Study Summary

This is a randomized, partially blind, placebo controlled, clinical trial evaluating a single intranasal dose of BPZE1 in healthy adults. The study will evaluate a lyophilized formulation of the product, with the goal of testing for the optimal dose for subsequent clinical trials. Fifty healthy adults, 18-49 years of age will be randomized to one of the four following treatment groups in a 3:3:3:1 ratio: 10\^7 colony forming units (CFU) of BPZE1 administered by VaxINator device, 10\^9 CFU of BPZE1 administered by VaxINator device, placebo administered by VaxINator device, 10\^9 CFU of BPZE1 administered by needleless tuberculin syringe. Study duration will be approximately 12 months with a subject participation duration of approximately 6 months. The primary objective of this study is to assess the safety and tolerability of a single intranasal dose of either 10\^7 or 10\^9 CFU of lyophilized BPZE1 vaccine.

Primary Outcome

AESIs included medically attended wheezing events given the route of study product administration and the nature of the study product.
