Acquisition and Long-term Observation of Patients With Severe Allergic Reactions

Study Purpose

The Anaphylaxis Registry aims to assess data in a standardized form about symptoms, triggers, cofactors and therapy management from patients who experienced an anaphylactic reaction. This should improve diagnosis and long-term management of these life-threatening allergic reactions.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

A better understanding of the triggers and pathology of anaphylactic reactions could lead to a better diagnosis and prophylaxis to avoid the occurence of these life-threatening allergic reactions. This can be an advantage for affected persons regarding the their treatment and long-term management. The Anaphylaxis Registry is an opportunity to gather these standardized data. The blood sampling is optional for the patient, however, it will contribute to the better understanding of the sensitization profile and possible mechanisms. Recent publications showed a correlation between an anaphylactic reaction and certain biomarkers. Those data will be validated in a larger number of population with identification of further biomarkers. It is presumed that certain genetic and epigenetic polymorphisms are abundant for patients who experienced an anaphylaxis. To summarize, this study aims to contribute to a better understanding of the anaphylaxis in general, the diagnosis, and the prognosis with different severities. With the identification of a certain trigger, the obtained understanding may help to decrease the risk of or prevent future repeating reactions.
