- Maximum tolerated dose (MTD) of sorafenib tosylate in patients with recurrent or progressive malignant glioma, receiving (group A) or not receiving (group B) anticonvulsants known to be metabolized by the P450 hepatic enzyme complex
研究概览
简要总结
This phase I trial is studying the side effects and best dose of sorafenib in treating patients with recurrent or progressive malignant glioma. Sorafenib may stop the growth of tumor cells by stopping blood flow to the tumor and by blocking the enzymes necessary for their growth.
详细描述
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of BAY 43-9006 when administered to adults with recurrent malignant glioma, receiving (Group A) or not receiving (Group B) anticonvulsants known to be metabolized by the P450 hepatic enzyme complex.
II. To assess and estimate the dose-related toxicities. III. To describe the pharmacokinetics of this route of administration, measuring BAY 43-9006, and to assess the pharmacokinetic difference between patients taking enzyme-inducing agents and those who are not.
IV. To estimate overall survival.
OUTLINE: This is a dose-escalation, multicenter study. Patients are stratified according to the concurrent use of cytochrome P450-inducing anticonvulsants (yes vs no).

入选标准
- •Patients must have histologically proven malignant glioma (anaplastic astrocytoma, anaplastic oligodendroglioma or glioblastoma multiforme) which is progressive or recurrent after radiation therapy ± chemotherapy; patients with previous low grade glioma who progressed after radiotherapy ± chemotherapy and are biopsied and found to have a high grade glioma are eligible
- •Patients must have measurable progressive or recurrent malignant glioma by MRI or CT imaging; (Within 14 days before starting treatment)
- •Patients must have recovered from toxicity of prior therapy; an interval of at least 3 months must have elapsed since the completion of the most recent course of radiation therapy, while at least 3 weeks must have elapsed since the completion of a non-nitrosourea containing chemotherapy regimen, and at least 6 weeks since the completion of a nitrosourea containing chemotherapy regimen
- •Patients must have a Karnofsky performance status >= 60% (i.e. the patient must be able to care for himself/herself with occasional help from others)
- •Absolute Neutrophil Count >= 1500/mm^3
- •Platelets >= 100,000/mm^3
- •Creatinine =< 1.7mg/dl
- •Total Bilirubin =< 1.5mg/dl
- •Transaminases =< 4 times above the upper limits of the institutional norm
- •PT, PTT, INR within institutional norm
- •Patients must be able to provide written informed consent
- •Patients with the potential for pregnancy or impregnating their partner must agree to follow acceptable birth control methods to avoid conception; women of childbearing potential must have a negative serum pregnancy test; (The anti-proliferative activity of this experimental drug may be harmful to the developing fetus or nursing infant)
- •Patients must have a Mini Mental State Exam score >= 15
排除标准
- •Patients with serious concurrent infection or medical illness which would jeopardize the ability of the patient to receive the treatment outlined in this protocol with reasonable safety; (Examples of medical illnesses are [but not limited to] the following: uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation that would limit compliance with study requirements)
- •Patients who are pregnant or breast-feeding; (The anti-proliferative activity of this experimental drug may be harmful to the developing fetus or nursing infant)
- •Patients who have received more than two prior treatments
- •Patients receiving concurrent therapy for their tumor (with the exception of steroids)
- •Patients with a concurrent malignancy are ineligible unless they are patients with curatively treated carcinoma-in-situ or basal cell carcinoma of the skin; patients with a prior malignancy are ineligible unless they have been free of disease for >= five years
- •Patients must not have any evidence of bleeding diathesis
- •Patients must not be on therapeutic anticoagulation; prophylactic anticoagulation (i.e. low dose warfarin) of venous or arterial access devices is allowed provided that the requirements for PT, INR or PTT are met; (Patients will be taken off treatment if they require therapeutic anticoagulation during BAY 43-9006 treatment)
研究组 & 干预措施
Treatment (sorafenib tosylate)
Patients receive oral sorafenib twice daily on days 1-28 (once daily on day 1 of course 1 only). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients per stratum receive escalating doses of sorafenib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 3 of 6 patients experience dose-limiting toxicity.
