Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AJM347 in Healthy Male Caucasian and Japanese Subjects in the Fasted and Fed State

Study Overview
=================
Brief Summary
-----------------
This study will be conducted to determine the safety and tolerability of single and multiple oral ascending doses of AJM347 in healthy male participants, and to assess the pharmacodynamic response following single and multiple oral ascending doses of AJM347 in the same population. This study will also aim to determine the single and multiple oral ascending dose pharmacokinetics of AJM347 and its metabolite in healthy male participants, and to determine the effect of food on the single and multiple oral dose pharmacokinetics of AJM347 and its metabolite in the same population.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Part 1: AJM347<br>Caucasian and Japanese participants will be randomized to receive one of eight and four single oral doses of AJM347, respectively, administered in the fasted state on Day 1. | Drug: AJM347<br>* Oral administration<br>|
| Placebo Comparator: Part 1: Placebo<br>Caucasian and Japanese participants will be randomized to receive one of eight and four single oral doses of matching placebo, respectively, administered in the fasted state on Day 1. | Drug: Placebo<br>* Oral administration<br>|
| Experimental: Part 2: Low-dose AJM347<br>Caucasian and Japanese participants will receive a low dose of AJM347 (at different frequencies and in either a fed or fasted state) on Day 1 of each of 6 sequential treatment periods. | Drug: AJM347<br>* Oral administration<br>|
| Experimental: Part 2: High-dose AJM347<br>Caucasian and Japanese participants will receive a high dose of AJM347 (at different frequencies and in either a fed or fasted state) on Day 1 of each of 2 sequential treatment periods (the frequency and timing with respect to meals will be determined after review of the data from the low-dose AJM347 groups). | Drug: AJM347<br>* Oral administration<br>|
| Experimental: Part 3: AJM347<br>Caucasian and Japanese participants will be randomized to receive one of three single doses of AJM347 on the morning of Day 1 and multiple daily doses beginning on the morning of Day 3, with the last dose received on the evening of Day 9. The actual doses, dosing frequencies, and timings with respect to meals to be employed in Part 3 of the study will be determined after review of the data from dose groups in Parts 1 and 2 of the study. | Drug: AJM347<br>* Oral administration<br>|
| Placebo Comparator: Part 3: Placebo<br>Caucasian and Japanese participants will be randomized to receive one of three single doses of matching placebo on the morning of Day 1 and multiple daily doses beginning on the morning of Day 3, with the last dose received on the evening of Day 9. The actual doses, dosing frequencies, and timings with respect to meals to be employed in Part 3 of the study will be determined after review of the data from dose groups in Parts 1 and 2 of the study. | Drug: Placebo<br>* Oral administration<br>|
