Cabozantinib +/- Trastuzumab In Breast Cancer Patients w/ Brain Metastases

Completed · Phase 2

Conditions studied: Breast Cancer, Brain Tumor - Metastatic

In brief

This research study is evaluating the effectiveness of the drug called cabozantinib (alone or in combination with trastuzumab) as a possible treatment for advanced breast cancer in which the cancer has spread to the brain.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must have histologically or cytologically confirmed invasive breast cancer, with stage IV disease.
• New or progressive CNS lesions, as assessed by the patient's treating physician.
• For patients who have received prior cranial radiation, no increase in corticosteroid dose in the week prior to the baseline brain MRI
• Discontinued prior therapy (with the exception of trastuzumab for patients with HER2+ breast cancer)
• Recovery to baseline or ≤ Grade 1 CTCAE v.4.0 from toxicities related to any prior treatments, unless AE(s) are clinically nonsignificant and/or stable on supportive therapy;
• The subject has an ECOG performance status of 0 or 1
• Patients must have normal organ and marrow function and laboratory values as follows within 14 days before the first dose of cabozantinib
• Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) during the course of the study and for 4 months after the last dose of study drug(s)
• Subjects of childbearing potential must not be pregnant at screening.
• Patients on bisphosphonates may continue receiving bisphosphonate therapy during study. Patients wanting to initiate bisphosphonate therapy may do so.
• The subject has had an assessment of all known disease sites eg, by computerized tomography (CT) scan, magnetic resonance imaging (MRI), bone scan as appropriate, within 28 days before the first dose of cabozantinib

You may not qualify if…

• The subject has received cabozantinib or another c-Met inhibitor (please note ARQ 197 is not considered a MET inhibitor for purposes of this study given data to suggest it inhibits tubulin)
• The subject has uncontrolled, significant intercurrent or recent illness
• Leptomeningeal disease as the only site of CNS involvement
• Known contraindication to MRI with gadolinium contrast, such as cardiac pacemaker, shrapnel, or ocular foreign body
• More than 2 seizures over the last 4 weeks prior to study entry
• Grade 1 or higher CNS hemorrhage on baseline brain MRI, or history of grade 2 or higher CNS hemorrhage within 12 months
• Has experienced clinically-significant GI bleeding within 6 months before first dose of cabozantinib; hemoptysis of ≥ 0.5 teaspoon (2.5ml) of red blood within 3 months before the first dose of cabozantinib; any other signs indicative of pulmonary hemorrhage within 3 months before the first dose of cabozantinib
• The subject has tumor in contact with, invading or encasing any major blood vessels
• The subject has evidence of tumor invading the GI tract (esophagus, stomach, small or large bowel, rectum or anus), or any evidence of endotracheal or endobronchial tumor within 28 days before the first dose of cabozantinib
• The subject requires concomitant treatment, in therapeutic doses, with anticoagulants. Low dose aspirin (≤ 81 mg/day), low-dose warfarin ( ≤1 mg/day), and prophylactic LMWH are permitted.
• The subject has prothrombin time (PT)/INR or partial thromboplastin time (PTT) test ≥1.3 × the laboratory ULN within 7 days before the first dose of cabozantinib.
• Inability to swallow intact tablets
• Pregnant or lactating females
• Diagnosis of another malignancy within 2 years before the first dose of cabozantinib, except for superficial skin cancers, or localized, low grade tumors deemed cured and not treated with systemic therapy
• Subjects with clinically relevant ongoing complications from prior radiation therapy are not eligible
• The subject is known to be positive for the human immunodeficiency virus (HIV)
• Subjects with clinically relevant ongoing complications from prior surgery are not eligible
• QTcF > 500 msec on average of screening EKGs performed within 28 days of first dose of cabozantinib. Three EKGs must be performed at screening. If the average of these three consecutive results for QTcF is > 500 msec, the subject is ineligible.
• Active infection requiring IV antibiotics at Day 1 of cycle 1
• No prior lapatinib within 7 days prior to initiation of protocol treatment
• Receive concurrent investigational agents while on study
• Receive any concurrent chemotherapy, radiotherapy, or hormonal therapy while on study
• Previously identified allergy or hypersensitivity to components of the cabozantinib formulations
• The subject requires chronic concomitant treatment with strong CYP3A4 inducers
