Change from Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score at Week 24
Query!
Assessment method [1]
0
0
BASDAI is a self-assessment tool that consists of 6 questions relating to 5 major symptoms of ankylosing spondylitis: fatigue, spinal pain, joint pain, enthesitis, qualitative morning stiffness and quantitative morning stiffness. First 5 items were scored on a 10 centimeter (cm) visual analog scale (VAS) ranging from 0 equals to (=) none to 10=very severe. Quantitative morning stiffness was scored on a 10 cm VAS ranging from 0=0 hours to 10=2 or more hours. 2 scores for qualitative and quantitative morning stiffness were averaged, and total BASDAI score was average of the 5 scores of each symptom, ranging from 0 (none) to 10 (very severe). Higher scores indicate greater disease severity.

Change from Baseline in Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (ASDAS-CRP) at Week 24
Query!
Assessment method [1]

0
The ASDAS-CRP is a composite of 5 disease activity variables with only partial overlap. The 4 self-reported items included in this index are back pain (VAS), duration of morning stiffness, peripheral pain/swelling, and participant global assessment of disease activity; these are combined with the C-reactive protein (CRP) value. Selected cut-offs for improvement scores are: a change greater than or equal to (\>=) 1.1 units for "clinically important improvement" and a change \>= 2.0 units for "major improvement.

Change from Baseline in Disease Activity Index for Psoriatic Arthritis (DAPSA) at Week 24
Query!
Assessment method [2]
0
0
DAPSA assessed the joint domain of psoriatic arthritis (PsA) and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), CRP level (milligram/deciliter \[mg/dL\], value less than \[\<\] lower limit of quantification \[LLOQ\] is considered equal to half of the value of LLOQ for numerical calculations), participant assessment of pain (0-10 cm VAS, 0=no pain, 10=worst possible pain), and participant's global assessment of disease activity on arthritis (0 to 10 cm VAS, 0=excellent and 10=poor). A higher score indicates more active disease activity. Negative changes from baseline indicate improvement of PsA disease activity. The assessment does not have a score range with an upper or lower bound.

HAQ-DI score assess functional status of participant. It is 20 question instrument that assess degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area were scored from 0=indicating no difficulty, to 3=indicating inability to perform a task in that area. Total HAQ score is average of the computed categories scores ranging from 0-3 where 0=least difficulty and 3=extreme difficulty. Lower scores are indicative of better functioning. Negative change from baseline indicates improvement of physical function.

0
Percentage of participants with IGA 0/1 response at week 24 among the participants with \>= 3 percent (%) BSA psoriatic involvement and an IGA score of \>= 2 (mild) at baseline will be reported. The IGA documents the investigator's assessment of the participants psoriasis at a given timepoint. Overall lesions are graded for induration, erythema, and scaling using 0 (no evidence), 1 (minimal), 2 (mild), 3 (moderate) and 4 (severe) scale. The IGA score of psoriasis is based upon the average of induration, erythema and scaling scores. The participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).
