Females who are pregnant or lactating (all female participants must have a negative highly sensitive serum pregnancy test at screening and a negative urine pregnancy test at admission) Prior Study Participation 15. Participants who have received any IMP in a clinical research study within the 90 days prior to Day 1, or less than 5 elimination half-lives prior to Day 1, whichever is longer 16. Participants who have previously been administered IMP in this study. Participants who have taken part in Part 1 are not permitted to take part in Parts 2 and 3 and participants who have taken part in Part 2 are not permitted to take part in Part 3 17. Donation of blood or plasma within the previous 3 months or loss of greater than 400 mL of blood Prior and Concomitant Medication 18. Participants who are taking, or have taken, any prescribed or over-the-counter drug or herbal remedies (other than up to 4 g of paracetamol per day, hormonal contraception or HRT) in the 14 days before first IMP administration (see Section 11.4) 19. Participants who have received a COVID-19 vaccine within 7 days before first IMP administration Lifestyle Characteristics 20. History of any drug or alcohol abuse in the past 2 years 21. Regular alcohol consumption in males \>21 units per week and females \>14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type) 22. A confirmed positive alcohol breath test at screening or admission 23. Current smokers and those who have smoked within the last 12 months. A confirmed breath carbon monoxide reading of greater than 10 ppm at screening or admission 24. Current users of e-cigarettes and nicotine replacement products and those who have used these products within the last 12 months 25. Confirmed positive drugs of abuse test result (drugs of abuse tests are listed in Appendix 1) 26. Participant with a vegan or vegetarian diet (Part 2 only) Other 27.

A score of 20 or more on the Beck Depression Inventory (BDI-II), and/or a response of 1, 2 or 3 for item 9 of this inventory (related to suicidal ideation) \[7\]. Note, individuals with a BDI-II score of 17-19 may be enrolled, at the discretion of the investigator, if they do not have a medical history of psychiatric conditions and their mental state is not considered to pose additional risk to the health of the individual or to the execution of the trial and interpretation of the data 29. Participants who are, or are immediate family members of, a study site or sponsor employee 30. Failure to satisfy the investigator of fitness to participate for any other reason
