Brief Summary:
This study is aim to evaluate the efficacy and safety of bicalutamide and aromatase inhibitor in ER(+)/AR(+)/HER2(-) metastatic breast cancer patients who have disease progression after treatment of an aromatase inhibitor.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Bicalutamide Drug: Aromatase Inhibitor Phase 2

Detailed Description:
Androgen receptor(AR) is closely related to molecular type, treatment and prognosis in breast cancer. Over 70% of breast cancer expressed androgen receptor. And in some estrogen receptor positive breast cancer cells which are resistant to Aromatase inhibitors can change androgen receptor dependent. So AR may be a new target in the treatment of breast cancer. Bicalutamide is a selective androgen receptor inhibitor with a clinical benefit rate of 19% and median progression free survival of 12 weeks in the ER-/AR+ metastatic breast cancer. This study is aim to evaluate the efficacy and safety of bicalutamide and aromatase inhibitor in ER+/AR+/HER- metastatic breast cancer patients who have disease progression after treatment of an AI.

Arm Intervention/treatment
Experimental: bicalutamide+ Aromatase Inhibitor
ER(+)/AR(+)/HER2(+) metastatic breast cancer patients that previously treated by an aromatase inhibitor
Drug: Bicalutamide
50mg once a day orally
Other Name: Casodex

Drug: Aromatase Inhibitor
participants will receive any kind of aromatase inhibitor which has not been received before (steroidal AI change to nonsteroidal AI and vice versa), Letrozole 2.5mg once a day orally, Anastrozole 1mg once a day orally, Exemestane 25mg once a day orally
Other Names:
  • letrozole
  • anastrozole
  • exemestane

Primary Outcome Measures :
  1. clinical benefit rate(CBR) [ Time Frame: 24 weeks ]
    Response and progression will be evaluated using RECIST 1.1. Evaluation will occur every 2 months for the first 6 months and then every 3 months till progression or termination of the study.CBR is defined as ratio of participants who have stable disease for over 24 weeks.

Secondary Outcome Measures :
  1. progression free survival [ Time Frame: baseline up to approximately 6 months ]
    Time from to the first documentation of objective tumor progression or to death due to any cause.

  2. objective response rate of bicalutamide plus another AI in participants with measurable disease [ Time Frame: 24 weeks ]
    objective response rate includes complete response, partial response.

  3. tolerability of bicalutamide plus an Aromatase inhibitor [ Time Frame: 2 years ]
    evaluate and quality of life of the participants using Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) .
