Active clinical trials for "Angioedemas, Hereditary"

Hereditary angioedema (HAE) is a rare genetic disease, it can occur at any age and evolves in flare-ups. These are subcutaneous or submucosal edemas responsible for tightness and pain. All areas can be reached. In addition, all their life, patients have an unpredictable risk of death from asphyxiating angioedema (25% mortality in the absence of specific treatment). Surgical procedures, endoscopies and dental procedures can trigger laryngeal AE. Thus, the national reference center for angioedema (CREAK) and the latest international consensus1 recommend that all these procedures be preceded by short-term prophylaxis. The reference treatment is the C1 inhibitor 2 concentrate. But to date, there is no prospective study that has demonstrated the effectiveness of this short-term prophylaxis before dental treatment. Only a retrospective study has shown that its implementation made it possible to reduce the risk of crisis by 42% after tooth extraction 3 and that the risk of crisis was greatest within 8 hours following tooth extraction. The C1 inhibitor concentrate must be administered IVL by a nurse within 6 hours before the procedure and therefore implies, in addition to its high cost (1500 €), an organizational burden for the patient who must plan for the passage of an IDE, the availability of the product and this sometimes for a simple dental treatment. These constraints have two consequences for dental care: patients avoid going to the dentist to the detriment of their dental health or do not take prophylaxis with the risk of a fatal attack.

This study is a survey in Japan of Icatibant subcutaneous injection 30 mg syringe used to treat children or teenagers with acute attacks of hereditary angioedema (HAE). The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects related from Icatibant subcutaneous injection 30 mg syringe and to check if Icatibant subcutaneous injection 30 mg syringe improves acute attacks of HAE. During the study, pediatric participants with HAE will take Icatibant subcutaneous injection 30mg syringe according to their clinic's standard practice. The study doctors will check for side effects from Icatibant subcutaneous injection 30 mg syringe for 3 months.

This study is a survey in Japan of Lanadelumab used to treat people with hereditary angioedema (HAE). The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects related from Lanadelumab and to check if Lanadelumab improves symptoms of HAE. During the study, participants with HAE will take Lanadelumab subcutaneous injection according to their clinic's standard practice. The study doctors will check for side effects from Lanadelumab for 12 months.

This is a phase 3b open-label study providing access to berotralstat for HAE patients who were previously enrolled in berotralstat studies.

This study evaluates the safety and efficacy of PHA-022121 administered orally for prophylaxis against angioedema attacks in patients with hereditary angioedema (HAE). The study consists of 2 parts, with patients completing participation in Part 1 prior to initiation of treatment in Part 2. Part 1 of the study has 3 parallel arms and approximately 30 patients will be equally randomized to one of two dose regimens of PHA-022121 or matching placebo. Patients will continue to the single open-label arm in Part 2 of the study after completion of Part 1. The screening period is up to 8 weeks and the treatment periods are 12 weeks (Part 1) and 30 months (Part 2) in duration.

This phase 3b study will evaluate long-term safety and efficacy of CSL312 (also known as garadacimab) when administered subcutaneously (SC)

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.

The main aim of this study is to describe the treatment patterns, characteristics and outcomes of people with HAE who are currently receiving icatibant in the homecare setting in the United Kingdom (UK). Participants will be treated with icatibant according to their routine practice via homecare service for icatibant within the UK. Data will be directly collected from participants via study diaries and questionnaires. Participants will be contacted approximately every 90 days during study duration (this can occur via phone or as a face-to-face visit).

The main aim of this study is to learn about how many persons with HAE type I or type II are attack-free when treated with lanadelumab in real life, how many attacks occur and how many of these attacks need rescue treatment and about the nature of HAE attacks. Participants will need to visit their doctor 5 times in total as part of this study. The visits are planned every 6 months. Participants will also be asked to fill out questionnaires as part of this study.

The objectives of this survey are to collect data to report the safety and efficacy of Firazyr (Icatibant acetate) in the post-marketing phase in participants diagnosed with Hereditary Angioedema (HAE).
