Key Terms

tardive dyskinesia, vmat2 inhibitors, abnormal involuntary movement scale (aims), delphi panel, +3 more

7 terms

tardive dyskinesia medical

"structured approach to tardive dyskinesia screening, diagnosis and treatment in long-term care"

A chronic movement disorder marked by repetitive, involuntary motions—often of the face, tongue, or limbs—that can develop after long-term use of certain psychiatric or neurological medications. It matters to investors because the condition creates medical need, regulatory scrutiny, potential for expensive treatments or liability, and can shape the commercial value of drugs in development or on the market; think of it as a persistent side effect that can change a drug’s price tag and sales prospects.

vmat2 inhibitors medical

"support evidence-based diagnosis and appropriate use of VMAT2 inhibitors."

VMAT2 inhibitors are a class of medicines that reduce the amount of certain brain chemicals, especially dopamine, that cells release by blocking the transporter that packages them for release. Think of them as turning down a faucet that supplies a signaling chemical; that change can ease involuntary movements and other symptoms in neurological conditions. Investors watch VMAT2 inhibitors because regulatory approvals, safety profiles, patent life and market demand determine a drug’s commercial potential and company valuation.

abnormal involuntary movement scale (aims) medical

"Use of the Abnormal Involuntary Movement Scale (AIMS) for screening and assessing TD."

AIMS is a standardized clinical rating scale doctors use to track involuntary muscle movements, often caused by certain psychiatric or neurological drugs; think of it as a thermometer for uncontrollable facial and body motions. For investors, AIMS scores matter because rising or persistent scores can signal drug safety problems, affect clinical trial outcomes, regulatory reviews and labeling, and ultimately influence a company’s product value and stock outlook.

delphi panel technical

"Developed through a multidisciplinary Delphi panel, the recommendations address persistent gaps"

A Delphi panel is a structured process that gathers and refines opinions from a group of independent experts through multiple anonymous rounds of surveys and feedback, aiming to reach a clearer collective judgment. For investors it matters because it turns scattered expert views into a more reliable forecast or risk assessment—like repeatedly polling specialists and tuning answers until a clearer signal emerges—helping weigh prospects for new products, regulations, or market trends.

polypharmacy medical

"advanced age, polypharmacy and complex comorbidities."

Polypharmacy is when a person regularly takes multiple medications at the same time, often prescribed by different doctors or bought over the counter; the exact number that qualifies can vary. It matters to investors because combining many drugs raises the risk of side effects, drug interactions, and regulatory scrutiny, which can change a medicine’s market value, affect demand for safer alternatives or monitoring tools, and influence clinical trial results—like juggling many balls where one misstep changes the outcome.

post-hoc analysis technical

"presented a first-of-its-kind post-hoc analysis from the KINECT‑PRO study"

Post-hoc analysis is an examination of data carried out after an experiment, trial, or reporting period to look for patterns or explanations that were not specified beforehand. It matters to investors because such findings can suggest new opportunities or risks but are more likely to be chance results than preplanned conclusions, so they require independent confirmation before being treated as reliable — like noticing a pattern on a map after a trip and then testing it on the next journey.

phase 4 medical

"*Phase 4 KINECT-PRO Findings Reinforce Significance of Expert Consensus Guidelines"

Phase 4 is the stage after a drug or vaccine has been approved and is sold to the public, where regulators and companies keep watching how it performs in the real world to detect rare side effects, long‑term effects, or differences in effectiveness across different groups. Think of it as ongoing quality control for a product already on shelves; results can prompt label changes, safety warnings, sales impacts or recalls, all of which matter to investors evaluating risk and future revenue.

• 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 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 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.  

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. INGREZZA and INGREZZA SPRINKLE dosages approved for use are 40 mg, 60 mg and 80 mg capsules.
