Brief summary

The primary endpoints as measured in study patients, regardless of region and country, but submitted as primary to the EU and RoW are: • Interim Analysis: Mean change in the 5D-NPC-SS composite score (Ambulation, Fine Motor, Speech, Swallow, and Cognition) from Baseline (Week 0) to 48 weeks, The primary endpoints as measured in study patients, regardless of region and country, but submitted as primary to the EU and RoW are:• Final Analysis: Mean change in the 5D-NPC-SS composite score (Ambulation, Fine Motor, Speech, Swallow, and Cognition) from Baseline (Week 0) to 96 weeks, The primary endpoints as measured in all study patients, regardless of country, but submitted as primary to US are: • Interim Analysis: Mean change in the 4D-NPC-SS (Ambulation, Fine Motor, Speech, and Swallow) composite score from Baseline (Week 0) to 48 weeks, The primary endpoints as measured in all study patients, regardless of country, but submitted as primary to US are:• Final Analysis: Mean change in the 4D-NPC-SS (Ambulation, Fine Motor, Speech, and Swallow) composite score from Baseline (Week 0) to 96 weeks

Detailed description

Mean change from Baseline in the SCAFI at 48 and 96 weeks, Mean change from Baseline in the Vineland-2 composite raw score, including the optional Motor Skills domain, at 48 and 96 weeks, Mean change from Baseline in the patient’s ability to swallow as assessed by the PAS, at 48 and 96 weeks (at select sites)
