Objective. To evaluate the efficacy and safety of intraarticular sprifermin (recombinant human fibroblast growth factor 18) in the treatment of symptomatic knee osteoarthritis (OA).Methods. The study was a randomized, doubleblind, placebo-controlled, proof-of-concept trial. Intraarticular sprifermin was evaluated at doses of 10 g, 30 g, and 100 g. The primary efficacy end point was change in central medial femorotibial compartment cartilage thickness at 6 months and 12 months as determined using quantitative magnetic resonance imaging (qMRI). The primary safety end points were nature, incidence, and severity of local and systemic treatment-emergent adverse events (AEs) and acute inflammatory reactions, as well as results of laboratory assessments. Secondary end points included changes in total and compartment femorotibial cartilage thickness and volume as assessed by qMRI, changes in joint space width (JSW) seen on radiographs, and pain scores on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results. One hundred ninety-two patients were randomized and evaluated for safety, 180 completed the trial, and 168 were evaluated for the primary efficacy end point. We found no statistically significant dose response in change in central medial femorotibial compartment cartilage thickness. Sprifermin was associated with statistically significant, dose-dependent reductions in loss of total and lateral femorotibial cartilage thickness and volume and in JSW narrowing in the lateral femorotibial compartment. All groups had improved WOMAC pain scores, with statistically significantly less improvement at 12 months in patients receiving the 100-g dose of sprifermin as compared with those receiving placebo. There was no significant difference in serious AEs, treatment-emergent AEs, or acute inflammatory reactions between sprifermin and placebo groups. Conclusion. No statistically significant relation-ClinicalTrials.gov identifier: NCT01033994.

Objective: To evaluate the effectiveness and tolerability of lacosamide added to one or two antiepileptic drugs (AEDs) in the treatment of patients with brain tumor-related epilepsy (BTRE), and to evaluate patients' global impression of change and quality of life (QoL). Methods: This was a prospective, multicenter, single-arm, noninterventional study with a 6-month observation period (EP0045; NCT02276053). Eligible patients (≥16 years old) had active BTRE secondary to low-grade glioma (World Health Organization grade 1 and 2) and were receiving treatment with one or two AEDs at baseline. Lacosamide was initiated by the treating physician in the course of routine clinical practice. Primary outcomes were 50% responders (≥50% reduction in focal seizure frequency from baseline) and Patient's Global Impression of Change (PGIC) at month 6. Secondary outcomes included seizure-free status and Clinical Global Impression of Change (CGIC) at month 6, change in QoL (5-Level EuroQol-5 Dimension Quality of Life Assessment) and symptom outcomes (MD Anderson Symptom Inventory-Brain Tumor) from baseline to month 6, and Kaplan-Meier estimated 6-month retention on lacosamide. Safety variables included adverse drug reactions (ADRs). Results: Patients were recruited from 24 sites in Europe. Ninety-three patients received lacosamide (mean [standard deviation] age = 44.5 [14.7] years; 50 [53.8%] male; median baseline focal seizure frequency = five seizures/28 days [range = 1-280]), of whom 79 (84.9%) completed the study. At 6 months, 66 of 86 (76.7%) patients were 50% responders and 30 of 86 (34.9%) were seizure-free. Improvements on PGIC were reported by 49 of 76 (64.5%) patients. Based on CGIC, 52 of 81 (64.2%) patients improved. QoL and symptoms outcome measures remained stable. 648 | RUDÀ et al.

Background: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. Objectives: To assess patients' ability to self-inject bimekizumab subcutaneously using a 1 mL safety syringe or auto-injector. Methods: DV0002 and DV0006 were sub-studies of BE BRIGHT, a multicenter, phase 3 open-label extension study. Patients with moderate to severe plaque psoriasis received bimekizumab 320 mg (2x160 mg injections) every 4 or 8 weeks and were randomized 1:1 to the safety syringe or the auto-injector. The ability of patients to safely and effectively self-inject bimekizumab was assessed at 8 weeks (primary endpoint) and immediately after self-injection training at Baseline (secondary endpoint). Patient experience was evaluated using the pain visual analog scale (VAS; 0-100 mm; 100 being worst pain), and the Self-Injection Assessment Questionnaire (SIAQ; 0-10; 10 being most positive experience). Results: All evaluable patients in DV0002 (n=125) and DV0006 (n=86) safely and effectively self-injected bimekizumab at Week 8. All evaluable patients in DV0002 who used the safety syringe (n=64) and 97.1% (n=66/68) who used the auto-injector, as well as all evaluable DV0006 patients (n=88) also self-injected bimekizumab safely and effectively at Baseline. Median VAS scores were low (range: 7.0-20.0), and median pre-injection and post-injection SIAQ scores were high (range: 5.

Given the increasing interest in treatment satisfaction research and the lack of a specific questionnaire in osteoarthritis (OA), we developed and explored the psychometric properties of the osteoARthritis Treatment Satisfaction (ARTS) questionnaire. The ARTS questionnaire which consists of 18 items was developed in French following the analysis of semi-structured interviews performed among 20 OA participants, five rheumatologists and five general practitioners. Psychometric properties were assessed in France on a cross-sectional sample of 797 OA participants and test-retest reliability was evaluated in an independent sample of 111 clinically stable OA participants who filled-in the questionnaire within a 7.7 (+/- 3.1) day interval. Using principal component analysis, four scales were identified: Treatment advantages (seven items), Treatment convenience (three items), Treatment confidence (two items) and Satisfaction with physician (six items). Item convergent and item discriminant validity were satisfactory. Internal consistency provided evidence of reliability and lack of redundancy (Cronbach's alphas ranged from 0.66 to 0.86). Test-retest reliability was acceptable for two out of four scales (intraclass correlations coefficients (ICC) ranged from 0.61 to 0.75). Significant between groups differences were found on the ARTS scales, demonstrating the known groups validity of the ARTS questionnaire. The responsiveness of the ARTS is still to be documented.

Introduction Effects of antiepileptic drug (AED) load changes in patients with focal seizures have not been well evaluated. Methods SP1065 (NCT01673282) was a noninterventional, prospective, observational study conducted in a clinical practice setting. Patients (aged ≥18 years) with focal seizures were enrolled within 7 days of being prescribed adjunctive lacosamide. Observation period was ~6 months. Drug load was assessed using percentage change in ratio of actual prescribed dose and World Health Organization defined daily dose (DDD) for concomitant AEDs and all AEDs (including lacosamide). Subgroups were defined for patients with at least one concomitant sodium channel–blocking AED (SCB [+]) and those without (SCB [−]). Results A total of 311 patients were assessed for safety, 302 for measurement of drug load, and 240 for effectiveness. Ratio of AED dose to DDD decreased for concomitant AEDs (−9.6%) and increased for all AEDs (including lacosamide; 15.5%). Median reduction in focal seizure frequency per 28 days was 100% (range: −100, 2275.8). 70.4% and 61.7% of patients had a ≥50% or ≥75% reduction in seizure frequency, respectively; 50.8% became seizure‐free. In the SCB (+) subgroup (n = 149), ratio of AED dose to DDD decreased for concomitant AEDs (−15.0%) and increased for all AEDs (10.7%). In the SCB (−) subgroup (n = 153), ratio of AED dose to DDD decreased for concomitant AEDs (−4.4%) and increased for all AEDs (20.2%). Fifty‐seven patients (18.3%) reported ADRs, most commonly dose >400 mg/d (7.1%). Seventeen patients (5.5%) had ADRs leading to discontinuation. Significance Addition of lacosamide resulted in reduction of concomitant AED drug load regardless of whether concomitant AEDs were SCB (+) or SCB (−). These results indicate that addition of lacosamide in patients with focal seizures could allow clinicians to withdraw or reduce the dose of less well‐tolerated or less effective AEDs.

Rationale: Lacosamide (LCM) was initially approved in Taiwan in March 2014 for use as adjunctive therapy for focal impaired awareness seizures and secondarily generalized seizures (SGS) in patients with epilepsy ! 16 years of age. The efficacy and tolerability of adjunctive LCM for the treatment of patients with focal seizures have been demonstrated in randomized, placebo-controlled trials. However, the trials do not reflect a flexible dose setting. This study (EP0063) was conducted to assess the safety and tolerability of LCM in real-world clinical practice in Taiwan. Effectiveness of LCM was also assessed as an exploratory objective. Methods: EP0063 was a multicenter, prospective, noninterventional study with an expected observation period of 12 months ± 60 days. Eligible patients were ! 16 years of age, had focal impaired awareness seizures and/or SGS (in line with approved indication in Taiwan at the time of the study), were taking at least one concomitant antiseizure medication (ASM), and had at least one seizure in the 3 months before baseline. Patients were prescribed LCM by their treating physician in the course of routine clinical practice. The primary safety variable was treatment-emergent adverse events (TEAEs) spontaneously reported to, or observed by, the treating physician. Based on safety data from previous studies of LCM and known side effects of other ASMs, certain TEAEs (including but not limited to cardiac and electrocardiogram, suicidality, and rash related terms) were analyzed separately. Effectiveness variables included Clinical Global Impression of Change (CGIC) and change in 28-day seizure frequency from baseline to 12 months (or final visit), and freedom from focal seizures. Results: A total of 171 patients were treated with LCM, of whom 139 (81.3%) completed the study. The Kaplan-Meier estimated 12-month retention was 82.9%. Patients had a mean (standard deviation [SD], range) age of 38.5 (14.0, 16-77) years, and 96 (56.1%) were male. Patients were taking a mean (SD, range) of 2.8 (1.1, 1-6) ASMs at baseline. Mean (SD, range) duration of LCM treatment was 288.7 (111.9, 2-414) days, and the mean (SD, range) daily dosage of LCM was 205.0 (82.7, 50.0-505.2) mg/day. Overall, 95
