Study details:

This is a Phase I/Ib, randomised, double-blind, placebo-controlled study of INI-2004, administered as single or multiple doses. Phase I (SAD) - Healthy Participants will be enrolled and randomised to 4 dose cohorts (n=8 per cohort) to receive single ascending doses of INI-2004 or placebo (ratio 3:1 active: placebo). Dosing in each cohort will commence with two sentinels, with one of the two sentinels randomised to receive INI-2004 and the other randomised to receive placebo.

The safety and tolerability of each sentinel participant will be monitored in the clinic until Day 2 and will be reviewed by the Principal Investigator (PI) prior to dosing the remainder of participants in each cohort. The decision to escalate between cohorts will be made by a safety review committee (SRC) following completion of the Day 3 visit for at least 6 out of 8 participants in the cohort. Cohorts will be dosed in an escalating order.

Phase Ib (MAD) - Phase Ib (MAD) may commence following completion of SAD Cohort 3 or SAD Cohort 4. Up to 3 dose levels are planned to be evaluated. To be eligible for study inclusion, participants must have a positive response to the ragweed nasal allergen challenge at screening.

Cohorts will be dosed in escalating order, with participants in each cohort (up to n=12 per cohort) randomised in blocks of 4 subjects to receive INI-2004 or placebo at a ratio of 3:1 (active:placebo). INI-2004 or placebo will be administered QW, commencing 2 weeks after administration of the second ragweed nasal allergen challenge.
