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 pharmacokinetics (PK) of single ascending dose (SAD) of ABI-1179 in Part A in healthy participants and multiple-ascending doses (MAD) of ABI-1179 in Part B in participants seropositive for Herpes Simplex Virus Type 2 (HSV-2) with recurrent genital herpes. Effect of food will also be evaluated in Part A.
