Neurocrine Biosciences has announced that the US Food and Drug Administration (FDA) has accepted its two New Drug Applications (NDA) for crinecerfont, granting them Priority Review designations. The applications cover the treatment of children, adolescents, and adults with classic congenital adrenal hyperplasia (CAH). If approved, crinecerfont would represent the first new treatment for CAH in 70 years and the first-in-class therapy offering a novel mechanism of action to address this rare and serious endocrine disorder.

LAS VEGAS , Sept. 30, 2024 /PRNewswire/ -- CAH refers to a rare set of inherited autosomal recessive disorders that impair hormone production in the adrenal glands, which sit on top of the kidneys. Normally, these glands produce three types of hormones: corticosteroids, mineralocorticoids, and androgens.

CAH is mostly caused by mutations in the 21-hydroxylase gene, which accounts for more than 90% of cases. In rare instances, mutations in the 11-hydroxylase gene can also lead to CAH. In the 7MM, the US accounted for the highest prevalent cases of congenital adrenal hyperplasia in 2023, with around 50% of the total prevalent cases across the 7MM; these numbers are expected to increase during the forecast period (2024–2034).

DelveInsight's analysis reveals that a higher prevalence of diagnosed congenital adrenal hyperplasia is observed in the 18-year-old and above age group across the 7MM. Among mutation-based congenital adrenal hyperplasia cases, 21 OHD (CYP.
