Background: MS treatment goals are evolving with the emergence of higher-efficacy therapies. NEDA is a composite measure of the absence of clinical and MRI findings and a rapidly emerging treatment goal. Methods: In OPERA I and OPERA II, patients were randomized (1:1) to receive ocrelizumab 600mg via intravenous infusion every 24 weeks or subcutaneous IFNβ-1a 44μg three-times weekly over 96 weeks. NEDA (defined as no relapses, confirmed disability progression [CDP], new/enlarging T2 lesions, or gadolinium-enhancing T1 lesions) was analyzed over 96 weeks. MRI was assessed at baseline, 24, 48, and 96 weeks. Results: At 96 weeks, 47.9[percnt] and 47.5[percnt] of ocrelizumab-treated patients vs 29.2[percnt] and 25.1[percnt] of IFNβ-1a-treated patients achieved NEDA in OPERA I (64[percnt] increase; p<0.0001) and OPERA II (89[percnt] increase; p<0.001), respectively: 80.4[percnt] and 78.9[percnt] of ocrelizumab-treated patients vs 66.7[percnt] and 64.5[percnt] of IFNβ-1a-treated were without relapses; 92.4[percnt] and 89.4[percnt] of ocrelizumab-treated patients vs 87.8[percnt] and 84.9[percnt] of IFNβ-1a-treated were without CDP; 91.7[percnt] and 90.2[percnt] of ocrelizumab-treated patients vs 69.8[percnt] and 63.9[percnt] of IFNβ-1a-treated were without gadolinium-enhancing T1 lesions; and 61.7[percnt] and 60.9[percnt] of ocrelizumab-treated patients vs 38.7[percnt] and 38.0[percnt] of IFNβ-1a-treated were without new/enlarging T2 lesions in OPERA I and OPERA II, respectively. After week 24, ≥96.0[percnt] of all ocrelizumab-treated patients compared with 60.8-70.9[percnt] of IFNβ1-a-treated patients were without new/enlarging T2 lesions. Conclusions: Ocrelizumab consistently resulted in greater achievement of NEDA vs IFNβ-1a over 96 weeks, with elimination of new/enlarging T2 lesions in nearly all patients after week 24.
