Brief Summary:
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).

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Saquinavir Drug: Zalcitabine Phase 2

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.)

Study Type : Interventional  (Clinical Trial)
Enrollment : 900 participants
Masking: Double
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Multicenter, Parallel Study of Ro 31-8959 (Saquinavir; HIV Proteinase Inhibitor) Alone, HIVID (Dideoxycytidine; Zalcitabine, ddC) Alone, and Both in Combination, as Treatment for Advanced HIV Infection (CD4 50-300 Cells/mm3) in Patients Discontinuing or Unable to Take Retrovir (Zidovudine; AZT) Therapy
