Expert opinion on the use of contraception in people with multiple sclerosis.

BACKGROUND: Current guidance on the selection of appropriate contraception for people with multiple sclerosis (PwMS) is lacking. OBJECTIVE: To address this gap, an expert-led consensus program developed recommendations to support clinicians in discussing family planning and contraception with women and men with multiple sclerosis (MS). METHODS: A multidisciplinary steering committee (SC) of 13 international clinical experts led the program, supported by an extended faculty of 32 experts representing 18 countries. A modified Delphi methodology was used for decision-making and consensus-building. The SC drafted 15 clinical questions focused on patient-centered care, selection of contraception, and timing of stopping/starting contraception and disease-modifying therapies (DMTs). Statements addressing each question were drafted based on evaluation of published evidence and the experts' clinical experience. Consensus was reached if ⩾75% of respondents agreed (scoring 7-9 on a 9-point scale) with each recommendation. RESULTS: Consensus was reached on 24 of 25 proposed recommendations, including how and when to discuss contraception, types and safety of contraceptives, and how to evaluate the most appropriate contraceptive options for specific patient groups, including those with significant disability or being treated with DMTs. CONCLUSION: These expert recommendations provide the first practical, relevant, and comprehensive guidance for clinicians on the selection of contraception in PwMS.

Long-term follow-up of patients with relapsing multiple sclerosis from the CLARITY/CLARITY Extension cohort of CLASSIC-MS: An ambispective study.

BACKGROUND: CLASSIC-MS evaluated the long-term efficacy of cladribine tablets in patients with relapsing multiple sclerosis. OBJECTIVE: Report long-term mobility and disability beyond treatment courses received in CLARITY/CLARITY Extension. METHODS: This analysis represents CLASSIC-MS patients who participated in CLARITY with/without participation in CLARITY Extension, and received ⩾1 course of cladribine tablets or placebo (N = 435). Primary objective includes evaluation of long-term mobility (no wheelchair use in the 3 months prior to first visit in CLASSIC-MS and not bedridden at any time since last parent study dose (LPSD), i.e. Expanded Disability Status Scale (EDSS) score <7). Secondary objective includes long-term disability status (no use of an ambulatory device (EDSS < 6) at any time since LPSD). RESULTS: At CLASSIC-MS baseline, mean ± standard deviation EDSS score was 3.9 ± 2.1 and the median time since LPSD was 10.9 (range = 9.3-14.9) years. Cladribine tablets-exposed population: 90.6% (N = 394), including 160 patients who received a cumulative dose of 3.5 mg/kg over 2 years. Patients not using a wheelchair and not bedridden: exposed, 90.0%; unexposed, 77.8%. Patients with no use of an ambulatory device: exposed, 81.2%; unexposed, 75.6%. CONCLUSION: With a median 10.9 years' follow-up after CLARITY/CLARITY Extension, findings suggest the sustained long-term mobility and disability benefits of cladribine tablets.

A systematic review of relapse rates during pregnancy and postpartum in patients with relapsing multiple sclerosis.

INTRODUCTION: Pregnancy is widely accepted as a period when relapses of multiple sclerosis (MS) are decreased, with an increased risk of relapse in the first months postpartum. This systematic review evaluated relapses during pregnancy and postpartum, according to disease-modifying therapy (DMT) exposure before, during, and after pregnancy, and the influence of DMT on these outcomes. METHODS: We searched Medline and EMBASE to identify relevant publications from November 2009 to 2019 along with references lists of selected articles. Publications were filtered and assessed by two independent reviewers to ensure appropriate data extraction. RESULTS: Of 469 articles identified, 28 were included for analysis including 4739 pregnancies in 5324 patients. All five studies comparing natalizumab or fingolimod (high-efficacy DMTs) use preconception versus interferon beta, glatiramer acetate, or dimethyl fumarate, or no DMT suggested that there was a greater risk of relapse during pregnancy following withdrawal of the high-efficacy DMTs. Of 10 studies evaluating relapses during pregnancy, five studies found that continuing DMTs into early pregnancy reduced relapses compared to discontinuing treatment. DMT exposure preconception generally had no effect on postpartum relapses versus no DMT; however, natalizumab or fingolimod use preconception was associated with postpartum relapse versus no high-efficacy DMT in one study. DMT exposure during pregnancy was associated with fewer postpartum relapses versus no DMT exposure in four of seven studies, while three found no difference between groups. CONCLUSION: Results of this systematic review concerning women with relapsing MS show a complex and often conflicting picture regarding DMT exposure and relapses during and after pregnancy. Although our data are limited by variability between studies, there is some evidence suggesting the use of natalizumab or fingolimod preconception is associated with increased risk of relapses during pregnancy, highlighting the need for effective disease-management strategies in these especially high-risk patients.

