OBJECTIVES: I. Determine the toxicity of total-body irradiation, anti-thymocyte globulin, and cyclophosphamide followed by syngeneic or autologous peripheral blood stem cell (PBSC) transplantation in patients with multiple sclerosis.
II. Determine the disease response of patients treated with this regimen. III. Determine the safety and efficacy of filgrastim (G-CSF) for PBSC mobilization in this patient population.
PROTOCOL OUTLINE: This is a multicenter study. Patients receive oral prednisone on days 0-10. Beginning on day 1, patients undergoing autologous peripheral blood stem cell (PBSC) transplantation receive filgrastim (G-CSF) subcutaneously daily until leukapheresis is completed. Leukapheresis begins on approximately day 4 and continues until adequate CD34+ PBSC are collected.
PBSC are collected from syngeneic donors in a similar manner. Patients undergo total-body irradiation twice daily on days -5 and -4. Patients receive cyclophosphamide IV on days -3 and -2 and anti-thymocyte globulin IV on days -5, -3, -1, 1, 3, and 5. Patients undergo autologous or syngeneic PBSC transplantation on day 0. Following PBSC transplantation, patients receive oral prednisone on days 7-30 and G-CSF IV daily beginning on day 0 and continuing until blood counts recover.
Patients are followed at 30, 80, and 90 days, monthly for 6 months, and then at 1 and 2 years.

The study is designed as a two arm randomized Phase II, multicenter trial comparing cyclophosphamide to anti-thymocyte globulin for Graft-versus-Host Disease (GVHD) prophylaxis in patients...
Cord blood transplantation (CBT) is associated with delayed hematopoietic recovery and graft failure. To overcome these problems, we conducted a prospective, multicenter phase II study of intrabone ma...
Administration of Filgrastim (rhG-CSF) (Neupogen®) in healthy donors to mobilize hematopoietic stem cells (HSC) is a widespread practice in adults. Application of peripheral blood stem cell (PBSC) co...

Safety and efficacy of alternating treatment with EP2006, a filgrastim biosimilar, and reference filgrastim: a phase 3, randomised, double-blind clinical study in the prevention of severe neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy.
In 2015, the biosimilar filgrastim EP2006 became the first biosimilar approved by the US Food and Drug Administration (FDA) for commercial use in the United States, marketed as Zarxio®. This phase 3 ...
OBJECTIVE To investigate mechanisms by which anti-inflammatory doses of orally administered intermediate-acting glucocorticoids (prednisone) could predispose dogs to progression of heart disease or co...
Immunizing agent containing IMMUNOGLOBULIN G anti-Rho(D) used for preventing Rh immunization in Rh-negative individuals exposed to Rh-positive red blood cells.
A synthetic anti-inflammatory glucocorticoid derived from CORTISONE. It is biologically inert and converted to PREDNISOLONE in the liver.
N(2)-((1-(N(2)-L-Threonyl)-L-lysyl)-L-prolyl)-L-arginine. A tetrapeptide produced in the spleen by enzymatic cleavage of a leukophilic gamma-globulin. It stimulates the phagocytic activity of blood polymorphonuclear leukocytes and neutrophils in particular. The peptide is located in the Fd fragment of the gamma-globulin molecule.
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
Spinal Cord Disorders
The spinal cord is a bundle of nerves that runs down the middle of the back which carry signals back and forth between the body and brain. It is protected by vertebrae, which are the bone disks that make up the spine. An accident that damages the verte...
