TCb vs EC-T in High Risk ER+/HER2- Breast Cancer

Recruiting now · Phase 3

Conditions studied: Hormone Receptor Positive HER-2 Negative Breast Cancer

In brief

This study will evaluate the efficacy and safety of docetaxel plus carboplatin (TCb) regimen compared with conventional chemotherapy regimen (epirubicin plus cyclophosphamide followed by docetaxel, EC-T) regimen as adjuvant chemotherapy in patients with early-stage high-risk estrogen receptor (ER) positive and human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer.

Who can join

Age: 18 and older, up to 70. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Women aged 18-70
• Unilateral invasive carcinoma confirmed by histology (regardless of pathological type)
• The initial diagnosis condition can be directly operated, without absolute surgical contraindications
• No gross or microscopic tumor remains after surgical resection
• Adjuvant chemotherapy should be started within eight weeks after surgery
• Patients with Hormone receptor-positive, HER2-negative (HR+HER2-), and positive axillary lymph nodes ≥4
• Definition of ER and Progesterone Receptor (PgR) positive: Positive ER for tumor cells detected by immunohistochemistry is defined as ER positive , and positive PgR for tumor cells detected as PgR positive .
• There was no evidence of metastasis in clinical or imaging aspects during preoperative examination
• No peripheral neuropathy;
• Eastern Oncology Collaborative Group (ECOG) physical status score: 0 or 1
• Good postoperative recovery, at least 1 week interval between surgery
• Adequate hematological and end-organ function as defined by the following laboratory test results, which need to be completed within 28 days prior to the first study treatment: absolute neutrophil count (ANC) ≥ 1500 cells/μL (no granulocyte colony stimulating factor (G-CSF) support therapy within 2 weeks prior to day 1 of course 1); Lymphocyte count≥ 500 cells/μL; Platelet count≥ 100,000 cells/μL (no platelet transfusion within 2 weeks before day 1 of course 1; hemoglobin≥ 9.0 g/dL; Aspartate transferase (AST), Alanine aminotransferase (ALT), and alkaline phosphatase≤ 2.5 × upper limit of normal (ULN) serum total bilirubin ≤ 1.0 × ULN; Patients with known Gilbert disease and serum bilirubin levels ≤ 3× ULN may be admitted; For patients not receiving anticoagulant therapy: INR or activated partial thromboplastin time (APTT) ≤ 1.5 × ULN within 28 days prior to initiation of study therapy; For patients receiving anticoagulant therapy: a stable anticoagulant regimen within 28 days before the start of study therapy and a stable International normalised ratio (INR); creatinine clearance≥ 30 mL/min (calculated using the Cockcroft-Gault formula); Serum albumin ≥ 2.5 g/dL
• For women of childbearing age: agree to remain abstinent (avoid heterosexual intercourse) or take an annual failure rate for at least 5 months during treatment and at least 6 months after the last dose of docetaxel or epirubicin, or 12 months after the last dose of cyclophosphamide, whichever occurs last < 1% of contraception. A woman who is postmenopausal but has not yet reached postmenopausal status (menopause lasts ≥for 12 consecutive months, for no reason other than menopause) and has not undergone sterilization (ovarian and/or hysterectomy) is considered fertile.
• Cardiac function: left ventricular ejection fraction (LVEF) >50% by ultrasound examination
• Sign the Informed Consent Form (ICF)

• For currently diagnosed breast cancer, prior systemic anticancer therapy (eg, neoadjuvant therapy or adjuvant therapy) includes, but is not limited to, chemotherapy, anti-HER2 therapy (eg, trastuzumab emtansine, pertuzumab, lapatinib, neratinib or other tyrosine kinase inhibitors), hormone therapy, or anti-cancer radiotherapy (RT), except for treatments planned under this study condition
• Previous treatment with anthracyclines or taxane for any malignant tumor
• History of ductal carcinoma in situ (DCIS) and/or lobular carcinoma in situ (LCIS), treatment of ipsilateral breast cancer with systemic therapy, hormone therapy, or RT, followed by invasive cancer, patients treated with DCIS/LCIS only surgery and/or RT for contralateral DCIS may be enrolled in the study.
