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   36568   clinical trials with a EudraCT protocol, of which   6041   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Part A
    The primary objective of Part A is to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of CX-2029, by evaluating the overall safety profile and dose-limiting toxicities (DLTs).

    Part B
    The primary objectives of Part B are to:
    • Characterize the protease activity and measure the cleavage of CX-2029 in tumor biopsies and peripheral blood in subjects with histologically or cytologically confirmed metastatic or locally advanced HNSCC, DLBCL, NSCLC, or pancreatic cancer
    • Obtain additional characterization of the safety of CX-2029

    Part C
    The primary objective of Part C is to evaluate the antitumor activity of CX-2029 in expanded cohorts using the MTD/RP2D determined in Part A. Antitumor activity will be assessed on the basis of the ORR as determined by the RECIST v1.1 for solid tumors or the modified Lugano
    Classification for Lymphomas for DLBCL.
    E.2.2Secondary objectives of the trial
    Part A:
    • Evaluate antitumor activity based on:
    - Objective response rate (ORR) by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 or tumor-specific criteria, as applicable
    - Duration of response (DOR)

    • Characterize the pharmacokinetics (PK) of CX-2029 (total and intact) and MMAE (conjugated and unconjugated)
    • Assess the incidence of antidrug antibody (ADA) formation to CX-2029


    Part B:
    • Evaluate the ORR by RECIST v1.1 for solid tumors or the modified Lugano Classification for Lymphomas for DLBCL
    • Characterize the PK of CX-2029 (total and intact) and MMAE (conjugated and unconjugated)
    • Assess the incidence of ADA formation to CX-2029


    Part C:
    • Obtain additional characterization of the safety of CX-2029
    • Evaluate antitumor activity based on:
    - TTR
    - DOR
    - PFS
    - OS
    • Characterize the PK of CX-2029 (total and intact) and MMAE (conjugated and unconjugated)
    • Assess the incidence of ADA formation to CX-2029
