A Phase II Neoadjuvant Clinical Trial of the Androgen Receptor Inhibitor Darolutamide in Early-Stage Androgen Receptor Positive (AR+) Triple-Negative Breast Cancer
This phase II trial compares the effect of adding darolutamide to standard therapy versus standard therapy alone before surgery for the treatment of patients with stage II-IIIA androgen receptor positive triple-negative breast carcinoma. Standard therapy before surgery for triple-negative breast cancer typically consists of a combination of chemotherapy and immunotherapy drugs. Chemotherapy drugs, such as carboplatin, paclitaxel, doxorubicin and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Darolutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Giving darolutamide in combination with standard therapy before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed.

Primary outcomes
- Mean ΔKi-67 level — Baseline up to 5 years
The two-sample t-test as well as the Wilcoxon Rank-Sum test will be applied to examine the magnitude of ΔKi-67 between the two study arms. The 95% confidence interval (CI) of the mean difference of ΔKi-67 level between two treatment arms will be reported.
