- Primary Outcome Measures
Name Time Method Main Objective: To assess the effects of ACR16 on voluntary movement function in HD patients, defined as the sum score of items 4-10 and 13-15 of the UHDRS motor assessment (a modified motor score mMS ) at 26 weeks of treatment.;Secondary Objective: Secondary objectives are to assess the effects of ACR16 on Clinical Global Impression(CGI) , cognitive function, behaviour and symptoms of depression and anxiety at 26 weeks of treatment and to assess the safety and tolerability of ACR16.;Primary end point(s): The primary variable is the change in mMS (items 4-10 and 13-15 of the UHDRS [Unified Huntington's Disease Rating Scale] motor assessment) from baseline to the week 26 assessment.
