ABSTRACT
BACKGROUND AND OBJECTIVE:
Data on real-world healthcare costs for ixekizumab (IXE) and secukinumab (SEC) in biologic-experienced patients with psoriasis are limited. This study compared real-world costs and healthcare resource utilization between IXE and SEC in biologic-experienced patients with psoriasis over an 18-month follow-up period in the USA.METHODS:
Adult patients with a diagnosis of psoriasis between 1 March, 2015 and 31 October, 2019 were identified using health insurance claims data from IBM Watson Health MarketScan®. The index date was the date of the first IXE or SEC claim. Biologic-experienced patients with one or more pre-period claims for biologic drugs were identified. Inverse probability of treatment weighting was used to reduce cohort imbalances. All-cause and psoriasis-related direct healthcare costs along with index drug costs were estimated during the follow-up and reported as per patient per month. Discount factors published by the Institute for Clinical and Economic Review were applied to psoriasis-related biologics to adjust pharmacy costs.RESULTS:
A total of 411 IXE and 780 SEC users were included. After weighting, all-cause inpatient admissions were similar between IXE (9.5%) and SEC users (10.3%). Weighted, mean ± standard deviation per patient per month all-cause healthcare costs were higher in IXE users ($6670 ± $2910) than in SEC users ($6239 ± $3903; p = 0.049). Psoriasis-related and monthly index drug costs were higher in IXE users ($5609 ± $2009; p < 0.001 and $4688 ± $1994; p < 0.001, respectively) than in SEC users ($5095 ± $2291 and $3853 ± $1977, respectively). After Institute for Clinical and Economic Review adjustment, mean per patient per month all-cause ($4363 ± $2576 vs $4398 ± $3517) and psoriasis-related costs ($3302 ± $1264 vs $3253 ± $1504) were similar between the groups. Institute for Clinical and Economic Review- and adherence-adjusted mean per patient per month index drug costs were similar between IXE and SEC users (p = 0.339).CONCLUSIONS:
Institute for Clinical and Economic Review-adjusted all-cause and psoriasis-related costs were comparable between IXE and SEC users among biologic-experienced patients over an 18-month follow-up period.
