History of significant allergy/ hypersensitivity to AZD4041 or products related to AZD4041 as well as severe allergy/hypersensitivity reactions (like angioedema) to any drugs Presence or history of significant gastrointestinal, liver or kidney disease, or any other condition that is known to interfere with drug absorption, distribution, metabolism, or excretion, or known to potentiate or predispose to undesired effects History of any significant disease, including [but not necessarily limited to] significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic, or dermatologic disease Maintenance therapy with any drug or significant history of drug dependency or alcohol abuse (> 21 units/week or > 3 units/day for men; > 14 units/week or > 2 units/day for women; intake of excessive alcohol, acute or chronic) History of any significant psychiatric disorder according to the criteria of the Diagnostic and Statistical manual of Mental Disorders, 5th Edition (DSM-5, American Psychiatric Association 2013) which, in the opinion of the Investigator, could be detrimental to subject safety or could compromise study data interpretation. History of substance use disorder, other than nicotine or caffeine (as per DSM-5 criteria) Use of any prescription drugs, including hormone replacement therapy in the 28 days prior to the first study drug administration, that in the opinion of an Investigator would put into question the status of the participant as healthy Use of St. John's wort in the 28 days prior to the first study drug administration Positive test result for alcohol and/or drugs of abuse at Screening or prior to the first study drug administration Any clinically significant illness, medical/surgical procedure or trauma within the 28 days prior to the first study drug administration Any abnormal or clinically significant findings in laboratory test results at Screening that would, in the opinion of an Investigator, increase the subject's risk of participation, jeopardize complete participation in the study, or compromise interpretation of study data Positive screening results to HIV Ag/Ab combo, hepatitis B surface antigen, or hepatitis C virus tests Showing suicidal tendency as per the C SSRS questionnaire administered at Screening  Any abnormal vital signs, after 10 minutes supine rest, as defined in the list below, at the Screening Visit/or Day -2 Out of range tests may be repeated once for each visit at the discretion of an Investigator.  Systolic BP < 90 mmHg or >140 mmHg Diastolic BP < 50 mmHg or > 90 mmHg Heart Rate <45 or >85 beats per minute (bpm) Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG and any clinically important abnormalities in the 12-lead ECG which, in an Investigator's opinion, may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology, particularly in the protocol-defined primary lead or left ventricular hypertrophy at Screening or prior to the first study drug administration Prolonged QT interval corrected for HR using Fridericia's formula (QTcF) > 440 ms at Screening or prior to the first study drug administration Shortened QTcF < 340 ms at Screening or prior to first study drug administration Known family history of long QT syndrome ECG interval measured from the onset of the P wave to the onset of the complex between Q and S waves (QRS complex) (PR [PQ]) interval shortening < 120 ms (PR > 110 ms but < 120 ms is acceptable if there is no evidence of ventricular preexcitation) at Screening or prior to the first study drug administration PR (PQ) interval prolongation (> 220 ms), persistent or intermittent second (Wenckebach block while asleep is not exclusive), or third degree atrioventricular (AV) block, or AV dissociation at Screening or prior to the first study drug administration Persistent or intermittent complete bundle branch block, incomplete bundle branch block, or intraventricular conduction delay (IVCD) with ECG interval measured from the onset of the QRS complex to the J point (QRS) > 110 ms.
