638-P: A Novel, Long-Acting Dual Agonist for GIPR/GLP-1R, HISHS-2001, Demonstrates Effects on HbA1c and Weight Loss in the db/db Mouse Model of Type 2 Diabetes

Abstract

HISHS-2001 is a novel long-acting, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) dual receptor (R) agonist. In in vitro cAMP assays in human GIP/GLP-1 receptor-expressing cells, HISHS-2001 exerted half-maximal effects at concentrations of 2.3 nM and 4.1 nM on the receptors for GIP (GIPR) and GLP-1 (GLP-1R) respectively. After SC dosing every third day for four weeks, HISHS-2001 at 3, 10 and 21 nmol/kg demonstrated robust effects on HbA1c in db/db mice which were superior to semaglutide and tirzepatide (Table). The effect on body weight was more pronounced with HISHS-2001 than semaglutide and similar to tirzepatide which was associated with a reduction in food intake. Interestingly, HISHS-2001 led to a significant increase in uncoupling protein-1 (UCP-1) levels in intrascapular brown adipose tissue, in inguinal white adipose tissue and serum and liver fibroblast growth factor-21 (FGF-21) levels. A decrease in serum interleukin-6 (IL-6) level was also observed.In conclusion, HISHS-2001 is a potent, long acting GIP/GLP-1R dual agonist, which provides improved control of glucose homeostasis in diabetic mice compared to an existing GLP-1 agonist and a GIP/GLP-1R dual agonist.View largeDownload slideView largeDownload slide DisclosureV.
