AveXis receives positive CHMP opinion for Zolgensma, the only gene therapy for spinal muscular atrophy (SMA) - Seite 2

The European Commission (EC) reviews the CHMP recommendation and usually delivers its final decision in approximately two months. The decision will be applicable to all 27 European Union member states, as well as Iceland, Norway, Liechtenstein and the United Kingdom.

“Today’s positive CHMP opinion for Zolgensma marks a critical step closer to EC approval and to bringing the only gene therapy for SMA to Europe, helping to address the devastating impact the disease has on patients and their families,” said Dave Lennon, president of AveXis. “Zolgensma provides a transformational new way to treat this rare but debilitating disease – delivering a potentially life-saving medicine with a one-time administered treatment. Given the urgency to treat SMA and the novel nature of gene therapy, we need to be equally innovative in advancing access, so we are offering governments and reimbursement bodies a ‘Day One’ access program to enable rapid access to Zolgensma upon approval.”

“In the most severe forms of the disease, children who are not treated are unable to lift their heads, sit, stand, or even swallow, and typically do not survive beyond two years of age unless permanently ventilated,” said Dr. Francesco Muntoni, Professor and Pediatric Neurologist at Great Ormond Street Hospital for Children, London. “The results we have seen for Zolgensma to date from the STR1VE clinical trial show an impressive survival rate at the conclusion of the study, with the majority of patients being able to sit without support. And through follow-up on the START trial, an average of 4.5 years later, we can see the long-term potential this significant gene therapy may have for children with this rare disease.”

The CHMP positive opinion is based on the completed Phase 3 STR1VE-US and Phase 1 START trials that evaluated the efficacy and safety of a one-time IV infusion of Zolgensma in symptomatic SMA Type 1 patients <6 months of age at dosing, who had one or two copies of the SMN2 backup gene, or two copies of the SMN2 backup gene, respectively. STR1VE-EU, a comparable Phase 3 study is ongoing. Zolgensma demonstrated prolonged event-free survival; rapid motor function improvement, often within one month of dosing; and, sustained milestone achievement, including the ability to sit without support, a milestone never achieved in untreated Type 1 patients.⁴
