Our study of PwMS and HCPs in the MS in the 21st Century initiative has highlighted eight practical actions. These actions identify how differences and gaps in unmet needs, treatment burden, and patient engagement between PwMS and HCPs can be bridged to improve MS disease management. Of particular interest now are patient-centred educational resources that can be used during time-limited consultations to enhance understanding of disease and improve communication. Actively bridging these gaps in a joint approach enables PwMS to take part in shared decision-making; with improved communication and reliable information, patients can make informed decisions with their HCPs, as part of their own personalised disease management.

Trials of anti-inflammatory therapies in non-relapsing progressive multiple sclerosis (MS) have been stubbornly negative except recently for an anti-CD20 therapy in primary progressive MS and a S1P modulator siponimod in secondary progressive MS. We argue that this might be because trials have been too short and have focused on assessing neuronal pathways, with insufficient reserve capacity, as the core component of the primary outcome. Delayed neuroaxonal degeneration primed by prior inflammation is not expected to respond to disease-modifying therapies targeting MS-specific mechanisms. However, anti-inflammatory therapies may modify these damaged pathways, but with a therapeutic lag that may take years to manifest. Based on these observations we propose that clinically apparent neurodegenerative components of progressive MS may occur in a length-dependent manner and asynchronously. If this hypothesis is confirmed it may have major implications for the future design of progressive MS trials.

IntroductionRare cases of thrombotic microangiopathy (TMA), manifested as thrombotic thrombocytopenic purpura (TTP) or hemolytic uremic syndrome (HUS), have been reported with interferon β products. We performed a cumulative review of TMA cases recorded in a Global Safety Database for patients with multiple sclerosis who received subcutaneous interferon β-1a treatment.MethodsSearch criteria were: all reported cases, serious and non-serious, from all sources (including non-health care professionals and clinical trial reports), regardless of event ranking and causality assessment by reporter or company. Data lock was May 3, 2014, with additional analysis of cases reported between August 1, 2014–November 30, 2014.ResultsNinety-one patient cases (76.9% female) with 105 events were retrieved. Time to onset varied from 2 months to 14 years, and in 31.9% of patients the event occurred within 2 years of treatment initiation. Seven patients had a fatal outcome (five were secondary to other causes and two reported insufficient information). Forty-four patients recovered, 32 patients had not recovered at the time of the report, and in eight cases outcome was either not reported or unknown. Treatment was discontinued in 84.6% (77/91) of patients. In 67% (61/91) of patients, the reporter suspected a causal association between treatment and TMA/TTP-HUS. Risk factors and/or confounding factors were present in 45.1% (41/91) of patients. Early prodromal syndrome or specific patterns were not detected, although 54.9% (50/91) of cases contained insufficient information. Overall reporting rate of TMA/TTP-HUS was estimated as 7.2 per 100,000 patient-years. Reporting rates for human serum album (HSA)-containing and HSA-free formulations were 5.72 and 7.68 per 100,000 patient-years, respectively.ConclusionNo new signal relating specifically to increased frequency of TMA/TTP-HUS with HSA-free subcutaneous interferon β-1a was detected and no additional risk mitigation measures are required regarding the different formulations. The benefit–risk balance of subcutaneous interferon β-1a remains positive, and routine pharmacovigilance monitoring is appropriate.FundingAres Trading SA, Aubonne, Switzerland, a subsidiary of Merck Serono SA.Electronic supplementary materialThe online version of this article (doi:10.1007/s12325-015-0212-6) contains supplementary material, which is available to authorized users.

Multiple sclerosis (MS) is among the most common autoimmune disabling neurological conditions of young adults and affects more than 2.3 million people worldwide. Predicting future disease activity in patients with MS based on their pathophysiology and current treatment is pivotal to orientate future treatment. In this respect, we used machine learning to predict disease activity status in patients with MS and identify the most predictive covariates of this activity. The analysis is conducted on a pooled population of 1935 patients enrolled in three cladribine tablets clinical trials with different outcomes: relapsing–remitting MS (from CLARITY and CLARITY‐Extension trials) and patients experiencing a first demyelinating event (from the ORACLE‐MS trial). We applied gradient‐boosting (from XgBoost library) and Shapley Additive Explanations (SHAP) methods to identify patients' covariates that predict disease activity 3 and 6 months before their clinical observation, including patient baseline characteristics, longitudinal magnetic resonance imaging readouts, and neurological and laboratory measures. The most predictive covariates for early identification of disease activity in patients were found to be treatment duration, higher number of new combined unique active lesion count, higher number of new T1 hypointense black holes, and higher age‐related MS severity score. The outcome of this analysis improves our understanding of the mechanism of onset of disease activity in patients with MS by allowing their early identification in clinical settings and prompting preventive measures, therapeutic interventions, or more frequent patient monitoring.

Cladribine tablets (CladT) is a highly active oral disease-modifying therapy (DMT) for the management of relapsing multiple sclerosis (RMS). CladT acts as an immune reconstitution ther-
