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   44157   clinical trials with a EudraCT protocol, of which   7327   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
    The main objectives of the trial are:
    • To determine the safety and tolerability of SFX-01 in combination with Aromatase Inhibitors, tamoxifen and fulvestrant;
    • To determine clinical benefit rate (CBR) (complete response [CR] + partial response [PR] + stable disease [SD]) at 24 weeks using RECIST v1.1.
    Objectif principal :
    • déterminer la sécurité et la tolérance du SFX-01 en association avec un IA, du tamoxifène ou du fulvestrant ;
    • déterminer le taux de bénéfice clinique (TBC) (RC+RP+MS) à 24 semaines à l'aide de RECIST v1.1.
    E.2.2Secondary objectives of the trial
    The secondary objectives of the trial are:
    • To determine objective response rate at 24 weeks using RECIST v1.1;
    • To determine time to response;
    • To determine time to progression (TTP);
    • To determine progression free survival (PFS) at 24 weeks;
    • To determine overall survival (OS) at 24 weeks;
    • To determine clinical benefit by measuring duration of response compared to duration of response to prior Endocrine Therapy;
    • To determine time to next treatment.
    Objectifs secondaires :
    • déterminer le taux de réponse objective (TRO) (RC+RP) à 24 semaines à l'aide de RECIST v1.1 ;
    • déterminer le délai de réponse ;
    • déterminer le délai avant progression (DAP) ;
    • déterminer la survie sans progression (SSP) à 24 semaines ;
    • déterminer la survie globale (SG) à 24 semaines ;
    • déterminer le bénéfice clinique en mesurant la durée de réponse par rapport à la durée de réponse avant l'ET ;
    • déterminer le délai avant un nouveau traitement.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    The principal inclusion criteria are:
    1. Male or female patients 18 years or older (the patient must be within the legal age limit to give informed consent in the jurisdiction the study is taking place in);
    2. Patients with histologically confirmed estrogen receptor positive (ER+) breast cancer. Estrogen receptor is considered positive if a percentage score of ≥10% of tumour cells stain positive for ER.;
    3. Histological confirmation of Human Epidermal Growth Factor Receptor 2 (HER2) negative breast cancer on primary tumour at diagnosis or on biopsy of a metastasis. HER2 negative is defined by the ASCO/CAP guidelines;
    4. Patients with clinical or histological confirmation of metastatic or locally advanced disease not amenable to curative surgical resection;
    5. Patients must have at least 1 site of measurable disease, defined as at least 1 lesion that can be accurately measured in at least 1 dimension (longest diameter to be recorded) ≥10 mm with spiral computed tomography (CT) scan or magnetic resonance imaging (MRI) scan (malignant lymph nodes should be ≥15 mm to be considered measurable); all sites of disease should be noted and followed in accordance with RECIST v1.1. A lytic or mixed lytic-blastic bone lesion with a soft tissue component assessed on CT/MRI can be measurable if the minimum size criteria are met. Blastic bone lesions and bone lesions assessed on bone scan, positron emission therapy (PET) or plain films are nonmeasurable);
    6. Patients must have an anticipated life expectancy of at least 12 weeks;
    7. Adequate bone marrow, renal and hepatic function defined as follows:
    o Haemoglobin > 9 g/dL;
    o Absolute neutrophil count > 1.0 x 109/L;
    o Platelets > 100 x 109/L;
    o Total bilirubin within normal limits, except those with Gilbert’s syndrome for whom this must be <2.5 x ULN;
    o AST(SGOT) or ALT(SGPT) < 2.5 x ULN;
    o Calculated creatinine clearance > 30 ml/min;
    8. Eastern Cooperative Oncology Group (ECOG) performance status < 2;
    9. Must currently be on either a third generation Al, tamoxifen or fulvestrant and have a documented evidence of progressive disease after the following:
    (a) taking endocrine therapy (ET) as adjuvant therapy for >2 years or
    (b) achieving a best response of stable disease (for at least 6 months) or an objective response of complete response (CR) or partial response (PR) on the current treatment, both indicating the development of secondary resistance to current therapy;
    10. Suitable for continuing endocrine therapy according to the treating clinician. The window of discontinuation must not exceed 4 weeks.
    11. All patients (or their legally acceptable representatives) must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
    12. No more than 3 lines of endocrine therapy for metastatic/locally advanced breast cancer including the treatment that the patient is receiving at the time of study entry. This can include targeted agents alongside endocrine therapy such as, but not limited to, everolimus and palbociclib.
