A Phase II Study of Adjuvant Gemcitabine/Capecitabine and Bevacizumab for Patients Treated Neoadjuvantly Chemotherapy for Early Stage Breast Cancer With High Risk for Relapse

For patients with locally advanced breast cancers (LABC) primary or neoadjuvant chemotherapy
(NAC) has become accepted as standard treatment. Advantages of NAC include shrinking the
primary tumor, often rendering an unresectable cancer resectable, and the theoretically
concurrent treatment of occult metastatic disease prior to definitive local therapy (surgery
+/- radiation therapy). NAC can reduce the extent of surgery required for the management of
local breast cancer from mastectomy to lump- or segmentectomy, without compromising major
outcome measures, such as overall and disease free survival. At this time, the current
standard of care for women felt to be candidates for NAC is an anthracycline + taxane
regimen. The intent is to induce a pCR which as noted above is a strong indicator of
survival. Yet, in both large NSABP studies, the proportion of women achieving this is less
than 20% with these regimens raising a major challenge in clinical practice: what is the
appropriate treatment for women with persistent disease after NAC? Given that gemcitabine
and capecitabine are non-cross-resistant to anthracyclines and taxanes and use a different
mechanism of action, have an acceptable toxicity profile, and in the absence of standard
options for therapy we are interested in utilizing these agents coupled with bevacizumab as
adjuvant treatment in women with residual breast cancer following primary chemotherapy.

Inclusion Criteria:

General health

- Women Age >18.

- ECOG Performance status 0-1

- Life expectancy must be 3 months. Clinical stage

clinical examination, breast imaging, and/or preoperative work-up.

- Evidence of residual invasive breast cancer or node positive disease following
neoadjuvant chemotherapy.

Prior Therapy

- Patients must have received primary (neoadjuvant) chemotherapy for local or
locoregional breast cancer containing an anthracycline and a taxane.

- Patients must have completed definitive resection of primary tumor with adequate
excision of gross disease.

- Current use of anti-coagulants is allowed as long as patients have been on a stable
dose for more than 2 weeks with stable INR.

- Chronic therapy with full dose aspirin up to 325 mg/day or standard non-steroidal
anti-inflammatory agents is allowed.

Informed consent

- Provision of signed informed consent.

Exclusion Criteria:

Prior therapy

- No prior gemcitabine, continuous infusion 5-FU, or oral fluoropyrimidine
(capecitabine, UFT, S-1, 5-FU/eniluracil, etc.)

- No known hypersensitivity to capecitabine or prior unanticipated severe reaction to
(capecitabine, UFT, S-1, 5-FU/eniluracil, etc.) therapy or known hypersensitivity

child-bearing potential.

- Nonpregnant and nonlactating.

- Women of child-bearing potential must have a negative serum pregnancy test and must
agree to an effective means of contraception during the entire study period.

Concurrent medical conditions:

- No other active cancers, except non-melanoma skin cancers.

- No serious infection or other serious underlying medical condition that would
otherwise impair their ability to receive protocol treatment.

- Patients with clinically significant medical or psychiatric problems which may
interfere with treatment on study.

Avastin-specific exclusions:

should undergo a 24 hour

- urine collection and must demonstrate ≤ 1g of protein in 24 hours to be eligible).

- Known hypersensitivity to any component of bevacizumab any history of stroke or
transient ischemic attack at any time
