Neurocrine Biosciences, Inc. announced that it will present key information from its neuroendocrinology pipeline, including baseline characteristics data from its CAHtalyst? Program of crinecerfont in congenital adrenal hyperplasia (CAH), as well as data from its modified-release hydrocortisone studies in primary adrenal insufficiency and CAH, at the European Congress of Endocrinology 2024 meeting in Sweden, May 11?14. Crinecerfont is an investigational, oral, selective corticotropin-releasing factor type 1 receptor (CRF1) antagonist being developed to reduce and control excess adrenal androgens through a glucocorticoid-independent mechanism for the treatment of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Antagonism of CRF1 receptors in the pituitary has been shown to decrease adrenocorticotropic hormone levels, which in turn decreases the production of adrenal androgens and potentially the symptoms associated with CAH. data demonstrate that lowering adrenal androgen levels enables lower, more physiologic dosing of glucocorticoids and thus could potentially reduce the complications associated with exposure to greater than normal glucocorticoid doses in patients with CAH.

The CAHtalyst? Pediatric and Adult Phase 3 global registrational studies are designed to evaluate the safety, efficacy, and tolerability of crinecerfont in children and adolescents, and adults respectively, with congenital adrenal hyperplasia due to 21-hydroxylase deficiency. The primary portions of the CAHtalyst Phase 3 studies have completed and enrollment is closed, while the open-label treatment portions of both studies are ongoing.
