Secukinumab Drug Survival, Effectiveness and Tolerability in Pediatric Patients With Psoriasis

Study Overview
=================
Brief Summary
-----------------
Multicenter, non-interventional, cohort study in pediatric patients with moderate to severe plaque-type psoriasis. Retrospective data collection is planned at patients' inclusion.

Detailed Description
-----------------
This observational study will be performed at healthcare facilities treating pediatric psoriasis patients. The study population will consist of a representative group of pediatric patients with moderate-to-severe plaque psoriasis for whom routine treatment with secukinumab according to the approved national label is initiated during 4 to 16 weeks Retrospective data collection is planned at patients' inclusion. Prospective data collection will continue during follow-up routine visits until secukinumab discontinuation or maximum duration of follow-up for 104 weeks after index date.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Written informed consent and legal representative's permission for study participation obtained prior to beginning of participation in the study. Age ≥6 to <18 years old. Established diagnosis of active moderate-to-severe plaque psoriasis defined as a PASI score ≥ 10, body surface area (BSA) involvement of ≥10% and PGA score ≥ 3 only or with concomitant psoriatic arthritis. Failure or intolerance of prior psoriasis treatment. Patient was prescribed with secukinumab within 4-16 weeks before inclusion. Decision for secukinumab prescription was made by the attending physician according to the approved national label during routine clinical practice, regardless of this non-interventional study conduct. Exclusion Criteria: Known or suspected severe hypersensitivity for secukinumab, formulation excipients, or injection device components (i.e., latex). History of chronic recurrent infection. Clinically significant infection exacerbation, including active tuberculosis. Age <6 years or ≥18 years. Pregnancy and breastfeeding. Patients participating in parallel in an interventional clinical trial. Patients participating in parallel in other Novartis-sponsored non-interventional study generating primary data for secukinumab. Patients within the safety follow-up phase of interventional study. Active inflammatory bowel disease at inclusion. Patients who received any vaccine within 4 weeks prior to secukinumab initiation. Any medical or psychological condition in the investigator's opinion which may prevent the study participation.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Drug survival rate of secukinumab | Drug survival is defined as time from the index date (defined as secukinumab treatment initiation) until discontinuation of secukinumab (defined as ≥2 missed consecutive doses with drug discontinuation proved by investigator in eCRF). | 52 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of patients discontinued secukinumab by reason | Proportion of patients discontinued secukinumab by reason: Lack of efficacy Adverse events Administrative reasons (no medication available in the hospital, etc.) Lack of patient's adherence Patient's or legal representative's wish Other | Week 12, week 24, week 52 and week 104 | 
| Drug survival rate | Drug survival is defined as time from the index date (defined as secukinumab treatment initiation) until discontinuation of secukinumab (defined as ≥2 missed consecutive doses with drug discontinuation proved by investigator in eCRF). | 104 weeks | 
| Secukinumab survival rates | Secukinumab survival rate is defined as proportion of patients who have not discontinued treatment due to reasons other than lack of efficacy. | Week 24, week 52, and week 104 after the index date | 
| Time to treatment discontinuation due to ineffectiveness | Time from index date to treatment discontinuation due to ineffectiveness | Week 12, week 24, week 52, week 104 | 
| Proportion of patients achieving PASI 75 responses | Psoriasis Area and Severity Index (PASI) takes into account the extent of the disease, as well as the severity of erythema, scaling, and thickness in different body areas affected by psoriasis. A PASI 75 represents an improvement in the PASI score of at least 75% as compared with baseline. | Baseline (study inclusion), week 24, week 52, and week 104 after the index date | 
| Proportion of patients achieving PASI 90 responses | Psoriasis Area and Severity Index (PASI) takes into account the extent of the disease, as well as the severity of erythema, scaling, and thickness in different body areas affected by psoriasis. A PASI 90 represents an improvement in the PASI score of at least 90% as compared with baseline. | Baseline (study inclusion), week 24, week 52, and week 104 after the index date | 
| Proportion of patients achieving PASI 100 responses | Psoriasis Area and Severity Index (PASI) takes into account the extent of the disease, as well as the severity of erythema, scaling, and thickness in different body areas affected by psoriasis. A PASI 100 response corresponds to complete clearing of psoriasis (PASI = 0). | Baseline (study inclusion), week 24, week 52, and week 104 after the index date | 
| Proportion of patients achieving a physicians' global assessment (PGA) 0/1 response | Proportion of patients achieving a physicians' global assessment 0/1 response: clear/almost clear skin | Baseline (study inclusion), week 24, week 52, and week 104 after the index date | 
| Adverse events (AEs) of special interest | Adverse events (AEs) of special interest: Inflammatory Bowel Disease, malignancy, tuberculosis, serious infections, candidiasis, acute injection site reaction, immunogenicity | Week 12, week 24, week 52, week 104 after the index date |
