Tolerance, Safety, and Activity of Rifapentine Alone and in Combination Therapy in AIDS Patients With Mycobacterium Avium Complex Bacteremia.

June 23, 2005 updated by: Anderson Clinical Research
To determine the antimicrobial activity and tolerability of rifapentine alone and in combination therapy in patients with AIDS and disseminated Mycobacterium avium complex (MAC) bacteremia. To determine the pharmacokinetics of rifapentine and its metabolite, 25-desacetyl, alone and in combination therapy. To determine the pharmacokinetics of azithromycin and clarithromycin (and its 14-OH metabolite) in combination therapy.

Detailed Description

This open-label, sequential study is conducted in two parts: a monotherapy phase and a combination treatment phase.

In the monotherapy phase sequential 3-patient cohorts receive 1 of 3 doses of rifapentine monotherapy.

In the combination treatment phase, 12 patients each are randomized to one of three arms:

Arm I: Rifapentine (assigned dose level based on monotherapy phase) plus azithromycin.

Arm II: Rifapentine (assigned dose level) plus clarithromycin. Arm III: Rifapentine (assigned dose level) plus ethambutol.
