Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43886   clinical trials with a EudraCT protocol, of which   7296   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    The primary objective is to assess efficacy of UK-453,061 when used in combination with tenofovir DF/emtricitabine, as measured by the percentage of subjects with HIV-1 RNA <50 copies/mL at 48 weeks.
    E.2.2Secondary objectives of the trial
    • To assess efficacy as measured by percentage of subjects with HIV-1 RNA <50 and <400 copies/mL.
    •To assess Change from baseline in log10 transformed HIV-1 RNA levels.
    •To assess safety and tolerability of UK-453,061.
    • To assess the pharmacokinetic (PK) and pharmacokinetic/ pharmacodynamic (PK/PD) relationship of UK-453,061.
    • To assess pharmacokinetic parameters of UK-453,061 AUC24,Cmax and C24h (PK substudy).
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    There is a PK sub-study written within the same protocol (A5271015).
    E.3Principal inclusion criteria
    Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the trial:
    1. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
    2. Male or female at least 18 years of age available for a follow-up period of at least
    96 weeks.
    3. HIV-1 RNA viral load of ≥1,000 copies/mL measured by the Roche Roche Amplicor® HIV-1 Monitor test at the screening visit.
    4. Negative urine pregnancy test at the Day 1 visit, prior to receiving the first dose of study medication, for Women of Child Bearing Potential (WOCBP).
    • NOTE: WOCBP includes any female who has experienced menarche and who has not undergone successful surgical sterilization or is not post-menopausal (ie, no menstrual periods for at least 2 years). Even women who are using oral, implanted or injectable contraceptive hormones or mechanical products (intrauterine devices; barrier methods: eg,condom or diaphragm with spermicide) to prevent pregnancy, who are practicing abstinence, or who have a partner that is sterile (eg, vasectomy), should be considered to be of child bearing potential.
    5. Effective barrier contraception for WOCBP and males. In addition, WOCBP must use another acceptable method of contraception for the duration of the study and for 12 weeks after leaving the study. Acceptable contraception includes, but is not limited to, oral, implanted or injectable hormone therapy and intrauterine devices.
    6. Subjects who are willing and able to comply with scheduled visits, treatment plan,
    laboratory tests, and other study procedures.
    E.4Principal exclusion criteria
    Key Exclusion Criteria have been selected (please refer to Protocol for the completed list):

    Subjects presenting with any of the following will not be included in the trial:
    1. Suspected or documented active, untreated HIV-1 related OI or other condition requiring acute therapy at the time of randomization with the following exceptions:
    •Subjects on a stable (>30 days) secondary OI prophylaxis regimen or chronic treatment.
    •Subjects on a primary OI prophylaxis regimen of any duration. However, subjects being treated with trimethoprim-sulfamethoxazole must be on stable therapy (>60 days) to be eligible.
    2. Subjects on therapy for Hepatitis B.
    3. Subjects with acute Hepatitis B and/or C within 30 days of randomization.
    4. Subjects with Hepatitis C on therapy with interferon and/or ribavirin for <60 days.
    However, subjects diagnosed with Hepatitis C may be treated for Hepatitis C during the study if deemed appropriate by the subject’s physician.
    5. Absolute CD4+ cell count <200 cells/mm3.
    6. Treatment for an active OI, or unexplained temperature >38.5 °C, for 7 consecutive days within 30 days prior to randomization.
    7. Prior treatment with efavirenz, emtricitabine, or tenofovir DF, or with any other antiretroviral therapy for more than 14 cumulative days at any time.
    12. Malignancy requiring systemic therapy that must be continued during the trial.
    14. Renal insufficiency defined as a serum creatinine greater than 3 times the upper limit of normal or creatinine clearance of less than 50mL/min. Creatinine clearance will be calculated by the Investigator using the Cockcroft and Gault equation
    15. Total bilirubin greater than 1.5 times the upper limit of normal.
    16. AST and/or ALT greater than 3 times the upper limit of normal.
    17. Male subjects with a baseline QT of >450 msec and female subjects with a baseline QT of >470 msec.
    18. Presence of risk factors for prolongation of QT interval including heart failure, chronic hypokalemia, family history of long QT syndrome, concomitant use of medications that are known to prolong QT interval.
    24. Presence of gross hematuria or grade 4 proteinuria at the time of screening.
    30. Contraindicated medications being taken by the subject at the time of randomization that must be continued during the study period, including immunomodulators for the treatment of HIV-1 infection. Interferon for the ongoing treatment of hepatitis C infection is permitted.
    Note: It is incumbent upon the investigator to be thoroughly familiar with the prescribing information for the study drugs.
