Abstract

fetched live from OpenAlex

<h3>Introduction</h3> Upadacitinib (UPA) has been shown to induce and maintain clinical response and remission in ulcerative colitis (UC) patients (Pts). The benefits of high (30 mg) versus low (15 mg) dose UPA as maintenance treatment in UC remains to be established. <h3>Methods</h3> Pts with a clinical response after 8 weeks of UPA 45 mg once daily (OD) induction (16-week induction responders excluded from analysis) were re-randomised into maintenance 1:1:1 to UPA 15 mg OD, UPA 30 mg OD, or placebo (PBO) OD. The percentage of Pts in each group with mild, moderate and severe (Adapted Mayoscore &lt;5, 5 to ≤7 and &gt;7 respectively) UC was assessed at weeks 0 and 52 of maintenance. For each UPA dose, area under the curve (AUC) analysis of Pts in clinical remission per Partial Adapted Mayo score (score ≤2 with no subscore &gt;1) at Weeks 0, 4, 8, 12, 20, 28, 36, 44 and 52 of maintenance was used to calculate the number of weeks patients were in clinical remission. <h3>Results</h3> At Week 0 of maintenance, at least 91% of Pts had mild disease and no Pts had severe disease across treatment groups (see table 1). At week 52of maintenance, 19.7% more Pts in the UPA 30 mg group were in a lesser disease severity state (10.5% and 9.2% more Pts with mild and moderate disease, respectively) compared with the UPA 15 mg group. Based on AUC analysis, Pts in the PBO, UPA 15 mg and UPA 30 mg groups were in clinical remission for 15.8 (95% CI: 12.2, 19.5), 30.5 (95% CI: 26.4, 34.6), and 34.4 (95% CI: 30.5, 38.3) weeks, respectively. Pts in the UPA 30 mg group were in clinical remission for an additional 3.8 weeks over a year of maintenance versus UPA 15 mg group. <h3>Conclusions</h3> After 52-weeks of maintenance treatment with UPA 30 mg OD, Pts had less severe disease and were in clinical remission for approximately 1 additional month/year vs patients treated with UPA 15 mg OD indicating a clinical benefit of 30mg UPA as maintenance treatment in UC.

Teacher imitation

Not 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.
