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.
•Currently receiving antiretroviral therapy with a ritonavir-boosted PI and two NRTIs continuously for =6 months preceding the screening visit
•Have plasma HIV-1 RNA concentrations (at least two measurements) at undetectable levels (according to the local assay being used) for =6 months prior to the screening visit and have HIV RNA <50 copies/mL at the screening visit
•Be on their first or second antiretroviral drug regimen; if on their second regimen, must not have had HIV-1 RNA >50 copies/mL at the time of the change in antiretroviral drugs, nor ever experienced two consecutive HIV RNA >50 copies/mL after first achieving HIV RNA < 50 copies/mL
•No previous use of any approved or experimental non-nucleoside reverse transcriptase inhibitor (NNRTI) drug for any length of time
•Have a genotype prior to starting initial antiretroviral therapy and have no known resistance to any of the study agents at any time in the past including, but not limited to the RT resistance mutations K65R, K101E/P, E138G/K/R/Q, Y181C/I/V, M184V/I, or 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, or normal direct bilirubin
•Adequate hematologic function (absolute neutrophil count =1,000/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 =70 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) x 0.85) / (72 x (serum creatinine in mg/dL) = CLcr (mL/min)
•Females of childbearing potential (as defined in Section 7.8) must agree to utilize highly effective contraception methods (two separate forms of contraception, one of which must be an effective barrier method, or be non-heterosexually active, practice sexual abstinence or have a vasectomized partner) from screening throughout the duration of the study period and for 30 days 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 highly effective contraceptive methods
•Male subjects must agree to utilize a highly effective method of contraception during heterosexual intercourse from the screening visit, throughout the duration of the study and for 30 days following discontinuation of investigational medicinal product. A highly effective method of contraception is defined as two separate forms of contraception, one of which must be an effective barrier method, or male subjects must be non heterosexually active, practice sexual abstinence, or be vasectomized
• Age =18 years
• Life expectancy =1 year

Exclusion Criteria

Subjects who meet any of the following exclusion criteria are not to be enrolled in (or may be discontinued from) this study.
• A new AIDS defining condition diagnosed within the 30 days prior to screening (except CD4 cell count and/or percentage criteria) (refer to Appendix 5)
• Females who are breastfeeding
• Positive serum pregnancy test (female of childbearing potential)
• Proven or suspected acute hepatitis in the 30 days prior to study entry.
• Current alcohol or substance abuse judged by the Investigator to potentially interfere with subject compliance.
• A history of malignancy within the past 5 years (prior to screening) or ongoing malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or resected, non-invasive cutaneous squamous carcinoma. Subjects with cutaneous KS are eligible, but must not have received any systemic therapy for KS within 30 days of Baseline and must not be anticipated to require systemic therapy during the study.
• Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Baseline.
• Anticipated need to initiate drugs during the study that are contraindicated as indicated below, including drugs not to be used with FTC, TDF, RPV (refer to the Prescribing Information for FTC and TDF, and Investigator’s Brochure for RPV); or subjects with known allergies to the excipients of FTC/RPV/TDF FDR tablets or Truvada tablets. Also refer to the PI Prescribing Information for subjects enrolled in Treatment Arm 2.
• All investigational drugs
• Medications listed in the the following table and use of herbal/natural supplements are excluded or should be used with caution while subjects are participating in the study including those not to be taken with Viread®, Emtriva ®, Truvada®, and Rilpivirine. Refer to the current Prescribing Information for these medications for additional information.
