Brief Summary:
This is a prospective, multi-center, open-label, single arm, phase II study with a 2-stage design and Bayesian interim monitoring to investigate the safety and efficacy of BEZ235 in patients with progressive metastatic HR+ HER2- breast cancer who have received at least one prior line of endocrine therapy and two to three prior lines of chemotherapy for metastatic disease. Patients will be stratified into 3 groups according to their PI3K (phosphatidylinositol 3-Kinase) pathway activation status.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: BEZ235 Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants

Primary Purpose: Treatment
Official Title: A Phase II Study of Orally Administered BEZ235 Monotherapy in Patients With Hormone Receptor Positive, HER2 Negative, Metastatic Breast Cancer, With or Without PI3K Activated Pathway

Arm Intervention/treatment
Experimental: BEZ235 Drug: BEZ235

Primary Outcome Measures :
  1. Progression-free survival rate after 16 weeks of treatment [ Time Frame: 16 weeks after the first BEZ235 administration ]

Secondary Outcome Measures :
  1. determine the efficacy of BEZ235 (objective response rate) [ Time Frame: about 6 months ]
  2. evaluate the clinical benefit rate of BEZ235 [ Time Frame: about 6 months ]
  3. evaluate the time to response [ Time Frame: about 6 months ]
  4. evaluate the Progression Free Survival Rate at 16-week & 24-week using the Kaplan-Meier method [ Time Frame: 16-week & 24-week after the first BEZ235 administration ]
  5. evaluate safety of BEZ235 (frequency and severity of Adverse Events, abnormal laboratory values, other safety data as appropriate) [ Time Frame: 30-35 days after treatment discontinuation ]
