INGREZZA showed higher rates of long-term treatment continuation and lower switching between medications compared to AUSTEDO XR (deutetrabenazine) in a real-world claims analysis among adults with tardive dyskinesia Higher continuation with INGREZZA was observed early in treatment and persisted across a six‑month follow‑up period SAN DIEGO , April 14, 2026 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the presentation of new real-world evidence demonstrating that adult patients with tardive dyskinesia receiving INGREZZA ® (valbenazine) capsules showed higher treatment persistence compared to those on AUSTEDO XR (deutetrabenazine). The findings are being presented at the Academy of Managed Care Pharmacy 2026 Annual Meeting in Nashville. This retrospective, real-world claims analysis is the first published study to directly compare treatment persistence — defined as remaining on therapy without discontinuation or switching medications — between INGREZZA and AUSTEDO XR in matched tardive dyskinesia (TD) patient cohorts. Over a six-month follow-up period, patients treated with INGREZZA demonstrated statistically greater treatment continuation and lower switching rates than those receiving AUSTEDO XR. Differences in treatment persistence emerged early and were sustained throughout the six-month period, highlighting durable treatment continuation patterns. "Treatment discontinuation is common in psychiatric populations, and interruption of VMAT2 inhibitor therapy can lead to recurrence of tardive dyskinesia symptoms, associated increased disease burden and worsened quality of life," said Sanjay Keswani, M.D., Chief Medical Officer, Neurocrine Biosciences. "As the first real-world comparison of treatment persistence between INGREZZA and AUSTEDO XR, these findings highlight a higher persistence pro INGREZZA and provide real-world evidence to inform treatment decision-making in clinical practice." The analysis used IQVIA's U.S. Longitudinal Access and Adjudication Data (LAAD), integrating pharmacy and medical claim information. The study period ranged from September 1, 2022 to March 31, 2025 (30 months), including adult patients with TD who initiated either INGREZZA or AUSTEDO XR between March 1, 2023 and September 30, 2024 (18 months). Eligible patients had ≥1 pharmacy claim during both the 6-month baseline and follow-up periods, ≥1 claim for either INGREZZA or AUSTEDO XR during the selection period and ≥1 claim with a diagnosis of TD during the study period. Ultimately, the analysis included 2,988 eligible patients split between cohorts who started on either INGREZZA (n=1,494) or AUSTEDO XR (n=1,494), using propensity score matching (1:1) to create balanced cohorts accounting for baseline demographics, comorbidities, psychiatric conditions and antipsychotic use. Over the 6-month follow-up period: Significantly more patients persisted with their initial TD therapy in the cohort who started on INGREZZA (55.6%) compared to those who started on AUSTEDO XR (48.1%). Switching to another TD therapy at any time during the follow-up period was significantly less frequent in the INGREZZA cohort (7.7%) compared to AUSTEDO XR (11.2%). The median time to discontinuation or switch from the initial therapy was 129 days for the AUSTEDO XR cohort, while the median was not reached for the INGREZZA cohort (>180 days), indicating significantly longer time to discontinuation or switch.

"Claims-based analyses offer critical insight into treatment patterns for tardive dyskinesia, where staying on therapy is key to controlling symptoms that can disrupt daily life. By applying a robust methodological approach to real-world data, providers can better understand persistence and help inform more effective treatment strategies for patients," said Mercedes Perez-Rodriguez, M.D., Ph.D., Associate Professor of Psychiatry, Icahn School of Medicine at Mount Sinai, New York. Dr. Perez-Rodriguez is a paid consultant of Neurocrine Biosciences, Inc. and has received grant funding from Neurocrine Biosciences, Inc. Findings from this analysis are built on prior clinical evidence demonstrating the impact of INGREZZA on TD symptoms and patient-reported outcomes. In clinical studies, including the Phase 4 KINECT-PRO™ study , treatment with INGREZZA improved TD severity and was associated with meaningful improvements in patient-reported outcomes, including physical, social and emotional functioning. In addition, in the KINECT-PRO