Factors influencing long-term outcomes in relapsing-remitting multiple sclerosis: PRISMS-15.

AIM: An exploratory study of the relationship between cumulative exposure to subcutaneous (sc) interferon (IFN) ß-1a treatment and other possible prognostic factors with long-term clinical outcomes in relapsing-remitting multiple sclerosis (RRMS). METHODS: Patients in the original PRISMS study were invited to a single follow-up visit 15 years after initial randomisation (PRISMS-15). Outcomes over 15 years were compared in the lowest and highest quartile of the cumulative sc IFN ß-1a dose groups, and according to total time receiving sc IFN ß-1a as a continuous variable per 5 years of treatment. Potential prognostic factors for outcomes were analysed. RESULTS: Of 560 patients randomised in PRISMS, 291 returned for PRISMS-15 and 290 (51.8%) were analysed. Higher cumulative dose exposure and longer treatment time appeared to be associated with better outcomes on: annualised relapse rate, number of relapses, time to Expanded Disability Status Scale (EDSS) progression, change in EDSS, proportions of patients with EDSS ≥ 4 or ≥ 6, ≤ 5 relapses and EDSS <4 or <6, and time to conversion to secondary-progressive MS (SPMS). Higher dose exposure was associated with lower proportions of patients with EDSS progression and conversion to SPMS, and longer time on treatment with lower risk of first relapse. Change in EDSS from baseline to 24 months was a strong predictor of evaluated clinical outcomes over 15 years. CONCLUSIONS: These findings suggest that higher cumulative exposure to sc IFN ß-1a may be associated with better clinical outcomes, and early change in EDSS score may have prognostic value, over many years, in RRMS.

Autoinjector preference in multiple sclerosis and the role of nurses in treatment decisions: results from an international survey in Europe and the USA.

PURPOSE: This international survey recorded the opinions of multiple sclerosis (MS) nurses about their role in treatment decision making and about the importance of different attributes of autoinjectors used to deliver first-line parenteral therapy. METHODS: The survey involved 52 MS nurses in different practice settings in France, Germany, Italy, the UK, and the USA. Nurses described their role in patient education and in treatment decision making. They also rated the importance of nine prespecified attributes of autoinjectors and stated their preference, both overall and by attribute, for one of two autoinjectors used to deliver interferon ß-1b (ExtaviPro® 30G and Betacomfort®). Nurses' preferences were compared with those previously collected from patients using an identical questionnaire. RESULTS: There were pronounced differences between practice settings and between countries in the opinions of MS nurses about their influence on treatment decision making. Nurses considered themselves instrumental in helping patients decide between treatment options offered by neurologists. Of the nine autoinjector attributes, nurses rated "reliable to use" as most important, followed by attributes associated with convenience ("easy to operate," "ergonomic shape," "reach" [of injection sites], and "one-handed injection"). Nurses' and patients' rankings of attributes were closely aligned. For the nine attributes, 74%-98% of nurses preferred ExtaviPro® 30G to Betacomfort®, 94% preferring ExtaviPro® 30G overall. Nurses showed a greater preference than patients for ExtaviPro® 30G with respect to "easy to operate" (92% vs 78%), "intuitive to use" (98% vs 78%), and "attractive design" (98% vs 83%; P<0.05, all), but preference rates were otherwise similar across the two groups. The most common reasons in both groups for preferring ExtaviPro® 30G to Betacomfort® were "easy to use" and "ergonomic shape." CONCLUSION: MS nurses play a key role in patient guidance and education. Their preferences for ExtaviPro® 30G likely reflect their understanding of the challenges patients face when self-administering treatment.

Understanding and meeting injection device needs in multiple sclerosis: a survey of patient attitudes and practices.

