Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Randomized Lamivudine (3TC)/Dideoxycytidine (ddC) Double-Blind Multicenter Trial (With Open-Label AZT) to Evaluate the Safety and Efficacy of Low Dose 3TC Administered Concurrently With AZT Versus High Dose 3TC Administered Concurrently With AZT Versus ddC Administered Concurrently With AZT in the Treatment of HIV-1 Infected, AZT-Experienced (>= 24 Weeks) Patients With CD4 Counts of 100-300 Cells/mm3
