Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42572   clinical trials with a EudraCT protocol, of which   7010   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.5 End points
    E.5.1Primary end point(s)
    Phase 1: The incidence of adverse events, defined as dose-limiting toxicities.

    Phase 2: The objective response rate (complete response [CR] + partial response [PR]) per the Lugano Response Criteria for Malignant Lymphoma, as determined by independent central radiology review.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Phase 1:
    The dose-limiting toxicity (DLT) evaluation period will begin with CTX110 infusion and last for 28 days. If a DLT-evaluable subject has signs or symptoms of a potential DLT, the DLT evaluation period will be extended according to the protocol-defined window to allow for improvement or resolution before a DLT is declared.

    Phase 2:
    - The interim analysis for futility will occur when 30 subjects have been enrolled and have 3 months of evaluable tumor response data.
    - The primary analysis of efficacy will occur after 77 subjects in the modified intention-to-treat (mITT) set have had the opportunity to be assessed for response 3 months after CTX110 infusion.
    - A final analysis will occur when all subjects complete or withdraw from the study.
    E.5.2Secondary end point(s)
    • Duration of response (central read).
    • Progression-free survival (central read).
    • Overall survival.

    • Incidence and severity of adverse events and clinically significant laboratory abnormalities.
