Brief summary

CyNCh is a multi-center, placebo-controlled clinical trial of children ages 8 to 17 years with biopsy-confirmed moderate to severe nonalcoholic fatty liver disease (NAFLD). The primary objective is to evaluate whether 52 weeks of treatment with cysteamine bitartrate delayed-release capsules will result in improvement in liver disease severity.

Primary

MeasureTime frameDescription
Improvement in Nonalcoholic Fatty Liver Disease (NAFLD)52 weeksCentrally scored and masked assessment of histologic improvement in Nonalcholic Fatty Liver Disease (NAFLD) between the baseline liver biopsy and follow-up biopsy after 52 weeks of treatment, where improvement is defined as: (1) decrease in the NAFLD Activity Score (NAS) of 2 or more and (2) no worsening of fibrosis.

Secondary

MeasureTime frameDescription
Change in Nonalcoholic Fatty Liver Disease (NAFLD) Activity Score (NAS)52 weeksChange from baseline in the NAFLD Activity Score (NAS), which is a composite score equal to the sum of the steatosis grade (0-3), lobular inflammation grade (0-3), and hepatocellular ballooning grade (0-2), from centralized pathologist scoring of liver biopsies. The overall scale of the NAS is 0-8, with higher scores indicating more severe disease. The outcome measure, change from baseline in NAFLD Activity Score (NAS), has a possible range from -8 to +8, with negative values indicating a better outcome (improvement) and positive values indicating a worse outcome. Components of the NAS are scored as follows: Steatosis grade 0=\<5% steatosis, 1=5-33% steatosis, 2=34-66% steatosis, 3=\>66% steatosis. Lobular inflammation grade=amount of lobular inflammation (combines mononuclear, fat granulomas, and polymorphonuclear (pmn) foci): 0=0, 1=\<2 under 20x magnification, 2=2-4 under 20x magnification, 3=\>4 under 20x magnification. Hepatocellular ballooning 0=none, 1=mild, 2=more than mild.

Change in fibrosis stage has a possible range of -4 to +4, with negative values indicating a better outcome (improvement) and positive values indicating a worse outcome (no improvement).
Change in Pediatric Quality of Life Inventory (PedsQL) Score52 weeksPediatric Quality of Life Inventory (PedsQL) version 4.0 is completed by both the child and parent/caregiver, and is composed of 23 items comprising 4 dimensions: Physical Functioning, Emotional Functioning, Social Functioning, and School Functioning.

Population: Analysis based on intention to treat; patients with missing 52-week biopsy were imputed as lack of improvement.

Portal Inflammation: Change in Score

Change from baseline in portal inflammation score. The amount of portal inflammation is based on central pathologist grading of liver biopsies: 0=none; 1=mild, 2=more than mild. Change in portal inflammation score has a possible range of -2 to +2, with negative values indicating a better outcome (improvement) and positive values indicating a worse outcome (no improvement).

Time frame: 52 weeks

Population: The smaller number of participants analyzed is due to missing 52-week biopsies (complete case analysis).

Reduction in MRI-determined Hepatic Fat Fraction

Change from baseline in MRI Proton Density Fat Fraction (PDFF) (%).

Time frame: 52 weeks

Population: The smaller number of observations is because MRI was an optional procedure. This is the number with MRI exams at both baseline and 52 weeks.

Steatosis: Change in Score

Change from baseline in steatosis score. Steatosis score is based on central pathologist grading of liver biopsies: 0=\<5% steatosis; 1=5-33% steatosis, 2=34-66% steatosis, 3=\>66% steatosis. Change in steatosis score has a possible range of -3 to +3, with negative values indicating a better outcome (improvement) and positive values indicating a worse outcome (no improvement).
