Efficacy and safety of tofacitinib in an open-label, long-term extension study in patients with psoriatic arthritis who received adalimumab or tofacitinib in a Phase 3 randomized controlled study: a post hoc analysis
Bibliographic record
Abstract
BACKGROUND: Data on treatment switching directly from tumor necrosis factor inhibitors to tofacitinib in psoriatic arthritis (PsA) are limited. This post hoc analysis assessed efficacy and safety outcomes in patients with PsA who directly switched to tofacitinib in a long-term extension (LTE) study after receiving adalimumab (ADA) in a Phase 3 study, compared with those who continued to receive tofacitinib. METHODS: Patients with active PsA received tofacitinib 5 mg twice daily (BID) or ADA 40 mg once every 2 weeks in a 12-month, randomized, double-blind study (OPAL Broaden) and then continued or switched to tofacitinib 5 mg BID and maintained this dose in an open-label LTE study (OPAL Balance). Efficacy was assessed 3 months before the last visit and at the last visit in the Phase 3 study, and at month 3 (or month 6 for select outcomes) in the LTE study and included rates of ≥ 20/50/70% improvement in American College of Rheumatology response criteria, Psoriasis Area and Severity Index ≥ 75% improvement, Health Assessment Questionnaire-Disability Index (HAQ-DI) response (decrease from baseline ≥ 0.35 for patients with baseline HAQ-DI ≥ 0.35), Psoriatic Arthritis Disease Activity Score ≤ 3.2, and minimal disease activity; and change from baseline in Functional Assessment of Chronic Illness Therapy-Fatigue score. Safety was assessed at months 3 and 12 in both studies via incidence rates (patients with first events/100 patient-years). RESULTS: Overall, 180 patients were included (ADA→tofacitinib 5 mg BID: n = 91; continuing tofacitinib 5 mg BID: n = 89). At Phase 3 baseline, patients in the ADA→tofacitinib 5 mg BID group tended to be younger and have less active disease compared with those continuing tofacitinib. Efficacy was similar between groups in the Phase 3 study, and was maintained to month 3 or 6 in the LTE study. Treatment-emergent adverse events (AEs), serious AEs, and serious infections were generally similar in the Phase 3 and LTE studies, and between groups within each study. CONCLUSION: Tofacitinib efficacy and safety were similar in patients with PsA who directly switched from ADA to tofacitinib and those who continued tofacitinib, suggesting that patients can be directly switched from ADA to tofacitinib without any washout period. TRIAL REGISTRATION: NCT01877668; NCT01976364.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
