RESUMEN

OBJECTIVE: To evaluate the efficacy and safety of three doses of glycopyrrolate metered dose inhaler (GP MDI) in patients with uncontrolled asthma despite treatment with inhaled corticosteroid/long-acting ß2-agonists (ICS/LABA) with or without tiotropium, to characterize the benefit of triple therapy. METHOD: This phase II/III, double-blind study randomized patients to 24 weeks' treatment with twice-daily GP MDI 36 µg, 18 µg, 9 µg, or placebo MDI (all delivered via Aerosphere inhalers), or once-daily open-label tiotropium 2.5 µg. Patients continued their own ICS/LABA regimen throughout the study. The primary endpoint was change from baseline in forced expiratory volume in 1 s (FEV1) area under the curve from 0 - 4 h (AUC0 - 4) at Week 24. Secondary endpoints included patient questionnaires to measure asthma control or symptoms. Safety was also assessed. RESULTS: The primary analysis (modified intent-to-treat) population included 1066 patients. The primary study endpoint was not met (changes from baseline in FEV1 AUC0 - 4 at Week 24 were 294 mL, 284 mL, 308 mL, 240 mL, and 347 mL for GP MDI 36 µg, GP MDI 18 µg, GP MDI 9 µg, placebo, and open-label tiotropium, respectively). There were no significant differences between treatment and placebo in secondary endpoints at Week 24. Post-hoc analyses using post-bronchodilator FEV1 as the baseline measurement, or averaging values across multiple baseline visits, showed a dose-related response to GP MDI. The incidence of adverse events was low and similar across treatments. CONCLUSION: Although this study did not meet its primary endpoint, post hoc analyses identified a dose-related response to GP MDI when alternative definitions of baseline FEV1 were used in the analyses.

RESUMEN

Rationale: In the phase III, 52-week ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial in chronic obstructive pulmonary disease (COPD) (NCT02465567), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) significantly reduced all-cause mortality compared with glycopyrrolate/formoterol fumarate (GFF). However, 384 of 8,509 patients were missing vital status at Week 52 in the original analyses.Objectives: To assess the robustness of the ETHOS mortality findings after additional data retrieval for patients missing Week 52 vital status in the original analyses.Methods: Patients with moderate to very severe COPD and prior history of exacerbation received twice-daily dosing with 320/18/9.6 µg of BGF (BGF 320), 160/18/9.6 µg of BGF (BGF 160), 18/9.6 µg of GFF, or 320/9.6 µg of budesonide/formoterol fumarate (BFF) (all delivered via a single metered-dose Aerosphere inhaler). Time to death (all-cause) was a prespecified secondary endpoint.Measurements and Main Results: In the final retrieved dataset, which included Week 52 vital status for 99.6% of the intent-to-treat population, risk of death with BGF 320 was significantly lower than GFF (hazard ratio, 0.51; 95% confidence interval, 0.33-0.80; unadjusted P = 0.0035). There were no significant differences in mortality when comparing BGF 320 with BFF (hazard ratio, 0.72; 95% confidence interval, 0.44-1.16; P = 0.1721), nor were significant differences observed when comparing BGF 160 against either dual comparator. Results were similar when the first 30, 60, or 90 days of treatment were excluded from the analysis. Deaths from cardiovascular causes occurred in 0.5%, 0.8%, 1.4%, and 0.5% of patients in the BGF 320, BGF 160, GFF, and BFF groups, respectively.Conclusions: Using final retrieved vital status data, triple therapy with BGF 320 reduced the risk of death compared with GFF, but was not shown to significantly reduce the risk of death compared with BFF, in patients with COPD. Triple therapy containing a lower dose of inhaled corticosteroid (BGF 160) was not shown to significantly reduce the risk of death compared with the dual therapy comparators.

