<h3>Background</h3> The AbbVie Patient (pt) Support Program (PSP) is offered to pts prescribed adalimumab (ADA) for rheumatoid arthritis (RA) and other indications. <h3>Objectives</h3> This subanalysis evaluated the impact of ADA in achieving clinical, functional, and pt-reported outcome treatment targets and sustained responses by PSP use. <h3>Methods</h3> PASSION was a 78-wk postmarketing, multinational, observational study enrolling pts with moderate to severe RA receiving ADA in routine clinical care. Pts with an insufficient response to ≥1 disease modifying antirheumatic drug (DMARD; 1 prior biologic DMARD was allowed) and newly initiating ADA were enrolled. Pts were divided into 2 groups based on PSP participation: ever (PSP users) vs never (PSP non-users). Outcome measures included proportion of pts with low disease activity (LDA)/remission defined by Clinical Disease Activity Index (CDAI) ≤10, Simplified Disease Activity Index (SDAI) ≤11, and Disease Activity Score(DAS)28(C-reactive protein [CRP])≤3.2; proportion with mild to moderate disability (Health Assessment Questionnaire Disease Index [HAQ-DI] 0 to 1); and proportion with 20%/50%/70% improvement from baseline (BL) in ACR components (table 1). Missing values were imputed using last observation carried forward, and differences in proportions between PSP users and PSP non-users were compared with Chi-square tests. <h3>Results</h3> Of 1025 pts treated with ADA in the study, 499 were PSP users and 526 were PSP non-users. A significantly greater proportion of PSP users vs PSP non-users had LDA/remission as defined by CDAI at wks 24, 52, and 78 and as defined by SDAI or DAS28(CRP) at weeks 52 and 78 (p&lt;0.05 for all). A significantly greater proportion of PSP users vs PSP non-users also had mild to moderate disability defined by HAQ-DI at wk 78 (p=0.0239). Compared with PSP non-users, a significantly greater proportion of PSP users had 70% improvement from BL in PtGA, pain, and CRP at wks 24, 52, and 78; SJC28 at wks 52 and 78; and TJC28 and PhGA at wk 78 (table 1). At wks 24, 52, and 78, a significantly greater proportion of PSP users vs PSP non-users had 20% and 50% improvements from BL in all ACR components (all p&lt;0.05), except for 50% improvement from BL in TJC28 at wks 24 and 78 and PhGA at wk 24. <h3>Conclusions</h3> Among pts with moderate to severe RA initiating ADA treatment, participation in the PSP resulted in significantly greater improvements in clinical, functional, and pt-reported outcomes at wks 24, 52, and 78 in comparison to the PSP non-users. <h3>Acknowledgements</h3> AbbVie funded the study and analysis, and approved the abstract for submission.
