Group Intervention Description Participants With Palmoplantar pustulosis (PPP) No intervention Participants treated with a new systemic therapy for their PPP, having had an inadequate response to a prior PPP therapy either as their first systemic therapy or as a switch from, or addition to, a previous systemic therapy will be observed. Participants will be treated in accordance with routine clinical practice in Japan in the outpatient specialist care setting. The primary data source for this study will be the medical records of each participant.
- Primary Outcome Measures
Name Time Method Percentage of participants who remain on their 'index systemic' therapy Up to 5 Years Percentage of participants who remain on their 'index systemic' therapy will be reported.
Percentage of Participants Ceasing Their 'Index Systemic' Therapy Up to 5 Years Percentage of participants ceasing their 'index systemic' therapy will be reported.
Time to Cessation of Index Systemic Therapy From Baseline Baseline, Up to 5 Years Time to cessation of index systemic therapy from baseline will be reported.
- Secondary Outcome Measures
Name Time Method Percentage of Participants Switching to a First Subsequent Systemic Therapy Within the Follow-up Period Every 6 Months Up to 5 Years Percentage of participants switching to a first subsequent systemic therapy within the follow-up period will be reported.
Percentage of Participants Adding a Concurrent Systemic Treatment to their 'Index Systemic' Therapy Baseline and Every 6 Months Up to 5 Years Percentage of participants adding a concurrent systemic treatment to their 'index systemic' therapy will be reported.
Percentage of Participants Receiving Each 'Index Systemic' Therapy Baseline Percentage of participants receiving each 'Index Systemic' therapy will be reported.
Percentage of Participants Changing the Dosage of their 'Index Systemic' Therapy Baseline and Every 6 Months Up to 5 Years Percentage of participants changing the dosage of their 'index systemic' therapy will be reported.
Time to Commencement of First Subsequent Systemic Therapy From Baseline Baseline and Every 6 Months Up to 5 Years Time to commencement of first subsequent systemic therapy from baseline will be reported.
Percentage of Participants Switching to a Second Subsequent Systemic Therapy Within the Follow-up Period Every 6 Months Up to 5 Years Percentage of participants switching to a second subsequent systemic therapy within the follow-up period will be reported.
Time to Commencement of Second Subsequent Systemic Therapy From Baseline Baseline and Every 6 Months Up to 5 Years Time to commencement of second subsequent systemic therapy from baseline will be reported.
Percentage of Participants Changing Their Concurrent Non-Systemic Therapy Within the Follow-up Period Every 6 Months Up to 5 Years Percentage of participants changing their concurrent non-systemic therapy within the follow-up period will be reported.
Mean and Distribution of Dermatology Life Quality Index (DLQI) Scores at Baseline Baseline Mean and distribution of DLQI scores at baseline will be reported. DLQI instrument consists of 10 questions covering six domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and bother with psoriasis treatment). The response options range from 0, not affected at all, to 3, very much affected. This gives an overall range of 0 to 30 where lower scores mean better quality of life.
Mean and Distribution of European Quality of Life (EuroQol) Group, 5-Dimension, 5-Level (EQ-5D-5L) Scores at Baseline Baseline Mean and distribution of EQ-5D-5L scores at baseline will be reported. EQ-5D-5L is a descriptive system of health-related quality of life states consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each of which can take one of five responses. The responses record five levels of severity (no problems/slight problems/moderate problems/severe problems/extreme problems) within a particular EQ-5D dimension. A lower score indicates worse health.
Mean and Distribution of Work Productivity and Activity Impairment: General Health (WPAI:GH) Scores at Baseline Baseline Mean and distribution of WPAI:GH scores at baseline will be reported. WPAI:GH questionnaire is a validated instrument to measure impairments in both paid work and unpaid work. It measures absenteeism, presenteeism as well as the impairments in unpaid activity because of health problem during the past seven days. It consists of 6-item questionnaire looks at the effect of health problems on ability to work and perform regular activities. The WPAI yields 4 types of scores: absenteeism (work time missed), presenteeism (impairment at work / reduced on-the-job effectiveness), work productivity loss (overall work impairment / absenteeism plus presenteeism) and activity impairment. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes.
Percentage of Participants with a Physician's Global Assessment (PGA) Score of 1 or Less (0 or 1) Baseline and Every 6 Months Up to 5 Years Percentage of participants with a PGA score of 1 or less (0 or 1) will be reported. The PGA is used to determine the participant's overall palmoplantar pustulosis lesions at a given time point. Overall lesions will be graded based on the scale where, 0 = clear;1 = almost clear; 2 = Mild; 3 = Moderate; 4 = Severe; 5 = Very severe.
Change From Baseline in PGA Score Baseline and Every 6 Months Up to 5 Years Change From baseline in PGA score will be reported. The PGA is used to determine the participant's overall palmoplantar pustulosis lesions at a given time point. Overall lesions will be graded based on the scale where, 0 = clear;1 = almost clear; 2 = Mild; 3 = Moderate; 4 = Severe; 5 = Very severe.
Change From Baseline in DLQI Score Baseline and Every 6 Months Up to 5 Years Change from baseline in DLQI score will be reported. DLQI instrument consists of 10 questions covering six domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and bother with psoriasis treatment). The response options range from 0, not affected at all, to 3, very much affected. This gives an overall range of 0 to 30 where lower scores mean better quality of life.
Change From Baseline in Pain Visual Analogue Scale (Pain-VAS) Score Baseline and Every 6 Months Up to 5 Years Change from baseline in Pain-VAS score will be reported. Pain-VAS is used to measure subjective pain status. It is a unilateral scale anchored at 0 (no pain) and 10 (worst pain imaginable).
Change in Primary Location of Pain Baseline and Every 6 Months Up to 5 Years Change in primary location of pain will be reported.
Change From Baseline in EQ5D-5L Index Score Baseline and Every 6 Months Up to 5 Years Change from baseline in EQ5D-5L index score will be reported. The EQ-5D-5L is a descriptive system of health-related quality of life states consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each of which can take one of five responses. The responses record five levels of severity (no problems/slight problems/moderate problems/severe problems/extreme problems) within a particular EQ-5D dimension.
Change from baseline in Work Productivity and Activity Impairment questionnaire (WPAI) Baseline and Every 6 Months Up to 5 Years Change from baseline in WPAI will be reported. WPAI questionnaire is a validated instrument to measure impairments in both paid work and unpaid work. It measures absenteeism, presenteeism as well as the impairments in unpaid activity because of health problem during the past seven days. The higher the score the greater impact on productivity.
Percentage of Participants with Adverse Events (AEs) and serious Adverse Events (SAEs) Up to 5 Years Percentage of participants with adverse events and serious Adverse Events will be reported. An adverse event is any untoward medical occurrence in a participant administered a medicinal (investigational or non-investigational) product. An adverse event does not necessarily have a causal relationship with the treatment. An adverse event can be any unfavorable and unintended sign (including an abnormal finding or lack of expected pharmacological action), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to that medicinal product.
