Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be confined at the site during the dosing period where dosing will be done via direct supervision and they can only participate in one of the following cohorts:
- Part 1 cohorts 1, 2, 4, 5 (oral capsule): Screening/ baseline period of up to 28 days with total duration up to 42 days. Single ascending doses of AXN-027 Salt between 100 mg and 1200 mg or placebo (Day 1) administered under fasting conditions. Increases will be based on safety and tolerability at each dose level.
-Part 1 cohort 3: (oral capsule and tablets): Screening/baseline period of up to 28 days with total duration up to 56 days. Three single doses of AXN-027 Salt between 100 mg and 1200 mg or placebo (one capsule and two tablets) administered either fasted or with a high fat, high calorie meal with a 7-day washout between each dose. According to FDA guidance, 'high fat' is an 800-1000 calorie meal with 60% of the calories from fat. An example of a high fat meal is two eggs fried in butter, two strips of bacon, two slices of toast with butter, four ounces of hash brown potatoes and eight ounces of whole milk - with the whole meal containing approximately 60% fat.
Part 1 cohort 6 (oral capsule): Screening/ baseline period of up to 28 days with total duration up to 42 days. Single doses of AXN-027 Salt between 100 mg and 1200 mg (Day 1) administered under fasting conditions .
- Part 2 (oral tablet): screening/ baseline period of up to 28 days with total duration up to 51 days. Twice daily doses of up to 600 mg AXN-027 Salt or placebo (Day 1-7 or Day 1-10) administered under fasting conditions
Exact dose of AXN-027 Salt for Part 1 cohorts 2-6 and Part 2 will be based on safety, tolerability and PK data from initial cohorts of Part 1. After all participants in a cohort are discharged from the site, a safety review committee (SRC) will determine if the next dose level cohort will be initiated. Each consecutive cohort will start approximately 2 weeks after the previous cohort are discharged from the site. Adherence to dosing will be assessed by direct observation of dosing at the site and site direct provision of dose for each timepoint.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All study participants who sign consent will receive a unique sequential number (i.e., a screening number).
Participants who meet the study eligibility criteria will be assigned a randomization number at check-in or predose on Day 1, which corresponds to a study treatment (AXN-027 Salt or placebo).
A sealed envelope containing the study drug assignment for each participant will be provided to the Investigator and kept in a secure location.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)

Summary
Brief summary
This study in healthy volunteers aims to identify the range of safe single and multiple doses of AXN-027 Salt administered by mouth; to assess how the body handles AXN-027 Salt; how AXN-027 Salt contained in capsules compares to AXN-027 Salt contained in a tablet, what effect a high fat meal has on how the body handles AXN-027 absorption and to evaluate the safety of AXN-027 Salt compared to placebo. The results of this study will help identify appropriate doses of AXN-027 Salt to evaluate in future clinical trials.
