Slowing of brain atrophy with teriflunomide and delayed conversion to clinically definite MS.

BACKGROUND: We explored the effect of teriflunomide on cortical gray matter (CGM) and whole brain (WB) atrophy in patients with clinically isolated syndrome (CIS) from the phase III TOPIC study and assessed the relationship between atrophy and risk of conversion to clinically definite MS (CDMS). METHODS: Patients (per McDonald 2005 criteria) were randomized 1:1:1 to placebo, teriflunomide 7 mg, or teriflunomide 14 mg for ⩽108 weeks (core study). In the extension, teriflunomide-treated patients maintained their original dose; placebo-treated patients were re-randomized 1:1 to teriflunomide 7 mg or 14 mg. Brain volume was assessed during years 1-2. RESULTS: Teriflunomide 14 mg significantly slowed annualized CGM and WB atrophy versus placebo during years 1-2 [percent reduction: month 12, 61.4% (CGM; p = 0.0359) and 28.6% (WB; p = 0.0286); month 24, 40.2% (CGM; p = 0.0416) and 43.0% (WB; p < 0.0001)]. For every 1% decrease in CGM or WB volume during years 1-2, risk of CDMS conversion increased by 14.5% (p = 0.0004) and 47.3% (p < 0.0001) during years 1-2, respectively, and 6.6% (p = 0.0570) and 35.9% (p = 0.0250) during years 1-5. In patients with the least (bottom quartile) versus most (top quartile) atrophy during years 1-2, risk of CDMS conversion was reduced by 58% (CGM; p = 0.0024) and 58% (WB; p = 0.0028) during years 1-2, and 42% (CGM; p = 0.0138) and 29% (WB; p = 0.1912) during years 1-5. CONCLUSION: These findings support the clinical relevance of CGM and WB atrophy and early intervention with teriflunomide in CIS.

Teriflunomide real-world evidence: Global differences in the phase 4 Teri-PRO study.

BACKGROUND: The demographics and management of patients with multiple sclerosis (MS) differ across geographical regions, but it is unclear whether/how these differences affect treatment outcomes. The aim of this post-hoc analysis was to assess teriflunomide use and patient-reported outcomes in the United States (US) and the rest of the world (ROW) in the phase 4 Teri-PRO study (NCT01895335). METHODS: In the phase 4, real-world, Teri-PRO study, patients with relapsing forms of MS received teriflunomide for 48 weeks according to local labeling. The primary endpoint was treatment satisfaction measured using the Treatment Satisfaction Questionnaire for Medication Version 1.4 (TSQM 1.4). Secondary endpoints included scores on the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Performance Scale (MSPS), and Patient-Determined Disease Steps (PDDS), and occurrence of adverse events. Primary and secondary endpoints were assessed at baseline and Week 48. An exploratory subgroup analysis assessed PROs in the black patient population. RESULTS: The US and ROW groups included 545 and 455 patients, respectively. The mean age of patients in the ROW group was lower, they had a shorter mean time since first symptoms of MS, and had lower mean EDSS scores at baseline, compared with the US group (all p < 0.0001). Black patients made up 9% of US patients vs 0.2% of ROW patients. TSQM global satisfaction scores and effectiveness, side effects, and convenience subscale scores were significantly improved from baseline to Week 48 (all p < 0.0001). Disability measures were stable from baseline to Week 48 for both groups, despite different baseline level scores between the two groups. The overall proportion of patients who experienced an AE was similar across both groups. Fewer patients in the US group vs the ROW group reported hair thinning (16.1% vs 31.2%). Black patients showed comparable baseline demographics and disease characteristics and similar change over time in PROs compared with the overall US group. CONCLUSION: Patient differences observed at baseline between the US and ROW groups suggest variation in teriflunomide prescribing practices in the real-world Teri-PRO study. Improvement in treatment satisfaction and stability of disability measures were comparable between patients in the US and ROW. This suggests that teriflunomide was effective despite differences in baseline demographics and possible cultural and management differences between these geographical regions.

