Abiraterone Acetate in Molecular Apocrine Breast Cancer (AMA)
A Phase II Trial Evaluating the Activity of Abiraterone Acetate Plus Prednisone in Patients With a Molecular Apocrine HER2-negative Locally Advanced or Metastatic Breast Cancer
Study Overview
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 centralized confirmation of ER-/PR-/HER2- and evaluation of AR+ will be included and treated with abiraterone acetate plus prednisone (31 patients).
The Treatment phase comprises a series of 4 weeks-cycles with continuous study treatment. Study drug treatment will continue until the earliest of the following events: disease progression, unacceptable toxicity, or death.
At disease progression, patients must be discontinued from study drug and should be evaluated within 30 days during the Post treatment visit and then entered into the Follow-Up phase.Patients should enter the Follow-Up Period regardless of reason for study drug discontinuation and should be monitored every 3 months (± 7 days) during 2 years.

Genders Eligible for Study
Description
Inclusion Criteria:
- Women aged ≥18 years;
- Histologically confirmed locally advanced or metastatic 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 Criteria:
- 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;

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Clinical benefit rate (CBR)
Time Frame: at 6 months
|
The 6-months CBR is the measurement of all patients who have a complete response (CR), partial response (PR) or stable disease (SD), according to RECIST criteria v1.1.
At six months, patients will be classified as success (Alive at 6 months AND CR/PR/ SD) or failure (dead OR alive with progression).
|
at 6 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Objective response rate (ORR)
Time Frame: at 6 months
|
The Objective response is defined as complete response (CR) or partial response (PR) according to RECIST criteria v1.1
|
at 6 months
|
Duration of overall response (DoR)
Time Frame: at 6 months
|
The DoR is defined as the time from documentation of tumour response (CR/PR whichever is first recorded) to disease progression, according to RECIST criteria v1.1.
|
at 6 months
|
Overall Survival (OS)
Time Frame: median follow-up = 2 years
|
The OS is defined as the time from the first administration of abiraterone acetate to death from any cause.
|
median follow-up = 2 years
|
Progression-free survival (PFS)
Time Frame: median follow-up = 2 years
|
The PFS is defined as the time from the first administration of abiraterone acetate to progression or death of any cause, whichever occurs first.
|
median follow-up = 2 years
|
Overall safety profile
Time Frame: during the on-treatment period (defined as the period from the time of first dose of study medications up to 30 days of the last dose)
|
The overall safety profile of the treatment is determined by the occurrence of adverse events and toxicities.
The severity of the adverse events and toxicities will be graded according the NCI CTCAE scale version 4.0.
|
during the on-treatment period (defined as the period from the time of first dose of study medications up to 30 days of the last dose)
