study specific procedures, sampling, and analyses.
3. Subjects must be =18 and less than or equal to 65 years of age at the time of signing
the Informed Consent Form.

history, physical examination, laboratory tests, and cardiac monitoring.
5. Individuals who weigh =50 kg and who have a body mass index (BMI) between 18.0 and
30.0 kg/m2, inclusive.
6. Either male or female.
7. Female subjects must have a negative pregnancy test result at screening and check-in

8. Female subjects must be of non-childbearing potential, as confirmed at screening by
fulfilling one of the following criteria:
1. Post-menopausal women must have had =12 months of spontaneous amenorrhea with a
follicle stimulating hormone (FSH) concentration consistently =40 mIU/mL and must
have a negative pregnancy test result at screening and check-in.
2. Surgically sterile women, defined as those who have had a hysterectomy, bilateral
ovariectomy (oophorectomy), bilateral salpingectomy, or bilateral tubal ligation.
Women who are surgically sterile must provide documentation of the procedure by
an operative report or relevant medical records, or by ultrasound, and must have
a negative pregnancy test result at screening and check-in.
9. Male subjects must be vasectomized.
Exclusion criteria
1. History of any clinically important disease or disorder 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.
2. History of any significant psychiatric disorder according to the criteria of the
Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (American
Psychiatric Association 2013) which, in the opinion of the Investigator, could be
detrimental to subject safety or could compromise study data interpretation.
3. Male subjects with a history of oligospermia or azoospermia or any other disorder of
the reproductive system.
4. Subjects who are undergoing treatment or evaluation for infertility.
5. History or presence of gastrointestinal, hepatic or renal disease or any other
condition known to interfere with absorption, distribution, metabolism or excretion of
drugs.
6. Any clinically important illness, medical/surgical procedure or trauma within 4 weeks
of administration of Investigational Product.
7. Any clinically important abnormalities noted at the screening assessments in clinical
chemistry, hematology, or urinalysis results as judged by the Investigator.
8. Any positive result on screening for serum hepatitis B surface antigen, hepatitis C
antibody and human immunodeficiency virus antibodies.
9. Abnormal vital signs, after 10 minutes supine rest, defined as any of the following:
1. Systolic BP <90 mmHg or =140 mmHg.
2. Diastolic BP <50 mmHg or =90 mmHg.
3. HR <45 or >85 beats per minute.
10. 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
the Investigator's opinion, may interfere with the interpretation of QTc interval
changes, including abnormal ST-T-wave morphology.
11. ECG interval measured from the onset of the QRS complex to the end of the T wave (QT)
interval corrected for HR using Fridericia's formula (QTcF) >450 ms or family history
of long QT syndrome.
12. ECG interval measured from the onset of the P wave to the onset of the QRS complex
(PR[PQ]) interval shortening <120 ms (PR >110 ms but <120 ms is acceptable if there is
no evidence of ventricular pre-excitation).
13. PR(PQ) interval prolongation (>240 ms), persistent or intermittent second (Wenckebach
block while asleep is not exclusive) or third degree atrioventricular (AV) block, or
AV dissociation.
14. Persistent or intermittent complete bundle branch block (BBB), incomplete bundle
branch block (IBBB), or intraventricular conduction delay (IVCD) with ECG interval
measured from the onset of the QRS complex to the J point (QRS) >110 ms. Subjects with
QRS >110 ms but <115 ms are acceptable if there is no evidence of, eg, ventricular
hypertrophy or pre-excitation.
15. Known or suspected history of drug abuse as judged by the Investigator.
16. Current smokers or those who have smoked or used nicotine products within the previous
3 months.
17. History of alcohol abuse or excessive intake of alcohol defined as an average weekly
intake of >21 units or an average daily intake of >3 units for men or an average
weekly intake of >14 units or an average daily intake of >2 units for women. One unit
is equivalent to a half pint (250 mL) of beer, 1 measure (25 mL) of spirits, or 1
glass (125 mL) of wine. If a subject is currently diagnosed with abuse of or
dependence on alcohol, the subject will not be allowed to enroll in the study, unless
the alcohol abuse/dependence is in full (complete, not partial), sustained (>1 year)
remission.
18. Positive screen for drugs of abuse at screening or admission to the unit or positive
screen for alcohol at screening to the unit prior to administration of IP.
19. History of severe allergy/hypersensitivity or ongoing clinically important
allergy/hypersensitivity, as judged by the Investigator, or history of
hypersensitivity to drugs with a similar chemical structure or class to AZD4041.
20. Plasma donation within 1 month of screening or any blood donation/blood loss >500 mL
during the 3 months prior to screening.
21. Excessive intake of caffeine-containing drinks or food (eg, coffee, tea, chocolate) as
judged by the Investigator.
22. Use of drugs with enzyme inducing properties, such as St John's wort, within 3 weeks
prior to administration of IP.
23. Use of any prescribed or nonprescribed 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
administration of IP or longer if the medication has a long half life.
24. Use of any prescribed or nonprescribed oral and topical inhibitors/inducers of CYP3A4
(including shampoo).
25. Use of hormone replacement therapy.
26. Subjects who have previously received AZD4041.
27. Has received another new chemical entity (defined as a compound that has not been
approved for marketing) within 3 months of administration of IP 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. Note: subjects consented and screened, but not
randomized in this study or a previous Phase I study, are not excluded.
28. Involvement of any AstraZeneca or study site employee or their close relatives.
29. Judgement by the Investigator that the subject should not participate in the study if
they have any ongoing or recent (ie, 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.
30. Subjects who are vegans or have medical dietary restrictions.
31. Subjects who cannot communicate reliably with the Investigator.
