Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind Multicenter Trial to Compare the Safety and Efficacy of Lamivudine (3TC; GR109714X) Monotherapy Versus Zidovudine (AZT) Monotherapy Versus 3TC Administered With AZT in the Treatment of HIV-1 Infected Patients Who Are AZT Naive (< 4 Weeks) With CD4 Cell Counts of 200-500 Cells/mm3

Further study details as provided by NIH AIDS Clinical Trials Information Service:

Enrollment: 320

Detailed Description:

Patients are randomized to one of four treatment arms: 3TC alone, AZT alone, low-dose 3TC plus AZT, or high-dose 3TC plus AZT. Patients receive treatment 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.
