Brief summary:
This phase II trial is studying how well dasatinib works in treating patients with stage III melanoma that cannot be removed by surgery or stage IV melanoma. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description:
PRIMARY OBJECTIVES:

I. Determine the objective response rate in patients with stage III unresectable or stage IV melanoma treated with dasatinib.

II. Determine the progression-free survival of patients treated with this drug.

SECONDARY OBJECTIVES:

I. To assess the expression of targets of Dasatinib prior to treatment by obtaining pre-treatment biopsies or examining paraffin-embedded tissues from previous tumor resections.

II. In selected patients (approximately 5-10) where tumor tissue is available pre-treatment and can be obtained post-treatment with Dasatinib (21 days after initiation of therapy), to determine if Dasatinib induces changes in expression of selected targets and downstream mediators, including MEK, ERK and RSK-1.

III. To assess toxicity.

OUTLINE:

Patients receive oral dasatinib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks.

Arms:
arm 1: Patients receive oral dasatinib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Interventions: intervention 1: dasatinib
