Description

Inclusion Criteria:

• Patient has microscopically confirmed invasive breast carcinoma with clinical and/or radiographic evidence of stage 4 disease. If diagnosis is based on pleural effusion, positive cytology must be confirmed.
• Patient has had no prior chemotherapy for Stage 4 disease (hormone therapy is permitted). Prior adjuvant paclitaxel by 3-hour infusion is permitted, if there is no residual neuropathy. Prior adjuvant docetaxel on an every 3 week schedule is permitted.
• Disease must be measurable (unidimensional by Response Evaluation Criteria In Solid Tumors (RECIST) criteria) or evaluable (e.g., malignant effusion, marrow involvement). Elevated tumor markers alone are insufficient.
• Age >18.
• Southwest Oncology Group (SWOG)/Eastern Oncology Group (ECOG) performance status must be < or =2 at screen and on treatment day one.
• Life expectancy must be estimated at >16 weeks.

• Prior irradiation is permitted, provided:

  • Does not exceed 25% of the estimated bone marrow volume
  • Measurable/evaluable disease exists outside the radiation field, or progressive disease is documented within the radiation field.
• Informed consent must be obtained prior to registration.
• Patients must be > 2 weeks from prior surgery; > 3 weeks from radiation therapy to the pelvis, spine or long bones; > 3 weeks from prior chemotherapy (> 6 weeks for mitomycin C or nitrosureas), or > 2 weeks from prior hormonal therapy.
• All patients must have placement of appropriate central venous access device.
• Tumor HER2/neu expression must be determined prior to study enrollment. Assessment may be by fluorescence in situ hybridization (FISH) assay or by immunohistochemistry (ICC). If determination is intermediate by ICC, FISH must be performed. For enrollment purposes, this phase I study will not discriminate based on HER2 status. However, documentation of patients' HER2 status will be maintained and Herceptin will be prescribed for all HER2 positive patients.

Exclusion Criteria:

• Granulocytes < 1,500/mm^3.
• Platelets < 100,000/mm^3.

