About this study

Official title: Treatment and Outcomes of Patients Identified With Non-Histaminergic Angioedema With Normal C1 Inhibitor in Canada

The main aim of this study is to describe the characteristics of participants, check for number of hereditary angioedema (HAE) cases, their treatment and outcomes. Another aim is to check how the healthcare facilities were utilized for treatment.

Participants' data will be taken from their medical records (charts), which were already collected as a part of their routine care between January 1, 2012, and January 1, 2022.

Read the detailed description

This is a non-interventional, retrospective, observational study of participants with Hereditary Angioedema with normal C1 esterase inhibitor (HAE) and Non-histaminergic Angioedema (NHAE) with normal C1-inhibitor function (nC1-INH) receiving various treatments between January 1, 2012, and January 1, 2022. The study will assess case numbers, treatments, outcomes, and healthcare resource utilization in the real-world setting.

This study will enroll approximately 90 to 150 participants. Participants will be enrolled in the following two cohorts:

  • Participants with HAE nC1-INH
  • Participants with NHAE nC1-INH

This study will have a retrospective data collection from January 1, 2012 to January 1, 2022 by using data from the participant medical charts that were already collected as part of routine care.

This multi-center trial will be conducted in Canada. The overall time for data collection in this study will be approximately 10 years.

Questions about this trial

What is this clinical trial studying?

An observational study of Hereditary Angioedema (HAE) and Angioedema, run by Takeda at 6 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Diagnosed With HAE nC1-INH at Each Site (time frame: Up to approximately 10 years). The study lists 19 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2024.
