Phase 3


Inclusion Criteria:

   - Life expectancy of at least 10 years, excluding their diagnosis of breast cancer.

   - Women who have had breast reconstruction utilizing tissue expanders must be in
   agreement with delaying surgery to replace the tissue expanders with permanent
   implants until 3 months following the last dose of bevacizumab

   - Women of reproductive potential must agree to use an effective non-hormonal method of
   contraception (for example condoms, some intrauterine devices, diaphragms,
   vasectomized partner, or abstinence) during therapy and for at least 6 months after
   the last dose of bevacizumab and/or trastuzumab.

   - Submission of tumor samples from the breast surgery for central HER2 testing is
   required for all patients prior to enrollment in the BETH Trial

   - Signed and dated IRB/EC-approved consent

   - ECOG performance status of 0 or 1

   - The tumor must be unilateral invasive adenocarcinoma of the breast on histologic

   - The breast cancer must be HER2-positive based on test results as follows: Local
   testing (if available) should demonstrate that the tumor is IHC 2+ or 3+ or is
   considered to be HER2-positive for gene amplification by FISH, CISH, or other in situ
   hybridization (ISH) method. If local ISH test results are considered equivocal, the
   tumor can be submitted for central HER2 testing. (If local testing is not possible,
   the tumor can be submitted for central HER2 testing.) Central testing (a requirement
   for ALL patients) must demonstrate that the tumor is HER2-positive which is defined as
   FISH-positive and/or IHC 3+.

   - All of the following staging criteria (according to the 6th edition of the AJCC Cancer
   Staging Manual) must be met: By pathologic evaluation, primary tumor must be pT1-3; By
   pathologic evaluation, ipsilateral nodes must be pN0, pN1 (pN1mi, pN1a, pN1b, pN1c),
   pN2a, pN3a, or pN3b. If pN0, at least one of the following criteria must be met:
   Pathologic tumor size > 2.0 cm; ER negative and PgR negative; Histologic and/or
   nuclear grade 2 (intermediate) or 3 (high); or Age < 35 years

   - Patients must have undergone either a total mastectomy or breast conserving surgery

   - For patients who undergo lumpectomy, the margins of the resected specimen must be
   histologically free of invasive tumor and ductal carcinoma in situ (DCIS) as
   determined by the local pathologist. If pathologic examination demonstrates tumor at
   the line of resection, additional operative procedures may be performed to obtain
   clear margins. If tumor is still present at the resected margin after re-excision(s),
   the patient must undergo total mastectomy to be eligible. (Patients with margins
   positive for lobular carcinoma in situ [LCIS] are eligible without additional

   - For patients who undergo mastectomy, margins must be free of gross residual tumor.
   Patients with microscopic positive margins are eligible.

   - Patients must have completed one of the following procedures for evaluation of
   pathologic nodal status: Sentinel lymphadenectomy followed by removal of additional
   non-sentinel lymph nodes if the sentinel node (SN) is positive; Sentinel
   lymphadenectomy alone if pathologic nodal staging based on sentinel lymphadenectomy is
   pN0, pN1mi or pN1b; or Axillary lymphadenectomy without SN isolation procedure.

   - The interval between the last surgery for breast cancer (treatment or staging) and
   randomization must be at least 28 days but no more than 84 days.

   - Patients must have ER analysis performed on the primary tumor prior to randomization.
   If ER analysis is negative, then PgR analysis must also be performed.

   - The most recent postoperative blood counts, performed within 6 weeks prior to
   randomization, must meet the following criteria: ANC must be greater than or equal to
   1200/mm3; Platelet count must be greater than or equal to 100,000/mm3; and Hemoglobin
   must be greater than or equal to 10 g/dL.

   - The following criteria for evidence of adequate hepatic function must be met based on
   the results of the most recent postoperative tests performed within 6 weeks prior to
   randomization: total bilirubin must be less than or equal to upper limit of normal
   (ULN) for the lab unless the patient has a bilirubin elevation > ULN to 1.5 x ULN due
   to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and
   alkaline phosphatase must be less than or equal to 2.5 x ULN for the lab; and AST must
   be less than or equal to 1.5 x ULN for the lab. Alkaline phosphatase and AST may not
   both be > the ULN.

   - Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the
   study if liver imaging (CT, MRI, PET scan, or PET-CT scan performed within 3 months
   prior to randomization) does not demonstrate metastatic disease and the requirements
   for evidence of adequate hepatic function are met.

   - Patients with alkaline phosphatase that is > ULN but less than or equal to 2.5 x ULN
   are eligible for inclusion in the study if a bone scan,PET scan, or PET-CT scan
   (performed within 3 months prior to randomization) does not demonstrate metastatic

   - The following criteria for renal function must be met based on the results of the most
   recent postoperative tests performed within 6 weeks prior to randomization: Serum
   creatinine must be less than or equal to ULN for the lab. Measured or calculated
   creatinine clearance must be > 60 mL/min.

   - A urine sample must be tested for protein by determination of the urine
   protein/creatinine (UPC) ratio or by urine dipstick. UPC ratio must be less than 1.0.
   Urine dipstick must indicate 0-1+ protein. If dipstick reading is greater than or
   equal to 2+, determine the UPC ratio, which must be less than 1.0, or collect a
   24-hour urine specimen, which must demonstrate < 1.0 g of protein per 24 hours.

   - LVEF assessment must be performed within 3 months prior to randomization. The LVEF
   must be greater than or equal to 55% regardless of the cardiac imaging facility's
   lower limit of normal (LLN).

   - The ECG (performed within 3 months prior to randomization) must not have demonstrated
   any of the following conditions: ventricular arrhythmias except for benign premature
   ventricular contractions; supraventricular and nodal arrhythmias requiring a pacemaker
   or not controlled with medication; and conduction abnormality requiring a pacemaker.
