Brief Summary:
This study tests a new form of didanosine, ddI EC, a coated pill that passes through the stomach before dissolving. The purpose of this study is to compare the effectiveness of an anti-HIV drug combination that includes ddI EC versus another anti-HIV drug combination.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Lamivudine/Zidovudine Drug: Nelfinavir mesylate Drug: Stavudine Drug: Didanosine Phase 3

Detailed Description:
Patients are randomized to 1 of 2 groups for 48 weeks of open-label treatment. Group 1 receives ddI EC plus d4T plus NFV. Group 2 receives Combivir plus NFV. Antiviral activity is determined by the proportion of patients with HIV RNA levels of less than 400 copies/ml at Week 48.
