Background/Purpose: Secukinumab, a fully human anti–IL-17A monoclonal antibody, previously demonstrated higher minimal disease activity (MDA)1 response rates and sustained improvements in patient reported outcomes2 among active psoriatic arthritis (PsA) patients (pts) through Week (Wk) 52 in the FUTURE 2 study. This post-hoc analysis is further exploring the impact of secukinumab on individual components of MDA and its relationship with patient-reported outcomes among those who achieved or did not achieve MDA response through Wk 52.
Methods: 397 pts with active PsA were randomized to subcutaneous (s.c) secukinumab (300 mg, 150 mg, or 75 mg) or placebo at baseline, Wks 1, 2, and 3, and every 4 wks (q4w) from Wk 4.2 Pts were considered in MDA when they met at least 5 of 7 pre-defined criteria.1 The proportion of pts achieving each individual criterion of MDA and the proportion of pts achieving all seven criteria of MDA were calculated at Wks 24 and 52. Additionally, SF-36 MCS, SF-36 PCS, FACIT-Fatigue, PsAQoL, and DLQI were assessed in MDA responders and non-responders at Wks 24 and 52 using mixed-model for repeated measures (MMRM) analyses.
Results: In the pooled secukinumab (300 mg and 150 mg) MDA responder group, tender entheseal points ≤1 (96%), HAQ-DI ≤0.5 (95%), and PASI ≤1 (91%) were the individual components of MDA that consistently achieved the greatest response rates followed by swollen joint count ≤1 (87%), patient global VAS ≤20 (87%), tender joint count ≤1 (80%), and patient pain VAS ≤15 (78%) at Wk 24. A similar trend for the pooled secukinumab MDA responder group was observed at Wk 52. Among the MDA responders 40% (27/68) and 33% (30/93) met all of the seven components at Wks 24 and 52, respectively in the overall study population. Greater improvements in SF-36 MCS and PCS, PsAQoL, FACIT Fatigue, and DLQI scores were seen among MDA responders compared to non-responders at Wks 24 and 52 (Figure).
Conclusion: In pts treated with secukinumab, the individual components most frequently associated with MDA response were related to enthesitis, skin, and functional status and the arthritis-related components were also achieved by many pts. A high proportion of pts achieved and maintained their MDA response through Wk 52 and amongst those 33 to 40% were able to meet 7/7 MDA criteria. Achieving MDA with secukinumab was associated with greater patient-reported quality of life outcomes indicating MDA may be a patient-relevant outcome References: 1. Coates LC et al. Ann. Rheum.
