Abstract
BackgroundChronic rhinosinusitis with nasal polyps (CRSwNP) frequently remains uncontrolled despite maximal medical therapy and sinonasal surgery, presenting several unmet needs and challenges. Omalizumab previously demonstrated efficacy in CRSwNP in duplicate phase 3, randomized, placebo-controlled trials (POLYP 1, POLYP 2).ObjectiveThis open-label extension evaluated the continued efficacy, safety, and durability of response of omalizumab in adults with CRSwNP who completed POLYP 1 or 2.MethodsAfter 24 weeks of omalizumab or placebo in POLYP 1 and 2, patients (n = 249) received open-label omalizumab plus background nasal mometasone therapy for 28 weeks and were subsequently followed for 24 weeks after omalizumab discontinuation. Efficacy end points assessed change from baseline for the coprimary end points, Nasal Polyp Score and Nasal Congestion Score, and the secondary end points of Sino-Nasal Outcome Test 22, Total Nasal Symptom Score and its components, and University of Pennsylvania Smell Identification Test scores. Safety objectives included incidence of adverse events and adverse events leading to omalizumab discontinuation.ResultsPatients who continued omalizumab experienced further improvements across coprimary end points and secondary end points through 52 weeks. Patients who switched from placebo to omalizumab experienced favorable responses across end points through week 52 that were similar to POLYP 1 and 2 at week 24. After omalizumab discontinuation, scores gradually worsened over the 24-week follow-up, but remained improved from pretreatment levels for both groups. The safety profile was similar to previous reports.ConclusionsThe efficacy and safety profile from this study supports extended omalizumab treatment up to 1 year for CRSwNP with inadequate response to nasal corticosteroids.

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
