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   44039   clinical trials with a EudraCT protocol, of which   7319   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.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the study is to evaluate the long-term safety, tolerability, and effect on intravascular hemolysis (ie, proportion of patients achieving lactate dehydrogenase (LDH) ≤ 1.5× upper limit of normal (ULN) over 26 weeks) of REGN3918 in patients with paroxysmal nocturnal hemoglobinuria (PNH).
    E.2.2Secondary objectives of the trial
    The secondary objectives of the study are:
    •To evaluate the long-term effect of REGN3918 on intravascular hemolysis.
    •To assess the concentrations of total REGN3918 in serum.
    •To evaluate the occurrence of the immunogenicity of REGN3918.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    There are optional future biomedical research and pharmacogenomic analysis sub-studies . Subjects will be required to sign separate sub-study ICFs before collection of samples. There is no separate protocol.
    The purpose of the pharmacogenomic analyses is to identify genomic associations with clinical (safety or efficacy) or biomarker response to REGN3918, the complement pathway, PNH and related complement mediated diseases, clinical outcome measures, and possible AEs.
    There will not be separate sub-study protocols.
    E.3Principal inclusion criteria
    1. Patients with PNH who have completed, without discontinuation, study treatment in one of the parent studies in which they participated
    2. Willing and able to comply with clinic visits and study related procedures
    3. Provide informed consent signed by study patient

    E.4Principal exclusion criteria
    1. Significant protocol deviation(s) in the parent study based on the investigator’s judgment and to the extent that these would (if continued) impact the study objectives and/or safety of the patient (for example, repetitive non-compliance with dosing by the patient).
    2. Any new condition or worsening of an existing condition which, in the opinion of the investigator, would make the patient unsuitable for enrollment or could interfere with the patient participating in or completing the study.
    E.5 End points
    E.5.1Primary end point(s)
    The primary safety endpoint is incidence and severity of treatment-emergent adverse events (TEAEs) and other safety variables during the 2-year open-label treatment period of the study in patients treated with REGN3918.
    The primary efficacy endpoint is the proportion of patients achieving LDH ≤1.5×ULN over week 26, defined as LDH ≤1.5×ULN at every scheduled time point up to week 26 (inclusive)
    E.5.1.1Timepoint(s) of evaluation of this end point
    2 years for the primary safety endpoint
    26 weeks for the primary efficacy endpoint
    E.5.2Secondary end point(s)
    The secondary endpoints include:
    •The proportion of patients with breakthrough hemolysis over week 26
    •The rate and number of units of transfusion over week 26
