Background Ublituximab, a novel monoclonal antibody, targets a unique epitope of CD20 and is glycoengineered for enhanced antibody-dependent cellular cytotoxicity. Phase 3 ULTIMATE I and II studies showed significant improvements in relapse rate, number of gadolinium-enhancing (Gd+) T1 lesions, new/enlarging T2 lesions, and NEDA for ublituximab vs teriflunomide at 96 weeks.

Objective To characterize the effects of ublituximab on NEDA.

Design/Methods In ULTIMATE I (N=549) and II (N=545), patients with RMS received ublituximab 450 mg intravenous infusion every 24 weeks (following Day 1 infusion of 150 mg) or teriflunomide 14 mg oral once daily for 96 weeks. Post hoc pooled analyses evaluated NEDA by treatment epoch and patient subtype: treatment-naive (Tx-naive), prior disease-modifying therapy (Tx-exp), and ≤3 years (Early-dz) and >3 years (Late-dz) following diagnosis. NEDA was defined as no confirmed relapses, no T1 Gd+ lesions, no new/enlarging T2 lesions, and no 12-week confirmed disability progression.

Results

NEDA rates for ublituximab vs teriflunomide cohorts by treatment epoch (weeks) were 0-96: 44.6% vs 12.4% (3.6x improvement); 24-96 (re-baselined): 82.1% vs 22.5% (3.6x improvement); 0-24: 53.3% vs 29.2% (1.8x improvement); 0-48: 49.3% vs 20.1% (2.5x improvement); and 48-96 (re-baselined): 88.2% vs 30.4% (2.9x improvement) (P<0.0001 for all). NEDA at 24-96 weeks (re-baselined) was achieved in 82.7% and 23.1% (3.6x improvement) of Tx-naive, 81.1% and 21.1% (3.8x improvement) of Tx-exp, 82.4% and 18.6% (4.4x improvement) of Early-dz, and 81.9% and 26.5% (3.1x improvement) of Late-dz patients in ublituximab- vs teriflunomide-treated cohorts, respectively (P<0.0001 for all). Disease activity during Weeks 24-96 (entire population) was relapse (11.4% vs 22.9%), progression (4.9% vs 6.3%), Gd+ lesions (0.6% vs 40.9%), and/or new/enlarging T2 lesions (3.1% vs 71.6%) in ublituximab vs teriflunomide patients.

Conclusions ULTIMATE I and II post hoc pooled analyses demonstrated a consistent NEDA benefit for ublituximab-treated patients across treatment epochs and key patient subpopulations.
