Promising Data from Neurocrine Biosciences on INGREZZA for TD
Neurocrine Biosciences Unveils Groundbreaking Findings on Tardive Dyskinesia Treatment
Neurocrine Biosciences, Inc. (NASDAQ: NBIX) has recently shared compelling data regarding the efficacy of INGREZZA® (valbenazine) capsules in treating tardive dyskinesia (TD). In this long-term analysis, a significant number of participants achieved remission, showcasing the drug's effectiveness across various underlying psychiatric conditions.
Key Insights from the KINECT 4 Study
The data was derived from the KINECT 4 clinical trial, where patients who underwent 48 weeks of once-daily treatment with INGREZZA showed remarkable improvement. This analysis assessed participants on their progress based on the Abnormal Involuntary Movement Scale (AIMS), highlighting how many reached the proposed remission threshold.
Dr. Eiry W. Roberts, Chief Medical Officer at Neurocrine Biosciences, emphasized the importance of the findings, noting that they confirm INGREZZA as a viable long-term option for individuals grappling with TD, irrespective of their specific psychiatric diagnosis. The improvement in AIMS scores was significant, reflecting the drug's effectiveness even at lower dosages.
Details of Patient Outcomes
The study included 103 participants who completed the Week 48 assessments. The results indicated that:
- 59.2% of participants achieved remission from TD symptoms, including 58.6% on a 40 mg dosage and 59.5% on an 80 mg dosage.
- Both dosage groups experienced substantial reductions in AIMS scores, marking a significant drop from baseline levels.
- The remission rates exhibited consistent patterns across different psychiatric diagnoses, indicating the comprehensive effectiveness of the treatment.
Contributions to Ongoing Research
Neurocrine Biosciences also presented additional research at the corresponding conference, including insights into long-term improvements at various dosages. This reinforces the role of INGREZZA as a robust therapeutic option for patients suffering from TD.
Understanding Tardive Dyskinesia
Tardive dyskinesia is often associated with long-term use of antipsychotic medications. Characterized by uncontrollable movements, particularly in the face and torso, TD presents a significant challenge to those affected. Current understanding suggests that the irregular dopamine signaling in the brain is a primary factor in developing this condition.
It's estimated that TD impacts a sizable population, with over 800,000 adults affected in the U.S. alone. This makes the research and development of effective treatments like INGREZZA critical for improving patients' quality of life.
