Purpose

Primary objective: To compare the pharmacokinetics of rifapentine and 25-desacetyl rifapentine at three different doses: 600 mg, 900 mg, and 1200 mg.

Secondary objective: To describe any correlation between pharmacokinetic parameters of three different doses of rifapentine plus a standard dose of isoniazid and the occurrence of toxicity attributed to anti-tuberculosis treatment.

Estimated Enrollment:	36
Study Start Date:	March 2000
Estimated Study Completion Date:	May 2001

Detailed Description:

We will enroll 24-36 patients, 8-12 at each dose of 600, 900 and 1200 mg rifapentine Admissions for pharmacokinetic studies will take place during the continuation phase of tuberculosis therapy. Patients participating in a double-blinded trial of the tolerability and safety of higher doses of rifapentine during continuation phase therapy and consenting to participate in the pharmacokinetic study may be admitted to a Clinical Research Center (CRC) to allow for frequent blood sampling over a 24-hour period. Otherwise, patients will be evaluated in the clinic.
