Abstract
INTRODUCTION: Associations between increased functional disability and higher healthcare resource utilization (HCRU) and costs were reported in patients with psoriatic arthritis (PsA). We assessed characteristics/outcomes of patients with PsA receiving tofacitinib monotherapy vs combination therapy with conventional synthetic disease-modifying antirheumatic drugs.
METHODS: Claims data from Optum
RESULTS: This analysis included 274 and 395 tofacitinib-treated patients in OC (70.4% female, mean age 54.4 years) and MS (68.9% female, mean age 51.4 years), respectively. Percentages of patients with a proportion of days covered ≥ 0.8 at 12 months for monotherapy vs combination therapy were OC, 44.5% vs 53.8%; MS, 36.4% vs 45.7%. Generally similar trends were seen over 24 months and for medication possession ratio ≥ 0.8. Median (95% confidence interval) times to treatment discontinuation for monotherapy vs combination therapy were OC, 10.1 (7.4-11.8) vs 16.7 (8.3-26.6) months; MS, 6.9 (5.6-9.4) vs 11.0 (6.1-13.9) months. During off-treatment vs on-treatment periods, numerical decreases were observed for all-cause (OC, $5383 vs $6149; MS, $4145 vs $5180) and PsA-related costs (OC, $3237 vs $4515; MS, $2703 vs $3907) regardless of therapy type. During off-treatment vs on-treatment periods, numerical increases in outpatient visits for all-cause (OC, 2.37 vs 2.05; MS, 2.15 vs 1.99) and PsA-related visits (OC, 0.60 vs 0.46; MS, 0.47 vs 0.44) were observed, and PsA-related medications numerically decreased (OC, 1.21 vs 1.53; MS, 1.05 vs 1.48).
CONCLUSION: In this USA-based claims analysis, tofacitinib adherence was numerically lower for patients with PsA receiving monotherapy vs combination therapy. Costs numerically decreased off-treatment vs on-treatment, irrespective of therapy type, driven by lower medication costs.
