Brief Summary:
The purpose of this research study is to determine how well the combination of bevacizumab and carboplatin works in treating breast cancer that has spread to the brain. Bevacizumab is an antibody (a protein that attacks a foreign substance in the body) that is made in the laboratory. Bevacizumab works differently from the way chemotherapy drugs work. Usually chemotherapy drugs attack fast growing cancer cells in the body. Bevacizumab works to slow or stop the growth of cells in cancer tumors by decreasing the blood supply to the tumors. When the blood supply is decreased, the tumors don't get the oxygen and nutrients they need to grow. Carboplatin is in a class of drugs known as platinum-containing compounds and has been approved for use in the treatment of ovarian cancer. Information from other research studies suggests that the combination of bevacizumab with carboplatin may be effective in treating breast cancer.

Metastatic Breast Cancer Breast Cancer Progressive Breast Cancer Drug: carboplatin Drug: bevacizumab Drug: herceptin Phase 2

Detailed Description:
This study used a two-stage design to evaluate efficacy bevacizumab and carboplatin based on Central Nervous System (CNS) response. The null and alternative therapy response rates are 5% versus 20%. If 1 or more participants assessable in the stage one cohort (n=12 assessable participants) achieve CNS response then accrual proceeds to stage two (n=25 additional assessable participants). If at least 4 participants in the final set of 37 assessable participants achieve CNS response then this regimen would be deemed worthy of further study. The probability of stopping early is 0.54 if the true CNS response rate is 5% and 0.07 if the true CNS response rate is 20%. The probability of deeming the treatment worthy of further study is 0.10 and 0.90 if the true CNS response rate is 5% and 20%, respectively.

Primary Outcome Measures :
  1. Central Nervous System (CNS) Objective Response Rate [ Time Frame: Response was evaluated radiologically at baseline and every 2 cycles on treatment. Treatment duration for this study cohort was a median (range) of 8 cycles (1-20) which approximates months given the 4 week cycle length. ]

    CNS objective response rate is the percentage of participants that achieve CNS complete or partial response as follows:

    CNS complete response (CR) is achieved if all of the following are satisfied:

    • Complete resolution of all measurable (>= 1 cm in longest dimension [LD]) and non-measurable brain metastases
    • No new CNS lesions (defined as any new lesion >= 6 mm in LD)
    • Stable or decreasing steroid dose
    • No new/progressive tumor-related neurologic signs or symptoms
    • No progression of extra-CNS disease as assessed by RECIST

    CNS partial response (PR) is achieved if all of the following are satisfied:

    ->/= 50% reduction in the volumetric sum of all measurable (>/= 1 cm in LD) brain metastases compared to baseline

    • No progression on non-measurable lesions
    • No new CNS lesions (defined as any new lesion >/= 6 mm in LD)
    • Stable or decreasing steroid dose
    • No new/progressive tumor-related neurologic signs or symptoms
    • No progression of extra-CNS disease as assessed by RECIST


Secondary Outcome Measures :
  1. Progression-Free Survival [ Time Frame: Disease was evaluated radiologically at baseline, cycle 2, cycle 4 and thereafter on treatment every 2 cycles (CNS disease) and every 4 cycles (non-disease). Maximum PFS follow-up for this study cohort was 18.6 months. ]

    Progression-Free Survival (PFS) is defined as the duration of time from start of treatment to time of disease progression (PD), second cancer, or death, whichever occurs first. PD if any of the following occur:

    CNS Disease

    • >/=40% increase in the volumetric sum of all measurable lesions as compared to the smallest volume on treatment
    • Progression of non-measurable lesions
    • New lesions (>/=6 mm)

    Non-CNS Disease

    • RECIST 1.0 criteria: at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded on treatment or the appearance of >/=1 new lesions. For non-target lesions, PD is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.

    Symptomatic

    • Increasing steroid requirement
    • Global deterioration of health status requiring discontinuation of treatment
    • New/progression tumor-related neurologic signs and symptoms except for transient worsening lasting </=14 days

  2. CNS Best Response [ Time Frame: Response was evaluated radiologically at baseline and every 2 cycles on treatment. Treatment duration for this study cohort was a median (range) of 8 cycles (1-20) which approximates months given the 4 week cycle length. ]

    CNS best response was defined based on standard criteria. Adding to CR and PR (defined in the primary outcome measure):

    CNS stable disease (SD) is achieving all the following:

    • < 50% reduction in the volumetric sum of all measurable (>/= 1 cm in LD) brain metastases compared to baseline
    • No progression on non-measurable lesions
    • No new CNS lesions (defined as any new lesion >/= 6 mm in LD)
    • Stable or decreasing steroid dose
    • No new/progressive tumor-related neurologic signs or symptoms
    • No progression of extra-CNS disease as assessed by RECIST

    CNS Progressive Disease (PD) was experiencing any of the following:

    ->/- 40% increase in the volumetric sum of all measurable (>/= 1 cm in LD) brain metastases compared to baseline

    • Progression on non-measurable lesions
    • New CNS lesions (defined as any new lesion >/= 6 mm in LD)
    • Increasing steroid dose
    • New/progressive tumor-related neurologic signs or symptoms
    • Progression of extra-CNS disease as assessed by RECIST

  3. Site of First Progression [ Time Frame: Disease was evaluated radiologically at baseline, cycle 2, cycle 4 and thereafter on treatment every 2 cycles (CNS disease) and every 4 cycles (non-disease). Maximum progression follow-up for this study cohort was 18.6 months. ]

    Site of first progression is classified as follows:

    CNS Disease

    • >/=40% increase in the volumetric sum of all measurable lesions as compared to the smallest volume on treatment
    • Progression of non-measurable lesions
    • New lesions (>/=6 mm) Non-CNS Disease
    • Per RECIST 1.0 criteria: PD is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. For non-target lesions, PD is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.

    Symptomatic

    • Increasing steroid requirement
    • Global deterioration of health status requiring discontinuation of treatment
    • New/progression tumor-related neurologic signs and symptoms (NSS) except for transient worsening lasting </=14 days

  4. Overall Survival [ Time Frame: Maximum survival follow-up for the study cohort was 66 months. ]
    Participants were assessed every 6 months post-treatment. Overall survival is defined as the time from study entry to death or date last known alive and estimated using Kaplan-Meier (KM) methods.
