Project description:BACKGROUND:Fingolimod is a once-daily, orally administered therapy for relapsing forms of MS. It has been shown to reduce relapse rates significantly in all phase II and phase III clinical trials when compared with placebo and intramuscular interferon ?-1a (IFN?-1a IM). METHODS:This study compared annualized relapse rates (ARRs) associated with fingolimod, placebo and IFN?-1a IM, in patient subgroups from the pooled FREEDOMS, FREEDOMS II, and TRANSFORMS populations. This provided a large data set in which the efficacy of fingolimod could be assessed across a range of patient subgroups, including clinically relevant subgroups not previously analysed. RESULTS:Compared with placebo, fingolimod was associated with significantly lower ARRs across all patient subgroups with relative reductions in ARRs ranging from 35% (patients who had previously received treatment for their MS for up to 1 year; P<0.05) to 69% (patients with symptoms for less than 3 years before study entry; P<0.001). Other relative reductions in ARR compared with placebo included 64% in patients aged 40 years or younger and 63% in those naïve to treatment (P<0.001 for both). Compared with IFN?-1a IM, the greatest benefits to ARR were seen in patients aged 40 years or younger (55% relative ARR reduction, P<0.001) and in a small subgroup of patients who had previously received IFN? and glatiramer acetate (55% relative ARR reduction; P<0.05). Reductions in ARR compared with IFN?-1a IM were not statistically significant in men (33%, P=0.081), in patients aged over 40 years (23%, P=0.230) and in those who had received treatment prior to the study for 1 year or less (35%, P=0.108). Fingolimod was associated with significantly lower ARRs compared with placebo and with IFN?-1a IM irrespective of treatment status (treatment-naïve and previously treated for MS), and regardless of type of previous therapy. CONCLUSIONS:Fingolimod provided consistent efficacy benefits over placebo and IFN?-1a IM across a range of subgroups of patients with relapsing MS. The magnitude of the beneficial effect of fingolimod over IFN?-1a IM may depend on age, sex, and duration of previous treatment. These findings suggest that most benefit will be gained by patients who start fingolimod early in the disease course, but the findings also suggest that fingolimod treatment will benefit patients later in the disease course when they have already accrued disability.

Project description:Background and objectivesTo investigate the potential of plasma neurofilament light (pNfL) as a biomarker of disease progression and treatment response in progressive multiple sclerosis (PMS) with and without acute disease activity.MethodsA post hoc blinded analysis of pNfL levels in 2 placebo-controlled, phase 3 studies in secondary progressive multiple sclerosis (SPMS; EXPAND) and primary progressive multiple sclerosis (PPMS; INFORMS) using siponimod and fingolimod, respectively, as active compounds was performed. pNfL levels were quantified using a single molecule array (Homebrew Simoa) immunoassay from stored ethylenediaminetetraacetic acid (EDTA) plasma samples of all patients who consented for exploratory biomarker analysis in either study; pNfL levels were divided into high (≥30 pg/mL) and low (<30 pg/mL) at baseline. We investigated the association of pNfL levels with disability progression, cognitive decline, and brain atrophy and their sensitivity to indicate treatment response through clinical measures.ResultsWe analyzed pNfL in 4,185 samples from 1,452 patients with SPMS and 1,172 samples from 378 patients with PPMS. Baseline pNfL levels were higher in SPMS (geomean 32.1 pg/mL) than in PPMS (22.0 pg/mL; p < 0.0001). In both studies, higher baseline pNfL levels were associated with older age, higher Expanded Disability Status Scale score, more Gd+ lesions, and higher T2 lesion load (all p < 0.05). Independent of treatment, high vs low baseline pNfL levels were associated with significantly higher risks of confirmed 3-month (SPMS [32%], hazard ratio [95% CI] 1.32 [1.09-1.61]; PPMS [49%], 1.49 [1.05-2.12]) and 6-month disability progression (SPMS [26%], 1.26 [1.01-1.57]; PPMS [48%], 1.48 [1.01-2.17]), earlier wheelchair dependence (SPMS [50%], 1.50 [0.96-2.34]; PPMS [197%], 2.97 [1.44-6.10]), cognitive decline (SPMS [41%], 1.41 [1.09-1.84]), and higher rates of brain atrophy (mean change at month 24: SPMS, -0.92; PPMS, -1.39). Baseline pNfL levels were associated with future disability progression and the degree of brain atrophy regardless of presence or absence of acute disease activity (gadolinium-enhancing lesions or recent occurrence of relapses before baseline). pNfL levels were lower in patients treated with siponimod or fingolimod vs placebo-treated patients and higher in those having experienced disability progression.DiscussionpNfL was associated with future clinical and radiologic disability progression features at the group level. pNfL was reduced by treatment and may be a meaningful outcome measure in PMS studies.Trial registration informationEXPAND (ClinicalTrials.gov identifier: NCT01665144) and INFORMS (ClinicalTrials.gov identifier: NCT00731692).

