Sorafenib, Bevacizumab, and Oxaliplatin in Treating Patients With Metastatic Malignant Melanoma

A Phase I/II Trial of Nexavar, Avastin and Eloxatin in Patients With Metastatic Malignant Melanoma

RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 malignant melanoma by blocking blood flow to the tumor. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with bevacizumab and oxaliplatin may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side-effects and best dose of sorafenib when given together with bevacizumab and oxaliplatin and to see how well it works in treating patients with metastatic malignant melanoma.

OBJECTIVES:

• To determine the maximum tolerated dose of sorafenib tosylate when administered with bevacizumab and oxaliplatin.
• To determine the effect of this treatment regimen on the complete and partial response rate in patients with metastatic melanoma.
• To determine the effect of this treatment regimen on the progression-free and overall survival of patients with metastatic melanoma.

OUTLINE: This is a phase I dose-escalation study of sorafenib tosylate followed by a phase II study.

• Phase I: Patients receive bevacizumab IV over 30-90 minutes and oxaliplatin IV over 2 hours on day 1. Patients also receive oral sorafenib tosylate twice daily on days 1-14. Treatment repeats every 2 weeks in the absence of disease progression or unacceptable toxicity.
• Phase II: Patients receive sorafenib tosylate at the maximum tolerated dose and bevacizumab and oxaliplatin as in phase I.

After completion of study therapy, patients are followed for at least 5 years.

DISEASE CHARACTERISTICS:

• Histologically confirmed melanoma

  • Metastatic disease

• Measurable or evaluable non-CNS disease

  • Measurable disease, defined as a unidimensionally measurable lesion as determined by physical exam, x-ray, CT scan, MRI, or other radiographic procedure

  • Evaluable disease, defined as a lesion that can be seen radiographically but is not unidimensionally measurable

    • Previously irradiated lesions with documented progression are allowed provided there are no other sites of metastatic disease

• No active brain metastases

  • Previously treated, responding brain metastases allowed, provided there is measurable disease outside of the CNS

    • At least 3 weeks since prior chemotherapy and 6 weeks since prior radiotherapy for CNS disease
