Summary

This phase II trial studies how well giving cyclophosphamide and anti-thymocyte globulin together followed by peripheral blood stem cell transplant (PBSCT) and mycophenolate mofetil works in treating patients with systemic scleroderma (SSc). Stem cells are collected from the patient's blood and stored prior to treatment. To store the stem cells patients are given colony-stimulating factors, such as filgrastim (G-CSF) or chemotherapy (cyclophosphamide) to help stem cells move from the bone marrow to the blood so they can be collected and stored. After storage, patients are then given high-dose chemotherapy, cyclophosphamide, and immunosuppression with anti-thymocyte globulin to suppress the immune system to prepare for the transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and immunosuppression. After the stem cells have "engrafted" and have matured enough to support the immune system at approximately 2-3 months, patients are given a medication called mycophenolate mofetil (MMF) or Myfortic. This medication is given to prevent worsening or reactivation of SSc and is referred to as maintenance therapy.

Detailed description: PRIMARY OBJECTIVES: I. To evaluate the safety and potential efficacy of high-dose immunosuppressive therapy (HDIT) followed by autologous hematopoietic cell transplantation (HCT) (without cluster of differentiation [CD]34-selection) and maintenance therapy with mycophenolate mofetil (MMF) in systemic scleroderma (SSc) patients by evaluating the effects on event-free survival (EFS) at 5 years post-transplant. SECONDARY OBJECTIVES: I. To evaluate safety of HDIT followed by autologous HCT as determined by regimen-related toxicities, infectious complications, treatment-related mortality, overall total mortality, and time to engraftment. II. To evaluate treatment effect on disease activation/progression. III. To evaluate health-related quality of life (HRQOL) using Short Form 36 (SF-36), the St. George's Respiratory Questionnaire (SGRQ), the modified scleroderma health assessment questionnaire (SHAQ), and PROMIS version (v) 1. 0 measures. IV. To assess work productivity (Work Productivity Survey) and health care utilization (using University of California San-Diego [UCSD] healthcare utilization). OUTLINE: STEM CELL MOBILIZATION AND PREPARATION: Patients receive filgrastim subcutaneously (SC) on mobilization days 1-4 followed by apheresis until a target dose of CD34+ cells >= 2. 5 x 10^6/kg are collected. Patients difficult to mobilize with filgrastim alone receive cyclophosphamide intravenously (IV) or *plerixafor subcutaneously (SC) on mobilization days 1-2 and filgrastim SC on mobilization days 5-7.

HDIT CONDITIONING: Patients receive high-dose cyclophosphamide IV over 1-2 hours on days - 5

to - 2 and anti-thymocyte globulin IV on days -5, -3, -1, 1, 3, and 5.

TRANSPLANTATION: Patients undergo autologous PBSCT on day 0. MAINTENANCE THERAPY: Beginning 2-3 months after transplant, patients receive mycophenolate mofetil orally (PO) twice daily (BID) for 2 years. NOTE: *Plerixafor is an alternative to the cyclophosphamide based mobilization. After completion of study treatment, patients are followed at 1 month, weeks 12 and 26, and then annually for 5 years.

Criteria:

Inclusion Criteria:

- Patients with SSc as defined by the American College of Rheumatology with diffuse

cutaneous disease (except Group 5) at risk of disease progression

- Patients must have failed a prior >= 4-month course of either MMF/Myfortic or

cyclophosphamide before being eligible for the study (determined at >= 1 week before start of mobilization); "failure" is defined as evidence of disease progression or absence of improvement; the response prior to MMF of cyclophosphamide will be assessed by the participating site study rheumatologist

- Patients must meet eligibility in at least 1 of the following 6 groups:

- GROUP 1:

- Patients must have 1) both a and b below; and 2) either c, or d

- a) Diffuse cutaneous scleroderma as defined by skin thickening proximal to

the elbows and knees and/or involving the torso in addition to distal extremity involvement; a skin score will be obtained but not used to determine eligibility

(FVC) < 80% or hemoglobin-adjusted diffusing capacity for carbon monoxide (DLCO) < 70% of predicted AND evidence of alveolitis by high-resolution chest computed tomography (CT) scan and/or by bronchoalveolar lavage (BAL) (if high resolution computed tomography [HRCT] fails to show ground glass, then BAL for diagnosis of alveolitis must be confirmed); alveolitis by BAL cell count will be defined based on a BAL cell differential count (> 3% neutrophils and/or > 2% eosinophils) from any lavaged lobe

- d) History of SSc-related renal disease that may not be active at the time

of screening; stable serum creatinine must be documented for a minimum of 3 months post-renal crisis at the time of the baseline visit; history of scleroderma hypertensive renal crisis is included in this criterion and is defined as follows:

- History of new-onset hypertension based on any of the following

(measurements must be repeated and confirmed at least 2 hours apart within 3 days of first event-associated observation, with a change from baseline):

(RBC)s/hematopoietic-promoting factor (HPF) (without menstruation)

- Thrombocytopenia: < 100,000 platelets/mm^3

- Hemolysis: by blood smear or increased reticulocyte count

- The above definition of SSc hypertensive renal crisis is independent

of whether concomitant anti-hypertensive medications are used

- Subjects who present with solely skin and renal disease in the absence

of other organ involvement, except classic SSc renal crisis as described above and including non-hypertensive renal crisis, must see a nephrologist to confirm that their renal disease is secondary to only SSc

- Note: Subjects may be re-screened if they fail to meet inclusion

criteria on initial evaluation

count (> 3% neutrophils and/or > 2% eosinophils) from any lavaged lobe

- GROUP 6: Progressive gastrointestinal disease as defined by all of the following

items:

- Disease duration of scleroderma =< 2 years.
