It will also inform about the safety of pridopidine.\n\nThe main questions the study aims to answer are:\n\nDoes pridopidine slow the overall worsening of HD over 1 year? Does pridopidine slow the worsening of specific aspects of HD over 1 year, namely the clinical progression, the ability to perform daily life activities (functional capacity), the mind's ability to process information (cognition), working of the muscles (motor function), and quality of life?\n\nResearchers will compare the drug pridopidine to a placebo (a look-alike substance that contains no drug) to see if pridopidine works better than placebo to treat HD. During the first year of the study, participants will have the same chance to receive either pridopidine or placebo.\n\nParticipants will:\n\nTake 1 pridopidine or placebo capsule twice daily for 12 months. Visit the clinic 6 times within 1 year for checkups and tests.\n\nAll participants who complete this 1-year placebo-controlled study period will roll over into an additional 2-year study period during which all participants will receive pridopidine treatment, including participants who had received placebo during the first year. During this additional 2-year treatment period participants will visit the clinic a total of 6 times for checkups and tests.",[59],"Huntington Disease","NOT_YET_RECRUITING","2026-05-29",{"date":63,"type":64},"2026-06-02","ACTUAL",{"date":66,"type":53},"2026-06",{"date":68,"type":53},"2030-06",{"name":5,"class":6}]