Project description:BackgroundFingolimod efficiently reduces multiple sclerosis (MS) relapse by inhibiting lymphocyte egress from lymph nodes through down-modulation of sphingosine 1-phosphate (S1P) receptors. We aimed to clarify the alterations in peripheral blood T cell subsets associated with MS relapse on fingolimod.Methods/principal findingsBlood samples successively collected from 23 relapsing-remitting MS patients before and during fingolimod therapy (0.5 mg/day) for 12 months and 18 healthy controls (HCs) were analysed for T cell subsets by flow cytometry. In MS patients, the percentages of central memory T (CCR7+CD45RO+) cells (TCM) and naïve T (CCR7+CD45RO-) cells decreased significantly, while those of effector memory T (CCR7-CD45RA-) and suppressor precursor T (CD28-) cells increased in both CD4+T and CD8+T cells from 2 weeks to 12 months during fingolimod therapy. The percentages of regulatory T (CD4+CD25highCD127low) cells in CD4+T cells and CCR7-CD45RA+T cells in CD8+T cells also increased significantly. Eight relapsed patients demonstrated greater percentages of CD4+TCM than 15 non-relapsed patients at 3 and 6 months (p=0.0051 and p=0.0088, respectively). The IL17-, IL9-, and IL4-producing CD4+T cell percentages were significantly higher at pre-treatment in MS patients compared with HCs (p<0.01 for all), while the IL17-producing CD4+T cell percentages tended to show a transient increase at 2 weeks of fingolimod therapy (pcorr=0.0834).ConclusionsThe CD4+TCM percentages at 2 weeks to 12 months during fingolimod therapy are related to relapse.

Project description:To determine whether basing the decision to initiate immediate vs delayed disease-modifying therapy (DMT) on extent of recovery after initial relapse affects long-term disability accumulation in a multiple sclerosis (MS) evidence-based setting. We analyzed the double-blind, placebo-controlled interferon beta-1a 30 mc once a week in clinically isolated syndrome and 10-year-follow-up extension trial. Good recovery after presenting relapse was defined as (1) full early recovery within 28 days of symptom onset (Expanded Disability Status Scale [EDSS] score of 0 at enrollment maintained ≥6 months) and (2) delayed good recovery (EDSS score > 0 at enrollment and improvement from peak deficit to 6th-month or 1-year visit ≥ median). Time from recovery assignment to future disability (EDSS score ≥ 2.5 or ≥4.0) was studied on a relapse-recovery-stratified age axis and immediate vs 3-year delayed treatment initiation with Kaplan-Meier statistics and hazard ratios (HRs). One hundred seventy-five/328 patients had good recovery (94 immediate and 81 delayed treatment); 153 did not have good recovery (77 immediate and 76 delayed treatment). HRs for EDSS score ≥2.5 outcome were: delayed treatment without good recovery as reference (HR = 1.0), delayed treatment with good recovery (HR6th-month: 0.67, p = 0.207; HR1st-year: 0.40, p = 0.027), immediate treatment without good recovery (HR6th-month: 0.56, p = 0.061; HR1st-year: 0.40, p = 0.011), and immediate treatment with good recovery (HR6th-month: 0.43, p = 0.014; HR1st-year: 0.48, p = 0.034). Placebo patients were switched to long-term treatment after 3 years, and insufficient EDSS score ≥4.0 outcome events were available to study. In patients with MS presenting without good recovery after the initial relapse, immediate DMT initiation favorably influences the likelihood of more ambulatory-benign disease akin to patients with good recovery after the initial relapse. This study provides Class III evidence that for patients with MS without good recovery after the initial relapse, immediate DMT initiation increases the likelihood of a benign disease course.

