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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

    b. Diagnostic testing results that confirm HAE-1/HAE-2: C1-INH functional level < 40% normal level. Patients with a functional level of 40% to 50% of normal can be enrolled if their complement factor C4 level is below the lower limit of normal (LLN) or if a known pathogenic mutation in the SERPING1 gene has been demonstrated
    c. At least 1 of the following: age at reported HAE onset ≤ 30 years; a family history consistent with HAE-1/HAE-2; or complement component 1q within the normal range

    a. Experience a minimum of 2 HAE attacks (confirmed by the Investigator) during the Screening Period
    b. Be willing to complete the PRO assessments throughout the study
    Patients must have access to, and the ability to use, ≥ 1 acute medication(s) (e.g., plasma-derived or recombinant C1-INH concentrate or a BK2-receptor antagonist) to treat angioedema attacks
    E.4Principal exclusion criteria
    • Anticipated use of short-term prophylaxis for angioedema attacks for a pre-planned procedure during the Screening, Treatment or Post-Treatment Periods

    • Anticipated change in the use of concurrent androgen prophylaxis used to treat angioedema attacks
    • Participation in a prior ISIS 721744 study
    • Exposure to any of the following medications:
    a. Angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systemic absorption (such as oral contraceptive or hormonal replacement therapy) within 4 weeks prior to Screening
    b. Chronic prophylaxis with Takhzyro, Haegarda, Cinryze or Orladeyo within 5 half-lives prior to Screening (i.e., Takhzyro within 10 weeks prior to Screening, Haegarda/Cinryze within 2 weeks prior to screening, Orladeyo within 3 weeks prior to Screening)

    Screening if single dose received, or within 12 months of Screening if multiple doses received. This exclusion does not apply to vaccines

    • The time-normalized number of moderate or severe Investigator-confirmed HAE attacks (per month) from Week 5 to Week 25 compared to placebo
    • The number of patients with a clinical response defined as a ≥ 50%, ≥ 70%, or ≥ 90% reduction from Baseline (i.e., screening rate) in Investigator-confirmed HAE attack rate between Week 5 to Week 25 compared to placebo
    • Percent of patients who are well-controlled based on the AECT at Week 25
