Long-term safety and efficacy of glycopyrrolate/formoterol metered dose inhaler using novel Co-Suspension™ Delivery Technology in patients with chronic obstructive pulmonary disease
Bibliographic record
Abstract
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.

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.