Project description:To minimize the clinical burden associated with multiple sclerosis (MS), early control of focal and diffuse CNS disease activity is a treatment priority. A post hoc analysis was conducted to evaluate the onset of efficacy of fingolimod treatment in patients with relapsing MS. Data from patients who received fingolimod 0.5 mg or placebo during either of two 24-month, double-blind, randomized, parallel-group clinical trials (FREEDOMS and FREEDOMS II) were pooled for analysis. Efficacy outcomes were: time to first confirmed relapse; annualized relapse rate (ARR); proportions of patients free from T1 gadolinium-enhancing lesions or new/newly enlarged T2 lesions; percentage brain volume loss (BVL); and change in Multiple Sclerosis Functional Composite (MSFC) z-score from baseline to 6 months. An early benefit was seen with fingolimod (N = 783) vs. placebo (N = 773) for ARR at both 3 and 6 months (3 months, 0.32 vs. 0.52, p = 0.0015; 6 months, 0.21 vs. 0.45, p < 0.0001). Time to first relapse was also delayed with fingolimod vs. placebo from day 48 onwards. At 6 months, more patients in the fingolimod group than in the placebo group were free from new MRI activity (65.3 vs. 40.5%, p < 0.0001) and had less BVL (37.1% reduction vs. placebo, p < 0.001). MSFC z-score favored fingolimod over placebo at 6 months, with improvements noted in 9-Hole Peg Test and Paced Auditory Serial Addition Test scores. Improvements in outcomes related to relapses, MRI, disability, cognition, and BVL occurred within 6 months of treatment initiation with fingolimod.

Project description:PurposeAsthma is a common comorbidity in patients with bronchiectasis and has been shown to increase the risk of bronchiectasis exacerbations. This paper explores the impact of comorbid asthma on patients receiving intravenous antibiotic treatment for bronchiectasis exacerbations.MethodsThis was a post hoc analysis of the Meropenem randomised controlled trial of 90 patients that had intravenous antibiotic treatment for bronchiectasis exacerbations. The participants were split into two groups: group 1 (asthma and bronchiectasis) and group 2 (bronchiectasis). The authors assessed response to treatment and time to next exacerbation.ResultsThere were 38 participants in group 1 and 34 participants in group 2. The groups were found to be comparable in terms of age, sex, and bronchiectasis severity (median (95% CI) group 1 and then group 2 data): age 64.0(59.3, 68.6) and 63.6(57.9, 69.4) years old, p = 0.8; 57.9% and 64.7% female, p = 0.6; Bronchiectasis Severity Index 11.1(9.8, 12.4) and 10.1(8.2, 12.0), p = 0.3. There was a similar response to treatment between the groups, but group 1 were found to relapse early by day 14, 31.6% in group 1 and 11.8% in group 2, p = 0.03. In the Cox proportional hazards model, asthma was the only independent risk factor for early relapse by day 14 (odds ratio (95% CI) 3.16 (1.02-9.79), p = 0.047).ConclusionThe clinical response to treatment was similar but patients with coexisting asthma were at increased risk of early relapse within 14 days of stopping intravenous antibiotic therapy.Clinical trial registrationNCT02047773.

Project description:BACKGROUND: Approximately one-third of patients with multiple sclerosis (MS) are unresponsive to, or intolerant of, interferon (IFN) therapy, prompting a switch to other disease-modifying therapies. Clinical outcomes of switching therapy are unknown. This retrospective study assessed differences in relapse rates among patients with MS switching from IFN to fingolimod or glatiramer acetate (GA) in a real-world setting. METHODS: US administrative claims data from the PharMetrics Plus™ database were used to identify patients with MS who switched from IFN to fingolimod or GA between October 1, 2010 and March 31, 2012. Patients were matched 1?1 using propensity scores within strata (number of pre-index relapses) on demographic (e.g. age and gender) and disease (e.g. timing of pre-index relapse, comorbidities and symptoms) characteristics. A claims-based algorithm was used to identify relapses while patients were persistent with therapy over 360 days post-switch. Differences in both the probability of experiencing a relapse and the annualized relapse rate (ARR) while persistent with therapy were assessed. RESULTS: The matched sample population contained 264 patients (n?=?132 in each cohort). Before switching, 33.3% of patients in both cohorts had experienced at least one relapse. During the post-index persistence period, the proportion of patients with at least one relapse was lower in the fingolimod cohort (12.9%) than in the GA cohort (25.0%), and ARRs were lower with fingolimod (0.19) than with GA (0.51). Patients treated with fingolimod had a 59% lower probability of relapse (odds ratio, 0.41; 95% confidence interval [CI], 0.21-0.80; p?=?0.0091) and 62% fewer relapses per year (rate ratio, 0.38; 95% CI, 0.21-0.68; p?=?0.0013) compared with those treated with GA. CONCLUSIONS: In a real-world setting, patients with MS who switched from IFNs to fingolimod were significantly less likely to experience relapses than those who switched to GA.

