Novel bile acid therapy to treat liver diseases
About Qing Bile
Qing Bile Therapeutics is a preclinical stage, private Canadian biotechnology company founded in 2015 based on research from Dr. Victor Ling’s laboratory at the University of British Columbia and BC Cancer Agency.
Qing Bile has identified tetrahydroxylated bile acids (THBAs) to treat cholestatic and metabolic diseases with high unmet need.
Qing (“Ching”) is derived from the Chinese word for clear/pure.
Science of THBA
THBAs are novel bile acids that are not normally present in the mouse or human bile. Qing Bile’s scientists discovered THBA in Bsep -/- mice, a model of human progressive familial intrahepatic cholestasis type II (PFIC2).
While livers of Bsep -/- mice are enlarged compared to control mice, they showed a non-progressive, mild cholestatic phenotype with normal levels of liver indicators and normal hepatocyte morphology.
Higher levels of THBA (generated by polyhydroxylation of bile acid) was associated with detoxification of bile acid pool, reduced liver injury, and promoted the survival of these animals.
Qing Bile has identified superior THBA isomers for IND-enabling studies.
Advantages of THBA
THBAs are less hydrophobic - less toxic than UDCA (current standard of care) and norUDCA (in clinical development for PSC) in human hepatocyte toxicity assay, and more effective in a gold standard cholestasis model.
THBA acts as a hydrophilic solute to :
Detoxify bile acid pool
Stimulate bile flow
Reduce cholangitis, inflammation, and fibrosis
Lower risk of liver failure and hepatocellular carcinoma
THBA may be complementary to other therapies that aim to decrease liver exposure to bile acids.
Our lead preclinical candidates (QBT-002 and QBT-006) are ready for IND-enabling studies and our focus is on rare diseases - progressive familial intrahepatic cholestasis (PFIC) and primary sclerosing cholangitis (PSC), where there are currently no approved medical therapies. THBA has also been tested in a preclinical model of nonalcoholic steatohepatitis (NASH) with initial positive results.
