Brief Summary

AZD7594 is in clinical development for the treatment of asthma.

This is a single centre, open-label, single period study in 6 healthy subjects, to determine the mass balance recovery and generate samples to enable metabolite profiling and structural identification of AZD7594.

Each subject will receive a single inhaled 792 µg nominal dose (720 µg delivered dose) of AZD7594 followed by an IV dose of 30 µg [14C]AZD7594 containing not more than (NMT) 6.7 kBq (180 nCi) carbon-14 (14C) as a 1 h infusion. The IV dose will be administered approximately 10 min after the inhaled dose. Subjects will remain resident in the clinical unit up to 168 h post dose (up to Day 8).

Detailed Description

This is a single centre, open-label, single period study in 6 healthy male and non-pregnant, non-lactating female subjects to determine the mass balance recovery after a single intravenous (IV) dose of [14C]AZD7594 and to generate samples to enable metabolite profiling and structural identification of AZD7594 in plasma, urine and faeces. It is planned to enrol 6 subjects to ensure data in at least 4 evaluable subjects. A subject will be considered evaluable if they have provided mass balance and PK samples for up to 48 h after drug administration.

Subjects will be screened for eligibility to participate in the study up to 28 days before dosing. Eligible subjects will be admitted to the clinical unit in the afternoon on the day before dosing (Day 1). Subjects will be dosed on the morning of Day 1 in the fasted state (8 h overnight fast). Before oral inhalation of AZD7594 using the Dry Powder Inhaler (DPI), all subjects must demonstrate their ability to use the DPI as intended. Subjects will receive training with an empty DPI at screening, Day -1 and pre-dose (optional) in accordance with study specific instructions. Each subject will receive a single inhaled 792 µg nominal dose (720 µg delivered dose) of AZD7594 followed by an IV dose of 30 µg [14C]AZD7594 containing 6.7 kBq (180 nCi) carbon-14 (14C) as a 1 h infusion. The infusion of the IV dose will be started approximately 15 min after the inhaled dose. Subjects will remain resident in the clinical unit up to 168 h post dose (up to Day 8).

Whole blood, plasma, urine and faeces will be collected from pre-dose until discharge (168 h post-dose; Day 8). Any accidental sources of elimination (eg emesis) will be collected and sent to the mass balance laboratory for total radioactivity analysis.

Eligibility Criteria

Inclusion Criteria

1. Provision of signed and dated, written informed consent prior to any study specific procedures.

2. Healthy male or non-pregnant, non-lactating female subjects aged 18 to 55 years with suitable veins for cannulation or repeated venepuncture.

3. Have a body mass index of 18.5 to 35.0 kg/m2, and weigh at least 50 kg and no more than 100 kg, as measured at screening.

4. Must have regular bowel movements (ie, average stool production of ≥1 and ≤3 stools per day).

5. Must be willing and able to communicate and participate in the whole study.

6. Must agree to adhere to the contraception requirements defined in Section 9.4 of the protocol.

7. Must demonstrate the ability to use the study inhalation device properly.

Exclusion Criteria

1. History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the volunteer at risk because of participation in the study, or influence the results of the volunteer's ability to participate in the study.

2. History or presence of clinically significant gastrointestinal, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism or excretion of drugs.

3. Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.

4. Subjects with Gilbert's syndrome or subjects with a history of cholecystectomy or gall stones.

5. Subjects with pregnant partners

6. Any confirmed clinically significant abnormalities in clinical chemistry, haematology or urinalysis as judged by the investigator.

7. Any confirmed clinically significant abnormal findings in vital signs or 12-lead ECG as judged by the investigator.

8. Any positive result at screening for serum hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results.

9. Has received any other new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose. Note: subjects consented and screened, but not randomised in this study or a previous Phase I study are not excluded.

10. Plasma donation within 1 month of screening or any blood donation/loss of more than 500 mL of blood during the 3 months prior to screening.

11. History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD7594 or the formulation excipients including lactose. Hay fever is allowed unless it is active.
