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   40657   clinical trials with a EudraCT protocol, of which   6636   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
    To study the effects Pentoxifylline in ESA resistant ESRD patients on haemodialysis.

    The primary study endpoints is the ESA requirement relative to the Hb level (is there a difference in a randomised placebo controlled cross-over study)?
    E.2.2Secondary objectives of the trial
    Secondary endpoints include:
    • Safety analysis
    • Hb values and ESA doses after 6 months of treatment.
    • Blood sampling will be performed at the start of each hemodialysis session every month. These samples may be subjected to additional analyses to further characterize the pro- and anti-inflammatory effects of pentoxifylline including CRP.
    • DNA telomere length shortening
    • Radiological imaging will be performed at Baseline and at 6 months. The effect IMP has on the following radiological parameters will be examined:
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Be able to read and understand the written consent form, complete study-related procedures, and communicate with the study staff;
    • Willing to comply with study restrictions;
    • Between 18 and 65 years of age (inclusive).
    • Diagnosis of clinically stable ESRD, as determined by the investigator;
    • Requiring regular dialysis therapy for at least 12 weeks prior to first administration of study agent;
    • Receiving treatment with IV or SC erythropoietin receptor agonist at least weekly (ie exclude Micera or other ESAs given fortnightly or monthly) for a minimum of 8 weeks prior to administration of study agent, requiring doses to remedy EPO-resistance (requiring >12,000iu equivalent of EPO per week), with evidence of stable hemoglobin levels;
    • Baseline hemoglobin values between 9.0 and 12.0 g/dL before entering the study;
    • CRP levels of ≥5 mg/L
    E.4Principal exclusion criteria
    • Clinically relevant abnormal history of physical and mental health other than conditions related to chronic kidney disease of patient, as determined by medical history taking (as judged by the investigator);
    • Clinically relevant abnormal laboratory results, ECG, vital signs, or physical findings other than conditions related to chronic kidney disease of patient (as judged by the investigator);
    • Subject has uncontrolled hypertension;
    • Subject is unable to refrain from the use of disallowed concomitant medication from one week prior to the first study drug administration until follow-up assessments (see section 3.3);
    • Participation in an investigational drug trial in the 3 months prior to administration of the initial dose of study drug that might interfere with the primary or secondary endpoints;
    • Subject has undergone major surgery within six months prior to screening;
    • Any other condition that in the opinion of the investigator would complicate or compromise the study (e.g. known haemoglobinopathy), or the well being of the subject.
    • Females of child-bearing potential who are not willing to use contraception for the duration of the study.
    • Subject is known hypersensitivity to the active constituent, pentoxifylline other methyl xanthines or any of the excipients.
