• A diagnosis of relapsing MS (RMS) in accordance with the revised 2017 McDonald Criteria and one of the following:
o At least two documented clinical relapses within the last 2 years or one documented clinical relapse within 12 months of screening (but not within the 30 days prior to screening)
o Documented evidence of the presence of at least one T1 Gd+ lesion on MRI in the 6 months prior to randomization (may include the screening MRI)
