Comparison of Ro 31-8959 Plus Zidovudine (AZT) Versus AZT Plus Zalcitabine (ddC) Versus Ro 31-8959 Plus AZT Plus ddC

Summary

PRIMARY: To determine the efficacy and toxicity of three treatment regimens: saquinavir mesylate (Ro 31-8959) plus zidovudine (AZT) vs. AZT plus zalcitabine (dideoxycytidine; ddC) vs. Ro 31-8959 plus AZT plus ddC. SECONDARY: To investigate the pharmacokinetics and effects on various clinical parameters of the three regimens.
