| Description | Real-world evidence about risdiplam therapy in adults with 5q spinal muscular atrophy (SMA) remains limited to outcomes in small cohorts, heterogeneous endpoints, and a short follow-up. We collected data of 59 adults with genetically confirmed 5q-SMA treated with risdiplam and analysed RULM, HFMSE, FVC % predicted, and ventilation status at baseline and at Month 6, 12, 24, and up to 36. The cohort comprised 59 adults (median age 28.5 years, range 17.0-59.2; 57.6% type 2, 33.9% type 3, and 8.5% type 1; 90.6% wheelchair users). During the follow-up period no patient lost motor function. RULM improved during the first 6 months and remained stable through 24-36 months. Over the follow-up, HFMSE showed a non-significant mean monthly increase of 0.05 points (P = 0.222), and RULM increased by 0.02 points per month (P = 0.079). No patient initiated ventilation during follow-up and forced vital capacity remained stable. In our adult population, including Type 1 survivors, risdiplam was associated with sustained upper-limb improvement, overall motor stability over 3 years, and a favourable respiratory trajectory without ventilation. Our findings indicate that stabilisation is a clinically meaningful target in advanced adult SMA patients. |
