Inclusion criteria
. Males or females, aged ≥ 18 years with known or suspected metabisulfite 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) oral challenge (food and/or drug), c) oral immunotherapy (OIT) to treat existing allergies or d) subcutaneous immunotherapy (SCIT) following a prior allergic reaction AND experiences a systemic allergic reaction (SAR) rated as Grade ≥2, following allergy testing, SCIT, oral challenge (food and/or drug), or OIT, and deemed eligible for enrollment by the Principal Investigator.
. For females of child-bearing potential, not pregnant or lactating, willing to use a highly effective method of birth control between Screening and End-of-Study Visits.

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.
. Known reaction or sensitivity to epinephrine or any of the ingredients of inhaled epinephrine.
. Known history or presence of clinically relevant cardiovascular, respiratory, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurological, psychological or other 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.
. Uncontrolled asthma or chronic obstructive pulmonary disease (COPD).
. Recent life-threatening asthma within the last 6 months which required admission to hospital prior to study start.
. Use of any tobacco or of any inhaled products, including vaping and water pipes (Hookahs) within 12 months prior to screening and/or a 10 pack per year history of use.
. Use of antihistamines within 5 days and/or bronchodilators within 24 hours of pre-challenge visit.
. Surgical procedures within 90 days of screening that could result in confounding of results or additional risk to the subject, 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.
