1. Study identification
EU PAS Register NumberEUPAS28457
Official titleAn Observational Post-Authorisation Safety Study of Skilarence in European Psoriasis Registers
Study title acronym
Study typeObservational study
Brief description of the studyPsoriasis is a chronic inflammatory skin disorder that results from complex interactions between genes, the immune system, and environmental factors, although the exact cause remains unclear. Skilarence (dimethyl fumarate; DMF) received European marketing authorisation for the treatment of moderate to severe chronic plaque psoriasis in adult patients on 23 June 2017.
This study aims to evaluate the long-term safety of Skilarence used for the treatment of patients with moderate to severe psoriasis. The study will evaluate whether the use of Skilarence is associated with an increased risk of serious infections (including serious opportunistic infections such as progressive multifocal leukoencephalopathy), malignancies, or renal impairment as compared with conventional (non-biologic) systemic therapies. In addition, the study aims to describe the use of Skilarence in patient subgroups for which there is missing information.
The study is a long-term, non-interventional, observational post-authorisation safety study that will use a prospective cohort design, and data from established registers of patients with psoriasis treated with systemic therapies in Germany, Spain, and the UK and Republic of Ireland.

11. Scope of the study
What is the scope of the study?
Risk assessment
Drug utilisation study
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
The primary objectives are to evaluate the risk of serious infections, malignancies, and renal impairment in new users of Skilarence compared with new users of conventional systemic therapies and to describe the characteristics of users of Skilarence and users of conventitional systemic therapies.
Are there primary outcomes?Yes
- All serious infections
- Serious opportunistic infections (including progressive multifocal leukoencephalopathy)
- All malignancies
- All renal impairments, including Fanconi syndrome
Are there secondary outcomes?Yes
- All “other” SAEs by MedDRA System Organ Class
- All AEs by MedDRA System Organ Class
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Patients will be followed from cohort entry through the end of study period (31 December 2026). The date of end of follow-up will be defined as the date of the earliest of the following events: exiting the register, death, end of study period or any of the censoring events. Follow-up of patients is expected to range from 2 months to 9 years, depending on the date of cohort entry.
15. Data analysis plan
Please provide a brief summary of the analysis method
Annual analyses based on standard periodic analyses conducted by each register, describing:
-Cohorts at baseline using mean values and standard deviations for continuous variables and percentages for categorical variables
-Treatment course, including number of patients and cumulative person-time in each cohort, proportion of treatment discontinuations and reasons for discontinuation
-Safety endpoints
-All “other” SAEs and AEs
Final analyses, at end of study period:
-Incidence rates for patients initiating Skilarence and for patients initiating other conventional systemic therapies will be estimated overall and stratified by relevant baseline factors
-Crude, stratified, and adjusted incidence rates ratio estimates comparing Skilarence and other conventional systemic therapies
-Point estimates from pooled analysis of estimates from the three registers: incidence rates, overall and stratified by selected factors, and IRRs adjusted for relevant factors
