A Study to Evaluate the Safety, Tolerability, Pharmacokinetics (PK), and Immunogenicity of APG777 in Adults With Asthma

Purpose

This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, PK, and immunogenicity of APG777 in adult participants with mild-to-moderate asthma. The duration of the study will be approximately 52 weeks (364 days) for each participant and will consist of a Screening Period, Treatment Period, and Follow-up Period.
