Study to Evaluate the Benefits for the Patient Associated With the Treatment of Plaque Psoriasis With Apremilast After Other Systemic Treatment in Conditions of Clinical Practice in Spain

Observational, prospective and multicenter study in approximately 30 sites nationwide. The investigators participating in this study will be dermatologists specializing in this pathology. The present study will include adult patients with moderate to severe plaque who have started apremilast treatment for first time 3 months (+/- 4 weeks) before their inclusion in the study, according to the specifications of the drug's prescribing information and under usual clinical practice. Recruitment will be consecutive and the reason for not including a potential candidate patient will be registered. The decision to prescribe apremilast treatment should be clearly dissociated from the inclusion of the patient in the study. Therefore, the choice of the therapeutic strategy will be made independently by the physician.
