Crizotinib in High-Risk Uveal Melanoma Following Definitive Therapy

Inclusion Criteria:

* Primary diagnosis of uveal melanoma at least 12 mm in largest basal diameter as clinically determined by the treating investigator. Cytologic determination of diagnosis is not required. Size is based on clinical assessment (e.g. by ultrasound or direct ophthalmoscopy) prior to enucleation or radiation therapy.
* Definitive therapy of the primary uveal melanoma must have been performed within 90 days of initiating protocol therapy.
* High-risk (class 2) uveal melanoma as determined by gene expression profiling
* No evidence of metastatic disease.
* Age ≥18 years.
* Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 (Karnofsky ≥ 70%.
* Life expectancy of greater than 3 months.
* Able to swallow and retain orally-administered medication and does not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels
* Patients must have normal organ and marrow function as defined below:
* Absolute neutrophil count (ANC) \>1,000 cells/mm³
* Platelet count \>75,000/mm³
* Hemoglobin \>9.0g/dL
* Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) \<3x upper limited of normal (ULN)
* Total bilirubin \<2x ULN
* Alkaline phosphatase \<3x ULN
* Serum creatinine \<2x ULN or a creatinine clearance \> 60mL/min
* Note: Patients with hyperbilirubinemia clinically consistent with an inherited disorder of bilirubin metabolism (e.g., Gilbert syndrome) will be eligible at the discretion of the treating physician and/or the principal investigator.
* Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation until 4 months after completion of crizotinib administration. Women of child-bearing potential must have a negative serum pregnancy test within 14 days prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study therapy, and 4 months after completion of crizotinib administration.
* Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

* History of another malignancy except for those who have been disease-free for 3 years, or patients with a history of completely resected non-melanoma skin cancer and/or patients with indolent secondary malignancies not requiring active therapy, are eligible. Consult the study Principal Investigator if unsure whether second malignancies meet the requirements specified above.
* Any major surgery or extensive radiotherapy (except that which is required for definitive treatment of primary uveal melanoma), chemotherapy with delayed toxicity, biologic therapy, or immunotherapy within 21 days prior to initiation of study therapy.
* History of prior crizotinib use.
* Use of other investigational drugs within 28 days (or five half-lives, whichever is shorter; with a minimum of 14 days from the last dose) preceding the first dose of study therapy and during the study.
* Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to crizotinib.
* Concurrent administration of crizotinib and a strong inhibitor or inducer of CYP3A is not permitted. Many over-the-counter and dietary supplements also inhibit or induce CYP3A and thus are prohibited.
* A QT interval corrected for heart rate using the Bazett's formula QTcB ≥ 480 msec.
* Concurrent administration of crizotinib and agents that can cause QTc prolongation is not permitted.
* Known Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection (with the exception of chronic or cleared HBV and HCV infection, which will be allowed). HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with crizotinib. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy.
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
