IntroductionPatients with relapsing MS (RMS) who show an increased rate of relapse or disability worsening can be described as showing high disease activity (HDA). Treatment with cladribine tablets (CT) in the CLARITY study, and with CT added to interferon-β in the ONWARD study demonstrated efficacy vs. placebo (PBO) across a range of patients with active MS. Combining double-blind data from these studies allows assessment of the efficacy of treatment with CT 3.5 mg/kg (CT3.5; cumulative dose). The objective of this post-hoc analysis is to compare the effects of CT3.5 vs. PBO on the proportion of patients achieving no evidence of disease activity (NEDA) status in HDA subgroups identified using two sets of criteria in a pooled cohort of patients from CLARITY and ONWARD.MethodsPatients from CLARITY and ONWARD were retrospectively stratified using 2 sets of HDA criteria based on relapse history, prior treatment, and MRI characteristics: high relapse activity (HRA; n=314) and HRA plus disease-activity-on-treatment (HRA +DAT; n=459). Patients treated with CT3.5 or PBO who fulfilled these criteria and achieved NEDA were compared over 2 years using odds ratios (ORs) and 95%CIs.ResultsIn the HRA subgroup, 76.5% of CT3.5-treated patients were relapse-free, 86.7% were T1 Gd +lesion free vs. 50.7% and 35.8%, respectively, for PBO. In the HRA +DAT subgroup, 77.6% were relapse-free and 88.8% were T1 Gd +lesion free with CT3.5 vs. 53.9% and 40.8%, respectively for PBO. In the HRA and HRA +DAT subgroups, 42.7% and 41.3%, respectively, of CT3.5-treated patients were disease activity free compared with 9.7%, (OR 6.94, 95% CI 3.67;13.12, p<0.0001) and 13.7% (OR 4.28, 95% CI 2.62;6.99, p<0.0001) respectively, of PBO recipients. In the overall CLARITY+ONWARD population (including non-HDA patients), the composite NEDA score also favoured CT over PBO (OR 3.95, 95% CI 2.90;5.37, p<0.0001).ConclusionCompared with placebo, treatment with CT3.5 was associated with increased odds of achieving NEDA in HDA patients.

Background: Daclizumab high-yield process (DAC HYP) is a humanized anti-CD25 monoclonal antibody that inhibits high-affinity interleukin-2 receptor signaling. Objective: The objective of this paper is to assess the proportion of DAC HYP- versus placebo-treated patients who were free from disease activity. Methods: SELECT was a randomized, double-blind, multicenter study of DAC HYP 150 mg or 300 mg, or placebo, administered subcutaneously every four weeks for 52 weeks. In this post-hoc analysis of the SELECT trial, ‘disease-activity free’ was defined as completion through week 52 without relapses or confirmed three-month disability progression (clinical), with no new/newly enlarging T2-hyperintense lesions and no new gadolinium-enhancing lesions at the week 52 scan (radiological). Primary analyses were based on logistic regression controlling for baseline characteristics. Results: More DAC HYP-treated (39%, n = 156) versus placebo-treated patients (11%, n = 22) were disease-activity free (odds ratio (95% confidence interval), 6.18 (3.71–10.32); p < 0.0001). Furthermore, 77% and 48% of DAC HYP-treated patients were free from clinical or radiological disease activity, respectively, compared with 60% and 18% of placebo-treated patients. Conclusion: At one year, DAC HYP resulted in a meaningful increase in the proportion of relapsing–remitting MS patients who were disease-activity free versus placebo.

Background and objective Several criteria for treatment response to interferon beta (IFNβ) have been proposed, although there is no consensus among different investigators. Hence, the aim of this study was to investigate magnetic resonance imaging (MRI) and clinical predictors of response during the first 12 months of therapy. Methods This is a prospective and longitudinal study of relapsing-remitting multiple sclerosis (RRMS) patients treated with IFNβ. Patients were classified based on the presence of new lesions on MRI, relapses, confirmed disability increase, or combinations of all these variables after 1 year of therapy. Regression analysis was performed in order to identify variables of response after a follow-up of 3 years. Results We included 222 RRMS patients. The logistic model demonstrated that only the combination of new active lesions on MRI with the presence of relapses (OR 4.4; 95% CI 1.6–12.5) or disability progression (Odds Ratio (OR) 7.1; 95% Confidence Interval (CI) 1.6–33.9), or both (OR 6.5; 95% CI 1.9–23.4) achieved significant values to identify those patients with a poor outcome. Conclusions In RRMS patients treated with IFNβ, the combination of measures of disease activity and the presence of new active lesions on MRI may have a prognostic value for identifying patients with disease activity in the second and third year of therapy.

