Filter by:This study is designed to treat your disease with an autologous stem cell transplant using a regimen of immune suppressant drugs and chemotherapy to reset your immune system and to determine if your disease will go into long-term remission.
Neuromyelitis Optica Spectrum Disorder (NMOSD) is a severe inflammatory disease of the central nervous system characterized by relapsing optic neuritis and longitudinal extensive transverse myelitis. The specific autoantibody against aquaporin 4 (AQP4-ab) has been suggested to contribute to the pathogenesis of the disease. Peripheral blood plasma cells are a major source of AQP4-ab. Previous studies have observed increased IL-6 levels in serum and cerebrospinal fluid of patients with NMOSD, particularly during relapses. Exogenous interleukin (IL)-6 promotes the survival of plasma cells and their production of AQP4-ab in vitro. And blockade of IL-6 receptor signaling by an anti-IL-6 receptor antibody reduces the survival of plasma cells in vitro. Tocilizumab (ACTEMRA®), a humanized monoclonal antibody against the IL-6 receptor, has shown beneficial clinical effects in some patients with NMOSD when concomitant immunosuppressive medications were administered. However, the long-lasting biological effects of preceding immunotherapies such as rituximab might overlap with the subsequent tocilizumab therapy. To reduce the side effects of concomitant treatments to large extent and verify the beneficial effects of tocilizumab, we evaluate the safety and efficacy of tocilizumab as monotherapy in patients with NMOSD.
Neuromyelitis optica (NMO) is a demyelinating and degenerative disorder of the central nervous system affecting vision and brain and spinal cord function which leads to accumulating disability with a 5 year-mortality of approximately 30%. Survivors are typically left with severe morbidity secondary to blindness, quadriparesis and respiratory failure. No agent has been found to be highly effective in halting disease activity.Based on recent outcomes of Multipotent mesenchymal stromal cells in autoimmune diseases including multiple sclerosis, and based on the mechanisms of neuromyelitis optica, the investigators anticipate that mesenchymal stem cells transplantation may provide lasting disease stability for neuromyelitis optica patients.
The purpose of this study is to determine if the drug eculizumab reduces the attack rate and improves outcome in patients with neuromyelitis optica.
This study is designed to examine whether treating Devic's disease patients with high dose cyclophosphamide together with rabbit antithymocyte globulin (rATG)/rituximab (drugs which reduce the function of the immune system), followed by return of previously collected patient's stem cells will result in improvement in Devic's disease. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the intense chemotherapy is to destroy the cells in patient's immune system, which may be causing his/her disease. The purpose of the stem cell infusion is to produce a normal immune system that will no longer attack patient's body. The purpose of study is to examine the safety and efficacy of this treatment. The drugs used in this study treatment are drugs for commonly used for immune suppression.
