June 4, 2018 updated by: Pfizer

Non-interventional Study Of The Effect Of Smoking Status Of The Patient On The Success Of Etanercept Therapy In Psoriasis

The main purpose of this study is to assess the effect of smoking status on the success of Etanercept therapy in patients with moderate-to-severe psoriasis.

Study Overview

Status

Completed

Detailed Description

Study hypothesis was based on the following rationale:

  • Psoriasis vulgaris is a chronic inflammatory skin disease with several extracutaneous manifestations and significant comorbidities (among others cardiovascular disease, metabolic syndrome, obesity and depression).
  • An increased prevalence of smoking among psoriasis patients, as compared with healthy subjects, has been observed in several studies
  • More recent studies suggest that cigarette smoking may trigger the development of psoriasis through oxidative, inflammatory and genetic mechanisms.Furthermore, smoking is associated with the clinical severity of psoriasis
  • Smoking also contributes to higher morbidity and mortality from smoking related disorders in these patients There is now some evidence that patients with psoriasis who smoke tend to be less responsive to treatment

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Group 1: smokers patients group
smokers (more than 10 cigarettes per day)

Data on smoking will include the age at which cigarette smoking began and ceased and the average amount smoked daily. Intensity (number of cigarettes smoked per day), duration of smoking (years), and time since cessation (years) will be categorized. Also, the smoking status of the patient prior psoriasis diagnosis will be assessed (smoker or non-smoker and years of smoking prior to psoriasis diagnosis).

Smoking habit evaluation: baseline and changes in smoking habit at 12 and 24-weeks follow-up time points.

Group 2 : non-smokers patients group
Smoking status will be classified as current and never/former. Former smokers will be defined as those who had stopped smoking at least 1 year before being interviewed for this study

Data on smoking will include the age at which cigarette smoking began and ceased and the average amount smoked daily. Intensity (number of cigarettes smoked per day), duration of smoking (years), and time since cessation (years) will be categorized. Also, the smoking status of the patient prior psoriasis diagnosis will be assessed (smoker or non-smoker and years of smoking prior to psoriasis diagnosis).

Smoking habit evaluation: baseline and changes in smoking habit at 12 and 24-weeks follow-up time points.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Psoriasis Assessment and Severity Index (PASI) Score at Week 24
Time Frame: Baseline, Week 24
PASI is the combined assessment of lesion severity and area affected into single score range: 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Body divided into 4 sections (head and neck [h], arms [u], trunk [t], legs [l]); each area scored by itself and scores combined for final PASI score. For each section, percent body surface area (A) of skin involved was estimated on a scale of 0 (no involvement) to 6 (90-100 percent involvement), severity was estimated by clinical signs: erythema (E), induration (I), scaling (S) on a 5 point scale: 0 (no involvement) to 4 (very marked involvement). Final PASI = sum of severity parameters for each section*area score*weighing factor (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4).
Baseline, Week 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Dermatology Life Quality Index (DLQI)
Time Frame: Baseline, Week 12, 24
The DLQI was a 10-item questionnaire that measures the impact of skin disease on participant's quality of life. Each question was evaluated on a 4-point scale ranging from 0 (not at all) to 3 (very much); where higher scores indicate more impact on quality of life. The DLQI total score ranges from 0 (not at all) to 30 (very much): 0-1 = no effect at all on the participant's life; 2-6 = small effect on the participant's life; 7-12 = moderate effect on the participant's life; 13-18 = very large effect on the participant's life; 19-30 = extremely large effect on the participant's life. Higher scores indicate more impact on quality of life of participants.
Baseline, Week 12, 24
Percentage of Participants With Psoriasis Area and Severity Index 75 (PASI75) Response at Week 12 and 24
Time Frame: Week 12, 24
PASI is the combined assessment of lesion severity and area affected into single score range: 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Body divided into 4 sections (head and neck [h], arms [u], trunk [t], legs [l]); each area scored by itself and scores combined for final PASI score. For each section, percent body surface area (A) of skin involved was estimated on a scale of 0 (no involvement) to 6 (90-100 percent involvement), severity was estimated by clinical signs: erythema (E), induration (I), scaling (S) on a 5 point scale: 0 (no involvement) to 4 (very marked involvement). Final PASI = sum of severity parameters for each section*area score*weighing factor (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4). PASI75 response was defined as at least a 75 percent (%) reduction in PASI relative to baseline.
Week 12, 24
Percentage of Participants With Psoriasis Area and Severity Index 50 (PASI50) Response at Week 12 and 24
Time Frame: Week 12, 24
PASI is the combined assessment of lesion severity and area affected into single score range: 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Body divided into 4 sections (head and neck [h], arms [u], trunk [t], legs [l]); each area scored by itself and scores combined for final PASI score. For each section, percent body surface area (A) of skin involved was estimated on a scale of 0 (no involvement) to 6 (90-100 percent involvement), severity was estimated by clinical signs: erythema (E), induration (I), scaling (S) on a 5 point scale: 0 (no involvement) to 4 (very marked involvement). Final PASI = sum of severity parameters for each section*area score*weighing factor (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4). PASI50 response was defined as at least a 50% reduction in PASI relative to baseline.
Week 12, 24
Change From Baseline in Psoriasis Assessment and Severity Index (PASI) Score at Week 12
Time Frame: Week 12
PASI is the combined assessment of lesion severity and area affected into single score range: 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Body divided into 4 sections (head and neck [h], arms [u], trunk [t], legs [l]); each area scored by itself and scores combined for final PASI score. For each section, percent body surface area (A) of skin involved was estimated on a scale of 0 (no involvement) to 6 (90-100 percent involvement), severity was estimated by clinical signs: erythema (E), induration (I), scaling (S) on a 5 point scale: 0 (no involvement) to 4 (very marked involvement). Final PASI = sum of severity parameters for each section*area score*weighing factor (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4).
Week 12
Change From Baseline in Psoriasis Assessment and Severity Index (PASI) Score in Obese Participants
Time Frame: Baseline, Week 12, 24
PASI is the combined assessment of lesion severity and area affected into single score range: 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Body divided into 4 sections (head and neck [h], arms [u], trunk [t], legs [l]); each area scored by itself and scores combined for final PASI score. For each section, percent body surface area (A) of skin involved was estimated on a scale of 0 (no involvement) to 6 (90-100 percent involvement), severity was estimated by clinical signs: erythema (E), induration (I), scaling (S) on a 5 point scale: 0 (no involvement) to 4 (very marked involvement). Final PASI = sum of severity parameters for each section*area score*weighing factor (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4). Participants who had bone marrow index >30 kilogram per meter square were said to be obese in this outcome measure.
