Lab values

• Any positive result on Screening for serum hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) antibodies.

Other

• Any clinically significant abnormal findings in physical examination, clinical chemistry, hematology, urinalysis results, or vital signs at Screening.
• Any clinically significant abnormalities on 12-lead electrocardiogram (ECG) at Screening.
• Current smokers or those who have smoked or used nicotine products (including e cigarettes).
• Excessive intake of caffeine-containing drinks or food.

• Healthy participants with suitable veins for cannulation or repeated venipuncture.
• All females must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit.

• Have a body mass index (BMI) between 18 and 30 kg/m2 inclusive and weigh at least 50 kg and no more than 120 kg inclusive.
• Participants must have a forced expiratory volume in the first second (FEV1) ≥ 80% of the predicted normal value (based on age, height, ethnicity and gender at birth) and an FEV1/forced vital capacity (FEV1/FVC) \> 70% at the Screening Visit. FEV1/FVC can be reported as ratio ie, 0.7 or a percentage ie, 70%.
