Dyskinesia

Early initiation of opicapone significantly reduces OFF time and enhances ON time in patients with recently diagnosed Parkinson's disease, improving overall treatment outcomes.

A recent phase 2b study reveals mesdopetam's potential in reducing dyskinesia severity in Parkinson disease, despite no significant ON time improvement.

Use of immediate-release amantadine as an add-on to levodopa reduced peak-dose dyskinesia incidence in patients with early Parkinson disease, according to results from the phase 2 PREMANDYSK trial.

Real-world data from Teva Pharmaceuticals’ IMPACT-TD Registry showed that deutetrabenazine and its extended-release formulation led to significant reductions of involuntary movements and improved quality of life for adults with tardive dyskinesia.

Valbenazine shows significant improvements in physical, social, and emotional outcomes for tardive dyskinesia patients, as revealed in a recent study.

Pooled analysis from KINECT-3 and KINECT-4 confirms valbenazine’s long-term safety and efficacy in managing tardive dyskinesia in elderly patients.

The newly added tablet strengths allow for greater flexibility when selecting or adjusting dosing for deutetrabenazine.

Leslie Citrome, MD, MPH, clinical professor of psychiatry and behavioral sciences at New York Medical College, shared his reaction to the recently approved new sprinkle formulation of valbenazine for patients with tardive dyskinesia.

The original approval for chorea associated with Huntington disease was based on the phase 3 KINECT-HD study, an 128-patient cohort trial in which valbenazine met its primary end point.

On average, clinician-rated TD severity, measured by AIMS, and patient-reported assessment of the physical, social and emotional impact of TD, measured by TDIS, decreased with one-capsule, once-daily valbenazine over 48 weeks.

Teva’s VMAT2 inhibitor was previously approved in a twice-daily formulation. The once-daily extended-release treatment, marketed as Austedo XR, is expected to be available later in 2023 in doses of 6 mg, 12 mg, and 24 mg.

At weeks 54, 106, and 145, most of both age groups achieved treatment success on both the CGIC and PGIC, with numerically higher percentages observed in younger vs older participants.

Tardive dyskinesia can present many challenges in its treatment and can be difficult to differentiate from similar disorders.

The chief medical officer of Neurocrine Biosciences spoke about how long-term data on valbenazine (Ingrezza) has helped shape the understanding of the effect tardive dyskinesia can have on patients, and how it can inform better utilization of the medication.
