Genetic Therapy Reduces Key Protein in Huntington’s Disease
Key clinical point: A genetic therapy reduced levels of a harmful protein in the cerebrospinal fluid of patients with Huntington’s disease.
Major finding: Mean reductions of between 20% and 42% of cerebrospinal fluid concentrations of mutant huntingtin with treatment versus an increase of 10% in the placebo arm.
Study details: A randomized, double-blinded, multiple-ascending-dose, placebo-controlled trial enrolling 46 patients with early Huntington’s disease in three countries.
Disclosures: The study was funded by Ionis Pharmaceuticals and F. Hoffmann–La Roche, and most of the authors, including Dr. Tabrizi, reported financial relationships with one or both entities.
