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   41470   clinical trials with a EudraCT protocol, of which   6815   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) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    The primary objectives of Part A2 are to:
    •Characterize the protease activity and measure the cleavage of CX-2009 in tumor biopsies and peripheral blood in subjects with demonstrated high tumor expression of CD166 by immunohistochemistry (IHC); and
    •Obtain additional characterization of the safety of CX-2009 when administered as monotherapy at dose levels evaluated in Part A.

    The primary objective of Part B is to evaluate the efficacy of CX-2009 when administered IV as monotherapy at the MTD/RP2D (as defined in consideration of available data from Part A and Part A2) in subjects with selected advanced or recurrent solid tumors.
    E.2.2Secondary objectives of the trial
    Evaluate preliminary efficacy in subjects treated with CX-2009 as monotherapy;
    Characterize the pharmacokinetics (PK) of CX-2009;
    Assess the incidence of anti-drug antibody (ADA) formation to CX-2009;
    Obtain additional characterization of the safety of CX-2009 at the MTD/RP2D;
    Evaluate efficacy in subjects treated with CX-2009 as monotherapy.
