Treatment satisfaction in patients with relapsing-remitting multiple sclerosis initiated on teriflunomide in routine clinical practice: Australian observational data

Clinical Practice Evidence of Treatment Satisfaction with Moderate and High-Efficacy Drugs in Multiple Sclerosis

Introduction

Generally, the choice of disease-modifying treatment (DMT) for people with multiple sclerosis (PwMS) is based on aspects of efficacy and safety. However, due to the diversity of drugs and the different routes of administration, it is essential to know the experience and satisfaction of PwMS. Patient- reported outcomes (PROs) help us to optimize and improve adherence.

Methods

Our objective with this cross-sectional, non-interventional study is to analyze satisfaction outcomes using the treatment satisfaction questionnaire for medication (TSQM) according to moderate or high efficacy of DMTs and the relationship with demographic, clinical and quality of life (QoL) aspects.

Results

PwMS receiving high-efficacy DMTs show greater overall satisfaction, but not in the other TSQM subscales. The route of administration did not show differences in treatment satisfaction. The best QoL scores were observed in patients treated with oral DMTs compared to injectables or infusions.

Discussion

The efficacy of DMT is a significant predictor of overall satisfaction. Quality of life has a minimal impact on overall satisfaction. EDSS, treatment duration and fatigue (MFIS) were not significant predictors of satisfaction outcomes. The knowledge provided by the PROs allows healthcare professionals to better understand the preferences and needs of PwMS, adjusting therapeutic strategies, improving patient experience and treatment effectiveness.

The patient-reported outcomes for the new brand-generic teriflunomide in relapsing-remitting multiple sclerosis

BACKGROUND

Patient-reported outcomes (PROs) provide valuable insights into the impact of disease-modifying therapies (DMTs) on patients' daily lives and disease progression. This study evaluates treatment satisfaction and tolerability among patients using a brand-generic Teriflunomide (Tebazio®, 14 mg tablet) manufactured by Zistdaru Danesh Biopharmaceuticals.

MATERIALS AND METHODS

A Phase IV observational study was conducted on patients with Relapsing-Remitting Multiple Sclerosis (RRMS) who were either initiated on or switched to Teriflunomide 14 mg. The primary focus was on the medication's safety. Patient satisfaction was measured using the Treatment Satisfaction Questionnaire for Medication [Version 1.4] (TSQM-14). Additionally, medication adherence and discontinuation rates were monitored.

RESULTS

Of the 235 RRMS patients enrolled, participated in this study, all received the Teriflunomide treatment orally on a daily basis. Over the 18-month follow-up period, 25.96 % of patients discontinued the treatment. Discontinuation was mainly due to adverse events (11 %), lack of patient willingness to continue (12.7 %), and disease progression (4.2 %). The most commonly reported adverse events included dermatologic disorders, elevated liver enzymes, and gastrointestinal issues. TSQM-14 scores demonstrated significant improvements over the 18-month period. A high medication adherence rate of 98.1 % was also recorded.

CONCLUSION

Patients reported notable satisfaction with Teriflunomide, as reflected in their TSQM scores, which suggests a likelihood of improved patient adherence. The 14 mg brand-generic Teriflunomide was well-accepted by Iranian RRMS patients, with no significant concerns arising during the study. These findings also highlight the significance of patient-reported outcomes in DMTs, with potential benefits for adherence and clinical practice.

Evaluation of therapy satisfaction with cladribine tablets in patients with RMS: Final results of the non-interventional study CLEVER

BACKGROUND

Cladribine tablets for the treatment of relapsing multiple sclerosis (RMS) are administered in two pulsed treatment courses in two consecutive years, totalling a maximum of 20 treatment days. Here we present data collected shortly after the launch of cladribine tablets, focusing on the patient's perspective. The objective was to investigate patients' perceived effectiveness, tolerability, and convenience, as well as global satisfaction of and with cladribine tablets.

METHODS

CLEVER was a non-interventional multicentre study conducted in Germany from 12/2017 to 7/2020. Adult patients with RMS initiating therapy with cladribine tablets were included. Observation time per patient was 24 weeks, comprising 3 visits (baseline, week 4 and 24). The primary endpoint was overall treatment satisfaction at week 24, assessed by the Treatment Satisfaction Questionnaire for Medication 14 items (TSQM 1.4). Subgroup analyses included stratification by prior treatment.

