AveXis receives positive CHMP opinion for Zolgensma, the only gene therapy for spinal muscular atrophy (SMA) - Seite 3

Additional supportive data included interim results from the ongoing SPR1NT trial, a Phase 3, open-label, single-arm study of a single, one-time IV infusion of Zolgensma in presymptomatic patients (<6 weeks at age of dosing) genetically defined by bi-allelic deletion of SMN1 with 2 or 3 copies of SMN2. These data demonstrate rapid, age‑appropriate major milestone gain, reinforcing the critical importance of early intervention in SMA patients.⁴

The most commonly observed side effects after treatment were elevated liver enzymes and vomiting. Acute serious liver injury and elevated aminotransferases can occur. Patients with pre-existing liver impairment may be at higher risk. Prior to infusion, physicians should assess liver function of all patients by clinical examination and laboratory testing. And, they should administer systemic corticosteroid to all patients before and after treatment, and then continue to monitor liver function for at least 3 months after infusion.⁴

“We are delighted to know that EMA considers a new treatment effective to fight SMA and that it can benefit a part of our community. We rely on all relevant stakeholders, to work at their best to get it to patients without any delay. SMA Europe will continue working to ensure that all patients living with SMA in Europe have the possibility to access any treatment that can be beneficial for them in a timely and sustainable way,” said Mencía de Lemus, President of SMA Europe.

Zolgensma “Day One” access program

SMA is a significant burden to the healthcare system in Europe with cumulative estimated healthcare costs per child ranging between €2.5 to €4 million within the first 10 years alone.¹
Designed to work within existing pricing and reimbursement frameworks, yet recognizing the novel nature of a one-time gene therapy for a devastating and progressive disease, the “Day One” access program offers ministries of health and reimbursement bodies (in countries without pre-existing early access pathways) a variety of flexible options that can be implemented immediately at time of approval. The program is designed to ensure that the cost of patients treated before national pricing and reimbursement agreements are in place, are aligned with the value-based prices negotiated following clinical and economic assessments. The program is meant to ensure the continued integrity of the local pricing and reimbursement framework. AveXis is already in advanced discussions with multiple countries in Europe to agree on terms of the program. The following options can be customized for each country:
