Brief Summary
The purpose of this study is to estimate antitumour activity of abiraterone acetate in Patients with a Molecular Apocrine HER2-negative locally advanced or metastatic Breast Cancer.
Detailed Description
Screening : All women 18+, with a confirmed locally advanced or metastatic Triple Negative Breast Cancer (TNBC), will be screened and invited to participate (300-500 patients). Only patients with a c...
Eligibility Criteria
Inclusion
- Women aged ≥18 years;
- Histologically confirmed locally advanced or metastatic breast cancer;
- Triple negative breast cancer:
- Estrogen receptor (ER)-negative and Progesterone receptor (PR)-negative, as defined by a \<10 % tumour stained cells by immunohistochemistry (IHC); HER2 negative status (i.e. IHC score 0 or 1+, or IHC score 2+ and FISH/SISH/CISH negative), confirmed centrally before inclusion with FFPE tissue from either primary or metastatic breast cancer site\*;
- Androgen receptor (AR)-positive, as defined centrally by a ≥10% tumour stained cells by IHC (AR assessment by local pathologist before inclusion is not mandatory);
- Patients could be chemotherapy naïve (provided they are not presenting with life-threatening metastasis) or have received any number of previous lines of chemotherapy (providing their life expectancy is ≥3 months);
- Pre and post menopausal patients are eligible.
- Measurable or non measurable disease according to RECIST v1.1 criteria;
- PS (ECOG) ≤2;
- Normal haematological function: ANC ≥1,500/mm3; platelets count ≥100,000/mm3; haemoglobin \>10 g/dl;
- Normal hepatic function: total bilirubin ≤1.5 upper normal limit (UNL); ASAT and ALAT ≤2.5 UNL (≤5 UNL in the presence of liver metastases);
- Creatinine clearance (MDRD formula) ≥50 mL/min OR creatinine ≤1.5 times ULN;
- Normal kalemia (serum potassium ≥3.5 mM), natremia and magnesemia;
- Systolic blood pressure (BP) \<160 mm Hg and diastolic BP \<95 mm Hg, as documented on inclusion day (Hypertension at baseline assessment allowed provided it is currently controlled under anti-hypertensive drugs);
- Cardiac ejection fraction ≥50% measured by MUGA or ECHO done within 4 weeks before inclusion;
- If receiving a bisphosphonate or denosumab, dose must have been stable for at least 2 doses before inclusion;
- Patient agreeing to use effective contraception during and for ≥ 6 months after completion of study treatment;
- Patient able to comply with the protocol;
- Patient must have signed a written informed consent form prior to any study specific procedures;
- Patient must be affiliated to a Social Health Insurance.
Exclusion
- Male breast cancer;
- HER2-positive status (positivity defined as IHC3+ and/or FISH amplification \>2.2);
- Other concurrent malignancies, except adequately treated cone-biopsied in situ carcinoma of the cervix or basal cell or squamous cell carcinoma of the skin; patients who have undergone potentially curative therapy for a prior malignancy are eligible provided there is no evidence of disease for ≥ 5 years and patient is deemed to be at low risk for recurrence;
- Active brain metastases or leptomeningeal disease; History of brain metastases allowed provided lesions are stable for at least 3 months as documented by head CT scan or MRI of the brain;
- Non-malignant systemic disease, including active infection or concurrent serious illness that would make the patient a high medical risk;
- Significant cardiovascular disease, including any of the following:
- NYHA class III-IV congestive heart failure;
- Unstable angina pectoris or myocardial infarction within the past 6 months;
- Severe valvular heart disease;
- Ventricular arrhythmia requiring treatment.
- Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not be included;
- Patients with known allergies, hypersensitivity or intolerance to abiraterone acetate, prednisone, or their excipients;
- Persistent toxicities ≥ grade 2 from any cause, except chemotherapy-induced alopecia and Grade 2 peripheral neuropathy;
- Active or uncontrolled autoimmune disease requiring concurrent corticosteroid therapy;
- Any gastrointestinal disorder interfering with absorption of the study drug;
- Difficulties with swallowing study capsules;
- Prior anticancer therapy, including radiotherapy, endocrine therapy, immunotherapy, chemotherapy (CT) within the last 3 weeks (2 weeks for oral or weekly CT ; 6 weeks for nitrosoureas and mitomycin C), or other investigational agents ; Concurrent palliative radiotherapy allowed;
- Concurrent enrolment in another clinical trial in which investigational therapies are administered;
- Pregnant women, women who are likely to become pregnant or are breast-feeding;
- Patients with any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial;
- Patients with history of non compliance to medical regimens or unwilling or unable to comply with the protocol;
- Individual deprived of liberty or placed under the authority of a tutor.
