What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 4 studies follow an already-approved treatment in real-world conditions to monitor long-term safety and effectiveness.

This trial targets 1,576 participants in total. It began in 2022-07-10 with a primary completion date of 2027-06-10.

Brief Summary

Due to the unique advantages of albumin-bound paclitaxel, several studies in China and abroad have tried to use albumin-bound paclitaxel for neoadjuvant treatment of breast cancer up to now. However, comparative studies between paclitaxel and docetaxel are still rare, In this study, a prospective, randomized, open-label, multi-center clinical study was conducted to analyse the efficacy and safety of albumin-bound paclitaxel and docetaxel in the neoadjuvant treatment of breast cancer, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.

Eligibility Criteria

Inclusion Criteria: 1. Female patients aged ≥18 years; 2. unilateral primary invasive breast cancer that meets clinical diagnostic criteria and is histologically confirmed; 3. The tumor is \>2cm, and the clinical stage is consistent with cT stage 2-4; or lymph node metastasis with clear clinical/pathological evidence; 4. known hormone receptor status (estrogen receptor \[ER\], progesterone receptor \[PR\]) and HER2 status with known Ki67 expression levels; (ER/PR positive defined as stained cells \>1%, HER2 positive defined as IHC 3+ or IHC 2+ with a positive FISH test); 5. Triple-negative breast cancer (TNBC): ER/PR negative, HER2 negative; tumor \>2cm or lymph node metastasis with clear postoperative pathological evidence; Luminal breast cancer: ER\>1%, HER2 negative, postoperative pathological evidence definite lymph node metastasis (different adjuvant chemotherapy regimens depending on whether the lymph nodes are N1 or N2-3); HER2-positive breast cancer: HER2-positive, regardless of ER/PR status; (the above classification determines enrollment and neoadjuvant therapy, and does not represent the corresponding molecular typing definition); 6. patients who need neoadjuvant chemotherapy as judged by the investigator; 7. ECOG physical fitness score of 0-1; 8. The patient has not received any treatment for breast cancer before enrollment; 9. Electrocardiogram (ECG) and echocardiography must confirm normal cardiac function within 3 months prior to randomization. Left ventricular ejection fraction (LVEF) must be ≥55%; 10. Liver and kidney function: serum creatinine ≤1.5 times the upper limit of normal; AST and ALT ≤3 times the upper limit of normal; total bilirubin ≤1.5 times the upper limit of normal, or ≤2.5 times the upper limit of normal when the patient has Gilbert's syndrome ; 11. Bone marrow function: neutrophils≥1.5×109/L, platelets≥100×109/L, hemoglobin≥90g/L; 12. Able to comply with outpatient treatment, laboratory monitoring and necessary clinical visits during the study period; 13. Subjects have the ability to understand, agree and sign the Informed Consent Form (ICF) for the study prior to initiating any protocol-related procedures; subjects have the ability to express consent (where applicable). Exclusion Criteria: 1. Advanced and/or inoperable patients with distant metastasis confirmed by imaging evidence or pathology; 2. Patients with bilateral invasive breast cancer; 3. Other malignant tumors have occurred in the past 5 years, except for skin cancers of cured cervical carcinoma in situ and non-melanoma; 4. Pregnant or breastfeeding women; patients with childbearing potential who are unwilling or unable to take effective contraceptive measures; 5. The molecular status of ER/PR and HER2 and Ki67 cannot be determined; 6. Patients with CNS metastases or \> grade 1 peripheral neuropathy; 7. Surgical axillary staging within 6 months prior to study entry; 8. Radiotherapy, chemotherapy, biotherapy and/or endocrine therapy for currently diagnosed breast cancer prior to study entry; 9. Patients with severe myelosuppression at screening; 10. Patients with severe liver dysfunction (Child's Class III) or renal dysfunction at screening ; 11. Other concomitant diseases (e.g. untreated congenital heart disease, glomerulonephritis, etc.) which, in the opinion of the investigator, seriously endanger the safety of the patient or would prevent the implementation or completion of the programme treatment; 12. Patients with hypersensitivity to any of the components of albumin paclitaxel, epirubicin, cyclophosphamide, docetaxel, trastuzumab, and pertuzumab; 13. Patients with psychiatric disorders; 14. Subjects who are participating in another clinical study or whose first dose was administered less than 4 weeks (or 5 half-lives of the study drug) from the end of the previous clinical study (last dose) ; 15. The investigator judges other situations that may affect the clinical research and the judgment of the research results and are not suitable for inclusion in the research.
