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   43851   clinical trials with a EudraCT protocol, of which   7283   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 ).

    General information about the trial
    Main objective of the trial
    Primary objective: To determine the preliminary safety and tolerability profile of multiple oral administrations of rimeporide. Secondary objective:
 To evaluate the pharmacokinetic profile of rimeporide in pediatric patients with DMD.
    Protection of trial subjects
    Prior to enrolment subjects received a full explanation of the nature and purpose of the study, the safety of the drug under investigation, and discussion of any potential therapeutic benefit, and that they were free to withdraw from the study at any time without prejudice. An informed consent form approved by the IEC was signed by the subject and legal representative and the Investigator before any study-related procedures were performed. The Investigator provided copies of the signed informed consent to the subject or legal representative, and the original was retained by the Investigator.

    Recruitment
    Recruitment details
    The recruitment period varied depending on the recruitment speed ; started in March 2016 to November 2017. it was competitive among the 4 sites: France, Spain, Italy and UK. A time interval of at least 1 week was maintained between adminstration of first dose in the first 3 patients of each cohort. It was extended to all patients for cohort 4.

    Pre-assignment
    Screening details
    Screening was carried out within 4 week prior to first administration of rimeporide (SD1) to enable confirmation of patient eligibility and following the signature of the Informed Consent Form.

    Primary: overview of adverse events [1]
    End point description
    End point description: No hypothesis testing performed. Observations are given for the safety population (all patients who received at least one dose of study drug). Categorical data are presented with the number of subjects with at least one event for the following selections: • treatment-emergent AEs (TEAEs) • study drug-related TEAEs (ADRs) • serious TEAEs • study drug-related serious TEAEs (serious ADRs) • TEAEs leading to withdrawal • study drug-related TEAEs (ADRs) leading to withdrawal • serious TEAEs leading to withdrawal • TEAEs leading to death as outcome
    End point type
    Primary
    End point timeframe
    The safety reporting period is defined as the interval between the time of first dosing and the end of the follow-up period. Adverse events falling into this time window are classified as treatment-emergent Adverse Events (TEAE)
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Descriptive statistics only (open label study with analysis of the safety profile of Rimeporide as primary endpoint)
