Adalimumab for long‐term treatment of psoriatic arthritis: Forty‐eight week data from the adalimumab effectiveness in psoriatic arthritis trial
Bibliographic record
Abstract
OBJECTIVE: To evaluate the efficacy and safety of treatment with adalimumab, a fully human anti-tumor necrosis factor (anti-TNF) monoclonal antibody, over 48 weeks in patients with moderate to severe psoriatic arthritis (PsA). METHODS: Patients who completed the Adalimumab Effectiveness in Psoriatic Arthritis Trial (ADEPT), a 24-week, double-blind study of adalimumab versus placebo in PsA, could elect to receive open-label adalimumab, 40 mg subcutaneously every other week after week 24. Radiographs were obtained at week 48 and were read with radiographs obtained previously. Clinical and radiographic efficacy data were analyzed overall and in patient subsets. Safety data were collected over 48 weeks. RESULTS: At week 48, patients from the adalimumab arm of ADEPT (n = 151) had achieved American College of Rheumatology 20% improvement (ACR20), ACR50, and ACR70 response rates of 56%, 44%, and 30%, respectively. Among those evaluated with the Psoriasis Area and Severity Index (PASI) (n = 69), PASI50, PASI75, PASI90, and PASI100 response rates (> or =50%, > or =75%, > or =90%, and 100% reduction in PASI scores, respectively) were 67%, 58%, 46%, and 33%, respectively (ACR and PASI response rates were analyzed using nonresponder imputation). Improvements in disability, as measured by the Disability Index of the Health Assessment Questionnaire (mean change in score -0.4) were sustained from week 24 to week 48. At week 24 and week 48, the mean changes from baseline in the modified total Sharp score were -0.1 and 0.1, respectively, for patients who received adalimumab for 48 weeks (n = 133), and 0.9 and 1.0, respectively, for patients who received placebo for 24 weeks followed by adalimumab for 24 weeks (n = 141). Adalimumab demonstrated clinical and radiographic efficacy regardless of whether patients were receiving methotrexate (MTX) at baseline. Adalimumab was generally safe and well tolerated through week 48. CONCLUSION: Adalimumab improved joint and skin manifestations, reduced disability, and inhibited radiographic progression over 48 weeks in patients with PsA who were participants in ADEPT. MTX use at baseline was not required for clinical or radiographic efficacy. Adalimumab had a good safety profile through week 48.

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.
