Hereditary Angioedema (HAE)
Conditions
Brief summary
The main aim of this study is to compare the number of HAE attacks occuring in persons using lanadelumab with the number of HAE attacks before lanadelumab treatment was started. Data from participants who start the study after 1 March 2021, will be collected for 24 months; data from all other participants (who started the study before 1 March 2021) will be collected for 36 months. Participants will report information in a smartphone application at study start and for the next 3 months and then every 6 months until the study ends; data will also be collected by the study doctor during routine clinic visits

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence Rate Ratio of On-Treatment Participant-Reported Hereditary Angioedema (HAE) Attacks | Up to 36 months | HAE attack is defined as a discrete episode during which the participant progress from no angioedema to symptoms of angioedema. Incidence rate ratio of on-treatment patient-reported HAE attacks up to three years after initiation of lanadelumab compared to the history of HAE attacks of last three months prior to lanadelumab use will be reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Mild, Moderate, Severe Hereditary Angioedema (HAE) Attacks | Up to 36 months | The overall severity of attack is determined using following definitions: mild (Temporary or mild discomfort), moderate (Activity limited mildly or moderately. Some assistance may be needed), severe (Activity considerably limited, assistance needed). |
| Number of On-Treatment Participant-Reported Hereditary Angioedema (HAE) Attacks Based on Anatomical Location | Up to 36 months | Number of on-treatment participant-reported HAE attacks based on anatomical (peripheral, abdominal, laryngeal) location will be assessed. |
| Proportion of Hereditary Angioedema (HAE) Attacks for Which On-Demand Therapy is Used | Up to 36 months | Proportion of HAE attacks for which participants use on-demand therapy will be assessed. |
| Time to First Hereditary Angioedema (HAE) Attack for Which On-Demand Therapy is Used | Up to 36 months | Time to first HAE attack for which on-demand therapy is used will be assessed. |
| Proportion of Hereditary Angioedema (HAE) Attacks Requiring Visit to an Healthcare Provider (HCP), Access to an Emergency Room (ER), or Hospitalization | Up to 36 months | Proportion of HAE Attacks requiring visit to HCP, access to an ER, or hospitalization will be assessed. |
| Angioedema Quality of Life (AE-QoL) | Up to 36 months | The AE-QoL is developed to measure participant-reported health-related quality of life (HRQoL) impairment in participants with recurrent angioedema. It is a self-administered participant related outcome (PRO) with a recall period of 4 weeks. There are 17 items across 4 domains: functioning (4 items), fatigue/mood (5 items), fears/shame (6 items), and food (2 items). Responses use a 5-point Likert scale ranging from 'never' to 'very often.' Global scores range from 0 to 100 and scores by domains range from 0 to 100, where 0 indicates highest quality of life and 100 lowest quality of life. |
| Fatigue Severity Scale (FSS) | Up to 36 months | Participant reported fatigue will be measured by the FSS. The FSS is a 9-item questionnaire measuring participants fatigue severity and its impact on motivation, exercise, physical functioning, and work and social life. It uses a 7-point Likert scale response (1 = strongly disagree, 7 = strongly agree) and the final score is obtained as mean of the response scores to the individual questions. |
| Hospital Anxiety and Depression Scale (HADS) | Up to 36 months | The HADS is a self-rating scale developed to detect the levels of depression and anxiety experienced by participants. It is a self-administered PRO composed of 14 items, of which seven relate to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0 to 3, which means that a person can score between 0 and 21 for either anxiety or depression. Recommended cut-off scores are 8 to 10 for doubtful cases and greater than or equal to (\> or =) 11 for definite cases. |
| Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) | Up to 36 months | The TSQM is a generic questionnaire to measure participants satisfaction with medication using yes/no and 5- or 7-point Likert scale response options. It is a self-administered PRO instrument designed for adults aged 18 years or older with a recall period of two to three weeks, or since the last medication use. Version TSQM-9 includes three domains: effectiveness (three items), convenience (three items), and global satisfaction scale (three items). |
| Work Productivity and Activity Impairment: General Health (WPAI:GH) | Up to 36 months | The WPAI:GH is a generic questionnaire to measure the effect of general health and symptom severity on work productivity and regular activities during the past seven days. It can be self or interviewer-administered to adults aged 18 years or older. This six-item PRO instrument covers work (five items) and daily activities (one item) using yes/no or numerical answers (number of hours). |
| Rate of On-Treatment Participant-Reported Hereditary Angioedema (HAE) Attacks From Day 70 | From Day 70 up to 36 months | Rate of participant-reported HAE attacks during treatment with lanadelumab from day 70 will be assessed. |
| Dose of Lanadelumab | From start of the study up to 36 months | Dose of lanadelumab used during the study will be assessed. |
| Frequency of Administration of Lanadelumab | From start of the study up to 36 months | Frequency of lanadelumab injections during the study will be assessed. |
| Participants' Adherence Rate to Treatment with Lanadelumab | Up to 36 months | Adherence is defined as the proportion of time on treatment over the study observation time period, times the proportion of actual lanadelumab doses taken per label as reported by participants through an administration diary over the total expected lanadelumab doses per label during the treatment period. |
| Frequency of Use of Approved Lanadelumab Dosing Regimens | Up to 36 months | Frequency of use of approved lanadelumab dosing regimens will be assessed. |
| Frequency of Administration Modalities of Lanadelumab | Up to 36 months | Frequency of administration modalities of lanadelumab (self-administration versus (vs). administration by a caregiver, HCP, or other) will be assessed. |
| Number of Administrations of Lanadelumab Before Participant Discontinuation | Up to 36 months | Number of administrations of lanadelumab before participant discontinuation from the study will be assessed. |
| Frequency of Reasons for Discontinuation of Treatment With Lanadelumab Reported by Participants | Up to 36 months | Frequency of reasons for discontinuation of treatment with lanadelumab reported by participants will be assessed. |
| Adverse Event (AE) Incidence, Type, Seriousness and Relatedness to Lanadelumab Treatment | From start of the study up to 36 months | An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (study) product whether or not related to the medicinal product. AE incidence, type, seriousness and relatedness to lanadelumab treatment will be assessed. |
| Severity of Non-Serious Adverse Events (AEs) | From start of the study up to 36 months | Severity of AEs is determined by using the following definitions: Mild: A type of AE that is usually transient and may require only minimal treatment or therapeutic intervention, the event does not generally interfere with activities of daily living. Moderate: A type of AE that is usually alleviated with specific therapeutic intervention, the event interferes with usual activities of daily living, causing discomfort, but poses no significant or permanent risk of harm to the research participant. Severe: A type of AE that interrupts usual activities of daily living (ADL), or significantly affects clinical status, or may require intensive therapeutic intervention. Severity of non-serious AEs will be assessed. |
| Adult Carer Quality of Life (AC-QoL) Questionnaire | Up to 36 months | The AC-QoL is a 40-item tool that measures the overall QoL for adult carers, and subscale scores for eight domains of QoL: support for caring, caring choice, caring stress, money matters; personal growth; sense of value, ability to care, and carer satisfaction. It is self-administered to adult carers and should take no longer than 10 minutes to complete. Scores range from 0 to 120, with higher scores indicating greater QoL. |
