详细说明
- 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.

实验性的:Interleukin-2
Interleukin-2 (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: Dose Level -A 0.3 x 106 (IU/m2/d) Dose Level -B 1 x 106 (IU/m2/d) Dose Level-C 3 x 106 (IU/m2/d) |
Dose will vary depending upon when participant enters the trial: Given as a daily injection under the skin for 8 weeks.

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.
大体时间:Participants were assessed for toxicities at mandatory study follow-up visits during the 8 week course of study therapy and four weeks post therapy
|
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. |

The Number of Participants Who Tolerated at Least 6 Weeks of Subcutaneous Low Dose IL-2.
大体时间: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
|
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. |

CD3+T, CD4+T (Including Regulatory CD4+T Cells (Treg) and Conventional CD4+T Cells (Tcon)), CD8+T, NK, NKT and B Cell Counts.
大体时间:Immunological samples taken at study appointments during the 12 week protocol schedule

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). |
