Eligibility Criteria

Inclusion Criteria

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

2. Healthy male and/or female subjects aged 18 - 50 years with suitable veins for cannulation or repeated venipuncture.

3. Females must have a negative pregnancy test at screening and on admission to the unit, must not be lactating and must be of non-childbearing potential, confirmed at screening by fulfilling 1 of the following criteria:

• Post-menopausal defined as amenorrhea for at least 12 months or more following cessation of all exogenous hormonal treatments and follicle-stimulating hormone (FSH) levels in the post-menopausal range.
• Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy, but not tubal ligation.

4. Have a body mass index (BMI) between 18 and 30 kg/m2, inclusive, and weigh at least 50 kg and no more than 100 kg, inclusive.

5. Have a FEV1 (Forced expiratory volume in 1 second in liters) ≥ 80% of the predicted value at screening.

6. Provision of signed, written and dated informed consent for optional genetic/biomarker research.

Exclusion Criteria

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

2. History or presence of gastrointestinal (GI), 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 administration of investigational medicinal product (IMP).

4. Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, as judged by the investigator.

5. Any positive result on screening for serum hepatitis B surface antigen (HBsAg), hepatitis C antibody and human immunodeficiency virus (HIV).

• Diastolic blood pressure (DBP) < 50mmHg or ≥ 90 mmHg
• Heart Rate < 45 or > 85 beats per minute (bpm)

7. Any clinically significant abnormalities in rhythm, conduction or morphology of the resting electrocardiogram (ECG) and any clinically significant abnormalities in the 12-lead ECG, as considered by the investigator that may interfere with the interpretation of QTc (QT [ECG interval measured from the onset of the QRS complex to the end of the T wave] interval corrected for heart rate) interval changes, including abnormal ST-T-wave morphology, particularly in the protocol defined primary lead or left ventricular hypertrophy, at screening.

8. PR (PQ [ECG interval measured from the onset of the P wave to the onset of the QRS complex]) interval prolongation (> 240 ms) intermittent second (Wenckebach block while asleep is not exclusive) or third degree atrioventricular (AV) block, or AV dissociation, at screening.

Subjects with QRS (ECG interval measured from the onset of the QRS complex to the J point) > 110 ms but < 115 ms are acceptable if there is no evidence of, for example, ventricular hypertrophy or pre-excitation, at screening.

10. Serum/plasma potassium levels are outside the normal range and lower than 3.5 to 5.1 mEq/L (milliequivalents per liter) at screening and prior to dosing.

17. Excessive intake of caffeine containing drinks or food (e.g., coffee, tea, chocolate), as judged by the investigator.

18. Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks prior to the administration of IMP.

19. Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to the administration of IMP or longer if the medication has a long half-life.

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

21. Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the administration of IMP in this study. The period of exclusion is 3 months after the final dose from a previous study.

Note: Subjects consented and screened, but not randomized in this study or a previous phase I study, are not excluded.

22. Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.

23. Involvement of any Astra Zeneca, PAREXEL or study site employee or their close relatives.

24. Judgment by the investigator that the subject should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions and requirements.

25. Subjects who are vegans or have medical dietary restrictions.

26. Subjects who cannot communicate reliably with the investigator.

In addition, any of the following is regarded as a criterion for exclusion from the genetic research:
