Neoadjuvant Darolutamide Alone or in Combination With Standard Therapy for Stage II-IIIA, AR+, TNBC

Recruiting now · Phase 2

Conditions studied: Anatomic Stage II Breast Cancer AJCC v8, Anatomic Stage IIIA Breast Cancer AJCC v8, Triple-Negative Breast Carcinoma

In brief

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.

You may not qualify if…

• Non-resectable breast cancer as assessed by the primary treating surgeon or evidence of metastatic disease

History of cerebrovascular accident (including transient ischemic attack [TIA]) within the past six months (24 weeks) prior to starting study treatment
