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. 2018-01-26 2019-08-01 Phase II Study of Enzalutamide in Advanced AR-Positive TNBC. power of 85% when the true response rate was 20%. Approximately 95 patients were expected to yield 62 evaluable patients.

2018-07-01 · With DFS data available for 521 TNBC patients, AR-positive tumors had a significant lower risk of relapse compared to the other TNBC subgroups (OR for DFS 0.44, p 0.002) . Finally, an additional meta-analysis by Wang et al. confirmed that women with AR-positive TNBC display a 20% lower risk of recurrence compared with AR-negative TNBC (HR 0.8, p < 0.05).

Coadministered with prednisone, abiraterone is an oral selective inhibitor of 17α‐hydroxylase and C17,20‐lyase that reduces androgen biosynthesis, thus providing a rationale for studying this agent in patients with advanced AR + TNBC. A total of 34 women with AR + TNBC were treated on the phase 2 study of abiraterone in combination with prednisone (ClinicalTrials.gov identifier NCT01842321).

Approximately one-third of TNBC expressed androgen receptor (AR) and evaluation of AR-positive TNBC primary tumors shows nuclear localization of AR, an indication of transcriptionally active receptors. I. To estimate progression free survival (PFS) distribution of androgen receptor (AR)-positive TNBC patients who were nonresponders to initial anthracycline and cyclophosphamide chemotherapy, treated with enzalutamide in combination with weekly paclitaxel in the neoadjuvant setting. II. Triple-negative breast cancer (sometimes abbreviated TNBC) is any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) and HER2/neu. This makes it more difficult to treat since most hormone therapies target one of the three receptors, so triple-negative cancers often require combination therapies. In addition, recent studies reported that anti-androgen therapy shows preclinical efficacy in androgen-receptor (AR)-positive TNBC cells. Here we examined the effect of palbociclib in combination with an anti-androgen enzalutamide in TNBC cells. 2019-03-01 AR-Positive TNBC (N=340) AR-Neg TNBC (QNBC) (N=1612) AR-unknown (N=119) Breast Liver Lymph Nodes Skin Lung Connective Tissue Other Patient Age Average 59.2 54.9 p<0.0001 Interquartile Range 52-68 47-63 Although TNBC lacks hormone receptors traditionally associated with breast cancer, emerging data suggest that AR plays a strong role in the Patients with ER-positive and/or progesterone receptor-positive primary tumors were eligible if they had advanced TNBC.

Here we present a meta-analysis to investigate the correlation between AR expression and TNBC prognosis. Results: Thirteen relevant studies with 2826 TNBC patients were included. AR positive rate was 24.4%. 2018-07-01 2014-08-08 Investigators assessed the outcomes of 118 patients with AR-positive locally advanced or metastatic TNBC who received enzalutamide 160 mg once daily. Examples of these tailored approaches include poly(ADP-ribose) polymerase inhibitors for BRCA-mutated TNBC, antiandrogens for androgen receptor (AR)-positive TNBC, fibroblast growth factor receptor (FGFR) inhibitors for TNBC harboring FGFR amplifications, and gamma-secretase inhibitors for TNBC with mutations in the PEST domain of NOTCH proteins.

Background: Although the androgen receptor (AR) is frequently expressed in breast cancer; tamoxifen; oestrogen receptor; triple-negative breast cancer 

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.

Immunohistochemistry (IHC) was carried out on formalin-fixed AR biomarker discovery Treat to progression AR testing IHC results reported as: “Positive” (AR > 0%) “Negative” (AR = 0%) • AR “positive” TNBC* • ECOG-PS ≤ 1 • Sufficient tissue to enable biomarker discovery • No CNS metastases • Any number of prior therapies permissible • Evaluable bone-only disease allowed Stage 1 In addition, recent studies reported that anti-androgen therapy shows preclinical efficacy in androgen-receptor (AR)-positive TNBC cells.
