The Ionis-HTTRx trial is a small safety study that aims to test a ‘huntingtin lowering’ therapy, called an antisense drug. The antisense drug specifically targets the huntingtin mRNA that inhibits and prevents the formation of huntingtin protein directly. This is the first human trial to target the underlying cause of HD, and has shown great promise in animal models. The drug will be administered via a needle inserted into the fluid-filled space below the lower spinal cord.
This study enrollment is now closed.
