AZD8871 is a new chemical entity possessing long-acting effect in a single molecule which presents a novel treatment approach to chronic obstructive pulmonary disease [COPD] and potentially also asthma (in combination with an inhaled corticosteroid [ICS]). The therapeutic goal for AZD8871 is a treatment with greater efficacy than single mechanism bronchodilators, with an equivalent or superior safety and tolerability profile. The primary purpose of this study is to check the safety and tolerability of AZD8871 at steady state. A multiple ascending dose (MAD) design has been selected for this study following the first time in man (FTIM), single ascending dose (SAD) study. Three dose levels will be tested in an ascending manner. The first dose to be administered will be 300 μg and the 2 subsequent doses will be decided based on safety, tolerability and pharmacokinetic (PK) data generated in the previous dose. The aim of this study is to also enable further investigations in healthy subjects to evaluate and develop AZD8871 as a dual action bronchodilator with an acceptable side-effect profile compared to other inhaled bronchodilators on the market as a treatment for COPD and asthma.

Primary | Number of Participants With =1 Treatment Emergent Adverse Event in Any Category. | Recording treatment emergent adverse events (TEAE). A TEAE was defined as an AE with onset (start date/time) after the first dose of investigational medicinal product. An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal results of an investigation (e.g., laboratory findings, ECG). |
