Clinical Trial Summary

This is a phase 1, randomised, double blind placebo controlled 2-part study to assess the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of inhaled DMC-IH1 (epinephrine) and relative bioavailability and carryover effects of Inhaled (DMC-IH1) and Intramuscular(IM) (EpiPen®) Epinephrine in healthy male and female participants.


Description:

DMC-IH1 (Investigational product) inhaler is a proprietary single-use capsule based dry powder inhaler designed for oral pulmonary drug delivery in emergency scenarios. This study is in two parts- Part 1 will enrol 24 participants into 3 cohorts receiving a single ascending dose; Part 2 will enrol 39 participants into 3 arms to receive either DMC-IH1 through the inhaler device or epinephrine IM. Each participant will receive 3 doses of epinephrine either inhaled (DMC-IH1) or IM at differing intervals to assess carryover effect. Both Parts 1 and 2 of the study will comprise 3 periods: Screening, Treatment Period and Follow-up .

Participant has presence of any physical or psychological medical condition that, in the opinion of the Investigator, would make it unlikely that the participant will comply with the protocol or complete the study per protocol. 13. Participant has received any of the following vaccinations: 1. Live vaccine(s) within 1 month prior to Screening or plans to receive such vaccines during the study. 2. Killed vaccine 1 week prior to randomization (Day -1/Visit 2). 3. COVID-19 vaccine Day -7 through Visit 3 for Part 1 and through Visit 6 for Part 2 (EOS). 14.
