Cai et al. demonstrated that xeligekimab significantly improved the Psoriasis Area and Severity Index (PASI) scores in patients with moderate-to-severe plaque psoriasis, with 90.7% achieving PASI 75 at week 12. Xeligekimab was well-tolerated with no unexpected safety concerns.

The study assessed 420 Chinese patients, with 281 receiving xeligekimab and 139 on placebo. The study assessed PASI 75 and Physician Global Assessment (PGA) 0/1 at week 12, with sustained efficacy until week 52.