study, 57.8% of patients who continued treatment with INGREZZA achieved symptomatic remission after 24 weeks, defined as minimal or no involuntary movements (Abnormal Involuntary Movement Scale [AIMS] score ≤1 in each body region [items 1-7]). Together, the real-world and clinical evidence underscore the importance of sustained treatment of TD and the utility of INGREZZA as a first-line therapy for the condition. Additional presentation at the Academy of Managed Care Pharmacy 2026 Annual Meeting includes: Valbenazine Improves Physical, Social, and Emotional Impacts on the Tardive Dyskinesia Impact Scale (TDIS): Post-Hoc Analyses of KINECT-PRO Data About Tardive Dyskinesia Tardive dyskinesia (TD) is a movement disorder that is characterized by uncontrolled, abnormal and repetitive movements of the face, torso and/or other body parts, which may be disruptive and negatively impact patients. The condition is associated with taking certain kinds of mental health medicines (antipsychotics) that help control dopamine receptors in the brain. Taking antipsychotics commonly prescribed to treat mental illnesses such as major depressive disorder, bipolar disorder, schizophrenia and schizoaffective disorder and other prescription medicines (metoclopramide and prochlorperazine) used to treat gastrointestinal disorders are associated with TD. In patients with TD, these treatments are thought to result in irregular dopamine signaling in a region of the brain that controls movement. The symptoms of TD can be mild to severe and are often persistent and irreversible. TD is estimated to affect at least 800,000 adults in the U.S. About the KINECT-PRO™ Phase 4 Study The KINECT-PRO™ Phase 4, open-label study was designed to evaluate patient-reported outcomes on the use of INGREZZA ® (valbenazine) capsules in a tardive dyskinesia (TD) patient population reflective of real-world clinical practice. Participants had at least mild TD, were aware of and experiencing at least mild distress from their abnormal, involuntary movements and had a clinical diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder or major depression. The KINECT-PRO study included a four-week screening period, a 24-week treatment period during which participants received 40 mg of INGREZZA once-daily for the first four weeks, followed by flexible dosing of 40 mg, 60 mg or 80 mg once-daily based on individual treatment needs and a two-week safety follow-up period. Baseline socio-demographic and clinical characteristics of the participants were broadly similar to those of the KINECT ® 3 and KINECT ® 4 studies. KINECT-PRO is the first and only study to specifically evaluate and demonstrate patient-reported improvement with vesicular monoamine transporter 2 inhibitor treatment on TD using multiple clinically validated scales, including the Tardive Dyskinesia Impact Scale (TDIS™). The TDIS is the only patient-reported outcome instrument designed for and validated in tardive dyskinesia patients that measures the physical, social and emotional impact of the involuntary movements of the condition. About INGREZZA ® (valbenazine) Capsules and INGREZZA ® SPRINKLE (valbenazine) Capsules INGREZZA is a selective vesicular monoamine transporter 2 (VMAT2) inhibitor approved by the U.S. Food and Drug Administration for the treatment of adults with tardive dyskinesia and the treatment of chorea associated with Huntington's disease (HD). Only INGREZZA offers a therapeutic dose from day one with no required titration. INGREZZA, developed by Neurocrine Biosciences, selectively inhibits VMAT2 with no appreciable binding affinity for VMAT1, dopaminergic (including D2), serotonergic, adrenergic, histaminergic or muscarinic receptors. While the specific way INGREZZA works to treat TD and HD chorea is not fully understood, INGREZZA is unique in that it selectively and specifically targets VMAT2 to inhibit the release of dopamine, a chemical in the brain that helps control movement. INGREZZA is believed to reduce extra dopamine signaling, which may lead to fewer uncontrollable movements. INGREZZA is studied across the widest range of patients. It is always one capsule, once daily and can be taken together with most stable mental health regimens such as antipsychotics or antidepressants. Only INGREZZA offers the benefit of a sprinkle formulation, INGREZZA SPRINKLE, for those who experience dysphagia, have difficulty swallowing or prefer not to swallow a pill.

