Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
---|---|---|
Proportion of Patients Achieving DAS28-CRP<=3.2
Periodo de tiempo: 24 weeks
|
DAS28-CRP: Disease Activity Score based on a count of swollen and tender joints (out of 28 joints), blood test measures of inflammation (CRP) and the patient's own assessment.
Scores can take any positive value with a lower value indicating a better clinical condition.
DAS28-CRP score of <=3.2 indicates low disease activity.
<2.6 means disease remission
|
24 weeks
|
Proportion of Patients Achieving DAS28-ESR<=3.2
Periodo de tiempo: 24 weeks
|
DAS28-ESR: Disease Activity Score based on a count of swollen and tender joints (out of 28 joints), blood test measures of inflammation (ESR) and the patient's own assessment.
Scores can take any positive value with a lower value indicating a better clinical condition.
DAS28-ESR score of <=3.2 indicates low disease activity.
<2.6 means disease remission

Change in HAQ-DI Score From Baseline
Periodo de tiempo: 24 weeks
|
The HAQ-DI is a standardized measure of physical function in arthritis.
The HAQ-DI questionnaire contains 20 items divided into 8 domains that measure: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities.
Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3).
Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 very severe, high-dependency disability.

ACR20
Periodo de tiempo: 12 weeks
|
The ACR is a standard criteria originally developed to measure the effectiveness of various arthritis medications or treatments in clinical trials for RA, but is also widely used in PsA.
The ACR measures improvement in tender joint count (TJC) or swollen joint count (SJC), and improvement in at least 3 of the following 5 parameters: Patient Global Assessment (PtGA), Physician's Global Assessment of Disease Activity (PhGA), physical function (using HAQ-DI) and acute phase reactant (using CRP).
ACR 20 response is achieved if ≥ 20% improvement in tender joint count (TJC) or swollen joint count (SJC) as well as a ≥ 20%/≥ 50%/≥ 70% improvement in ≥ 3 of the other 5 parameters.

Change in Disease Activity in Psoriatic Arthritis Score (DAPSA) Score From Baseline
Periodo de tiempo: 24 weeks
|
Disease Activity in Psoriatic Arthritis Score (DAPSA) score is a the sum of swollen joint count (66 joints), tender joint count (68 joints), CRP (mg/dL), Patient's Assessment of Pain (on a 10-unit VAS;0=no pain, 10=worst possible pain), and Patient's Global Assessment of Disease Activity (arthritis, on a 10-unit VAS; 0 to 100 centimeter [cm] VAS, 0=excellent and 10=poor).
Change from baseline in DAPSA measures the change in disease activity, where a negative change indicates an improvement and a positive change indicates worsening of disease activity.

Percentage of Participants in MDA
Periodo de tiempo: 24 weeks
|
MDA for PsA was defined as fulfilling at least 5 of the following 7 criteria: TJC ≤ 1 (out of TJC68 assessed in this study), SJC ≤ 1 (out of SJC66 assessed in this study), PASI ≤ 1 or BSA ≤ 3; Patient's assessment of pain VAS ≤ 15, PtGA VAS ≤ 20, HAQ-DI score ≤ 0.5, and tender entheseal points ≤ 1
|
24 weeks
|
Change in Tender Joint Count (TJC) 68 from baseline
Periodo de tiempo: 12 weeks and 24 weeks
|
TJC is determined by physical examination of 68 joint counts that are assessed for tenderness.
|
12 weeks and 24 weeks
|
Change in Swollen Joint Count (SJC) 66 from baseline
Periodo de tiempo: 12 weeks and 24 weeks
|
SJC is determined by physical examination of 66 joint counts that are classified as either swollen or not swollen.
