About

The purpose of this study is to compare GW433908 and nelfinavir when each is given with abacavir and lamivudine to HIV patients who have not taken antiretroviral drugs.

Full description

Patients are randomized in a 2:1 scheme to 1 of 2 treatment groups. Group 1 receives GW433908 plus abacavir (ABC) plus lamivudine (3TC); Group 2 receives nelfinavir (NFV) plus ABC plus 3TC. Patients undergo safety and efficacy assessments at the Screening Visit, Day 1 (Entry), and Weeks 1, 2, 4, 8, 12, 16, 20, 24, and every 8 weeks thereafter. A follow-up visit is performed 4 weeks after the permanent discontinuation of study drug. Detailed assessments for the development of lipodystrophy/fat redistribution occur at Day 1, Week 24, Week 48, and every 16 weeks thereafter. Patients have examinations and laboratory tests performed at visits.
