Overview

Palmoplantar pustulosis (PPP) is a chronic and recurrent skin disease, mainly characterized by erythema, pustules and scales on the palms and soles, often accompanied by itching and pain, which seriously affects the quality of life of patients. Currently, the treatment options for PPP are limited. Traditional therapies such as topical glucocorticoids, phototherapy and oral immunosuppressants have unsatisfactory efficacy, and long-term use may cause significant side effects. The introduction of biologics has provided a new direction for the treatment of PPP, but targeted therapy research for PPP is still scarce, and there are unmet clinical needs. The exploratory study of Xeligekimab in PPP is expected to provide a new treatment option, alleviate symptoms and improve the quality of life of patients. This study takes the domestic Xeligekimab as the research object, aiming to verify its potential in PPP and contribute to the breakthrough of domestic biologics in the field of refractory skin diseases. If the study is successful, it can provide preliminary evidence support for the addition of PPP as an indication for Xeligekimab and offer a preliminary theoretical basis for adding a new option to targeted therapy for PPP.

Interventions

  • Drug Xeligekimab Injection
    Administration plan: Induction period (0-4 weeks): 200 mg (2 vials of 100 mg), administered subcutaneously every 2 weeks (at weeks 0, 2, and 4, Q2W) Maintenance period (8-20 weeks): 200 mg, administered subcutaneously every 4 weeks (at weeks 8, 12, 16, and 20, Q4W). Administration site: The abdomen is the preferred site, with the upper arm or thigh as alternative options. Before injection, check that the skin is free from infection or damage. The procedure should be performed under sterile con