• Pregnancy or lactation; failure to employ adequate contraception.
• Uncontrolled central nervous system (CNS) disease.
• Pre-existing Grade ≥ 2 peripheral neuropathy except for abnormalities due to cancer.
• Psychological, familial, sociological or geographical conditions which do not permit weekly medical follow-up and compliance with the study protocol.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Participants With Confirmed Complete or Partial Overall Response According to Response Evaluation Criteria in Solid Tumors (RECIST Version 1.0)	Overall response rate (ORR) is complete response (CR) + partial response (PR). Complete response (CR): The disappearance of all known disease and no new sites or disease related symptoms confirmed at least 4 weeks after initial documentation. All sites must be assessed, including non-measurable sites, such as effusions, or markers. Disappearance of all non-target lesions. The normalization of tumor marker level confirmed at least 4 weeks after initial documentation. Partial response (PR): At least a 30% decrease in the sum of the longest diameters of target lesions, taking as a reference the baseline sum of the longest diameters confirmed at least 4 weeks after initial documentation. PR is also recorded when all measurable disease has completely disappeared, but a non-measurable component (i.e., ascites) is still present but not progressing. As well as persistence of one or more non-target lesion(s) and/or the maintenance of tumor marker level above the normal limits.	up to month 30
Participants With Dose Limiting Toxicities	Toxicities were evaluated based on the U.S. National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. Any drug-related toxicities CTC Grade 3 or higher were considered dose limiting. Grade 3=severe AE, Grade 4=life-threatening or disabling AE, Grade 5=death. Other conditions considered dose-limiting toxicities include: requirement of a dose adjustment during the first 4 weeks; a dose delay of >3 weeks during the first 4 weeks Grade 3 or greater toxicities attributed to the use of Herceptin were not considered dose-limiting toxicities. The optimal tolerated dose of ABI-007 and vinorelbine given concurrently was defined as the dose administered in the absence of DLTs.	up to month 1
Percentage of Participants With Discontinued, Delayed or Interrupted Therapy	Percentage of participants who had discontinued therapy or had a delayed dose or an interrupted (omitted) dose due to toxicities/adverse events.	up to week 129
Participant Counts of the Most Severe Grade for Absolute Neutrophil (ANC), White Blood Cell (WBC), Platelet, and Hemoglobin Counts as Graded by the National Cancer Institute Common Terminology Criteria for Adverse Experience (NCI CTCAE v3)	Myelosuppression is a decrease in the ability of the bone marrow to produce blood cells. The lowest measured (nadir) blood counts were graded using NCI CTCAE version 3. ANC: Grade 0 = within normal limits; Grade 1 = < lower limit of normal - 1.5*10^9/L; Grade 2 = <1.5 - 1.0*10^9/L; Grade 3 = <1.0 - 0.5*10^9/L; Grade 4 = <0.5*10^9/L WBC: Grade 0 = within normal limits; Grade 1 = < lower limit of normal - 3.0*10^9/L; Grade 2 = <3.0 - 2.0*10^9/L; Grade 3 = <2.0 - 1.0*10^9/L; Grade 4 = <1.0*10^9/L Platelets: Grade 0 = within normal limits; Grade 1 = < lower limit of normal - 75.0*10^9/L; Grade 2 = <75.0 - 50.0*10^9/L; Grade 3 = <50.0 - 25.0*10^9/L; Grade 4 = <25.0*10^9/L Hemoglobin: Grade 0 = within normal limits; Grade 1 = < lower limit of normal - 100 g/L ; Grade 2 = <100 - 80 g/L; Grade 3 = <80 - 65 g/L; Grade 4 = <65 g/L	up to week 129 (longest treatment)
Nadir Measurement for Absolute Neutrophil (ANC), White Blood Cell (WBC) and Platelet Count	Myelosuppression is a decrease in the ability of the bone marrow to produce blood cells. The lowest observed measurement is the nadir. Blood counts were performed each week of treatment.	up to week 129 (longest treatment)
Nadir Measurement for Hemoglobin (Hgb)	Myelosuppression is a decrease in the ability of the bone marrow to produce blood cells. The lowest observed measurement is the nadir. Blood counts were performed each week of treatment.	up to week 129 (longest treatment)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Stable Disease for >= 16 Weeks, or Complete or Partial Response According to Response Evaluation Criteria in Solid Tumors (RECIST Version 1.0)	Disease control is stable disease (SD) for >=16 weeks + complete response (CR) + partial response (PR). See Outcome #1 for definitions of CR and PR. RECIST defines SD for target lesions as neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, no occurrence of progression disease for non-target lesions, and no new lesions.	up to month 30
Kaplan Meier Estimate for Time to Disease Progression (TTP)	Time to progression was defined as the time from the first dose of study drug to the start of progression. Participants that did not have progression were censored at the last known time the patient was evaluated for progression. Participants that initiate other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated. Progressive disease was defined as at least a 20% increase in the sum of the longest diameters of target lesions; or the appearance of one or more new lesions; or the unequivocal progression of a non-target lesion.	up to month 30
Kaplan-Meier Estimate for Duration of Response	Duration of response is defined as progression-free survival in responders, i.e. as the time between the start of a complete response (CR) or partial response (PR) and the start of progressive disease (PD) or patient death from any cause, whichever occurred first. Patients that did not have progression or have not died were censored at the last known time the patient was progression free. Patients that initiate other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated. Complete response (CR) and partial response (PR) are defined in outcome #1. Progressive disease was defined as at least a 20% increase in the sum of the longest diameters of target lesions; or the appearance of one or more new lesions; or the unequivocal progression of a non-target lesion.	up to month 30
Kaplan Meier Estimate for Progression-Free Survival (PFS)	PFS was defined as the time from the first dose of study drug to the start of progression or patient death (any cause) whichever occurred first. Participants that did not have progression or have not died were censored at the last known time the participant was progression free. Participants that initiate other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated. Because no patients died as a result of a non-disease progression event, the analysis of PFS was identical to the analysis for TTP.	up to month 30
Kaplan-Meier Estimates for Participant Survival	Participant survival is the time from the first dose of study drug to participant death from any cause. Participants that did not die were censored at the last known time the participant was alive.	up to 39 months
