About this study
Official title: CARE: A CAnadian Real World Evidence Study of Brodalumab in Plaque Psoriasis to Understand the Impact on Quality of Life and Work Productivity
This is a phase IV, 12-month observational, prospective, open-label, multi-center study that will be conducted across approximately 50 sites in Canada for an estimated study duration of 32 months. All eligible adult participants who are enrolling into the SILIQ Patient Support Program (PSP) and initiating brodalumab as per routine care may be offered participation in the study. If the participant agrees, their verbal consent and details will be entered into the study platform by the enrolling physician so that the participant can access the electronic informed consent form. Participants who meet the eligibility criteria and provide electronic informed consent will be enrolled in the study. The study observation period will be 12 months (±15 days). Data will be collected on approximately 500 participants across academic and community centers.

What is being measured
The primary outcome is the main question the study is designed to answer.
The percentage change from baseline of the Dermatology Life Quality Index (DLQI) at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Dermatology Life Quality Index (DLQI) measure is self administered and includes domains of daily activities, leisure, personal relationships, symptoms and feelings, treatment, and work/school. Each item has four response categories, ranging from 0 (not at all or not relevant) to 3 (very much) assessing the impact of the disease over the last week. The DLQI total score is a sum of the 10 questions. Scores range from 0 to 30 and higher scores indicate greater health-related quality-of-life impairment.
Measured: baseline, 3 months, 6 months, 12 months
The percentage change from baseline of the Work Productivity and Activity Impairment: Psoriasis (WPAI:PSO) component scores at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Work Productivity and Activity Impairment: Psoriasis (WPAI:PSO) is a validated self-reported 6-item questionnaire that allows quantitative assessment of the effects of PsO on work productivity, daily activities, and classroom impairment. Scores are calculated as percentages of hours worked and percentages of productivity at work on workdays for respondents who are employed at the time of questionnaire completion.
Measured: baseline, 3 months, 6 months, 12 months
The percentage change from baseline of the Health Utility Index (HUI2) at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Health Utility Index (HUI2) is a 15-item questionnaire that allows researchers to classify the health status of patients and consists of seven attributes (sensation, mobility, emotion, cognition, self-care, pain, and fertility). Health state levels for descriptive responses are converted to health utilities scores using single- and multi-attribute utility functions that consist of look-up tables and mathematical formulae. Utility values for HUI2 range from -0.03 to 1.00, where a value of 1.00 indicates perfect health and a score of 0.00 corresponds to death. Negative scores represent health states considered to be worse than death.
Measured: baseline, 3 months, 6 months, 12 months
The mean Treatment Satisfaction Questionnaire for Medication (TSQM) domain scores at baseline, 3 months, 6 months, and 12 months post-brodalumab initiation.
The self-administered Treatment Satisfaction Questionnaire for Medication (TSQM) questionnaire is along 4 dimensions: medication effectiveness, side effects of use, convenience of use, and global/overall satisfaction. The scale for TSQM scores ranges from 0 (extremely dissatisfied) to 100 (extremely satisfied).
Measured: baseline, 3 months, 6 months, 12 months
Secondary outcomes (25)
The number and percentage of patients on brodalumab at baseline, 3 months, 6 months, and 12 months post-initiation by key patient demographics and clinical characteristics.
Key demographics and clinical characteristics include: prior biologic experience, age, gender, province, disease duration, number of comorbidities.
Measured: baseline, 3 months, 6 months, 12 months
The number and percentage of patients that initiated brodalumab achieving a Psoriasis Area Severity Index (PASI) response of 75, 90 or 100 at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Psoriasis Area Severity Index (PASI) score (0 to 72) is a calculation of plaque qualities, including induration/infiltration (plaque thickness), erythema, and desquamation (scaling), and the area involved with PsO (48). The investigator or qualified designee will score plaque erythema, scaling and induration (on a scale of 0 to 4) and area of involvement (on a scale of 0 to 6) for 4 body areas: head and neck, upper extremities, trunk, and lower extremities.
Measured: baseline, 3 months, 6 months, 12 months
The number and percentage of patients that initiated brodalumab achieving an Static Physicians Global Assessment (sPGA) score of 0 or 1 at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Static Physicians Global Assessment (sPGA) scale (0 [clear] to 4 [severe]) is designed to evaluate the assessor's global assessment of the patient's psoriasis.
Measured: baseline, 3 months, 6 months, 12 months
The number and percentage of patients that initiated brodalumab achieving a 2 grade or more improvement compared to baseline of the Static Physicians Global Assessment (sPGA) score at 3 months, 6 months, and 12 months post-brodalumab initiation.
The Static Physicians Global Assessment (sPGA) scale (0 [clear] to 4 [severe]) is designed to evaluate the assessor's global assessment of the patient's psoriasis.
Measured: baseline, 3 months, 6 months, 12 months
The percentage change from baseline of the Psoriasis Symptom Inventory (PSI) at 3, 6, and 12 months post-brodalumab initiation.
Psoriasis Symptom Inventory (PSI): The severity of itch, redness, scaling, burning, stinging, cracking, flaking, and pain over the last 24 hours is assessed on a scale of 0 to 4 (0 - not at all, 1- mild, 2 - moderate, 3- severe, 4- very severe) for a total score of 32, with higher scores indicating more severe disease
Measured: baseline, 3 months, 6 months, 12 months
The number and percentage of Adverse Events (AEs) or (Serious Adverse Events) SAEs reported over 12 months post-brodalumab initiation.
Measured: 12 months
Reasons for discontinuation of brodalumab therapy.
Discontinuation reason is captured on the case report form.
