Plain-language 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).

Inclusion criteria
. 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 criteria
. Known reaction or sensitivity to epinephrine or any of the ingredients of inhaled epinephrine.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Time to resolution of systemic symptoms
Timeframe: From first dose administration to 60 minutes following first dose administration
2
Time to complete resolution of systemic symptoms
Timeframe: From first dose administration to 60 minutes following first dose administration
. 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.
