About

The investigators hypothesize that the combination of Gemzar®, Abraxane® and Avastin will increase the progression-free survival (PFS) in patients with first line metastatic breast cancer and in patients who received neoadjuvant and/or adjuvant chemotherapy present with definable metastatic disease, 6 or more months after primary treatment.

Full description

This is a phase 2, single arm study. Participants will be treated with combination Gemzar, Abraxane and Avastin therapy until disease progression. Each treatment cycle is 28 days.

Enrollment: 30 patients

Sex: All

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers
