You may be eligible if
Be able to understand and comply with protocol requirements, instructions, and restrictions;
Be likely to complete the study as planned;
Be considered appropriate candidates for participation in an investigative clinical trial with oral medication (e.g., no active substance abuse, acute major organ disease, or planned long-term work assignments out of the country, etc.).
Signed and dated written informed consent is obtained from the subject or the subject's legal representative prior to screening
HIV-1 infected men or women \>=18 years of age;
A female may be eligible to enter and participate in the study if she: a. Is of non-childbearing potential either defined as 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,
A female may be eligible to enter and participate in the study if she: b. Is of childbearing potential with a negative pregnancy test at both Screening and Day 1 and agrees to use one of the following methods of contraception to avoid pregnancy: Complete abstinence from intercourse from 2 weeks prior to administration of study drug, throughout the study, and for at least 2 weeks after discontinuation of all study drugs; Double barrier method (e.g., male condom/spermicide, male condom/diaphragm, diaphragm/spermicide); Any intrauterine device (IUD) with published data showing that the expected failure rate is \<1% per year ; Male partner sterilization prior to the female subject's entry into the study and this male is the sole partner for that subject; Approved hormonal contraception for subjects randomly assigned to the ABC/DTG/3TC arm or approved hormonal contraception plus a barrier method for subjects assigned to continued antiretroviral therapy arm; Any other method with published data showing that the expected failure rate is \<1% per year.
Any contraception method must be used consistently, in accordance with the approved product label and for at least 2 weeks after discontinuation of study drug. A childbearing potential female subject who starts the study using complete abstinence as her contraceptive method and decides to become sexually active must use the double barrier method either as a bridge to an approved hormonal contraception (if possible) or as a method of choice to be maintained from that moment onwards.
All subjects participating in the study should be counselled on safer sexual practices including the use of effective barrier methods (e.g., male condom/spermicide).
Within the last year, 2 consecutive plasma HIV-1 Ribonucleic acid (RNA) measurements \<50 copies/millilitres (c/mL) and plasma HIV-1 RNA\<50 c/mL at Screening (\<75 b Deoxyribonucleic acid \[bDNA\] is considered equal to \<50 c/mL); Subjects who present at initial screening with a viral load between 50 to 200 c/mL can be retested once within the screening period.
Must be on current regimen (whether first or second line Combination antiretroviral therapy \[cART\]) for at least 6 months prior to Screening;
Acceptable stable cART regimens prior to Screening include: • Boosted PI (or Atazanavir \[ATV\]) unboosted) + 2 NRTIs, NNRTI + 2 NRTIs, • INI + 2 NRTIs. For subjects on an INI, their INI at Screening must be RAL or Elvitegravir (EVG)
Any switch to a second line regimen, defined as change of a single drug or multiple drugs simultaneously, must have occurred due to tolerability and/or safety concerns.
Subject must have achieved plasma HIV-1 RNA level \<50 c/mL within 6 months of start of initial cART regimen with no plasma HIV-1 RNA level \>200 c/mL following initial suppression;
Documentation that the subject is negative for the human leukocyte antigen (HLA) B\*5701 allele;
You may not be if
Exclusionary Medical Conditions
Women who are breastfeeding;
Any evidence of an active (Centers for Disease Control and Prevention \[CDC\] Category C) disease. Exceptions include cutaneous Kaposi's sarcoma not requiring systemic therapy and historic CD4+ cell counts of \<200 cells/cubic millimeter (mm).
Subjects with any degree of hepatic impairment;
Subjects positive for hepatitis B virus surface antigen (+HBsAg) at Screening or with an anticipated need for hepatitis C virus (HCV) therapy during the study;
History or presence of allergy to the study drugs or their components or drugs of their class;
Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical intraepithelial neoplasia; other localized malignancies require agreement between the investigator and the study medical monitor for inclusion of the subject;
Subjects who, in the investigator's judgment, pose a significant suicidality risk. Recent history of suicidal behavior and/or suicidal ideation may be considered as evidence of serious suicide risk;
Exclusionary Treatments Prior to Screening or Day 1
Treatment with an HIV-1 immunotherapeutic vaccine within 90 days of Screening;
Treatment with any of the following agents within 28 days of Screening: radiation therapy, cytotoxic chemotherapeutic agents, any immunomodulators that alter immune responses;
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 study drug;
A history of use of only mono or dual NRTI therapy prior to starting cART;
Use of etravirine at time of switch;
Use of DTG at time of switch;
Subjects receiving any prohibited medication listed in the protocol and who are unwilling or unable to switch to an alternate medication
Exclusionary Laboratory Values or Clinical Assessments at Screening
Evidence of primary viral resistance based on the presence of any resistance-associated major PI or any NRTI, NNRTI, or INI mutation in any prior resistance genotype assay result;
Any verified Grade 4 laboratory abnormality, with the exception of Grade 4 triglyceride abnormalities. A single repeat test is allowed during the screening period to verify a result;
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;
Alanine aminotransferase (ALT) \>=5 times the upper limit of normal (ULN), or ALT \>=3 × ULN and bilirubin \>=1.5 × ULN (with \>35% direct bilirubin);
Subject has CrCl of \<50 mL/min using Modification of Diet in Renal Disease (MDRD);
QTc (Bazett) \>=450 msec or QTc (Bazett) \>=480 msec for subjects with bundle branch block. The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB). The QTc should be based on a single QTc value electrocardiogram (ECG) obtained.
