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   44334   clinical trials with a EudraCT protocol, of which   7366   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.2 Objective of the trial
    E.2.1Main objective of the trial
    • To identify the MTD of AT9283 in patients with myelofibrosis
    E.2.2Secondary objectives of the trial
    • To characterise the safety and tolerability of AT9283 in patients with myelofibrosis.
    • To make preliminary observations on the activity of AT9283 in patients with myelofibrosis.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Provision of signed written informed consent.
    • Age 18 years or older.
    • Histological evidence of myelofibrosis from a bone marrow biopsy (either primary or following previous treatment of polycythemia vera or essential thrombocythemia).
    • Patients with intermediate or high risk myelofibrosis (according to Blood Vol 88 No 3 (1996) p1013-1018), who have received prior treatment with at least one therapy which has been discontinued either as a consequence of toxicity or unsatisfactory efficacy.
    • ECOG performance status 0, 1 or 2.
    • Negative serum or urine pregnancy test or evidence of surgical sterility or evidence of post-menopausal status. Post-menopausal status is defined as any of the following: natural menopause with menses >1 year ago; radiation induced oophorectomy with last menses >1 year ago; chemotherapy induced menopause with 1 year interval since last menses.
    E.4Principal exclusion criteria
    • Be pregnant or lactating (women of childbearing potential must have a negative serum or urine pregnancy test within 7 days prior to enrolment). Male and female patients of childbearing potential must use appropriate birth control (abstinence, barrier methods, oral contraceptives and/or intrauterine devices) during the entire duration of the study, or the patient must be surgically sterile (with documentation in the patient’s medical records).
    • Inadequate liver function as demonstrated by serum bilirubin > 2.5 times the upper limits of reference range (ULRR) (unless due to Gilbert’s syndrome) or alanine aminotransferase (ALT) or aspartate aminotransferase (AST) or alkaline phosphatase (ALP) ≥ 2.5 times the ULRR.
    • The presence of a bcr-abl fusion product in bone marrow or peripheral blood.
    • Significant renal impairment defined as serum creatinine > 1.5 ULRR.
    • All previous therapies for myelofibrosis must have been completed at least one month prior to treatment with AT9283 (other than supportive therapies such as antibiotics or blood product transfusions).
    • Prior treatment with a JAK2 inhibitor.
    • Incomplete recovery from surgery or radiotherapy other than stable < Grade 2 toxicity.
    • History of an ischemic cardiac event, myocardial infarction or unstable cardiac disease within 3 months of study entry.
    • Previous malignancy, except for non-basal-cell carcinoma of skin or carcinoma-in-situ of the uterine cervix, unless the tumor was treated with curative intent more than 2 years prior to study entry.
    • Any evidence of severe or uncontrolled systemic conditions (e.g., systemic infection) or current unstable or uncompensated respiratory or cardiac conditions which makes it undesirable for the patient to participate in the study or which could jeopardize compliance with the protocol.
    • Prior history of infection with human immunodeficiency virus (HIV), known active hepatitis B or C viruses – screening for viral infections is not required for entry to this study.
    • Epilepsy or other convulsive disorder requiring active management.
    E.5 End points
    E.5.1Primary end point(s)
    • The appearance of dose limiting toxicities (DLTs). The MTD will be defined by the number of DLTs during Cycle 1 of treatment only, although decisions on dose escalation will also be dependent upon the occurrence of severe toxicities during repeated cycles of treatment.
