Neurocrine Biosciences, Inc. today announced that the complete study results from its Phase 3 KINECT™-HD study investigating valbenazine for the treatment of chorea associated with Huntington’s disease (HD) has been published in The Lancet Neurology online edition and will appear in the June 2023 print issue. The study met its primary and secondary endpoints, demonstrating a reduction in chorea symptoms associated with HD and improvement of overall chorea severity as noticed by clinicians and patients, with improvement seen as early as Week 2 of the initial dose in the 12-week study.
The KINECT-HD randomized double-blind, placebo-controlled Phase 3 study was conducted with 128 participants at 46 Huntington Study Group (HSG)–credentialed sites in North America.

The primary endpoint was a reduction in severity of chorea, the cardinal motor feature in HD, as measured by change in the HSG-developed Unified Huntington’s Disease Rating Scale (UHDRS®) Total Maximal Chorea (TMC) score from baseline to the average score at weeks 10 and 12. The TMC score is part of the motor assessment of the UHDRS that measures chorea.