Project description:BackgroundA study was undertaken to evaluate remote monitoring via smartphone sensor-based tests in people with multiple sclerosis (PwMS). This analysis aimed to explore regional neural correlates of digital measures derived from these tests.MethodsIn a 24-week, non-randomized, interventional, feasibility study (NCT02952911), sensor-based tests on the Floodlight Proof-of-Concept app were used to assess cognition (smartphone-based electronic Symbol Digit Modalities Test), upper extremity function (Draw a Shape Test, Pinching Test), and gait and balance (Static Balance Test, Two-Minute Walk Test, U-Turn Test). In this post-hoc analysis, digital measures and standard clinical measures (e.g., Nine-Hole Peg Test [9HPT]) were correlated against regional structural magnetic resonance imaging outcomes. Seventy-six PwMS aged 18-55 years with an Expanded Disability Status Scale score of 0.0-5.5 were enrolled from two different sites (USA and Spain). Sixty-two PwMS were included in this analysis.ResultsWorse performance on digital and clinical measures was associated with smaller regional brain volumes and larger ventricular volumes. Whereas digital and clinical measures had many neural correlates in common (e.g., putamen, globus pallidus, caudate nucleus, lateral occipital cortex), some were observed only for digital measures. For example, Draw a Shape Test and Pinching Test measures, but not 9HPT score, correlated with volume of the hippocampus (r = 0.37 [drawing accuracy over time on the Draw a Shape Test]/ - 0.45 [touching asynchrony on the Pinching Test]), thalamus (r = 0.38/ - 0.41), and pons (r = 0.35/ - 0.35).ConclusionsMultiple neural correlates were identified for the digital measures in a cohort of people with early MS. Digital measures showed associations with brain regions that clinical measures were unable to demonstrate, thus providing potential novel information on functional ability compared with standard clinical assessments.

Project description:BackgroundThe Evaluate Patient OutComes (EPOC) study assessed physician- and patient-reported outcomes in individuals with relapsing multiple sclerosis who switched directly from injectable disease-modifying therapy (iDMT; glatiramer acetate, intramuscular or subcutaneous interferon beta-1a, or interferon beta-1b) to once-daily, oral fingolimod. Post hoc analyses evaluated the impact of a switch to fingolimod versus staying on each of the four individual iDMTs.MethodsOverall, 1053 patients were randomized 3:1 to switch to fingolimod or remain on iDMT. The primary endpoint was the change in Treatment Satisfaction Questionnaire for Medication (TSQM) Global Satisfaction score. Secondary endpoints included changes in scores for TSQM Effectiveness, Side Effects and Convenience subscales, Beck Depression Inventory-II (BDI-II), Fatigue Severity Scale (FSS), Patient-Reported Outcome Indices for Multiple Sclerosis (PRIMUS) Activities, 36-item Short-Form Health Survey (SF-36) Mental Component Summary (MCS) and Physical Component Summary (PCS) and mean investigator-reported Clinical Global Impressions of Improvement (CGI-I). All outcomes were evaluated after 6 months of treatment.ResultsChanges in TSQM Global Satisfaction scores were superior after a switch to fingolimod when compared with scores in patients remaining on any of the iDMTs (all p <0.001). Likewise, all TSQM subscale scores improved following a switch to fingolimod (all p <0.001), except when compared with glatiramer acetate for the TSQM Side Effects subscale (p = 0.111). FSS scores were found to be superior for fingolimod versus remaining on subcutaneous interferon beta-1a and interferon beta-1b, BDI-II scores were significantly improved for fingolimod except for the comparison with intramuscular interferon beta-1a, and SF-36 scores were superior with fingolimod compared with remaining on interferon beta-1b (MCS and PCS; p = 0.030 and p = 0.022, respectively) and subcutaneous interferon beta-1a (PCS only; p = 0.024). Mean CGI-I scores were superior with fingolimod when compared with continuing treatment with any of the iDMTs (all p <0.001).ConclusionsAfter 6 months, a switch to fingolimod showed superiority compared with remaining on each iDMT for a range of patient- and physician-reported outcomes, including global satisfaction with treatment.Trial registrationClinicalTrials.gov NCT01216072 .
