Abstract
BACKGROUND: Chronic spontaneous urticaria is an idiopathic syndrome defined by recurring itch, hives, or angioedema (or a combination of these symptoms) for more than 6 weeks. Remibrutinib, an oral, highly selective Bruton's tyrosine kinase inhibitor, showed efficacy and favorable safety in phase 2b trials. Data from phase 3 trials are needed. METHODS: -antihistamines. Patients were randomly assigned in a 2:1 ratio to receive oral remibrutinib at a dose of 25 mg twice daily or placebo. The primary end point was the change from baseline to week 12 in the urticaria activity score during a 7-day period (UAS7), which comprises severity scores for itch and hives during 1 week (scores range from 0 to 42, with higher scores indicating greater severity). Key secondary end points included adverse events and a UAS7 of 6 or lower at weeks 2 and 12 and a UAS7 of 0 at week 12. RESULTS: A total of 470 patients in REMIX-1 and 455 in REMIX-2 were randomly assigned to receive either remibrutinib (313 and 300 patients, respectively) or placebo (157 and 155 patients, respectively). The remibrutinib group had a significantly greater decrease in the UAS7 at week 12 than the placebo group (least-squares mean [±SE] change, -20.0±0.7 vs. -13.8±1.0 [P<0.001] in REMIX-1 and -19.4±0.7 vs. -11.7±0.9 [P<0.001] in REMIX-2), which appeared to be sustained through week 24. At week 12, significantly more patients in the remibrutinib group than in the placebo group had a UAS7 of 6 or lower (REMIX-1, 49.8% vs. 24.8% [P<0.001]; REMIX-2, 46.8% vs. 19.6% [P<0.001]) and a UAS7 of 0 (REMIX-1, 31.1% vs. 10.5% [P<0.001]; REMIX-2, 27.9% vs. 6.5% [P<0.001]). The percentages of patients with any adverse event and with serious adverse events were similar in the remibrutinib group and the placebo group, although a higher percentage of patients in the remibrutinib group than in the placebo group had petechiae (3.8% vs. 0.3% in the combined groups). CONCLUSIONS: Treatment with oral remibrutinib resulted in a significant improvement in a composite measure of itching and hives at week 12.

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 it
