Phase II Trial of (IL-2) With Priming and (GM-CSF) in Patients With Advanced Melanoma

The primary objectives of this phase II multicenter trial are to:

Determine the 1 and 2-year survival of patients treated according to protocol. Assess the safety and toxicity of this regimen in this patient population.

The secondary objectives are to:

Determine the freedom from progression (FFP). Measure the response rate (RR). Obtain immunological data from the use of this regimen in vivo (as separate project: Moffitt?).

The proposed study is a multicenter phase II trial of HD-IL-2 in combination with GM-CSF. GM-CSF will be started 7 days before day 1 of HD-IL-2 and will be continued for 4 weeks to day 28, encompassing two cycles of HD-IL2. The first 9 patients will be closely monitored for unexpected toxicity.
