMB appears to be effective in HIV-negative patients,
but the regimen is poorly tolerated, possibly due to the prolonged use of PZA. Alternative regimens of lower toxicity are needed.",
