Novartis says it has received nine reports of tumors in patients previously treated with Zolgensma since the spinal muscular atrophy gene therapy was first approved in 2019. Seven of the reports were newly disclosed. In two cases, analyses found evidence that the therapy’s viral vector DNA had integrated into patients’ DNA. Novartis said both patients received treatment for their tumors and are being monitored. The other seven reports have not been established as caused by Zolgensma.
