Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will evaluate single ascending doses (SAD) of APG333 administered subcutaneously (SC) in healthy participants. In each of 4 treatment cohorts (maximum), 8 participants will be randomized 6:2 to APG333 or placebo (up to 32 participants total).

Cohort 1 - APG333 Dose 125 milligram (mg) or placebo
Cohort 2 - APG333 Dose 250 mg or placebo
Cohort 3 - APG333 Dose 500 mg or placebo
Cohort 4 - APG333 Dose 1000 mg or placebo

The study will be conducted in Australia. The anticipated duration of the study is up to approximately 267 days, including screening and safety follow-up.
