Clinical Trials

Congenital Adrenal Hyperplasia

Neurocrine Biosciences completed a Phase II study evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of crinecerfont in adult patients with classic congenital adrenal hyperplasia (CAH). The final results from this open-label, multiple-dose, dose-escalation study were reported in June 2020.

Neurocrine Biosciences is currently enrolling patients in global registrational studies of crinecerfont in adult (18 years and older) and pediatric (2 years to 17 years) patients with classic CAH.
