Participants received a matching placebo IV loading dose, followed by 3 SC doses.
Number of Participants With Treatment-emergent (TE) Serious Adverse Events (SAEs)
A TE SAE is defined as an SAE reported at or after the start of the first administration of study treatment. A SAE is defined as any untoward medical occurrence that at any dose results in: death, life-threatening event, initial or prolongation of existing hospitalization, disability or incapacity, congenital anomaly or birth defect, or any other medically significant event.
Time frame: Up to 22 weeks
Percentage of Participants With TE SAEs
A TE SAE is defined as an SAE reported at or after the start of the first administration of study treatment. A SAE is defined as any untoward medical occurrence that at any dose results in: death, life-threatening event, initial or prolongation of existing hospitalization, disability or incapacity, congenital anomaly or birth defect, or any other medically significant event
Time frame: Up to 22 weeks
Number of Participants With TE Adverse Events of Special Interests (AESIs)
The following TEAEs were considered as AESIs: Bleeding events that were abnormal in the opinion of the Investigator, Thromboembolic events (non-systemic thrombosis \[e.g., localized thrombosis associated with vascular access\] was not considered an AESI), and Severe hypersensitivity including anaphylaxis.
Time frame: Up to 22 weeks
Percentage of Participants With TE-AESIs
The following TEAEs were considered as AESIs: Bleeding events that were abnormal in the opinion of the Investigator, Thromboembolic events (non-systemic thrombosis \[e.g., localized thrombosis associated with vascular access\] was not considered an AESI), and Severe hypersensitivity including anaphylaxis.
Time frame: Up to 22 weeks
Number of Participants With Garadacimab Induced Anti Drug Antibodies (ADAs) in Plasma
Time frame: At Day 36 and Day 92 after the first treatment

Mean Change From Baseline in FXIIa-mediated Kallikrein Activity
Time frame: Baseline and at Day 92
Mean Percentage of Baseline in FXIIa-mediated Kallikrein Activity
Percent baseline is calculated by using the formula visit value / baseline value multiplied by 100, percent baseline is reported as percentage in the outcome measure.
Time frame: Baseline and at Day 92
