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.

    mutants (K103N, Y181C, and L100I)
    MedDRA Classification
    E.1.2 Medical condition or disease under investigation
    E.1.2Version 9.1

    E.1.2Classification code 10020161
    E.1.2Term HIV infection
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to assess efficacy of UK-453,061 when used in combination with tenofovir DF/emtricitabine, as measured by percentage of subjects with HIV-1 RNA <48 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 <48 and <400 copies/mL.
    • Change from baseline in log10 transformed HIV-1 RNA levels.
    • 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
    1. Molecular Profiling Supplement, Version and Date: Final 28 July 2008

    The primary objective of this additional research component is to collect, store, and use samples to investigate possible associations between genomic and metabonomic variation:
    • in relation to response to the study drugs, and
    • in relation to characteristics of the disease/condition under study in the associated clinical trial, and related conditions.

    In addition, samples may be used as controls in genomic and metabonomic investigations of the causes, natural history, and other aspects of important diseases and conditions for which Pfizer is researching new or improved drug therapies.

    Scientific information about these differences among groups of subjects can help researchers to better understand the response of subjects to investigational drugs and to learn more about diseases/conditions for which we are developing treatments.

    Samples collected will be stored in Pfizer’s Exploratory Research Biobank in the USA.

    2. 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 COBAS®
    AmpliPrep/COBAS® TaqMan® HIV-1 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 28 days 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.
