Mesothelioma Related Clinical Trials:
A Phase II Trial of SU5416 (NSC# 696819) in Patients With Malignant Mesothelioma

OBJECTIVES: I. Determine the objective response rate, median and overall survival, and time to progression in patients with unresectable malignant mesothelioma treated with SU5416. II. Determine the effect of SU5416 on surrogate biologic endpoints, including microvessel density, tissue proliferative index, apoptosis, vascular endothelial growth factor levels, and tumor perfusion measured by MRI in these patients. III. Determine the toxicity of this regimen in these patients.

OUTLINE: This is a multicenter study. Patients receive SU5416 IV over 1 hour twice weekly. Courses repeat every 4 weeks for a minimum of 2 courses in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: Approximately 21-45 patients will be accrued for this study within 18-24 months.

DISEASE CHARACTERISTICS: Histologically or cytologically proven malignant mesothelioma (epithelial, sarcomatoid, or mixed subtype) that is not amenable to surgery or radiotherapy Measurable disease At least 20 mm by conventional techniques or at least 10 mm by spiral CT scan Pleural effusions and ascites are not considered measurable lesions Only site of measurable disease must not be located within prior radiotherapy port Lesion must be accessible for biopsy History of previously treated CNS metastasis allowed if: Neurologically stable No requirement for IV or oral steroids or IV anticonvulsants No active or residual disease by brain CT or MRI scan Patients with neurologic signs or symptoms suggestive of CNS metastasis must have a negative brain CT or MRI scan

PATIENT CHARACTERISTICS: Age: 18 and over Performance status: WHO 0-2 Life expectancy: At least 12 weeks Hematopoietic: WBC at least 3,000/mm3 Platelet count at least 75,000/mm3 Hepatic: Bilirubin no greater than 1.5 mg/dL SGOT and SGPT no greater than 2.5 times upper limit of normal Renal: Creatinine no greater than 1.5 mg/dL OR Creatinine clearance at least 60 mL/min Cardiovascular: No uncompensated coronary artery disease on electrocardiogram or physical examination No history of myocardial infarction or severe/unstable angina within the past 6 months No severe peripheral vascular disease associated with diabetes mellitus No deep vein or arterial thrombosis within the past 3 months Pulmonary: No pulmonary embolism within the past 3 months Other: No significant uncontrolled underlying medical or psychiatric illness No serious active infection Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception No active second malignancy except nonmelanomatous skin cancer or carcinoma in situ of the cervix Patients are not considered to have active malignancy if they have completed therapy and are considered to be at less than 30% risk of relapse No history of severe allergic or anaphylactic reactions to paclitaxel or docetaxel
