Background PASDAS is a composite index measuring disease activity in psoriatic arthritis (PsA), well correlated with HAQ and health related quality of life1.
Objectives To report the impact of secukinumab on individual core components of PASDAS and its relationship with function (HAQ-DI), health related quality of life (SF36-PCS and MCS, DLQI, PsAQoL) and fatigue in patients (pts) who achieved PASDAS low disease activity (LDA) vs. high disease activity (HDA) through Week (Wk) 104 using post-hoc analysis from FUTURE 2 trial.
Methods 397 pts with active PsA were randomised to s.c. secukinumab (300, 150, or 75mg) or placebo in FUTURE 2 study.2 PASDAS is derived from physician's global VAS, pts global VAS, SF-36 PCS, tender and swollen joints (TJC68 and SJC66), Leeds enthesitis count, dactylitis count and CRP level and has cut-points for HDA (≥5.4), LDA (<3.2) and remission (REM≤1.9).3 PASDAS was assessed at Wks 16, 52 and 104 and reported as observed using non-mutually exclusive categories at group level. Additionally, the SF-36 PCS, SF-36 MCS, HAQ-DI, FACIT-Fatigue, PsAQoL, and DLQI were assessed by PASDAS LDA and HDA at Wks 16, 52 and 104 using MMRM analyses.
Results Pts presented similar baseline characteristics. Mean±SD score of each PASDAS component among pts reaching LDA and HDA at Wk 16 for each treatment group are shown in table and were similar at Wk 104. Secukinumab treated pts achieving PASDAS LDA had significantly greater improvements in function, physical and mental health quality of life and fatigue compared to HDA through Wk 104 (Figure).
Conclusions In pts treated with secukinumab, the most improved individual components with PASDAS LDA were related to dactylitis, enthesitis, SF36-PCS, Physician global VAS and SJC at Wk 16 and Wk 104. PASDAS LDA was associated with better improvement in function, quality of life and fatigue than HDA confirming the importance to reach stringent target in a PsA pts with multifaceted disease.
