ObjectiveMethodsNo evidence of progression or active disease (NEPAD) is a novel combined endpoint defined by the absence of both progression and inflammatory disease activity in primary progressive multiple sclerosis (PPMS). In the placebo-controlled phase III ORATORIO study (NCT01194570), we investigated the effect of ocrelizumab on this comprehensive outcome and its components in a post-hoc analysis. The proportion of patients with NEPAD (no evidence of progression [NEP; no 12-week confirmed progression of 1/0.5 points on the Expanded Disability Status Scale if the baseline score was 5.5/>5.5 points, respectively; no 12-week confirmed progression of 20% on the Timed 25-Foot Walk test and 9-Hole Peg Test], no brain magnetic resonance imaging activity [no new/enlarging T2 lesions and no T1 gadolinium-enhancing lesions], and no protocol-defined relapse) from baseline to week 120 was determined in ocrelizumab- (600mg; n=465) and placebo-treated (n=234) patients. ResultsInterpretationThe majority of ORATORIO study patients with PPMS experienced clinical progression or evidence of disease activity. From baseline to week 120, 29.9% and 42.7% ocrelizumab-treated compared to 9.4% and 29.1% placebo-treated patients maintained NEPAD (relative risk [95% confidence interval {CI}], 3.15 [2.07-4.79]; p<0.001) and NEP (relative risk [95% CI], 1.47 [1.17-1.84]; p<0.001), respectively. Effects on the individual components of both measures were consistent with the compound outcomes. Compared to placebo, ocrelizumab enhanced 3-fold the proportion of PPMS patients with no evidence of either progression or inflammatory disease activity. NEPAD may represent a sensitive and meaningful comprehensive measure of disease control in patients with PPMS. Ann Neurol 2018;84:527-536
