A Study to Assess the Reaction of Body for Four Different Formulations of AZD9977 (Part A) and Influence of Food and Lower Dose of a Selected Formulation (Part B) in Healthy Male Subjects

Exclusion Criteria

• •1. History of any clinically significant disease or disorder which, in the opinion of the principal investigator (PI), may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.
• •2. History or presence of 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. Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, as judged by the PI, including:
• •4.1. Serum potassium \> 5.0 mmol/L.
• •5. Any clinically significant abnormal findings in vital signs, as judged by the PI, including:
• •5.1. Systolic BP \< 90 mmHg or \> 140 mmHg. 5.2. Diastolic BP \< 50 mmHg or \> 90 mmHg. 5.3. Pulse rate \< 45 or \> 90 beats per minute.
• •6. Any clinically significant abnormalities on 12-lead echocardiogram (ECG), as judged by the PI.
• •7. Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, and human immunodeficiency virus (HIV) antibody.
• •8. Known or suspected history of drug abuse in the 12 months prior to screening, as judged by the PI.
• •9. Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of AZD9977 in this study. The period of exclusion begins 3 months after the final dose or one month after the last visit whichever is the longest. Note: subjects consented and screened, but not randomized in this study or a previous Phase 1 study, are not excluded.
• •10. Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening.
• •11. History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the PI or history of hypersensitivity to drugs with a similar chemical structure or class to AZD9977.
• •12. Current smokers or those who have smoked or used nicotine products (including e cigarettes) within the 3 months prior to screening.
• •13. Positive screen for drugs of abuse, alcohol or cotinine at screening or on admission to the study center.
• •14. Use of drugs with enzyme-inducing properties such as St John's Wort within 3 weeks prior to the first administration of AZD9977.
• •15. 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 first administration of AZD9977 or longer if the medication has a long half life.
• •16. Known or suspected history of alcohol or drug abuse or excessive intake of alcohol in the 12 months prior to screening as judged by the PI.
• •17. Involvement of any AstraZeneca, PAREXEL or study site employee or their close relatives.
• •18. Subjects who have previously received AZD9977.
• •19. Judgment by the PI 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.
• •20. Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
