Long-term Effect of Ofatumumab Treatment on Serum Neurofilament Light Chain Levels and NEDA-3 Status in Patients With RMS: Results From ASCLEPIOS I/II and ALITHIOS
Multiple Sclerosis
P6 - Poster Session 6 (5:30 PM-6:30 PM)

In ASCLEPIOS I/II, OMB lowered sNfL levels vs TER over 96 weeks and increased the likelihood of achieving NEDA-3 in Years 1 and 2 (Y1/Y2).
To assess the long-term effect of ofatumumab (OMB; anti-CD20 monoclonal antibody) on serum neurofilament light chain (sNfL) levels and 3-parameter no evidence of disease activity (NEDA-3) in patients with relapsing multiple sclerosis receiving continuous OMB and those converted from teriflunomide (TER) in ASCLEPIOS I/II (core; NCT02792218/NCT02792231) and ALITHIOS (open-label extension; NCT03650114).
We analyzed cumulative data from patients randomized to OMB/TER (946/936) in ASCLEPIOS I/II (pooled) who continued OMB (OMB-OMB; 690) or converted from TER to OMB (TER-OMB; 677) in ALITHIOS. Between-group comparisons of geometric mean sNfL levels over time and proportion of patients achieving NEDA-3 were evaluated.
In ASCLEPIOS I/II, sNfL levels (pg/mL) were reduced with OMB vs TER (month [M] 12, 8.03 vs 10.25; M24, 7.96 vs 9.97; both p<0.001). Continuous OMB treatment maintained low sNfL levels in ALITHIOS (M24, 8.50). Converting from TER to OMB significantly reduced sNfL levels vs OMB-OMB up to M6 after switch (9.07 vs 8.31; p<0.001). Low sNfL levels were observed in both groups from M12 onward (M24, 8.23 vs 8.50). In ASCLEPIOS I/II, OMB treatment resulted in an ~3-fold higher likelihood of achieving NEDA-3 vs TER during Y1 (48% vs 25.2%; OR [95% CI], 3.39 [2.71-4.25]; p<0.001) and 10-fold higher likelihood during Y2 (85% vs 38.4%; 10.09 [7.82-13.02]; p<0.001). In ALITHIOS, ~8/10 patients in OMB-OMB and 6/10 patients in TER-OMB achieved NEDA-3 in Y1 (85.8% vs 59.5%; 4.50 [3.40-5.94]; p<0.001). NEDA-3 achievement during Y2 was similar in OMB-OMB and TER-OMB (86.4% vs 90.4%; 1.55 [1.07-2.22]; p=0.019).
A near complete and sustained suppression of disease activity was achieved with early and continuous use of OMB, and a rapid reduction in disease activity followed conversion from TER to OMB.
