E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To select a GSK1349572 once daily dose for further evaluation in Phase III based on a comparison of the Week 16 antiviral activity and tolerability of a range of oral doses of GSK1349572 in HIV-1 infected therapy-naïve adult subjects. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect of various GSK1349572 doses on selected virological and immunological markers of HIV infection through Week 16, Week 24 and Week 48 To evaluate the safety and tolerability of GSK1349572 doses through Week 16 To characterize the PK parameters of GSK1349572 using intensive and sparse PK sampling strategies and to explore exposure-response relationships To confirm the Week 16 GSK1349572 once daily selected dose at Week 24 based on antiviral activity in conjunction with immunologic, safety and PK measures To assess the development of viral resistance to GSK1349572 and other on-study ARTs in subjects experiencing virological failure To evaluate the effect of various demographic factors on exposure-response parameters of GSK1349572 To assess the HIV-1 RNA decay rate over the initial 2 weeks of treatment To evaluate the antiviral activity, safety, tolerability and development of viral resistance of the selected dose of GSK1349572 relative to EFV over time

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. HIV-1 infected adults > 18 years of age. A female is eligible to enter and participate in the study if she falls into one of the following categories: a. Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation, hysterectomy or bilateral oophorectomy or post-menopausal defined as 24 months of spontaneous amenorrhea; or, b. Child-bearing potential, with a negative pregnancy test at screen and a negative pregnancy test at Day1, who agrees to use one of the methods of contraception listed in the protocol. Premenarchal females who develop child-bearing potential while on study will also be expected to follow one to the methods of contraception listed in the protocol. 2. HIV-1 infection with a screening plasma HIV-1 RNA ≥1000 c/mL 3. CD4+ cell count ≥200 cells/mm3 (or higher as local guidelines dictate) 4. ART-naive defined as having <10 days of prior therapy with any antiretroviral agent. Any previous exposure to an HIV integrase inhibitor other than GSK1349572 will be exclusionary. 5. Subject has no evidence of viral resistance to any antiretroviral drug indicative of primary transmitted resistance in screening genotype or historical resistance test result 6. Able to understand and comply with protocol requirements, instructions, and protocol-stated restrictions and is likely to complete the study as planned 7. Signed and dated written informed consent is obtained from the subject or the subject’s legal representative prior to screening. 8. French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.

E.4 | Principal exclusion criteria |
1. Any pre-existing mental, physical, or substance abuse disorder which may interfere with the subject’s ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the subject 2. Women who are pregnant or breastfeeding 3. Any evidence of an active CDC Category C disease except cutaneous Kaposi’s sarcoma not requiring systemic therapy at the screening visit. 4. Previous participation in an experimental drug and/or vaccine trials (s) within 30 days or 5 half-lives, or twice the duration of the biological effect of the experimental drug or vaccine, whichever is longer 5. History of ongoing or clinically relevant pancreatitis or hepatitis within the previous 6 months, including chronic HBV infection. 6. Serious medical condition which would compromise the safety of the subject 7. Any condition which may interfere with the ADME of the drug or render the subject unable to take oral medication. 8. Any acute laboratory abnormality at screening, which would preclude the subject’s participation in the study of an investigational compound. 9. History of upper gastrointestinal bleed (unless in the opinion of the Investigator and Sponsor the primary cause was reversible and has been adequately treated) and/or subjects with active peptic ulcer disease 10. Subject has estimated creatinine clearance <50 mL/min 11. ALT ≥5 times ULN. Subjects with ALT > 2xULN but <5xULN may participate in the study if the abnormality will not interfere with the study procedures or compromise subject safety 12. Screening ALT ≥3xULN and bilirubin ≥1.5xULN 13. Lipase >3xULN 14. Hemoglobin <100 g/L(10g/dL) 15. History or presence of allergy or intolerance to the study drugs or drugs of their class, or a history of drug or other allergy that contraindicates participation. 16. Treatment with radiation therapy or cytotoxic chemotherapeutic agents within 28 days prior to screening, or has an anticipated need during the study 17. Required treatment with immunomodulators within 28 days or subject has received an HIV-1 immunotherapeutic vaccine within 90 days 18. Treatment with foscarnet, hydroxyurea or other agents with documented activity against HIV-1 in vitro within 28 days of study administration 19. History of the following cardiac diseases: myocardial infarction, congestive heart failure, documented hypertrophic cardiomyopathy, sustained ventricular tachycardia 20. Personal or family history of prolonged QT syndrome 21. Any clinically significant finding on screening or baseline ECG 22. Significant blood loss within a 56 day period 23. Immunization within 30 days 24. French subjects: The subject has participated in any study using an investigational drug 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. |

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of subjects with HIV-1 RNA <50 c/ml through Week 16 using the TLOVR algorithm. Dose selection will be based primarily on antiviral activity and tolerability in conjunction with immunologic, safety and PK measures will also be considered. |
