Study Evaluating the Safety and Effectiveness of Etanercept for the Treatment of Pediatric Psoriasis

Study Overview
=================
Brief Summary
-----------------
Psoriasis is a chronic, often severe, autoimmune condition that affects approximately 2% of the world's population. The epidemiology of pediatric psoriasis has not been well documented and no treatment guidelines exist for pediatric psoriasis. Etanercept is a biologic drug and has been licensed for the treatment of chronic severe plaque psoriasis in children and adolescents (6-17 years of age) who are inadequately controlled by or are intolerant to, other systemic therapies or phototherapies. Although the long-term safety and efficacy of etanercept in children with juvenile idiopathic arthritis (JIA) has been studied and the short-term safety profile of etanercept in both JIA and pediatric psoriasis appears similar, there is limited data available about the long-term effects of etanercept in pediatric psoriasis, especially with respect to malignancy. The aim of this study is to assess the safety and effectiveness of etanercept for the treatment of pediatric psoriasis in Europe. Patients aged <=17 with plaque psoriasis diagnosed by a dermatologist will be invited to participate in the registry only after a clinical decision has been made to prescribe etanercept. The safety of the drug and how well the drug works will be evaluated during the follow-up period. The follow-up period will last 5 years and patients will be followed up every 3 months for the first 2 years and every 6 months for the next 3 years or until the end of study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Serious Infections, Opportunistic Infections of Interest and Malignancies: Prospective Participants | Serious infections were defined as any infections those were life-threatening or resulted in disability, infections requiring intravenous antibiotic treatment and hospitalisation. Opportunistic infections of interest included protocol-specified infections due to bacteria: Salmonella bacteremia, Campylobacteriosis, Shigellosis, Mycobacterium tuberculosis, Mycobacterium avium, Mycobacterium kansasii, Syphilis, Pseudomonas aeruginosa, Acinetobacter baumannii, Listeriosis, Nocardiosis, Legionellosis, Actinomycosis, Bartonellosis; Fungal: Aspergillosis, Invasive Candida albicans, Coccidioidomycosis, Cryptococcosis, Histoplasmosis, Blastomycosis, Paracoccidioidomycosis, Sporotrichosis, Penicilliosis, Zygomycosis and Pneumocystosis; Protozoans: Cryptosporidiosis, Isosporiasis, Microsporidiosis, Acanthamoebiasis, Toxoplasmosis, Trypanosomiasis and Leishmaniasis; Viral: Cytomegalovirus, John Cunningham Virus, Disseminated or central nervous system herpes zoster, Kaposi's sarcoma and BK virus. | Baseline up to 5 years | 
| Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs): Prospective Participants | An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. AEs included both serious and non-serious adverse events. | Baseline up to 28 days after last dose of study drug (up to 61 months) | 
| Number of Participants Who Discontinued From Etanercept During Initial Treatment Period: Prospective Participants | Initial treatment period is defined as the period during which participants received Etanercept treatment for a duration of at least 24 weeks. | Baseline up to 24 weeks | 
| Number of Participants Who Discontinued From Etanercept After Initial Treatment Period: Prospective Participants | Initial treatment period is defined as the period during which participants received Etanercept treatment for a duration of at least 24 weeks. | Week 24 up to Week 216 | 
| Percentage of Participants Who Required Subsequent Treatment With Etanercept or Other Systemic Therapies After Completion of Initial Treatment Period: Prospective Participants | Participants those who completed the initial treatment period of at least 24 weeks and entered the follow up period, and during the follow up period who required subsequent treatment with etanercept or other systemic therapies were reported. | Week 24 up to Week 216 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Duration of Subsequent Etanercept Treatment After Completion of Initial Treatment Period |  | Week 24 up to Week 216 |
