Safety
ADVERSE EVENT, EVENT
Adverse events (AEs), infusion-related reactions, physical examination, vital signs, 12-lead ECG, and immunogenicity were all evaluated for safety. The severity of the AEs was graded according to Common Terminology Criteria for AE (CTCAE). A treatment-emergent AE (TEAE) was defined as any event that occurred after the study drug was administered but was not present prior to administering the study drug.
