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 Primary · Every 8 weeks from study start until disease progression; Up to 61 months

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 b

Percentage of Participants With Disease Control Secondary · Every 8 weeks from study start until disease progression; Up to 61 months

Disease control was defined as stable disease (SD) for ≥ 16 weeks or complete response (CR) or partial response (PR). Response was evaluated by the Investigator and by an independent reviewer using Response Evaluation Criteria in Solid Tumors (RECIST) guidelines version 1.0. 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.

Progression-free Survival (PFS) Secondary · Study start until disease progression, death, or up to data cut off of 31 May 2013; up to 61 months

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 who did not have progression or did not die were censored at the last known time the participant was progression free. Participants who initiated other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated.

Duration of response was 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. Participants who did not have progression or had not died were censored at the last known time the participant was progression free. Participants who had initiated other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated. CR and PR were defined in outcome #1.

The number of participants with dose reductions, dose interruptions and dose delays that occurred during the treatment period. Dose reductions, interruptions and delays are typically caused by clinically significant laboratory abnormalities and /or treatment emergent adverse events/toxicities.

Number of Participants With Treatment-Emergent Adverse Events Secondary · Day 1 to Day 940

Count of study participants who had at least one treatment-emergent adverse event (TEAE) defined as any adverse event that began or worsened in grade after the start of study drug through 30 days after the last dose of study drug. The National Cancer Institute (NCI)'s Common Terminology Criteria for AEs (CTCAE) was used to grade AE severity: severity grade 3= severe and undesirable AE. Severity grade 4= life-threatening or disabling AE. Severity grade 5 = death.

Sponsor's own description

The purpose of this study is to determine the toxicity and anti-tumor activity of nab-paclitaxel 100mg/m\^2 administered weekly in a 4-week cycle as first line therapy to patients with metastatic breast cancer who received taxanes as part of their adjuvant therapy and patients who did not receive taxanes as part of their adjuvant therapy.
