This phase II trial studies how well axitinib works in treating patients with melanoma that has spread to other places in the body or cannot be removed by surgery. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVES: I. To determine the overall response rate (ORR) to axitinib in advanced melanoma. This will be assessed using the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. SECONDARY OBJECTIVES: I. Evaluate toxicity of axitinib as a single agent. II. Determine progression-free survival and overall survival. III. Explore the utility of 3'-deoxy-3'-\[18F\] fluorothymidine-labeled positron emission tomography (FLT-PET) as a predictive marker for response and compare to standard radiographic imaging. TERTIARY OBJECTIVES: I. Examine the prognostic and predictive significance of circulating melanoma tumor cells. II. To examine whether functionally relevant polymorphisms in axitinib-related genes (vascular endothelial growth factor receptor \[VEGFR\] 1, VEGFR2 and VEGFR3) correlate with efficacy and toxicity of axitinib in advanced melanoma. OUTLINE: Patients receive axitinib orally (PO) twice daily (BID). Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days.

Overall Response Rate (Complete Response + Partial Response) to Axitinib as Assessed Using RECIST Version 1.1
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Time frame: Up to 30 days
Number of Patients That Experienced at Least One Grade 3 Adverse Event
Number of patients that experienced at least one grade 3 toxicity regardless of attribution. Incidence of toxicity of axitinib as a single agent as assessed by the severity of adverse effects by NCI CTCAE version 4. Please refer to the adverse event reporting for more detail.
Time frame: Up to 30 days
Median Progression-free Survival (PFS)
The distribution will be described using Kaplan-Meier and proportional hazards methods. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
Time frame: From the date of study enrollment to the first observation of progressive disease or death within 30 days after last dose of study drug
Median Overall Survival (OS)
The distribution will be described using Kaplan-Meier and proportional hazards methods.
Time frame: From the date of study enrollment to the time of death within 30 days after last dose of study drug
The Baseline Circulative Tumor Cells Value of Responders
The baseline Circulative tumor Cells values of patients with response to treatment per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR. CTC were evaluated at baseline, response was assessed up to 30 days.
Time frame: Baseline
