Summary

This randomized phase II trial studies how well sunitinib malate or valproic acid works in preventing high-risk uveal (eye) melanoma from spreading to other parts of the body. Sunitinib malate may stop the transmission of growth signals into tumor cells and prevents these cells from growing. Valproic acid may change the expression of some genes in uveal melanoma and suppress tumor growth.

Clinical Details

Official title: A Randomized Phase ll Study of Adjuvant Sunitinib or Valproic Acid in High-Risk Patients With Uveal Melanoma

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Overall survival

Secondary outcome:

Relapse-free survival

Tolerability

Detailed description: PRIMARY OBJECTIVES: 1) To assess the efficacy of adjuvant sunitinib malate or adjuvant valproic acid used for 6 months to improve overall survival (OS) at 2 years in patients with high-risk uveal melanoma. SECONDARY OBJECTIVES: 1. To assess the efficacy of adjuvant sunitinib malate and adjuvant valproic acid used for 6 months in preventing the development of distal metastases (relapse-free survival, RFS) in patients with high-risk uveal melanoma. 2. To confirm the safety and tolerability of 6 months of adjuvant sunitinib and adjuvant valproic acid in patients with high-risk uveal melanoma. 3. To assess the quality of life during the adjuvant treatment. TERTIARY OBJECTIVES: 1) To determine whether blood myeloid-derived suppressor cells (MDSCs) concentration and other inflammatory cytokines correlates with OS and RFS. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive sunitinib malate orally (PO) daily for 6 months in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive valproic acid PO daily for 6 months in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria: 1. Age >= 18 years old. 2. Histologically-confirmed primary uveal melanoma. 3. Definitive local treatment for primary tumor, including surgical resection (enucleation) or radiation therapy (radioactive plaque or external proton beam).

4. High risk for distal recurrence defined as any of the following conditions: A) -

Confirmed both monosomy 3 and 8q amplification; B) - Class II tumor.

5. Less than 6 months from the date that local treatment (surgical or radiation) of the primary tumor was finalized. 6. Karnofsky performance status (PS) scores of 70 or greater. 7. If female, no pregnancy. 8. If of child-bearing potential (< one year post-menopausal), must agree to practice an effective method of avoiding pregnancy (including oral or implanted contraceptives, intrauterine device, condom, diaphragm with spermicidal, cervical cap, abstinence or sterile sex partner) from the time informed consent is signed (women only) or the time of initiation of sunitinib (men only); both men and women must agree to continue using such precautions while receiving sunitinib or valproic acid and for 30 days after the final dose. 9. Adequate organ function that has been determined within 2 weeks prior to the study entry, defined as:

- Absolute neutrophil count (ANC) ≥ 1500/mm3, platelets ≥ 100,000/mm3, and

hemoglobin ≥ 8 g/dl

- Serum creatinine < 1. 5 times upper limit of normal range (ULN) or creatinine

clearance ≥ 40 ml/min

- Serum bilirubin < 1. 5 times ULN and serum albumin > 2. 0 g/dl

- Adequate cardiac function (EF> 50%) based on MUGA scan

Exclusion Criteria: 1. Other malignancy within 5 years, except curatively treated non-melanomatous skin cancer, curatively treated carcinoma in situ of the uterine cervix, or early stage (stage I or IIa) prostate cancer. 2. Metastatic uveal melanoma. 3. History of severe allergic reaction to sunitinib or valproic acid; inability to receive sunitinib or valproic acid. 4. Previous treatment with sunitinib or valproic acid for uveal melanoma. 5. Active treatment with valproic acid for non-oncological conditions, if this cannot be safely switched to an alternative agent. 6. Active epilepsy or convulsive conditions that require continuous use of anticonvulsants. 7. Patients with known urea cycle disorders (i. e.: ornithine transcarbamylase deficiency). 8. Severe cardiovascular disease within 6 months, including myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure, cerebro-vascular accident or transient ischemic attack, pulmonary embolism, life threatening arrhythmias, uncontrollable hypertension or QT prolongation syndrome. 9. History of active liver disease (i. e. cirrhosis, viral or autoimmune hepatitis, etc.). 10. Pregnancy or unwillingness to stop breast-feeding. 11. Prior myelosuppressive chemotherapy or other investigational drug therapy within the last 6 months prior to initiation of sunitinib or valproic acid. 12. Current evidence of hematemesis, melena or gross hematuria. 13. History or presence of any significant bleeding disorders. 14. Concurrent use of a strong CYP3A4 inhibitor or inducer (refer to Section 7). These medications should be discontinued or switched to a different medication with a weaker CYP3A4 interaction prior to enrollment into the study. If patients need to continue the same medication(s), they are excluded from the study. 15. Chronic usage of aspirin greater than 81 mg/day. 16. Unable to render informed consent and to follow protocol requirements.
