Abstract
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide; many recent advances have been made in many aspects of the disease. The aim of this article is to illustrate and discuss some of these advances in the management of different types of patients. Large-scale trials have confirmed that long-acting bronchodilator therapy, particularly using the combination of LABA/LAMA, remains the mainstay of COPD treatment, with special attention being paid to careful selection of inhaler devices. The initial choice of pharmacological therapy is based on the GOLD ABCD grouping of patients. It is very important to stress that there is a need to implement a management cycle because COPD is a chronic disease with varying clinical course and a high number of potential comorbidities that may affect morbidity and mortality. Therefore, regular reevaluation of the patient is mandatory. This allows identification of characteristics aimed at maximizing the benefits for a specific patient or a subset of patients. Within this context, the role of the blood eosinophil count as a marker of inhaled corticosteroids response to prevent future exacerbations in patients who, despite appropriate bronchodilator therapy, still suffer from them has been proven to be a useful simple biomarker in medication selection. These advances support the concept of precision medicine, with the goal that patients get the right medicine at the right time for the right reason. Finally, recent studies have shown that early life events may be of critical relevance for the development of COPD. With this as a background, concepts to identify individuals at risk and early identification of cases have become an important objective of current research with the hope of maximizing the effects of therapy and the possibility of impacting disease progression.

Efficacy and safety of glycopyrronium/formoterol delivered via a dry powder inhaler in patients with moderate to severe chronic obstructive pulmonary disease: Results from a multi-centre, open-label, randomised study. Lung India 2022; 39:408-416. [PMID: 36629200 PMCID: PMC9623852 DOI: 10.4103/lungindia.lungindia_92_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 05/05/2022] [Accepted: 05/06/2022] [Indexed: 01/14/2023] Open
Abstract
Background We designed this randomised, open-label, parallel group, multi-centre study to investigate the efficacy and safety of glycopyrronium/formoterol, a long-acting muscarinic antagonist/long-acting β2-agonist fixed dose combination, delivered through a dry powder inhaler (DPI) in patients with chronic obstructive pulmonary disease (COPD). Material and Methods We randomised (1:1) patients with moderate to severe COPD (N = 356) to receive glycopyrronium 25 μg/formoterol 12 μg via DPI twice daily (GF-DPI) or glycopyrronium 50 μg monotherapy via DPI once daily (G-DPI). The primary study endpoint was the mean change from the baseline in pre-dose trough-forced expiratory volume in one second (FEV1) at 12 weeks. Results At week 12, the mean increase from the baseline in pre-dose trough FEV1 was higher in the GF-DPI group (120 ml) than in the G-DPI (60 ml) group. The mean difference (MD) between treatment groups was 0.06 L (95% CI: 0.00-0.12 L, P < 0.0001 for non-inferiority). At week 12, the mean pre-dose forced vital capacity (FVC), 1 hour post-dose FEV1, and post-dose FVC increased significantly from the baseline only in the GF-DPI group (p < 0.0001). The reduction in the COPD assessment test score was greater in the GF-DPI group (p = 0.0379). The average daily number of puffs of rescue medication and the reduction in mean modified Medical Research Council scale, COPD, and Asthma Sleep Impact Scale score at week 12 were similar between groups (p > 0.05). Overall, 35 adverse events and two serious adverse events unrelated to study drugs were reported. Both groups had similar results for overall drug safety. Conclusion The results demonstrate efficacy and safety of GF-DPI in Indian patients with moderate to severe COPD. Treatment with GF-DPI significantly improved the lung function and quality of life and was well tolerated.

Muraki M, Kunita Y, Shirahase K, Yamazaki R, Hanada S, Sawaguchi H, Tohda Y. A randomized controlled trial of long-acting muscarinic antagonist and long-acting β2 agonist fixed-dose combinations in patients with chronic obstructive pulmonary disease. BMC Pulm Med 2021; 21:26. [PMID: 33441146 PMCID: PMC7805049 DOI: 10.1186/s12890-021-01403-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 01/05/2021] [Indexed: 12/18/2022] Open
Abstract
Background In chronic obstructive pulmonary disease (COPD) patients, combination treatment with long-acting muscarinic antagonist (LAMA) and long-acting β2 agonist (LABA) increases forced expiratory volume in one second and reduces symptoms compared to monotherapy. In Japan, three different once-daily fixed-dose combinations (FDCs) have been prescribed since 2015, although a direct comparison of these FDCs has never been performed. The objective of the present study was to compare the effectiveness, preference, and safety of three LAMA/LABA FDCs—glycopyrronium/indacaterol (Gly/Ind), umeclidinium/vilanterol (Ume/Vil), and tiotropium/olodaterol (Tio/Olo)—in patients with COPD. Methods We enrolled 75 COPD outpatients (male:female ratio, 69:6; 77.4 ± 6.9 years). A prospective, randomized, crossover study was conducted on three groups using three FDCs: Gly/Ind; Ume/Vil; and Tio/Olo. Each medication was administered for 4 weeks before crossover (total 12 weeks). After each FDC administration, a respiratory function test and questionnaire survey were conducted. A comparative questionnaire survey of all three LAMA/LABA FDCs was conducted after 12 weeks (following administration of final FDC). Results No significant differences in COPD Assessment Test or modified Medical Research Council dyspnea questionnaire were reported in the surveys completed after each FDC administration; no significant differences in spirometric items were observed. In the final comparative questionnaire survey, patients reported better actual feeling of being able to inhale following Gly/Ind administration compared with Tio/Olo, although no significant differences in adverse events or other evaluations were reported. Conclusions The three LAMA/LABA FDCs administered to COPD patients show similar effects and safety, although some minor individual preference was reported. Trial registration This study retrospectively registered with the University Hospital Medical Information Network Clinical Trials Registry (number UMIN000041342, registered on August 6, 2020).

[PMID: 31284402 PMCID: PMC6680885 DOI: 10.3390/pharmaceutics11070316] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 06/15/2019] [Accepted: 07/02/2019] [Indexed: 12/26/2022] Open
Abstract
Oral inhalation of drugs is the classic therapy of obstructive lung diseases. In contrast to the oral route, the link between in vitro and in vivo findings is less well defined and predictive models and parameters for in vitro-in vivo correlations are missing. Frequently used in vitro models and problems in obtaining in vivo values to establish such models and to identify the action of formulations in vivo are discussed. It may be concluded that major obstacles to link in vitro parameters on in vivo action include lack of treatment adherence and incorrect use of inhalers by patients, variation in inhaler performance, changes by humidity, uncertainties about lung deposition, and difficulties to measure drug levels in epithelial lining fluid and tissue. Physiologically more relevant in vitro models, improvement in inhaler performance, and better techniques for in vivo measurements may help to better understand importance and interactions between individual in vitro parameters in pulmonary delivery.
