Reporting Groups
  Description
Abraxane (Prior Taxane Therapy) Participants who had received a taxane as part of their adjuvant therapy received Abraxane (ABI-007) at 100 mg/m^2 given intravenously (IV) over 30 minutes weekly for 3 weeks followed by 1 week rest. Therapy continued until disease progression or unacceptable toxicity.
Abraxane (No Prior Taxane Therapy) Participants who had not received a taxane as part of their adjuvant therapy received Abraxane (ABI-007) at 100 mg/m^2 given intravenously (IV) over 30 minutes weekly for 3 weeks followed by 1 week rest. Therapy continued until disease progression or unacceptable toxicity.

Invasive breast cancer stages:

Stage I-cancer cells are breaking through to or invading normal surrounding breast tissue.

Stage IIa-breast tumor about 2cm and involvement of ancillary lymph nodes. Stage IIb-a larger tumor than earlier phases. Stage IIIa-axillary lymph nodes clumping together. Stage IIIb-spread further to the skin, breast bone or chest wall. Stage IIIc-expanded involvement of lymph nodes. Stage IV-cancer that has spread beyond the breast and nearby lymph nodes to other organs of the body.

[2] Eastern Cooperative Oncology Group (ECOG) Performance Status is used to assess the progress of disease in a patient, how the disease affects the daily living abilities of the patient, and determine appropriate treatment and prognosis.
[3] The physician assessed sensory neuropathy using the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE) of "Neurology -- Neuropathy - Sensory". The scale is 0 = normal, 1 = asymptomatic; loss of deep tendon reflexes or paresthesia (including tingling) but not interfering with function, 2 = sensory alteration or paresthesia (including tingling), interfering with activities of daily living (ADL); 3 = Sensory alteration or parasthesia interfering with ADLs; 4 = disabling

1.  Primary:   Percentage of Participants With Objective Confirmed Complete or Partial Overall Response According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0 Based on Investigator and Independent Reviewers   [ Time Frame: Every 8 weeks from study start until disease progression; Up to 61 months ]

Measure Type Primary
Measure Title Percentage of Participants With Objective Confirmed Complete or Partial Overall Response According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0 Based on Investigator and Independent Reviewers
Measure Description

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

Time Frame Every 8 weeks from study start until disease progression; Up to 61 months  
Safety Issue No
