Allogeneic Hematopoietic Cell Transplantation After Nonmyeloablative Conditioning for Patients With Severe Systemic Sclerosis
The purpose of the study is to examine the safety and effectiveness of a reduced intensity conditioning regimen and allogeneic bone marrow transplant for people with systemic sclerosis. In an allogeneic bone marrow transplant procedure, bone marrow is taken from a healthy donor and transplanted into the patient. Bone marrow can be donated by a family member or an unrelated donor who is a complete tissue type match.
Participants will receive the chemotherapy and low dose radiation conditioning regimen consisting of the following: Fludarabine will be given intravenously for 5 days. Cyclophosphamide will be given intravenously on the first and second day. After completing the fludarabine and cyclophosphamide, patients will receive a single low dose of total body irradiation. The next day, patients will receive the allogeneic bone marrow transplant. On the third and fourth day after the transplant, patients will receive high dose intravenous cyclophosphamide. This is given to help prevent two complications: (1) graft rejection, which occurs when the body's immune system rejects the donor bone marrow, and (2) graft-versus-host disease (GVHD), which is when the donor immune cells attack the patient's normal tissues. On the fifth day after the transplant, patients will start receiving two additional medications: tacrolimus and mycophenolic acid (MPA, Myfortic), to help prevent GVHD. Patients will receive mycophenolic acid for about 5 weeks and tacrolimus for about 6 months. Also beginning on the fifth day after the transplant, patients will receive daily injections of a growth factor called granulocyte-colony stimulating factor (G-CSF), which is a protein that increases the white blood cell count; G-CSF will be continued until the patient's white blood cell count has returned to normal levels.
Patients will remain closely monitored either in the outpatient clinic setting or in the hospital for approximately 2-3 months after the transplant, but possibly longer if there are complications. Follow-up study visits will occur at 6 months and then at 1, 2, 3, 4, and 5 years after the transplant. Study researchers will keep track of the patient's medical condition after leaving the transplant center by phone calls or mailings to patients and their doctors once a year for the rest of the study participants' lives.

- Event-free survival (EFS) [ Time Frame: 2 years ] [ Designated as safety issue: No ]The events will be defined as any one of the following: death; respiratory failure; renal failure, as defined by chronic dialysis > or = 6 months or kidney transplantation; occurrence of cardiomyopathy, confirmed by clinical CHF (New York Class III or IV) or LVEF < 30% by echocardiogram, sustained for at least 3 months despite therapy; organ dysfunction specific events must be documented on at least two occasions > or = 3 months apart, or sustained for a 3-month period (documented from the first occurrence).
- EFS [ Time Frame: 5 years ] [ Designated as safety issue: No ]
- Overall survival [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]Event is defined as death due to any cause.
- Treatment-related mortality [ Time Frame: From time of transplant to 5 years ] [ Designated as safety issue: No ]Defined as death occurring at any time after start of allogeneic HCT and definitely or probably resulting from treatment given in the study and not associated with disease progression.
- Regimen-related toxicity (greater than or equal to Grade III) as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 [ Time Frame: Up to 5 years ] [ Designated as safety issue: Yes ]
- Incidence of definite and probable viral, fungal, and bacterial infections in each patient [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
- Quality of life as assessed by the Modified Scleroderma Health Assessment Questionnaire (SHAQ) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]The questionnaire includes eight general activity domains, derived from the Health Assessment Questionnaire Disability Index (HAQDI): dressing, arising, eating, walking, hygiene, reach, grip, and common daily activities; and 5 overall disease specific domains that include: Raynaud's phenomenon, finger ulcers, breathing, and intestinal problems. Each domain is composed of questions with visual analog scales from 0 to 100. Higher scores represent more disability.
- Quality of life as assessed by the Medical Outcome Short Form (36) Health Survey instrument (SF-36) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]The Medical Outcome Short Form (36) Health Survey instrument (SF-36) is a general assessment of health quality of life with eight components: physical functioning, role limitations due to physical health, pain index, general health perceptions, vitality, social functioning, role limitations due to emotional problems and Mental Health Index. Each domain is positively scored, indicating that higher scores are associated with positive outcome.
- Skin score and pulmonary function tests [ Time Frame: Up to 5 years post-transplant ] [ Designated as safety issue: No ]
- Incidence of graft rejection [ Time Frame: Up to day +56 ] [ Designated as safety issue: No ]Engraftment is defined as achieving > 5% donor peripheral blood T cell chimerism by Day 56 after HCT. Primary graft failure is defined as a donor peripheral blood T cell chimerism peak of < 5% by Day 56 post-HCT. Methodological requirements for chimerism are as defined by institutional standard of practice. Secondary Graft Failure is defined as documented engraftment followed by loss of the graft with donor peripheral blood T cell chimerism < 5% as demonstrated by a chimerism assay
- Incidence and severity of graft-versus-host disease (GVHD) [ Time Frame: Up to 5 years post-transplant ] [ Designated as safety issue: No ]The grading of acute and chronic GVHD will follow previously published guidelines and according to institutional standard of practice but will also include capture of symptoms and characterization of alternative causes. The highest level of organ abnormalities, the etiologies contributing to the abnormalities and biopsy results pertaining to GVHD will be identified. Since both GVHD and SSc involve the skin and the gastrointestinal tract, all diagnostic biopsies of these organs will be centrally reviewed by a study pathologist.
- Incidence of disease-modifying antirheumatic drugs (DMARDs) initiated post transplant to modify disease [ Time Frame: Up to 5 years post-transplant ] [ Designated as safety issue: No ]
