💊 Real-World Evidence on Deutetrabenazine for Movement Symptoms in People with Huntington’s Disease
Chorea is a common movement symptom of Huntington’s disease (HD), but less is known about how treatments to reduce chorea perform in real-world clinical practice.
A new study has examined real-world treatment patterns, outcomes and tolerability of deutetrabenazine (DTBZ) in 80 people with HD-associated chorea.
Key Findings:
Chorea Improved
Among 50 patients with qualifying pre- and post-treatment Unified HD Rating Scale–Total Maximal Chorea (TMC) scores, the mean score decreased by 4.2 points post-treatment with DTBZ, with 84% experiencing an improvement in chorea associated with HD.
Improvements Occurred Across Treatment Groups
TMC scores decreased in patients who were new to treatment and those who switched from tetrabenazine (TBZ) to DTBZ.
Potential Benefit After Previous TBZ Treatment
Among seven patients who had previously stopped TBZ because it was ineffective, five experienced an improvement in TMC scores with DTBZ. However, the small sample size means these findings should be interpreted cautiously.
Generally Well Tolerated
One or more adverse events were recorded in 33.8% of patients, with sedation/fatigue among the most common.
Summary:
Overall, the findings from this article support DTBZ as a treatment option for HD-associated chorea, including for people with previous TBZ exposure. However, further research is needed to confirm these findings in larger and more diverse patient populations.
