Abstract
INTRODUCTION
Prior studies have demonstrated guselkumab improves disease activity and patient-reported outcomes (PROs) among patients with moderate-to-severe plaque psoriasis. However, the real-world effectiveness of guselkumab across different subgroups [e.g., body mass index (BMI) categories] remains an area of active research.
METHODS
This study included patients enrolled in the CorEvitas Psoriasis Registry between July 18, 2017 and March 10, 2020 who had moderate-to-severe psoriasis [Investigator's Global Assessment (IGA) score ≥ 3], initiated guselkumab at a registry visit (index date), and had a follow-up registry visit after persistent guselkumab therapy for 9-12 months. Patients were stratified into three BMI categories: obese (≥ 30 kg/m2), overweight (25- < 30 kg/m2), and underweight/normal weight (< 25 kg/m2). Response rates and mean changes for disease activity outcomes and PROs at follow-up were assessed within each BMI category.
RESULTS
Of the 180 patients included in the study, 101 (56%) were obese, 52 (29%) were overweight, and 27 (15%) were underweight/normal weight. Among the obese, overweight, and underweight/normal weight patients, 57%, 58%, and 72%, respectively, achieved an IGA score of 0/1 after 9-12 months of persistent guselkumab treatment. An IGA score of 0 was achieved by 33%, 35%, and 48% of obese, overweight, and underweight/normal weight patients, respectively. A 90% improvement in the Psoriasis Area and Severity Index was achieved by 46%, 46%, and 56% in these respective subgroups. Mean improvements in disease activity and PRO scores were similar among BMI subgroups.
CONCLUSION
The results of this real-world study showed improvements in disease severity and several PRO scores within all BMI categories among patients with moderate-to-severe psoriasis treated with guselkumab. These unadjusted findings suggest that obese and overweight patients have comparable absolute improvements to those with lower BMI; however, they may be less likely to achieve relative endpoints. Additional analyses are needed to fully characterize this relationship.
