An Evaluation of the Pharmacokinetics, Safety, and Tolerability of Aclidinium/Formoterol Fixed-Dose Combination Administered in Chinese Patients with Moderate-to-Severe Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Background and objectives

The aim of this study was to evaluate the pharmacokinetics, safety, and tolerability of aclidinium bromide/formoterol fumarate in patients from China with moderate-to-severe chronic obstructive pulmonary disease (COPD).

Methods

In this open-label, repeat-dose, 5-day pharmacokinetic study (NCT03276078) of inhaled aclidinium bromide/formoterol fumarate 400/12 µg twice daily, plasma concentrations of aclidinium, formoterol, and two aclidinium metabolites (LAS34823, LAS34850) were assessed (days 1 and 5). Adverse event (AE) data were collected.

Results

Twenty patients (15 [75%] males) with a mean age of 59.2 years were included. Median (range) time to maximum concentration on days 1 and 5 was 0.08 (0.08-0.50) and 0.08 (0.08-0.50) h, respectively, for aclidinium; and 1.00 (0.08-3.00) and 0.08 (0.08-1.50) h, respectively, for formoterol. Mean elimination half-life and accumulation ratio for area under the concentration-time curve during a dosage interval (AUC_τ) was 19.42 h and 2.0, respectively, for aclidinium; and 14.06 h and 1.4, respectively, for formoterol. Steady-state maximum concentration (C_max,ss) and AUC_τ on day 5 were 60.86 pg/mL and 168.80 h·pg/mL, respectively, for aclidinium; and 6.47 pg/mL and 31.98 h·pg/mL, respectively, for formoterol. Aclidinium produced high coefficients of variation (day 1: AUC_τ 79.0%, C_max 84.5%; day 5: AUC_τ 82.2%, C_max 150.0%). Few AEs were reported, typically one per patient. One patient discontinued due to a serious AE (considered possibly unrelated to treatment).

Conclusions

Aclidinium/formoterol 400/12 µg twice daily was well-tolerated in patients from China with moderate-to-severe COPD. Safety findings were consistent with the known safety profile.

Project description:BackgroundThe combination of aclidinium bromide, a long-acting anticholinergic, and formoterol fumarate, a long-acting beta2-agonist (400/12 μg twice daily) achieves improvements in lung function greater than either monotherapy in patients with chronic obstructive pulmonary disease (COPD), and is approved in the European Union as a maintenance treatment. The effect of this combination on symptoms of COPD and exacerbations is less well established. We examined these outcomes in a pre-specified analysis of pooled data from two 24-week, double-blind, parallel-group, active- and placebo-controlled, multicentre, randomised Phase III studies (ACLIFORM and AUGMENT).MethodsPatients ≥40 years with moderate to severe COPD (post-bronchodilator forced expiratory volume in 1 s [FEV1]/forced vital capacity <70 % and FEV1 ≥30 % but <80 % predicted normal) were randomised (ACLIFORM: 2:2:2:2:1; AUGMENT: 1:1:1:1:1) to twice-daily aclidinium/formoterol 400/12 μg or 400/6 μg, aclidinium 400 μg, formoterol 12 μg or placebo via Genuair™/Pressair®. Dyspnoea (Transition Dyspnoea Index; TDI), daily symptoms (EXAcerbations of Chronic pulmonary disease Tool [EXACT]-Respiratory Symptoms [E-RS] questionnaire), night-time and early-morning symptoms, exacerbations (Healthcare Resource Utilisation [HCRU] and EXACT definitions) and relief-medication use were assessed.ResultsThe pooled intent-to-treat population included 3394 patients. Aclidinium/formoterol 400/12 μg significantly improved TDI focal score versus placebo and both monotherapies at Week 24 (all p < 0.05). Over 24 weeks, significant improvements in E-RS total score, overall night-time and early-morning symptom severity and limitation of early-morning activities were observed with aclidinium/formoterol 400/12 μg versus placebo and both monotherapies (all p < 0.05). The rate of moderate or severe HCRU exacerbations was significantly reduced with aclidinium/formoterol 400/12 μg compared with placebo (p < 0.05) but not monotherapies; the rate of EXACT-defined exacerbations was significantly reduced with aclidinium/formoterol 400/12 μg versus placebo (p < 0.01) and aclidinium (p < 0.05). Time to first HCRU or EXACT exacerbation was longer with aclidinium/formoterol 400/12 μg compared with placebo (all p < 0.05) but not the monotherapies. Relief-medication use was reduced with aclidinium/formoterol 400/12 μg versus placebo and aclidinium (p < 0.01).ConclusionsAclidinium/formoterol 400/12 μg significantly improves 24-hour symptom control compared with placebo, aclidinium and formoterol in patients with moderate to severe COPD. Furthermore, aclidinium/formoterol 400/12 μg reduces the frequency of exacerbations compared with placebo.Trial registrationNCT01462942 and NCT01437397 (ClinicalTrials.gov).

