Study Endpoints

Primary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs) Possibly or Probably Related to Treatment
NHV participants: up to Day 29 (± 2 days); CHB participants: Day 113 (± 2 days)

An adverse event (AE) is any untoward medical occurrence which does not necessarily have to have a causal relationship with this treatment. TEAEs were defined as AEs with onset after administration of the study drug, or when a preexisting medical condition increases in severity or frequency after study drug administration. Assessment of causality utilized 3 possible categories: not related, possibly related and probably related.

Secondary Endpoints
