Developmental phase

Phase I,II


Assessment

Primary outcomes

Phase I: To determine the Maximum Tolerated Dose Level (MTD) of a 4 week course of IL-2 in patients with chronic GVHD
Phase IIa: To evaluate the 3-month Failure Free Survival (FFS)

Key secondary outcomes

1. Safety profiles of IL-2 administration during 12-week and subsequent extended study period
2. Clinical response based on NIH consensus criteria and steroid-dose reduction
3. Explanatory analysis of immune response in terms of increase in regulatory T cells

Interventions/Control_1

Patients will receive subcutaneous IL-2 at three dose levels (A: 3x10*4 units/m2/day, B: 1x10*5 units/m2/day, C: 3x10*5 units/m2/day) , daily for the first 4 weeks and 3 times a week for the next 8 weeks.

Patients with safe toxicity profile and clinical benefit could continue to receive subcutaneous IL-2 for the additional 36 weeks.
