2. Participants who are overtly healthy, in the opinion of the Investigator, as
determined by medical evaluation including medical history, physical examination,
vital signs, ECGs and laboratory tests. Participants who do not qualify based on a
reversible condition or mild intercurrent illness may be re-screened after the
underlying condition is resolved.

kg, inclusive, if female. Body Mass Index within the range =19 and =30 kg/m2
(inclusive), at screening.
4. Female participants who engage in heterosexual intercourse must be of non-childbearing
potential, defined as either surgically sterile (ie, hysterectomy, bilateral
salpingectomy, or bilateral oophorectomy), OR be postmenopausal with at least 1 year
of amenorrhea, OR must be using an established form of highly effective method of
contraception from the time of screening until at least 90 days after the last dose of
study intervention. Female participants must not be lactating and must agree to have
no egg donation plan during the study and for 90 days after the last dose of study
intervention.
5. Male participants must agree to use a condom when sexually active with a female
partner of childbearing potential from screening until at least 90 days after the last
dose of study intervention (or be surgically sterile [ie, vasectomy with
documentation]; or remain abstinent, when this is in line with the preferred and usual
lifestyle). Male participants should also agree not to donate sperm for the duration
of the study and until at least 90 days after the last dose of study intervention.
6. Must be 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.
Exclusion Criteria:
1. Known hypersensitivity, allergy, intolerance, or idiosyncratic reaction to the study
intervention, or any of the excipients contained in the intervention formulation. If
any history of anaphylaxis or reaction to other agents, discussion with (and approval
by) the Investigator and Sponsor is required.
2. Any concomitant disease, condition, or treatment that could interfere with the conduct
of the study or that would, in the opinion of the Investigator or Sponsor, pose an
unacceptable risk to the participant in the study or interfere with the interpretation
of study data.
3. History of dysphagia or any gastrointestinal disease (including Gilbert's syndrome)
that affects the participants ability to swallow and/or affects drug absorption.
4. Positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test at any time
prior to administration of the study intervention if SARS-CoV-2 test is performed.
5. Any clinically significant (at the discretion of the Investigator) abnormalities in
laboratory test results. Total bilirubin value up to 1.5 times the upper normal limit
of normal can be acceptable if associated with normal conjugated bilirubin value
(unless the participant has documented Gilbert's Syndrome).
6. History of immunological disorders, auto-immune disorders, acquired or congenital
immune deficiency, including autoimmune rheumatic disease.
Note: participants with mild asthma controlled with occasional rescue inhaler only (no
chronic therapy; no inhaled corticosteroids), and mild atopic dermatitis controlled

on serological tests for hepatitis B surface antigen (HbsAg).
9. Positive serological tests for human immunodeficiency virus (HIV) antibody and/or
hepatitis C virus (HCV) antibody at the initial screening visit.
10. Blood donation of >400 mL within 3 months before screening or >200 mL within 4 weeks
before screening or plan to donate blood during study period.
11. Acute or febrile illness within 7 days prior to the first dose of study intervention
or participants with evidence of active infection.
12. Evidence of an active or suspected cancer or a history of malignancy within the
previous 3 years, except for the following, which did not require systemic therapy and
are considered cured: nonmelanoma skin cancer, curatively treated localized prostate
cancer, or other in situ cancer.
13. History of drug abuse or a positive drug abuse test result at screening or D-1.
14. History of alcohol abuse or a positive alcohol test result at screening or D-1.
15. Use of prescription medications or herbal remedies within 14 days or 5 elimination
half-lives (whichever is longer) of study intervention administration or use of over
the counter (OTC) drugs within 7 days of study intervention administration (apart from
recommended doses of vitamin/mineral supplements, OTC analgesics, or other agents that
have been discussed with and approved by the Investigator and Sponsor). Participants
who used recommended doses of paracetamol/ibuprofen for acute conditions (e.g.,
headache) will not be excluded. Participants who have been on hormone replacement
therapy (HRT) or oral contraception for a period of at least 2 months prior to the
start of screening will not be excluded from the study, provided the contraceptive or
HRT regimen will remain unchanged during the conduct of the study.
16. Use of any known liver enzyme inducer or liver enzyme inhibiting food or beverage

test results or their own safety.

(whichever is longer) prior to administration of the study intervention.
20. Abnormal cardiac conditions and ECG:
i. The Fridericia algorithm corrected QT interval (QTcF) of ECG during screening
period is >450 ms for males and >470 ms for females or is considered abnormal with
clinical significance as determined by the Investigator.
ii. Sustained (ie, 3 independent measurements within 30 minutes) HR (pulse) >100 or
