Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   37738   clinical trials with a EudraCT protocol, of which   6184   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to evaluate the effect of TAK-475 QD compared to placebo on low-density lipoprotein cholesterol (LDL-C) in subjects with HoFH when co-administered with current lipid-lowering therapy for 12 weeks.
    E.2.2Secondary objectives of the trial
    To evaluate the safety and tolerability of TAK-475 compared to placebo during a 12-week double-blind treatment period when co-administered with current lipid-lowering therapy. The long-term safety of TAK-475 treatment in this population will continue to be evaluated during the open-label extension period. To evaluate the effect of TAK-475 compared to placebo on other lipid variables: total cholesterol (TC), triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), very-low density lipoprotein cholesterol (VLDL-C), lipoprotein (a), apolipoprotein A1 (Apo A1) and apolipoprotein B (Apo B) during a 12-week double-blind treatment period.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    1. Subjects must be at least 8 years of age and weigh ≥ 30kg

    2. Subjects must have homozygous FH documented by genetic testing confirming 2

    mg/dL (11.91 mmol/L)
    • Tendinous xanthomas and/or corneal arcus before 10 years of age and /or
    premature coronary heart disease before 20 years of age.

    3. Subjects must have read and understood the Subject Information Sheet / Informed Consent and signed the Informed Consent Form. If the subject is considered a minor, a minor assent form should be executed by the minor and a parent or legal guardian must also give their full consent in writing in accordance with applicable laws and regulations.

    4. Subjects must have been taking a stable, approved lipid-lowering drug regimen for a minimum of 8 weeks prior to Screening Visit 1 and will continue to do so for the
    duration of the study.

    5. If female and of childbearing potential, the subject is not pregnant, not lactating, not planning on becoming pregnant and agrees to use adequate contraception (as defined in the informed consent form) between Screening Visit 1 and 30 days following the last dose of study medication.

    6. The subject is capable of understanding and complying with protocol requirements.
    E.4Principal exclusion criteria
    1. The subject has an alanine aminotransferase (ALT) or aspartate aminotransferase
    (AST) levels > 2 times the upper limit of normal (ULN), active liver disease,
    jaundice, or serum creatinine > 135 ╬╝mol/L (1.5mg/dL) at screening.

    2. The subject has a CPK > 3 times the ULN at screening. A repeat test for any of these tests described in the first two criteria is permitted and is at the discretion of the investigator.

    3. The subject has a positive hepatitis B surface antigen, or hepatitis C virus antibody, as determined by medical history and/or subject’s verbal report.

    4. The subject has a positive human immunodeficiency virus (HIV) status or is taking
    antiretroviral medications, as determined by medical history and/or subject’s verbal

    5. The subject is unable or unwilling to discontinue excluded medications (see Section
    7.4) or to continue stable doses of “stable dose” medications or would require treatment with any excluded medication during the study.

    6. The subject is currently participating in another investigational study or has
    participated in an investigational study within the past 30 days or, for drugs with a
    long half-life, within a period of less than 5 times the drug’s half-life.

    7. The subject has a previous history of cancer that has been in remission for less than 5 years prior to the first dose of study drug. This criterion does not include those subjects with basal cell or Stage 1 squamous cell carcinoma of the skin.

    TSH is >1.5 x ULN, a free T4 level will be determined and if the free T4 is within
    normal limits the subject may continue in the study.

    11. The subject has uncontrolled hypertension despite medical treatment (defined for
    adults as mean resting diastolic blood pressure >100 mm Hg or mean resting systolic
    blood pressure >160 mm Hg) at Screening Visit 1.

    12. The subject has inflammatory bowel disease or any other malabsorption syndrome or has had gastric bypass or any other surgical procedure for weight loss.

    15. The subject has any other serious disease or condition at screening or at
    randomization that might reduce life expectancy, impair successful management according to the protocol or make the subject an unsuitable candidate to receive
    study drug.
