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

Recruiting now · Phase 1

Conditions studied: Hypersensitivity, Anaphylaxis

In brief

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).

Who can join

Age: 12 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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.

You may not qualify if…

• 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.
