What is the long-term safety and efficacy of satralizumab in patients with NMOSD who completed the pivotal SAkuraSky and SAkuraStar phase 3 trials?
Does rituximab or dimethyl fumarate better reduce astrocytic injury biomarkers and progression independent of relapse/MRI activity in RRMS?
RIFUND-MS
Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing-Remitting MS
Bottom Line: In RRMS, DMF but not RTX significantly reduced serum GFAP over 2 years, and RTX was associated with 3-fold higher risk of PIRMA despite superior MRI suppression. These findings challenge the assumption that MRI efficacy equals neuroprotection, and implicate GFAP as a clinically meaningful biomarker of DMT neuroprotective effects.
