A Phase 1 interventional study of Inhaled Epinephrine in Hypersensitivity and Anaphylaxis, sponsored by Dr. George Luciuk. Recruiting at 1 site in Canada. Open to participants aged 12 Years and older. Per ClinicalTrials.gov, last updated 2026-08-10.
Sponsored by Dr. George Luciuk · Phase 1, Interventional, and Treatment
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).
This is a Phase 1b, multi-center, open label exploratory study evaluating the effects of inhaled epinephrine in patients who are undergoing planned allergy testing, SCIT, oral challenges (with food and/or drug), or OIT and are not eligible for the GHL-101 study. This study will enroll and dose up to 100 patients.
The maximum duration of subject participation is approximately 1 week.
100 studies on the registry are indexed under Anaphylaxis; 20 are open to participants now.
This study's planned enrollment of 100 is above the median of 40 across 50 interventional studies indexed under Anaphylaxis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

The first inhalation will be administered as soon as possible (i.e., within approximately 30 seconds) following identification of a SAR Grade 2 or higher and confirmation of enrollment by the Principal Investigator. The second inhalation will be administered approximately 10 seconds later, and the subject will be observed for approximately 2 minutes for signs of symptom resolution. Inhalations will continue in this manner until either: 1. resolution of systemic symptoms (defined as a reduction in SAR Grade to ≤1), or 2. if maximum number of inhalations (8 inhalations) has not been reached, complete resolution of systemic symptoms (defined as reduction in SAR Grade to 0) without exceeding maximum 8 inhalations, or 3. administration of intra-muscular epinephrine, whichever occurs earlier. If a recurrence of symptoms is observed, administration may continue until a maximum of 8 inhalations is reached.
Drug: Inhaled Epinephrine
0.125 mg per inhalation. The maximum proposed dose to be administered is 1.0 mg (consisting of 8 inhalations of 0.125 mg over 6 minutes).
Time to resolution of systemic symptoms
Defined as a reduction in systemic allergic reaction (SAR) Grade to ≤ 1. Grade 0 is considered the absence of any symptoms and per World Allergy Organisation's Grading System for Systemic Allergic Reactions, Grade 1 is least severe and Grade 5 is most severe.
Time frame: From first dose administration to 60 minutes following first dose administration
Time to complete resolution of systemic symptoms
Defined as a reduction in systemic allergic reaction (SAR) Grade to 0. Grade 0 is considered the absence of any symptoms and per World Allergy Organisation's Grading System for Systemic Allergic Reactions, Grade 1 is least severe and Grade 5 is most severe.
Time frame: From first dose administration to 60 minutes following first dose administration
Plan to share: Yes — All individual participant data collected during the trial, after deidentification.
