A Randomized Phase II Study of Sequential Biotherapy With Aflibercept and High Dose IL-2 Versus High Dose IL-2 Alone in Patients With Inoperable Stage III or Stage IV Melanoma: Efficacy and Biomarker Study


I. Test the hypothesis that combination biotherapy with aflibercept and HD IL-2 will improve
the progression-free survival compared to HD IL-2 alone.


I. Evaluate the response rate (CR + PR) of aflibercept and HD IL-2 as assessed by RECIST
criteria version 1.1 and compare to HD IL-2 alone.

II. Evaluate the toxicities and tolerance of combination biotherapy with aflibercept and HD
IL-2 and maintenance aflibercept alone in this patient population and compare to HD-IL2

III. Test the hypotheses related to the laboratory correlative studies. IV. Evaluate the
overall survival of patients treated with aflibercept and HD IL-2 and HD IL-2 alone.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive aflibercept IV over at least 1 hour in weeks 1, 3, 5, and 7 (and in
week -1 of course 1 only) and high-dose aldesleukin IV over 15 minutes every 8 hours for 5
days in weeks 1 and 3. Treatment repeats every 8 weeks for 3 courses in the absence of
disease progression or unacceptable toxicity. Patients then receive maintenance therapy
comprising aflibercept IV on day 1. Treatment repeats every 14 days in the absence of
disease progression or unacceptable toxicity.

ARM II: Patients receive high-dose aldesleukin IV over 15 minutes every 8 hours for 5 days
in weeks 1 and 3. Treatment repeats every 4 weeks for up to 3 courses in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3-4 months for 5 years.
