Adalimumab combined with methotrexate versus adalimumab monotherapy in psoriasis: Three‐year follow‐up data of a single‐blind randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: Anti-drug antibodies (ADA) are formed in patients treated with adalimumab (ADL). This might increase clearance of ADL, potentially causing a (secondary) non-response. Combination therapy of ADL and methotrexate (MTX) reduces ADA levels and has a clinical benefit in rheumatologic diseases. In psoriasis however, the long-term effectiveness and safety have not been studied. OBJECTIVES: To investigate the three-year follow-up data of ADL combined with MTX compared to ADL monotherapy in ADL-naive patients with moderate to severe plaque type psoriasis. METHODS: We conducted a multicentre RCT in the Netherlands and Belgium. Randomization was performed by a centralized online randomization service. Patients were seen every 12 weeks until week 145. Outcome assessors were blinded. We collected data on drug survival, effectiveness, safety, pharmacokinetics and immunogenicity of patients that started ADL combined with MTX compared to ADL monotherapy. We present descriptive analysis and patients were analysed according to the group initially randomized to. Patients becoming non-adherent to the biologic were excluded from analyses. RESULTS: Sixty-one patients were included and 37 patients (ADL group n = 17, ADL + MTX group n = 20) continued in the follow-up study after 1 year. After 109 weeks and 145 weeks, there was a trend towards longer drug survival in the ADL + MTX group compared to the ADL group (week 109: 54.8% vs. 41.4%; p = 0.326, week 145: 51.6% vs. 41.4%; p = 0.464). At week 145, 7/13 patients were treated with MTX. In the ADL group, 4/12 patients that completed the study developed ADA, and 3/13 in the ADL + MTX group. CONCLUSIONS: In this small study, there was no significant difference in ADL overall drug survival when it was initially combined with MTX, compared to ADL alone. Discontinuation due to adverse events was common in the combination group. To secure accessible healthcare, combination treatment of ADL and MTX can be considered in individual patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
