Galecto, Inc. develops small molecules for the treatment of cancer and severe liver diseases. The company is built on nearly 15 years of research centering on the role of galectin-3 and the use of modulators of these proteins to treat cancer and severe liver diseases. These assets, combined with BRM-1420, a novel dual ENL-YEATS / FLT3 inhibitor, provide Galecto with a unique therapeutic platform.
Liver Disease
Galecto is developing GB1211 as a potential treatment for patients with severe liver diseases. GB1211 is an orally bioavailable first-in-class, potent and high-affinity small molecule galectin-3 inhibitor, which has demonstrated antifibrotic activity in preclinical therapeutic liver disease models [1].
The global burden of these diseases, including alcohol-associated cirrhosis, non-alcoholic steatohepatitis (NASH) cirrhosis, and liver cancers, is immense [2, 3, 4], and there are no approved treatments. The overall survival for patients with decompensated cirrhosis is poor, with a median survival of approximately 2 years [5].
The only intervention/treatment available is liver transplantation. We believe that our expertise in galectin biology can bring substantial improvements to the treatment landscape of these liver diseases.
Galectin-3 is elevated in alcoholic and non-alcoholic cirrhosis as well as in alcoholic hepatitis. Moreover, galectin-3 have been demonstrated to be a prognostic biomarker of hepatocellular carcinoma (a complication of cirrhosis). Additionally, galectin-3 is essential for TFG-β-mediated myofibroblast activation and matrix production in liver fibrosis and linked to hepatocyte senescence and stellate cell activation. Evidence has shown that galectin-3 inhibition reduces liver cell damage in a number of preclinical models [6–9].
We believe galectin-3 inhibition using GB1211 could be a meaningful intervention in severe liver disease.
