Change From Baseline in Disease Activity in Psoriatic Arthritis (DAPSA) at Weeks 2, 4, 8, 12, and 16 Secondary · Baseline, 2, 4, 8, 12, and 16 weeks

DAPSA is calculated by summing the following components: TJC68; SJC66; PGADA \[using VAS on a scale of 0 (very well) to 100 very poor)\]; PGAPI \[using a VAS on a scale of 0 (no pain) to 100 (serious pain)\] and CRP. DAPSA scores 0-4 = remission, 5-14 = low disease activity, 15-28 = moderate disease activity, and \>28 = high disease activity. The DAPSA score has a lower bound of 0 and has no upper bound. A higher DAPSA score indicated more active disease activity. A negative change from baseline indicates improvement.

Change From Baseline in Physician's Global Assessment of Psoriasis (PhGAP) at Weeks 2, 4, 8, 12, and 16 in Participants With Psoriasis Covering ≥ 3% of the Body Surface Area (BSA) at Baseline Secondary · Baseline, 2, 4, 8, 12, and 16 weeks

The PhGAP is used to determine the participant's psoriasis lesions overall at a given time point. The participant's psoriasis disease activity is assessed by a physician according to the grades of induration, erythema, and scaling on a scale of 0 to 5. The sum of the three grades is used to obtain the total average score. PhGAP is based on the total average score on a scale of 0-5 where, 0 = cleared, 1 = minimal, 2 = mild, 3 = moderate, 4 = marked, and 5 = severe. A negative change from baseline indicates improvement.

mNAPSI is used to assess each nail abnormality for each of the participant's nails. Three features or groups of features (pitting, onycholysis together with oil-drop dyschromia, and crumbling) of each fingernail are graded on a scale from 0 (no onycholysis together with oil-drop dyschromia, no pitting, no crumbling) to 3 (\>30 onycholysis together with oil-drop dyschromia, \>50 pitting, \>50% crumbling). Four features (leukonychia, splinter, hemorrhages, hyperkeratosis, and red spots in the lunula) are graded with the score of 1 = present or 0 = absent for each fingernail. Each finger has a sc

Change From Baseline in Leeds Enthesitis Index (LEI) at Weeks 4, 8, 12, and 16 in Participants With Enthesitis at Baseline Secondary · Baseline, 4, 8, 12, and 16 weeks

Enthesitis is assessed using LEI. The enthesitis examination by LEI evaluates the presence or absence of pain by applying local pressure on 6 anatomical sites: medial femoral condyle (left and right), lateral epicondyle (left and right), and the achilles tendon insertion (left and right). Enthesitis at each site is scored as 0 (enthesitis absent) and 1 (enthesitis present). LEI is derived as the sum of the enthesitis score over the 6 sites mentioned above. The total score ranges from 0 to 6, higher scores indicates greater degree of enthesitis. A negative change from baseline indicates improve

Change From Baseline in 12-Item Psoriatic Arthritis Impact of Disease (PsAID-12) Score at Weeks 4 and 16 Secondary · Baseline, 4, and 16 weeks

The PsAID questionnaire assesses the impact of PsA on people's lives. The PsAID is calculated based on 12 numerical rating scales (NRS) questions. Each NRS is assessed as a number between 0 and 10. Total score is calculated as the sum of the individual scores, (some of which were multiplied by a weighting factor) divided by 20 for a total possible score of 0 to 10, where higher score indicates worse impact of disease. A negative change from baseline indicates improvement.

Sponsor's own description

The primary objective of this study is to evaluate the effect of filgotinib compared to placebo as assessed by the American College of Rheumatology 20% improvement (ACR20) response in participants with active psoriatic arthritis who are naive to biologic disease-modifying anti-rheumatic drug (DMARD) therapy. The study consists of two parts, the Main Study and the Long Term Extension (LTE).
