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   43976   clinical trials with a EudraCT protocol, of which   7312   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The objective of this trial is to evaluate the lipid lowering efficacy and safety of colesevelam HCl therapy administered to heFH pediatric patients 10 through 17 years of age who are on a stable dose of a pediatric-approved statin monotherapy (atorvastatin, lovastatin, simvastatin, or pravastatin), or who are treatment naïve to lipid-lowering therapy. For Period II (Day 1 to Week 8): To evaluate the low density lipoprotein cholesterol (LDL-C) lowering efficacy of colesevelam HCl administered to heFH patients on a stable dose of statins or who are treatment naïve to lipid lowering therapy.
    E.2.2Secondary objectives of the trial
    For Period III (Week 8 to Week 26): To evaluate the long-term safety and efficacy of high dose colesevelam HCl administered to heFH patients while optimizing statin therapy for treatment to goal.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Written informed consent from the patient’s parent or guardian and assent from the patient. (Consent form is approved by the institutional review board (IRB) or other committee).

    2. Male or female patient is 10 through 17 years of age.

    3. Patient has a diagnosis of heFH defined as a known mutation in a copy of the patient’s LDL-receptor or apolipoprotein B (Apo B) gene. In the absence of a genetic diagnosis the patient must have the following LDL-C criteria to be classified as a heFH patient:
    • A documented history of untreated LDL-C >160 mg/dL (4.14 mmol/L) In combination with at least one of the following:
    • The history or presence, in the patient or a first degree relative, of a documented tendinous or cutaneous xanthoma or premature (before age 45 years) corneal arcus; or
    • The history or presence, in an adult first-degree relative or biological offspring of a documented mutation in a copy of the individual’s (relative or offspring) LDL-receptor or apolipoprotein B (Apo B) gene; or
    • The presence, in an adult first-degree relative, of documented untreated LDL-C >190 mg/dL (4.9 mmol/L), or sibling <18 years old with LDL-C >160 mg/dL (4.14 mmol/L); or
    • A documented history, in a first-degree relative, of premature coronary artery disease or sudden death from natural causes prior to age 55 years if male, or prior to age 60 years of age if female.

    4. Patient has LDL-C >130 mg/dL (3.37 mmol/L) while on statin therapy, or LDL-C >160 mg/dL (4.14 mmol/L) naïve to hypolipidemic therapy and diet stabilized.

    5. Patient must be stable on a statin plus diet for 6-weeks; or for lipid-lowering treatment naïve patient, stable on a NCEP Step 1 diet or equivalent for 4 weeks prior to Visit 1.

    6. Triglycerides (TG) at Visit 1 <250 mg/dL (2.83 mmol/L).

    7. Patients should be of at least Tanner Stage 2.

    8. Female patients may enroll if all 5 of the following criteria are met:
    • At least 1 year post-menarche
    • Negative urine pregnancy test at screening
    • Not lactating
    • Do not plan to become pregnant during the study
    • Use appropriate contraceptive methods if sexually active. If the patient is on oral contraceptives, it needs to be taken at least 3 months prior to randomization.

    9. Mean treatment compliance during Period I (Visit 2 and Visit 3) must be ≥75%.
    E.4Principal exclusion criteria
    1. Patients unable or unwilling to take the study drug.

    2. Secondary hyperlipidemia (e.g., due to biliary cirrhosis, dietary abnormalities, nephrotic syndrome, hypothyroidism, etc.).

    3. Fasting TG >250 mg/dL (2.83 mmol/L).

    9. Poorly controlled Type 1 or Type 2 diabetes mellitus defined as HbA1c >9.0%. Diabetics must have documentation of HbA1c within 3 months of the screening visit. Undocumented patients must have their HbA1c assessed at Visit 1. Note: Patients with Type 1/Type 2 diabetes controlled with insulin and/or oral hypoglycemic agents on a stable dose for last 30 days prior to Visit 1 may be included.

    10. Patients who require or are taking any concomitant medication, which may interfere with the objectives of the study. Use of oral anticoagulants or digoxin, unless the dose has been stable for 4 weeks prior to Visit 1 and regular clinical laboratory monitoring is performed.

    11. Screening laboratory values within the following age/gender appropriate reference ranges as assessed by the central laboratory:
    • Hemoglobin
    Male <10 g/dL
    Female <9 g/dL
    • Alanine Transaminase (ALT) (SGPT) >2 x Upper Limit Normal(ULN) for age
    • Aspartate Transaminase (AST) (SGOT) >2 x ULN for age
    • Alkaline Phosphatase >2 x ULN for age
    • Total bilirubin >1 x ULN (unless elevations due to congenital bilirubin metabolism defect, i.e. Gilbert Syndrome)
    • Creatine Phosphokinase (CPK) >5 x ULN for gender unless explained by exercise
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint for this trial in pediatric patients with heFH is that after 8 weeks of treatment (Period II), all patients receiving low dose (1875 mg) and high dose (3750 mg) colesevelam HCl will demonstrate superior lipid-lowering efficacy compared with patients treated with placebo as assessed by percent change from baseline in LDL-C reduction.
