Neurocrine Biosciences Presents INGREZZA® (valbenazine) Data on Sustained Treatment Response at Psych Congress 2022
On September 19, 2022, Neurocrine Biosciences (Nasdaq: NBIX) shared data at the Psych Congress 2022, showcasing the long-term efficacy of INGREZZA (valbenazine) in treating tardive dyskinesia (TD). The post hoc analysis from the KINECT 4 study revealed that patients' response rates to treatment increased significantly over 48 weeks. Specifically, AIMS improvement rates rose from 39% at week 8 to 86% at week 48. Adverse events were mainly urinary tract infections (8.5%) and headaches (5.2%). This data underscores INGREZZA's lasting benefits for patients suffering from TD.
- 86% of patients reached ≥50% AIMS improvement by week 48, showing significant treatment efficacy.
- 95% of patients who improved by week 8 maintained that improvement at week 48.
- AIMS improvement of ≥70% increased from 17% at week 8 to 52% at week 48.
- The global response rate increased substantially for both clinical and patient assessments.
- Most common treatment-emergent adverse event was urinary tract infection (8.5%).
SAN DIEGO, Sept. 19, 2022 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced that it will present data demonstrating sustained improvements with long-term INGREZZA® (valbenazine) capsules treatment in adults with tardive dyskinesia (TD) at the Psych Congress 2022 scientific meeting being held September 17-20.
Neurocrine Biosciences, the leading neuroscience-focused company in the treatment of TD, will present findings from a post hoc analysis of the 48-week, open-label KINECT 4 study of INGREZZA evaluating treatment response patterns (Poster #75; Sustained Treatment Response with Long-Term Valbenazine in Patients with Tardive Dyskinesia). The analysis, which included treatment completers of KINECT 4 (n=103), found that the proportion of patients meeting rigorous response criteria increased over time:
- The proportion of participants who reached a ≥50 percent Abnormal Involuntary Movement Scale (AIMS) improvement from baseline increased from week 8 to week 48 (39 percent [n=40] to 86 percent [n=89] of participants, respectively).
- Of the 40 participants (39 percent) with AIMS ≥50 percent response at week 8, 95 percent (38 participants) also met this threshold at week 48, demonstrating a sustained response.
- An increase in proportion of participants that met the rigorous 70 percent or more AIMS improvement from baseline increased from week 8 to week 48 (17 percent [n=18] to 52 percent [n=54] of participants, respectively).
- Rates of participants meeting the defined global response threshold (rating of "much improved" or "very much improved") increased from week 8 to week 48, from 50 percent to 92 percent for Clinical Global Impression of Change-Tardive Dyskinesia (CGI-TD) and 53 percent to 88 percent for Patient Global Impression of Change (PGIC), respectively.
"TD can disrupt many aspects of day-to-day life, and adequate assessment, diagnosis, and continued management of symptoms are of key importance," said Eiry W. Roberts, MD, Chief Medical Officer at Neurocrine Biosciences. "These data demonstrate that a vast majority of participants taking INGREZZA obtained substantial and sustained TD improvement throughout the study, and the proportion of patients achieving symptom relief increased with continued treatment over time."
The most common treatment-emergent adverse events (TEAE) reported in KINECT 4 (≥5 percent of all INGREZZA-treated patients after week 4) were urinary tract infection (8.5 percent) and headache (5.2 percent).

About Tardive Dyskinesia (TD)
Tardive dyskinesia (TD) is a movement disorder that is characterized by uncontrollable, 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 (like antipsychotics) that help control dopamine receptors in the brain. Taking antipsychotics commonly prescribed to treat mental illnesses such as depression, bipolar disorder, schizophrenia and schizoaffective disorder, and certain medications to treat upset stomach, nausea and vomiting 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 severe and are often persistent and irreversible. TD is estimated to affect approximately 600,000 people in the U.S.
About INGREZZA® (valbenazine) Capsules
INGREZZA, a selective vesicular monoamine transporter 2 (VMAT2) inhibitor, is an FDA-approved product indicated for the treatment of adults with tardive dyskinesia, a condition associated with uncontrollable, abnormal, and repetitive movements of the face, torso and/or other body parts.
INGREZZA is thought to work by reducing the amount of dopamine released in a region of the brain that controls movement and motor function, helping to regulate nerve signaling in adults with tardive dyskinesia. VMAT2 is a protein in the brain that packages neurotransmitters, such as dopamine, for transport and release in presynaptic neurons. INGREZZA, developed by Neurocrine Biosciences, is novel in that it selectively inhibits VMAT2 with no appreciable binding affinity for VMAT1, dopaminergic (including D2), serotonergic, adrenergic, histaminergic, or muscarinic receptors. Additionally, INGREZZA can be taken for the treatment of tardive dyskinesia as one capsule, once-daily, together with most psychiatric medications such as antipsychotics or antidepressants.
