Brief Summary:

PRIMARY: To assess the tolerability of the combination regimen of clarithromycin plus ethambutol with or without clofazimine in patients with disseminated Mycobacterium avium Complex (dMAC).

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.
