Complement Inhibitors in NMOSD

Author(s)Sean Pittock, MD

Key Takeaways

Ravulizumab, a complement inhibitor, is FDA-approved for NMOSD, offering a longer half-life than eculizumab, allowing for extended dosing intervals.
The standard dosing regimen for ravulizumab includes an initial loading dose followed by maintenance doses every eight weeks.
Recent 138-week extension data show sustained efficacy and safety of ravulizumab, with no new safety signals observed.
Ravulizumab's development highlights its role in the evolving NMOSD treatment landscape, providing a more convenient option for patients.
