Inclusion Criteria

Each patient must meet the following criteria to be enrolled in this study.

• The patient is ≥18 years old at the time of informed consent.

• The current HAE attack must be in the cutaneous, abdominal and/or laryngeal (inclusive of laryngeal and pharyngeal) areas.
• Cutaneous or abdominal HAE attacks must be moderate to very severe as determined by investigator global assessment at pre-treatment assessments
• The patient must report at least 1 VAS score ≥ 30mm
• The patient commences treatment within 6 hours of the attack becoming at least mild (laryngeal) or moderate (non-laryngeal) in severity, but not more than 12 hours after the onset of the attack.
• Women of childbearing potential must have a negative urine pregnancy test and must use appropriate methods to prevent pregnancy during their participation in the study.

• The patient has received treatment with any pain medication since the onset of the current angioedema attack.
• The patient has received replacement therapy (fresh frozen plasma [FFP], C1-INH products) less than 5 days (120 hours) from the onset of the current angioedema attack.
