| Summary: | Abstract Introduction Psoriasis is a chronic immune-mediated disease with significant systemic implications. Tildrakizumab, an IL-23p19 inhibitor, has demonstrated efficacy in moderate-to-severe plaque psoriasis. Higher doses may be beneficial for patients with elevated body weight or greater disease burden. This study evaluates the effectiveness of tildrakizumab 200 mg in a real-world setting, analyzing outcomes based on weight, Psoriasis Area Severity Index (PASI), body mass index (BMI), and prior biologic exposure. Methods A multicenter retrospective study was conducted across 10 Italian hospitals. Adult patients (≥ 18 years) with moderate-to-severe plaque psoriasis treated with tildrakizumab 200 mg for ≥ 36 weeks were included. Patients were stratified by weight (≥ 90 kg vs. < 90 kg), BMI (≥ 30 vs. < 30), PASI (≥ 15 vs. < 15), and biologic history (naïve vs. biologic (bio)-experienced). PASI100 response rates at 36 weeks were assessed. Statistical analyses included Fisher’s exact test (p < 0.05 significant). Results Among 137 patients, PASI100 response rates were 67.1% for patients < 90 kg vs. 49.2% for ≥ 90 kg (p = 0.04), 61.5% for PASI < 15 vs. 50% for PASI ≥ 15 (p = 0.03), and 60.8% for bio-naïve vs. 57.1% for bio-experienced (p = 0.08). BMI ≥ 30 was associated with lower PASI100 (44.2%) compared to BMI < 30 (61.4%) (p = 0.05). Despite subgroup differences, all patients exhibited clinical improvement. Conclusion Tildrakizumab 200 mg effectively treated moderate-to-severe psoriasis across diverse patient subgroups. While higher weight and PASI were associated with slightly lower PASI100 rates, significant improvements were observed, supporting its role in difficult-to-treat patients. |
