Abstract

fetched live from OpenAlex

OBJECTIVE: Although treatment with corticosteroids induces remission in Crohn's disease, prolonged exposure to corticosteroids is undesirable. This randomised clinical trial evaluated the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor (sargramostim), an activator of innate immunity, in corticosteroid-dependent patients with Crohn's disease. DESIGN: Patients were randomised in a 2:1 ratio, to sargramostim 6 microg/kg subcutaneously once daily or placebo for up to 22 weeks. The study consisted of (1) an adjunctive phase (weeks 1-4) in which patients received study drug plus corticosteroid therapy; (2) a forced corticosteroid tapering phase (weeks 4-14); and (3) an observation phase (4 weeks) in which patients received study drug plus prednisone < or =7.5 mg. The primary endpoint was corticosteroid-free remission (Crohn's Disease Activity Index (CDAI) < or =150) 4 weeks after corticosteroid elimination. Secondary endpoints were corticosteroid-free response (CDAI decreased by > or =100) and induction of remission in patients who reduced the dose of corticosteroid to 2.5-7.5 mg. RESULTS: Eighty-seven patients were randomised to sargramostim and 42 to placebo. Significantly more sargramostim-treated patients than placebo patients achieved corticosteroid-free remission (18.6% vs 4.9%; p = 0.03). Similar differences were seen for corticosteroid-free response and in patients who tapered corticosteroids to 2.5-7.5 mg/day. Sargramostim treatment was also associated with significant improvements in health-related quality of life. Patients who received sargramostim were more likely to experience musculoskeletal pain, injection site reactions and dyspnoea. CONCLUSIONS: Sargramostim was more effective than placebo for inducing corticosteroid-free remission in patients with Crohn's disease with corticosteroid dependence. Sargramostim may provide significant benefit in this population if these findings are confirmed.

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.
