11. No clinically significant abnormalities in 12-lead electrocardiogram (ECG) determined within 28 days before first dose of IMP including a PR interval > 220ms, QRS width > 120ms and QTcF interval > 450 ms.
12. No clinically significant abnormalities in vital signs (e.g., blood pressure (systolic blood pressure > 140 mmHg) / pulse rate, respiration rate, oral temperature) determined within 28 days before first dose of IMP.
13. Participant must be available to complete the study (including all follow-up visits).
14. Participant must satisfy an Investigator about his fitness to participate in the study.
15. Participant must provide written informed consent to participate in the study.

Exclusion Criteria:

1. A clinically significant history of gastrointestinal disorder likely to influence IMP absorption.
2. A clinically significant history of infection in the last 3 months.
3. Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements, any product known to be a substrate mainly metabolised by CYP enzymes within 28 days or 5 half-lives (whichever is longer) prior to the first dose of IMP.
4. Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction.
5. Participants who are unable to demonstrate the ability to swallow multiple "dummy" capsules (i.e., an empty gelatin capsules) of the size proposed for administration in a particular cohort/dose level (up to and including size 00).
6. Participant with a glomerular filtration rate less than 80 mL/min/1.73m2 (calculated by Cockcroft-Gault equation.

9. Participation in a NCE clinical study within the previous 3 months or five half-lives, whichever is longer, or a marketed drug clinical study within the 30 days or five half-lives, whichever is longer, before the first dose of IMP. (Washout period between studies is defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study).
10. Donation of 450 mL or more blood within the 3 months before the first dose of IMP.
11. Vegans, vegetarians or other dietary restrictions (e.g., restrictions for medical, religious or cultural reasons, etc.), which would prevent participants from consuming a high-fat breakfast or standardised meal.
