Neurocrine Biosciences to Present New Data Analyses for Crinecerfont in Adults with Classic Congenital Adrenal Hyperplasia at ENDO 2021
"As we continue to evaluate crinecerfont, we find the additional Phase II analyses that we are presenting at ENDO 2021 very encouraging," said
Of the two additional abstracts, one presents analyses from the International CAH (I-CAH) Registry, a research database that includes patients from 29 countries with longitudinal data dating back to 1989, evaluating the impact of CAH on bone age advancement and growth patterns in pediatric patients. In the other abstract, the company will present analyses from a real-world evidence repository of medical and prescription claims and electronic health records demonstrating the impact of possible glucocorticoid-related and disease-related co-morbidities in over 1,100 adult and pediatric patients with assumed classic CAH.
"These real-world data demonstrate the significant clinical impact that both CAH and its long-term treatment with high doses of glucocorticoids have on patients," said Eiry W. Roberts, M.D., Chief Medical Officer at
Presentations at ENDO 2021 include:
- Changes in Adrenal and Gonadal Androgens After 14-Day Treatment with CRF1 Receptor Antagonist, Crinecerfont (NBI-74788), in Men with Classic 21-Hydroxylase Deficiency (Poster #8486)
- Growth-Related Characteristics of Patients <18 Years of Age with Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency (21-OHD): Real-World Evidence from the I-CAH Registry (Poster #6719)
- Real-World Evidence of Clinical Outcomes in Patients with Assumed Classic Congenital Adrenal Hyperplasia in
the United States(Poster #6968)
All posters will be on display in the virtual poster hall throughout ENDO 2021 starting at
Crinecerfont Phase II Study Design
The Phase II open-label, multiple-dose, dose-finding study assessed the safety, tolerability, pharmacokinetics and pharmacodynamics of crinecerfont in 18 adults with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD). The study's sequential-cohort design evaluated four crinecerfont oral dosing regimens: 50 mg at bedtime (Cohort 1; n=8); 100 mg at bedtime (Cohort 2; n=7); 100 mg once-daily with an evening meal (Cohort 3; n=8); and 100 mg twice-daily with meals (Cohort 4; n=8). Participants in Cohorts 1 and 2 could enroll in Cohorts 3 and/or 4. Each regimen was administered for 14 consecutive days. ACTH, 17-OHP, androstenedione (A4) and testosterone, key disease hormone markers in CAH patients, were measured over a 24-hour period at baseline and after 14 consecutive days of dosing.
About Classic Congenital Adrenal Hyperplasia (CAH)
Classic CAH is a genetic disorder in which an enzyme deficiency alters the production of adrenal hormones. Because of this deficiency, the adrenal glands fail to produce enough cortisol and, in approximately 75% of cases, aldosterone, resulting in a potentially life-threatening condition. The lack of cortisol stimulates the release of high levels of adrenocorticotropic hormone (ACTH) from the pituitary gland, leading to excessive production of adrenal androgens. Elevated androgens can lead to virilization, menstrual irregularities, hirsutism and acne in females, and accelerated growth and precocious puberty in childhood (resulting in short stature and fertility problems) in both males and females.
Corticosteroids, the current standard of care for more than 60 years, are prescribed to treat cortisol deficiency and reduce the high ACTH levels in order to attempt to control androgen excess. However, the dose and duration of glucocorticoids required to suppress ACTH and control androgen levels are often well above what is needed for replacement dosing to treat cortisol deficiency. Long-term, chronic exposure to greater than physiologic dosing of glucocorticoids can cause metabolic issues, bone loss, growth impairment and infection risk typical of iatrogenic Cushing's syndrome. Classic CAH is a disease that affects approximately 30,000 people in the

Crinecerfont is an investigational, oral, non-steroidal corticotropin-releasing factor type 1 (CRF1) receptor antagonist under evaluation for the treatment of classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD). The blockade of CRF receptors in the pituitary has been shown to decrease the release of adrenocorticotropic hormone (ACTH), which in turn decreases the production of adrenal androgens, and potentially the symptoms associated with classic CAH. Adding crinecerfont treatment to glucocorticoid therapy has the potential to reduce the adverse consequences of androgen excess and of long-term exposure to greater than replacement doses of glucocorticoids, enabling patients to better manage the symptoms of classic CAH.
