What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are RO7268489, Ocrelizumab, or Placebo. The registry lists allocation as randomized. The main purpose of this study is to assess the how well it works of RO7268489 in adults with progressive multiple sclerosis (PMS) receiving ocrelizumab.
