Eligibility Criteria

Inclusion Criteria

• Participants between 20 and 65 years of age inclusive, at the time of signing the informed consent.
• Volunteers who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring.
• Participant capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
• Participants who have evidence of completed vaccination for Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with an approved vaccine.
• Body weight within the range 45 - 100 killogram (kg) and body mass index (BMI) within the range 18-29.9 kg per meter square (/m2) (inclusive).
• Japanese participants are eligible based on meeting all of the following:
• Participants born in Japan
• Descendants of four ethnic Japanese grandparents and two ethnic Japanese parents.
• Have lived outside Japan for less than (<) 10 years at the time of screening
• Chinese participants are eligible based on meeting all of the following
• Participants born in mainland China, Hong Kong or Taiwan
• Descendants of four Chinese grandparents and two Chinese parents

• Declaration of familial Caucasian/European ancestry (having 2 parents of Caucasian/European ancestry and 4 grandparents of Caucasian/European ancestry)
• Male or female participant
• Male participants are eligible to participate if they agree to the following for at least 28 weeks after the dose of study intervention: Refrain from donating sperm plus either be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR must agree to use contraception/barrier as detailed below: agree to use a male condom and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak when having sexual intercourse with a woman of childbearing potential who is not currently pregnant.
• A female participant is eligible to participate if she is of non-reproductive potential.
• Capable of giving signed informed consent.

Exclusion Criteria

• History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, haematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data.
• Personal or family history of cardiomyopathy.
• Abnormal blood pressure at screening as determined by the investigator.
• History of symptomatic herpes zoster.
• Evidence of active or latent tuberculosis (TB) as documented by medical history, examination, and TB testing with a positive (not indeterminate) QuantiFERON test.

• Previous or current history of bleeding diathesis, excessive bleeding or coagulation disorders.
• History of significant medical illness in the opinion of the investigator would interfere with the study procedures and / or assessments.

• Positive Hepatitis C Ribonucleic acid (RNA) test result at screening or within 3 months prior to first dose of study intervention.
• Abnormal clinically significant echocardiogram at screening, as assessed by the investigator.
• Cardiac troponin or N-terminal pro B-type natriuretic peptide (NT-proBNP) levels out of normal range at screening.
• Positive pre-study drug/alcohol screen.
• Positive human immunodeficiency virus (HIV) antibody test.
• Positive coronavirus disease 2019 (COVID-19): SARS-CoV2 polymerase chain reaction (PCR) or lateral flow test of a combined throat and nasopharyngeal swab or nasal swab only.
• Regular alcohol consumption within 6 months prior to the study defined as: an average weekly intake of >14 units for males and >14 units for females. One unit is equivalent to 8 grams of alcohol: a half-pint (approximately 240 mL) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
