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   43801   clinical trials with a EudraCT protocol, of which   7259   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.4Principal exclusion criteria
    1. Patients with active bleeding during the last 7 days prior to inclusion. Active bleeding is defined as any clinically overt hemorrhage (including radiologically diagnosed bleeding) with ongoing hemoglobin fall or bleeding requiring immediate intervention.
    2. Pregnancy or lactation.
    3. Surgery planned within the 3 next months.
    4. Secondary ITP: ITP associated with lymphoma, chronic lymphocytic leukemia, drug induced or ITP secondary to autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis, antiphospholipid syndrome, common variable immune deficiency, human immunodeficiency virus, or hepatitis C.
    5. Concomitant autoimmune hemolytic anemia.
    6. Known allergy and/or sensitivity or contraindication to daratumumab.
    7. Current active malignancy likely to require chemotherapy or surgical treatment during the study period or within one year after the start of the study treatment.
    8. Patients with history of poor compliance or history of alcohol/drug abuse or excessive alcohol beverage consumption that would interfere with the ability to comply with the study protocol, or current or past psychiatric disease that might interfere with the ability to comply with the study protocol or give informed consent.
    9. Patient unable to attend all the visits planned for the trial.
    10. Positive at screening for hepatitis B virus (HBV) surface and core antibodies unrelated to vaccination:
    - patients with positive HBV surface antigen (HbsAg) are not eligible
    - patients who are HbsAg negative and HBV core antigen antibody positive (HBcAg) will be tested for HBV surface antibody (HBsAb) and HBV DNA. If HBsAb titer is >1000 IU/ml, patients may be enrolled. Monthly HBV DNA monitoring will be required while on treatment and for the 6 months after the last dose of the study drug.
    - patients who are HBcAb positive, HBsAg negative with HBsAb titer <100 IU/ml or negative, are not eligible.
    11. Known chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) <50% of predicted normal. Note that FEV1 testing is required for participants suspected of having COPD.
    12. Known moderate or severe persistent astma within the past 2 years, uncontrolled asthma of any classification.
    13. Patient participating in another clinical trial with an investigational drug.
    E.5 End points
    E.5.1Primary end point(s)
    End points safety run-in
    Safety and tolerability defined as:
    1. Treatment-emergent adverse events/ serious adverse events (TEAEs/SAE) incl. hematological treatment related adverse events.
    2. Incidence of platelet counts decrease during the treatment and up to 2 weeks after the treatment.
    3. Incidence of abnormal changes from baseline in laboratory values per CTCAE criteria V 5.0 (e.g., hematology, chemistry).

    End points main part
    • response after daratumumab treatment defined as:
    o • Cohort 1: proportion of patients who achieve platelet count ≥50x109/L in 2 measurements (taken at least 24 hours apart) during week 12 (after first study drug injection), without having received rescue therapy for the last 4 weeks, nor having had dose increment of TPO-RA or corticosteroids during the study period.
    • Cohort 2: proportion of patients who achieve platelet count ≥50x109/L in 2 measurements (taken at least 24 hours apart) during week 16 after first study drug injection without having received rescue therapy for the last 4 weeks , nor having had dose increment of TPO-RA or corticosteroids during the study period.

    E.5.1.1Timepoint(s) of evaluation of this end point
    Main part: 12 or 16 weeks
    E.5.2Secondary end point(s)
    Secondary end points:
    • DOR defined as the duration of sustained platelet count ≥50x109/L without having received any platelet elevating therapy or having had dose increment of TPO-RA and/or corticosteroids. Duration will not consider the 4 weeks following the last daratumumab injection in the study. . Loss of response is defined as platelet count < 50 x 109/L after achieving response, in 2 consecutive blood samples taken at least 24 hours apart.
    • TTF defined as the time with platelet count ≥50x109/L from 4 weeks after the last daratumumab injection to the first platelet count <30x109/L of two counts taken in two consecutive measurements at least 24 hours apart, or administration of any platelet elevating therapy after achieving response. Date of first platelet count measurement or administration of platelet elevation therapy will be used for the calculation of TTF.

    Exploratory end points:
    • Level of anti-GPIIb/IIIa and Ib antibodies before daratumumab therapy and at study week 24 for all included patients.
    • Analysis of platelet bound antibodies and functional testing of immunocompetent cells in peripheral blood and bone marrow before, during daratumumab therapy and at study week 24 (only peripheral blood). Platelet bound antibodies will also be tested at study week 8 (safety run-in), week 12 (cohort 1), at study week 16 (cohort 2).
