The Safety and Effectiveness of Clarithromycin Plus Ethambutol Used With or Without Clofazimine in the Treatment of MAC in Patients With AIDS
A Randomized Open-Label Study of the Tolerability and Efficacy of Clarithromycin and Ethambutol in Combination With or Without Clofazimine for the Treatment of Disseminated MAC (dMAC) in Patients With AIDS

SECONDARY: To determine the proportion of patients achieving a sterile blood culture along with the time required to achieve it. To determine the duration of bacteriological response, defined as length of time that blood cultures remain sterile.
