Brief Summary:
This research study is a Phase I clinical trial, which tests the safety of an investigational combination of IL-2 plus donor anti-inflammatory Treg cells and also tries to define the appropriate dose of the investigational combination of IL-2 plus donor anti-inflammatory Treg cells to use for further studies. IL-2 is involved with cell signaling and regulation of white blood cells (WBCs). WBCs are part of the immune system. Treg cells are also part of the immune system; they are involved with anti-inflammatory responses. "Investigational" means that the combination of IL-2 and anti-inflammatory Treg cell infusion is being studied. It also means that the FDA (U.S. Food and Drug Administration) has not approved the combination of IL-2 and anti-inflammatory Treg cell infusion for use in people with cGVHD.
Chronic GVHD is a medical condition that may occur after you have received your bone marrow, stem cell or cord blood transplant from a donor. The donor's immune system may recognize your body (the host) as foreign and attempt to 'reject' it. This process is known as graft-versus-host disease.
Traditional standard therapy to treat cGVHD is prednisone (steroids). Participants on this trial have not responded to steroid therapy. The investigators are looking to assess the safety and optimal dose for the combination of IL-2 plus donor anti-inflammatory Treg cells, that may help control cGVHD by stopping the donor's immune system from 'rejecting' your body.

Detailed Description:
After the screening procedures confirm that you are eligible to participate in the research study: If you take part in this research study, you (and your donor) will have the following tests and procedures:
Donor Lymphocytes Collection: Lymphocytes are a type of white blood cell involved with the immune system. Your original marrow/stem cell donor will undergo one white blood cell collection procedures called leukapheresis. Blood from the vein in one arm will be circulated through a special machine to remove the white blood cells, and the rest of the blood will be returned to the donor's other arm. The cells collected from the leukapheresis will be sent to the laboratory where the amount of white blood cells collected will be measured. A sample will be removed for study testing, and the remaining lymphocytes will be set-aside for infusion.
Donor Lymphocyte Processing: Once the lymphocytes are collected from your donor, the CliniMACS System device will enrich (preferentially select) the number of Treg cells. Samples will be taken before and after processing by the CliniMACS System to examine the cells. After completing the necessary safety tests, the Treg-enriched donor lymphocyte cells will be ready for administration.
Donor Cellular Infusion (DCI): The Treg-enriched donor lymphocytes will be infused through an intravenous (I.V.) catheter over approximately 5-10 minutes. Prior to the infusion, you will receive Tylenol and Benadryl to prevent transfusion related reactions. You will be observed for about 1 hour after the infusion. The total anticipated time you will spend in the clinic is approximately 2 hours.
Since the investigators are looking for the highest one-time dose of the anti-inflammatory donor cells that can be administered safely in combination with IL-2 without severe or unmanageable side effects in participants that have cGVHD, not everyone who participates in this research study will receive the same dose of the donor cells. The cell dose you get will depend on the number of participants who have been enrolled in the study before you and how well they have tolerated their cell doses.
Study Drug: You will give yourself or be given IL-2 daily through an injection under your skin. You will do this once every day for 8 weeks, starting from the day of donor Treg cell infusion. You will then have 4 weeks off of IL-2.
IL-2 will be provided in single-use (one-time only) syringes to be refrigerated at home at 36 - 46°F (2 - 8°C).
During the first 6 weeks of IL-2, you will continue to take steroids and other immune suppressing medications without changing the dose your doctor has set for you while you are on IL-2. After 6 weeks of IL-2 therapy, your doctor may reduce the amount of steroids you take.
If your cGVHD improves after 8 weeks on IL-2, you may have the option of continuing extended-duration therapy. Extended-duration therapy is daily IL-2 treatment starting at the end-of-study visit after week 12. Your doctor will discuss this option with you. If you continue with extended-duration IL-2 therapy after completing the week 12 evaluation, you will be assessed on the following schedule:
* Clinic visits for evaluation of toxicity and clinical benefit approximately every 4 weeks
* Immunologic assays approximately every 8 weeks. Immunologic assays will measure the effect of IL-2 on immune cells.
Drug Diary: Each day for the first 8 weeks you take IL-2 and each day during extend-duration IL-2 (if applicable), you will be asked to document, in a drug diary, when you took the drug and where you injected it. The diary will also include special instructions for taking the study drug(s). The diary will also ask if the entire syringe was injected, and if there were other issues related to IL-2. You will be asked to return your drug diary to clinic every 14 days while you receive IL-2. If you continue taking IL-2 in the extend-duration portion, you will return your drug diary every 8 weeks (at your clinic visit).
Chronic GVHD Assessments: While you are on study, a member of the study team will examine you to evaluate your cGVHD. These assessments may include examination of your skin, joints/muscles, eyes, mouth, lungs and gastrointestinal system (for example, whether you have experienced any nausea, vomiting, diarrhea, difficulty swallowing). The investigators will also look at the range of motion of different body parts (for example, your arms).
