Effects of Semaglutide on Clinical Outcomes and Metabolic Inflammation in Psoriasis

This study will evaluate the effects of oral semaglutide in combination with topical corticosteroid/calcipotriol on clinical outcomes and metabolic inflammation in patients with plaque psoriasis and overweight/obesity and/or type 2 diabetes mellitus. A total of 62 participants will be randomized to receive either semaglutide plus topical corticosteroid/calcipotriol or placebo plus topical corticosteroid/calcipotriol for 12 weeks.