Real-World Observational Evaluation of Hair Thinning in Patients with Multiple Sclerosis Receiving Teriflunomide: Is It an Issue in Clinical Practice?

INTRODUCTION: Hair thinning occurred in 10-14% of teriflunomide-treated patients in the teriflunomide multiple sclerosis clinical development program, compared with 5% of placebo-treated patients. Our objective was to examine the clinical course of hair thinning in patients in an observational real-world project. METHODS: Patients with relapsing-remitting multiple sclerosis who reported hair thinning to healthcare professionals (HCPs) during treatment with teriflunomide were eligible for inclusion. During two office visits, one at onset of hair thinning and another at follow-up, HCPs and patients completed questionnaires that categorized hair thinning as mild, moderate, or severe, or from 0 (no hair thinning) to 10 (very severe hair thinning), respectively. At the follow-up visit, patients also rated the degree of recovery. Patients were photographed at both visits with a standardized protocol and camera. RESULTS: Of the 38 patients who completed follow-up, most were women (97%) without prior history of hair thinning (87%), with the majority (68%) receiving concomitant medications potentially associated with hair thinning. The mean time to onset of hair thinning was 77 days after the first teriflunomide dose. HCPs classified the majority of hair thinning events as mild (63%) or moderate (34%), with one event classified as severe (3%). The mean patient severity perception was 5/10, and complete/near-complete resolution or marked improvement was reported by 79% of patients. CONCLUSION: Consistent with observations from the teriflunomide clinical program, hair thinning was usually mild and occurred within the first 3 months of treatment, with most patients fully recovering while remaining on teriflunomide treatment. As with any potential adverse event, it is important to ensure appropriate expectations through patient education before treatment. FUNDING: Sanofi.

Patient-reported outcomes in patients with relapsing forms of MS switching to teriflunomide from other disease-modifying therapies: Results from the global Phase 4 Teri-PRO study in routine clinical practice.

BACKGROUND: Patient-reported outcomes (PROs) can assist clinicians in understanding the impact of disease-modifying therapy (DMT) on the daily lives of patients with multiple sclerosis (MS). With an increased number of DMTs becoming available, patients are now switching treatments more frequently in clinical practice. The effects of switching DMTs on a patient's daily life and their disease course may be reflected in PROs. The global, multicenter, open-label, phase 4 Teri-PRO study (NCT01895335), which was conducted in routine clinical practice, previously showed statistically and clinically significant increases in patient-reported treatment satisfaction in patients switching to teriflunomide from other DMTs. The impact of switching to teriflunomide from other DMTs on treatment satisfaction and a range of additional PROs was also evaluated. METHODS: Patients with relapsing forms of MS (N = 1000) received teriflunomide for 48 weeks per local labeling. Outcomes assessed in this analysis included treatment satisfaction (as measured by Treatment Satisfaction Questionnaire for Medication [Version 1.4]), disability worsening (as measured using the Expanded Disability Status Scale [EDSS] score, the Patient-Determined Disease Steps scale, and the Multiple Sclerosis Performance Scale), cognition (as measured using the Symbol Digit Modalities Test [SDMT]), treated relapses, quality of life (as measured by the Multiple Sclerosis International Quality of Life [MusiQoL] questionnaire and the Stern Leisure Activity Scale), and safety/tolerability over the course of the study in the subgroup of patients switching to teriflunomide from another DMT (n = 594). RESULTS: Patients reported significant improvements in treatment satisfaction scores following the switch to teriflunomide regardless of the reason for treating with teriflunomide (Global Satisfaction, disease worsening: baseline, 46.0, Week 48, 65.1; convenience: baseline, 57.4, Week 48, 72.4; intolerance: baseline, 50.9, Week 48, 71.1; side effects: baseline, 49.7, Week 48, 67.2; P < 0.0001 in all comparisons). These patients also showed improvement or stability in PROs evaluating disability worsening, cognition, and quality of life (EDSS: baseline, 3.1, Week 48, 3.0; SDMT: baseline, 0.975, Week 48, 0.978; MusiQoL: baseline, 67.5, Week 48, 69.5). The safety and tolerability profile of teriflunomide was consistent with that observed in other teriflunomide clinical trials. CONCLUSION: This analysis of the Teri-PRO study demonstrates the value of switching to teriflunomide from other DMTs in a real-world, clinical practice setting. The high levels of treatment satisfaction associated with teriflunomide in Teri-PRO may lead to improved adherence and thus improved outcomes.

