Neurocrine Validates Patient-Reported Outcome Scale for Tardive Dyskinesia Treatment
Event summary
- Neurocrine Biosciences published research in The Journal of Clinical Psychiatry defining a clinically meaningful improvement threshold of four points on the Tardive Dyskinesia Impact Scale (TDIS).
- The TDIS, developed in partnership with neurology and psychiatry thought leaders, is the first psychometrically validated patient-reported outcome measure for tardive dyskinesia (TD).
- The publication supports previously reported results from the KINECT-PRO™ Phase 4 study, demonstrating patient-reported improvements with INGREZZA® (valbenazine) across physical, social, and emotional functioning.
- The KINECT-PRO™ study involved 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.
The big picture
Neurocrine's validation of the TDIS represents a shift towards patient-centric drug development in the treatment of TD, a condition affecting an estimated 800,000 adults in the U.S. This focus on patient-reported outcomes is increasingly important for demonstrating the real-world value of therapies and securing favorable reimbursement. The TDIS's unique validation and adoption could create a barrier to entry for competitors seeking to address this underserved market.
What we're watching
- Adoption Rate
- The extent to which clinicians and researchers adopt the TDIS as a standard measure for assessing TD treatment response will influence Neurocrine's ability to demonstrate value and potentially impact reimbursement decisions.
- Competitive Landscape
- Competitors may attempt to develop alternative patient-reported outcome measures, potentially challenging the TDIS's established position and Neurocrine's market advantage.
- Clinical Utility
- Further research is needed to determine how the TDIS can be best integrated into clinical practice to optimize patient care and inform treatment decisions beyond the KINECT program.
