Raltegravir Therapy for Women With HIV and Fat Accumulation

Summary

Ritonavir-boosted protease inhibitor (PI) regimens have become a backbone for treatment of people with HIV. However, adverse drug effects, particularly lipodystrophy/lipoatrophy are closely associated with these regimens. Therefore, there is a need for a drug with comparable effectiveness to the ritonavir boosted PIs without the side effects of dyslipidemia, which has been associated with elevated cholesterol and cardiovascular disease Raltegravir is an HIV integrase inhibitor in phase III clinical development. To date there are no approved drugs that target the same stage of the HIV-1 lifecycle. However, data from studies indicate that raltegravir is generally safe and well tolerated and has strong antiretroviral activity when used in combination with licensed antiretroviral medications. This study aims to demonstrate that patients substituting raltegravir for a PI or NNRTI based antiretroviral regimen will be associated with a 10% reduction in body fat over 24 weeks. The study will consist of a total of 10 subject visits over a period of 48 weeks. Approximately 40 female patients will participate in this study (approximately 10 at UCLA).
