About

This trial provides a unique opportunity in that it combines genomic, proteomic and pharmacogenomic assessments in patients receiving chemotherapy for advanced breast cancer. To date no other trials have analyzed gene and protein expression at the same time points in the same patient, combined with clinical outcome. Similar to previous attempts to predict response based on expression of a single gene or protein, we expect that neither genomic or proteomic profiling alone will be sufficient to optimize therapy. Rather, we expect an iterative process that combines information gleaned from both platforms, modified to avoid toxicity based on pharmacogenomics.

Inclusion criteria

Histologically or cytologically confirmed adenocarcinoma of the breast with measurable locally recurrent, locally advanced (that is not amenable to resection with curative intent), or metastatic disease.
Patients must consent to have a biopsy performed to obtain fresh tissue or be able to identify a FFPE tissue block in which tissue samples can be obtained to complete the testing for this study.
Planned chemotherapy regimen of paclitaxel and Avastin for the treatment of metastatic breast cancer.
Females age > 18 years
Written informed consent and HIPAA authorization for release of personal health information.

Exclusion criteria

Patients must not have had chemotherapy for locally recurrent or metastatic breast cancer.
Hormonal therapy for locally recurrent or metastatic disease must have been discontinued at least 2 weeks prior to study entry.
Patients must not have had adjuvant or neoadjuvant taxane therapy within 12 months prior to study entry.
Breast cancer overexpressing HER-2 (gene amplification by FISH or 3+ overexpression by immunohistochemistry) are not eligible unless they have received prior therapy with Herceptin.
Patients must not have had a major surgical procedure within 4 weeks prior to study entry. (Placement of vascular access device, and breast biopsy, will not be considered major surgery.)
Patients must not have had a minor surgical procedure, placement of an access device, or fine needle aspiration within 7 days of starting protocol therapy.
Patients must not have had radiation within 2 weeks prior to study entry.
Previously radiated area(s) must not be the only site of disease for study entry.
Patients must not have a history of bleeding diathesis or have used anticoagulant therapy within 10 days of study entry. (Low dose anticoagulant therapy to maintain patency of a vascular access device is allowed.)
Patients with a history of deep vein thrombosis or pulmonary embolism are not eligible.
Aspirin usage (> 325 mg/day) or other nonsteroidal anti-inflammatory medications known to inhibit platelet function daily are not allowed within 10 days prior to study entry.
Patients currently using any of the following drugs known to inhibit platelet function are not eligible: dipyridamole (Persantine), ticlopidine (Ticlid), clopidogrel (Plavix) and cilostazol (Pletal).
Patients must not have a history of TIA or CVA within 6 months prior to study entry.
Patients must not have a history or radiologic evidence of CNS metastases including previously treated, resected or asymptomatic brain lesions or leptomeningeal involvement (head CT or MRI must be obtained within 6 weeks prior to study entry).
Patients must not have a non-healing wound or fracture.
Patients must not have a hypersensitivity to paclitaxel or drugs using the vehicle Cremophor, Chinese hamster ovary cell products or other recombinant human antibodies.
Females must not be pregnant or breastfeeding. Females of childbearing potential must use an accepted and effective method of contraception (hormonal or barrier method of birth control; abstinence) while on treatment and for a 3 month period thereafter.
Females of childbearing potential must have a negative pregnancy test within 7 days prior to being registered for protocol therapy. Subjects are considered not of child bearing potential if they are surgically sterile (they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal.
History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to study entry
Urine protein: creatinine (UPC) ratio > 1.0 at baseline or urine protein dipstick > 2+.
