- The study included 109 participants, with 53 adults (48.6%), and demonstrated stable disease severity scores over four years.
- Arimoclomol was well-tolerated, with safety observations consistent with its established profile.
- Zevra has submitted a Marketing Authorization Application to the European Medicines Agency for arimoclomol.
The big picture
Zevra's long-term data for arimoclomol reinforces its position in the rare disease space, particularly for NPC. The stability of disease severity scores over four years provides a strong case for sustained efficacy, which is critical for maintaining regulatory approvals and market access. As Zevra seeks to expand its geographic footprint, the real-world evidence from this study will be pivotal in supporting its commercial strategy.
