Proportions of Biologic Discontinuation Among Psoriasis Patients With Metabolic Comorbidities

Abstract

Background

Among psoriasis patients, the presence of metabolic comorbidities associates with poorer response to biologics. How the presence of comorbidity impacts treatment patterns with biologics is not fully understood.

Methods

Adult patients in the CorEvitas Psoriasis Registry were included if they initiated biologic therapy between 5/2015–12/2019 and had a 6-month follow-up visit. The frequency of biologic discontinuations by 6-months were calculated by metabolic comorbidity status (current obesity and histories of hypertension [HTN], diabetes [DM], and hyperlipidemia [HLD]) for all patients and by drug class (tumor necrosis factor inhibitors [TNFi], interleukin-17i [IL-17i], and IL-23i or IL-12/23i).

Results

Among the 2924 participants, discontinuations were more frequent in those with obesity (17%, P < .01) or DM (20%, P < .001) compared to those without these (13% and 14%, respectively). Discontinuations were similar for those with and without histories of HTN or HLD. Frequencies of discontinuation for each biologic class were: TNFi (26%), IL-17i (16%), and IL-23i or IL-12/23i (9%). Among TNFi initiators, the proportions of discontinuations were greater in the presence of obesity (30%, P < .05), DM (34%, P < .05), or HTN (34%, P < .01) compared to those without (22%, 24%, and 22%, respectively). Of the IL-23i or IL-12/23i initiators, discontinuations were more frequent in those with obesity (11%, P < .01) or with DM (13%, P < .05) compared to those without (7% and 8%, respectively). Discontinuations did not statistically differ between comorbidity groups in IL-17i initiators.

Conclusion

Comorbid disease status, especially obesity and DM, should be assessed at biologic initiation as it may predict a less optimal clinical outcome.
