NfL as a Predictor of GdE Lesions in Patients With Relapsing Multiple Sclerosis Treated With Ozanimod in the Phase 2 RADIANCE Trial
Multiple Sclerosis
P1 - Poster Session 1 (8:00 AM-9:00 AM)
3-012

In multiple sclerosis (MS) patients, increased blood and cerebrospinal fluid neurofilament light chain concentration may be a biomarker for neurologic damage and disease activity.

To evaluate relationships between plasma neurofilament light chain (pNfL) and gadolinium-enhancing (GdE) lesion count in patients with relapsing multiple sclerosis (RMS) receiving ozanimod 0.92 mg in the phase 2 RADIANCE trial (NCT01628393).

pNfL was measured at baseline and weeks 4, 12, and 24 using Simoa Nf-light digital immunoassay. GdE lesion counts were assessed from available MRI scans at baseline and weeks 8, 12, 16, 20, and 24. Predictive modelling was performed using penalized logistic regression on 100 bootstrap samples.

A pNfL decrease was observed at week 4 (median [Q1, Q3] % change from baseline: −7.891 [−18.933, 14.486]), with further decreases through week 24 (−15.883 [−32.039, 1.759], P<0.0001). GdE lesion counts were lower in patients receiving ozanimod vs placebo at week 8 (mean [SD] 1.096 [2.346] vs 2.267 [5.660]) and at week 24 (0.193 [0.594] vs 3.153 [9.984]). Patients who relapsed had higher baseline pNfL and week 24 GdE lesion counts than nonrelapsers (median [Q1, Q3] pNfL pg/mL: 11.597 [8.107, 14.474] vs 10.939 [7.541, 15.123]; mean [SD] GdE lesion count: 0.333 [0.707] vs 0.176 [0.582]). pNfL decreased from baseline more at week 4 in patients without vs with on-study relapses (median [Q1, Q3] % change from baseline: -7.891 [-19.475, 12.030] vs 0.389 [-17.513, 31.415]). Week 12 and 24 pNfL were the best predictors of week 24 GdE lesion count. Week 12 GdE lesion count was the best predictor of week 24 pNfL.

Ozanimod 0.92 mg reduced pNfL from baseline and was associated with fewer GdE lesions than placebo in patients with RMS. pNfL at week 12 and week 24 predicted GdE lesion count at week 24; GdE lesion count at week 12 predicted pNfL at week 24.
