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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    - To further characterize the rate of SAEs and AESIs of avapritinib.
    E.2.2Secondary objectives of the trial
    Not applicable
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Patient has histologically confirmed metastatic or unresectable GIST as established by entry in a previous avapritinib clinical trial and has been receiving treatment with avapritinib on one of these trials.
    2. Patient continues to receive clinical benefit from avapritinib treatment, as assessed by the investigator.
    3. Patient or legal guardian, if permitted by local regulatory authorities, provides informed consent.

    1. Patient requires therapy with a concomitant medication that is a strong inhibitor or strong inducer of cytochrome P450 (CYP) 3A4.
    2. Patient has a history of intracranial bleeding either prior to or during avapritinib treatment
    3. Patients who have poor organ function, defined as Adverse Events of NCI CTCAE version 5.0 Grade 3 or higher at the time of enrollment must delay start of treatment until symptoms return to Grade 2 or baseline, or the start of treatment has been approved by the Sponsor.
    4. Patients who have ongoing cognitive or mood effects Adverse Events of NCI CTCAE version 5.0 higher than Grade 1 must delay start of treatment until symptoms return to Grade 1 or baseline.
    5. Women who are unwilling, if not postmenopausal or surgically sterile, to abstain from sexual intercourse or employ highly effective contraception from the time of enrollment and for at least 30 days after the last dose of avapritinib.

Females with β-hCG values that are within the range for pregnancy but are not pregnant (false-positives) may be enrolled with written consent of the Sponsor, after pregnancy has been ruled out. Females of non-childbearing potential (postmenopausal for more than 1 year; bilateral tubal ligation; bilateral oophorectomy; hysterectomy) do not require a serum β-hCG test.
