A Clinical Trial of Dantrolene Sodium in Pediatric and Adult Patients With Wolfram Syndrome

Summary

Wolfram syndrome is a rare genetic disorder characterized by juvenile-onset diabetes mellitus, diabetes insipidus, optic nerve atrophy, hearing loss, and neurodegeneration. The purpose of this study is to assess the safety and tolerability of dantrolene sodium in patients with Wolfram syndrome. In addition, we will assess the efficacy of dantrolene sodium on the cardinal manifestations of Wolfram syndrome, including visual acuity, remaining beta cell functions, and neurological functions. There is a screening period up to 56 days, a 6-month treatment period with an optional extension phase up to 24 months, and a 4-week safety follow-up period. Study assessments include medical \& medication history, physical exams, neurological exams, eye exams, endocrine exams, vital signs, height, weight, electrocardiograms, blood and urine tests, pregnancy test if applicable, and questionnaires.
