What This Trial Is Studying

The purpose of this study is to evaluate the safety, tolerability, efficacy, and drug levels of CC-97540 in participants with Relapsing Forms of Multiple Sclerosis (RMS), Progressive Forms of Multiple Sclerosis (PMS) or Refractory Myasthenia Gravis (MG).

Eligibility Snapshot
