- Minstens 4 HAE-aanvallen ervaren in de 12 maanden voorafgaand aan de screening, per deelnemersrapport.
- Minstens 2 HAE-aanvallen meegemaakt tijdens de inloopperiode, zoals bevestigd door een onderzoeker op basis van het voldoen aan de in het protocol gespecificeerde definitie van een HAE-aanval.
Uitsluitingscriteria:
- Elke gelijktijdige diagnose van een andere vorm van chronisch angio-oedeem, zoals verworven C1-remmerdeficiëntie, HAE met normale C1-INH (ook bekend als HAE type III), idiopathisch angio-oedeem of angio-oedeem geassocieerd met urticaria.
Gebruik van therapieën die zijn voorgeschreven voor de preventie van HAE-aanvallen voorafgaand aan screening:
- lanadelumab binnen 90 dagen
- berotralstat binnen 21 dagen
- alle andere profylactische therapieën binnen 7 dagen
- Elke blootstelling aan angiotensine-converterende enzymremmers of oestrogeenbevattende medicijnen met systemische absorptie (zoals hormonale anticonceptiva of hormoonvervangende therapie) binnen 28 dagen voorafgaand aan de screening.
- Elke blootstelling aan androgenen (bijvoorbeeld stanozolol, danazol, oxandrolon, methyltestosteron, testosteron) binnen 7 dagen voorafgaand aan de screening.

Number of Participants Experiencing Treatment-emergent Adverse Events
Tijdsspanne: Day 1 through Day 448 (Cohort 1), Day 531 (Cohort 2), Day 475 (Cohort 3)
|
An adverse event was any untoward medical occurrence in a clinical investigation participant who was administered a pharmaceutical product that did not necessarily have a causal relationship with the treatment.
A treatment-emergent adverse event was defined as any adverse event with an onset at the time of or following the start of treatment with study drug, or medical conditions present before the start of treatment that increased in severity or relationship at the time of or following the start of treatment.
A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' section.

Percent Change From Baseline in Monthly Hereditary Angioedema (HAE) Attack Rate
Tijdsspanne: Baseline, Day 168 (Cohort 1), Day 251 (Cohort 2), Day 195 (Cohort 3)
|
An attack was considered an HAE attack if at least 1 of the following criteria was met (per the investigator): peripheral angioedema (cutaneous swelling involving an extremity, the face, neck, torso, and/or genitourinary region); abdominal angioedema (abdominal pain, with or without abdominal distention, nausea, vomiting, or diarrhea); laryngeal angioedema (stridor, dyspnea, difficulty speaking, difficulty swallowing, throat tightening, or swelling of the tongue, palate, uvula, or larynx).
The HAE attack rate was the number of unique investigator-confirmed HAE attacks per month.

|
|
Time to First HAE Attack After First and Last Dosing
Tijdsspanne: Day 1 through Day 168 (Cohort 1), Day 251 (Cohort 2), and Day 195 (Cohort 3)
