Inclusion Criteria:

1. Be 18 years or older and female.

2. Have histologically or cytologically confirmed diagnosis of invasive adenocarcinoma
originating in the breast.

3. Have at least one target lesion per RECIST criteria

4. If the patient has received adjuvant or neoadjuvant taxane therapy, the patient must
not have relapsed with breast cancer within one year of completing this therapy.

5. Have received prior chemotherapy in the adjuvant or metastatic setting with an
anthracycline unless contraindicated.

6. Have no other malignancy within the past five years, except non-melanoma skin cancer,
cervical intraepithelial neoplasia (CIN), or in-situ cervical cancer (CIS).

7. Have the following hematology levels at Baseline:

- ANC greater than or equal to 1,500 x 106 cells/L;

- Platelets greater than or equal to 100 x 109 cells/L;

- Hgb greater than or equal to 90 g/L.

8. Have the following chemistry levels at Baseline:

- AST (SGOT), ALT (SGPT) less than or equal to 2.5 x ULN if no evidence of liver

- AST (SGOT), ALT (SGPT) less than or equal to 5 x ULN if liver metastases are

- Total bilirubin less than or equal to 26 micromol/L (1.5 mg/dL);

- Creatinine less than or equal to 177 micromol/L (2 mg/dL); or 24-hour

- Alkaline phosphatase less than or equal to 5 x ULN (unless bone metastasis is
present in the absence of liver metastasis).

9. Have a life expectancy of greater than or equal to 12 weeks.

10. Have an ECOG Performance status of 0-2.

11. Patients of child-bearing potential must agree to use acceptable contraceptive
methods (e.g., double barrier) during treatment.

12. Patient or legal representative must understand the investigational nature of this
study and sign an Independent Ethics Committee -approved written informed consent
form prior to receiving any study related procedure.

Exclusion Criteria:

1. Patient has radiographic evidence of active (symptomatic, untreated) intraparenchymal
brain metastases; any leptomeningeal metastases; or asymptomatic untreated
intraparenchymal brain metastases requiring treatment.

2. Patient has received more than 1 prior treatment with a non-taxane agent in the
metastatic setting.

3. The only evidence of metastasis is lytic or blastic bone metastases or pleural
effusion or ascites.

4. Patient has a known infection with human immunodeficiency virus or active viral

5. Patient has active heart disease including myocardial infarction or congestive heart
failure within the previous 6 months, symptomatic coronary artery disease, or
uncontrolled arrhythmias.

6. Any condition which in the Investigator's opinion deems the patient an unsuitable
candidate to receive study drug (e.g., uncontrolled bleeding or bleeding diathesis).

7. Any active infection requiring parenteral or oral antibiotics.

8. The patient receives treatment with any:

- Hormonal or other non-investigational agent therapy within 2 weeks prior to
first dose of study drug;

- Herceptin, mitomycin, or nitrosoureas therapy within 6 weeks prior to first

- Chemotherapy (except for palliative bisphosphonate therapy for bone pain which
can be administered as clinically indicated) within 4 weeks prior to first dose
study drug;

- Investigational drug or immunotherapy within 4 weeks prior to first dose study

- Concurrent radiation therapy (except for palliative radiotherapy for

- Radiation therapy within 4 weeks prior to first dose of study drug.

9. Patient has pre-existing peripheral neuropathy of NCI-CTCAE Grade >1.

10. Patient has received paclitaxel, docetaxel, or Abraxane because of metastatic

11. Known hypersensitivity to paclitaxel, Cremophor EL, or liposomes.

12. Pregnant or nursing female patients.

13. Unwilling or unable to follow protocol requirements.

Type of Study:


Study Design:

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Assessment of Overall Response Rate (ORR) following treatment of LEP-ETU at 275 mg/m2 dose

Disease status and tumor response/progression will be assessed based on the Response Evaluation Criteria in Solid Tumor (RECIST) after 2, 4 and 6 cycle. Patient will be followed for overall survival until death.
