Primary Outcome(s)

Timepoint(s) of evaluation of this end point: For each patient, the change from Baseline in PKAN-ADL scores at Weeks 3, 6, 12, 18, and 24 of the double-blind period will be used for analysis.

Main Objective: The efficacy objective of this study is to evaluate the efficacy of fosmetpantotenate over 24 weeks in patients with PKAN.
The safety objective of the study is to assess the safety and tolerability of fosmetpantotenate in patients with PKAN.

Secondary Objective: To determine the PK following multiple doses of fosmetpantotenate in patients with PKAN.
To explore potential biomarkers of disease, along with their potential response to treatment in patients with PKAN.

Primary end point(s): Primary Efficacy Endpoint
- Change in the score from the PKAN-ADL, from Baseline to the end of the 24-week double-blind period

Safety Endpoint
- Safety and tolerability of fosmetpantotenate

Secondary Outcome(s)

Secondary end point(s): Secondary Efficacy Endpoint
- Change in the score from Part III of the Unified Parkinson’s Disease Rating Scale (UPDRS) from Baseline to the end of the 24-week double-blind period

Timepoint(s) of evaluation of this end point: Continuous measures recorded at each study visit from Baseline to the end of the 24-week double-blind period.
