Psoriatic arthritis (PsA) is a chronic, systemic inflammatory disease. This study assessed the cost-effectiveness of secukinumab, an interleukin-17A inhibitor, versus other biologics in PsA from the Argentinean social security perspective. A semi-Markov model evaluated subcutaneous (sc) treatment with secukinumab 150 mg and 300 mg against other sc treatments such as adalimumab, certolizumab pegol, etanercept, golimumab, ustekinumab, and intravenous treatment infliximab in biologic-naïve (with or without moderate to severe psoriasis) and biologic-experienced PsA patients over a lifetime horizon. Response to treatments was determined using the PsA Response Criteria (PsARC) at 12 weeks. Model inputs were derived from randomized controlled trials, network meta-analyses, published literature, and other Argentinean sources. Model outcomes included quality-adjusted life years (QALYs) gained and incremental cost-effectiveness ratios. Sensitivity analyses and alternative scenarios with a higher cost option were also conducted. Among biologic-naïve PsA patients without psoriasis, secukinumab 150 mg provided the highest QALYs (7.18) versus all sc biologics at the lowest cost ($3 755 678 Argentine peso), thus dominating them. Among biologic-naïve PsA patients with psoriasis and biologic-experienced PsA patients, secukinumab 300 mg provided highest QALYs (6.99 and 7.53, respectively), dominated infliximab, and was cost-effective versus other sc biologics. Deterministic sensitivity analyses indicated sensitivity of results to variation in PsARC rates, drug acquisition costs, Health Assessment Questionnaire change, and utilities. A probabilistic sensitivity analysis showed maximum net monetary benefits with both secukinumab doses. Results from an alternative scenario analysis were similar to base-case analysis. For both biologic-naïve and experienced PsA patients, secukinumab is either a dominant or cost-effective treatment option compared with other biologics in Argentina. • Introduction of biologics in the treatment of psoriatic arthritis has significantly altered the treatment paradigm, leading to better disease management and improvement in the quality of life of patients. • Biologic treatments are costly and hence it is important to evaluate the cost-effectiveness of these treatments considering the finite healthcare resources. • Multiple cost-effectiveness studies and multiple technology assessments have evaluated the impact of biologic treatments (adalimumab, golimumab, etanercept, certolizumab pegol, ustekinumab, and infliximab) in active psoriatic arthritis patients in many countries. • This is the first-ever study that assessed the cost-effectiveness of secukinumab in psoriatic arthritis in Argentina. • For both biologic-naïve and experienced patients, secukinumab at 150- and 300-mg doses was either a dominant or cost-effective treatment option compared with other biologics.

• DAPSA-REM/LDA and VLDA/MDA were compared in tofacitinib-treated patients with PsA. • Agreement for DAPSA-REM with VLDA, and DAPSA-LDA with MDA, was moderate (months 1–6). • Reaching DAPSA-REM/LDA and VLDA/MDA were associated with improved HAQ-DI/SF-36 PCS. • Reaching DAPSA-REM/LDA and VLDA/MDA were associated with less structural damage. • DAPSA-REM/LDA and VLDA/MDA are useful for evaluating treatment response in PsA. To compare achievement of Disease Activity Index in Psoriatic Arthritis (DAPSA) remission (REM)/low disease activity (LDA) with very low disease activity (VLDA)/minimal disease activity (MDA) targets in tofacitinib-treated patients with psoriatic arthritis (PsA). In this post hoc analysis, data were pooled from two phase 3 studies (6 months' [NCT01882439] and 12 months' [NCT01877668] duration) of patients with PsA receiving tofacitinib 5 or 10 mg twice daily. Cut-offs for DAPSA targets: ≤4 for clinical REM and >4–≤14 for LDA. VLDA and MDA were defined as meeting 7 or ≥5, respectively, of 7 criteria. An ordered logistic regression model was performed to evaluate associations between baseline characteristics and achievement of DAPSA targets as well as VLDA/MDA at month 3. Agreement between achieving DAPSA and VLDA/MDA targets at months 1–6 was assessed via kappa tests. Change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) and Short Form-36 Health Survey (SF-36) Physical Component Summary (PCS) scores (month 6), modified Total Sharp Score (mTSS) and proportion of radiographic non-progressors (mTSS ≤0.5) at month 12 (NCT01877668 only) were compared across DAPSA and VLDA/MDA targets. Increased disease activity at baseline was associated with reduced likelihood of achieving DAPSA-REM/DAPSA-LDA or VLDA/MDA at month 3. There was moderate agreement (kappa values 0.41–0.60) between DAPSA-REM and VLDA, and DAPSA-LDA and MDA, from months 1 to 6, although over half of patients achieving DAPSA-REM and over two thirds of patients achieving DAPSA-LDA, respectively, were not captured by VLDA and MDA. Achieving DAPSA-REM/DAPSA-LDA or VLDA/MDA was associated with improved HAQ-DI and SF-36 PCS scores at month 6, and slightly reduced radiographic progression at month 12. This analysis of data from tofacitinib-treated patients with PsA demonstrated moderate agreement between the DAPSA and VLDA/MDA composite instruments. In agreement with previous studies, VLDA and MDA may be more difficult to achieve than DAPSA-REM and DAPSA-LDA, respectively. However, the clinical and prognostic relevance of this finding should be determined. These data support DAPSA and VLDA/MDA as useful tools for evaluating disease activity and treatment response in PsA. NCT01882439; NCT01877668 [ABSTRACT FROM AUTHOR]
