Measure
Fulvestrant + Everolimus
Fulvestrant + Everolimus Fulvestrant was administered intramuscularly (in the gluteus maximus) in a loading dose schedule as follows: 500 mg in two divided doses-one on each side on day 1, then 250 mg on day 14, and then 250 mg on day 28 and every 4 weeks ± 3 days thereafter. Everolimus was administered initially at a dose of 5 mg daily in the first 5-patient cohort for the first month of treatment and then increased to 10 mg PO daily after that.

Time to Progression
7.4 months
Interval 1.9 to 12.1

SECONDARY outcome

Timeframe: Evaluated 60 days after therapy start

Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
