IVT-AFL 2q8 versus ranibizumab 0.5q4, and an indirect comparison of IVT-AFL 2q8 with ranibizumab 0.5PRN data. A de novo health economic model combined these clinical inputs with Dutch-specific costs associated with treatment, monitoring, and indirect caregiving, and utility inputs relevant to a Dutch population. Total quality-adjusted life-years (QALYs) and costs were calculated over a 15-year horizon. Uncertainty around the outcomes was tested through sensitivity analyses. Results: Compared with ranibizumab 0.5q4, a 2-year treatment IVT-AFL is associated with a significantly lower cost of € 7337 (95% CI: € 7248-€ 7435) over a 15-year horizon. There is no significant difference in QALYs (-0.0027 [95% CI: -0.0057 to 0.0001]). IVT-AFL 2q8 also has significantly lower total costs than ranibizumab 0.5PRN (€ 2450 [95% CI: € 2349-€ 2549]), with a nonsignificant gain of 0.0007 QALYS (95% CI: -0.0023 to 0.0036). Probabilistic analyses show that, due to its lower costs, IVT-AFL 2q8 treatment had an estimated > 99% probability of being cost-effective compared with both of the ranibizumab treatment strategies at a willingness-to-pay threshold of € 20,000 per QALY, the proposed informal Dutch threshold. The univariate analyses did not alter the conclusions. ConClusions: The analysis showed that IVT-AFL 2q8 treatment is associated with cost savings versus ranibizumab 0.5q4 or 0.5PRN. There is no significant difference in total QALYs between the treatments. Due to lower overall costs, IVT-AFL is a costeffective treatment option for wAMD patients in the Netherlands.

Background Apremilast (APR), an oral phosphodiesterase 4 inhibitor, works intracellularly to regulate inflammatory mediators. The Work Limitations Questionnaire (WLQ) is a reliable tool for assessing work productivity in patients with chronic health conditions. PALACE 1 compared the efficacy and safety of APR with placebo (PBO) in patients with active psoriatic arthritis (PsA) despite prior conventional disease-modifying antirheumatic drugs (DMARDs) and/or biologics. Objectives Assess the effect of APR on work productivity and work limitations in the PALACE 1 study. Methods Patients were randomized 1:1:1 to PBO, APR 20 mg BID (APR20), or APR 30 mg BID (APR30) stratified by baseline DMARD use (yes/no), and treated for 16 weeks to reach the primary end point. Patients completed the WLQ, a 25-item questionnaire that assesses the impact of chronic health conditions on work performance and productivity, at baseline and Week 16. Work limitations were categorized into 4 domains: physical demands (PDS), mental demands (MDS), time management demands (TMS), and output demands (ODS), which were then used to calculate the WLQ index. Results 504 patients were randomized in PALACE 1. Of the 261 patients who completed the WLQ, baseline work productivity and work limitations were similar across treatment groups. At Week 16, APR20 and APR30, vs. placebo, were associated with a greater mean change from baseline in PDS (-5.58 and -6.24 vs. -2.14), MDS (-2.22 and -5.18 vs. 1.15), TMS (-4.03 and -8.76 vs. -4.25), and ODS (-5.92 and -10.3 vs. -1.34), resulting in a greater mean improvement in the WLQ index (-0.01 and -0.03 vs. 0.00), which corresponds to a higher median percent improvement of productivity loss (18.9% and 24.7% vs. -3.7%). Higher productivity improvements were also observed among APR20 and APR30 ACR20 responders at Week 16 – PDS (-11.8 and -7.61), MDS (-8.56 and -11.0), TMS (-7.88 and -15.8), and ODS (-10.6 and -20.1) – resulting in a higher mean improvement in the WLQ index (-0.03 and -0.05), which corresponds to a higher median percent improvement in work productivity (57.9% and 46.8%). Conclusions APR20 and APR30 increased work productivity and improved work limitations compared with PBO in patients with active PsA despite prior conventional disease-modifying antirheumatic drugs (DMARDs) and/or biologics.
