About This Trial
The primary purpose of the study is to evaluate the safety and tolerability of a single-ascending intravenous (IV) dose (Part 1), a single-ascending subcutaneous (SC) dose (Part 2), and multiple ascending SC doses (Part 3), and multiple-ascending SC doses following a single IV dose (Part 4) of RO7121932 in participants with multiple sclerosis (MS). Only Parts 1 and 2 of the study will be conducted in the United States, whereas Parts 1, 2, 3, and 4 will be conducted in all other participating countries outside the United States.
