AZD8871

To evaluate the efficacy of inhaled AZD8871 600 μg in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

To evaluate the efficacy of inhaled AZD8871 600 μg in patients with moderate to severe COPD. At each visit, patients are asked to evaluate the impact of COPD on their wellbeing and daily life on a 6-point Likert scale ranging from 0 to 5, with higher scores indicating a higher impact of COPD. The CAT is expressed as a total score, which is a sum of the 8 questions, ranging from 0 to 40.

Recording adverse events. An AE is the development of an undesirable medical condition or the deterioration of a preexisting 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). In clinical studies, an AE can include an undesirable medical condition occurring at any time, including run-in or washout periods, even if no study treatment has been administered.

Recording concomitant medications. Any concomitant medication or therapy given to the subject during the study conduct will be recorded.

A full physical examination will include the examination of the following: general appearance, eyes, ears, nose, throat, chest/respiratory, heart/cardiovascular, gastrointestinal/liver, musculoskeletal/extremities, dermatological/skin, thyroid/neck, lymph nodes, neurological/psychiatric. A brief physical examination will include assessment of the following: skin, lungs, cardiovascular system and abdomen (liver and spleen). A complete physical examination will be performed at the Screening and Follow-up visit. Only relevant findings detected will be recorded in the physical examination findings.

Recording vital signs. Systolic and diastolic blood pressure (in mmHg) will be measured after at least 10 minutes (can be reduced to 5 minutes at collection time points within the 1st hour after dosing) resting, and also, before taking any blood sample and conducting any spirometry. Measurements will be carried out with subject in the supine position and preferably always on the same arm. Subject's oral body temperature will be measured at each vital signs collection.

Haematocrit, hemoglobin, erythrocytes (red blood cells), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), leucocytes (white blood cells), differential blood count (neutrophils, lymphocytes, monocytes, eosinophils and basophils) and thrombocytes (platelets)

Electrolytes: sodium, potassium, calcium, chloride and inorganic phosphorus. Enzymes: AST, ALT, ALP, GGT, LDH, creatine kinase. Substrates: glucose (fasting), total cholesterol, triglycerides, creatinine, TBL, total protein, albumin, uric acid, urea and BUN. Endocrinology: T4, TSH. Viral serology: HIV I and II antibodies, hepatitis C antibodies, HBsAg, HBc. Coagulation: INR, PT, aPTT.

A 12-lead ECG will be obtained after the subject rested in the supine position for at least 10 minutes (can be reduced to 5 minutes at collection time points within the first hour after dosing; using the sites own ECG machines when not performing dECGs and using the same machine as the dECGs when time points coincide).

Recording telemetry findings. A 2-lead real-time telemetry ECG will be performed for at least 4 hours on Day 1 and then on Days 1, 10 and 16 from 30 minutes predose until 24 hours postdose.

pH, blood, leucocytes, protein, glucose, bilirubin, urine bilirubin, ketones and nitrites. If clinically relevant abnormalities are detected (positive result in dipstick), microscopy (RBC, WBC and cast \[hyaline, granular and cellular\]).

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).

A full physical examination included the examination of the following: general appearance, eyes, ears, nose, throat, chest/respiratory, heart/cardiovascular, gastrointestinal/liver, musculoskeletal/extremities, dermatological/skin, thyroid/neck, lymph nodes, neurological/psychiatric. A brief physical examination included assessment of the following: skin, lungs, cardiovascular system and abdomen (liver and spleen). A complete physical examination was performed at the Screening Visit. Any abnormal finding assessed as the investigator as clinically relevant was reported as an adverse event.

Systolic and diastolic BP (SBP/DBP) (in mmHg) measured after at least 10 minutes (could be reduced to 5 minutes at collection time points within the 1st hour after dosing) resting, and also before taking any blood sample and conducting any spirometry. Measurements were carried out with subject in the supine position and preferably always on the same arm. Subject's oral body temperature was measured at each vital signs collection.

Haematocrit, haemoglobin, erythrocytes (red blood cells), mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, leucocytes (white blood cells), differential blood count (neutrophils, lymphocytes, monocytes, eosinophils and basophils), and thrombocytes (platelets).

A 12-lead ECG was obtained after the subject rested in the supine position for at least 10 minutes (could be reduced to 5 minutes at collection time points within the first hour after dosing) (using the sites own ECG machines when not performing dECGs and using the same machine as the dECGs when time points coincided).

Recording of telemetry findings. A 2-lead real-time telemetry ECG was performed for at least 4 hours on Day -1 and then on Days 1, 10 and 16 from 30 minutes pre-dose until 24 hours post-dose. The telemetry monitoring system was reviewed by the Investigator or research nurse and paper printouts of any clinically important events were stored as source data.

Electrolytes: Sodium, potassium, calcium, chloride and inorganic phosphorus Enzymes: AST, ALT, ALP, GGT, LDH, creatine-kinase Substrates: Glucose (fasting), total cholesterol, triglycerides, creatinine, TBL, total protein, albumin, uric acid, urea and BUN Endocrinology: T4, TSH Viral Serology: HIV I and II antibodies, Hepatitis C antibodies, Hepatitis B surface antigen, Hepatitis B core (HBc) immunoglobulin antibodies Coagulation parameters: INR, PT, aPTT

Dipstick analysis was performed at the centre and included: pH, blood, leucocytes, protein, glucose, bilirubin, urobilinogen, ketones and nitrites. If clinically relevant abnormalities were detected (positive result in dipstick), microscopy (RBC, WBC and casts \[Hyaline, Granular and Cellular\]) were performed.

The AZ ECG Centre performed the digital ECG (dECG) analysis in this study, using the EClysis© system, version 3.3, or higher. At protocol-indicated time points, 12-lead continuous dECG was recorded over at least 5 minutes with the Schiller Cardiovit CS-200 recorder (Schiller AG, Baar, Switzerland) and transmitted to the AZ central dECG repository, according to AZ ECG Centre´s standard procedures for settings, recording and transmission of dECGs
