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   43865   clinical trials with a EudraCT protocol, of which   7286   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
    Provide early access and to evaluate the safety of ruxolitinib in patients with PV who were HU resistant or intolerant and who had no other standard treatment options
    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.

    Supplied to the Investigators as 5 mg, 10 mg and 20 mg tablets. Starting dose of ruxolitinib was 10 mg bid. A standardized dosing paradigm was used to determine dose adjustments so that each patient was titrated to their most appropriate dose. The ruxolitinib dose was not to exceed 25 mg bid nor be less than 5 mg once a day unless there was an adverse event that warranted interruption

    End point title
    Change from baseline in Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS)
    End point description
    The MPN-SAF (Appendix 6) was a disease specific questionnaire comprised of 10 items that measures fatigue related to MPN disease and the severity of nine of the most prevalent associated symptoms including: early satiety, abdominal discomfort, inactivity, concentration, night sweats, itching, bone pain, fever and weight loss. There were three recall periods used in this questionnaire, which were 24 hours for fatigue, the past week for symptoms of early satiety, abdominal discomfort, inactivity, concentration, night sweats, itching, bone pain and fever, and the past 6 months for weight loss, Each item was scored on a scale ranging from 0 (no fatigue/absent) to 10 (As bad as you can imagine/worst imaginable). The MPN-SAF TSS was computed as the average of the observed items multiplied by 10 to achieve a 0-to-100 scale. The MPN-SAF TSS thus had a possible score range of 0 to 100.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    11 Mar 2016
    Changes were made to the inclusion criteria: requirement of a treatment history for PV that met the definition of resistance or intolerance to hydroxyurea was removed; confirmed diagnosis of PV according to the revised WHO criteria with resistance or intolerance to hydroxyurea was updated; requirement of palpable spleen was removed which allowed patients without splenomegaly to enter the trial. Hemoglobin parameter was added in the laboratory assessment. This parameter was judged as important to assess safety. The paragraph “Progression of malignancy (including fatal outcomes), if documented by use of appropriate method (for example, as per RECIST criteria for solid tumors or as per Cheson's guidelines for hematological malignancies), should not be reported as a serious adverse event” was removed. The sample size was revised to 500 from 1500.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
