Inclusion Criteria

Subjects must meet all of the following inclusion criteria to be eligible for participation in this study:

•The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures.
•Plasma HIV 1 RNA levels = 2,500 copies/mL at screening
•No prior use of any approved or experimental anti-HIV drug for any length of time.
•Screening genotype report showing sensitivity to EFV, FTC, TDF, and lack of the RPV mutations K101E/P, E138A/G/K/Q/R, Y181C/I/V, and H221Y
•Normal ECG (or if abnormal, determined by the Investigator to be not clinically significant)
•Hepatic transaminases (AST and ALT) = 5 x upper limit of normal (ULN)
•Total bilirubin = 1.5 mg/dL
•Adequate hematologic function (absolute neutrophil count = 750/mm3; platelets = 50,000/mm3; hemoglobin = 8.5 g/dL)
•Serum amylase = 5 x ULN (subjects with serum amylase > 5 x ULN will remain eligible if serum lipase is = 5 x ULN)
•Adequate renal function:
Estimated glomerular filtration rate = 50 mL/min according to the Cockcroft Gault formula:
Male: ((140 – age in years) x (wt in kg))/ (72 x (serum creatinine in mg/dL)) = CLcr (mL/min)
Female: ((140 – age in years) x (wt in kg))/ (72 x (serum creatinine in mg/dL)) x 0.85 = CLcr (mL/min)
•Females of childbearing potential (as defined in Section 7.8.1) must agree to utilize protocol-recommended methods of contraception (as defined in section 7.8.1), or be non-heterosexually active, practice sexual abstinence or have a vasectomized partner) from screening throughout the duration of study period and for 12 weeks following the last dose of study drug.

Female subjects who utilize hormonal contraceptive as one of their birth control methods must have used the same method for at least three months prior to study dosing

Female subjects who have stopped menstruating for < 12 months, or serum follicle stimulating hormone level is not within the post-menopausal range must agree to utilize protocol-recommended methods of contraception

•Male subjects must agree to utilize protocol-recommended methods of contraception (as defined in section 7.8.2),during heterosexual intercourse from the screening visit, throughout the duration of the study and for 12 weeks following discontinuation of investigational medicinal product or be non-heterosexually active, practice sexual abstinence. or be vasectomized.

Exclusion Criteria

Subjects who meet any of the following exclusion criteria are not to be enrolled in (or may be discontinued from) this study:
