简要总结
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.
详细描述
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: Subjects may be re-screened if they fail to meet inclusion criteria on initial evaluation