BACKGROUND: All established disease-modifying drugs for multiple sclerosis require parenteral administration, which can cause difficulties for some patients, sometimes leading to suboptimal adherence. A new electronic autoinjection device has been designed to address these issues. METHODS: Patients with relapsing multiple sclerosis currently receiving subcutaneous or intramuscular interferon beta-1a, interferon beta-1b, or glatiramer acetate completed an online questionnaire (July 4-25, 2008) that surveyed current injection practices, experiences with current injection methods, and impressions and appeal of the new device. RESULTS: In total, 422 patients completed the survey, of whom 44% used autoinjectors, 43% prefilled syringes, and 13% syringes and vials; overall, 66% currently self-injected. Physical and psychological barriers to self-injection included difficulty with injections, needle phobia, and concerns over correct injection technique. Only 40% of respondents were "very satisfied" with their current injection method. The new electronic autoinjector was rated as "very appealing" by 65% of patients. The benefits of the new device included the ability to customize injection settings and to review dosing history. CONCLUSION: New technologies may help patients overcome physical and psychological barriers to self-injection. The combination of a reliable and flexible autoinjection device with dose-monitoring technology may improve communication between health care professionals and patients, and improve treatment adherence.

Review of subcutaneous interferon ß-1a, delivered via the electronic self-injection device RebiSmart™, for the treatment of multiple sclerosis.

Multiple sclerosis is a chronic disease requiring lifelong treatment with disease-modifying drugs that aim to prevent relapses and slow the progression of disability. The established first-line treatments for multiple sclerosis all require regular injections, and real-world observations suggest that long-term adherence to treatment is low. Indeed, poor adherence to disease-modifying drug treatment has been associated with poorer clinical outcomes. Autoinjectors have been developed to improve the success of self-injection, whilst also making injections more comfortable for patients, with the aim of minimizing obstacles to treatment adherence. RebiSmart™ is a new electronic autoinjector for subcutaneous administration of interferon ß-1a (Rebif®) that includes several unique features designed to further reduce barriers to adherence, including a dosing log and adjustable comfort settings.

Patient-rated suitability of a novel electronic device for self-injection of subcutaneous interferon beta-1a in relapsing multiple sclerosis: an international, single-arm, multicentre, Phase IIIb study.

BACKGROUND: Multiple sclerosis (MS) currently requires long-term treatment with disease-modifying drugs, administered parenterally up to once daily. The need for regular self-injection can be a barrier to treatment for many patients. Autoinjectors can help patients overcome problems or concerns with self-injection and could, therefore, improve treatment adherence. This study was performed to assess the suitability of a new electronic device for the subcutaneous (sc) administration of interferon (IFN) beta-1a, 44 mcg three times weekly, for relapsing MS. METHODS: In this Phase IIIb, multicentre, single-arm study, patients with relapsing MS who had been consistently self-injecting sc IFN beta-1a using an autoinjector for at least 6 weeks were taught to use the new device and self-administered treatment for 12 weeks thereafter. Patient-rated suitability of the device was assessed at the end of Week 12 using the Patient User Trial Questionnaire. Patient satisfaction with, and evaluation of, the injection process was assessed using the MS Treatment Concern Questionnaire. Trainers evaluated the device using the Trainer User Trial Questionnaire. RESULTS: At Week 12, 71.6% (73/102) of patients considered the device 'very suitable' or 'suitable' for self-injection; 92.2% (94/102) reported some degree of suitability and only 7.8% (8/102) found the device 'not at all suitable'. At Weeks 4, 8 and 12, most patients reported that injection preparation and clean-up, performing injections and ease of device use in the previous 4 weeks compared favourably with, or was equivalent to, their previous experience of self-injection. Injection-related pain, injection reactions and 'flu-like' symptoms remained stable over the 12 weeks. Each device feature was rated 'very useful' or 'useful' by at least 80% of patients. All trainers and 95.2% (99/104) of patients found device functions 'very easy' or 'easy' to use. Overall convenience was considered the most important benefit of the device. CONCLUSIONS: Most patients considered the new electronic injection device suitable for the sc injection of IFN beta-1a. They found the device easy to use with useful features, and reported benefits such as overall convenience. The device may, therefore, increase treatment adherence in patients with MS, particularly those with injection-related issues. TRIAL REGISTRATION: NCT00735007.
