CoA-Z in Pantothenate Kinase-associated Neurodegeneration (PKAN)

Not Applicable

• Conditions: Pantothenate Kinase-Associated Neurodegeneration

• Registration Number: NCT04182763
• Lead Sponsor: Oregon Health and Science University

Brief Summary

The purpose of this study is to learn more about how people with the condition pantothenate kinase-associated neurodegeneration (PKAN) respond to a specialized study product. We are hoping to find out if the study product is safe, what effects-good and bad-the study product causes, and whether the study product changes certain measures of disease in PKAN.

Primary Outcome Measures

Name	Time	Method
Percentage of participants experiencing clinically significant laboratory abnormalities on Comprehensive Metabolic Profile.	24 months	Safety will be assessed by measuring the percentage of participants experiencing clinically significant laboratory abnormalities on Comprehensive Metabolic Profile by collection month. Clinical significance will be determined by Medical Safety Monitor and Clinical Investigators.
Percentage of participants experiencing clinically significant laboratory abnormalities on Complete Blood Count.	24 months	Safety will be assessed by measuring the percentage of participants experiencing clinically significant laboratory abnormalities on Complete Blood Count by collection month. Clinical significance will be determined by Medical Safety Monitor and Clinical Investigators.
Number of participants experiencing clinically significant laboratory abnormalities on Comprehensive Metabolic Profile.	24 months	Safety will be assessed by measuring the number of participants experiencing clinically significant laboratory abnormalities on Comprehensive Metabolic Profile by collection month. Clinical significance will be determined by Medical Safety Monitor and Clinical Investigators.
Number of participants experiencing adverse events assessed by CTCAE v4.0	24 months	Safety will be measured by measuring the number of participants experiencing adverse events by study period and treatment arm
Percentage of participants experiencing adverse events assessed by CTCAE v4.0	24 months	Safety will be measured by measuring the percentage of participants experiencing adverse events by study period and treatment arm
Number of participants experiencing clinically significant laboratory abnormalities on Complete Blood Count.	24 months	Safety will be assessed by measuring the number of participants experiencing clinically significant laboratory abnormalities on Complete Blood Count by collection month. Clinical significance will be determined by Medical Safety Monitor and Clinical Investigators.
Number of participants retained in each arm.	24 months	Tolerability will be assessed by measuring the number of participants retained in each arm at each follow up time point.
Mean percent of study product consumed.	24 months	Tolerability will be assessed by adherence to the study product regimen arm at each follow-up time point.

Secondary Outcome Measures

Name	Time	Method
Ratio of CoASY mRNA expression level to that of 18s, an internal control	24 months	The pharmacodynamic profile of a putative disease biomarker will be assessed by measuring the mean level of CoASY gene expression by treatment arm across study timepoints.
