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 ).

    Recruitment
    Recruitment details
    		 Participants in the global study were enrolled at 72 clinical centers in 15 countries. In addition, the China-specific extension study enrolled participants with myeloproliferative neoplasm (MPN)-associated myelofibrosis and severe anemia not receiving red blood cell (RBC)-transfusions at 5 sites in China.

    Pre-assignment
    Screening details
    		 Participants in the global study were randomized 2:1 to receive blinded pomalidomide or placebo. All participants in the China extension received open-label pomalidomide. Randomization was stratified by age (≤vs >65 years), white blood cells (< or ≥25 × 10⁹/L), and baseline transfusion requirement (≤vs >4 units RBC/28 days over the prior 84 days).

    		 Change From Baseline in EuroQoL-5D (EQ-5D) Health Index Score [14]
    End point description
    The EQ-5D is a general preference-based health-related quality of life (QoL) instrument to assess health outcomes asking patients to rate their perceived health state today on the following dimensions: mobility, selfcare, usual activities, pain/discomfort, and anxiety/depression. The EQ-5D domains are scored on a Likert-type scale with scores ranging from 1-3, with 1 associated with "no problems," 2 associated with "some problems," and 3 associated with "extreme problems." The EQ-5D Health Utility Index (HUI) will be generated from scores of the five health state domains, and is scored between -0.594 (worst) and 1 (best) imaginable health state, with -0.594 representing an "unconscious" health state.

    		 Change From Baseline in Functional Assessment of Cancer Therapy-Anemia (FACT-An) Total Score [17]
    End point description
    The FACT-An is a 47-item, cancer-specific questionnaire consisting of a core 27-item general questionnaire measuring the four general domains of QoL (physical, social/family, emotional and functional well-being), and an additional 20-item anemia questionnaire (FACT-An Anemia subscale) that measures 13 fatigue-associated items (FACT-F Fatigue subscale) and seven non-fatigue-related items. Each item is scored using a 5-point Likert rating scale (0 = Not at all; 1 = A little bit; 2 = Somewhat; 3 = Quite a bit; and 4 = Very much). FACT-An total score is calculated by adding all the FACT-An subscales together. The total score ranges from 0-188 with higher scores representing better QOL.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    29 Sep 2010
    Significant changes included: - The concept of Clinical Benefit was introduced to enable subjects with a 50% decrease in RBC-transfusion frequency to continue receiving study-medication even if RBC-transfusion independence was not achieved. This applied to subjects achieving RBC-transfusion independence if RBC transfusion independence ended due to an unrelated event. - Blood sampling was done in a subset of subjects to explore the pharmacokinetics of pomalidomide in this population. - RBC transfusions used to determine eligibility required a pre RBC-transfusion hemoglobin level ≤ 90 g/L. In subjects where a hemoglobin level < 90 g/L is dangerous, entry into the study with pre RBC-transfusion hemoglobin level > 90 g/L was allowed as long as a 6-month RBC-transfusion history was available to confirm eligibility. - If a subject could not be randomized within 28 days of signing Informed Consent due to logistical reasons, the medical monitor could approve randomization as soon as possible thereafter to eliminate the need to repeat screening procedures when not otherwise necessary. - A hemoglobin level measured > 72 hours before a RBC-transfusion could be used to determine eligibility if there were no intervening RBC-transfusions. - The medical monitor could approve the inclusion of a subject based on a bone marrow biopsy done > 6 months pre-screening. - In North America and the European Union a unit of RBC is approximately 240 mL and the average weight of a 50-year-old male is 90 kg. The protocol definition of ≥ 2 U RBC/28 days is equivalent to 5 mL/kg/28 days. In Japan and China a unit of RBCs is about 125 mL and the average weight of a 50-year-old male is 60 kg. The equivalent RBC-transfusion dose is 2.5 U/28 days. - Subjects receiving anti-coagulants other than low-dose aspirin were not excluded - Criteria for determination of blastic transformation based on blasts in blood was clarified. - 5-year follow-up for collection of new cancers was added
