Detailed Description:

PROTOCOL OUTLINE: This is a randomized, open-label study. Patients are randomized to receive polyethylene-glycol-conjugated interleukin 2 (PEG-IL-2) or placebo.

Patients receive PEG-IL-2 or placebo by subcutaneous injection weekly for 18 months. Patients maintain a daily diary for 24 months.

Patients are followed every 4 months for 2 years.
