DEpth of EPinephrine Delivery With Auto-injectors Devices

Study Purpose

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Although there are several causes of fatal anaphylaxis, food allergy is one of the most common. Epinephrine is recommended as the initial treatment of choice for anaphylaxis. A delay in epinephrine administration may contribute to an increased risk of death. Therefore, the World Allergy Organization recommends that, for the treatment of anaphylaxis, epinephrine solution be administered intramuscularly in the mid-anterolateral thigh. In France 3 auto-injector pens are available: Anapen®, Epipen® and Jext®. For weight> 30 kg, the devices have a needle size respectively of 7.49 mm, 15.02 mm and 15.36 mm. For the weights between 15 and 30 kg needle size is 7.49 mm to 12.7 mm and Anapen® for Epipen® and Jext®. Several studies suggest that the needle length needle is sometim

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.
