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   39363   clinical trials with a EudraCT protocol, of which   6448   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.

    • To further evaluate safety of trastuzumab deruxtecan compared to T
    DM1;
    • To evaluate Health Economic and Outcomes Research (HEOR)
    endpoints for trastuzumab deruxtecan compared to T-DM1.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Adults ≥18 years old. (Please follow local regulatory requirements if the legal age of consent for study participation is >18 y old.)
    • Pathologically documented breast cancer that:
    - is unresectable or metastatic
    - has confirmed HER2 positive expression as determined according to American Society of Clinical Oncology – College of American Pathologists guidelines evaluated at a central laboratory.
    - was previously treated with trastuzumab and taxane in the advanced/metastatic setting or progressed within 6 mo after neoadjuvant or adjuvant treatment involving a regimen including trastuzumab and taxane.
    • Documented radiologic progression (during or after most recent treatment or within 6 mo after completing adjuvant therapy).
    • Subjects must be HER2 positive as confirmed by central laboratory assessment of most recent tumor tissue sample available.
    • Female subjects of reproductive/childbearing potential must agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study and for at least 7 mo after the last dose of trastuzumab deruxtecan and 7 mo after the last dose of T-DM1. Male subjects must agree to inform all potential female partners that they are participating in a clinical trial of a drug that may cause birth defects. Male subjects must also agree to either avoid intercourse or that they and/or any female partners of reproductive/childbearing potential will use a highly effective form of contraception during and upon completion of the study and for at least 4.5 mo after the last dose of
    trastuzumab deruxtecan or 4 mo after the last dose of T-DM1.
    • Adequate renal function, defined as:
    - Creatinine clearance ≥ 30 mL/min, as calculated using the Cockcroft-Gault equation
    • Adequate hepatic function, defined as:
    - Total bilirubin ≤ 1.5 × upper limit of normal (ULN) if no liver metastases or < 3 × ULN in the presence of documented Gilbert's Syndrome (unconjugated hyperbilirubinemia) or liver metastases at baseline

    • Spinal cord compression or clinically active central nervous system (CNS) metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms.
    - Subjects with clinically inactive brain metastases may be included in the study.
    - Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with corticosteroids or anticonvulsants may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 2 weeks must have elapsed between the end of whole brain radiotherapy and study enrollment.
    • Prior participation in a study involving an antibody drug conjugate
    (ADC) produced by Daiichi Sankyo.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is PFS as determined by blinded independent central review (BICR).
    E.5.1.1Timepoint(s) of evaluation of this end point
    An interim and a final analysis for PFS is planned in this trial. The interim
    analysis will be performed when approximately 234 BICR-assessed PFS
    events (70% information fraction) have been observed. If the trial is not
    statistically significant at this interim analysis, the final PFS analysis will
    be performed after observing 335 BICR-assessed PFS events.
    E.5.2Secondary end point(s)
    The key secondary efficacy endpoint is OS.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Two interim analyses and a final analysis of OS are planned. The first OS
    interim analysis is planned at time of the PFS interim analysis, and the
    second OS interim analysis is planned at time of the final PFS analysis.
    Approximately 96 and 153 of the planned 250 OS events (38.4% and
    61.2% of information fractions) will be expected to be documented by
    time of the first and the second OS interim analyses, respectively. Final
    OS analysis is planned after approximately 250 OS events have been
    documented.
