- Clinical Trial Results: Neurocrine Biosciences announced new 48-week post-hoc data for Ingrezza from the KINECT 4 trial, revealing that 41% of patients failed to meet the symptomatic remission threshold from previous data, indicating the drug's potential in treating refractory patients.
- Significant Improvements: Among patients who did not achieve symptomatic remission, 86% (36/42) experienced more than a 30% reduction in the Abnormal Involuntary Movement Scale (AIMS) score, while 67% (28/42) achieved over a 50% reduction, demonstrating Ingrezza's efficacy in alleviating movement disorders.
- Drug Mechanism: Ingrezza (Valbenazine) selectively inhibits vesicular monoamine transporter 2 (VMAT2), reducing dopamine release to lower uncontrollable movements, highlighting its unique mechanism of action in treating TD.
- Market Outlook: With approximately 800,000 adults affected by TD in the U.S., Neurocrine's Ingrezza holds significant growth potential in the market, especially as the importance of evaluating hepatic risk factors in personalized treatment options becomes increasingly recognized.

Long-Term Efficacy of VYKAT XR for Prader-Willi Syndrome
- Significant Treatment Effects: In a two-year study, participants resuming VYKAT XR showed durable improvements in hyperphagia and behavioral symptoms, reinforcing the drug's efficacy and safety as a long-term treatment for Prader-Willi syndrome (PWS).
- Clinical Trial Data: Results from Study C614 involving 77 participants indicated that those who resumed treatment experienced significant recovery in hyperphagia symptoms, while those on continuous therapy maintained notable improvements in hyperphagia and other PWS-related behaviors.
- Long-Term Follow-Up Study: Compared to 229 natural history controls, VYKAT XR demonstrated statistically significant improvements in hyperphagia scores at all evaluated time points over three years, highlighting the drug's sustained efficacy.
- Behavioral Improvement Analysis: Analysis of PWSP data from 105 VYKAT XR-treated participants revealed significant improvements across all six behavioral domains, further validating its potential application in PWS patients.

Neurocrine Biosciences Reveals Clinical Findings on CAH Treatment
- Clinical Findings: Neurocrine Biosciences announced results from a retrospective case series involving 15 patients with classic congenital adrenal hyperplasia (CAH) due to 11β-hydroxylase deficiency, demonstrating that treatment with CRENESSITY® (crinecerfont) led to significant reductions in androgen precursors and improved blood pressure, indicating the drug's potential in managing this rare CAH subtype.
- Hormonal Control Improvement: The study revealed that all patients with elevated baseline androgen levels experienced a decrease in steroid precursor levels to normal ranges after initiating CRENESSITY, with adult patients also showing improved blood pressure, underscoring the drug's efficacy in enhancing hormonal control.
- Clinical Significance: This case series provides critical clinical insights for managing patients with 11β-hydroxylase deficiency, aiding clinicians in treatment decisions amidst limited data, thus addressing a complex subgroup within classic CAH.
- Future Research Directions: Neurocrine emphasized its commitment to further exploring the application of CRENESSITY in classic CAH subtypes, reinforcing its dedication to advancing treatment options for patients with rare endocrine disorders.

CRENESSITY Shows Significant Clinical Effects in Patients with 11β-Hydroxylase Deficiency
- Significant Efficacy: In patients with 11β-hydroxylase deficiency, CRENESSITY treatment resulted in over 90% median reductions in 11-deoxycortisol and 11-deoxycorticosterone, demonstrating the drug's strong potential in hormone level control.
- Improved Medication Adherence: Among the 15 patients treated with CRENESSITY, 14 were able to reduce their total glucocorticoid dose, indicating the drug's effectiveness in reducing hormone dependency.
- Blood Pressure Improvement: Among patients receiving antihypertensive treatment, two were able to reduce or discontinue these medications, suggesting CRENESSITY's potential benefits in managing hypertension.
- Clinical Research Breakthrough: This retrospective case series provides initial clinical insights for patients with 11β-hydroxylase deficiency, highlighting the importance of CRENESSITY in treating classic congenital adrenal hyperplasia and promoting further research into this rare subtype.

Long-Term Efficacy of VYKAT XR in Treating Prader-Willi Syndrome
- Significant Treatment Effects: Participants who resumed VYKAT XR after a 16-week randomized withdrawal period demonstrated marked improvements in hyperphagia and behavioral symptoms as early as Week 13, with benefits sustained over two years, indicating the drug's long-term efficacy in Prader-Willi syndrome (PWS) patients.
- Clinical Trial Data Support: Three-year data for VYKAT XR showed statistically significant improvements in hyperphagia scores compared to controls from the natural history study, with treatment differences of 6.2, 6.5, and 6.2 points at Year 1, Year 2, and Year 3, respectively, highlighting the drug's sustained effectiveness.
- Comprehensive Behavioral Improvements: Participants who resumed VYKAT XR exhibited significant improvements across all six behavioral domains of PWS over two years, particularly in anxiety, compulsivity, and aggression, further validating the multidimensional efficacy of the drug.
- Ongoing Safety Monitoring: Throughout the clinical trials, long-term use of VYKAT XR did not result in severe adverse reactions, and participants' body mass index (BMI) remained relatively stable, demonstrating the drug's ability to effectively manage overall health while treating hyperphagia.
