Brief Summary:
A multicenter epidemiological observational study aiming to explore the cleaved high-molecular weight kininogen (cHMWK) including identification and characterization of other metabolite/biomarkers in HAE type 1/2 patients

Condition or disease
Hereditary Angioedema

Detailed Description:

Hereditary angioedema (HAE) is a rare autosomal dominant genetic disorder characterized by recurrent tissue angioedema episodes, mainly caused by mutations in the SERPING1 gene that encodes C1 inhibitor (C1-INH), a protease involved in limiting bradykinin production. Low levels of C1-INH (HAE type 1) or dysfunctional C1-INH (HAE type 2) lead to bradykinin accumulation, resulting in capillary leakage and tissue swelling.

High Molecular Weight Kininogen (HMWK) proteolysis, by active plasma kallikrein, results in bradykinin and cHMWK generation.

The goal of this study is to explore the cHMWK concentrations in HAE type 1/2 patients, as a biomarker for this disease.

The HAEKA study is performed in collaboration with Shire. Shire is a wholly owned subsidiary of Takeda Pharmaceutical Company Limited.

Group/Cohort
Participants with Hereditary Angioedema
Participants older than 18 years that are clinically diagnosed with Hereditary Angioedema type 1/2 and experienced ≥4 HAE attacks within last 12 month before the enrollment



Primary Outcome Measures :
  1. Exploring the cleaved high-molecular weight kininogen (cHMWK) as a biomarker in HAE type 1/2 patients, as well as to study the differences between HAE type 1/2 patients without lanadelumab treatment versus patients on lanadelumab treatment. [ Time Frame: 30 months ]
    Samples from HAE patients without lanadelumab treatment versus patients on lanadelumab treatment will be analyzed for cHMWK via Liquid Chromatography Multiple Reaction-monitoring Mass Spectrometry (LC/MRM-MS).


Secondary Outcome Measures :
  1. Studying cHMWK as a biomarker in HAE type 1/2 patients with edema attack, as well as to study the differences between HAE type 1/2 patients without lanadelumab treatment versus patients on lanadelumab treatment. [ Time Frame: 30 months ]
    Samples from HAE patients without lanadelumab treatment versus patients on lanadelumab treatment collected before/during/after angioedema attacks will be analyzed for cHMWK via Liquid Chromatography Multiple Reaction-monitoring Mass Spectrometry (LC/MRM-MS).


Other Outcome Measures:
  1. Studying other metabolites as potential biomakers in HAE type 1/2 patients, as well as to study the differences between HAE type 1/2 patients without lanadelumab treatment versus patients on lanadelumab treatment. [ Time Frame: 30 months ]
    All samples will be analyzed for potential biomarker candidates via Liquid Chromatography Multiple Reaction-monitoring Mass Spectrometry (LC/MRM-MS).
