Overview
The purpose of this trial is to evaluate safety, tolerability, pharmacokinetics and pharmacodynamic impact of PrP-siRNA in symptomatic prion disease patients.
Description
This is a first-in-human, open label, single ascending dose study in participants with prion disease. The study will consist of a screening period of up to 2 weeks, administration of a single intrathecal dose of PrP-siRNA, and a 24-week follow-up period. Multiple dose levels will be tested. This trial also includes an observational arm in which participants will not receive investigational drug, and will be followed for an 8-week period after baseline.
