Novartis AG — Zolgensma EMA EPAR public assessment report (EMEA/H/C/004750, 2020)

Report summary

The EMA granted Zolgensma (onasemnogene abeparvovec) a Conditional Marketing Authorisation in March 2020 for Spinal Muscular Atrophy (SMA) Type 1, recognizing its potential to address a significant unmet medical need. The regulatory assessment, initially accelerated, reverted to standard due to data deficiencies. Quality aspects, including manufacturing processes (Process A and B), characterization, and stability, were thoroughly reviewed. Non-clinical studies in various animal models highlighted the importance of early administration for efficacy, but also revealed cardiovascular and liver toxicity, particularly with Process B material, and dorsal root ganglia toxicity in non-human primates. Clinical trials (CL-101, CL-303, etc.) demonstrated significant improvements in survival, motor milestones, and CHOP-INTEND scores compared to natural history, especially in younger patients. Common adverse events included elevated liver enzymes and pyrexia, with rare but serious cardiac events and acute liver failure. The limited safety database necessitates ongoing monitoring for long-term safety and efficacy, particularly regarding potential cardiac and DRG toxicities.
