Outcome Measures

Primary Outcome Measures :
  1. Clinical Benefit Rate [ Time Frame: ≥ 16 weeks ]
    To determine clinical benefit rate, defined as the proportion of evaluable patients with androgen receptor positive (AR+), triple negative breast cancer (TNBC) with a best response of complete response (CR), partial response (PR), or stable disease (SD) ≥ 16 weeks.

Secondary Outcome Measures :
  1. Clinical Benefit Rate [ Time Frame: ≥ 24 weeks ]
    To determine clinical benefit rate, defined as the proportion of evaluable patients with a best response of Complete Response, Partial Response, or Stable Disease ≥ 24 weeks;

  2. Best Objective Response Rate [ Time Frame: ≥ 16 weeks ]
  3. Duration of Response [ Time Frame: ≥ 16 weeks ]
  4. Time to Response [ Time Frame: ≥ 16 weeks ]
  5. Progression Free Survival (PFS) [ Time Frame: ≥ 16 weeks ]
  6. Pharmacokinetics - Ctrough (predose plasma concentration) [ Time Frame: ≥ 16 weeks ]
    To assess the pharmacokinetics (PK) of enzalutamide and its active metabolite N desmethyl enzalutamide

Other Outcome Measures:
  1. Overall Survival (OS) [ Time Frame: ≥ 16 weeks ]
  2. Androgen Receptor Expression [ Time Frame: ≥ 16 weeks ]
    To determine the extent of androgen receptor (AR) expression and signaling in breast tissue and to evaluate the relationship of this expression with enzalutamide effects on circulating tumor biomarkers, circulating hormones, and clinical outcomes.
