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   42174   clinical trials with a EudraCT protocol, of which   6938   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to compare the overall survival (OS) of participants, treated with imetelstat versus BAT, with intermediate-2 or high-risk Myelofibrosis (MF) whose disease is refractory to JAK-inhibitor treatment.
    E.2.2Secondary objectives of the trial
    to evaluate imetelstat versus BAT with respect to:
    • Symptom response rate at Week 24, defined as the proportion of participants who have ≥ 50% reduction in total symptom score (TSS) at Week 24 from baseline as measured by the Myelofibrosis Symptom Assessment Form (MFSAF) v4.0 e-diary questionnaire
    • Progression-free survival, defined as the time interval from randomization date to the first date of disease progression or death from any cause, whichever occurs first
    • Spleen response rate at Week 24, defined as the proportion of participants who achieve ≥ 35% spleen volume reduction (SVR) at Week 24 from baseline as measured by magnetic resonance imaging (MRI) or computed tomography scan and assessed by Central Radiology Review. Additionally, SVR of ≥ 20% and ≥ 10% at Week 24 will be assessed.
    • Complete remission, partial remission, clinical improvement, spleen response, symptoms response, and anemia response per modified 2013 IWG MRT criteria

    Section 18.6) demonstrated by a symptom score of at least 5 points (on a 0 to 10 scale) on
    at least 1 of the symptoms or a score of 3 or greater on at least 2 of the following
    symptoms: fatigue, night sweats, itchiness, abdominal discomfort, pain under ribs on left
    side, early satiety, and bone pain.

    • platelets ≥ 75 x 109/L (i.e., ≥ 75,000/mm3) independent of platelet transfusion
    8. Biochemical laboratory test values must be within the following limits:

    • Alkaline phosphatase (ALP) ≤ 5 x ULN;
    • Serum creatinine ≤ 2 x ULN;
    • Total bilirubin ≤ 3 x ULN; and direct bilirubin ≤ 2 x ULN (unless due to Gilbert’s syndrome or underlying MF).
    9. Eastern Cooperative Oncology Group Performance Status score of 0, 1, or 2

    13. Any life-threatening illness (e.g., COVID-19), medical condition, or organ system dysfunction which, in the investigator’s opinion, could compromise the participant’s safety, interfere with the imetelstat metabolism, or put the study outcomes at undue risk; if participant has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (e.g., compromise the well- being) or that could prevent, limit, or confound the protocol-specified assessments.
