Brief summary

The study is an open-label, fixed-sequence, cross-over study conducted at a single Clinical Unit to assess the pharmacokinetics (PK) of midazolam in healthy male and female (non-childbearing potential) subjects when administered alone and in combination with AZD4831 after multiple doses (once daily) of AZD4831 for 10 consecutive days.

Detailed description

The study will consist of 2 treatment periods and will comprise: * A Screening period of maximum 28 days; * Treatment Period 1 and Treatment Period 2: Treatment Period 1: Midazolam only (Day 1). Treatment Period 2: AZD4831 only (Days 2 to 10, once daily dosing) and AZD4831 plus midazolam (Day 11). \- A final Follow-up Visit after the last administration of investigational medicinal product (IMP) (Day 20 \[± 1 day\]). Each subject will be involved in the study for approximately 7 weeks.

Interventions

Subjects will receive oral doses once daily from Days 2-11.

DRUGMidazolam

Subjects will receive oral single doses on Day 1 and Day 11.

Exclusion criteria

* History of any clinically significant disease or disorder. * History or presence of gastrointestinal, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs. * A positive Corona Virus Disease 2019 test at Screening or admission to the Clinical Unit on Day -1. * Any clinically significant abnormalities in clinical chemistry, haematology, or urinalysis results. * Any clinically significant abnormal findings in vital signs. * clinically significant abnormalities on 12-lead electrocardiogram. * Any positive result at the Screening Visit for Hepatitis B surface antigen, hepatitis C virus antibody, and human immunodeficiency virus antibody. * Known or suspected history of drug abuse in the last 2 years. * Current smokers or those who have smoked or used nicotine products within the 3 months prior to the Screening Visit. * Known or suspected history of alcohol or drug abuse. * Use of any prescribed or non-prescribed medication. * Subjects with acute pulmonary insufficiency, marked neuromuscular respiratory weakness, obsessional states, phobic states, sleep apnoea syndrome, or unstable myasthenia gravis. * History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigatoror history of hypersensitivity to drugs with a similar chemical structure or class to AZD4831 or midazolam. * History or ongoing allergy/hypersensitivity to drugs(including but not limited to rash, angioedema, acute urticaria). * Subjects who, in the opinion of the Investigator, have any clinically significant skin condition.
