About
The primary objective of this study is to evaluate the efficacy of 400 mg QD nevirapine extended release (NVP XR) formulation versus 200 mg BID nevirapine immediate release (NVP IR) in ARV therapy naïve HIV-1 infected patients after 48 weeks of treatment. Secondary objectives are to evaluate safety and pharmacokinetics of NVP XR and NVP IR.

Adequate renal function defined as a calculated creatinine clearance (CLCr) greater than or equal to 50 mL/min according to the Cockcroft-Gault formula as follows:
Male: (140 - age in years) x (weight in kg) divided by 72 x (serum creatinine in mg/dl) = CLCr (mL/min).
Female: (140 - age in years) x (weight in kg) divided by 72 x (serum creatinine in mg/dl) x 0.85 = CLCr (mL/min).
Karnofsky score >70 (see Appendix 10.4)
An HIV-1 viral load of 1,000 copies/mL
Willingness to initiate CD4+ cell count-guided chemoprophylaxis to prevent important opportunistic infections as defined in Appendix 10.2
Willingness to abstain from ingesting substances which may alter plasma study drug levels by interaction with the cytochrome P450 system (listed in Appendix 10.3) during the study.
