E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To select a GSK1349572 dose for chronic dosing in infants, children and adolescents that achieves similar exposure to the GSK1349572 adult dose selected from the Phase IIb clinical trial in ART-naïve adult subjects
- To determine the safety and tolerability of GSK1349572 in HIV-1 infected infants, children and adolescents at 24 and 48 weeks.
- To evaluate the steady-state pharmacokinetics of GSK1349572 in combination with other antiretrovirals (OBT) in treatment-experienced HIV-1 infected infants, children and adolescents and to determine the dose of GSK1349572 that achieves a targeted AUC24 (primary PK endpoint) and C24h (secondary PK endpoint) in this population |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the antiviral activity of GSK1349572 in combination with an OBT by measuring virologic response in infants, children and adolescents at 24 and 48 weeks
- To evaluate the effect on immunologic response from baseline to 24 and 48 weeks
- To assess changes in HIV-1 genotype and phenotype to GSK1349572 and other components of the OBT in subjects experiencing virologic failure
- To determine GSK1349572 exposure, its variability and clinical covariates that impact GSK1349572 disposition (e.g. age, weight) using intensive and sparse sampling and population pharmacokinetic analysis
- To determine the extended long term (≥48 weeks) safety and tolerability of GSK1349572 in HIV-1 infected infants, children and adolescents
- To explore the relationship between GSK1349572 exposure and the antiviral activity |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
4.11. >6 weeks to <18 years at study entry
4.12. Confirmed HIV-1 infection defined as positive results from two samples collected at different time points
4.13. ARV treatment experienced (includes those who have received therapy to interrupt maternal-infant transmission) subjects currently on no ART:Must be off treatment ≥ 4 weeks AND must have HIV-1 RNA viral load greater than 1,000 copies/mL of plasma at screening
4.14. ARV treatment experienced subjects currently on ART: Must be on an unchanged, failing therapeutic regimen for at least 8 weeks prior to screening (≤ 1 log drop in HIV-1 RNA within the previous 8 weeks prior to screening) AND must have an HIV-1 RNA viral load greater than 1,000 copies/mL of plasma at screening
4.15. Demonstrated ability or willingness to swallow assigned study medications (tablets or pediatric formulation). NOTE: Tablets MAY NOT be crushed or dissolved.
4.16. Parent or legal guardian able and willing to provide signed informed consent.
4.17. Female subjects who are of child bearing potential and who are engaging in sexual activity that could lead to pregnancy, must use two adequate birth control methods while on study and for 2 weeks after stopping study drug. Hormonal birth control alone (e.g., pills, shots, or slow release inserts placed under/on the skin) would not be considered adequate. An effective, medically accepted barrier method of contraception (e.g., female/male condoms, diaphragm or cervical cap with a cream or gel that kills sperm (excluding nonoxydyl-9), intrauterine device [IUD], others) also must be used during the study. Condoms are recommended because their appropriate use is the only contraception method effective for preventing HIV-1 transmission.
4.18. Males engaging in sexual activity that could lead to HIV-1 transmission must use a condom.
4.19. Subjects must have available at least one fully active drug for the planned optimized background regimen (OBR). Historical genotypes obtained within 1 year of screening will be considered by the study team for determination of fully active drugs if screening genotype testing is inconclusive.

E.4 | Principal exclusion criteria |
4.21. Presence of any active AIDS defining opportunistic infection
4.22. Known ≥ Grade 3 of any of the following laboratory toxicities within 30 days prior to study entry: neutrophil count, hemoglobin, platelets, AST, ALT, lipase, serum creatinine and total bilirubin. A single repeat within the 30 days is allowed for eligibility determination.
4.23. ANY known Grade 4 laboratory toxicities within 30 days prior to study entry.
4.24. The following liver toxicities within 30 days prior to study entry: ALT > 3x ULN AND direct bilirubin is > 2x ULN
4.25. Any prior history of malignancy, with the exception of localized malignancies such as squamous cell or basal cell carcinoma of the skin
4.26. Clinical or symptomatic evidence of pancreatitis, as determined by the clinician
4.27. Use of any disallowed medications at time of screening
4.28. Known history of exposure to integrase inhibitor treatment by the subject or subject’s mother prior to delivery/cessation of breast feeding
4.29. Known resistance to an integrase inhibitor
4.210. Pregnancy or breastfeeding. NOTE: Infants who are receiving breast milk are eligible to enroll
4.211. Subject is currently participating in or has participated in a study with a compound or device that is not commercially available within 30 days of signing informed consent, unless permission from both study teams is granted
4.212. Subject is unlikely to adhere to the study procedures, keep appointments, or is planning to relocate during the study to a non-IMPAACT study site
4.213. Any clinically significant diseases (other than HIV infection) or clinically significant findings during the screening medical history or physical examination that, in the investigator’s opinion, would compromise the outcome of this study
4.214. Subject has used, or anticipates using, chronic systemic immunosuppressive agents or systemic interferon (e.g. for treatment of HCV infection) within 30 days prior to beginning GSK1349572 study treatment. Short courses of corticosteroids (e.g. prednisone or equivalent up to 2 mg/kg/day for 7 days) are permitted.
4.215. Any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol
4.216. Any ARV-treatment naïve subject
