Temozolomide and Bevacizumab in Treating Patients With Stage IV Melanoma That Cannot Be Removed By Surgery

• Status: Completed
• Trial end date: 2011-10-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving temozolomide together with bevacizumab may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving temozolomide together with bevacizumab works in treating patients with stage IV melanoma that cannot be removed by surgery.

• Serum total bilirubin ≤ 1.5 times upper limit of normal (ULN)

• ALT and alkaline phosphatase ≤ 2.5 times ULN (5 times ULN in patients with liver metastases)

• Fertile patients must use effective contraception during and for 12 months after completion of study treatment

• No other primary tumors within the past 5 years, except adequately controlled limited basal cell or squamous cell skin cancer or carcinoma in situ of the cervix

• No history or evidence of CNS disease unrelated to cancer (e.g., uncontrolled seizures) by physical/neurological examination, unless adequately treated with standard medical therapy

• No frequent vomiting or any other pre-existing medical condition that would preclude swallowing and/or absorption of oral medication

• No history or evidence of inherited bleeding diathesis or coagulopathy with risk of bleeding

• No uncontrolled hypertension (i.e., systolic blood pressure > 150 mm Hg and/or diastolic blood pressure > 100 mm Hg, measured repeatedly, despite adequate treatment with at least two different antihypertensive drugs)

• No clinically significant (i.e., active) cardiovascular disease, including any of the following:

• Cerebrovascular accident/stroke or myocardial infarction within the past 6 months

• Unstable angina

• New York Heart Association (NYHA) class II or greater congestive heart failure

• Serious cardiac arrhythmia (i.e., ventricular arrhythmia, high-grade atrioventricular-block) that requires medication during the study, interferes with regularity of the study treatment, or is uncontrolled by medication

• No serious non-healing wound, active peptic ulcer, or non-healing bone fracture

• No abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within the past 6 months

• No significant traumatic injury within the past 30 days

• No uncontrolled active infection

• No known HIV infection

• No known hypersensitivity to any of the study drugs or excipients

• No evidence of any other disease, metabolic or psychological dysfunction, psychiatric disorder, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug, or that may affect patient compliance with study routines, or places the patient at high risk from treatment-related complications
