Characteristics of Patients Treated With Secukinumab for Moderate to Severe Plaque Psoriasis

The Characteristics of Patients Treated With Secukinumab for Moderate to Severe Plaque Psoriasis in Real-world Practice in Thailand

This study was a non-interventional, retrospective study collecting data from hospital medical records. Approximately 200 adult patients with moderate to severe plaque psoriasis who were treated with secukinumab from hospitals in Thailand that participated in this study were expected for data collection.

Study Overview

• Status: Completed
• Conditions: Plaque Psoriasis
• Intervention / Treatment: Drug: Secukinumab

Detailed Description

The study was performed in 7 study sites in Thailand and planned to involve approximately 200 medical records.

At each study site, patients who were treated with secukinumab or had ever been treated with secukinumab for moderate to severe plaque psoriasis were included for screening by chronological order starting from the most recent date (April 2021) to September 2017. This was to include the most recent clinical practice in the study.

The data of patients diagnosed with moderate-to-severe chronic plaque-type psoriasis who received secukinumab in real clinical practice at least 1 dose were collected. The medical records were reviewed to collect the data from the date of the first diagnosis of psoriasis till the most recent dose of secukinumab.

The data of secukinumab use and clinical outcome (PASI score) were collected at 4 and 16 weeks after first dose initiation and at the most recent dose of secukinumab. The total number of secukinumab injections at the 3-time points were collected.

An index date was defined for each patient. The first secukinumab injection observed in the medical records was considered the index date for the exploratory endpoint.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Age	Age information was reported.	Baseline
Gender	Gender information was reported.	Baseline
Number of patients with Reimbursement scheme	Reimbursement scheme information was reported.	Baseline
Weight	Weight information was reported.	During 3 months pre-baseline
Height	Height information was reported.	During 3 months pre-baseline
BMI	BMI information was reported.	During 3 months pre-baseline
Co-morbidities	Crohn's Disease; Diabetes Mellitus; Dyslipidemia; Hypertension; Inflammatory Bowel Disease; Latent Tuberculosis; Psoriatic Arthritis (PsA)	During 12 months pre-baseline
Psoriasis Area and Sensitivity Index (PASI) score	Psoriasis Area and Severity Index (PASI) is the most widely used tool for the measurement of severity of psoriasis. PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease).	During 4 weeks pre-baseline
Percentage of Body Surface Area (BSA) involvement	Percentage of Body Surface Area (BSA) involvement was reported.	During 4 weeks pre-baseline
Disease Life Quality Index (DLQI) score	The Dermatology Life Quality Index (DLQI) is a simple, self-administered and user-friendly validated questionnaire. The DLQI is designed to measure the health-related quality of life of adult patients suffering from a skin disease. The DLQI is a validated, 10-question, self-reported questionnaire to evaluate the patient's perception of the impact of psoriasis on quality of life. The DLQI was rated on a 4-point scale (0 = not at all to 3 = very much). The highest possible total score for the DLQI is 30 and higher scores indicate more severe impact on quality of life.	During 4 weeks pre-baseline
Date of first symptom of psoriasis (PSO) / year	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Date of psoriasis diagnosis / year	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Duration of psoriasis diagnosis	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Date of first systemic treatment/ year	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Date of first biologic agent/year	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Duration of topical therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
History of topical therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Duration of systemic therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
History of systemic therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Duration of biologic therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
History of biologic therapy	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
Date of PsA diagnosis/year	To describe the PSO treatment history	Approximately 2 years pre-baseline (PSO diagnosed date to index date, where index date is defined as date of initiation of treatment)
