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   39602   clinical trials with a EudraCT protocol, of which   6490   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to compare relapse-free survival (RFS) between subjects with FLT3/ITD AML in first complete remission (CR1) without transplant and who are randomized to receive gilteritinib or placebo beginning after completion of induction/consolidation chemotherapy for a 2-year period.
    E.2.2Secondary objectives of the trial
    Key Secondary Objective:
    ●Compare overall survival (OS) in subjects treated with gilteritinib as maintenance therapy after induction/consolidation with those treated with placebo.
    Additional Secondary Objectives:
    ●Event-free survival (EFS), AEs, clinical laboratory, vital signs, electrocardiograms (ECGs) and Eastern Cooperative Oncology Group (ECOG) performance scores.
    ● Examine the relationship of minimal residual disease (MRD), as determined using a next-generation sequencing (NGS) platform specific to FLT3/ITD mutations, with RFS and OS.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Retrospective Pharmacogenomics Substudy (Optional)
    The PGx research that may be conducted in the future with acquired blood samples and/or buccal swab is exploratory. The objective of this research will be to analyze or determine genes of relevance to clinical response, pharmacokinetics, and toxicity/safety issues. By analyzing genetic variations, it may be possible to predict an individual subject’s response to treatment in terms of efficacy and/or toxicity.

    Pharmacokinetic sampling substudy:
    Sparse (predose) pharmacokinetic samples will be collected in all subjects.
    Additional ECGs and/or time-matched plasma samples will be collected in a subset of approximately 90 subjects (targeting approximately 60 subjects in the gilteritinib arm and 30 subjects in the placebo arm) at the following visits and time points:
    ● Day 15 – 4 hours (± 1 hour) postdose
    ● Day 29 – 4 hours (± 1 hour) postdose
    E.3Principal inclusion criteria
    1. Written informed consent must be obtained from the subject or legally authorized representative prior to any study-related procedures (including withdrawal of prohibited medication, if applicable).
    2. Subject is considered an adult according to local regulation at the time of signing informed consent form (ICF).
    3. Subject consents to allow access to his or her diagnostic bone marrow aspirate or peripheral blood sample and/or the DNA derived from that sample, if available, that may be used to validate a companion diagnostic test for gilteritinib.
    4. Subject has confirmed morphologically documented AML, excluding acute promyelocytic leukemia (APL), in CR1 (including CRp and CRi). For the purposes of enrollment, CR will be defined as < 5% blasts in the bone marrow with no morphologic characteristics of acute leukemia (e.g., Auer rods) in the bone marrow with no evidence of extramedullary disease such as central nervous system involvement or granulocytic sarcoma.
    5. Subject will not proceed with transplantation as either a decision not to proceed with transplantation has been made either on the recommendation of the treating physician or by the patient or a suitable donor could not be identified.
    6. Subject is < 2 months from the start of the last cycle of consolidation and should have completed the recommended number of consolidations per local practice.
    7. Subject has had no use of investigational agents, with the exception of FLT3 inhibiting agents during induction and/or consolidation therapy, within the prior 4 weeks.
    8. Subject has had presence of the FLT3/ITD activating mutation in the bone marrow or peripheral blood as determined by the local institution at diagnosis.
    9. Subject has an ECOG performance status 0 to 2.
    10. Subject must meet the following criteria as indicated on the clinical laboratory tests:
    ● Serum creatinine ≤ 1.5 x institutional upper limit of normal (ULN), or if serum creatinine outside normal range, then glomerular filtration rate (GFR) > 40 mL/min/1.73m2 as calculated with the 4-parameter Modification of Diet in Renal Disease (MDRD) equation.
    ● Serum total bilirubin ≤ 2.5 mg/dL, except for subjects with Gilbert’s syndrome.
    ● Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 x ULN.
    ● Serum potassium and serum magnesium ≥ institutional lower limit of normal (LLN).
    ● Absolute neutrophil count (ANC) ≥ 500/μl and platelets ≥ 20000/μl (unsupported by transfusions).
