SAN DIEGO, Dec. 13, 2024 /PRNewswire/ --

Neurocrine Biosciences, Inc.

(Nasdaq: NBIX ) today announced the U.S. Food and Drug Administration has approved CRENESSITYTM (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.

CAHtalystTM Clinical Program Overview:

The FDA approval is supported by the largest-ever clinical trial program of classic CAH, the CAHtalyst Pediatric and Adult Phase 3 global registrational studies. CAHtalyst

Phase 3 data results in

pediatric

and

adult

patients with classic CAH were published in

The New England Journal of Medicine.

"The clinical results across both CAHtalyst studies support the efficacy and safety profile of CRENESSITY and its ability to reduce the overproduction of adrenal androgens, allowing for a meaningful reduction in glucocorticoid dosage, while maintaining or enhancing control of these androgens," said Richard Auchus, M.D., Ph.D., Professor, University of Michigan Health, Principal Investigator. "Chronic treatment with supraphysiologic glucocorticoids can cause a number of short- and long-term health consequences, such as obesity, hypertension and osteoporosis, so the ability for patients with CAH to lower their glucocorticoid dose to a more physiologic level can have profound benefits."

In both CAHtalyst studies, CRENESSITY enabled lower steroid doses and decreased androgen levels.

Phase 3 CAHtalyst Pediatric Study:



The CAHtalyst Pediatric study met its primary endpoint, with CRENESSITY significantly decreasing androstenedione levels from baseline to Week 4 versus patients taking placebo who experienced a substantial increase in androstenedione levels.

Children taking CRENESSITY were also able to significantly reduce their GC doses at Week 28 while maintaining or improving androgen levels, a key secondary endpoint.

Children taking CRENESSITY saw approximately four times greater reduction in androstenedione compared with those taking placebo.

Approximately four times greater steroid dose reduction in children taking CRENESSITY was seen compared with those taking placebo.

Children taking CRENESSITY saw approximately 12 times greater reduction in 17-hydroxyprogesterone (17-OHP) compared with those taking placebo. Headache, abdominal pain, fatigue, nasal congestion and nosebleed were the most common adverse drug reactions (ADRs) among the pediatric population treated with CRENESSITY. Most side effects were temporary and mild to moderate in severity.

Phase 3 CAHtalyst Adult Study:



The CAHtalyst Adult study met its primary endpoint with CRENESSITY enabling significant GC dose reductions at Week 24 (while maintaining or improving baseline androstenedione levels) and key secondary endpoint of decreasing androstenedione levels at Week 4.

A significantly higher number of patients taking CRENESSITY (63%) achieved a GC dose in the physiologic range while androstenedione was maintained or improved compared with patients taking placebo (18%).

Approximately two times greater steroid dose reduction was seen in people taking CRENESSITY compared with those taking placebo.

People taking CRENESSITY saw an eight times greater reduction in androstenedione compared with those taking placebo.

People taking CRENESSITY saw a 37 times greater reduction in 17-OHP compared with those taking placebo. Fatigue, headache, dizziness, joint pain, back pain, decreased appetite and muscle pain were the most common ADRs in the CRENESSITY treatment group. Most side effects were temporary and mild to moderate in severity.

CRENESSITY was well tolerated with few treatment-related adverse events in both CAHtalyst studies. Pediatric and adult patients taking CRENESSITY had no treatment-related serious adverse events.



Adrenal insufficiency and crisis are risks of living with CAH that CRENESSITY does not address and can occur when a patient's GC dose is too low. In the CAHtalyst Pediatric study, there were no cases of adrenal crisis among patients taking CRENESSITY or placebo. In the CAHtalyst Adult study, two patients (1.6%) taking CRENESSITY experienced adrenal crisis. No patients on placebo experienced adrenal crisis. However, one patient (1.7%) on placebo experienced adrenal insufficiency. Patients should work with their healthcare provider to manage GC dosing while taking CRENESSITY.

