Design outcomes

Primary

MeasureTime frame
Incidence of treatment-emergent adverse events measured using patient records at first dosing visit through final follow-up visit

Secondary

MeasureTime frame
First dosing visit through final follow-up visit measured using patient records: 1. Number of time-normalized investigator-confirmed HAE attacks 2. Number of moderate or severe investigator-confirmed HAE attacks 3. Number of investigator-confirmed HAE attacks that require on-demand treatment 4. Percent reduction in monthly investigator-confirmed HAE attacks 5. Time to first investigator-confirmed HAE attack after first dose 6. The number of participants responding to treatment, defined as a = 50%, = 70%, or = 90% reduction in investigator-confirmed HAE attack rate 7.
