Abstract

fetched live from OpenAlex

Background The long-term safety and efficacy of a novel Co-Suspension™ Delivery Technology glycopyrrolate (GP)/formoterol fumarate (FF) 18/9.6 μg fixed-dose combination metered dose inhaler (GFF MDI) were investigated in a 28-week safety extension study (PINNACLE-3, NCT01970878) of two randomized controlled Phase III trials (PINNACLE-1 and -2; NCT01854645 and NCT01854658) in subjects with moderate-to-very severe chronic obstructive pulmonary disease (COPD). Methods Subjects completing 24 weeks' treatment with GFF MDI, GP MDI, FF MDI (all twice-daily) or open-label tiotropium 18 μg (once-daily) in PINNACLE-1 or -2 were randomly selected to continue treatment for 28 weeks. The target enrollment for PINNACLE-3 was 850 subjects. Safety and efficacy were evaluated over 52 weeks. Results Of 3274 subjects randomized to active treatment in PINNACLE-1 or -2, 892 entered PINNACLE-3. Incidences of adverse events, serious adverse events and major adverse cardiovascular events were similar across treatment groups with no unexpected safety findings. For change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV 1 ), treatment differences for GFF MDI versus GP MDI, FF MDI and open-label tiotropium over 52 weeks were 57, 65 and 25 mL, respectively (p ≤ 0.0117). Average daily rescue medication use was significantly reduced for GFF MDI versus GP MDI and open-label tiotropium (p ≤ 0.0002). Statistically significant improvements were observed with GFF MDI versus monocomponents in Self-Administered Computerized Transition Dyspnea Index focal score, and in St George's Respiratory Questionnaire total score versus GP MDI. Conclusions Results confirmed the long-term safety and tolerability of GFF MDI 18/9.6 μg twice-daily in subjects with moderate-to-very severe COPD. Improvements in efficacy endpoints were also sustained over 52 weeks.

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.
