Purpose
The purpose of this study is to evaluate the efficacy and safety of treatment with imetelstat + paclitaxel (with or without bevacizumab) versus paclitaxel (with or without bevacizumab) alone for patients with locally recurrent or metastatic breast cancer who have not received chemotherapy or have received one non-taxane based chemotherapy for metastatic breast cancer.

Primary Outcome Measures:
- Progression-free survival [ Time Frame: Occurring post randomization through end of study period (9 mos. after the last participant is randomized) ]Defined as the time from randomization to documented disease progression, as determined by the investigator's assessment according to RECIST, or death from any cause, whichever occurs first.
Secondary Outcome Measures:
- Objective response [ Time Frame: Occurring post randomization through end of study period (9 mos. after the last participant is randomized) ]Objective response as determined by the investigator according to RECIST for patients with measurable disease at baseline.
- Clinical benefit rate [ Time Frame: Occurring post randomization through end of study period (9 mos. after the last participant is randomized) ]Clinical response rate includes patients with objective response and stable disease lasting at least 6 months.

- Prior use of bevacizumab is allowed provided that it was not administered in combination with a taxane
- ECOG performance status 0-1
-
Adequate bone marrow reserve as indicated by:
- ANC > 1500/uL (without use of growth factors within 7 days)
- Platelet count > 100,000 (without transfusion in prior 7 days)
- Hemoglobin > 9.0 g/dL
Exclusion Criteria:
- Women who are pregnant or breast feeding

- Investigational therapy within 4 weeks of first study drug administration
- Prior radiation, cytotoxic, or hormonal therapy within 2 weeks of first study drug administration
- Therapeutic anti-coagulation or regular use of anti-platelet therapy within 2 weeks prior to first study drug administration (low dose anti-coagulant therapy to maintain patency of a vascular access device is allowed)
