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   43858   clinical trials with a EudraCT protocol, of which   7284   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
    • To demonstrate AST-120, added to standard-of-care therapy in moderate to severe CKD, reduces the risk of progression of CKD as assessed by the development of a component of a triple composite endpoint (initiation of dialysis, kidney transplant, or doubling of sCr), when compared with placebo; and
    • To demonstrate the general safety and tolerability of long-term AST-120 therapy in CKD patients.
    E.2.2Secondary objectives of the trial
    • To evaluate the efficacy of AST-120 in reducing the risk of developing a component of a quadruple composite endpoint (initiation of dialysis, kidney transplant, doubling of sCr, or death) compared with placebo;
    • To evaluate the effects of AST-120 versus placebo, on other measures of renal function i.e. sCr, 24 hr urinary protein excretion, creatinine clearance, urea clearance, and 24 hr urinary creatinine excretion; and
    • To assess the effects of AST-120 versus placebo, on fat-soluble vitamin levels (A, D, E, and K), vitamin B-12, and folate levels.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients that meet all of the following Inclusion Criteria may be enrolled into the study:
    1) Age 18 years or older;
    2) Moderate to severe CKD (in men: sCr ≥ 2.0 mg/dL[≥ 177 µmol/L] and ≤ 5.0 mg/dL[≤ 442 µmol/L]; in women: sCr ≥ 1.5 mg/dL[≥ 133 µmol/L] and ≤ 5.0 mg/dL [≤ 442 µmol/L] ), not anticipated to require dialysis or renal transplant within the next 6 months;
    3) Patient survival expected to be no less than one year;
    4) Serum creatinine in men ≥ 2.0 mg/dL [≥ 177 µmol/L] and ≤ 5.0 mg/dL [≤ 442 µmol/L], and in women ≥ 1.5 mg/dL [≥ 133 µmol/L] and ≤ 5.0 mg/dL [≤ 442 µmol/L], at the initial Screening visit;
    5) Proteinuria / Progressive deterioration in renal function:
    Urinary total protein to urinary total creatinine ratio (both values measured as mg/dL, or other like units) must be ≥ 0.5 on a spot void obtained at the Screening visit
    OR
    If the urinary total protein to urinary total creatinine ratio is <0.5, then the patient may return for a second Screening visit 3 months later. If the sCr value at the second Screening visit is >10% higher than the first Screening visit but not > 5.0 mg/dL [≤ 442 µmol/L] or if the urinary total protein to urinary total creatinine ratio is ≥ 0.5, then the patient may be enrolled (See Appendix E in the Protocol for a listing of qualifying sCr values based on initial and second Screening visit values).
    6) Sitting blood pressure ≤ 160/90 mmHg at both Screening and Baseline visits. In addition, blood pressure, if measured, must have been stable in hypertensive patients over the 3 months prior to Screening, with no more than 1 blood pressure reading > 160/90 mmHg;
    7) In patients being treated for hypertension, they should be on a stable anti-hypertensive regimen, defined as no changes in anti-hypertensive medications or doses in the last 3 months prior to the Baseline visit, and to include a stable dose of either an ACEI or ARB unless contraindicated;
    8) Stable nutritional status; and
    9) Willingness to comply with the study and sign a written informed consent.
    E.4Principal exclusion criteria
    Patients that meet any of the following Exclusion Criteria must not be enrolled into the study:
    1) Obstructive or reversible cause of kidney disease;
    2) Nephrotic syndrome defined as a ratio of urinary total protein to urinary creatinine (both components measured as mg/dL or other like units) of > 6.0 as measured on a spot void;
    3) Adult polycystic kidney disease;
    4) History of previous kidney transplant;
    5) History of alcohol or drug abuse within the past 12 months;
    6) Known human immunodeficiency virus (HIV) infection;
    7) Received immunosuppressive therapy (including systemic corticosteroids for more than 5 days at a daily dose in excess of 0.1 mg/kg, prednisone equivalent) in the past 3 months, or anticipated to require such treatment during the study course;
    8) History of recent (within the past 6 months) accelerated or malignant hypertension;
    9) Patients who are likely to require changes in ACEI or ARB regimens during the course of this study;
    10) Uncontrolled arrhythmia or severe cardiac disease (New York Heart Association Class III -IV), including myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft, cerebrovascular accident, or transient ischemic attack within the past 6 months;
    11) History of malabsorption, inflammatory bowel disease, hiatal hernia, active peptic ulcer, or severe GI dysmotility, not attributable to the use of a phosphate binder;
    12) History of cancer within the past 5 years (cervical carcinoma in situ, low-grade cutaneous malignancy, or other low grade malignancy are exemptions);
    13) Alanine transaminase (ALT) or aspartate transaminase (AST) values > 2.5 times the upper limit of normal (ULN);
    14) Received any investigational agent or participated in a clinical study within the previous 3 months;
    15) Presence of any significant medical condition that might create an undue risk with study participation, or significantly confound the collection of safety and efficacy data in this study; or
    16) For women of childbearing potential, a positive pregnancy test result of serum beta human chorionic gonadotropin (βHCG) or unwillingness to use approved single barrier or oral contraception, or unwillingness to be sexually abstinent.
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint will be the occurrence of one component of a triple
    composite of renal outcomes: initiation of dialysis, kidney transplantation,
    or doubling of sCr from the value obtained at the Baseline visit (Visit 2).
    The initial doubled (from Baseline) sCr result will be verified 5-10 days
    later with another sCr sampling. If this result remains doubled, a
    confirmatory measurement of sCr doubling will occur at 4-6 weeks after
    the initial doubled result was reported. If the Baseline value is not
    available for comparison, the value obtained at the Screening visit (Visit 1)
    will be used, If a second screening visit is performed then that screening
    value will be used. An Endpoint Adjudication Committee (EAC) will review
    and adjudicate all potential endpoint events.