Project description:BackgroundCombining two long-acting bronchodilators with complementary mechanisms of action may provide treatment benefits to patients with chronic obstructive pulmonary disease (COPD) that are greater than those derived from either treatment alone. The efficacy and safety of a fixed-dose combination (FDC) of aclidinium bromide, a long-acting muscarinic antagonist, and formoterol fumarate, a long-acting β2-agonist, in patients with moderate to severe COPD are presented.MethodsIn this 24-week double-blind study, 1692 patients with stable COPD were equally randomized to twice-daily treatment with FDC aclidinium 400 μg/formoterol 12 μg (ACL400/FOR12 FDC), FDC aclidinium 400 μg/formoterol 6 μg (ACL400/FOR6 FDC), aclidinium 400 μg, formoterol 12 μg, or placebo administered by a multidose dry powder inhaler (Genuair®/Pressair®)*. Coprimary endpoints were change from baseline to week 24 in 1-hour morning postdose FEV1 (FDCs versus aclidinium) and change from baseline to week 24 in morning predose (trough) FEV1 (FDCs versus formoterol). Secondary endpoints were change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score and improvement in Transition Dyspnea Index (TDI) focal score at week 24. Safety and tolerability were also assessed.ResultsAt study end, improvements from baseline in 1-hour postdose FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC or ACL400/FOR6 FDC compared with aclidinium (108 mL and 87 mL, respectively; p < 0.0001). Improvements in trough FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC versus formoterol (45 mL; p = 0.0102), a numerical improvement of 26 mL in trough FEV1 over formoterol was observed with ACL400/FOR6 FDC. Significant improvements in both SGRQ total and TDI focal scores were observed in the ACL400/FOR12 FDC group at study end (p < 0.0001), with differences over placebo exceeding the minimal clinically important difference of ≥4 points and ≥1 unit, respectively. All treatments were well tolerated, with safety profiles of the FDCs similar to those of the monotherapies.ConclusionsTreatment with twice-daily aclidinium 400 μg/formoterol 12 μg FDC provided rapid and sustained bronchodilation that was greater than either monotherapy; clinically significant improvements in dyspnea and health status were evident compared with placebo. Aclidinium/formoterol FDC may be an effective and well tolerated new treatment option for patients with COPD.Trial registrationClinicaltrials.gov NCT01437397.

