Phelan-McDermid Therapy Given Rare Disease Status
FDA has granted Neuren Pharmaceuticals a rare pediatric disease designation for its drug candidate NNZ-2591 and its use in treating Phelan-McDermid syndrome. The designation may qualify Neuren for a priority review voucher if its therapy gains approval.
The designation is based on recent data from a Phase 2 trial of NNZ-2591, a treatment for children with Pitt Hopkins syndrome, a neurodevelopmental disorder caused by mutations in the TCF4 gene on chromosome 18. The trial showed that NNZ-2591 led to improvements as assessed by clinicians and caregivers, Neuren says, adding that it is preparing for an end-of-Phase 2 meeting with FDA in the third quarter to further discuss the therapy’s development program.
