Treatment satisfaction, adherence and behavioral assessment in patients de-escalating from natalizumab to interferon ?.

ABSTRACT: De-escalating natalizumab (NTZ) to interferon beta 1b (IFN B 1B) is a possible treatment option in multiple sclerosis (MS) patients interrupting NTZ because of increased risk of progressive multifocal leukoencephalopathy (PML). The aim of this study was to evaluate satisfaction and adherence to treatment, behavioral and fatigue changes in patients switched to IFN B 1B compared to continued NTZ treatment.A 1 year, prospective, randomized, rater-blinded, parallel-group study. Nineteen relapsing remitting (RR) MS patients, randomly assigned to undergo either NTZ (n?=?10) or IFN B 1B (n?=?9) treatment, who had previously received NTZ for at least 12 months with disease stability and fearing or at risk for PML were included. Patients underwent behavioral and treatment assessments at baseline, after 24-week and 1 year follow-up. Behavioral assessment included measures of cognition, fatigue and quality of life. Treatment assessment included measures of satisfaction, persistence and adherence to treatment. Clinical-radiological disease activity and safety were also assessed.Baseline characteristics of patients were similar between groups except for Euro Quality Visual Analogue Scale, being higher in the NTZ group (p?=?0.04). Within-group comparisons at the three time points, as well as interaction analysis of treatment effect over time did not show any statistically significant differences in behavioral or treatment assessments, but a coherent trend favoring NTZ over IFN B 1B.De-escalating NTZ to IFN B 1B is feasible and associated with overall good patient related outcome and persistently stable behavioral measures.

Project description:IntroductionMultiple sclerosis (MS) typically requires life-long management with disease-modifying therapies (DMTs). Many DMTs require regular self-injection, and can be associated with injection site reactions, pain, and needle/injection phobia-but these can be addressed by improvements in autoinjector design. The aim of this study was to investigate patient satisfaction and preference for BETACONNECT™ (Bayer Pharma AG), a novel interferon beta-1b autoinjector.MethodsPatients in Germany performing self-injections using BETACONNECT took part in the study. Data were collected through an online 15-min structured survey. Participants rated their experience with BETACONNECT on a 6-point scale and those satisfied with BETACONNECT were asked to describe the reason using a free-text box.ResultsOne-hundred and eighteen patients with MS completed the survey. Ninety percent preferred BETACONNECT to their previous injection method (only 4% previously used manual injections, so most had previously used other autoinjectors). Ninety-two percent were very confident/confident in their ability to perform an injection using BETACONNECT. The most common free-text responses to "Why are you satisfied with the BETACONNECT™ autoinjector?" were ease of use (46%), less irritation/pain at the injection site (33%), and smoother injections (24%). Features considered most useful were automated injections (98%), adjustable injection speed (98%), and adjustable injection depth (98%). Ninety-seven percent thought it was easy to know when an injection was complete and 95% agreed/strongly agreed it was easy to learn to use the autoinjector. Seventy-three percent agreed that the quietness and effortlessness of the BETACONNECT reduced their level of injection anxiety, 92% that its size and shape makes it easy to handle during injections, and 67% that it decreases injection site pain. Eighty percent of those using the reminder function thought they were less likely to miss an injection.ConclusionPatients with MS self-injecting interferon beta-1b expressed a high level of satisfaction and preference for BETACONNECT. Thus, BETACONNECT represents a valid option to improve patients' overall injection experience.FundingBayer HealthCare Pharmaceuticals.

Project description:Introduction and backgroundAdherence is a critical factor for optimal clinical outcomes in multiple sclerosis (MS) treatment. This study investigated the adherence and clinical outcomes of MS patients treated with subcutaneous (sc) interferon (IFN) (β)-1a, an established immunomodulatory treatment for relapsing MS. The benefits of a patient support programme (PSP) were also studied.MethodsThis phase-IV prospective, observational multicentre study enrolled patients with relapsing MS who were treated with sc IFN β-1a for 24 months was conducted at 53 centres across 17 countries. The primary endpoint was adherence to sc IFN β-1a treatment, as assessed using Morisky Green Levine Medication Adherence Scale (MGLS) scores at 24 months. The MGLS is a self-reported diagnostic tool to address medication non-adherence, with a score ranging from 0 to 4, with 0 representing high adherence, 1-2 representing medium adherence, and 3-4 representing low adherence. Other endpoints included time to study and treatment discontinuation over 24 months, the proportion of relapse-free patients, and Expanded Disability Status Scale (EDSS) progression (defined as ≥1.0 point increase sustained for 3 months) at 24 months. A subgroup analysis was performed for endpoints based on patients assigned to PSP (yes/no-PSP versus non-PSP subgroup).ResultsOf the 577 patients enrolled, 408 had evaluable MGLS scores at 24 months. A total of 336 (58.2%; 95% confidence interval [CI]: 54.1-62.3%) patients reported high adherence, 57 (9.9%; 95% CIs: 7.6-12.7%) reported medium adherence, and 15 (2.6%; 95% CI: 1.5-4.3%) reported low adherence at 24 months. The PSP subgroup reported higher adherence (n = 206; 65.8%) than the non-PSP subgroup (n = 130; 56.5%). By 24 months, 52.2% of the patients were relapse-free and 17.2% patients experienced ≥1 relapse. Expanded Disability Status Scale progression was observed in 12.3% of patients. Over the 24-month period, 30.8% of the patients discontinued treatment, and the most common reasons for treatment discontinuation were adverse events (AEs, 10.4%), being lost to followup (7.1%), and a lack of efficacy (5.5%). Overall, 39.6% patients experienced ≥1 AE, which ranged from mild to moderate.ConclusionThe study demonstrated high adherence to sc IFN β-1a treatment with an added benefit of PSP participation. More than half of the patients remained relapse-free over a 24-month period. No new safety concerns to sc IFN β-1a treatment were observed.Clinical trial registrationhttps://clinicaltrials.gov/study/NCT02921035, NCT02921035.
