Progression-free SurvivalPrimary· The time from the date of randomization until date of progression, death, or recurrence, assessed up to 5 years
Estimated using the product-limit method of Kaplan and Meier. 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.

Progression-free Survival for Patients With High Vascular Endothelial Growth Factor (VEGF) LevelsSecondary· Up to 5 years
Estimated using the product-limit method of Kaplan and Meier. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), 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. Median baseline measure for VEGF were used as the cut point for "low" vs "high" VEGF groups.

This randomized phase II trial studies how well aldesleukin with or without ziv-aflibercept works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Aldesleukin may stimulate the white blood cells to kill cancer. Ziv-aflibercept may stop the growth of melanoma by blocking blood flow to the tumor. It is not yet known whether aldesleukin is more effective with or without ziv-aflibercept in treating melanoma.
