Efficacy and safety of the long-acting β2-agonist olodaterol over 4 weeks in Japanese patients with chronic obstructive pulmonary disease
Bibliographic record
Abstract
BACKGROUND: Olodaterol is a novel long-acting β2-agonist with proven ≥24-hour duration of action in preclinical and clinical studies. OBJECTIVE: This randomized, double-blind, placebo-controlled, parallel-group study evaluated the dose response of once-daily (QD) olodaterol based on bronchodilator efficacy, safety, and pharmacokinetics over 4 weeks in Japanese patients with chronic obstructive pulmonary disease (COPD). METHODS: All eligible patients were randomized to receive 2 µg, 5 µg, or 10 µg of olodaterol or placebo for 4 weeks via the Respimat Soft Mist inhaler. The primary end point was the change from baseline in trough forced expiratory volume in 1 second (FEV1) after 4 weeks of olodaterol treatment. Secondary end points included trough FEV1 after 1 week and 2 weeks of treatment, FEV1 area under the curve from 0 hour to 3 hours (AUC(0-3)), peak FEV1 from 0 hour to 3 hours (peak FEV1), and corresponding forced vital capacity (FVC) responses. Rescue medication use, COPD symptoms, physician global evaluation, pharmacokinetics, and safety were also assessed. RESULTS: A total of 328 patients with COPD were randomized to receive treatment. All olodaterol doses assessed in the study showed statistically significant increases in trough FEV1 compared to placebo at Day 29 (P<0.0001). Mean increases in peak FEV1 and FEV1 AUC(0-3) compared to placebo were also significant (P<0.0001). A clear dose-response relationship was observed across all treatment groups. FVC responses (trough and FVC AUC(0-3)) supported FEV1 outcomes. All doses of olodaterol were well tolerated, and no safety concerns were identified. CONCLUSION: QD olodaterol demonstrated 24-hour bronchodilator efficacy and was well tolerated in Japanese patients with COPD. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00824382.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
