NCT ID:
NCT06607757
Eligibility Criteria:
Inclusion Criteria:
1. Written informed consent prior to beginning specific protocol procedures, including expected cooperation of the patients for the treatment and followup, and documented according to the local regulatory requirements.
2. Postmenopausal women with age at diagnosis ≥ 18 years.
Postmenopausal status is defined as:
* Age ≥60 years
* Age \<60 years and amenorrhea for at least 12 continuous months with no identified cause other than menopause
* Bilateral oophorectomy Negative pregnancy test (urine or serum) within 14 days prior to randomization for all postmenopausal women 50 years of age or younger without bilateral oophorectomy
3. Unilateral or bilateral primary untreated lobular invasive carcinoma of the breast. In case of bilateral breast cancer, both sides must be lobular; the lead tumor has to be defined by the investigator based on the inclusion criteria for the respective subtype and the risk status. Lobular histology has to be centrally confirmed.
4. Willingness and ability to provide archived formalin fixed paraffin embedded (FFPE) tissue block from core biopsy before the start of neoadjuvant therapy.
5. Centrally confirmed HER2-negative (IHC score 0-1+ or ISH negative according to ASCO/CAP guideline) and HR-positive (≥10% positive stained cells) disease, assessed on the core of diagnostic biopsy. Ki67% \>10% is required. In case of bilateral breast cancer, HER2-negative, HR-positive and lobular histology status has to be confirmed for both sides.
6. Patients with invasive lobular breast cancer at high risk for recurrence defined as cT1c and clinical nodal involvement (cN+) or ≥ cT2 disease (irrespective of nodal involvement).
7. No clinical evidence of distant metastases.
8. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1.
9. Estimated life expectancy of at least 5 years irrespective of the diagnosis of breast cancer.
10. The patient must be accessible for scheduled visits, treatment, and followup.
11. Normal cardiac function must be confirmed according to local guidelines.
12. Laboratory requirements:
Hematology
* Absolute neutrophil count (ANC) ≥1.5 x 109 / L
* Platelets ≥100 x 109 / L
* Hemoglobin ≥10 g/dL (≥6.2 mmol/L) Hepatic function
* Total bilirubin \<1.25x ULN
* AST and ALT \<=1.5x ULN
* Alkaline phosphatase \<=2.5x ULN Glucose Metabolism
* HbA1c \<8.0% (63.9 mmol/mol) Renal Function
* Creatinine \<1.25x ULN or creatinine clearance ≥50 ml/min (if creatinine is above ULN according to Cockroft-Gault)
13. Complete staging work-up prior to the initiation of neoadjuvant therapy as per standard recommendations.
Exclusion Criteria:
1. Female patients of childbearing potential.
2. Excisional biopsy or lumpectomy performed prior to study entry.
3. Surgical axillary staging procedure including sentinel lymph node biopsy prior to randomization. Exceptions: FNA or core biopsy of an axillary lymph node.
4. Any previous treatment including endocrine therapy, chemotherapy, radiotherapy or targeted therapy (including AKT inhibitor or PIK3 inhibitor) for the currently diagnosed breast cancer.
5. Concurrent use of herbal or natural products intended as treatment or prophylaxis for any type of cancer.
6. Known hypersensitivity reaction to one of the compounds or substances used in this protocol.
7. Potent inhibitors or inducers of CYP3A4 within 2 weeks prior to the first dose of study treatment (3 weeks for St John's wort).
8. Refractory nausea and vomiting, chronic gastrointestinal disease, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption, distribution, metabolism, or excretion of capivasertib.
9. Any contraindication for fulvestrant.
10. Patients with definitive clinical or radiologic evidence of stage IV cancer (metastatic disease) are not eligible.
11. Patients with a history of any malignancy are ineligible with the following exceptions:
* Patient has been disease-free for at least 5 years and is at low risk for recurrence of that malignancy except for breast cancer.
* CIS of the cervix, basal cell and squamous cell carcinomas of the skin.
12. History of type I or type II diabetes mellitus requiring insulin.
13. Severe and relevant co-morbidity that would interact with the application of study drugs or the participation in the study, including cerebrovascular incident including transient ischemic attack, or symptomatic pulmonary embolism, active infection requiring intravenous anti-microbial treatment (antibiotics, anti-fungal, and anti-viral drugs) within 1 week of enrolment. Patients with confirmed Gilbert's syndrome may be included in the study.
14. Known medically history of HIV infection, tuberculosis, or hepatitis B.
15. History of and/or active cardiac disease that would preclude the use of study treatments. This includes but is not confined to any of the following cardiac criteria:
* Clinically significant cardiac dysfunction including heart failure (NYHA II-IV), active ventricular arrhythmias requiring medication or arrhythmias requiring a pacemaker, and history of a myocardial infarction within 6 months prior to randomization, angina pectoris, atrial fibrillation of any grade, coronary/peripheral artery bypass graft, angioplasty, or vascular stent.
* Mean resting QT interval corrected by Fridericia's formula (QTcF) \>470 msec obtained from 3 consecutive ECGs.
* Increased risk of QTc prolongation or risk of arrhythmic events such as heart failure, uncontrolled electrolyte disorders (e.g., hypocalcemia, hypokalemia, or hypomagnesemia), potential for torsades de pointes, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age, or any concomitant medication known to prolong the QT interval.
16. Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days of receiving therapy.
17. History of significant neurological or psychiatric disorders including psychotic disorders, dementia, or seizures that would prohibit the understanding and giving of informed consent.
18. Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results (such as severe or uncontrolled systemic diseases, including uncontrolled hypertension or hypotension (BP \<50mmHg), significant aneurysm, renal transplant and active bleeding diseases).
19. Major surgical procedure (excluding placement of vascular access) or significant traumatic injury within 4 weeks of the first dose of study intervention or an anticipated need for major surgery during the study.
20. Participation in another clinical study with a study intervention or investigational medicinal device administered in the 4 weeks prior to first dose of study intervention or concurrent enrolment in another clinical study unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
