Identification and Characterization of Genetic Variants in Hereditary Angioedema (GENOMAEH_01)

April 17, 2023 updated by: Hospital Universitari Vall d'Hebron Research Institute

Identification and Functional Characterization of Genetic Variants Associated With Specific Clinical Phenotypes in Hereditary Angioedema Due to C1 Inhibitor Deficiency: An Unbiased Approach

This project aims to analyse in an unbiased way the existence of genetic variants that contribute to explaining and predicting the differences in clinical expression between patients with HAE.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

Adult patients with hereditary angioedema with C1INH deficiency (HAE-C1INH) from different regions of Spain will be included. Patients included in the study will be divided into two groups: a) symptomatic (≥ 18 years old), which will be those who present symptoms compatible with HAE-C1INH and who have a confirmed diagnosis and b) asymptomatic patients (≥ 22 years old), which will be those with a C1INH deficiency and who have not developed symptoms of HAE.

Description

Inclusion Criteria:

  • Adult patients (≥ 18 years old) with HAE-C1INH diagnosis (confirmed by mutation in SERPING1 gen or immunochemical study showing a decrease in C1INH function <50% in two determinations together with a family history (symptomatic patients' group)
  • Patients ≥ 22 years old with C1INH hereditary deficiency (confirmed by mutation of SERPING1 gene or immunochemical study showing a decrease in C1INH function <50% in two determinations together with a family history) and who have not developed symptoms consistent with HAE-C1INH
  • Signed informed consent.

Exclusion Criteria:

  • No confirmed C1INH deficiency.
  • Inability to sign the informed consent.
  • Presence of recurrent angioedema with histaminergic characteristics (response to treatment with antihistamines, glucocorticoids and/or epinephrine)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Symptomatic patients
Adult patients (≥ 18 years old) with hereditary angioedema with C1INH deficiency (HAE-C1INH) from different regions of Spain will be included. Patients included in the study will be divided into two groups: a) symptomatic, which will be those who present symptoms compatible with HAE-C1INH and who have a confirmed diagnosis
Asymptomatic patients
Asymptomatic patients, which will be those with a C1INH deficiency and who have not developed symptoms of HAE. Asymptomatic patients must be at least 22 years old and meet the same criteria than those symptomatic, except for the presence of symptoms consistent with HAE-C1INH

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Set of validated disease-modifying genetic variants in Spanish patients with HAE-C1INH
Time Frame: Day 1
To identify and characterize novel genetic variants associated with the incomplete penetrance and variable clinical expressivity observed in HAE-C1INH patients.
Day 1

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2023

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
March 31, 2026

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
