NCT05295680

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.
