Trial Information

Randomized Phase II Study of Fulvestrant With or Without Ganetespib in Patients With Hormone Receptor-Positive, Metastatic Breast Cancer

Because no one knows which of the study options is best, you will be "randomized" into one
of the study groups: Arm A: Fulvestrant or Arm B: Fulvestrant plus Ganetespib. You will have
a one-third chance of being placed in Arm A and a two-thirds chance of being placed in Arm

If you are initially placed in Arm A but your disease progresses, you will have the option
of receiving the combination of fulvestrant plus ganetespib as part of Arm C.

You will undergo the following procedures during the research study: study drug(s), blood
tests, clinical exams and scans/imaging tests.

Inclusion Criteria:

- Histologically confirmed invasive breast cancer that is metastatic or unresectable
locally advanced

- Estrogen and/or progesterone receptor positive breast cancer

- HER2 negative

- Measurable or evaluable disease is allowed

- Endocrine resistant breast cancer

- May have received up to one prior line of chemotherapy for metastatic or unresectable
locally advanced breast cancer

- May have initiated bisphosphonate therapy prior to start of protocol therapy

- Must be at least 2 weeks from prior chemotherapy or radiotherapy

- ECOG performance status of 0 or 1

- Availability of tissue block from initial breast cancer diagnosis and/or metastatic

- For subjects with biopsy-accessible disease, must be willing to undergo a required
on-treatment research biopsy

- Adequate IV access

Exclusion Criteria:

- Pregnant or breastfeeding

- Prior treatment with HSP90 inhibitor

- Prior treatment with fulvestrant

- Concurrent treatment with commercial agents or other agents with the intent to treat
the participant's malignancy

- Untreated or progressive brain metastases

- Pending visceral crisis, in the opinion of the treating investigator

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to fulvestrant or ganetespib

- Uncontrolled intercurrent illness

- Other malignancies within 3 years
