Effectiveness of Rituximab in Pediatric OMS Patients.
The purpose of this study is to reduce the symptoms of OMS by testing rituximab (Rituxan®), to remove B lymphocytes that make antibodies and trigger brain inflammation. Evidence suggests that autoimmune brain inflammation causes the symptoms of OMS. This study of blood and spinal fluid intends to find out what effect rituximab has on OMS and on the spinal fluid B-cells.
Rituximab targets and destroys B-cells, which make antibodies that can attack the brain and cause may OMS. It is infused through a vein over a period of several hours. Rituximab has been used widely and studied extensively since its approval in 1997 by the U.S. Food and Drug Administration (FDA) for non-Hodgkin's B-cell Lymphoma (NHL). Today, more than 300,000 patients have received rituximab, and it is part of more than 200 completed, ongoing, or planned clinical trials. Rituximab is not FDA-approved for OMS.
|Opsoclonus-myoclonus Syndrome Opsoclonus Myoclonus Ataxia||Drug: rituximab||Phase 1 Phase 2|
|Study Design:||Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase I Clinical Trial of Rituximab for Pediatric Opsoclonus-Myoclonus Syndrome|
- Determine the effectiveness & selectivity of rituximab at depleting CSF B-cells in OMS with intrathecal B-cell expansion. This requires CSF & blood lympocyte immunophenotyping prior to the first infusion & intervals for 1 year after the final infusion.
- Evaluate the clinical efficacy & safety of rituximab by clinical assessments, scoring of videotapes for neurological severity, and various blood tests prior to the first infusion and then at one, three, six, and twelve months post the final infusion.
