Up to four cohorts will be included in Phase I, with healthy patients to be randomised at a 3:1 ratio to receive a single intranasal INI-2004 dose or placebo.

Inimmune chief marketing officer Jon Ruckle said: “Australia is the ideal location for us to conduct a cost-effective, high-quality Phase I study.

“We already have in place an Australian subsidiary, an experienced Phase I clinical site, and a relationship with a well-respected local contract research organisation.”
