Inclusion Criteria

1.Subject has documented HIV-1 infection with a plasma HIV-1 RNA >=500 copies/mL at Screening. 2.Subject is ART-experienced and on stable ART for at least one month prior to Screening and through Day 1(with exceptions for ETV, EFV and NVP as detailed in Exclusion Criterion 11). 3.Subject is INI-experienced, but naïve to DTG, and either:•currently experiencing virologic failure to RAL or ELV or•experienced virologic failure while on therapy containing RAL or ELV (with documented genotypic and/or phenotypic INI resistance at time of failure) and is currently experiencing treatment failure on a subsequent regimen. 4.Subject harbours virus with :•Evidence of genotypic resistance to RAL and/or ELV on Screening resistance testing.•Evidence of phenotypic resistance to RAL on Screening resistance testing, OR•No evidence of resistance at Screening but documented historical genotypic and/or phenotypic resistance to RAL and/or ELV at time of prior INI virological failure, Phenotypic resistance is defined as the IC50 above the biological cut-off of the Phenosense assay for RAL (>1.5 FC versus wild type IC50). For ELV phenotypic resistance is defined as >2.5 FC above WT IC50. 5.Subject harbours virus with documented genotypic or phenotypic resistance to at least one drug from each of two or more of all other approved classes of ART –N(t)RTIs, NNRTIs, PIs, fusion inhibitors, co-receptor inhibitors, based on Screening genotype/phenotype and/or historical genotype/phenotype data. 6.Subject must be able to receive at least one fully active drug in the OBR (to ensure an OSS ?1) from Day 8 onwards based on the subject’s Screening Monogram resistance test Net Assessment results. 7.Subject is >=18 years of age. 8.A female is eligible to enter and participate in the study if she: a.is of non-childbearing potential defined as either post-menopausal (12 months of spontaneous amenorrhea and =45 years of age) or physically incapable of becoming pregnant with documented tubal ligation, hysterectomy or bilateral oophorectomy, or, b.is of child-bearing potential, with a negative pregnancy test at both Screen and Day 1, and agrees to use one of the methods of contraception listed below to avoid pregnancy: •Complete abstinence from intercourse from 2 weeks prior to administration of the investigational products, throughout the study, and for at least 2 weeks after discontinuation of all study medications, •Double barrier method (male condom/spermicide, male condom/diaphragm, diaphragm/spermicide), •Approved hormonal contraception may be administered with DTG (see the SPM for a listing of examples of approved hormonal contraception, and Section 5.7.1), •Any intrauterine device (IUD) with published data showing that the expected failure rate is <1% per year (not all IUDs meet this criterion, see the SPM for an example listing of approved IUDs), •Any other method with published data showing that the lowest expected failure rate for that method is less than 1% per year. Any contraception method must be used consistently and in accordance with the approved product label and the instruction of a physician. The potential for drug interaction with background ARTs should also be considered (see Section 5.7.1) All subjects in this study should also be counselled on the practice of safe/safer sex, including the use of effective barrier methods (eg. male condom/spermicide). 9.Subject or the subject’s legal representative is willing and able

Exclusion Criteria

1.Women who are breastfeeding. 2.Any evidence of an active Center for Disease and Prevention Control (CDC) Category C disease. This definition excludes cutaneous Kaposi’s sarcoma (KS) not requiring systemic therapy or current CD4+ cell levels <200cells/mm3 (i.e. subjects with cutaneous KS or <200 CD4+cells/mm3 are eligible for inclusion). 3.Subjects with moderate to severe hepatic impairment as determined by Child-Pugh classification. 4.Anticipated need for HCV therapy during the first 24 weeks of the study. 5.Recent history (<=3 months) of any upper or lower gastrointestinal bleed, with the exception of anal or rectal bleeding. 6.History or presence of allergy or intolerance to the study drugs or their components or drugs of their class. 7.History of malignancy within the past 6 months or ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma; other localized malignancies require agreement between the investigator and Study medical monitor for inclusion of the subject. Subjects with a history of anal intraepithelial neoplasia (AIN) or cervical intraepithelial neoplasia (CIN) may be included in the study. Exclusionary Treatments prior to Screening or Day 1 8.Treatment with an HIV-1 immunotherapeutic vaccine within 90 days of Screening. 9.Treatment with any of the following agents within 28 days of Screening:•radiation therapy,•cytotoxic chemotherapeutic agents,•any immunomodulator. 10.Treatment with any agent, other than licensed ART, with documented activity against HIV-1 in vitro within 28 days of first dose of IP. 11.Treatment with etravirine, efavirenz or nevirapine within 14 days of first dose of IP (etravirine only may be used if co-administered with LPV/RTV or DRV/RTV). 12.Treatment with tipranavir/ritonavir (TPV/RTV), fosamprenavir (FPV) or FPV/RTV within 28 days prior to Screening. 13.Exposure to an experimental drug or experimental vaccine within either 28 days, 5 half-lives of the test agent, or twice the duration of the biological effect of the test agent, whichever is longer, prior to the first dose of IP. 14.French subjects recruited at sites in France will be excluded if the subject has participated in any study using an investigational agent during the previous 60 days or 5 half-lives, or twice the duration of the biological effect of the experimental drug or vaccine - whichever is longer, prior to screening for the study or the subject will participate simultaneously in another clinical study. Exclusionary Lab Values or Clinical Assessments at Screening 15.Any verified Grade 4 laboratory abnormality, with the exception of Grade 4 lipid (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol) abnormalities. A single repeat test is allowed during the Screening period to verify a result. 16.Any acute laboratory abnormality at Screening, which, in the opinion of the Investigator, would preclude the subject’s participation in the study of an investigational compound. 17.Alanine aminotransferase (ALT) >5 times the upper limit of normal (ULN). 18.ALT >= 3xULN and bilirubin >= 1.5xULN (with >35% direct bilirubin).
