| Primary | Number of Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) | Number of TEAEs and SAEs is presented. An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. AEs were defined as TEAEs if they had a start date on or after the administration of study drug during the treatment period, or if they occurred prior to the administration of study drug and worsened in severity/grade or relationship to the study intervention after the administration of study intervention during the treatment period. A SAE was defined as any untoward medical occurrence that, at any dose: a) resulted in death, b) is life-threatening, c) required inpatient hospitalization or prolongation of existing hospitalization, d) resulted in persistent disability/incapacity, e) was a congenital anomaly/birth defect. | Safety population included all participants randomly assigned to study intervention and who received at least 1 dose of belcesiran/placebo. | Posted | | Number | | Events | | Up to 2.6 years | | | | ID | Title | Description |
