Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Participants Achieving Normalized Functioning Health Assessment Questionnaire - Disability Index (HAQ-DI) ≤0.5 at 12 Months of Therapy
Time Frame: 12 Months
|
The HAQ-DI is a patient-reported outcome questionnaire that is used to measure disease associated disability as an assessment of physical function.
It consists of 20 questions referring to 8 domains of functioning.
Participants assess their degree of difficulty when performing the activities over the past week on a 4-item ordinal scale, ranging from 0, "without any difficulty," to 3, "unable to do."
The scores of each of the 8 domains are summed and divided by 8. Higher scores indicate more limitations in physical function.

The PaGADA NRS is an 11-point scale from 0 to 10 that is anchored by 2 verbal descriptors, "very well" and "very poor."
Higher scores represent a higher level of disease activity.
|
Month 6 and Month 12
|
|
Percentage of Participants Achieving Patient Pain Visual Analogue Scale (VAS) ≤15
Time Frame: Month 6 and Month 12
|
The Patient's Assessment of Arthritis Pain is a single-item, patient-reported outcome instrument, used to access the current severity of participants' joint pain in relation to their PsA on a horizontal VAS of 0 to 100 mm.
The Patient's Assessment of Arthritis Pain is anchored by 2 verbal descriptors, "no pain" and "as severe as can imagine."
|
Month 6 and Month 12
|
|
Percentage of Participants Achieving Physician Global Assessment of Disease Activity (PhGADA) NRS ≤2
Time Frame: Month 6 and Month 12

|
Percentage of Participants Achieving HAQ-DI Sore ≤0.5 and at Least a 10% Weight Loss
Time Frame: Month 6 and Month 12
|
The HAQ-DI is a patient-reported outcome questionnaire that is used to measure disease associated disability as an assessment of physical function.
It consists of 20 questions referring to 8 domains of functioning.
Participants assess their degree of difficulty when performing the activities over the past week on a 4-item ordinal scale, ranging from 0, "without any difficulty," to 3, "unable to do."
The scores of each of the 8 domains are summed and divided by 8. Higher scores indicate more limitations in physical function.

|
Percentage of Participants With a Functional Assessment of Chronic Illness Therapy (FACIT) -Fatigue With ≥4-point Increase from Baseline
Time Frame: Month 6 and Month 12
|
FACIT-F is a patient-reported, 13-item questionnaire that specifically assess the self-reported severity of fatigue and its impact upon daily activities and functioning.
The FACIT-F uses 0 ("not at all") to 4 ("very much") Likert scale to assess fatigue and its impact in the past 7 days.
Total score ranges from 0 to 52, based on a rating of 5-point Likert scale.
Scores for negatively worded items are reversed, such that higher scores are better (that is, less fatigue).

Month 6 and Month 12
|
|
Percentage of Participants With a Short-Form 36 (SF36) Physical Component Score (PCS) Minimum Clinically Important Difference (MCID)
Time Frame: Month 6 and Month 12
|
The SF-36v2 acute form is a 36-item, generic, patient-completed measure designed to assess health-related quality of life with 8 health domains.
Items are rated on 3-, 5-, or 6-point Likert scales.
Each domain is individually scored by summing item responses and transforming them to a 0-100 scale.
The eight domains are aggregated into two summary scores: Physical and Mental Component Summaries.
Each summary score is norm based and presented in the form of T-scores, with a mean of 50 and a standard deviation of 10, with higher scores indicating better health status or functioning.
