OBJECTIVE: Peginterferon β-1a (PEG-IFN-β-1a) is the most recent interferon beta formulation approved for treating relapsing-remitting multiple sclerosis (RRMS). We aim to describe the real-world utilization of PEG-IFN-β-1a in RRMS and compare it with other injectable disease-modifying therapies (DMTs). PATIENTS AND METHODS: In this population-based study, we used 2015-2019 routinely collected healthcare data of the Campania region of Italy from National Healthcare System DMT prescriptions, inpatient and outpatient clinical records of hospitals in Campania, and the Federico II University MS clinical registry for a subset of patients...

BACKGROUND: Based on data from two large cohort studies, a label update became applicable for the class of interferon beta therapies in 9/2019, allowing interferons during pregnancy and breastfeeding. OBJECTIVE: To assess pregnancy outcomes of women with multiple sclerosis (MS) exposed to peginterferon beta-1a or intramuscular interferon beta-1a therapy (IFN). DESIGN: Non-interventional post-authorization safety study. METHODS: PRIMA was conducted from April to October 2021 in Germany...

BACKGROUND: Accumulating evidence indicates that an early, robust type 1 interferon (IFN) response to SARS-CoV-2 is important in determining COVID-19 outcomes, with an inadequate IFN response associated with disease severity. Our objective was to examine the prophylactic potential of IFN administration to limit viral transmission. METHODS: A cluster randomised open label clinical trial was undertaken to determine the effects of pegylated IFNβ-1a administration on SARS-CoV-2 household transmission between December 3rd, 2020 and June 29th, 2021...

BACKGROUND: Interferon beta therapies are well-established disease-modifying treatments for patients with relapsing multiple sclerosis (MS). Based on clinical evidence from two large cohort studies, both, the EMA and FDA updated the labels of the interferon beta class in terms of pregnancy and breastfeeding in 2019 and 2020, respectively. To complement pregnancy label updates with patient-reported real-world data, this study examined German pregnancy and outcome reports including available data on child development from women with MS treated with peginterferon beta-1a or intramuscular (IM) interferon beta-1a...

OBJECTIVE: Multiple sclerosis (MS) is a multifactorial disease with increasingly complicated management. Our objective is to use on-demand computational power to address the challenges of dynamically managing MS. METHODS: A phase 3 clinical trial data (NCT00906399) were used to contextualize the medication efficacy of peg-interferon beta-1a vs placebo on patients with relapsing-remitting MS (RRMS). Using a set of reference patients (PORs), selected based on adequate features similar to those of an individual patient, we visualize disease activity by measuring the percentage of relapses, accumulation of new T2 lesions on MRI, and worsening EDSS during the clinical trial...

INTRODUCTION: Results from several clinical trials suggest there is a dose-response effect for beta interferon-1a (INFβ1a) in multiple sclerosis (MS). METHODS: Our objective was to confirm these results through a retrospective analysis of patients with MS who had breakthrough disease (BD) on intramuscular (IM) INFβ1a (Avonex®) once per week (QW), who were switched to twice per week (BIW) IM INFβ1a between 1995 and 2015. The primary outcome measure was no further BD for at least 24 months...

INTRODUCTION: Disease-modifying therapies (DMTs) are the mainstay of treatment for relapsing-remitting multiple sclerosis (RRMS). There is established evidence that DMTs are effective at reducing relapse rate and disease progression in RRMS, but there has been less consideration to the synthesis of MRI and neurocognitive outcomes, which play an increasingly important role in treatment decisions. The aim of this systematic review and network meta-analysis is to examine the relative efficacy, acceptability and tolerability of DMTs for RRMS, using MRI and neurocognitive outcomes...

Purpose: The purpose of this study was to assess the prevalence of injection site reactions (ISR) and flu-like symptoms (FLS) during treatment with subcutaneous (SC) interferon (IFN) beta therapies and to document measures to mitigate and prevent ISR and FLS. Patients and Methods: The cross-sectional post-authorization safety study PERFECT was conducted from 11/2017 to 7/2019 in neurology practices in Germany. Adult patients with relapsing-remitting multiple sclerosis (MS) receiving SC IFN beta for ≥3 months were eligible...

Subcutaneous (SC) interferons beta (IFN-beta) are effective therapies for the treatment of relapsing-remitting multiple sclerosis (RRMS). Factors such as dosing schedule, needle intolerance/fatigue, and side effects may impact patient satisfaction with treatment. Improvement of patient satisfaction may increase the adherence to treatment and the patient quality of life. This study was aimed at evaluating the impact of switching to "Peginterferon beta-1a (Peg-IFN beta-1a)" in patients with RRMS unsatisfied with other SC interferons...

