It has been previously demonstrated that the two coding variants in the APOL1 gene (G1 and G2) are associated with a greater risk of progressive, proteinuric kidney disease; however, there currently are no therapies to address the causal genetic drivers of this disease. Researchers from Maze Therapeutics Inc. presented the discovery and preclinical characterization of a novel small-molecule inhibitor of APOL1, MZ-302, and they evaluated its efficacy in a new transgenic model of APOL1-mediated kidney disease (AKD).
