The OMS/DES study is a multinational European Trial for Children with the Opsoclonus Myoclonus Syndrome / Dancing Eye Syndrome.
This trial brought on the way by specialists of the EPNS (European Paediatric Neurology Society), the GPOH (Gesellschaft für Pädiatrische Hematologic und Oncologie) and the SIOPEN (SIOP (International Society Oncology Pediatric) Europe Neuroblastoma).
This protocol will investigate an escalating treatment schedule starting with a corticosteroid standard treatment with dexamethasone pulses (first step), which is followed, if response has been inadequate after 3 months of treatment, by the addition of CP (second step) and, if still no sufficient improvement, by the replacement of CP by Rituximab (third step). Treatment intensification is decided on the basis of standardized scoring of OMS/DES severity.