Project description:BackgroundLABA (long-acting β2-agonists) and/or LAMA (long-acting muscarinic antagonists) represent the first treatment options for patients with symptomatic COPD. Although both display different mechanisms of activity, in combination they have a stronger broncho-dilating effect than monotherapy; hence, a combination of both LABA and LAMA is particularly recommended for patients whose symptoms cannot be sufficiently improved by a single active ingredient. To date, only few data have been collected regarding the therapeutic outcomes of approved LABA/LAMA fixed-dose combinations (FDCs) under everyday (real-life) conditions in non-clinical trial settings.Objective and methodsThe main objective of the DETECT study was to investigate the impact of aclidinium/formoterol (AB/FF, b.i.d.), glycopyrronium/indacaterol (GLY/IND, q.d.) and umeclidinium/vilanterol (UME/VL, q.d.) in patients with COPD in daily clinical practice. Therefore, a prospective, non-randomized, 12-month, observational study was implemented to assess the effectiveness of these treatments in patients who had been switched to FDC within the last 3 months or for whom such a changeover was intended. Changes in lung function were analyzed by the forced expiratory volume (FEV1) and forced vital capacity (FVC) measures. Quality of life and well-being were evaluated by the COPD Assessment Test (CAT™). Furthermore, a number of exacerbations and early morning COPD symptoms were documented.ResultsIn total, 3653 patients were enrolled. FEV1 and FVC values significantly improved during the study with AB/FF (increase by 0.09 ± 0.40 L and 0.10 ± 0.57 L, respectively; p<0.0001), GLY/IND (0.06±0.38/0.05±0.51 L; p<0.0001 and p=0.0025) and UME/VL (0.12±0.39/0.10±0.52 L; p<0.0001). CAT scores decreased indicating improved COPD (AB/FF, 4.17±8.30; GLY/IND, 3.66±7.88; UME/VL, 4.06±7.96; p<0.0001). Moreover, the number of exacerbations as well as early morning COPD symptoms similarly diminished in all treatment groups. A comparable proportion of patients with adverse drug reactions was recorded: AB/FF, 4.07% of patients; GLY/IND, 3.52%; UME/VL, 3.64%.ConclusionIn summary, AB/FF, GLY/IND and UME/VL provided clinical benefits in lung function, quality of life and early morning COPD symptoms in a broad cohort of COPD patients under routine medical practice conditions. All three treatments were well tolerated.

Project description:Background'Clinically important deterioration' (CID) is a composite endpoint measuring worsening of the key clinical features of chronic obstructive pulmonary disease (COPD), namely lung function, patient-reported outcomes, and exacerbations. ACLIFORM and AUGMENT were two 24-week, randomized, double-blind, phase III studies assessing twice-daily (BID) aclidinium bromide (AB) 400 μg/formoterol fumarate (FF) 12 μg. This pooled post-hoc analysis assessed the effects of AB/FF 400/12 μg on both first and sustained CID events versus placebo and monotherapies in patients with moderate to severe COPD.MethodsA first CID event was defined as the occurrence of a moderate/severe exacerbation or the worsening from baseline in ≥1 of the following: trough forced expiratory volume in 1 second (FEV1; ≥100 mL), Transition Dyspnea Index (TDI) focal score (≥1 unit), or St George's Respiratory Questionnaire (SGRQ) total score (≥4 units). A 'sustained' CID was defined as a worsening maintained at all subsequent visits from appearance to week 24 or a moderate/severe exacerbation at any time. CID events were assessed at three visits (weeks 4, 12, and 24); trough FEV1 was also measured at weeks 1 and 18.ResultsAB/FF 400/12 μg reduced the risk of a first CID event by 45% versus placebo (hazard ratio [HR] 0.55, p < 0.001), 18% versus FF 12 μg (HR 0.82, p < 0.01), and 15% versus AB 400 μg (HR 0.85, p < 0.05). Similarly, AB/FF 400/12 μg reduced the risk of a sustained CID event by 48% versus placebo (HR 0.52, p < 0.001) and 22% versus FF 12 μg (HR 0.78, p < 0.01). AB/FF 400/12 μg reduced the risk of a first or sustained CID event for all four components versus placebo (trough FEV1 and TDI, first and sustained CID, all p < 0.001; SGRQ first CID p < 0.001; SGRQ sustained CID, p < 0.01; exacerbations first and sustained CID, both p < 0.05) and TDI and SGRQ versus FF 12 μg (TDI, first and sustained CID both p < 0.05; SGRQ first CID p < 0.01), and SGRQ versus AB 400 μg (first CID, p < 0.05).ConclusionsAB/FF 400/12 μg BID may provide greater airway stability and fewer exacerbations or deteriorations in lung function, health status, or dyspnea compared with placebo or monotherapies.Trial registrationClinicaltrials.gov NCT01462942 (ACLIFORM); registered 26 October 2011.

