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   43861   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.3Principal inclusion criteria
    1.Of note, the enrolment of patients will continue until emapalumab is commercially available for a given indication, or until sample size is reached, whichever comes first; thus, US enrolment will be limited to
    treatment-naïve patients. Male and female pHLH patients, from birth up to and including 18 years at diagnosis of HLH.
    2. A molecular diagnosis or familial history consistent with pHLH or fulfilment of HLH-2004 diagnostic criteria, i.e., five of the eight criteria below:
    - Fever
    - Splenomegaly
    - Cytopenias affecting 2 of 3 lineages in the peripheral blood (hemoglobin <90 g/L; platelets <100 x 109/L; neutrophils <1 x 109/L)
    - Hypertriglyceridemia (fasting triglycerides ≥3 mmol/L or ≥265 mg/dL) and/or hypofibrinogenemia (≤1.5 g/L)
    - Hemophagocytosis in bone marrow, spleen or lymph nodes, with no evidence of malignancy
    - Low or absent natural killer (NK)-cell activity
    - Ferritin ≥500 µg/L
    - Soluble CD25 (sCD25, i.e., soluble IL-2 receptor) ≥2400 U/mL.
    3. Presence of active HLH disease as assessed by the treating physician.
    4. Patients having already received conventional HLH therapy must fulfil one of the following criteria as assessed by the treating physician:
    - Having not responded
    - Having not achieved a satisfactory response
    - Having reactivated
    - Showing intolerance to previous conventional treatment of HLH.
    5. Informed consent signed by the patient (as required by local law), or by the patient’s legally authorized representative(s) with the assent of patients who are legally capable of providing it, as applicable.
    6. Having received guidance on contraception for both male and female patients sexually active and having reached puberty.
    Females of child-bearing potential require use of highly effective contraceptive measures (failure rate of less than 1% per year) from Screening until 6 months after receiving last dose of the study drug.
    Males with partner(s) of child-bearing potential must agree to take appropriate precautions (such as sexual abstinence, barrier contraception, vasectomy) to avoid fathering a child from Screening until 6 months after receiving last dose of study drug.
    E.4Principal exclusion criteria
    1. Diagnosis of secondary HLH consequent to a proven rheumatic, metabolic or neoplastic disease.
    2. Active mycobacteria, Histoplasma Capsulatum, Shigella, Salmonella, Campylobacter or Leishmania infections.
    3. Evidence of latent tuberculosis.
    4. Presence of malignancy.
    5.

    6. History of hypersensitivity or allergy to any component of the study regimen (e.g., polysorbate).
    7. Receipt of a bacille Calmette-Guerin (BCG) vaccine within 12 weeks prior to Screening.
