NCT05469789

Brief Summary

The main aim of this study is to compare the HAE attacks (both total and those requiring on-demand treatment) in the 12 months before and up to 24 months after initiation of treatment with lanadelumab. This study is conducted in the United Kingdom where participants were treated or about to be treated with landelumab according to their routine practice at hospitals. Data will be directly collected from participants via study diaries, questionnaires, their medical records, and study doctors treating them. Participants will be contacted every 3 months during study participation (via phone).

Outcome Measures

Primary Outcomes (1)

  • Number of Hereditary Angioedema (HAE) Attacks

    Number of HAE attacks (both total \[including untreated\] and those requiring on-demand treatment) will be estimated across the pre- and post-treatment periods (that is, 12 months before and up to 24 months after initiation of treatment with lanadelumab).

    Up to approximately 3 years

Secondary Outcomes (16)

  • Number of Participants Categorized by Their Demographic Characteristics

    At index (lanadelumab treatment initiation day)

  • Number of Participants Categorized by Their Clinical Characteristics

    Up to approximately 3 years

  • Number of Participants Categorized by Their Treatment Patterns

    At and after index (lanadelumab treatment initiation day plus approximately 2 years)

  • Number of Participants Categorized by Their Patterns of Prophylactic Treatment

    Up to approximately 3 years

  • Compare the Number of Participants Categorized by Their Clinical Features of HAE Attacks Before and After Initiation of Lanadelumab

    Up to approximately 3 years

  • +11 more secondary outcomes

Study Arms (3)

Prevalent Cohort A

Prevalent Cohort A will comprise eligible participants with HAE type I or II who have initiated treatment with lanadelumab at any point in time (i.e., all prevalent cases of exposure to lanadelumab). The total follow-up encompasses a 12-month pre-treatment period, and an up-to 24-month post-treatment period.

Other: No Intervention

Prevalent Cohort B

Prevalent Cohort B will comprise eligible participants with HAE type I or II who have been treated with lanadelumab for \<12 months (i.e., the subset of participants from Prevalent Cohort A who initiated treatment with lanadelumab within \<12 months). The total follow-up encompasses a 12-month pre-treatment and an up to 24-month post-treatment period, as well as a prospective data collection period of participant-specific duration.

Other: No Intervention

Incident Cohort A

Incident Cohort A will comprise eligible participants with HAE type I or II initiating treatment with lanadelumab at any time within the prospective data collection time period. The total follow-up encompasses a 12-month pre-treatment and an up-to 24-month post-treatment period, as well as a prospective data collection period of participant-specific duration.

Other: No Intervention

As it is an observational study, no intervention is administered in this study.
