A Study to Evaluate the Safety, Tolerability, and Exploratory Efficacy of IMS001 in Subjects With Multiple Sclerosis

Summary

This is a Phase 1 study of IMS001, given as a single dose to subjects with Multiple Sclerosis who experience inadequate response and/or intolerability to disease modifying treatments.
