Effects of Inhaled Epinephrine on Systemic Allergic Reactions During Allergy Testing, Immunotherapy or Oral Challenges

A Phase 1b, Open-Label, Exploratory Study Evaluating the Effects of Inhaled Epinephrine in Individuals Experiencing Systemic Allergic Reactions During Allergy Testing, Immunotherapy or Oral Challenges

Sponsor

Dr. George Luciuk

Enrollment

100 participants

Start Date

Aug 25, 2025

Study Type

INTERVENTIONAL

Conditions

Anaphylaxis Hypersensitivity

Summary

The goal of this exploratory study is to evaluate the effects of inhaled epinephrine in subjects, who may not be eligible for the GHL-101 trial, and who are experiencing systemic allergic reaction (SAR) that occur following allergy testing, subcutaneous immunotherapy (SCIT), oral challenges (with food and/or drug) or oral immunotherapy (OIT).

Eligibility

Min Age: 12 Years

Inclusion Criteria3

Males or females, aged ≥ 12 years with known or suspected allergen sensitivity who can also have a clinical history of immunoglobulin E (IgE)-mediated allergy, including a documented sensitivity to allergens (i.e., positive skin prick test, or positive in vitro serum IgE).
Have undergone either a) allergy testing for suspected sensitivity/allergy, b) future oral challenge (food and/or drug) or future OIT to treat existing allergies or c) SCIT AND experienced a SAR Grade 2 or higher, following allergy testing, SCIT, or oral challenges (food and/or drug) for future OIT, and deemed eligible for enrollment by the Principal Investigator.
For females of child-bearing potential, not pregnant or lactating, willing to use an acceptable contraception\* method between Screening and End-of-Study Visits.

Exclusion Criteria7

Known reaction or sensitivity to epinephrine or any of the ingredients of inhaled epinephrine.
Known history or presence of clinically disease/condition that could confound the results of the study or place the subject at undue or additional risk per the judgment of the Investigator.
Abnormal vital signs at screening (i.e., systolic blood pressure: \< 90 or \>140 mmHg, diastolic blood pressure: \< 40 or \> 90 mmHg or, heart rate: \< 45 or \> 100 bpm), respiration rate \< 8 or \> 20 resp./min.
Females who are pregnant, plan to become pregnant or lactating.
Participation in another clinical study involving an investigational drug within 30 days prior to screening, an investigational biologic within 60 days prior to screening, or current/planned participation in another interventional study during this study.
Previous treatment in this study.
Any other reason that, in the opinion of the Investigator, is likely to unfavorably alter subject risk-benefit, confound results, or make it difficult for the subject to fully comply with study requirements.
