I-SPY 2 Trial (Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging And moLecular Analysis 2)

I-SPY 2 will compare the efficacy of novel drugs in combination with standard chemotherapy with the efficacy of standard therapy alone. The goal is identify improved treatment regimens for subsets on the basis of molecular characteristics (biomarker signatures) of their disease. As described for previous adaptive trials, regimens that show a high Bayesian predictive probability of being more effective than standard therapy will graduate from the trial with their corresponding biomarker signature(s). Regimens will be dropped if they show a low probability of improved efficacy with any biomarker signature. New drugs will enter as those that have undergone testing complete their evaluation.

Inclusion Criteria:

• Histologically confirmed invasive cancer of the breast
• Clinically or radiologically measureable disease in the breast after diagnostic biopsy, defined as longest diameter greater than or equal to 25 mm (2.5cm)

• Age ≥18 years
• ECOG performance status 0-1
• Willing to undergo core biopsy of the primary breast lesion to assess baseline biomarkers
• Non-pregnant and non-lactating
• No ferromagnetic prostheses. Patients who have metallic surgical implants that are not compatible with an MRI machine are not eligible.
• Ability to understand and willingness to sign a written informed consent (I-SPY TRIAL Screening Consent)
• Eligible tumors must meet one of the following criteria: Stage II or III, or T4, any N, M0, including clinical or pathologic inflammatory cancer or Regional Stage IV, where supraclavicular lymph nodes are the only sites metastasis
• Any tumor ER/PgR status, any HER-2/neu status as measured by local hospital pathology laboratory and meets any tumor assay profile described in protocol section 4.1.2F

• No uncontrolled or severe cardiac disease. Baseline ejection fraction (by nuclear imaging or echocardiography) must by ≥ 50>#/li###
• No clinical or imaging evidence of distant metastases by PA and Lateral CXR, Radionuclide Bone scan, and LFTs including total bilirubin, ALT, AST, and alkaline phosphatase
• Tumor assay profile must include on of the following: MammaPrint High, any ER status, any HER2 status, or MammaPrint Low, ER negative (<5%), any HER2 status, or MammaPrint Low, ER positive, HER2/neu positive by any one of the three methods used (IHC, FISH, TargetPrint™)
• Ability to understand and willingness to sign a written informed consent document (I-SPY 2 TRIAL Consent #2)

Exclusion Criteria:

• Use of any other investigational agents within 30 days of starting study treatment
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to the study agent or accompanying supportive medications.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
