To compare the safety, tolerance, and efficacy of saquinavir mesylate (Ro 31-8959) alone, zalcitabine (dideoxycytidine; ddC) alone, and both in combination, in patients discontinuing or unable to take zidovudine (AZT).

Estimated Enrollment: 900
Detailed Description:
Patients are randomized to one of three treatment regimens: ddC alone, Ro 31-8959 alone, and ddC plus Ro 31-8959. Treatment continues for at least 48 weeks. Patients are stratified by baseline CD4 count. (Per 09/26/94 amendment, a fourth arm, lower dose Ro 31-8959 plus ddC, was discontinued.)

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
