Early life safety profiling of gene therapy for spinal muscular atrophy.

ABSTRACT: The present study examines the safety profile of intravenous onasemnogene abeparvovec gene therapy in a real-world setting, both alone or in combination with intrathecal antisense oligonucleotide nusinersen therapy in two cohorts of patients with spinal muscular atrophy (SMA). The first cohort included eight presymptomatic infants treated solely with onasemnogene abeparvovec, while the second cohort comprised six symptomatic infants receiving onasemnogene abeparvovec and nusinersen co-therapy. All patients received the corticosteroid prednisolone coincident with gene therapy. Circulating alanine aminotransferase (ALT) and aspartate transaminase (AST) levels were measured to determine potential hepatoxicity, the primary focus of this study. Elevated ALT and AST levels were observed in one p
