Whole Brain Radiotherapy (WBRT) With Sorafenib for Breast Cancer Brain Metastases (BCBM)

Completed · Phase 1

Conditions studied: Breast Cancer, Brain Metastases

In brief

Sorafenib is a new type of anti-cancer drug. It belongs to a new class of medications known as tyrosine kinase inhibitors. Sorafenib is thought to work against cancer in many ways. It helps decrease blood supply to the tumor. It also blocks some proteins that help the tumor cells to grow." Sorafenib is approved by the Food and Drug administration (FDA) for treatment for other cancers like liver and kidney cancer. Sorafenib has also been studied in the treatment of breast cancer that has spread but is not specifically approved for the treatment of breast cancer. It has been studied both as a single agent and also in combination with other anti-cancer therapies for breast cancer. In laboratory models and in some patients with other cancers, sorafenib has been studied in tumors in the brain. In this study, sorafenib will be given together with whole brain radiation therapy (WBRT). Overall this research study is designed to answer 2 main questions: 1. What dose of sorafenib should be used together with WBRT? 2. What are the side effects of sorafenib and WBRT when given together?

Who can join

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

You may qualify if…

• Histologically-confirmed metastatic adenocarcinoma of the breast (Confirmation will be done at MSKCC)
• Age ≥18 years.
• Radiologic evidence of new and/or progressive brain metastasis (≥10 mm in longest dimension) by MR imaging of the Brain
• Life expectancy of >12 weeks.
• Karnofsky Performance Status (KPS) of ≥70%
• If a patient is on corticosteroids, he/she must be on a non-escalating corticosteroid dose (not exceeding more than 16 mg daily of Dexamethasone oral) for ≥ 5 days.
• No limit to prior therapies with last anti-cancer treatment ≥ 2 weeks from initiation of protocol based therapy provided all toxicities (other than alopecia) have resolved to ≤Grade 1 or baseline.
• Planned WBRT based on number (≥ 3 lesions) and/or size (≥ 1 cm) of BMs (SRS) in addition to WBRT will also be eligible.
• Patients with prior SRS will also be eligible, provided that there are new, non-irradiated measurable brain lesions.
• No limit to prior therapies with last anti-cancer treatment ≥2 weeks from initiation of WBRT. Please note: there is no washout period required for trastuzumab and pertuzumab.
• Prior hormonal therapy for locally advanced or metastatic disease is allowed but this must have been discontinued prior to enrollment. No washout period will be required.
• Continuation of trastuzumab and pertuzumab are allowed for those patients already on trastuzumab and pertuzumab therapy.
• Adequate bone marrow, liver, and renal function as assessed by the following:
• Granulocyte count ≥ 1,000/μL, platelet count ≥ 100,000/μL, and hemoglobin ≥ 10 g/dL (hematologic parameters must be assessed at least 14 days after a prior transfusion, if any)
• Serum bilirubin ≤ 1.5 mg/dL; AST, ALT, and alkaline phosphatase ≤ 2.5 × ULN except for: Patients with hepatic metastases: ALT and AST ≤ 5 × ULN; patients with hepatic and/or bone metastases:
• alkaline phosphatase ≤ 5 × ULN and patients with Gilbert's disease: serum bilirubin < 5 mg/dL
• Serum creatinine ≤ 1.5 mg/dL or creatinine clearance of ≥ 60 mL/min based on a 24-hour urine collection
• Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to enrollment and must agree to use adequate contraception prior to enrollment and for the duration of study participation. Subjects (men and women) of childbearing potential must agree to use adequate contraception beginning at the signing of the ICF until at least 30 days after the last dose of study drug.
• Patients must be able to swallow and retain oral medication.

You may not qualify if…

• Leptomeningeal metastases, hemorrhagic metastases, presence of midline shift Please note: leptomeningeal metastases may be allowed if it is limited to cranial metastasis (MRI spine should be completed, within 4 weeks of enrollment, to show that no other leptomeningeal metastases is present) and is not the only metastasis present in the brain.'
• Contraindications to sorafenib
• Prior treatment with any agent that targets vascular endothelial growth factor (VEGF) or VEGF receptors (VEGFR) (licensed or investigational including sorafenib), except bevacizumab.
• Craniotomy or any other major surgery, open biopsy, or significant traumatic injury within 4 weeks of enrollment.
• Serious, non-healing wound, ulcer, or bone fracture.
• Uncontrolled seizures
• Use of cytochrome P450 enzyme-inducing anti-epileptic drugs (such as phenytoin, carbamazepine, or phenobarbital) is not allowed.
• Cardiac disease:
• Congestive heart failure >class II New York Heart Association (NYHA) (See Appendix B, or
• Unstable angina (anginal symptoms at rest), or new-onset angina (begun within the last 3 months), or myocardial infarction within the 6 months prior to enrollment, or
• Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
• Congenital long QT syndrome or taking drugs known to prolong the QT interval ( See Appendix D or http://www. Azcert.org )
• Subjects taking any drugs with a known risk of causing torsades de pointes.
• Grade 3 hypertension ( SBP ≥ 160 mm Hg and/or DBP ≥ 100 mm Hg despite maximal medical therapy)
• ≥ Grade 2 Lipase increased (>1.5 x ULN),
• Thrombolic, embolic, venous, or arterial events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months.
• Evidence or history of bleeding diathesis or coagulopathy at the time of enrollment.
• Pulmonary hemorrhage/bleeding event >National Cancer Institute Common Terminology for Adverse Events (NCI-CTCAE, version 4.0) Grade 2 within 4 weeks of enrollment.
• Any other hemorrhage/bleeding event ≥NCI-CTCAE Grade 3 within 4 weeks of enrollment.
• Therapeutic anticoagulation with Vitamin-K antagonists (e.g., warfarin) or with heparins and heparinoids. However, prophylactic anticoagulation as described below is allowed:
• Low dose warfarin (1 mg orally, once daily) with PT-INR ≤ 1.5 x ULN is permitted. Infrequent bleeding or elevations in PT-INR have been reported in some subjects taking warfarin while on sorafenib or capecitabine therapy. Therefore, subjects taking concomitant warfarin should be monitored regularly for changes in PT, PT-INR or clinical bleeding episodes.
• Low dose aspirin (≤ 100 mg daily).
• Active clinically serious infection >NCI-CTCAE Grade 2.
• Known human immunodeficiency virus (HIV) infection or chronic hepatitis B or C (the safety and effectiveness of sorafenib in this patient population have not been studied).
