Abstract Details

Impact of ozanimod treatment on cortical grey matter volume: up to 5 years’ experience in phase 3 and extension trials
Multiple Sclerosis
P5 - Poster Session 5 (11:45 AM-12:45 PM)
12-005

To describe the magnitude and duration of cortical grey matter volume (CGMV) change associated with interferon and to assess the long-term impact of switching to ozanimod in relapsing multiple sclerosis (RMS).
Accelerated early CGMV loss has been reported among RMS patients treated with interferon. 
CGMV was quantified in phase 3 SUNBEAM (NCT02294058) and RADIANCE (NCT02047734) trials of ozanimod and an ongoing extension trial (DAYBREAK, NCT02576717). The 2 randomized, double-blind trials compared oral ozanimod 0.92 and 0.46 mg/day with intramuscular interferon 30 μg/week in adults with RMS. Completers were eligible for open-label ozanimod 0.92 mg/day in DAYBREAK. MRI was performed at months 6 (SUNBEAM), 12 (RADIANCE/SUNBEAM), and 24 (RADIANCE), then every 12 months (DAYBREAK). CGMV was analyzed through DAYBREAK month 36.
The rate of CGMV loss was significantly (nominal P<0.001) greater with interferon than ozanimod 0.92 mg during the double-blind studies: least square mean percentage change from baseline was -0.67% vs -0.02% respectively at month 6 and -1.04% vs -0.16% at month 12 in SUNBEAM, and -0.80% vs -0.13% at month 12 and -1.26% vs -0.53% at month 24 in RADIANCE. Switching from interferon to ozanimod reversed CGMV loss in the first year of the extension study, during which CGMV increased by 0.07% and 0.11% from DAYBREAK baseline among patients who entered from RADIANCE and SUNBEAM, respectively. Thereafter, annualized rates of CGMV loss in DAYBREAK were similar among participants who switched from interferon and those continuously treated with ozanimod. At months 24 and 36 of DAYBREAK, patients continuously treated with ozanimod lost less CGMV relative to RADIANCE/SUNBEAM baseline than did patients initially treated with interferon.

Switching from interferon to ozanimod contributed to reversal of CGMV loss. Earlier treatment with ozanimod led to less CGMV loss over 4?5 years supporting the benefit of early treatment with ozanimod.
