A treatment for classic congenital adrenal hyperplasia (CAH) has been approved by the US Food and Drug Administration – the first new drug in decades for a genetic disorder involving the adrenal glands. The drug, Crenessity (crinecerfont), is a small molecule to be used as an adjunct to glucocorticoids. In two randomised, placebo-controlled trials in adults and children Crenessity was able to reduce an overproduction of androgen in adults and children relative to the production of cortisol, an essential hormone. This was achieved without the need for high levels of glucocorticoids.
