Generalized Pustular Psoriasis

Prospective, observational registry for subjects with GPP under the care of a dermatology investigator.Approximately 200 subjects and 75 clinical sites in North America will be recruited to participate with no defined upper limit for either target

The goal of this observational registry study is to characterize the clinical, epidemiological, and therapeutic features of patients with generalized pustular psoriasis (GPP) in Costa Rica through a standardized national registry. The main question it aims to answer is: What are the clinical, epidemiological, and therapeutic characteristics of patients with generalized pustular psoriasis registered in the country, and how do these relate to disease severity and evolution? Patients with GPP receiving routine dermatologic care in participating centers will have their demographic, clinical, severity, comorbidity, and treatment data recorded using a standardized case report form. Clinical assessments (e.g., GPPASI, PASI/BSA, DLQI), laboratory results, triggers, complications, and therapies will be documented and updated during periodic follow-up visits as part of usual care.

This is a Phase IIb, long term extension study to evaluate the safety and efficacy of HB0034 in adult subjects with generalized pustular psoriasis (GPP).