Project description:BackgroundHCP1004 is a newly developed fixed-dose combination of naproxen (500 mg) and esomeprazole strontium (20 mg) that is used in the treatment of rheumatic diseases and can reduce the risk of nonsteroidal anti-inflammatory drug-associated ulcers. The aim of this study was to evaluate the pharmacokinetics (PK) and safety of HCP1004 compared to VIMOVO(®) (a marketed fixed-dose combination of naproxen and esomeprazole magnesium).Subjects and methodsAn open-label, randomized, two-treatment, two-sequence crossover, single-dose clinical study was conducted in 70 healthy volunteers. In each period, a reference (VIMOVO(®)) or test (HCP1004) drug was administered orally, and serial blood samples for PK analysis were collected up to 72 hours after dosing. To evaluate the PK profiles, the maximum plasma concentration (Cmax) and the area under the concentration-time curve from 0 to the last measurable time (AUC0-t) were estimated using a noncompartmental method. Safety profiles were evaluated throughout the study.ResultsSixty-six of the 70 subjects completed the study. The Cmax (mean ± standard deviation) and AUC0-t (mean ± standard deviation) for naproxen in HCP1004 were 61.67 ± 15.16 µg/mL and 1,206.52 ± 166.46 h · µg/mL, respectively; in VIMOVO(®); these values were 61.85 ± 14.54 µg/mL and 1,211.44 ± 170.01 h · µg/mL, respectively. The Cmax and AUC0-t for esomeprazole in HCP1004 were 658.21 ± 510.91 ng/mL and 1,109.11 ± 1,111.59 h · ng/mL, respectively; for VIMOVO(®), these values were 595.09 ± 364.23 ng/mL and 1,015.12 ± 952.98 h · ng/mL, respectively. The geometric mean ratios and 90% confidence intervals (CIs) (HCP1004 to VIMOVO(®)) of the Cmax and AUC0-t of naproxen were 0.99 (0.94-1.06) and 1.00 (0.98-1.01), respectively. For esomeprazole, the geometric mean ratios (90% CI) for the Cmax and AUC0-t were 0.99 (0.82-1.18) and 1.04 (0.91-1.18), respectively. The overall results of the safety assessment showed no clinically significant issues for either treatment.ConclusionThe PK of HCP1004 500/20 mg was comparable to that of VIMOVO(®) 500/20 mg for both naproxen and esomeprazole after a single oral dose. Both drugs were well-tolerated without any safety issues.

Project description:RationaleThe purpose of this study was to investigate the clinical efficacy and safety of a fixed-dose combination of mometasone furoate/formoterol fumarate (MF/F) administered via a metered-dose inhaler in subjects with moderate-to-very severe chronic obstructive pulmonary disease (COPD).MethodsThis multicenter, double-blind, placebo-controlled trial had a 26-week treatment period and a 26-week safety extension. Subjects (n = 1196), at least 40 years old, were current or ex-smokers randomized to twice-daily inhaled MF/F 400/10 μg, MF/F 200/10 μg, MF 400 μg, F 10 μg, or placebo. The trial's co-primary endpoints were mean changes from baseline, as area under the curve (AUC), in forced expiratory volume (FEV(1)) over 0-12 hours (AUC(0-12 h) FEV(1)) with MF/F versus MF, and in morning (AM) pre-dose (trough) FEV(1) with MF/F versus F after 13 weeks of treatment. Key secondary endpoints were the effects of MF/F on respiratory health status using the Saint George's Respiratory Questionnaire (SGRQ), symptom-free nights, partly stable COPD at 26 weeks, and time to first COPD exacerbation.ResultsThe largest improvements in AUC(0-12 h) FEV(1) were observed with MF/F 400/10 μg and MF/F 200/10 μg. Serial spirometry results demonstrated that bronchodilator effects with MF/F occurred rapidly (within 5 minutes), persisted for 12 hours after dosing, and were sustained over the 26-week treatment period. Similar findings were observed for AM pre-dose FEV(1), for which effects were further investigated, excluding subjects whose AM FEV(1) data were incorrectly collected after 2 days from the last dose of study treatment. Improvements in SGRQ scores surpassed the minimum clinically important difference of more than four units with both MF/F treatments. At 26 weeks, no notable between-treatment differences in the occurrence and nature of adverse events (AEs) were reported. No unexpected AEs were observed. Overall, 90 subjects reported AEs considered to be treatment-related, the most common of which were lenticular opacities, dysphonia, and oral candidiasis.DiscussionIn conclusion, MF/F treatments improved lung function and respiratory health status, reduced exacerbations, and were well tolerated in subjects with moderate-to-very severe COPD.
