Outcome

Type	Measure	Description	Time frame	Safety issue
Other	HAE Attack Rate Per Week From Day 8 to Day 50	Analysis of this outcome measure was based on participants in the 300 mg, 400 mg, and placebo dose groups with a historical baseline attack rate of at least 2 attacks over the last 3 months prior to enrollment. The result is based on General Estimating Equation (GEE) analysis of repeated counts per week during the pre-specified assessment period (Days 8 to 50; predicted to correspond to a period of notable drug exposure). Baseline HAE attack rate per week was a covariate, treatment group is a fixed effect, and participant was a random effect in the GEE model with independence working correlation structure.	Day 8 to Day 50
Other	HAE Attacks Per Week From Day 8 to Day 92	This endpoint analysis was based on participants in the 300 mg, 400 mg, and placebo dose groups with a historical baseline attack rate of at least 2 attacks over the last 3 months prior to enrollment. The result is based on General Estimating Equation (GEE) analysis of repeated counts per week during the prespecified assessment period (Day 8 to Day 92 predicted to correspond to a period of notable drug exposure). Baseline HAE attack rate per week is a covariate, treatment group is a fixed effect, and participant is a random effect in the GEE model with independence working correlation structure.	Day 8 to Day 92
Other	HAE Attacks Per Week From Day 8 to Day 64	This endpoint analysis was based on participants in the 300 mg, 400 mg, and placebo dose groups with a historical baseline attack rate of at least 2 attacks over the last 3 months prior to enrollment. The result is based on General Estimating Equation (GEE) analysis of repeated counts per week during the prespecified assessment period (Day 8 to Day 64 predicted to correspond to a period of notable drug exposure). Baseline HAE attack rate per week is a covariate, treatment group is a fixed effect, and participant is a random effect in the GEE model with independence working correlation structure.	Day 8 to Day 64
Other	HAE Attack Rate Per Week From Day 1 to Day 50	This endpoint analysis was based on participants in the 300 mg, 400 mg, and placebo dose groups with a historical baseline attack rate of at least 2 attacks over the last 3 months prior to enrollment. The result is based on General Estimating Equation (GEE) analysis of repeated counts per week during the prespecified assessment period (Day 1 to Day 50 predicted to correspond to a period of notable drug exposure). Baseline HAE attack rate per week is a covariate, treatment group is a fixed effect, and participant is a random effect in the GEE model with independence working correlation structure.	Day 1 to Day 50
Primary	Number of Participants With Serious Adverse Events (SAE) and Treatment-Emergent Adverse Events (TEAE)	A SAE was any adverse experience occurring at any dose that resulted in any of the following outcomes: Death, Life-threatening experience, required inpatient hospitalization or prolongation of existing hospitalization. Resulted in persistent or significant disability or incapacity. Was a congenital anomaly or birth defect. Was considered to be an important medical event. An AE was considered treatment-emergent if the onset time was after administration of study drug through the Day 120 post-dose final follow-up visit or, in the event that onset time preceded study drug administration, the AE increased in severity during the 120-day post-dose follow-up period.	From Day 1 up to final follow-up (Day 123)
Secondary	Maximum Plasma Concentration (Cmax)	Pharmacokinetic (PK) parameter Cmax data were reported.	Days 1, 2, 4, 8, 15, 16, 18, 22, 29, 36, 50, 64, 92, and 120
Secondary	Time to Maximum Plasma Concentration (Tmax)	PK parameter Tmax data were reported.	Days 1, 2, 4, 8, 15, 16, 18, 22, 29, 36, 50, 64, 92, and 120
Secondary	Area Under the Plasma Concentration-Time Curve (AUC)	PK paramenter AUC data were reported.	Days 1, 2, 4, 8, 15, 16, 18, 22, 29, 36, 50, 64, 92, and 120
