A Randomized Study of Daily and Intermittent Prophylactic Regimens for the Prevention of Disseminated Mycobacterium Avium Complex (MAC) and Fungal Infections in HIV-Infected Patients

June 23, 2005 updated by: Pfizer

PRIMARY: To determine the efficacy of azithromycin and rifabutin alone and in combination for the prevention of disseminated Mycobacterium avium Complex (MAC) infection in HIV-infected patients. To determine the efficacy of daily versus weekly fluconazole for the prevention of deep fungal infections in this patient population.

SECONDARY: To determine the incidence of bacterial (including mycobacterial) infections, cryptosporidiosis, and toxoplasmosis in azithromycin versus non-azithromycin containing regimens. To determine the incidence of oropharyngeal and vaginal candidiasis in patients treated with daily versus weekly fluconazole. To compare survival and outcomes of primary endpoints in the treatment arms.
