Safety and Tolerability Study to Evaluate Lower Dose of GSK2248761 in Antiretroviral Treatment-Naive HIV-1 Infected Adults.

Summary

GSK has in-licensed a novel NNRTI-class candidate (GSK2248761, IDX12899) for the treatment of subjects with HIV-1 infection from Idenix Pharmaceuticals. Idenix Pharmaceuticals completed a proof-of-concept study evaluating GSK2248761 monotherapy over seven days in forty treatment-naïve subjects infected with HIV-1. GSK2248761 doses sequentially evaluated were 800 mg QD, 400 mg QD, 200 mg QD and 100mg QD. This study will evaluate a lower dose, or doses, of GSK2248761 to better characterize the dose-response and concentration-response curves. The results from this study will be used to select doses for future clinical studies in HIV-1 infected subjects.
