Patients must have: Documented HIV infection OR documented AIDS-defining opportunistic infection or neoplasm. Previous AIDS-defining opportunistic infection, neoplasm, or condition OR CD4 lymphocyte count equal to or less than 300 cells/mm3 if symptomatic ORCD4 lymphocyte count equal to or less than 200 cells/mm3 if asymptomatic. Patients must not be currently enrolled in or must be unable to enter an AIDS Clinical Trials Group (ACTG), Community Programs for Clinical Research on AIDS (CPCRA), or other controlled clinical program because of patient ineligibility, distance from trial site, or patient refusal. Patients currently enrolled in any controlled clinical trial of an anti-HIV compound may enter this program only if they have met the end points required for termination of that trial. Patients may be co-enrolled in clinical programs of investigational compounds being tested for prophylaxis or treatment of opportunistic infections or other treatments provided that program allows ddC-AZT combination use, and concomitant administration of the other investigational drug and ddC-AZT is considered safe by the investigator.
