Conditions

Primary Sclerosing Cholangitis

Brief summary

Primary objective: To evaluate the efficacy of hymecromone plus standard of care compared with standard of care alone in the treatment of adolescents and adults with primary sclerosing cholangitis (PSC). Secondary objectives: To evaluate the change in Alkaline Phosphatase (ALP) from baseline to 6 months post-treatment following treatment with hymecromone plus standard of care compared with standard of care. To evaluate changes in biomarkers of PSC disease during hymecromone treatment, namely: (a) fibrotic effect (FibroScan); (b) inflammatory biomarkers (serum Hyaluronan (HA)); and, (c) T-cell count.

Interventions

Hymecromone 400 mg 3 times daily by mouth.

Design outcomes

Primary

MeasureTime frame
Change in serum gamma-glutamyltransferase (GGT) levelsBaseline to Month 6

Secondary

MeasureTime frameDescription
Change in serum hyaluronan levelsBaseline to Month 6
Change in T-cell countBaseline to Month 6
Change in fibrotic effect based on FibroScanBaseline to Month 6Fibrotic effect is the amount of liver with fatty change
Change in biliary tree anatomy (e.g. strictures) based on FibroScanBaseline to Month 6
Change in serum Alkaline Phosphatase (ALP) levelsBaseline to Month 6
Change in lymphocyte immunophenotypeBaseline to Month 6Single cell analysis technique will be used to assess the lymphocytes (B- and T-cells) present in serum samples, including FoxP3+ regulatory T-cells, a tolerogenic lymphocyte subset with important roles in immune tolerance.
Plasma drug levels of 4-MUSingle blood draw at baseline, week 2, and months 1, 3, and 6 study visits
Plasma drug levels of 4-MUGSingle blood draw at baseline, week 2, and months 1, 3, and 6 study visits
Plasma drug levels of 4-MUSSingle blood draw at baseline, week 2, and months 1, 3, and 6 study visits
Change in serum inflammatory cytokine profileBaseline to Month 6This outcome measure will assess pro-inflammatory cytokines previously associated with biliary inflammation and other autoimmune diseases including IFNg, IL-6, and TNF.