BACKGROUND: Multiple disease-modifying therapies (DMTs) have been approved by the U.S. Food & Drug Administration for the treatment of relapsing-remitting multiple sclerosis (RRMS). In separately conducted clinical trials, peginterferon beta-1a, subcutaneous interferon beta-1a (SC IFN beta-1a), glatiramer acetate (GA), and teriflunomide have demonstrated efficacy for reducing relapses. No head-to-head phase III clinical trials have directly compared the treatment efficacy of peginterferon beta-1a with these other DMTs...

Background: Peginterferon beta-1a was developed for treatment of relapsing-remitting multiple sclerosis (RRMS) to provide an interferon with increased exposure to facilitate adherence by reducing frequency of application. This non-interventional observational study investigated the adherence to peginterferon beta-1a in real-world clinical practice settings. Methods: This prospective study was conducted from 1/2015 to 1/2018 at 77 German MS sites. Adult patients with RRMS (previously treated or treatment-naïve) receiving peginterferon beta-1a (125 µg SC every 2 weeks) were eligible for participation...

INTRODUCTION: Injection site reactions (ISRs) and flu-like symptoms (FLS) are common in patients with relapsing forms of multiple sclerosis (MS) treated with peginterferon beta-1a. The purpose of this Delphi analysis was to explore peginterferon beta-1a discontinuation rates across MS treatment centers, to obtain consensus on effective mitigation and management strategies for ISRs and FLS, and to identify areas where additional training and education for nurses and patients could improve treatment outcomes...

BACKGROUND: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) target immunity and have the potential to increase the risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and alter its clinical course. We assessed these risks in patients with MS (PwMS). OBJECTIVE: The objective of this study was to describe the overall risk of coronavirus disease 2019 (COVID-19) infection, severe disease course, and potential population-level predictors of COVID-19 infection in PwMS, and to provide a context using a cohort of patients with systemic lupus erythematosus (SLE)...

Background: Peginterferon beta-1a administered every 2 weeks via subcutaneous (SC) injection is approved to treat adult patients with relapsing-remitting multiple sclerosis (RRMS) and relapsing forms of multiple sclerosis (RMS). However, associated injection site reactions (ISRs) can lead to treatment discontinuation. Prior studies with interferon beta-1a reported a lower frequency of ISRs with intramuscular (IM) administration than with SC administration. IM administration of peginterferon beta-1a may therefore represent a useful alternative treatment option...

Background: Peginterferon beta-1a and glatiramer acetate (GA) are approved first-line therapies for the treatment of relapsing forms of multiple sclerosis, but their therapeutic efficacy has not been compared directly. Methods: Clinical outcomes at 2 years, including no evidence of disease activity (NEDA), for patients receiving peginterferon beta-1a 125 mcg every 2 weeks (Q2W) or GA 20 mg/ml once daily (QD) were compared by propensity score matching analysis using individual patient data from ADVANCE and CONFIRM phase III clinical trials...

BACKGROUND AND AIM: Peginterferon beta-1a (Plegridy) offers the advantage of a prolonged half-life with less-frequent administration and a higher patient adherence. However, the use of an interferon may lead to flu-like symptoms (FLS) and injection-site reactions (ISR) that results in drug discontinuation. The objective of this Delphi analysis was to obtain consensus on the characteristics and management of FLS/ISR of peginterferon beta-1a in patients with relapsing-remitting MS based on real-world clinical experiences...

OBJECTIVE: To understand how longitudinal serum neurofilament light chain (sNfL) patterns can inform its use as a prognostic biomarker in multiple sclerosis (MS) and evaluate whether sNfL reflects MS disease activity and disease-modifying therapy usage. METHODS: This was a post hoc analysis of longitudinal data and samples from the ADVANCE trial (NCT00906399) of patients with relapsing-remitting MS (RRMS). sNfL was measured every 3 months for 2 years, then every 6 months for 4 years...

Interferon beta (IFNβ) was the first disease-modifying therapy available to treat multiple sclerosis (MS), providing patients with a treatment that resulted in reduced relapse rates and delays in the onset of disability. Four IFNβ drugs are currently approved to treat relapsing forms of MS: subcutaneous (SC) IFNβ-1b, SC IFNβ-1a, intramuscular IFNβ-1a, and, most recently, SC peginterferon beta-1a. Peginterferon beta-1a has an extended half-life and requires less frequent administration than other available treatments (once every 2 weeks vs every other day, 3 times per week, or weekly)...

Background: Multiple sclerosis (MS) is a rare, long-standing, and disabling disease that affects the central nervous system and causes several clinical manifestations. As a result, this disease is associated with a high societal economic burden. Objective: To analyze the trends in drug expenditure, utilization, and cost of specialty drugs for the treatment of patients with MS in the US Medicaid program. Methods: In this retrospective drug utilization research analysis, we obtained prescription data and reimbursement of disease-modifying therapies for MS from the Centers for Medicare & Medicaid Services Medicaid State Drug Utilization Data between January 2008 and December 2018...
