A Study to Assess Benefits of Apremilast in Patients With Moderate to Severe Chronic Plaque Psoriasis Followed by Dermatologists Under Real Life Settings in France

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.
