Patient demographics and clinical characteristics were consistent between the ITT population and evaluable subgroup. 2014-02-01 2018-01-31 The luminal androgen receptor (LAR) subtype of TNBC is characterized by chemoresistance, yet a lower risk of disease recurrence. 67 It was hypothesized the AR inhibition would result in antitumor activity in this subtype of TNBC, a principle that was proved in the TBCRC001 phase II trial of bicalutamide in which 26 patients with AR positive, ER negative metastatic breast cancer had a 19% Growing studies demonstrated that Androgen Receptor (AR) has an oncogenic role for the patients with AR-positive Triple Negative Breast Cancer (TNBC). AR antagonists in therapy, such as bicalutamide, completely binds to the AR, increasing AR degradation, thus are investigated for the efficacy of the treatment of patients with AR-positive TNBC in the study. 2019-02-22 2017-10-10 Further, AR inhibitors have demonstrated antitumor activity in preclinical and early clinical studies. Traina and colleagues evaluated the safety and antitumor activity of the AR inhibitor enzalutamide in a single-arm, open-label, phase II trial of 118 patients with locally advanced or metastatic AR-positive TNBC.

However, the mechanistic action of AR and the degree to which primary and metastatic tumors depend on AR, both before and after conventional treatment, remain to be defined. We discuss preclinical and clinical data for AR+ TNBC, the difficulties in
As a greater understanding of triple-negative breast cancer (TNBC) heterogeneity develops over time, combinations of PD-1/PD-L1 plus PARP inhibitors, androgen receptor (AR) targeted agents, and PI3K/AKT/mTOR pathway inhibitors are undergoing evaluation by investigators in the field. “We’ve learned that triple-negative breast cancer has multiple different subtypes,” Kari B. Wisinski, MD, said during a presentation at the 22nd Annual Lynn Sage Breast Cancer Symposium, a virtual event. 1

Keywords Androgen receptor; Triple negative breast Aug 22, 2017 Keywords: androgen receptor, triple negative breast cancer, prognostic and low Ki-67 (P=0.007) are more likely to have positive AR. Sep 20, 2017 Unlike hormone receptor-positive subtypes, treatment of TNBC is currently limited by the lack of clinically available targeted therapies.

Growing studies demonstrated that Androgen Receptor (AR) has an oncogenic role for the patients with AR-positive Triple Negative Breast Cancer (TNBC). AR antagonists in therapy, such as bicalutamide, completely binds to the AR, increasing AR degradation, thus are investigated for the efficacy of the treatment of patients with AR-positive TNBC in the study.
power of 85% when the true response rate was 20%. Approximately 95 patients were expected to yield 62 evaluable patients. Estimates of median progression-free survival (PFS) and OS, definedintheAppendix(online only),weredetermined using … 2018-05-09 Evidence suggests that 10% to 35% of all patients with TNBC have AR-positive gene expression.
