Overview
This study will examine the safety and tolerability of single and multiple doses of IB-001, and will be conducted in two parts:
Part A: SAD study in approximately 60 Healthy Volunteers (HV). Part B: MAD study in approximately 30 adult participants living with Chronic Hepatitis B (CHB).
Description
This is a first-in-human, double-blind, randomized, placebo-controlled Phase 1 study of IB-001 administered subcutaneously to evaluate safety, tolerability, PK/PD, and preliminary antiviral activity.
The study is comprised of two parts:
Part A: Single Ascending Dose (SAD) in Healthy Volunteers Up to 60 healthy adult participants in up to six cohorts (n=10 per cohort; 8 active:2 placebo). Participants will receive a single sub-cutaneous dose of investigational product followed by a 28-day post treatment follow-up. .
Part B: Multiple Ascending Dose (MAD) in Treatment-Naïve or Currently-Not-Treated Adults with Chronic Hepatitis B (CHB) Up to 30 adult participants (3 cohorts; n=10 per cohort; 8 active:2 placebo). Once-weekly sub-cutaneous dosing over 4 weeks with 6-week post-treatment follow-up. Dose recommendations in both Part A and Part B will be made by the Safety Review Committee (SRC) based on review of emerging safety data.
