Effects of Semaglutide on Clinical Outcomes and Metabolic Inflammation in Psoriasis: A Randomized, Triple-Blind, Placebo-Controlled Clinical Trial

Обзор

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. Clinical efficacy will be assessed using the Psoriasis Area and Severity Index (PASI), and quality of life will be evaluated using DLQI, PROMIS-29, and EQ-5D-5L. Systemic inflammatory markers will also be measured to assess metabolic inflammation.

Подробное описание

Psoriasis is a chronic inflammatory skin disease frequently associated with metabolic comorbidities, including obesity and type 2 diabetes mellitus. Increasing evidence suggests that systemic metabolic inflammation may contribute to psoriasis severity and treatment response. Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist widely used in the management of type 2 diabetes and obesity, has demonstrated anti-inflammatory effects that may be relevant to psoriasis.

This study is a randomized, triple-blind, placebo-controlled clinical trial designed to evaluate the effects of oral semaglutide on clinical disease activity, quality of life, and metabolic inflammatory markers in patients with plaque psoriasis and overweight/obesity and/or type 2 diabetes mellitus.

A total of 62 participants will be enrolled and randomized in a 1:1 ratio to one of two treatment groups. One group will receive oral semaglutide in combination with topical corticosteroid/calcipotriol cream, while the comparator group will receive oral placebo in combination with topical corticosteroid/calcipotriol cream. All participants will receive treatment for 12 weeks.

Clinical assessments will be performed at baseline and at weeks 4, 8, and 12. Disease severity and clinical response will be evaluated using the Psoriasis Area and Severity Index (PASI) at each visit. Patient-reported quality of life will be assessed using the Dermatology Life Quality Index (DLQI), the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29), and the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) at baseline and at week 12.

Blood samples will be collected at baseline and at week 12 to evaluate systemic inflammatory and metabolic biomarkers, allowing assessment of changes in metabolic inflammation associated with treatment.

The primary hypothesis is that participants receiving semaglutide in combination with topical corticosteroid/calcipotriol will demonstrate greater improvement in clinical severity and inflammatory markers compared with those receiving placebo plus topical corticosteroid/calcipotriol. Findings from this study may provide evidence supporting the role of metabolic-targeted therapies as adjunctive treatment in psoriasis patients with metabolic comorbidities.

Вмешательства

• Препарат Semaglutide (Rybelsus®)
  Oral semaglutide will be administered once daily at a dose of 3 mg for the first 4 weeks, followed by 7 mg once daily for the next 4 weeks, and 14 mg once daily for the final 4 weeks (total treatment duration: 12 weeks). All participants will also receive conventional topical therapy for 12 weeks, consisting of a topical corticosteroid and a vitamin D analog (calcipotriol).
• Препарат Placebo
  A total of 31 participants will be randomly assigned to the placebo intervention group. They will receive a daily placebo tablet containing starch for 12 weeks. All participants will also receive conventional topical therapy for 12 weeks, consisting of a topical corticosteroid and a vitamin D analog (calcipotriol).
