Neurocrine Biosciences, Inc. (NASDAQ:NBIX) today announced the U.S. Food and Drug Administration (FDA) has accepted its two New Drug Applications (NDA) with Priority Review designations for crinecerfont in the treatment of children, adolescents and adults with classic congenital adrenal hyperplasia (CAH). If approved, crinecerfont would be the first new treatment option for CAH in 70 years and a first-in-class therapy, with a novel approach for the treatment of this rare and serious endocrine disorder.

The submitted crinecerfont NDAs included: the primary presentation of efficacy and safety of crinecerfont for the treatment of classic CAH as (1) a capsule formulation (NDA# 218808); and (2) as an oral solution formulation (NDA# 218820). The agency set Prescription Drug User Fee (PDUFA) target action dates of December 29 and December 30, 2024, respectively. The FDA stated it is not currently planning to hold an advisory committee meeting to discuss these applications.

Priority Review designation by the FDA accelerates the review timeline by four months – and means the agency recognizes CAH is a serious condition with high unmet medical need and crinecerfont is a treatment that provides significant benefit over current therapy. Should crinecerfont receive FDA approval, it will enable Neurocrine Biosciences to activate its Rare Pediatric Disease Designation Priority Review Voucher – a designation granted in September 2020.
