Abstract

fetched live from OpenAlex

Background: Integrated analyses of Phase III trials are important in characterizing patients (pts) who have the greatest long-term benefits with benralizumab. Aims and Objectives: To examine relationship of exacerbation (EX) frequency during 2 years of benralizumab treatment with baseline (BL) characteristics and efficacy. Methods: We performed post-hoc subgroup integrated analysis of 48-week SIROCCO (Bleecker, Lancet 2016) and 56-week CALIMA (FitzGerald, Lancet 2016) with 56-week BORA extension study (Busse, Lancet Respir Med 2019). Pts receiving benralizumab 30 mg SC every 8 weeks who had BL blood eosinophil counts ≥300 cells/μL were assessed. Pts were evaluated based on EXs experienced during the 2-year analysis period (0, 1, ≥2). Results: BL pre-bronchodilator [BD] FEV1 (%), pre-BD FEV1/FVC, and prior requirement for mechanical ventilation were significantly different for pts with 0–≥2 EXs, with additional significant differences for pts with 0 vs. 2 EXs (table). Greater improvements in ACQ-6 and AQLQ(S)+12 scores were observed for pts with 0 vs. 1/≥2 EXs, while lesser improvement in FEV1 and ACQ-6 and AQLQ(S)+12 scores was observed for the ≥2 EX group vs. the other groups by 16 weeks and was sustained for 2 years. Conclusions: Pts who remained EX-free during 2 years of benralizumab treatment were older at asthma onset, had better lung function, smaller ICU asthma admission rate and BMI, and less gastroesophageal reflux.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
