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   43846   clinical trials with a EudraCT protocol, of which   7282   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare the progression-free survival (PFS) benefit of DS-8201a to physician’s choice in HER2-low, hormone receptor (HR)-positive breast cancer, based on blinded independent central review (BICR).
    E.2.2Secondary objectives of the trial
    • To investigate the efficacy of DS-8201a compared to physician’s choice on the following parameters:
    - PFS in HR-positive subjects, based on Investigator assessment
    - Overall survival (OS) in HR-positive subjects
    - Confirmed objective response rate (ORR), based on BICR and Investigator assessment in HR-positive subjects
    - Duration of response (DoR), based on BICR and Investigator assessment in HR-positive subjects
    - PFS, OS, ORR, and DoR in all subjects, regardless of HR status.
    • To determine pharmacokinetics (PK) of DS-8201a
    • To evaluate safety of DS-8201a compared to physician’s choice of treatment
    • To evaluate Health Economics and Outcomes Research (HEOR) endpoints for DS-8201a compared to physician’s choice
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Men or women ≥18 years old. (Please follow local regulatory requirements if the legal age of consent for study participation is >18 years old.)
    • Pathologically documented breast cancer that:
    - Is unresectable or metastatic.
    - Has a history of low HER2 expression, defined as IHC 2+/ISH- or IHC 1+ (ISH- or untested).
    - Is assessed as low HER2 expression, defined as IHC 2+/ISH- or IHC 1+ according to ASCO-CAP 2018 guidelines (adapted Daiichi Sankyo Inc. and Ventana) evaluated at a central laboratory.
    - Is HR-positive or HR-negative. Approximately 60 HR-negative subjects are to be enrolled; the remaining subjects will be HRpositive.
    - If HR-positive, is documented refractory to endocrine therapy, defined as having progressed on at least 1 endocrine therapy and determined by the Investigator that subject would no longer benefit from further treatment from endocrine therapy.
    - If HR-positive, has or has not been treated with a CDK4/6 inhibitor. Not more than 240 HR-positive subjects who have not had prior therapy with a CDK4/6 inhibitor and at least 240 HR-positive subjects who have had prior therapy with a CDK4/6 inhibitor will be enrolled
    - Has been treated with at least 1 and at most 2 prior lines of chemotherapy in the metastatic setting. If recurrence occurred within 6 months of adjuvant chemotherapy, adjuvant therapy would count as 1 line of chemotherapy.
    - Was never previously HER2-positive (IHC 3+ or ISH+) on prior pathology testing (per ASCO-CAP 2018 guidelines).
    - Was never previously treated with anti-HER2 therapy.
    • Documented radiologic progression (during or after most recent treatment).
    • Must have an adequate archival tumor sample available for assessment of HER2 status by central laboratory (based on
    most recent available tumor tissue sample). If archival tumor tissue is not available, a fresh tumor tissue biopsy is required.
    • All subjects must have a recent tumor sample after the most recent treatment regimen or agree to undergo a tissue biopsy
    prior to randomization.
    • Presence of at least 1 measurable lesion based on computed tomography (CT) or magnetic resonance imaging (MRI), per
    modified Response Evaluation Criteria in Solid Tumors (mRECIST) version 1.1
    • Left ventricular ejection fraction (LVEF) ≥50%
    • Adequate renal function, defined as:
    - Creatinine clearance ≥30 mL/min, as calculated using the Cockcroft-Gault equation
    • Adequate hepatic function, defined as:
