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.

Summary
Brief summary
This is a study of safety and tolerability of a drug called IMG-7289; also known as bomedemstat. The study will compare the amount of IMG-7289 that is in the blood after taking a single dose of 2 different formulations of IMG-7289, both with food and without food. IMG-7289 is being developed to inhibit an enzyme (LSD1) known to contribute to tumour growth, and may be used as a future treatment for cancers including myeloid leukemia and myelofibrosis.

Who is it for?
You may be eligible for this study if you are a healthy adult aged 18 to 65 years, have a non-smoker status and have no prior history of relevant drug hypersensitivity. People who have been diagnosed with cancer will not be eligible for this study.

Study details
In this study participants will test two formulations of IMG-7289 with and without food. In each study period, participants will spend 4 nights in clinic followed by 4 follow-up visits. There will be 4 study periods, with one End of Study outpatient visit. There will be a 14-day washout period between doses to ensure there is no IMG-7289 in their body before the next dose. All participants will be asked to undergo blood tests and answer questions regarding their health.

It is hoped that information from this study informs researchers of how the body metabolises IMG-7289 and thus how it may be used to treat bone marrow malignancies, such as myeloid leukemia and myelofibrosis.