Patient-reported outcomes in relapsing forms of MS: Real-world, global treatment experience with teriflunomide from the Teri-PRO study.

BACKGROUND: Patient-reported outcomes (PROs) provide clinicians with further understanding of the impact of treatment on patients' daily lives. In addition, real-world studies, which employ broader inclusion criteria than randomized trials, may help to inform prescribing decisions when selecting a disease-modifying therapy (DMT) to treat relapsing forms of MS (RMS). We sought to use PROs to determine patient treatment satisfaction and other treatment outcomes, and report safety and tolerability associated with teriflunomide, in the global, phase 4 Teri-PRO study (NCT01895335). METHODS: Patients with RMS (N = 1000) received teriflunomide for 48 weeks per local labeling. The primary endpoint was Global Satisfaction with teriflunomide treatment measured by the Treatment Satisfaction Questionnaire for Medication (TSQM, V1.4). Secondary endpoints included TSQM scores at Week (W)48 vs baseline in patients switching to teriflunomide from other DMTs ('switchers'), additional PROs, and safety. RESULTS: Mean TSQM Global Satisfaction score at W48 was high (68.2). Switchers reported significant improvements across all four TSQM domains at W48 vs baseline (all p < 0.0001). Adverse events were consistent with teriflunomide clinical trials. CONCLUSION: Patients reported high treatment satisfaction with teriflunomide, with switchers also reporting improved treatment satisfaction vs baseline. High treatment satisfaction in patients with RMS may lead to improved adherence, and hence treatment outcomes.

Teriflunomide slows BVL in relapsing MS: A reanalysis of the TEMSO MRI data set using SIENA.

OBJECTIVE: To assess, using structural image evaluation using normalization of atrophy (SIENA), the effect of teriflunomide, a once-daily oral immunomodulator, on brain volume loss (BVL) in patients with relapsing forms of MS enrolled in the phase 3 TEMSO study. METHODS: TEMSO MR scans were analyzed (study personnel masked to treatment allocation) using SIENA to assess brain volume changes between baseline and years 1 and 2 in patients treated with placebo or teriflunomide. Treatment group comparisons were made via rank analysis of covariance. RESULTS: Data from 969 patient MRI visits were included in this analysis: 808 patients had baseline and year 1 MRI; 709 patients had baseline and year 2 MRI. Median percentage BVL from baseline to year 1 and year 2 for placebo was 0.61% and 1.29%, respectively, and for teriflunomide 14 mg, 0.39% and 0.90%, respectively. BVL was lower for teriflunomide 14 mg vs placebo at year 1 (36.9% relative reduction, p = 0.0001) and year 2 (30.6% relative reduction, p = 0.0001). Teriflunomide 7 mg was also associated with significant reduction in BVL vs placebo over the 2-year study. The significant effects of teriflunomide 14 mg on BVL were observed in both patients with and without on-study disability worsening. CONCLUSIONS: The significant reduction of BVL vs placebo over 2 years achieved with teriflunomide is consistent with its effects on delaying disability worsening and suggests a neuroprotective potential. CLASSIFICATION OF EVIDENCE: Class II evidence shows that teriflunomide treatment significantly reduces BVL over 2 years vs placebo. CLINICALTRIALSGOV IDENTIFIER: NCT00134563.
