Brief 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

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.

The Number of Participants Who Completed ALL Health Care Utilization as Assessed by UCSD Healthcare Utilization SurveysFrom baseline to 5 years

UCSD healthcare utilization is a self-report instrument that asks the patient about outpatient and inpatient visits, prescription and non-prescription medications, any surgeries, and major medical expenses during the last 3 months.

The Median SHAQ ScoreBaseline to year 4

Scleroderma Health Assessment Questionnaire (SHAQ) is a self reported questionnaire with 8 domains including the following scales: pain, patient global assessment, vascular digital ulcers, lung involvement, and gastrointestinal involvement. The SHAQ is a quality of life measure. Each question is scored from 0 (defined as without difficulty), to 3 (defined as unable to do). Some domains are visual analog scales that are measured first and then changed to the 0-3 scale. The individual scores are combined and divided by 8. A higher score indicates worse functionality and changes in the SHAQ is measured as medium change from baseline. The reported medium change can range from -3 to 3. A negative medium change indicates a better outcome.

The Number of Participants Who Completed ALL Work Productivity Survey (WPS)Baseline to year 5

The first question assesses employment status, type of job for the employed (non-manual, manual or mixed manual/non-manual) and the status of those unemployed (homemaker, retired, student, unable to work due to SSc, unable to work due to non-SSc health problems, or other, i.e. volunteer). The next 3 questions apply only to employed patients and assess absenteeism (full days of work missed due to SSc), presenteeism (days with work productivity reduced by greater than or equal to 50%), and how much SSc interfered with work productivity on a scale of 0-10.
