Arm Intervention/treatment
Experimental: Lapatinib and RAD-001

RAD-001 will be administered orally as a once-daily dose of 5 mg (one 5 mg tablet) continuously from study day 1 until progression of disease or unacceptable toxicity. Patients will be instructed to take RAD-001 in the morning, at the same time each day.

Patients will be instructed to take lapatinib at bedtime, at the same time each day. Lapatinib should be taken by the patient in a fasting state.

Drug: Lapatinib and RAD-001

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)

  • Females > 18 years of age
  • Histologically proven adenocarcinoma of breast in primary or metastatic setting. Stage: Locally advanced (inoperable) or metastatic
  • HER2 positive breast cancer (IHC 3+ or FISH ratio of > 2.0)
  • ECOG Performance status 0-2
  • Up to four prior chemotherapy regimens and anti-HER2 agents in metastatic setting allowed. Must have progressed on at least one HER2 targeted therapy (lapatinib or Herceptin) for metastatic breast cancer.
  • Women of childbearing potential must have negative urine or serum pregnancy test within 7 days prior to administration of Everolimus. If barrier contraceptives are used, they must be continued throughout trial by both sexes. Hormonal contraceptives not acceptable as a sole method of contraception.
  • Adequate kidney function: serum creatinine of < 1.5 mg/dl and/or creatinine clearance of > 60 mL/min
  • Adequate hepatic function: transaminases < 2.5 x upper limit of normal (up to 5 x ULN in patients with liver metastases) and total bilirubin < 1.5 mg/dL. Adequate coagulation: INR ≤ 2.0 and PTT < 1.5 X the upper limit of institution normal range. Oral anticoagulants, eg, warfarin are CYP2C9 substrates and, as such, no interaction with Everolimus is expected. Anticoagulation with Coumadin is allowed if target INR is ≤ 2.0 and stable for > 2weeks. Anticoagulation with LMW is allowed.
  • Must be informed of investigational nature of study, and must sign an informed consent
  • Pretreatment lab values (must be performed within 14 days of patient registration unless otherwise specified. Other baseline studies must be performed within 30 days of registration.
  • Patients will have baseline CT chest, abdomen and pelvis within 30 days of registration.
  • Adequate cardiac function (LVEF ≥ 50% as measured by echocardiogram or MUGA scan).
  • Fasting serum cholesterol ≤ 300 mg/dL OR ≤ 7.75 mmol/L AND fasting triglycerides ≤ 2.5 x ULN. NOTE: In case one or both of these thresholds are exceeded, patient may be included after initiation of appropriate lipid lowering medication with approval from the principal investigator.
  • Must have measurable or non-measurable disease by RECIST criteria (version 1.1), with radiologic scans performed within 30 days of registration. Baseline scans can include:

    • CT Scan or MRI and Bone Scan OR
    • PET/CT provided it is performed with both IV and oral contrast and the CT is acquired with 5mm or less slice thickness. If IV contrast administration is contraindicated, patients should have CT scan without contrast and bone scan or MRI and bone scan.
    • MRI of brain will be used for baseline assessment and tumor response assessment for CNS lesions.
    • Patients with CNS progression without systemic progression will be allowed to remain on the protocol. Local treatment, radiation, surgery, and SRS will be allowed while on protocol as deemed necessary by the treating physician.
    • Baseline imaging method(s) should be used to determine tumor response throughout course of study.
    • Measurable disease: lesions with clearly defined margins that can be accurately measured in at least one diameter (longest diameter to be recorded) with a minimum size of:

      • 10mm by CT scan (CT scan slice thickness no greater than 5mm)
      • 10mm caliper measurement by clinical exam (lesions which cannot be accurately measured with calipers should be recorded as non-measurable)
      • 20mm by chest xray
      • Malignant lymph nodes: to be considered pathologically enlarged and measurable. Lymph node must be > 15mm in short axis when assessed by CT scan. At baseline and in follow-up, only short axis will be measured and followed.
    • Non-measurable disease: all other lesions including small lesions (longest diameter < 10mm or pathological lymph nodes with > to <15 mm (short axis), and masses with margins not clearly defined. Lesions that are considered non-measurable include:
