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   43857   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 ).

    General information about the trial
    Main objective of the trial
    The primary objective was to evaluate the rate of complete remission (CR) and complete remission with incomplete blood count recovery (CRi) on two different dosing schedules of sonidegib in acute leukemia.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.

    Primary: Rate of complete remission (CR)

    End point title
    Rate of complete remission (CR) [1]
    End point description
    Complete Response (CR) was based on the International Working Group (IWG) criteria based on weekly peripheral blood count measurements and bone marrow biopsy/aspiration collection. Efficacy assessments were performed to determine CR. A treatment cycle was defined as 4 weeks. The outcome measure for the study is based on standardized response criteria as defined by the International Working Group (IWG) for AML. The IWG was established by a group of investigators interested in the design and conduct of clinical trials in acute myeloid leukemia (AML). The criteria established by this group (a set of recommendations for response assessment) are well established, endorsed by major institutions and Health Authorities, and are widely used in clinical trials. No statistical analysis was planned for this primary outcome.
    End point type
    Primary
    End point timeframe

    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.

    The other primary efficacy endpoint was CRi based on the International Working Group (IWG) criteria based on weekly peripheral blood count measurements and bone marrow biopsy/aspiration collection. Efficacy assessments were performed to determine CRi. A treatment cycle was defined as 4 weeks. No statistical analysis was planned for this primary outcome.

    Cmax is the maximum observed plasma concentration after drug administration.The PK parameters were determined in plasma using non-compartmental methods. A PK sample was excluded from analyses if the patient vomited within the first 4 hours following the last oral dose of study drug. Other PK samples were excluded as deemed appropriate by the pharmacokineticist. Cmax was derived from the PK concentrations collected at 0, 0.5, 1, 2, 4, 6, 8 and 24 hours post dose on W1D1 and W9D1. The PK concentration at each time point is not an endpoint in the protocol, but these concentrations are used to derive the PK parameters.
