Description of intervention(s) / exposure
Sixteen healthy adult volunteers will be enrolled in a total of four treatment arms, four participants in each arm. For each participant enrolled in this study, there will be a total of 4 confinement periods. Each confinement period will commence on Day -1, with dosing on Day 1 and discharge on Day 4. Each participant will be assigned to one of 4 treatment arms in a randomised open label manner crossover study design, with the first 8 participants assigned to arms 1 and 2, and the second 8 participants assigned to arms 3 and 4. Each participant will be administered a single dose of each treatment: formulation 1 after a high-fat meal), formulation 1 administered fasted, formulation 2 administered after a high-fat meal and formulation 2 administered fasted. The order of administration will be determined by randomisation. Participants will receive a total of four doses of IMG-7289 (a total of 200 mg) on 4 different days and given during 4 separate treatment periods.
Formulation 1 is the encapsulated IMG-7289 drug substance; it does not contain any excipients whereas Formulation 2 is a formulated capsule containing the IMG-7289 drug substance with the following excipients: fumaric acid, lactose anhydrous, Avicel DG, and magnesium stearate.
For all administrations, a 10-hour overnight fast is required. For the fed administration, a high fat breakfast 30 minutes pre-dose will be required. The participant will be required to stay in the unit for the next three days and three nights following administration to monitor any changes to their health during this time followed by four follow-up visits for each of the study periods.
The study periods will be separated by 14-day wash out intervals. The total maximum study duration for participants in this study is 86 days (approximately 13 weeks, including up to 27 days of screening and 59 days of clinical conduct, inclusive of visit windows).

The clinical facility staff will administer each study treatment; administration will be verified by a second staff member.

Comparator / control treatment
Formulation 2 pharmacokinetics (PK) and safety data will be compared to Formulation 1 PK and safety when given under the same conditions (ie fed or fasted). Additionally, the PK and safety of each formulation will be compared against itself when given under fed and fasted conditions.

9. Female participants must:
a. Be of nonchildbearing potential
b. If of childbearing potential, must have a negative pregnancy test at screening (blood test) and before the first study drug administration (Day -1 urine test).
