REALIZE study will include a representative sample of 500 patients with moderate to severe plaque psoriasis for whom the treating dermatologist has decided to begin apremilast treatment in accordance with the local label reimbursement criteria. Patients may be enrolled into the study up to 4 weeks after starting the study treatment. REALIZE is a longitudinal, multicenter, observational study under real life settings in patients with moderate to severe chronic plaque psoriasis after failure or contra-indication or intolerance to other systemic therapy including ciclosporin, methotrexate, or phototherapy UVA + psoralen (PUVA therapy).
Eligible patients will be identified and invited to enroll from approximately 100 dermatologists in France practicing in public hospitals (or private clinics) or private practice. Patients will be followed over 12 months after initiation of apremilast or until discontinuation of apremilast whatever the earlier. Given the observational nature of the study, apremilast dosing and duration will be at the sole discretion of the treating dermatologist, in accordance with the local label and daily clinical practice. Patient care will follow routine clinical practice, involving regular follow-up visits, without any mandatory visit. In daily practice, patients are usually seen by their treating dermatologist every 6 months. In this study, patients will be followed up at most 12 months after apremilast initiation. During this study, it is expected to collect data at inclusion (enrolment visit) and around 6 months and 12 months after apremilast initiation, on electronic case report forms (eCRF) by the dermatologist after performing a visit around 6 and 12 months to evaluate the treatment response following the apremilast initiation. Due to the observational nature of the study, the study protocol does not require any specific tests or additional examinations. All assessments will be recorded in the electronic case report form (eCRF) according to the normal practice of the treating dermatologist. Self-questionnaires will be filled by the patient when visiting his/her dermatologist. Total duration of the study is 2 years and 6 months, which includes an enrollment period of 1 year and 6 months and a follow up period of up to 1 year.

Adherence Rate
The adherence rate will be defined as the percentage of patients pursuing the treatment with apremilast at 12 months after the initiation of apremilast.. The calculation will take into account the patients having started and discontinued apremilast within 4 weeks before the enrolment visit.
Time frame: Up to 12 months

The percentage of patients substituting apremilast by a biologic will be estimated by the Kaplan Meier method. The date of origin will be defined as the date apremilast has been started.
Time frame: Up to 24 months
Dermatology Life Quality Index (DLQI)
DLQ is a 10-item validated questionnaire used in a wide range of dermatological conditions and across a wide range of disease severity as a quality of life instrument. It covers a variety of health dimensions, including symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment. The recall period is 7 days. Each item is graded on a Likert scale of 0-3, which gives an overall score ranging from 0 to 30 where lower scores mean better quality of life.
Time frame: Up to 24 months
