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   44334   clinical trials with a EudraCT protocol, of which   7366   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients with residual invasive disease after neoadjuvant chemotherapy at high risk of recurrence defined by either:
    - For HR-negative: any residual invasive disease > ypT1mi
    - For HR-positive disease: a CPS+EG score ≥ 3 or CPS+EG score 2 and ypN+ using local ER and grade assessed on core biopsies taken before start of neoadjuvant treatment.
    -Patients must have received neoadjuvant taxane-based chemotherapy for 16 weeks (anthracyclines are permitted). This period must include 6 weeks of a taxane containing neoadjuvant chemotherapy (exception: for patients with progressive disease that occurred after at least 6 weeks of taxane-containing neoadjuvant chemotherapy, a total treatment period of less than 16 weeks is also eligible).
    -An interval of less than 16 weeks since the date of final surgery or less than 10 weeks from completing radiotherapy (whichever occurs last) and the date of randomization is required
    -Radiotherapy should be delivered before the start of study treatment. Radiotherapy to the breast is indicated in all patients with breast conserving surgery and to the chest wall and lymph nodes
    according to local guidelines as well as in all patients with cT3/4 or ypN+ disease treated by mastectomy.
    -Immune checkpoint inhibitor / immunotherapy during neoadjuvant therapy is allowed.
    -Germline BRCA1/2 mutated or wildtype/unknown.
    -Willingness and ability to provide archived formalin fixed paraffin embedded tissue (FFPE) block from surgery after neoadjuvant chemotherapy and from core biopsy before start of neoadjuvant
    chemotherapy, which will be used for centralized prospective confirmation of HR status, HER2
    status, Ki-67 and tumor-infiltrating lymphocytes (TILs) and for retrospective exploratory correlation
    between genes, proteins, and mRNAs relevant to sensitivity/resistance to the investigational
    agents. For patients with bilateral carcinoma, FFPE blocks from both sides have to be provided for
    central testing.
    E.4Principal exclusion criteria
    -Patients with definitive clinical or radiologic evidence of stage IV cancer (metastatic disease) are not eligible.
    -Severe and relevant co-morbidity that would interact with the application of cytotoxic agents or the participation in the study, including Gilbert´s disease, Crigler-Najjar-Syndrom, known hepatitis B,
    hepatitis C, known HIV positivity or known autoimmune disease (other than diabetes, vitiligo, or
    stable thyroid disease) and infection requiring intravenous antibiotic use within 1 week of enrolment.
    -Known or suspected congestive heart failure (>NYHA I) and/or coronary heart disease, angina
    pectoris requiring antianginal medication, previous history of myocardial infarction, evidence of
    prior infarction on ECG, uncontrolled or poorly controlled arterial hypertension (i.e. BP >150/90
    mmHg under treatment with at maximum three antihypertensive drugs), rhythm abnormalities
    requiring permanent treatment (excluding chronic atrial fibrillation not requiring a pacemaker),
    clinically significant valvular heart disease, supraventricular and nodal arrhythmias requiring a
    pacemaker or not controlled with medication; conduction abnormality requiring a pacemaker.
    -Known allergic reactions to irinotecan.
    E.5 End points
    E.5.1Primary end point(s)
    iDFS is defined as time from randomization until first iDFS event: local invasive recurrence following mastectomy, local invasive recurrence in the ipsilateral breast following lumpectomy, regional recurrence, distant recurrence, contralateral invasive breast cancer, second non-breast primary cancer (excluding squamous or basal cell carcinoma of the skin), or death from any cause (Hudis JCO 2007).
    E.5.1.1Timepoint(s) of evaluation of this end point
    Interim Analyses for primary endpoint:
    One interim analysis for overwhelming efficacy will be performed in the study. O’Brien – Fleming type stopping boundaries based on the Lan-DeMets spending function will be applied.
    The interim analysis will take place when 256 events (2/3 of the total events) have occurred. It was estimated that the interim analysis will occur 54 months from study start.

    Final iDFS (and interim OS) analysis:Q4 2026
    E.5.2Secondary end point(s)
    -OS is defined as the time from randomization until death from any cause.
    -DDFS is defined as the time from randomization until distant recurrence of disease, second primary invasive cancer (non-breast, excluding squamous or basal cell carcinoma of the skin), and death due to any cause.
    -LRRFI is defined as the time from randomization until any loco-regional (ipsilateral breast (invasive), chest wall, local/regional lymph nodes) recurrence of disease or any invasive contralateral breast cancer whichever occurs first. Distant recurrence, secondary malignancy and death are considered as competing risks and will be accounted for in the analysis.
    -Frequency and severity of adverse events graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
    -Dose-density, dose reductions, dose delays, treatment interruptions and treatment discontinuation rates.
    -Patient reported breast cancer specific QoL as measured by FACT–B; functional assessment of cognitive function assessed by FACT-Cog; patient reported global QoL assessed by EQ-5D-5L.
    E.5.2.1Timepoint(s) of evaluation of this end point
    One interim analysis of OS is planned where O’Brien – Fleming type stopping boundaries based on the Lan-DeMets spending function will be applied.
    The interim analysis will take place at the time of the final analysis of iDFS (75 months after study start). It is expected that approximately 282 events (73% of the total events) have occurred.
    The actual nominal a levels for the interim analysis and for the final analysis of OS will depend on the fraction of total events occurred at the time of interim analysis.
