lenalidomide, sunitinib, and cyclophosphamide in treating patients with stage iv eye melanoma

Conditions: Intraocular Melanoma; Malignant Conjunctival Neoplasm

Summary: rationale: lenalidomide may stop the growth of tumor cells by blocking blood flow to the tumor. sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. giving lenalidomide together with sunitinib and low doses of cyclophosphamide once a day may kill more tumor cells. purpose: this phase ii trial is studying how well giving lenalidomide together with sunitinib and cyclophosphamide works in treating patients with stage iv eye melanoma.

objectives: primary * determine the response rate in patients with stage iv ocular melanoma treated with lenalidomide, sunitinib malate, and low-dose metronomic cyclophosphamide. secondary * determine the toxicity of this regimen in these patients. * determine the progression-free survival of patients treated with this regimen. * obtain blood, urine, and tissue samples from these patients, when easily accessible, to determine the effects of this regimen on pathways thought to have been modulated by this regimen in pre-clinical studies. outline: this is nonrandomized, uncontrolled, open-label study. patients receive oral lenalidomide, oral sunitinib malate\*, and oral low-dose cyclophosphamide once daily on days 1-28. treatment repeats every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. note: \*some patients will not receive sunitinib malate during course 1. after completion of study treatment, patients are followed every 3 months for 2 years, every 4 months for 3 years and then annually thereafter.
