Clinical Trial Summary

This study is about teenagers and adults with hereditary angioedema (HAE) type I and type II. In this study, the burden of illness means the impact of HAE in terms of long-term health outcomes and the financial cost. The main aims of this study are as follows: - to learn how often, how severe and where on the body HAE attacks occur. - to describe how HAE prophylaxis and on-demand medicines are prescribed and used. (Prophylaxis medicines prevent a bleed from happening and on-demand medicines treat a bleed when it occurs.) This study is about collecting data only; participants will not receive treatment as part of this study. Existing data available in the participant's medical records will be collected. Participants will be asked to complete an electronic questionnaire either on a website or by using an app on their mobile phone; data from this questionnaire will also be collected. Participants do not need to visit their doctor in addition to their normal visits.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With HAE Attacks Occurrence During Study Period	HAE attack is defined as the symptoms or signs consistent with an attack in at least 1 of the following locations: 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). Number of participants with HAE attacks occurrence (start and end date of each HAE attack) during study period will be reported.	Throughout the study period (up to 6 months)
Primary	Number of Participants Categorized Based on Characteristics of HAE Attacks During Study Period	HAE attack characteristics will be based on prodromal symptoms, severity and location, whether attack was life-threatening will be reported.	Throughout the study period (up to 6 months)
Primary	Time Interval Between HAE Attacks During Study Period	Time interval between HAE attacks during the study period will be reported.	Throughout the study period (up to 6 months)

Secondary	Health-related Quality of Life (HRQoL): Angioedema Quality of Life (AE-QoL) Questionnaire	The AE-QoL was developed to measure HRQoL in participants with recurrent angioedema. It is a self-administered patient-reported outcome instrument with a recall period of four weeks. There are 17 items across four domains: functioning (four items), fatigue/mood (five items), fears/shame (six items), and food (two items). Responses use a 5-point Likert scale ranging from 1 (Never) to 5 (Very Often). Global scores range from 0 to 100 and scores by domains range from 0 to 100. An overall score is calculated and a higher score indicates lower quality of life.	Throughout the study period (up to 6 months)
Secondary	HRQoL: EuroQoL Group 5-Dimension 5-Level (EQ-5D-5L) Questionnaire	The EQ-5D-5L descriptive system assesses health in five dimensions (Mobility, Self-Care, Usual Activities, Pain / Discomfort, Anxiety / Depression), each of which has five levels of response (no problems, slight problems, moderate problems, severe problems, extreme problems/unable to). This part of the EQ-5D questionnaire provides a descriptive profile that can be used to generate a health state profile. Health state index scores generally range from less than 0 (where 0 is the value of a health state equivalent to dead; negative values representing values as worse than dead) to 1 (the value of full health), with higher scores indicating higher health utility. The second part of the questionnaire consists of a visual analogue scale (VAS) on which the participant rates his/her perceived health from 0 (the worst imaginable health) to 100 (the best imaginable health).	Throughout the study period (up to 6 months)
Secondary	HRQoL: EuroQoL-five Dimensions, Youth Version (EQ-5D-Y)	The EQ-5D-Y is composed of two sections. The first section contains one question for each of the five dimensions: mobility, looking after myself, doing usual activities, having pain or discomfort, and feeling worried, sad, or unhappy. Participants select from three response levels (no problems, some problems, a lot of problems) for each dimension. A health state profile score can be calculated from the responses on these five questions. The second section includes the same visual analogue scale as the EQ-5D-5L. The scale is scored from 0-100. The reference to a high score indicates a better outcome of quality of life.	Throughout the study period (up to 6 months)
Secondary	Number of Participants With HAE Attacks Occurrence in Relevant Subgroups	HAE attack is defined as the symptoms or signs consistent with an attack in at least 1 of the following locations: 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). Relevant subgroups is defined by disease characteristics (e.g., number of attacks) and treatment patterns (type of treatments for HAE). Number of participants with HAE attacks occurrence (start and end date of each HAE attack) in relevant subgroups will be reported.	Throughout the study period (up to 6 months)
Secondary	Number of Participants Categorized Based on Characteristics of HAE Attacks in Relevant Subgroups	HAE attack characteristics will be based on prodromal symptoms, severity and location, whether attack was life-threatening in relevant subgroups will be reported. Relevant subgroups is defined by disease characteristics (e.g., number of attacks) and treatment patterns (type of treatments for HAE).	Throughout the study period (up to 6 months)

Relevant subgroups is defined by disease characteristics (e.g., number of attacks) and treatment patterns (type of treatments for HAE).	Throughout the study period (up to 6 months)
Secondary	Duration of Each HAE Attacks in Relevant Subgroups	Duration of each HAE attacks in relevant subgroups will be reported. Relevant subgroups is defined by disease characteristics (e.g., number of attacks) and treatment patterns (type of treatments for HAE).	Throughout the study period (up to 6 months)
