Phase II Trial of Carboplatin and Bevacizumab for Progressive Breast Cancer Brain Metastases

The purpose of this research study is to determine how well the combination of bevacizumab
and carboplatin works in treating breast cancer that has spread to the brain. Bevacizumab is
an antibody (a protein that attacks a foreign substance in the body) that is made in the
laboratory. Bevacizumab works differently from the way chemotherapy drugs work. Usually
chemotherapy drugs attack fast growing cancer cells in the body. Bevacizumab works to slow or
stop the growth of cells in cancer tumors by decreasing the blood supply to the tumors. When
the blood supply is decreased, the tumors don't get the oxygen and nutrients they need to
grow. Carboplatin is in a class of drugs known as platinum-containing compounds and has been
approved for use in the treatment of ovarian cancer. Information from other research studies
suggests that the combination of bevacizumab with carboplatin may be effective in treating
breast cancer.

This study used a two-stage design to evaluate efficacy bevacizumab and carboplatin based on
Central Nervous System (CNS) response. The null and alternative therapy response rates are 5%
versus 20%. If 1 or more participants assessable in the stage one cohort (n=12 assessable
participants) achieve CNS response then accrual proceeds to stage two (n=25 additional
assessable participants). If at least 4 participants in the final set of 37 assessable
participants achieve CNS response then this regimen would be deemed worthy of further study.
The probability of stopping early is 0.54 if the true CNS response rate is 5% and 0.07 if the
true CNS response rate is 20%. The probability of deeming the treatment worthy of further
study is 0.10 and 0.90 if the true CNS response rate is 5% and 20%, respectively.

Inclusion Criteria:

- Histologically or cytologically confirmed invasive breast cancer, with metastatic
disease. patients without pathologic or cytologic confirmation of metastatic disease
should have unequivocal evidence of metastasis by physical exam or radiologic study

- Measurable disease. Patients must have measurable CNS disease, defined as at least one
parenchymal brain lesion that can be accurately measured in at least one dimension
with longest dimension >/= 10mm by local radiology review

- New or progressive CNS lesions, as assessed by the patient's treating physician

- No increase in corticosteroid dose in the week prior to the baseline brain MRI

- 18 years of age or older

- Life expectancy of greater than 12 weeks

- Eastern Cooperative Oncology Group Performance Score (ECOG PS) performance status 0-2

- Normal organ and marrow function as outlined in the protocol

- Left ventricular ejection fraction >/= 50%, as determined by radionuclide
ventriculography (RVG) or echocardiogram within 60 days prior to initiation of
protocol therapy

- Prior carboplatin is allowed if it was not given in conjunction with bevacizumab

- Prior trastuzumab is allowed

- No prior bevacizumab since diagnosis of CNS metastases or within 6 months prior to
diagnosis of CNS metastases

- Women of child-bearing potential and men must agree to use adequate contraception
prior to study entry and for the duration of study participation

Exclusion Criteria:

- Patients who have had chemotherapy within 14 days prior to entering the study, or
those who have not recovered adequately from adverse events due to agents administered
earlier

- Patients may not receive any concurrent investigational agents while on study

- Patients may not receive any cancer-directed concurrent therapy , such as concurrent
chemotherapy, radiotherapy, or hormonal therapy while on study. Concurrent treatment
with bisphosphonates is allowed

- History of Grade 3 or 4 allergic reactions attributed to compounds of similar or
identical biologic composition to bevacizumab, carboplatin, or trastuzumab

- Known contraindication to MRI with gadolinium contrast, such as cardiac pacemaker,
shrapnel, or ocular foreign body

- Leptomeningeal carcinomatosis as the only site of CNS involvement

- More than 2 seizures over last 4 weeks prior to study entry

- Grade 1 or higher CNS hemorrhage on baseline brain MRI

- History of grade 2 or higher CNS hemorrhage within 12 months of study entry

- Inadequately controlled hypertension

- Prior history of hypertensive crisis or hypertensive encephalopathy

- New York Heart Association (NYHA) Grade II or greater congestive heart failure

- History of myocardial infraction or unstable angina within 6 months prior to day 1

- Significant vascular disease within 6 months prior to day 1

- History of hemoptysis within 1 month prior to day 1

- Evidence of bleeding diathesis or significant coagulopathy

- Current, ongoing treatment with full-dose warfarin or its equivalent

- Use of aspirin (>325 mg/day) within 10 days prior to day 1

- Major surgical procedure, open biopsy, or significant traumatic injury within 28 days
prior to day 1 or anticipation of need for major surgical procedure during the course
of the study.

- Core biopsy or other minor surgical procedure, excluding placement of a vascular
access device, within 7 days prior to day 1

- History of abdominal fistula or gastrointestinal perforation within 6 months prior to
day 1

- Serious, non-healing wound, active ulcer, or untreated bone fracture

- Proteinuria as demonstrated by a urine protein-creatinine ratio >/= 1.0 at screening

- Known hypersensitivity to any component of bevacizumab

- Pregnancy or lactation
