Clinical Trial Summary

explore the efficacy and safety of the combination of nintedanib and paclitaxel in the neoadjuvant treatment of HER2 positive early or locally advanced breast cancer

Description:

This study is a prospective, open-label, single-arm clinical study, and it is planned to include 20 treatment-naive patients with HER2-positive early or locally advanced breast cancer (clinical stage IIA ~ IIIC). Neoadjuvant treatment regimen was nituximab + pyrrolidine + nab-paclitaxel. To explore the efficacy and safety of the combination of nintedanib and paclitaxel in the neoadjuvant treatment of HER2 positive early or locally advanced breast cancer

2. inflammatory breast cancer;

3. Previous anti-tumor therapy or radiotherapy for any malignant tumor, excluding cured cervical carcinoma in situ, basal cell carcinoma or squamous cell carcinoma and other malignant tumors;

4. concurrent anti-tumor therapy in other clinical trials, including endocrine therapy, bisphosphonate therapy or immunotherapy;

5. Patients who have undergone major surgical procedures unrelated to breast cancer before enrollment, or have not fully recovered from such surgical procedures;
