NeoAdjuvant PErsonalized therapy in Estrogen Receptor positive breast cancer (NAPEER) - An open label phase II trial of endocrine treatment with or without capivasertib, followed by response assessment before neoadjuvant chemotherapy with bevacizumab (if ViRP signature positive)
EU CTIS ID: 2023-510093-13-00
What this study is testing
Endocrine therapy: To assess the effect of neoadjuvant capivasertib in combination with letrozole or neoadjuvant letrozole alone in patients with hormone receptor positive HER2 negative breast cancer. Chemotherapy : To assess the efficacy of neoadjuvant chemotherapy with or without bevacizumab in a pre-treatment selected subgroup, using a molecular signature, in patients with large (cT2 – cT4) hormone receptor positive, HER2 negative breast cancer.
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- Capable of giving signed informed consent, which includes commitment to comply with the requirements and restrictions listed in the informed consent form (ICF) and in this clinical study protocol (CSP)
- Women (or men), age 18 – 80 years, diagnosed with palpable, histologically or cytological confirmed, ER positive (≥1%) HER2-negative, breast adenocarcinoma with a measurable disease (>20 mm) on ultrasound imaging.
- The patient should be eligible for neoadjuvant chemotherapy treatment used in the study as evaluated by the treating physician (assisted by gene expression signatures with a result indicating an intermediate or high risk of disease recurrence, or by tumor core biopsy with an Ki67 average labelling index ≥ 20%).
- WHO performance status ≤ 1
- Adequate hematological function with absolute neutrophil count (ANC) ≥1.0 x 109/L AND platelet count ≥100 x 109/L AND hemoglobin ≥9 g/dL (may be transfused to maintain or exceed this level).
- Male patients should use barrier contraception (ie, condoms) from the time of screening until 16 weeks after discontinuation of study drug. It is not known whether the preclinical changes seen in the male animal reproductive organs, after treatment with capivasertib, will be fully reversible or will permanently affect the ability to produce healthy sperm following treatment. Therefore, if male patients may wish to father children in the future they should be advised to arrange for freezing of sperm samples prior to the start of study treatment.
You likely can't join if
- Involvement in the planning and/or conduct of the study (applies to both Investigator and/or staff at the study site).
- Previous allogeneic bone marrow transplant or solid organ transplant.
- Strong inhibitors or inducers of CYP3A4 within 2 weeks prior to the first dose of study treatment (3 weeks for St John’s wort), or drugs that are sensitive to inhibition of CYP3A4 within 1 week prior to the first dose of study treatment. For details, see Appendix (Appendix A).
- History of hypersensitivity to active or inactive excipients of the study drug or drugs with a similar chemical structure or class to study drugs.
- As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, active bleeding diatheses, or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Screening for chronic conditions is not required.
- Evidence of any other disease, renal, neurological or metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that may affect the interpretation of the results, render the patient at high risk from treatment complications or interferes with obtaining informed consent

- Adequate liver function with total bilirubin <1.5 x upper limit of normal (ULN) AND Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) <2.5 x ULN× upper limit of normal (ULN). Patients with confirmed Gilberts syndrome may be included in the study despite elevated bilirubin.
- Adequate renal function with serum creatinine ≤1.5 x ULN and Creatinine clearance (CrCL) >50 mL/min per the Cockcroft-Gault formula (using actual body weight).
- Urine dipstick for proteinuria <2+. Patients discovered to have ≥2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate ≤1 g of protein in 24 hours.
- Female patients of childbearing potential should be willing to use 2 forms of highly reliable methods of contraception from the time of screening until 4 weeks after discontinuing study treatment OR Patients must have evidence of an inability to bear children by fulfilling 1 of the following criteria at screening: - Post-menopausal – defined as aged >50 years and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments – Documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy or bilateral salpingectomy, but not tubal ligation. Women with an intact uterus (unless amenorrhoeic for the last 24 months and postmenopausal levels of FSH, LH and oestradiol) must have a negative serum pregnancy test within 28 days prior to inclusion into the study.
- For patients to be eligible for endocrine treatment with or without capivasertib: ER positive score in ≥50% of the tumor cells
- International normalized ratio (INR) ≤1.5 and APTT (cephotest) ≤1.5 x ULN within 7 days prior to enrolment.
- Pregnant or breast-feeding women are not eligible for the study.
