Progression-free Survival (PFS) as Determined by the Investigator Using Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Baseline to the data cut-off date of 31 Jul 2008 (up to 2 years, 7 months) ] [ Designated as safety issue: No ]
PFS was defined as the time from randomization to first documented disease progression (PD) as determined by the investigator using Response Evaluation Criteria in Solid Tumors (RECIST) or death due to any cause, whichever occurred first. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions. Target lesions should be selected on the basis of their size (those with the longest diameter) and their suitability for accurate repeated measurements by imaging techniques or clinically. All measurable lesions up to a maximum of 5 lesions per organ and 10 lesions in total, representative of all involved organs, should be identified as target lesions.
To determine the clinical benefit, as measured by PFS, of the addition of bevacizumab to chemotherapy treatment compared with chemotherapy alone, in subjects who are receiving first-line therapy for locally advanced or metastatic breast cancer.

  • Objective Response as Determined by the Investigator Using Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Baseline to the data cut-off date of 31 Jul 2008 (up to 2 years, 7 months) ] [ Designated as safety issue: No ]
    An objective response was defined as a complete response or a partial response determined on two consecutive occasions ≥ 4 weeks apart as determined by the investigator using RECIST. For target lesions, a complete response was defined as the disappearance of all target lesions; a partial response was defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter. For non-target lesions, a complete response was defined as the disappearance of all non-target lesions; a partial response was defined as the persistence of 1 or more non-target lesions.
  • Duration of Objective Response as Determined by the Investigator Using Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Baseline to the data cut-off date of 31 Jul 2008 (up to 2 years, 7 months) ] [ Designated as safety issue: No ]
    Duration of objective response was defined as the time from the first tumor assessment that led to a determination of an objective response to the time of disease progression or death due to any cause, whichever occurred first.
  • Overall Survival [ Time Frame: Baseline to the data cut-off of 23 Feb 2009 (up to 3 years, 2 months) ] [ Designated as safety issue: No ]
    Overall survival was defined as the time from randomization until death from any cause.
  • 1-year Survival [ Time Frame: Baseline to the data cut-off of 23 Feb 2009 (up to 3 years, 2 months) ] [ Designated as safety issue: No ]

    1-year survival was defined as the percentage of patients who were alive 1 year after randomization.

    The percentage of patients alive at 1 year was determined using Kaplan-Meier analyses and the 95% confidence intervals were computed using the Brookmeyer-Crowley method.

  • Progression-free Survival (PFS) as Determined by the Independent Review Committee Using Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Baseline to the data cut-off date of 31 Jul 2008 (up to 2 years, 7 months) ] [ Designated as safety issue: No ]
    PFS was defined as the time from randomization to first documented disease progression (PD) as determined by the Independent Review Committee using Response Evaluation Criteria in Solid Tumors (RECIST) or death due to any cause, whichever occurred first.

A Study Evaluating the Efficacy and Safety of Bevacizumab in Combination With Chemotherapy in Untreated Metastatic Breast Cancer (RIBBON 1)
A Multicenter, Phase III, Randomized, Placebo-controlled Trial Evaluating the Efficacy and Safety of Bevacizumab in Combination With Chemotherapy Regimens in Subjects With Previously Untreated Metastatic Breast Cancer

This is a Phase III, multicenter, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of bevacizumab in combination with chemotherapy compared with chemotherapy alone in subjects with previously untreated metastatic breast cancer.

This study includes a blinded treatment phase, an optional open-label post-progression phase, and a survival follow-up phase. During the blinded treatment phase, patients receive chemotherapy and study drug (bevacizumab or placebo) every 3 weeks until disease progression, treatment-limiting toxicity, or death due to any cause. The optional open-label post-progression phase consists of chemotherapy treatment (per investigator discretion) and optional treatment with open-label bevacizumab. Patients who complete the study or who discontinue from treatment (regardless of participation in the optional open-label post-progression phase) will be followed for survival and subsequent anti-cancer therapies every 4 months until death, withdrawal of consent, loss to follow-up, or study termination. Patients who discontinue from treatment during the blinded treatment phase for reasons other than disease progression will have tumor assessments every 9 weeks until documented disease progression or death.

Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Metastatic Breast Cancer
  • Drug: Bevacizumab
    Patients received bevacizumab until disease progression, treatment limiting toxicity, or death due to any cause up to a maximum treatment duration of 48 months. The dose of bevacizumab was based on the patient's weight at either screening or baseline and remained the same throughout the blinded treatment phase of the study. The initial dose was delivered over 90±10 minutes. If there were no infusion related adverse events (fever and/or chills), the second infusion was delivered over 60±10 minutes. If the 60 minute infusion was well tolerated, all subsequent infusions were delivered over 30±10 minutes.
    Other Name: Avastin
  • Drug: Placebo
    Placebo consisted of the vehicle for bevacizumab without the antibody.
  • Drug: Chemotherapy

    The chemotherapy was selected by the investigator prior to randomization. Chemotherapy treatment continued until disease progression, unacceptable toxicity, investigator/patient decision, or death, whichever occurred first, except for the anthracycline-based regimens, which had a maximum treatment duration of 8 cycles.

    Taxanes - 1 of the following 2 taxanes on Day 1 of every 21-day cycle

    1. Docetaxel 75-100 mg/m^2 IV
    2. Paclitaxel protein-bound particles (Abraxane®) 260 mg/m^2 IV

    Anthracyclines - 1 of the following 4 anthracycline-based regimens on Day 1 of every 21-day cycle

    1. 5-fluorouracil 500 mg/m^2 IV + epirubicin 90-100 mg/m^2 IV + cyclophosphamide 500 mg/m^2 IV
    2. 5-fluorouracil 500 mg/m^2 IV + doxorubicin 50 mg/m^2 IV + cyclophosphamide 500 mg/m^2 IV
    3. Doxorubicin 50-60 mg/m^2 IV + cyclophosphamide 500-600 mg/m^2 IV

    Capecitabine: 1000 mg/m^2 orally twice daily on Days 1-14 of each 21-day cycle

  • Experimental: Bevacizumab + chemotherapy
    Patients received bevacizumab 15 mg/kg intravenously (IV) on Day 1 of every 21-day cycle plus one of several standard chemotherapies (taxanes, anthracycline-based regimens, or capecitabine) for metastatic breast cancer.
    Interventions:
    • Drug: Bevacizumab
    • Drug: Chemotherapy
  • Placebo Comparator: Placebo + chemotherapy
