Introduction/Aims Risdiplam is the newest available treatment for patients with spinal muscular atrophy (SMA). There is little information on its use in adults. We present the clinical experience of adults with SMA treated with risdiplam through the Early Access to Medicines Scheme (EAMS) in Northern Ireland. Methods All adults with Type 2 SMA attending the regional neuromuscular clinic were offered risdiplam treatment. Patients had assessments of respiratory function, the Epworth Sleepiness Scale (ESS), Quality of Life Measure for People with Slowly Progressive and Genetic Neuromuscular Disease (QOLM), and Egen Klassifikation 2 (EK2) every 3 mo and the Revised Upper Limb Module for SMA (RULM) at baseline and 6 mo. All assessments other than the RULM were carried out virtually. Results Six of seven patients who were offered risdiplam consented to treatment through the EAMS (five female, one male, mean age 33.7 y). It was generally well tolerated other than skin photosensitivity in all patients. All patients remained on therapy at 9 mo. All reported meaningful improvements in overall strength, sense of wellbeing, and speech quality. There was no change in respiratory function, daytime hypersomnolence, or upper limb function (all p > .05). There was improvement in the QOLM (p = .027) and EK2 (p = .009). Discussion Our study raises hopes that risdiplam may be efficacious in adults; however, more systematic studies in larger cohorts are needed before drawing any definitive conclusions. This study also demonstrated the feasibility of virtual assessments.
