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   38003   clinical trials with a EudraCT protocol, of which   6235   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Radiocontrast-induced nephropathy
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine how oral and intravenous acetylcysteine affects renal function in healthy volunteers and people with chronic kidney disease (CKD), in the presence and absence of radiocontrast.
    E.2.2Secondary objectives of the trial
    To identify a rational dose of acetylcysteine, given through the correct route, and assessed using the correct outcome measure, that can be studied in a large phase III trial of acetylcysteine in radiocontrast-induced nephropathy.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    The study will be performed simultaneously in five groups of participants (Appendix 1), studying:

    1. healthy volunteers receiving acetylcysteine PO, acetylcysteine IV, or placebo.

    2. volunteers with stage III CKD receiving acetylcysteine PO, acetylcysteine IV, or placebo.

    3. healthy volunteers receiving IV radiographic contrast plus acetylcysteine PO, acetylcysteine IV, or placebo.

    4. patients with stage III CKD receiving radiographic contrast for elective coronary angiography plus acetylcysteine PO, acetylcysteine IV, or placebo.

    5. patients with stage III CKD receiving radiographic contrast for elective CT plus acetylcysteine PO, acetylcysteine IV, or placebo.

    Studies 1-3 of this protocol are randomised, placebo controlled, three-way cross-over, human volunteer studies. Each study will have three arms, participants being randomised to receive all three treatments on three different occasions:

    A) placebo capsules PO, plus an IV infusion acetylcysteine in normal saline.
    B) acetylcysteine capsules PO, plus an infusion of normal saline.
    C) placebo capsules PO, plus an infusion of normal saline.

    Studies 4 and 5 are randomised, placebo controlled, three-way parallel group study in patients undergoing elective coronary angiography and CT.

    Participants in Studies 4 and 5 will be randomised to one arm only.

    Sufficient participants will be recruited to studies 1, 2 and 3 to obtain full data on eight volunteers in each study. Sufficient participants will be recruited to study 4 to obtain full data on twenty-four patients, eight in each arm. Sixty-six patients will be recruited to study 5, twenty-two in each arm.
    E.3Principal inclusion criteria
    Studies 1 & 3:
    Healthy male volunteers aged over 45 years, with a BMI between 22 and 40.

    Study 2:
    Male volunteers aged over 45 years, with stable CKD stage III and a BMI between 22 and 40, not on metformin.

    Study 4:
    Male patients aged over 45 years, with stable CKD stage III and a BMI between 22 and 40, not on metformin, undergoing elective coronary angiography.

    Study 5:
    Male patients aged over 45 years, with stable CKD stage III and a BMI between 22 and 40, not on metformin, undergoing elective CT.
    E.4Principal exclusion criteria
    Volunteers for Studies 1, 3
    · lack of informed consent
    · age <46 years
    · current involvement in a clinical trial
    · clinically significant co-morbidity: heart failure, hypertension, known
    hyperlipidaemia, diabetes mellitus, coagulopathy or bleeding disorder.
    · thyroid disease, myasthenia gravis, asthma, atopy, or a history of
    allergy/sensitivity to acetylcysteine or contrast medium
    · current intake of prescription medicines
    · recent infective/inflammatory condition
    · blood donation during the preceding three months

    Patients for Studies 2, 4 and 5
    · lack of informed consent
    · age <46 years
    · current involvement in a clinical trial
    · thyroid disease, myasthenia gravis, asthma, atopy, or a history of
    allergy/sensitivity to acetylcysteine or contrast medium
    · current intake of metformin
    · recent infective/inflammatory condition
    · blood donation during the preceding three months
    E.5 End points
    E.5.1Primary end point(s)
    Changes in RBF will be the primary outcome since we expect this measure to be the most sensitive to the effects of acetylcysteine and/or contrast administration.
