OBJECTIVES: To demonstrate the long-term impact of bimekizumab treatment on health-related quality of life (HRQoL) and work productivity to 3 years in patients with psoriatic arthritis (PsA).
METHODS: BE OPTIMAL (NCT03895203; biologic disease-modifying antirheumatic drug [bDMARD]-naïve) and BE COMPLETE (NCT03896581; tumour necrosis factor inhibitor inadequate response/intolerance [TNFi-IR]) assessed subcutaneous bimekizumab 160mg every 4 weeks in patients with PsA. Placebo patients switched to bimekizumab (placebo/bimekizumab) at Week16. Study completers could enter BE VITAL (open-label extension; NCT04009499).
HRQoL, physical function and work productivity were assessed using EQ-5D-3L visual analogue scale (VAS), Short Form 36-item Health Survey (SF-36) physical component summary (PCS) and Work Productivity and Activity Impairment (WPAI) Questionnaire, respectively.
Data reported for Bimekizumab Total (placebo/bimekizumab and bimekizumab-randomised patients) to Week148/Week156 (bDMARD-naïve/TNFi-IR) using observed case or multiple imputation.
RESULTS: Week148/156 completion for Bimekizumab Total patients: 555/712 (77.9%) bDMARD-naïve and 299/400 (74.8%) TNFi-IR. Mean baseline scores (SD): EQ-5D-3L VAS 56.5 (20.0; n=711) bDMARD-naïve, 54.4 (20.4; n=400) TNFi-IR; SF-36 PCS 37.6 (9.5; n=711), 36.3 (9.4; n=400); overall work impairment 35.9 (26.8; n=443), 40.5 (27.9; n=231) in employed patients.
Improvements from baseline in EQ-5D-3L VAS (CfB [SD]) sustained from Week52/40 (16.9 [26.9] bDMARD-naïve; 17.2 [27.2] TNFi-IR) to Week148/156 (17.3 [26.6] bDMARD-naïve; 17.2 [30.2] TNFi-IR).
Improvements from baseline in SF-36 PCS (CfB [95% CI]) sustained from Week52/40 (8.3 [7.5, 9.0] bDMARD-naïve; 8.2 [7.2, 9.2] TNFi-IR) to Week148/156 (8.4 [7.7, 9.1] bDMARD-naïve; 8.8 [7.8, 9.9] TNFi-IR).
Improvements from baseline in percent overall work impairment (CfB [95% CI]) sustained from Week52/40 (-18.4 [-21.4, -15.4] bDMARD-naïve; -21.5 [-25.3, -17.8] TNFi-IR) to Week148/156 (-17.3 [-20.6, -13.9] bDMARD-naïve; -21.3 [-26.2, -16.3] TNFi-IR). Similar improvements observed for presenteeism (impairment while working) and activity impairment.
CONCLUSIONS: Bimekizumab-treated patients with PsA demonstrated sustained improvements to 3 years in HRQoL, physical function and work productivity; improvements were consistent across bDMARD-naïve and TNFi-IR patients.
