简要总结
ONAWA is a window of opportunity, prospective, multicenter, phase 0 trial which evaluates the effect of onapristone (ONA) on proliferation after 3 weeks of treatment in postmenopausal women with ER+/PgR+ and HER2-negative early breast cancer amenable to pre-operative endocrine therapy and surgery.
详细描述
The main hypothesis is that onapristone, an antiprogestin will induce a significant proliferative arrest in HR+/HER2-negative breast cancer. The primary endpoint is chosen based on reports which related the 2.7% Ki67 value (natural log of 1) both after a 15 days1 or 3-4 months of neoadjuvant endocrine treatment with favorable breast cancer relapse free and overall survival2,3. Hence, this Ki67 cut-off (Complete Cell Cycle Arrest, or CCCA) has been consistently used in recent trials as an acceptable surrogate marker of clinical and biological efficacy, even though the achievement of a pathological complete response is very unusual in luminal tumors after preoperative endocrine therapy. Trials with biological endpoint, including the so-called window of opportunity trials such as the ONAWA study provide tumor tissue before and after a short course of a given therapy for biomarker analyses of response and resistance. The aim of these studies is to improve the investigator's understanding regarding the biologic effect of a given drug, in order to better define its target population early in its development without interfering with the standard treatment pattern of the patient.

入选标准
- •Written and signed informed consent for all study procedures according to local regulatory requirements prior to beginning specific protocol procedures.
- •Age ≥ 18 years.
- •Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or
- •Postmenopausal women defined either by:
- •Age < 60 and amenorrhea for ≥ 12 months and FSH and E2 plasmatic levels in the post-menopausal range per local standards or
- •Prior bilateral oophorectomy (28 days before Day 1 of the study treatment).
- •Histologically confirmed invasive breast carcinoma eligible for surgery with all the following characteristics:
- •Primary tumor diameter of at least 15 mm (cT1c-3) as measured by ultrasound (US).
- •No regional lymph node metastases by imaging or clinical examination (cN0).
- •ER-positive and PgR-positivity (ER+/PgR+), as assessed locally, defined by American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) clinical practice guidelines.
- •HER2-negative status, as assessed locally, defined by American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP)
- •In case of multifocal tumors (defined as the presence of two or more foci of cancer within the same breast quadrant), the largest lesion must be measured in at least one dimension of minimal 15 mm per US. This lesion will be designated as 'target' lesion for all subsequent evaluations. ER+/PgR+ and HER2-negative status must be documented in all the tumor foci. Site markers should be placed in each accessible lesion, even if mastectomy is planned, to facilitate correct tumor assessment by the pathologist.
- •Cells staining positive for Ki67 ≥ 15% as locally assessed.
- •Available pre-treatment formalin-fixed paraffin-embedded (FFPE) tumor specimen or possibility to obtain one. Minimal sample requirements are: at least 2 tumor cylinders with a minimal tissue surface of 10 mm2, containing ≥10% tumor cells, enough to obtain at least 2 cuts of 10 µm each. Tumor cylinder will be mandatory.
- •No clinical or radiographic evidence of distant metastases (M0).
- •Adequate hematologic and organ function within 14 days before the first study treatment on Day 1, defined by the following:
- •Neutrophils (ANC ≥1500/μL).
- •Hemoglobin ≥9 g/dL (with no need for transfusions).
- •Platelet count ≥100000/μL.
- •Serum albumin ≥3 g/dL.
- •Calculated creatinine clearance of ≥ 60 mL/min based on the Cockcroft-Gault glomerular filtration rate estimation:
- •(140 - age) x (weight in kg) x 0.85 72 x (serum creatinine in mg/dL).
- •International normalized ratio (INR) or prothrombin time (PT) ≤1.5 × ULN and activated partial thromboplastin time (aPTT) within therapeutic range.
- •Potassium, total Calcium (corrected for serum albumin), Magnesium and Natrium with institutional normal limits or corrected with normal limits with supplement before first dose of study medication.
- •Ability to swallow study drug and comply with study requirements.
- •Absence of 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.
排除标准

- •Metastatic (Stage IV) breast cancer.
- •Invasive bilateral o multicentric breast cancer.
- •Patients requiring neoadjuvant chemotherapy or immediate surgical intervention.
- •Patients who have undergone sentinel lymph node biopsy or tumor excisional biopsy prior to study treatment.
- •Prior malignancy within 3 years prior to randomization, except curatively treated non-melanoma skin cancer, in situ cervical cancer or adequately treated Stage I or II cancer from which the patient is currently in complete remission or other cancer from which the patient has been disease-free for 2 years.
- •Congenital long QT syndrome or screening QT interval corrected using Fridericia's formula (QTcF) > 480 milliseconds or any clinically significant cardiac rhythm abnormalities.
- •Liver function tests documented within the screening period and on Day 1 of treatment period:
- •d. Total bilirubin >1.5x the upper limit of normal (ULN) unless the patient has documented non-malignant disease (e.g. Gilbert´s syndrome) for whom conjugated bilirubin must be under ULN.
