Safety of Onasemnogene Abeparvovec for Patients With Spinal Muscular Atrophy 8.5 kg or Heavier in a Global Managed Access Program
Spinal muscular atrophy is a rare, neurodegenerative disorder caused by biallelic deletions in the survival motor neuron (SMN1) gene. Onasemnogene abeparvovec is a one-time, intravenous gene replacement therapy designed to deliver the SMN1 transgene. Although available in many geographies, it is not...

The Global Managed Access Program (GMAP) expanded treatment access to patients in countries where treatment was not approved. Previous onasemnogene abeparvovec clinical trials included patients with body weight <8.5 kg. Through GMAP, children weighing ≥8.5 kg received onasemnogene abeparvovec. We describe safety data for heavier patients in GMAP.
GMAP records were reviewed to identify patients weighing ≥8.5 kg at onasemnogene abeparvovec dosing. To obtain corresponding adverse event (AE) data, the Novartis ARGUS safety database was searched using patient identification numbers and birth dates/dosing dates for any reported AE for GMAP patients.
As of September 2, 2021, 102 patients weighing ≥8.5 kg at time of dosing were identified. Fifty-four (53%) had one or more reported AEs. Three patients were reported to be deceased. All three deaths were assessed to be secondary to acute respiratory events. Most (62%) AEs were non-serious. The most frequently reported AEs included increases in hepatic laboratory values, decreased platelets and thrombocytopenia, pyrexia, vomiting, and decreased appetite.
Safety findings for patients weighing ≥8.5 kg administered onasemnogene abeparvovec through GMAP were consistent with those described in clinical trials and included hepatotoxicity, thrombotic microangiopathy, and thrombocytopenia.</description><identifier>ISSN: 0887-8994</identifier><identifier>EISSN: 1873-5150</identifier><identifier>DOI: 10.1016/j.pediatrneurol.2022.05.001</identifier><identifier>PMID: 35605311</identifier><language>eng</language><publisher>United States: Elsevier Inc</publisher><subject>Adverse events ; Gene therapy ; Managed access program ; Neuromuscular disease ; Onasemnogene abeparvovec ; Pediatrics ; Safety ; Spinal muscular atrophy</subject><ispartof>Pediatric neurology, 2022-07, Vol.132, p.27-32</ispartof><rights>2022 The Author(s)</rights><rights>Copyright © 2022 The Author(s).
