Clinical Trial Summary

The purpose of this research study is to determine the safety of IL-2 and the highest dose of this drug that can be given safely to people with chronic graft versus host disease (GVHD). Chronic GVHD is a medical condition that may occur after patients receive a bone marrow, stem cell or cord blood transplant. The donor's immune system may recognize their body (the host) as foreign and attempt to "reject" it. Traditional standard therapy to treat chronic GVHD is prednisone (steroids). Treatment options are limited, and it is thought that IL-2 may help to control chronic GVHD.

Description:

• IL-2 will be given daily through an injection under the skin for a period of 8 weeks. To determine the highest safest dose of IL-2, the dose participants receive will increase as lower doses are determined to be safe. There will be three dose levels.

• Participants will be seen periodically while they are receiving IL-2. Physical exams and blood tests will be performed weekly for the first two weeks and then every other week until week 8.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Maximum Tolerated Dose and Toxicity Profile of an 8 Week Course of IL-2 in Patients With cGVHD and an Inadequate Response to Steroids.	Three dose levels were evaluated to determine the maximally tolerated dose (MTD): Dose level A: 0.3 x 10^6 IU/m^2/day Dose level B: 1.0 x 10^6 IU/m^2/day Dose level C: 3.0 x 10^6 IU/m^2/day Once the MTD (dose level B) was established, an additional 10 participants were enrolled at this dose.	Participants were assessed for toxicities at mandatory study follow-up visits during the 8 week course of study therapy and four weeks post therapy
Secondary	The Number of Participants Who Tolerated at Least 6 Weeks of Subcutaneous Low Dose IL-2.	Feasibility: the number of participants who tolerated at least 6 weeks of therapy, and were thus evaluable for response. Efficacy: chronic GVHD response per NIH consensus criteria in evaluable patients.; A complete response was defined as resolution of all reversible chronic GVHD-associated manifestations, a partial response as an improvement of 50% or more on the organ-specific chronic GVHD scale without progression at other organs or sites, progressive disease as an increase of 25% or more on the organ specific chronic GVHD scale, and stable disease as an improvement of less than 50% or increase of less than 25%. Please refer to the Supplementary Appendix in our published report (Koreth et al, NEJM 2011) for further details.	Participants were assessed for toxicities at mandatory study follow-up visits during the 8 week course of study therapy and four weeks post therapy. cGVHD was assessed at Weeks 8 and 12
Secondary	CD3+T, CD4+T (Including Regulatory CD4+T Cells (Treg) and Conventional CD4+T Cells (Tcon)), CD8+T, NK, NKT and B Cell Counts.	Changes in the above immune cell populations (CD3+T, CD4+T (including CD4+Treg and CD4+Tcon), CD8+T, NK, NKT and B cell counts were measured at study appointments during the 8-week IL-2 treatment and four weeks post study therapy.; All study participants (n=28) with a sample available were reported in the data table.; Immune outcome data cannot be meaningfully rendered in the template provided, owing to complexity. The tables below only represent a general overview of the data. Please refer to figure 2 in our published report (Koreth et al, NEJM 2011).	Immunological samples taken at study appointments during the 12 week protocol schedule
Secondary	Treg Cell:Tcon Cell Ratio	Changes in the ratio of the CD4+ regulatory T cell (Treg) and CD4+ conventional T cell (Tcon) counts were measured at study appointments during the 8-week IL-2 treatment and four weeks post study therapy.; All study participants (n=28) with a sample available were reported in the data table.; Immune outcome data cannot be meaningfully rendered in the template provided, owing to complexity.