RESUMEN

BACKGROUND AND OBJECTIVES: Co-suspension Delivery™ Technology has been developed for the administration of albuterol sulfate pressurised inhalation suspension via metered-dose inhaler (AS MDI, PT007). We assessed the efficacy and safety of AS MDI versus Proventil® in order to determine the optimal dose of AS MDI to take to Phase III clinical trials. METHODS: ASPEN (NCT03371459) and ANTORA (NCT03364608) were Phase II, randomised, crossover, multicentre studies of AS MDI versus Proventil® in patients with persistent asthma. In ASPEN, 46 patients received cumulative-dose treatments (90 µg/inhalation using 1 + 1 + 2 + 4 + 8 inhalations at 30-minute intervals) in 1 of 2 possible sequences: AS MDI/Proventil or Proventil/AS MDI. In ANTORA, 86 patients were randomised to one of 10 treatment sequences of AS MDI (90 µg or 180 µg), placebo MDI, or Proventil (90 µg or 180 µg). The primary endpoints were baseline-adjusted forced expiratory volume in 1 second (FEV1) 30 minutes after each cumulative dose (ASPEN) and change from baseline in FEV1 area under the curve from 0 to 6 h (ANTORA). Safety was assessed in both studies. RESULTS: In ASPEN, AS MDI was equivalent to Proventil (within pre-specified bounds of ± 200 mL) following cumulative doses of albuterol up to 1440 µg for the primary endpoint. In ANTORA, 90 µg and 180 µg doses of AS MDI and Proventil were significantly superior to placebo MDI (p < 0.0001), and AS MDI was non-inferior to Proventil at both doses, based on a margin of 100 mL. No new safety concerns were identified. CONCLUSION: The effects of albuterol delivered via AS MDI and Proventil on bronchodilation were equivalent, supporting the selection of AS MDI 180 µg to be taken into Phase III clinical trials, either alone or in combination with an inhaled corticosteroid. TRIAL REGISTRATION NUMBER: ASPEN (NCT03371459); Date of registration: 29/12/2017. ANTORA (NCT03364608); Date of registration: 15/12/2017.

RESUMEN

Inhaled corticosteroid/long-acting ß2-agonist combination therapy is a recommended treatment option for patients with chronic obstructive pulmonary disease (COPD) and increased exacerbation risk, particularly those with elevated blood eosinophil levels. SOPHOS (NCT02727660) evaluated the efficacy and safety of two doses of budesonide/formoterol fumarate dihydrate metered dose inhaler (BFF MDI) versus formoterol fumarate dihydrate (FF) MDI, each delivered using co-suspension delivery technology, in patients with moderate-to-very severe COPD and a history of exacerbations. In this phase 3, randomised, double-blind, parallel-group, 12-52-week, variable length study, patients received twice-daily BFF MDI 320/10 µg or 160/10 µg, or FF MDI 10 µg. The primary endpoint was change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) at week 12. Secondary and other endpoints included assessments of moderate/severe COPD exacerbations and safety. The primary analysis (modified intent-to-treat) population included 1843 patients (BFF MDI 320/10 µg, n=619; BFF MDI 160/10 µg, n=617; and FF MDI, n=607). BFF MDI 320/10 µg and 160/10 µg improved morning pre-dose trough FEV1 at week 12 versus FF MDI (least squares mean differences 34 mL [p=0.0081] and 32 mL [p=0.0134], respectively), increased time to first exacerbation (hazard ratios 0.827 [p=0.0441] and 0.803 [p=0.0198], respectively) and reduced exacerbation rate (rate ratios 0.67 [p=0.0001] and 0.71 [p=0.0010], respectively). Lung function and exacerbation benefits were driven by patients with blood eosinophil counts ≥150 cells·mm-3. The incidence of adverse events was similar, and pneumonia rates were low (≤2.4%) across treatments. SOPHOS demonstrated the efficacy and tolerability of BFF MDI 320/10 µg and 160/10 µg in patients with moderate-to-very severe COPD at increased risk of exacerbations.
