The European Medicines Agency (EMA) says it plans to issue advice for physicians using Novartis AG’s Zolgensma, calling on them to monitor patients for any liver injury after treatment.
The statement follows two deaths due to liver failure after treatment with the gene therapy against spinal muscular atrophy, reported by Novartis in August.
From new technologies to the paradigm shifts extending the reach of medicines, we’re charting a new frontier of medicine. As our industry continues to evolve, it’s an exciting time to consider which innovations will shape the future of health. These are the trends I’m watching: pic.twitter.com/Z6v4NAXdnl

Spinal muscular atrophy is a group of rare genetic disorders which affect the nerve cells and cause muscle wasting and weakness.
The advice for healthcare professionals have yet to be approved by further expert panels at EMA, which typically takes a few weeks. Novartis says it had notified health authorities of the deaths and sent letters to update healthcare providers on liver safety in markets including the United States in August.
In Europe, however, such letters had been the subject of discussions with EMA, but Novartis would soon be cleared to send them in EU member states, it adds.
The EMA says that if patients do not respond adequately to treatment with corticosteroids, treating physicians should consult specialists and consider adjusting the corticosteroid regimen. Infusion drug Zolgensma competes with Roche’s oral drug Evrysdi and Biogen’s spinal injection Spinraza.
It won conditional EU approval during early 2020 and it costs more than $2 million per patient.
