  Purpose

Purpose: This study is a single-arm, open-label phase II clinical trial testing the hypothesis that daily everolimus plus weekly vinorelbine and trastuzumab will be effective, safe, and tolerable among patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer brain metastases. Once enrolled, patients will receive everolimus PO daily in combination with weekly intravenous (IV) vinorelbine and trastuzumab. Cycles will be repeated every 3 weeks (21 days). At the time of progression, patients will come off study.

Participants: Up to 35 adults over 21 with HER-2 positive breast cancer that has metastasized to the brain.

Primary Outcome Measures:
  • Intracranial Objective Response Rate- Modified RECIST Criteria [ Time Frame: 3 years ]

    response will be evaluated via gadolinium-enhanced brain MRI using modified RECIST criteria.

    Complete Response (CR) - Disappearance of all target and nontarget lesions

    Partial Response (PR) - at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum longest diameter AND an absolute decrease of at least 5mm in at least one target lesion.

    Stable Disease (SD) - neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum of the longest diameter since the treatment started.

    Progressive Disease (PD) - at least a 20% increase in the sum LD of target lesions, taking as reference the smallest sum of the longest diameter recorded since the treatment started AND an absolute increase in size of at least 5 mm in at least one target lesion OR the appearance of one or more new lesions of at least 6 mm in size.



Secondary Outcome Measures:
  • Intracranial Response Rate- MacDonald Criteria [ Time Frame: 3 years ]

    Intracranial tumor lesions were evaluated via gadolinium-enhanced brain MRI using the MacDonald criteria. Measurable disease is defined as at least 1 measurable brain lesion accurately measured in at least 2 dimensions (longest diameter) as ≥5.0 mm. Tumor size is the product of the 2 longest bi-dimensional lines.

    Complete Response (CR)- Disappearance of all tumor on consecutive CT or MRI scans at least 1 month apart, off steroids for treatment of neurological symptoms, and neurologically stable or improved.

    Partial Response (PR)- ≥50% reduction in size of tumor on consecutive CT or MRI scans at least 1 month part, steroids stable or reduced, and neurologically stable or improved.

    Progressive Disease (PD)- ≥25% increase in size of tumor or any new tumor on CT or MRI scans, or neurologically worse, and steroids stable or increased due to neurologic symptoms.

    Stable Disease (SD)- all other situations Overall Response Rate (ORR) is the sum of partial responses (PRs) and CRs.


  • Toxicity [ Time Frame: 24 weeks ]

    Grade 3 or higher toxicities of interest are reported. Toxicity was assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.

    The NCI CTCAE is a descriptive terminology which can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.


  • Time to Intracranial Progression. [ Time Frame: 3 years ]

    Time to intracranial progression after administration of everolimus in combination with trastuzumab and vinorelbine as defined via modified RECIST criteria.

    Progressive Disease (PD) - at least a 20% increase in the sum LD of target lesions, taking as reference the smallest sum of the longest diameter recorded since the treatment started AND an absolute increase in size of at least 5 mm in at least one target lesion OR the appearance of one or more new lesions of at least 6 mm in size.


  • Extracranial Response [ Time Frame: 3 years ]

    Extracranial response was measured using RECIST 1.1 criteria and defined as the number of subjects achieving CR or PR.

    Complete Response (CR) - Disappearance of all target and nontarget lesions Partial Response (PR) - at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum longest diameter AND an absolute decrease of at least 5mm in at least one target lesion.

    Stable Disease (SD) - neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum of the longest diameter since the treatment started.

    Progressive Disease (PD) - at least a 20% increase in the sum LD of target lesions, taking as reference the smallest sum of the longest diameter recorded since the treatment started AND an absolute increase in size of at least 5 mm in at least one target lesion OR the appearance of one or more new lesions of at least 6 mm in size.


  • Extracranial Time to Progression [ Time Frame: 3 years ]

    To evaluate the extracranial time to progression as determined by RECIST 1.1 criteria after administration of everolimus in combination with trastuzumab and vinorelbine.

    Progressive Disease (PD) - at least a 20% increase in the sum LD of target lesions, taking as reference the smallest sum of the longest diameter recorded since the treatment started AND an absolute increase in size of at least 5 mm in at least one target lesion OR the appearance of one or more new lesions of at least 6 mm in size.


  • Overall Survival [ Time Frame: 3 years ]
    Overall survival (OS) after administration of everolimus in combination with trastuzumab and vinorelbine

  • Functional Assessment of Cancer Therapy- Brain (FACT-Br) Change From Baseline to Assess Impact of Everolimus in Combination With Trastuzumab and Vinorelbine on Quality of Life [ Time Frame: 9 weeks ]
    The FACT-Br is a 23-question self-report questionnaire subscale administered with the Functional Assessment of Cancer Therapy- General (FACT-G) which contains concerns relevant to patients with brain tumors . Each question has a value 0-4. For some questions a higher indicates better outcome and others are the opposite. The former are summed as is, the latter are reversed in value before adding, such that each domain ranges from 0 to 4 times the number of questions in the domain, with 0 indicating worst and the highest possible value indicating best outcome. Total scores on the FACT-Br subscale range from 0 to 92 with lower scores indicating declining quality of life. The change from baseline is the difference in scores between the baseline and 9 week assessments.

  • Functional Assessment Cancer Therapy- Breast (FACT-B) From Baseline to 9 Weeks of Treatment to Assess Impact of Everolimus in Combination With Trastuzumab and Vinorelbine on Quality of Life [ Time Frame: 9 weeks ]
    The FACT-B is a 10-question self-report questionnaire subscale administered with the Functional Assessment of Cancer Therapy- General (FACT-G) which contains concerns relevant to patients with breast cancer. Each question has a value 0-4. For some questions a higher indicates better outcome and others are the opposite. The former are summed as is, the latter are reversed in value before adding, such that each domain ranges from 0 to 4 times the number of questions in the domain, with 0 indicating worst and the highest possible value indicating best outcome. Total scores on the FACT-B subscale range from 0 to 40 with lower scores indicating declining quality of life. The change from baseline is the difference in scores between the baseline and 9 week assessments.

Exploratory Objective

-To evaluate biomarkers in archival tumor tissue samples and correlate with therapeutic response to everolimus in combination with vinorelbine and trastuzumab.

Following Hepatitis B antiviral prophylaxis if required, or following screening and informed consent if antiviral therapy is not needed, treatment will be initiated with everolimus PO daily in combination with weekly intravenous (IV) vinorelbine and trastuzumab (Days 1, 8, and 15)

A cycle is defined as 3 weeks (21 days). Cycles of therapy will be repeated until documented disease progression, unacceptable toxicity, or patient withdrawal from study for other reasons, including death.
