Predicting Peanut Anaphylaxis and Reducing Epinephrine

Study Purpose

This research study is testing a new way to look for the early stages of anaphylaxis. Eligible participants will have a small monitor (transepidermal water loss) placed on the forearm during a food challenge (for peanut allergies). This monitor continuously records the amount of water lost through the skin. In a previous study the team learned what values are associated with an anaphylactic reaction. These values are called "stopping rules." This study is looking at whether it can use these new stopping rules to end the oral food challenge before a person may show any symptoms.

Recruitment Criteria

Accepts Healthy Volunteers

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

No
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.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Have a known history of food anaphylaxis to peanut confirmed by an allergist.
  • - Have had skin and blood food allergy testing to peanut within the past 12 months.
Meet the 80% likelihood positive predictive value threshold for peanut allergy based on at least 1 of either the skin or blood immunoglobulin E (IgE) tests per current literature corrected for age.
  • - Meet all clinical oral food challenge (OFC) requirements.
This includes no asthma or atopic dermatitis exacerbations, no recent viral infections, no recent antibiotics, and no food allergy reactions in the past month.

Exclusion Criteria:

  • - Any known cardiovascular disease, cancer, pulmonary disease except well-controlled asthma, or other condition that would preclude an OFC otherwise.
  • - Any medication use that would interfere with an OFC result.
Medications in this category include antihistamines (first or second generation) within 1 week, omalizumab within 3 months, and others listed in the protocol appendix.
  • - Any skin condition aside from well-controlled eczema that might impact TEWL measurement, including such conditions as autoimmune skin conditions (such as psoriasis), congenital ichthyoses, hyper-IgE syndromes.

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.

NCT05696236
Phase

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.

Arms & Interventions

Arms

Experimental: Monitor (TEWL) and stopping rules

Wears the monitor, and the food challenge will be done using the new stopping rules to end the test.

Active Comparator: Monitor (TWLG) without stopping rules

Wears the monitor, but the stopping rules will not be used to end the food challenge. The food challenge will be done following standard oral food challenge procedures.

Interventions

Device: - Transepidermal water loss (TEWL) monitor and stopping rules

The oral food challenge will be done as usual, and participants will wear the TEWL monitor. The research food allergy nurse and doctor will also be looking for signs and symptoms of an allergic reaction. The research study coordinator will be watching the TEWL numbers. If they numbers match the stopping rules, they will tell the doctor and the oral food challenge will be over.

Device: - Monitor (TEWL) without stopping rules