RESULTS

In total, 491 patients (69.2 % female; mean (±SD) age 40.3 (±11.5) years, 85.1 % pre-treated, median EDSS 2.5) initiated therapy with cladribine tablets and were included in the analysis. At week 24, the mean (±SD) global TSQM satisfaction score was 75.6 (±19.0). For patients switching from either injectables or oral medication, the change in therapy satisfaction from baseline to week 24 was positive in all TSQM domains with clinically meaningful effect sizes in the global satisfaction and side effects domains. Most patients (85.5 %) remained relapse-free over 24 weeks. Out of 491 patients, 187 (38.1 %) experienced at least one adverse event and 8 patients (1.6 %) one serious adverse event.

CONCLUSION

Treatment satisfaction with cladribine tablets was high. The switch from prior injectables or oral medication translated into increased treatment satisfaction at week 24 with clinically meaningful effects in the global satisfaction and side effects domains. Effectiveness and safety were consistent with results from clinical studies.

Establishing clinically meaningful within-individual improvement thresholds for eight patient-reported outcome measures in people with relapsing-remitting multiple sclerosis

BACKGROUND

As disease-modifying therapies do not reverse the course of multiple sclerosis (MS), assessment of therapeutic success involves documenting patient-reported outcomes (PROs) concerning health-related quality of life, disease and treatment-related symptoms, and the impact of symptoms on function. Interpreting PRO data involves going beyond statistical significance to calculate within-patient meaningful change scores. These thresholds are needed for each PRO in order to fully interpret the PRO data. This analysis of PRO data from the PROMiS AUBAGIO study, which utilized 8 PRO instruments in teriflunomide-treated relapsing-remitting MS (RRMS) patients, was designed to estimate clinically meaningful within-individual improvement thresholds in the same manner, for 8 PRO instruments.

RESULTS

The analytical approach followed a triangulation exercise that considered results from anchor- and distribution-based methods and graphical representations of empirical cumulative distribution functions in PRO scores in groups defined by anchor variables. Data from 8 PRO instruments (MSIS-29 v2, FSMC, MSPS, MSNQ, TSQM v1.4, PDDS, HRPQ-MS v2, and HADS) were assessed from 434 RRMS patients. For MSIS-29 v2, FSMC, MSPS, and MSNQ total scores, available anchor variables enabled both anchor- and distribution-based methods to be applied. For instruments with no appropriate anchor available, distribution-based methods were applied. A recommended value for meaningful within-individual improvement was defined by comparing mean change in PRO scores between participants showing improvement of one or two categories in the anchor variable or those showing no change. A "lower bound" estimate was calculated using distribution-based methods. An improvement greater than the lower-bound estimate was considered "clinically meaningful".

CONCLUSION

This analysis produced estimates for assessing meaningful within-individual improvements for 8 PRO instruments used in MS studies. These estimates should be useful for interpreting scores and communicating study results and should facilitate decision-making by regulatory and healthcare authorities where these 8 PROs are commonly employed.

Teriflunomide: an oral therapy for first-line treatment of children and adolescents living with relapsing-remitting multiple sclerosis

INTRODUCTION

Different disease-modifying therapies (DMTs) have been developed to slow down the progression of pediatric multiple sclerosis (MS). Teriflunomide is one such DMT that has recently been approved for use in pediatric MS in the European Union.

AREAS COVERED

The article provides an introduction to the mechanism of action of teriflunomide, reviews the clinical trials conducted on the safety and efficacy of the drug, and the optimal dosing and monitoring strategies.

EXPERT OPINION

Teriflunomide is an oral medication that has shown promise in improving outcomes for pediatric MS patients, including reduced relapse rates and improved quality of life. However, more research is needed to determine its long-term safety in pediatric patients. As MS often presents with an aggressive course in children, the choice of disease-modifying treatment should be carefully evaluated, with a preference for second-line therapy. Despite the potential benefits of teriflunomide, changes in clinical practice may be hindered by factors such as cost and physician familiarity with alternative treatments. Longer-term studies and biomarker identification are areas for improvement, but the future of research in this area holds promise for the continued development and refinement of disease-modifying therapies and more personalized, targeted treatments for pediatric MS patients.
