A Selective Nonpeptide Somatostatin Receptor 5 (SST5) Agonist Effectively Decreases Insulin Secretion in a KATPHI Mouse Model and in Human HI Islets

Inactivating mutations of ß-cell KATP channels cause the most common and severe form of congenital hyperinsulinism (HI), a ß-cell disorder that results in dysregulated insulin secretion and persistent hypoglycemia. Children with KATPHI are typically unresponsive to diazoxide, the only FDA-approved drug for HI. Octreotide, an SST2-selective agonist peptide that inhibits insulin secretion, is used as second line therapy, but poor efficacy and SST2...

Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in neonates, infants, and children, and is caused by genetic mutations in pancreatic beta-cells. Current therapies are burdensome, have limited efficacy, and are associated with significant morbidity. CRN04777 is a potent, orally-bioavailable, selective SST5 agonist that suppresses insulin secretion in the terminal steps of the insulin secretion pathway and could be useful for patients with con...

CRN04777 is an orally administered nonpeptide that is a potent and selective agonist of somatostatin 5 (SST5) receptors and is currently under development for the treatment of congenital hyperinsulinism (HI), the most common cause of persistent hypoglycemia in newborns and infants. Congenital HI arises from mutations within the insulin secretion pathway and is characterized by excessive and/or inappropriate insulin secretion by pancreatic islet beta cells. This excess insulin ...
