Safety, Tolerability and Pharmacokinetics of Multiple Ascending Doses of AZD8871 in Healthy Male Japanese Subjects

Exclusion Criteria

• •1. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site)
• •2. Surgical history clinically relevant for the purpose of the study or any clinically significant illness, medical/surgical procedure or trauma within 4 weeks of Screening.
• •3. History of malignancy of any organ system, treated or untreated within the past 5 years, with the exception of localised basal cell carcinoma of the skin.
• •4. Current smokers, or a smoking history during the last 6 months or total smoking history of more than 10 pack years. Use of electronic cigarettes or other forms of nicotine, current use or use within the last 6 months.
• •Note: Pack years are calculated by dividing the number of cigarettes smoked per day by 20 (the number of cigarettes per pack) and multiplying tis figure by the number of years a person has been smoking. For example, a person who smoked 40 cigarettes a day and has been smoking for 10 years would have a 20 pack-year smoking history (40 cigarettes per day at 20 cigarettes per pack =2; 2 x 10 years of smoking =20 pack-year history).
• •5. Prolonged QTcF corrected using Fredericia's formulae) interval, \> 450 ms at Screening, or family history of long QT syndrome.
• •6. Any clinically significant abnormalities in rhythm, conduction or morphology noted on physical examination, ECG or telemetry recording, prior to randomisation.
• •7. History of excessive use or abuse of alcohol within the past 2 years, defined as: subjects consuming more than 21 (male subjects) units of alcohol a week (1 unit = 1 glass of wine (125 mL) = 1 measure of spirits = half pint of beer).
• •8. History of drug abuse within the past 2 years prior to Screening.
• •9. Donation or loss of \> 400 ml blood and plasma within the previous 3 months prior to Screening.
• •10. History or presence of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity to any drug, as judged by the Investigator or history of hypersensitivity to drugs pharmacologically related to study drug.
• •11. PR (PQ) interval shortening \< 120 ms (PR \> 110 ms but \< 120 ms is acceptable if there is no evidence of ventricular pre-excitation) at Screening.
• •12. PR (PQ) interval prolongation (\> 240 ms), intermittent second (Wenckebach block while asleep is not exclusive), or third degree AV block, or AV dissociation at Screening.
• •13. Persistent or intermittent complete bundle branch block, incomplete bundle branch block.
• •14. Intraventricular conduction delay with QRS (onset of ventricular depolarization) \> 110 ms at Screening.
• •Note: Subjects with QRS \> 110 ms but \< 115 ms are acceptable if there is no evidence of ventricular hypertrophy or pre-excitation.
• •15. Subject who does not agree to follow instructions to avoid partner pregnancy.
• •16. Subject who is not able to adhere to the restrictions on prior and concomitant medications.
• •17. Administered any investigational drug within 3 months prior to first dosing in this study or within the equivalent time of 5 half lives of receiving the last IMP administration, whichever is longer, or on an extended Follow up after receiving an IMP.
• •18. Subjects unable to communicate reliably with the Investigator, even with the help of an interpreter.
• •19. Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
• •20. Subjects who failed any Screening procedures will not be included in the study.
• •21. Subjects with psychiatric disease with limitations to follow instructions in regards of study procedures.
• •22. Subjects with serum potassium values \< 3.5 mmol/L at Screening and on repeat testing.
• •Note: Potassium replacement and repeat testing is allowed if serum potassium concentration was \< 3.5 mmol/L at Screening.
• •23. Any laboratory abnormality or suspicion of any clinically relevant disease or disorder (on history or examination), including uncontrolled diabetes, 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, or any other safety concern in the opinion of the Investigator.
