[Phase IV non-interventional studies in the treatment of rheumatoid arthritis with biologicals in Germany : real-life clinical practice data]

[Etanercept in routine German clinical practice to treat rheumatoid arthritis patients : A one-year observational study on effectiveness, safety and health economics]

BACKGROUND

The efficacy and safety of the TNF‑α inhibitor etanercept (ETA) as a treatment for rheumatoid arthritis (RA) is well established by randomized controlled trials. The purpose of this study was to evaluate the benefit yielded by ETA within the regular outpatient care.

PATIENTS AND METHODS

This prospective non-interventional trial included patients being treated with ETA. Data concerning efficacy, safety and life quality were collected over a period of 52 weeks. Statistical evaluation was done on a solely descriptive level.

RESULTS

From 329 specialized medical centres, 4945 patients were enrolled. Of all patients, 94.4% received a co-medication for RA, additionally to their treatment with ETA. At baseline, 22.1% of all patients fulfilled the criteria for functional remission according to the Funktionsfragebogen Hannover (FFbH) questionnaire (95% CI: 21.0-23.3%); at 52 weeks, functional remission rate accounted for 41.1% (last observation carried forward [LOCF], 95% CI: 39.4-42.9%). The disease activity score (DAS) DAS28 declined from 5.4 ± 1.3 (N = 4304) to 3.3 ± 1.4 (as observed; N = 2608). EuroQol EQ-5D, a measurement of health-related life quality issues, indicated an improvement on the visual analogue scale (VAS) from 53.1 ± 21.3 mm (N = 4718) at baseline to 70.0 ± 20.5 mm (as observed; N = 3036). Generally, ETA has been tolerated well. With regard to the safety profile specified by previous studies, no meaningful deviations concerning the nature, frequency or severity of adverse events were detected.

CONCLUSION

Based on a large number of patients and in a treatment context that is representative of routine outpatient care in Germany, it was confirmed that patients with RA may benefit from a treatment with ETA.

Patient-reported outcomes with golimumab in patients with rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis: non-interventional study GO-NICE in Germany

The TNF inhibitor golimumab (GLM) is a treatment option in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). The GO-NICE study assessed patient-reported outcomes (PRO) in patients newly treated with monthly GLM 50 mg subcutaneously (SC) under real-life conditions in Germany. A prospective non-interventional study with 24-month observation per patient was conducted at 158 sites. Available for analysis were 1,458 patients, 474 with rheumatoid arthritis (RA: 54.9 ± 13.4 years, 72.8% females, 60.4% biologic-naïve), 501 with psoriatic arthritis (PsA: 50.5 ± 12.1 years, 54.1% females; 47.5% biologic-naïve), and 483 with ankylosing spondylitis (AS: 43.6 ± 12.3 years, 66.5% males; 58.4% biologic-naïve). A total of 664 patients completed follow-up to month 24. An improvement of QoL by EuroQoL EQ-5D-3L was seen after 6 months and was maintained over 24 months. The patients’ health state today (EQ visual analog scale) improved statistically significantly (p < 0.0001 vs. BL) from 51.0 at baseline (BL) to 63.4 (RA), from 48.4 to 64.3 (PsA) and from 46.8 to 66.5 (AS). Functional ability (FFbH) improved significantly (p < 0.003 vs. BL) from BL 68.2 to 76.1 points (RA), from 69.0 to 76.8 points (PsA), and from 69.0 to 78.5 points (AS). The mean FACIT-Fatigue score increased significantly (p < 0.0001 vs. BL) from BL 32.4 to 38.3 points (RA), from 30.0 to 35.9 points (PsA), and from 29.9 to 37.9 points after 24 months (AS); p < 0.0001 vs. BL each. On treatment with GLM SC once monthly, significant improvements in patient-reported QoL parameters were noted in a very similar manner in all three diseases.

Treatment of Rheumatoid Arthritis with Certolizumab Pegol: Results from PROACTIVE, a Non-Interventional Study in the UK and Ireland

Introduction

The objective of this non-interventional study was to investigate the long-term safety and effectiveness of certolizumab pegol (CZP) in patients with rheumatoid arthritis (RA) in the UK and Ireland.

Methods

Patients were prescribed CZP at their physicians’ discretion and followed during routine clinical practice for up to 88 weeks. DAS28(ESR) response (defined as at least a 1.2-point reduction from baseline) was measured in the full analysis set (FAS) at week 12, and patients were categorized by week 12 responder status in all subsequent analyses. The primary outcome was DAS28(ESR) response at week 78. Secondary outcomes included change from baseline in DAS28(ESR), HAQ-DI, and RADAI scores at week 78, and EULAR response at week 78. Adverse drug reactions (ADRs) were recorded for all patients who received at least one dose of CZP.

Results

A total of 149 patients were enrolled, of whom 111 (74.5%) formed the FAS. At week 12, 80 patients (72.1%) were DAS28(ESR) responders and 31 (27.9%) non-responders. Compared to non-responders, a greater proportion of week 12 responders had a DAS28(ESR) response at week 78 (43.8% versus 22.6%). Improvements in DAS28(ESR), HAQ-DI, and RADAI scores were also greater on average among week 12 responders, as was the proportion of patients meeting EULAR criteria. Overall, 9 patients (6.1%) experienced 13 ADRs during the study.

Conclusion

These data demonstrate the safety and effectiveness of CZP in adult patients with RA treated during routine clinical practice in the UK and Ireland.
