Reslizumab for Inadequately Controlled Asthma With Elevated Blood Eosinophil Levels
Bibliographic record
Abstract
Background This phase 3 study further characterizes the efficacy and safety of reslizumab (a humanized anti-IL-5 monoclonal antibody) in patients aged 12 to 75 years with asthma inadequately controlled by at least a medium-dose inhaled corticosteroid and with a blood eosinophil count ≥ 400 cells/μL. Methods Patients were randomized to receive reslizumab 0.3 or 3.0 mg/kg or placebo administered once every 4 weeks for 16 weeks (total four doses). The primary end point was change from baseline in pre-bronchodilator FEV 1 over 16 weeks. Secondary end points included FVC, forced expiratory flow at 25% to 75% of FVC (FEF 25%-75% ), patient-reported control of asthma symptoms, short-acting β-agonist (SABA) use, blood eosinophil levels, and safety. Results Reslizumab significantly improved FEV 1 (difference vs placebo [reslizumab 0.3 and 3.0 mg/kg], 115 mL [95% CI, 16-215; P = .0237] and 160 mL [95% CI, 60-259; P = .0018]). Clinically meaningful increases in FVC (130 mL) and FEF 25%-75% (233 mL/s) were observed with reslizumab 3.0 mg/kg. Reslizumab improved scores on the Asthma Control Questionnaire (ACQ) and Asthma Quality of Life Questionnaire (AQLQ) vs placebo (greater effects seen with 3.0 mg/kg; P < .05). The minimally important difference was reached for the AQLQ (reslizumab 3.0 mg/kg) but not on the ACQ. Scores on the Asthma Symptom Utility Index and SABA use were improved with reslizumab. The most common adverse events were worsening of asthma, headache, and nasopharyngitis; most events were mild to moderate in severity. Conclusions Reslizumab improved lung function, asthma control and symptoms, and quality of life. It was well tolerated in patients with inadequately controlled asthma (despite standard therapy) and elevated blood eosinophil levels. Overall, the 3.0-mg/kg dose of reslizumab provided greater improvements in asthma outcomes vs the 0.3-mg/kg dose, with comparable safety.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
