Trial Outcomes & Findings for Study To Evaluate The Impact Of Anti-Cyclic Citrullinated Peptide(Anti-CCP) For Management With Enbrel In Patients With Psoriatic Arthritis(PsA) (NCT NCT04428502)

NCT ID: NCT04428502

Last Updated: 2021-09-14

Results Overview

DAPSA assessed the joint domain of PsA and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), C-reactive protein (CRP) level (milligram per deciliter \[mg/dL\]), participant assessment of pain (0 to 10 centimeter \[cm\] visual analog scale (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 DAPSA score indicated more active disease activity. The assessment did not have a score range with an upper or lower bound. The outcome measure compared response between anti-cyclic citrullinated peptide positive and negative participants.

Participant Flow

Data of Iraq's participants, 1) who aged greater than or equal to (\>=) 18 years, 2) who met American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010 criteria for psoriatic arthritis (PsA), and 3) who received etanercept for at least for 1 year from May 2012 until August 2019 in the Baghdad teaching hospital (rheumatology center) were collected. Data collected were assessed in approximately 1.8 months of this retrospective observational study.

PRIMARY outcome

Timeframe: Baseline, Month 1

Population: Data was not evaluated and reported for this outcome measure since CRP variable to calculate DAPSA was not collected from the participants.

DAPSA assessed the joint domain of PsA and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), C-reactive protein (CRP) level (milligram per deciliter \[mg/dL\]), participant assessment of pain (0 to 10 centimeter \[cm\] visual analog scale (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 DAPSA score indicated more active disease activity. The assessment did not have a score range with an upper or lower bound. The outcome measure compared response between anti-cyclic citrullinated peptide positive and negative participants.

OTHER_PRE_SPECIFIED outcome

Timeframe: Month 1, 6 and 12

Population: Analysis was performed on all participants who were included in this study.

DAS28 ESR was calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, ESR (millimeters per hour \[mm/hour\]) and participant's global assessment (PGA) of disease activity (participant rated arthritis activity assessment with transformed scores ranging 0 to 10; higher scores indicated high disease activity). DAS 28 ESR =0.56\*sqrt (PJC28) + 0.28\*sqrt (SJC28) + 0.70\*In (ESR) + 0.014\*PtGA; ln = natural logarithm, sqrt = square root of. DAS28 ESR less than equal to (\<=) 3.2 = low disease activity, DAS28 ESR greater than (\>) 3.2 to 5.1 = moderate to high disease activity. The outcome measure compared response between anti-cyclic citrullinated peptide positive and negative participants.
