Neurocrine Biosciences has announced the US Food and Drug Administration has approved CRENESSITY (crinecerfont) capsules and oral solution as an adjunctive treatment to glucocorticoid replacement to control androgens in adult and pediatric patients four years of age and older with classic congenital adrenal hyperplasia (CAH), a rare, serious and lifelong genetic condition involving the adrenal glands.

CRENESSITY, a potent and selective oral corticotropin-releasing factor type 1 receptor (CRF1) antagonist, is the first and only classic CAH treatment that directly reduces excess adrenocorticotropic hormone (ACTH) and downstream adrenal androgen production, allowing for glucocorticoid dose reduction. It is a breakthrough in the treatment landscape for classic CAH.

"For the last three decades, Neurocrine Biosciences, together with our late founder, Wylie W. Vale, has conducted groundbreaking research uncovering the critical role of corticotropin-releasing factor and its receptor, CRF1, in the pathophysiology of congenital adrenal hyperplasia," said Kyle W. Gano, PhD, Chief Executive Officer, Neurocrine Biosciences.

"The approval of CRENESSITY is a significant milestone for the CAH community, and we are grateful to the individuals who participated in our clinical trials, including their families and caregivers, and to the clinical investigators who helped advance a new therapy and class of medicines," added Gano.

"Patients and families struggle to achieve balance between managing the symptoms of CAH and the side effects or complications of treatment with high-dose steroids, which may impact quality of life," said Dina Matos, Executive Director, CARES Foundation.

"We are grateful to Neurocrine Biosciences for engaging with our community throughout the drug development process to understand our needs and ultimately providing this new medication that can help reduce excess adrenal androgens and the need for high-dose steroid treatment for individuals living with CAH," Matos added.

CRENESSITY is expected to be commercially available in approximately one week. The medication will be provided through PANTHERx Rare, a specialty pharmacy, to centralize and simplify CRENESSITY prescription fulfillment.

Neurocrine Biosciences is committed to supporting patients in obtaining treatment with CRENESSITY by offering Neurocrine Access Support, a free, comprehensive assistance program created for patients, caregivers and healthcare providers. It offers a range of options to make sure patients have everything they need to begin and continue taking CRENESSITY.
