Brief Summary:

To evaluate the safety and efficacy of low and high doses of lamivudine ( 3TC ) in combination with zidovudine ( AZT ) and zalcitabine ( dideoxycytidine; ddC ) in combination with AZT.

PER 02/27/95 AMENDMENT: To evaluate the efficacy and safety of both blinded and open-label combination therapy.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Lamivudine Drug: Zidovudine Drug: Zalcitabine Phase 3

Detailed Description:

Patients are randomized to one of three treatment arms: low-dose 3TC plus AZT, high-dose 3TC plus AZT, or ddC plus AZT. Treatment continues for 32 weeks, with possible extension to 52 weeks.

PER 02/27/95 AMENDMENT: Patients may continue therapy on AZT and low-dose 3TC on an open-label basis. Open-label therapy continues with follow-up every 8 weeks until intolerable toxicity occurs or study terminates.

Study Type : Interventional  (Clinical Trial)
Enrollment : 325 participants
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
