Dec 13 (Reuters) - The U.S. Food and Drug Administration has approved Neurocrine
Biosciences' NBIX.O drug to treat a type of genetic disorder, the health regulator's website
showed on Friday.
The drug, branded as Crenessity, is to be used together with glucocorticoid, a type of
steroid, to control androgen levels in adults and pediatric patients aged 4 years and older with
classic congenital adrenal hyperplasia (CAH).
The drug is expected to be commercially available in about one week, a company spokesperson
said.
CAH is a rare genetic disorder affecting the adrenal glands, which produce hormones such as
cortisol and androgens.
Patients with the disease do not produce enough cortisol — an essential hormone that
regulates stress levels — and produce too many androgens, a testosterone-like hormone.
Crenessity works by reducing excessive production of androgens, resulting in less amount of
glucocorticoid treatment needed.
Patients usually require high doses of glucocorticoids, beyond what is required to replace
cortisol, because they also help lower excess androgen levels.
