Albumin-Bound Paclitaxel Combined With Carboplatin as Neoadjuvant Chemotherapy in Luminal B/HER-2 Negative Breast Cancer

Study Overview
=================
Brief Summary
-----------------
This is an open-label, single arm, two-stage Simon Design study for women with LuminalB/HER-2 Negative Breast Cancer treated with Nanoparticle Albumin-Bound Paclitaxel and Carboplatin. The primary objective of the trial is to evaluate of the efficacy and safety of Nanoparticle Albumin-Bound Paclitaxel Combined with Carboplatin as Neoadjuvant Chemotherapy in Luminal B/HER-2 Negative Breast Cancer. The primary endpoint of the study is to assess Pathological complete response rate（pCR）using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1). The total number of patients to be included in this study is 78 patients. The duration of the study, from first patient visit to last patient visit will be approximately 12 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary endpoint is pathological complete remission (pCR) | Histopathological examination of breast and axillary lymph node specimens without invasive cancer cell remnants. Complete pathological response is also considered to be achieved if only in situ cancer cell remnants are present in the surgical specimens. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective response rate (ORR) | The second endpoint ORR composed of tumor response classifications of complete response (CR) and partial response (PR), refers to the number of cases with complete and partial response after treatment as a percentage of the total number of evaluable cases. | 3 months | 
| Breast conserving surgery (BCS) rate | Percentage of patients undergoing breast-conserving surgery after neoadjuvant therapy as a whole evaluable. | 3 months | 
| Adverse events (AE) | Adverse events (AE) were monitored on an ongoing basis and classified according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.03. Patients were assessed for toxicities before each administration, and toxicity was graded accordingly. | 3 months |
