Secondary Outcome Measures

Name	Time	Method
Number of Participants With Clinically Significant Change in Clinical Laboratory Results Reported as an Adverse Event	From start of study drug administration up to follow-up (up to 115 days)	Clinical laboratory assessments include hematology, clinical chemistry, coagulation and urinalysis. The investigator will assess out-of-range clinical laboratory values for clinical significance, to indicate whether or not the values are clinically significant. Any changes from baseline in clinical laboratory results which are deemed clinically significant by the investigator are to be recorded as an AE.
Number of Participants With Clinically Significant Change in Vital Signs Reported as an Adverse Event	From start of study drug administration up to follow-up (up to 115 days)	Vital sign assessments include blood pressure, pulse rate and body temperature. Any changes from baseline in vital signs which are deemed clinically significant by the investigator are to be recorded as an AE.
Number of Participants Who Developed Antidrug Antibodies to Lanadelumab at Specified Time Points	Day 1, 14, 28, 56, and 112 (End of Study/Early Termination [EOS/ET])	Plasma samples were analyzed for presence of antidrug antibodies to lanadelumab. Participants who show positive results for lanadelumab antibodies were reported.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) Based on Severity, Seriousness and Causality	From start of study drug administration up to follow-up (up to 115 days)	An adverse event (AE) is any untoward medical occurrence in a clinical investigation participants administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. TEAEs are defined as AEs with onset at the time of or following the first exposure to study drug, or medical conditions present prior to the start of study drug but increasing in severity or relationship at the time of or following the start of treatment, up to the last follow-up visit. Severity of an AE is determined by following definitions: Mild: An event that does not generally interfere with usual activities of daily living; Moderate: An event that interferes with usual activities of daily living, causing discomfort but poses no significant or permanent risk of harm to the research participants; Severe: An AE that interrupts usual activities of daily living, or significantly affects clinical status, or may require intensive therapeutic intervention.
Number of Participants With Clinically Significant Change in Electrocardiogram (ECG) Reported as an Adverse Event	From start of study drug administration up to follow-up (up to 115 days)	Twelve-lead ECG will be performed after 5 minutes of rest in the supine position. Any change in ECG assessments which are deemed clinically significant by the investigator are to be reported as AE.
