Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of ION464 Administered to Adults With Multiple System Atrophy (HORIZON)

Summary

The primary objectives are to evaluate the safety and tolerability of multiple doses of ION464 administered via intrathecal (IT) injection (Part 1) and to evaluate the long-term safety and tolerability of ION464 (Part 2) in participants with multiple system atrophy (MSA). The secondary objectives are to evaluate the pharmacodynamic (PD) effect of ION464 on the level of a potential biomarker of target engagement (Parts 1 and 2) and to evaluate the pharmacokinetic (PK) profile of ION464 in serum (Part 1).
