Persistence With Biologic Treatments in Psoriasis: A Structured Literature Review of Studies Using Administrative...

Psoriasis is a chronic, autoimmune-mediated inflammatory disorder. Drug persistence is a composite measure of effectiveness, safety, and treatment satisfaction, often estimated using data from administrative databases and clinical registries. Persistence rates calculated from these two data sources appear to be systematically different.

Review and compare persistence rates of psoriasis-indicated biologics reported in registry and database studies.

A structured literature search of studies published during 2009-2019 was performed in PubMed and American Academy of Dermatology records to identify research describing persistence with biologic treatments in psoriasis patients. English language retrospective or prospective persistence studies based on database or registry data, and reporting on at least two psoriasis-indicated biologics, of which at least one was ustekinumab, secukinumab, ixekizumab or guselkumab, were included. Single-arm studies, randomized control trials, systematic literature reviews, and studies presenting stratified results only were excluded.

A total of 37 studies (22 registry- and 15 database-derived) comprising 76,000 patients were included. On average, drug persistence collected from registry studies was 18% higher than database studies.

The findings of this study may be used by practitioners to make meaningful comparisons between persistence data derived from registries and databases, and thereby improve clinical decision making. J Drugs Dermatol. 2022;21(8):881-889. doi:10.36849/JDD.6789R1.
