A study to assess the effect of multiple doses of AZD5718 on pharmacokinetics of oral midazolam in healthy subjects

Exclusion Criteria

• • 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 or the volunteer’s ability to participate in the study.
• • History or presence of gastrointestinal, hepatic, or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
• • History or presence of acute pulmonary insufficiency, marked neuromuscular respiratory weakness, obsessional states, phobic states, sleep apnea syndrome, or unstable myasthenia gravis.
• • Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
• • Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, at screening and/or on admission to the Clinical Unit, as judged by the Investigator, including:
• a) Alanine aminotransferase > 1.5 x upper limit of normal (ULN);
• b) Aspartate aminotransferase > 1.5 x ULN;
• c) Bilirubin (total) > 1.5 x ULN; and
• d) Gamma glutamyl transpeptidase > 1.5 x ULN.
• • Any clinically significant abnormal findings in vital signs (blood pressure and pulse; supine) at screening and/or admission to the Clinical Unit, as judged by the Investigator.
• • Any clinically significant abnormalities on 12-lead electrocardiogram at screening, as judged by the Investigator.
• • Any positive result on screening for serum hepatitis B surface antigen, hepatitis C virus antibody, and human immunodeficiency virus antibody.
• • Known or suspected Gilbert syndrome.
• • Known or suspected history of drug abuse in the last 2 years, as judged by the Investigator.
• • Has received another new chemical or biological entity within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or 1 month after the last visit whichever is the longest.
• • Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening.
• • History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the Investigator. History of hypersensitivity to drugs with a similar chemical structure or class to AZD5718 or known hypersensitivity to benzodiazepines or to any formulation excipients.
• • Current smokers or those who have smoked or used nicotine products within the 3 months prior to screening.
• • Positive screen for drugs of abuse or cotinine at screening or on admission to the study unit, or positive screen for alcohol on screening or on admission to the study unit.
• • Use of drugs with enzyme-inducing properties such as St John’s Wort within 3 weeks prior to the first administration of IMP.
• • Use of any prescribed (other than hormone-replacement therapy for females) 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 IMP or longer if the medication has a long half-life.
• • Excessive intake of caffeine-containing drinks or food (e.g., coffee, tea, chocolate) as judged by the Investigator. Excessive intake of caffeine defined as the regular consumption of more than 600 mg of caffeine per day or would likely be unable to refrain from the use of caffeine-containing beverages during confinement at the investigational site.
• • Known or suspected history of alcohol or drug abuse or excessive intake of alcohol as judged by the Investigator. Excessive intake of alcohol defined as the regular consumption of more than 24 g of alcohol per day for men or 12 g of alcohol per day for women.
• • Involvement of any AstraZeneca, Parexel, or study site employee or their close relatives.
• • Subjects who have previously received AZD5718.
• • Subjects with history of lactose intolerance.
• • 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.
• • Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
• • Subjects who cannot communicate reliably with the Investigator.
