Brief Summary
Chronic graft versus host disease (cGVHD) is a common complication of bone marrow or hematopoietic cell transplant from another person (allogeneic transplant). This study will determine if subjects with steroid dependent/refractory cGVHD can tolerate infusion of donor regulatory T cells and whether their cGVHD responds to the infusion.

Outcome Measures
Primary Outcomes (1)
The frequency of adverse events related to the donor Treg infusions (e.g., grade III-IV aGVHD by the modified Keystone criteria and grade 3 or higher infusional toxicities graded according to the CTCAE v. 4)
For infusion-related toxicities, recipients will be monitored for 1 hour after the Treg infusion. Additional toxicities which may occur during the first 28 days after the Treg infusions will count towards the assessment of safety and tolerability (DLT assessment) (e.g., development of aGVHD). Acute GVHD will be assessed using the modified Keystone criteria on Days 14, 28, 42, 56, 84 and 180 after the Treg infusion (or if the subject is exhibiting signs of aGVHD in-between study visits). Dose limiting toxicities are defined in Section 8. Only toxicities which occur during the first 28 days after the cell infusion will count towards the assessment of DLTs. A dose of Treg will be considered safe if DLTs occur in only 1/6 or 0/3 members of the cohort during the dose-escalation phase.
Up to day 180
Secondary Outcomes (5)
Change in absolute blood Treg levels
Baseline to day 42
Improvement in Failure Free Survival (FFS) over cGVHD
At day 180
Successful achievement of cGVHD partial response or Complete response by the NIH consensus criteria
Up to day 180
The ability to reduce steroid requirements to <0.25 mg/kg-day
At day 180
Change in >7 points on the Lee cGVHD Symptom scale relates to improvement in quality of life
Baseline to day 180
Study Arms (1)
Regulatory T Cells
EXPERIMENTALCohort 1 at 1x105 Treg cells/kg, Cohort 2 at 5x105 Treg cells/kg and Cohort 3 at 1.5x106 Treg cells/kg with an extension phase at the MTD (or maximum administered dose if the MTD is not reached).

Eligibility Criteria
You may qualify if:
- Steroid dependent/refractory cGVHD defined as:
- Steroid dependent disease: Persistent cGVHD manifestations requiring a glucocorticoid dose \>= prednisone 0.25 mg/kg/day (0.5 mg/kg orally \[po\] every other day) for at least 12 weeks
- Steroid refractory disease: Progressive cGVHD manifestations despite treatment with a glucocorticoid dose \>= prednisone 0.5 mg/kg/day (1 mg/kg po every other day) for at least 4 weeks
- Participants must be receiving systemic glucocorticoid therapy for cGVHD; all immunosuppressive therapy may include but not be limited to tacrolimus, sirolimus, CellCept, cyclosporine, and systemic corticosteroid must be at stable doses for 28 days prior to the first cell infusion
- Chronic GVHD manifestations that can be followed on physical or laboratory exam; these include but are not necessarily limited to:
- Skin changes
- Oral mucosa changes
- Bronchiolitis obliterans
- Ocular changes
- Karnofsky performance status \>= 60
- Serum creatinine =\< 2 mg/dL
- Absolute neutrophil count (ANC) \> 1 x 10\^9/L
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =\< 20 x upper limit of normal (ULN) or
- Total bilirubin =\< 10 x ULN
- Allogeneic hematopoietic cell transplant recipient
- +10 more criteria
You may not qualify if:
- Original transplant utilized an unrelated donor graft
- Uncontrolled infections that are not responsive to antimicrobial therapy
- Progressive malignant disease, including post-transplant lymphoproliferative disease unresponsive to therapy
- Second malignancy except for skin cancer within the last 5 years
- Received any investigational agent =\< 28 days before Treg infusions
- Received filgrastim (GCSF) treatment within one month of enrollment
- Received a donor lymphocyte infusion (DLI) or hematopoietic cell transplantation (HCT) within 3 months of enrollment
- DONOR: Evidence of active infection or viral hepatitis
- DONOR: HIV positive
- DONOR: Pregnant donor
