Sunitinib Malate or Valproic Acid in Preventing Metastasis in Patients With High-Risk Uveal Melanoma
brief 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.
detailed description
PRIMARY OBJECTIVES:
I. To assess the efficacy of adjuvant sunitinib malatate (sunitinib) and adjuvant valproic acid used for 6 months to improve overall survival (OS) at 2 years in patients with high risk uveal melanoma. (Cohort 1) II. To assess the efficacy of adjuvant sunitinib used for 12 months to improve 1.5-year relapse free survival (RFS) in patients with high-risk uveal melanoma. (Cohort 2) III. To assess whether the combination of sunitinib and valproic acid used for 12 months improve the 2-year relapse free survival (RFS) in patients with high-risk uveal melanoma. (Cohort 3)
SECONDARY OBJECTIVES:
I. To assess the efficacy of adjuvant sunitinib, in terms of RFS and adjuvant valproic acid used for 6 months in preventing the development of distal metastases in patients with high risk uveal melanoma. (Cohort 1) II. To assess the efficacy of adjuvant sunitinib, in terms of OS, used for 12 months in patients with high risk uveal melanoma. (Cohort 2) III. To assess the efficacy of adjuvant sunitinib in combination with valproic acid, in terms of OS in patients with high risk uveal melanoma. (Cohort 3) IV. To confirm the safety and tolerability of 6 months of adjuvant sunitinib and adjuvant valproic acid. (Cohort 1) V. To confirm the safety and tolerability of 12 months of adjuvant sunitinib. (Cohort 2) VI. To confirm the safety and tolerability of 12 months of adjuvant sunitinib and valproic acid. (Cohort 3)
TERTIARY OBJECTIVES:
I. To determine whether blood myeloid-derived suppressor cells (MDSCs) concentration and other inflammatory cytokines correlates with OS and RFS.
OUTLINE: Patients are assigned to 1 of 3 cohorts.
COHORT 1: Participants are randomized to 1 of 2 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.
COHORT 2: Patients receive sunitinib malate PO daily for 12 months in the absence of disease progression or unacceptable toxicity.
COHORT 3: Patients receive sunitinib malate PO daily and valproic acid PO daily for 12 months in the absence of disease progression or unacceptable toxicity.
