Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to assess safety, tolerability, and PK of single ascending doses (SAD) of ABI-4334 in Part A and multiple-ascending doses (MAD) of ABI-4334 in Part B in healthy subjects. Effect of food will also be evaluated in Part A.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Part A: SAD Cohorts 1-5 ABI-4334 Tablet

A single dose of ABI-4334 will be administered on Day 1 in dose-escalation cohorts with a starting dose of 30 mg. The doses for subsequent cohorts will be determined by evaluation of safety and PK data from previous cohorts.

Part A: SAD Fed Cohorts 6-7 ABI-4334 Tablet

A single dose of ABI-4334 will be administered after a high-fat meal on Day 1 in cohort 6. A single dose of ABI-4334 will be administered on two separate occasions, once fasted and once after a high-fat meal in cohort 7. The dose administered will be determined after evaluation of cumulative safety and PK data from cohorts 1-5.