About Congenital Adrenal Hyperplasia

Congenital adrenal hyperplasia (CAH) is a rare genetic condition that results in an enzyme deficiency that alters the production of adrenal steroid hormones, such as cortisol, aldosterone and adrenal androgens, which are essential for life. Approximately 95% of CAH cases are caused by variants of the CYP21A2 gene that leads to deficiency of the enzyme 21-hydroxylase (21-OH). Severe deficiency of this enzyme leads to an inability of the adrenal glands to produce enough cortisol and, in approximately 75% of cases, aldosterone. Because individuals with CAH are still able to produce androgens, the unused precursors that would normally be used to make cortisol instead result in the production of excess amounts of androgens. If left untreated, CAH can result in salt wasting, dehydration and even death.

Historically, exogenous glucocorticoids (GCs) have been used not only to correct the endogenous cortisol deficiency, but doses used are higher than cortisol replacement needed (supraphysiologic) to lower the levels of adrenocorticotropic hormone (ACTH) and adrenal androgens. However, GC treatment at high doses has been associated with serious and significant complications of steroid excess, including metabolic issues such as weight gain and diabetes, cardiovascular disease and osteoporosis. Additionally, long-term treatment with high-dose GCs may have psychological and cognitive impact, such as changes in mood and memory. Adrenal androgen excess has been associated with abnormal bone growth and development in pediatric patients, female health problems such as excess facial hair growth and menstrual irregularities, testicular rest tumors in males and fertility issues in both sexes.

About The CAHtalystTM

Studies

The Phase 3 CAHtalystTM

global registrational studies were designed to evaluate the safety, efficacy and tolerability of CRENESSITY in children and adults with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The CAHtalyst studies were the largest-ever clinical trial program in classic CAH, including 285 pediatric and adult patients.

The CAHtalyst Pediatric study included 103 pediatric patients aged four to 17 years. The study tested two questions. The first question evaluated whether four weeks of CRENESSITY treatment could improve androgen control. The second question evaluated whether an additional 24 weeks of CRENESSITY treatment enabled customized glucocorticoid (GC) down-titration while androstenedione levels were maintained or improved. The CAHtalyst Adult study included 182 adult patients aged 18 to 58 years. Similarly, the first question of the study evaluated whether four weeks of CRENESSITY treatment could improve androgen control, and the second question evaluated whether an additional 20 weeks of CRENESSITY treatment enabled GC reduction to physiologic range while androstenedione levels were maintained or improved.

Data from the CAHtalyst Phase 3 studies supported approval of CRENESSITY by the U.S. Food and Drug Administration

in

December 2024. The

open-label extension treatment portions of both studies are ongoing.

About CRENESSITYTM (crinecerfont)

CRENESSITYTM is a potent and selective, oral corticotropin-releasing factor type 1 receptor (CRF1) antagonist developed to reduce and control excess adrenocorticotropic hormone (ACTH) and adrenal androgens through a non-glucocorticoid (GC) mechanism for the treatment of classic congenital adrenal hyperplasia (CAH). Antagonism of CRF1

receptors in the pituitary has been shown to decrease ACTH levels, which in turn decreases the production of adrenal androgens and potentially the symptoms associated with CAH. The robust clinical study data demonstrate that lowering adrenal androgen levels with CRENESSITY enables lower, more physiologic dosing of GCs to replace missing cortisol.

CRENESSITY comes in capsules and an oral solution. The capsule formulation is available in 50 mg and 100 mg doses. The oral solution is available as a 50 mg/mL strength formulation. For adults 18 years and older, the recommended dosage is 100 mg twice daily taken orally with a meal. For pediatric patients four to 17 years of age weighing less than 55 kg (121 lbs), the recommended dosage is based on body weight and is administered twice daily, taken orally with a meal. For pediatric patients weighing more than 55 kg (121 lbs), the recommended dosage is 100 mg twice daily taken orally with a meal. Healthcare providers can work with patients to determine the appropriate formulation for use depending on patient needs. Patients receiving CRENESSITY should continue GC therapy for cortisol replacement.