Expert panel establishes structured approach to tardive dyskinesia screening, diagnosis and treatment in long-term care, including use of VMAT2 inhibitors New post-hoc KINECT‑PRO™ analysis in adults aged 65 years and older demonstrates clinically meaningful patient-reported improvements in tardive dyskinesia impact with INGREZZA® (valbenazine) capsules, reinforcing expert panel recommendations SAN DIEGO, March 26, 2026 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced the presentation of the first expert consensus recommendations focused on screening, diagnosis and treatment of tardive dyskinesia among older adults in long-term care settings. Developed through a multidisciplinary Delphi panel, the recommendations address persistent gaps in recognizing and managing tardive dyskinesia in this higher-risk population. Findings were presented at the Society for Post-Acute and Long-Term Care Medical Association (PALTmed) PALTC26 Annual Conference in Anaheim, Calif. The company also presented a first-of-its-kind post-hoc analysis from the KINECT‑PRO™ study demonstrating meaningful improvements in patient‑reported tardive dyskinesia (TD) impact among adults aged 65 years and older treated with INGREZZA® (valbenazine) capsules. This analysis adds to the growing body of evidence supporting the appropriateness, efficacy, tolerability and established safety profile of INGREZZA in this patient population. "To date, there has been limited practical guidance tailored specifically to the screening, diagnosis and treatment of tardive dyskinesia in the long-term care setting," said Sanjay Keswani, M.D., Chief Medical Officer, Neurocrine Biosciences. "The consensus recommendations provide structured guidance for clinicians caring for residents in these environments, and the KINECT-PRO findings demonstrate clinically meaningful patient-reported improvements in the impact of tardive dyskinesia with INGREZZA in adults aged 65 years and older. Together, this guidance and evidence help support more informed treatment decisions in this population that may be at higher risk for tardive dyskinesia." Older adults in long-term care are at an elevated risk for TD due to prolonged exposure to dopamine receptor blocking agents, advanced age, polypharmacy and complex comorbidities. Recognition and management may be further complicated in residents who are non-ambulatory, cognitively impaired or unable to reliably report symptoms. The Delphi panel was convened to develop recommendations that reflect this clinical complexity and support a more consistent, structured approach to TD care. "Residents in long-term care settings often present with overlapping medical and psychiatric complexities that can make tardive dyskinesia difficult to consistently recognize and manage," said Amita Patel, M.D., the poster's lead author and psychiatrist at the Joint Township District Memorial Hospital in St. Mary's, Ohio. "Through this process, the panel reached clear consensus on practical, implementable recommendations that support evidence-based diagnosis and appropriate use of VMAT2 inhibitors. These recommendations provide clinicians with a structured framework to guide screening and treatment decisions to help improve outcomes for this especially vulnerable population." Screening and Diagnosing TD in Long-Term Care Settings Requires a Holistic Approach The panel identified key considerations to support routine and consistent TD screening in long-term care settings. These include: Use of the Abnormal Involuntary Movement Scale (AIMS) for screening and assessing TD. Quarterly screening for residents treated with dopamine receptor blocking agents, the primary cause of TD. Regular assessment of the impact of TD on residents' well-being, including feedback from residents, family members, caregivers and the broader care team. Treatment Selection Should Consider Relevant Patient Factors Panelists also reached consensus that TD should be treated with a vesicular monoamine transporter 2 (VMAT2) inhibitor in long-term care settings and identified several treatment-selection factors particularly relevant in these environments. These include: Formulation flexibility for residents who experience dysphagia or difficulty swallowing. Simplified administration, including the availability of a therapeutic starting dose. Consideration of polypharmacy and potential drug-drug interactions. Availability of clinical data in adults aged 65 years and older. These considerations underscore the importance of selecting a therapy with a clinical profile and administration characteristics that align with the needs of long-term care residents. INGREZZA is approved for the treatment of adults with TD and, among approved VMAT2 inhibitors: has been studied extensively in adults aged 65 years and older. is the only VMAT2 inhibitor without a cautious dosing recommendation in this population. is the only treatment that offers a therapeutic dose from day one with no required titration. is available in a sprinkle formulation. has a safety profile in adults aged 65 years and older that is consistent with that observed in patients younger than 65 years of age.* Phase 4 KINECT-PRO Findings Reinforce Significance of Expert Consensus Guidelines A post-hoc analysis of the KINECT-PRO study complements the consensus recommendations by demonstrating the real-world impact of INGREZZA treatment in older adults. KINECT-PRO is the first and only clinical study to specifically evaluate and investigate patient-reported improvement with INGREZZA for TD using multiple validated scales, including the Tardive Dyskinesia Impact Scale (TDIS™). In adults aged 65 and older, once-daily INGREZZA was associated with robust patient-reported improvements in TD symptoms, quality of life and functional impairment at Week 24. Patient-reported outcomes also demonstrated reduced social and emotional burden, with improvements in total TDIS scores exceeding the established threshold for clinically meaningful change.

About the Tardive Dyskinesia Impact Scale The Tardive Dyskinesia Impact Scale (TDIS™) is the only patient-reported outcome instrument designed for and validated in tardive dyskinesia patients that measures the physical, social and emotional impact of the involuntary movements of the condition. It was developed by Neurocrine Biosciences from qualitative studies and Phase 3 trials of INGREZZA for the treatment of TD (KINECT® 3 and KINECT® 4) as a comprehensive measure of impact and burden of TD from a patient's perspective. The TDIS consists of 11 questions evaluating physical and socio-emotional impact. Six scales are assessed: mouth/throat, dexterity, mobility, pain, social and emotional. The TDIS allows people with TD to rate how their symptoms affect daily activities and how their uncontrollable movements make them feel. The questionnaire captures relevant information about the impact of TD to provide a more holistic assessment of the condition. Validation of this scale was published in the Journal of Patient-Reported Outcomes.