Background: In the CLARITY (CLAdRIbine Tablets treating multiple sclerosis orallY) study, Cladribine Tablets significantly improved clinical and magnetic resonance imaging (MRI) outcomes (vs placebo) in patients with relapsing-remitting multiple sclerosis. Objective: Describe two clinically relevant definitions for patients with high disease activity (HDA) at baseline of the CLARITY study (utility verified in patients receiving placebo) and assess the treatment effects of Cladribine Tablets 3.5 mg/kg compared with the overall study population. Methods: Outcomes of patients randomised to Cladribine Tablets 3.5 mg/kg or placebo were analysed for subgroups using HDA definitions based on high relapse activity (HRA; patients with ⩾2 relapses during the year prior to study entry, whether on DMD treatment or not) or HRA plus disease activity on treatment (HRA + DAT; patients with ⩾2 relapses during the year prior to study entry, whether on DMD treatment or not, PLUS patients with ⩾1 relapse during the year prior to study entry while on therapy with other DMDs and ⩾1 T1 Gd+ or ⩾9 T2 lesions). Results: In the overall population, Cladribine Tablets 3.5 mg/kg reduced the risk of 6-month-confirmed Expanded Disability Status Scale (EDSS) worsening by 47% vs placebo. A risk reduction of 82% vs placebo was seen in both the HRA and HRA + DAT subgroups (vs 19% for non-HRA and 18% for non-HRA + DAT), indicating greater responsiveness to Cladribine Tablets 3.5 mg/kg in patients with HDA. There were consistent results for other efficacy endpoints. The safety profile in HDA patients was consistent with the overall CLARITY population. Conclusion: Patients with HDA showed clinical and MRI responses to Cladribine Tablets 3.5 mg/kg that were generally better than, or at least comparable with, the outcomes seen in the overall CLARITY population.

BackgroundSwitching between first-line disease-modifying therapies in patients with clinically stable relapsing–remitting multiple sclerosis (RRMS) due to reasons other than disease activity is frequent, but evidence on the effect of this practice is limited. We investigated the effect of switching patients with stable RRMS on occurrences of disability accumulation, relapses and future treatment discontinuation.MethodsUsing the Danish Multiple Sclerosis Registry, we identified patients with RRMS without disease activity who either (1) stayed on injectable platform therapy (interferon-β or glatiramer acetate) or (2) switched to dimethyl fumarate (DMF) or teriflunomide (TFL) and compared treatment outcomes using propensity-score-based methods and marginal structural models (MSM).ResultsWe included 3206 patients in the study. We found no change in risk of 6-month confirmed Expanded Disability Status Scale score worsening in patients switching to DMF (HR: 1.15, 95% CI 0.88 to 1.50) or TFL (HR: 1.16, 95% CI 0.92 to 1.46). The risk of suffering any relapse tended to decrease when switching to DMF (HR: 0.73, 95% CI 0.51 to 1.04) and tended to increase when switching to TFL (HR: 1.25, 95% CI 0.96 to 1.63). Absolute risk differences were small. MSM analyses showed similar results but did not find an increased relapse risk in TFL switchers.ConclusionSwitching from injectable platform therapies to oral first-line therapies in patients with clinically stable RRMS does not increase the risk of disability accumulation. While the postswitch risk of relapses trended towards marginally higher on TFL, this trend was eliminated by adjustment for time-variant confounders.

IntroductionTo compare effects of fingolimod vs. interferon beta-1a (IFN) in achieving no evidence of disease activity (NEDA-4) in patients with relapsing-remitting multiple sclerosis (RRMS) in the TRANSFORMS study. Adding Brain Volume Loss (BVL) to NEDA results in a more comprehensive and balanced measure of focal and diffuse damage.MethodsIn this post-hoc analysis, we used data from the fingolimod 0.5 mg daily (n=431) and IFN 30 µg weekly (n=435) groups. NEDA-4 was defined as absence of confirmed relapses, new/enlarging T2 lesions, 6-month confirmed disability progression (CDP) and BVL (annual percent brain volume change [PBVC] of >−0.4%). 3-month CDP and additional PBVC cut-offs representing mean BVL rates in healthy adults (0.2%), MS patients (0.6%), or accelerated BVL (1.2%) were also tested. Odds ratios (OR) were calculated for differences between fingolimod- and IFN-treated groups.ResultsSignificantly more fingolimod (n=425) than IFN-treated patients (n=418) achieved NEDA-4 status: 27.9% vs. 16.7% (OR:1.93; 95% CI: 1.36–2.73; p=0.0002). Results were similar for other PBVC cut-offs: (>–0.2%): 20.2% vs 11.5%; 1.94; 1.30–2.90, p=0.0011; (>–0.6%): 34.6% vs 20.4%; 2.06; 1.49–2.86, p<0.0001; (>–1.2%): 40.8% vs 26.4%; 1.92; 1.42–2.60; p<0.0001.ConclusionFingolimod-treated patients had twice the odds of achieving NEDA-4 status over 1 year as patients treated with IFN.
