研究概览
简要总结
RATIONALE: Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. Stereotactic radiosurgery (SRS) may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Giving sorafenib tosylate together with SRS may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and the best dose of sorafenib tosylate when given together with SRS in treating patients with brain metastases
详细描述
PRIMARY OBJECTIVES:
I. To determine the safety, tolerability and maximum tolerated dose (MTD) of sorafenib, when administered in combination with SRS to patients with 1-4 metastatic brain tumors.
SECONDARY OBJECTIVES:
I. To assess the six-month intra-cranial progression-free survival (PFS) of sorafenib when administered in combination with SRS to patients with 1-4 metastatic brain tumors. PFS is defined as the time to intra-cranial tumor progression or death.
II. To assess the six-month overall survival (OS) of sorafenib when administered in combination with SRS to patients with 1-4 metastatic brain tumors.

入选标准
- •Histologically confirmed cancer with 1-4 brain metastases (except lymphoma or small cell histologies)
- •ECOG PS 0 or 1
- •Patients are candidates for stereotactic radiosurgery as determined by the treating radiation oncologist. Intra-cranial tumors must measure 4cm or less in greatest dimension. Patients may have received prior neurosurgical resection(s) of intra-cranial metastases if their operation(s) was (were) completed at least 6 months prior to study enrollment. Patients may have had prior whole brain radiation therapy (WBRT) if it was completed at least 6 months prior to study enrollment.
- •Age ≥ 18 years and willing and able to sign a written informed consent; a signed informed consent must be obtained prior to any study specific procedures
- •INR < 1.5 or a PT/PTT within normal limits; patients receiving anti-coagulation treatment with an agent such as warfarin or heparin may be allowed to participate; for patients on warfarin, the INR should be measured prior to initiation of sorafenib and monitored at least weekly (INR must be therapeutic in the range of 2-3)
- •Subjects must receive 1st dose of sorafenib 5-7 days prior to administration of Stereotactic Radiosurgery.
排除标准

- •Unable to undergo brain MRI
- •CNS metastases from lymphoma or small cell lung cancer
- •Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy
- •Uncontrolled hypertension defined as systolic blood pressure > 140mm Hg or diastolic pressure > 90 mm Hg, despite optimal medical management
- •Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C
- •Active clinically serious infection > CTCAE v 4.0 Grade 2
- •Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months
- •Pulmonary hemorrhage/bleeding event >= CTCAE v 3.0 Grade 2 within 4 weeks of first dose of study drug
- •Any other hemorrhage/bleeding event >= CTCAE v 3.0 Grade 3 within 4 weeks of first dose of study drug
- •Serious non-healing wound, ulcer, or bone fracture
- •Any drug that results in hepatic enzyme induction such as anti-convulsants (dilantin, depakote, tegretol, phenobarbital); keppra is allowed
- •Evidence or history of bleeding diathesis or coagulopathy
- •Any pulmonary hemorrhage CTCAE v 4.0 Grade 2 or higher within 4 weeks of first study drug
- •Any other bleeding or hemorrhage CTCAE v 4.0 Grade 3 or higher within 4 weeks of first drug
- •Major surgery, open biopsy or significant traumatic injury within 4 weeks of first study drug
- •Use of St. John's Wort or rifampin (rifampicin) within the last 8 weeks
- •Known or suspected allergy to sorafenib
- •Any condition that impairs patient's ability to swallow whole pills
- •Concurrent investigational drugs
- •Concurrent steroids are allowed if Dexamethasone dose is =< 16mg daily; if feasible, steroids should be weaned off once sorafenib has been initiated
- •Prior therapy with sorafenib or other tyrosine kinase inhibitors within the last 12 months; patients are allowed to have been on prior bevacizumab therapy as long as it was stopped at least 6-8 weeks prior to enrolling on this trial
- •Any malabsorption problem
- •Hemoglobin =< 9.0 g/dl
- •Absolute neutrophil count (ANC) =< 1,500/mm^3
- •Platelet count =< 100,000/mm^3

- •ALT and AST >= 2.5 times the ULN ( =< 5 x ULN for patients with liver involvement)
- •Creatinine >= 1.5 times ULN
- •Women of childbearing potential with a positive serum pregnancy test performed within 7 days prior to the start of treatment; women and men of childbearing potential that do not agree to use adequate contraception (barrier method of birth control) prior to study entry and for the duration of study participation; men who do not agree to use adequate birth control for at least three months after the last administration of sorafenib
- •All toxicities from prior therapies must have resolved to CTCAE v3.0 Grade I or better by the time of study enrollment
