At two years, 60% of patients who were overweight or obese at baseline experienced clinically meaningful improvements in body mass index, and 61% of those with insulin resistance at baseline were no longer insulin resistant Improved outcomes associated with excess androgens, including acne and androstenedione-to-testosterone ratio were also observed CRENESSITY delivered sustained reductions in adrenocorticotropic hormone and 17-hydroxyprogesterone, while enabling lower, more physiologic glucocorticoid dosing SAN DIEGO, May 1, 2026 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the presentation of new two-year data from the Phase 3 CAHtalyst® Pediatric study demonstrating durable androgen control, sustained decreases in glucocorticoid (GC) doses and meaningful improvements in clinical outcomes associated with excess androgens and long-term GC exposure in children and adolescents with classic congenital adrenal hyperplasia treated with CRENESSITY® (crinecerfont). Consistent with these findings, patients with classic congenital adrenal hyperplasia (CAH) continued to experience substantial reductions in adrenocorticotropic hormone (ACTH) and 17-hydroxyprogesterone (17-OHP) while achieving lower, more physiologic GC doses. These data build upon previously reported one-year clinical outcomes results and were presented at the Pediatric Endocrine Society 2026 Annual Meeting in San Francisco. "These two-year findings showed that CRENESSITY achieved durable reductions in both androgen levels and glucocorticoid doses in children and adolescents with classic congenital adrenal hyperplasia, a population particularly vulnerable to the long-term health impact of excess hormone exposure during growth and development," said Sanjay Keswani, M.D., Chief Medical Officer, Neurocrine Biosciences. "Improved hormonal control was associated with meaningful improvements in clinical outcomes, including body mass index and insulin resistance, supporting healthier outcomes as patients transition into adulthood." These findings highlight the broader clinical implications of improved hormonal control and reduced GC exposure in pediatric patients with classic CAH. The analysis included 86 participants aged four to 17 years who completed up to two years of CRENESSITY treatment in the open-label extension of the CAHtalyst Pediatric study. Mean changes from baseline in key hormonal markers, including ACTH and 17-OHP, measured prior to the morning GC dose, were reported through Month 24. ACTH and 17‑OHP Reductions Meaningful and durable reductions in mean ACTH and 17-OHP were observed at 12 months, with further reductions observed at 24 months, despite sustained decreases in GC doses during the same period. Clinically meaningful improvements were observed across outcomes related to hormone control, excess androgens and long-term supraphysiologic GC exposure among relevant participants at baseline. "In pediatric patients with classic congenital adrenal hyperplasia, excess androgens can accelerate bone age and drive early puberty, which can result in reduced final adult height. This, along with chronic supraphysiologic glucocorticoid exposure, can impact cardiometabolic health and quality of life in patients with CAH," said Mimi Kim, M.D., MSc, Associate Professor of Clinical Pediatrics, Keck School of Medicine, University of Southern California, Principal Investigator for CAHtalyst Pediatric. "These findings underscore the potential for CRENESSITY to redefine the treatment paradigm for patients with CAH by providing sustained control of androgens and allowing for significant reductions in glucocorticoid dosing – this could ultimately lead to important improvements in key long-term patient outcomes." Hormone Control and Excess Androgen Outcomes Among patients with acne at baseline (visual analog scale [VAS] score >0; range 0-100; mean baseline score: 25.4 mm; n=58), mean acne severity decreased by 6.5 mm at Month 12 (n=52) and by 11.0 mm at Month 24 (n=43), indicating progressive improvement over time. In female participants with a baseline hirsutism VAS score >0 (mean baseline score: 27.3 mm; n=29), mean hirsutism scores were largely stable over two years, with a mean change of -6.3 mm at Month 12 (n=27) and +2.4 mm at Month 24 (n=21), despite lower GC doses and continued pubertal stage progression. Among male participants Tanner stage 2 or above with an androstenedione-to-testosterone (A4/T) ratio ≥0.5 at baseline (n=32), 31% (9/29) and 36% (9/25) achieved an A4/T ratio <0.5 at Months 12 and 24, respectively. Supraphysiologic GC Exposure Outcomes Among participants with obesity at baseline (body mass index [BMI] ≥85th percentile), 60% achieved clinically meaningful improvements (≥0.2 reduction) in BMI standard deviation score (SDS) at Month 24 with CRENESSITY, including 23% who achieved a BMI <85th percentile. Among participants with insulin resistance at baseline, 61% had a homeostatic model assessment of insulin resistance (HOMA-IR) value that no longer met the criteria for insulin resistance with CRENESSITY at two years of treatment. *Among participants with overweight/obesity (BMI ≥85th percentile) at baseline. †Among participants with insulin resistance at baseline. Treatment with CRENESSITY was generally well tolerated by patients, with more than 80% study retention at two years and no new safety signals observed. Neurocrine recently presented two-year data in adults at the American Association of Clinical Endocrinology 2026 Annual Meeting and plans to share additional two-year data across clinical endpoints and outcomes at upcoming medical meetings. 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. Severe enzyme deficiency leads to an inability of the adrenal glands to produce enough cortisol and, in approximately 75% of cases, aldosterone. Because individuals with CAH are typically 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 adrenal crisis and even death. Exogenous glucocorticoids (GCs) are necessary to correct the endogenous cortisol deficiency, but historically, doses higher than those needed for cortisol replacement (supraphysiologic) have been used to lower the elevated levels of adrenocorticotropic hormone (ACTH) and adrenal androgens. However, GC treatment at supraphysiologic 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 supraphysiologic GCs may have psychological and cognitive impacts, 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, in addition to cardiometabolic and fertility issues in both sexes. The symptoms of high ACTH may include testicular adrenal rest tumors (TARTs). About CRENESSITY ® (crinecerfont) CRENESSITY is a potent and selective oral corticotropin-releasing factor type 1 receptor (CRF1) antagonist that reduces and controls 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. For adults 18 years of age 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. About The CAHtalyst ® Studies The Phase 3 CAHtalyst global registrational studies were designed to evaluate the safety, efficacy and tolerability of CRENESSITY® (crinecerfont) 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 four to 17 years of age. 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 18 to 58 years of age. 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. Important Information Approved Uses CRENESSITY ® (crinecerfont) is a prescription medicine used together with glucocorticoids (steroids) to control androgen (testosterone-like hormone) levels in adults and children 4 years of age and older with classic congenital adrenal hyperplasia (CAH).
