Opsoclonus-myoclonus ataxia syndrome (OMS) is a rare immune mediated paraneoplastic syndrome that occurs in approximately 2 to 3% of children with neuroblastoma. Children with neuroblastoma associated opsoclonus-myoclonus tend to have a favorable prognosis from the standpoint of the cure of their cancer. Unfortunately,approximately two-thirds of this subgroup of patients are left with long term sequellae of the syndrome, including residual symptoms of opsoclonus, myoclonus, ataxia, learning difficulties and disturbance of sleep and mood.
Multiple lines of evidence indicate an immune mechanism to this rare disorder. This includes occurence of OMS in the post-infectious state, aggressive lymphocytic infiltration of the tumor in children with OMS, and documented responses to therapries that act through suppression of the immune system.
The current study utilizes four weekly doses of anti-CD 20 antibody (rituximab) to treat children with refractory OMS. Refractory disease is defined as continued symptoms of OMS despite surgical resection of the tumor and a minimum of one month of steroid therapy.
All patients have baseline OMS evaluation and detailed neurocognitive testing with all studies being repeated at the completion of the four weekly infusions. OMS testing is repeated at Month 3. OMS testing and detailed neurocognitive testing is conducted at 6 months intervals until 2 years from the initial infusion.
The goal of the study is to utilize this novel therapy to improve long term neurologic and neurodevelopmental outcome in children with refratory neuroblastoma associated opsoclonus-myoclonus.
