Key clinical point: Switching to once every-6-weeks (QW6) dosing of natalizumab from a stable dosing of once every-4-weeks (QW4) was safe without any clinically meaningful loss of efficacy in most patients with relapsing-remitting multiple sclerosis (RRMS).
Major finding: The mean number of new or newly enlarging T2 hyperintense lesions at 72 weeks was 0.20 (95% CI 0.07-0.63) vs 0.05 (95% CI 0.01-0.22) with natalizumab QW6 vs QW4 dosing regimen, with two patients developing ≥25 lesions contributing to most of the excess lesions in the QW6 dosing regimen. The safety profile was similar for both the regimens.
Study details: Findings are from a phase 3b NOVA trial including 499 patients with RRMS on stable intravenous natalizumab QW4 dosing who were randomly assigned to continue QW4 (n = 248) or switch to QW6 (n = 251) natalizumab dosing.
Disclosures: This study was funded by Biogen. Five authors reported being current or former employees or holding stocks in Biogen, and some authors reported receiving consulting or speakers’ fees, personal compensation, or serving as a steering committee or advisory board member for various sources.
