Real-World Data (RWD) exploring the natural history of MS suggested that relapses do not significantly influence the progression of irreversible disability. Disability progression independent of relapses activity (PIRA) has been confirmed as a frequent relapsing-remitting multiple sclerosis (RRMS) phenomenon based on Randomized Clinical Trials (RCT). Recently, RWD demonstrated that the absence of markers of inflammation (No Evidence of Disease Activity (NEDA) at 2 years did not predict long-term stability. Silent progression has been proposed to describe the insidious disability that accrues many patients who satisfy traditional criteria for relapsing-remitting MS. In this study, the investigators would like to evaluate the occurrence of the SPMS in a population of RRMS patient with an Highly Active Treatment (HAT).
