Outcome

Type
SECONDARY
Title
China - DBT Period: Number of Participants With Injection-Site Reactions
Description
An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product or other protocol-imposed intervention, regardless of attribution. Local injection reactions (or injection site reactions) are defined as AEs related to the injection site that occur during or within 24 hours after study drug administration that are judged to be related to the study drug injection.
Time frame
From Day 1 up to 14 weeks after the last dose of blinded study drug (up to 124 weeks)
Population
SE analysis set (China) included all participants enrolled in China in the China extension phase who received at least one dose of study drug.
