Brief Summary:
The clinical efficacy of fulvestrant and/or palbociclib in the population of patients with metastatic lesions harboring ESR1 mutations was reported. In the PALOMA 3 study, the combination of Fulvestrant+ Palbociclib seems to be active in patients whose tumour harbours ESR1 mutations. This study will confirm these data on this population and will allow us to identify if other gene alterations or a genomic signature can correlate with fulvestrant +palbociclib resistance.

Criteria

Inclusion Criteria:

  1. Women 18 years of age or older, who are either:

    • Postmenopausal, as defined by at least one of the following criteria:
    • Age > 60 years;
    • Age <60 years and cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and serum estradiol and Follicle-Stimulating Hormone (FSH) level within the laboratory's reference range for postmenopausal females;
    • Documented bilateral oophorectomy;
    • Medically confirmed ovarian failure.
  2. Histologically or cytologically proven diagnosis of breast cancer with evidence of metastatic or locally advanced disease, not amenable to resection or radiation therapy with curative intent.
  3. Documentation of ER-positive and/or PR-positive tumor (>10% positive stained cells) based on most recent tumor biopsy utilizing an assay consistent with local standards.
  4. Documented HER2-negative tumor based on local testing on most recent tumor biopsy:

    HER2-negative tumor is determined as immunohistochemistry score 0/1+ or negative by in situ hybridization (FISH/CISH/SISH) defined as a HER2/CEP17 ratio <2 or for single probe assessment a HER2 copy number <4.

  5. Patients must satisfy the following criteria for prior therapy:

    • Progressed while on or within 1 month after the end of prior aromatase inhibitor therapy for advanced/metastatic breast cancer if postmenopausal.
    • One previous line of chemotherapy for advanced/metastatic disease is allowed in addition to endocrine therapy as a maintenance therapy.
    • Endocrine therapy required being the most recent treatment.
    • Patients could have been treated by EVEROLIMUS
  6. Except where prohibited by local regulations, all patients must agree to provide and have available a formalin-fixed paraffin embedded (FFPE) tissue biopsy taken at the time of presentation with recurrent or metastatic disease. A frozen de novo tissue biopsy is required at inclusion and at progression in a visceral, skin or lymph node lesion
  7. Patient must have measurable lesions (according to RECIST 1.1)

    • Patients with only osteoblastic bone lesions are not eligible

  8. Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
  9. Patients must be treated by palbociclib+fulvestrant according to their Summary of Product Characteristics (SmPC) described bellow as a reminder :

    Adequate organ and marrow function defined as follows:

    • ANC >1,500/mm3 (1.5 x 109/L);
    • Platelets >100,000/mm3 (100 x 109/L);
    • Hemoglobin > 9 g/dL (90 g/L);
    • Serum creatinine <1.5 x Upper Limit of Normal (ULN) or estimated creatinine clearance >60 ml/min as calculated using the method standard for the institution;
    • Total serum bilirubin <1.5 x ULN (<3 ULN if Gilbert's disease);
    • AST and/or ALT <3 x ULN (<5.0 x ULN if liver metastases present);
    • Alkaline phosphatase <2.5 x ULN (<5 x ULN if bone or liver metastases present).
  10. Resolution of all acute toxic effects of prior therapy or surgical procedures to National Cancer Institute (NCI) CTCAE Grade <1 (except alopecia).

  6. Other severe acute or chronic medical or psychiatric condition, including recent or active suicidal ideation or behavior, or laboratory abnormality that may increase the risk associated with study participation or palbociclib+fulvestrant administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
