About this study
Official title: A Phase 1, Randomized, Double-Blinded, Placebo-Controlled Study to Evaluate Safety, Tolerability, Pharmacokinetics, And Preliminary Efficacy of Single and Multiple Ascending Doses of IB-001 in Healthy Participants and Participants With Chronic Hepatitis B
This study will examine the safety and tolerability of single and multiple doses of IB-001 in two parts:
Part A: SAD study in approximately 50 Healthy Volunteers (HV). Part B: MAD study in approximately 30 adult participants living with Chronic Hepatitis B (CHB).
A separate exploratory, open-label, single-dose cohort (Part C) will evaluate pegylated interferon alfa-2a in HVs for translational benchmarking against IB-001.
Read the detailed 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 three parts:
Part A: Single-dose, multicohort, dose-finding study in approximately 50 adult Healthy Volunteers (HV) in up to five 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: Multidose, multicohort study in Treatment-Naïve or Currently-Not-Treated Adults with Chronic Hepatitis B (CHB).
Approximately 30 adult participants (up to 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.
Part C: Single-dose, open label, single cohort study in approximately 8 adult Healthy Volunteers (HV). Participants will receive a single sub-cutaneous dose of peginterferon alfa-2a followed by a 14 day post treatment follow-up.

What is being measured
The primary outcome is the main question the study is designed to answer.
Part A and Part B: Incidence and Severity of Treatment-Emergent Adverse Events (TEAEs).
Treatment-Emergent Adverse Events (TEAEs) are adverse events that first appear or worsen in severity during the course of the clinical study, regardless of whether they are related to the investigational product (IP) or not. TEAEs will be coded using MedDRA and summarized by SOC, PT, severity, and relationship to IP. Treatment-related AEs (possibly/probably/definitely related) will also be summarized separately. A by-participant AE listing will be provided
Measured: Through Day 29 (Part A), through Day 64 (Part B).
Part A and Part B: Number of Participants with Adverse Events (AEs) by Severity
An AE is any unfavorable medical occurrence in a study participant administered an investigational product. The AE does not necessarily have a causal relationship with the treatment. All AEs will be graded for severity according to NCI-CTCAE classification. If an appropriate AE term is not found in NCI-CTCAE, the AE will be graded as follows: Grade 1 (mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (Severe) and Grade 5 (Death).
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: Number of Participants with Adverse Events (AEs) of Special Interest (AESIs)
AEs of special interest include Cytokine Release Syndrome (CRS), Injection Site Reactions (ISRs) and Unexplained Liver Biochemistry Elevations. Reported AESIs will be graded according to NCI-CTCAE classification. If an appropriate AE term is not found in NCI-CTCAE, the AESI will be graded as follows: Grade 1 (mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (Severe) and Grade 5 (Death).
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: Number of Participants with Clinically Significant Changes in Laboratory Parameters
Assessment Method - Number of participants with clinical laboratory abnormalities (serum chemistry, hematology, and coagulation) will be reported.
Measured: Through Day 15 (Part A), through Day 64 (Part B)
Part A and Part B: Number of Participants with Clinically Significant Changes in Vital Signs.
Number of participants with vital signs abnormalities will be reported. Vital signs include body temperature, pulse rate, respiratory rate, and blood pressure.
Measured: Through Day 15 (Part A), through Day 64 (Part B)
Part A and Part B: Number of Patients with Clinically Significant Changes in Cardiac Parameters.
Number of participants with electrocardiogram (ECG) abnormalities will be reported.
Measured: Through Day 15 (Part A), through Day 64 (Part B)
Secondary outcomes (8)
Part A and Part B: Number of Patients with Clinically Significant Anti-Drug Antibodies (ADAs).
All immunogenicity data (ADA) are to be analyzed using the Immunogenicity Analysis Population. ADA incidence and titer levels over time will be summarized by dose.
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part B: Changes from Baseline in HBsAg levels over time.
Blood samples will be analyzed for HBsAg levels to establish baseline and determine eligibility; subsequent blood samples will be collected at protocol-specified timepoints to measure HBsAg changes over time.
Measured: Through Day 64 (Part B)
Part B: Change from Baseline in Anti-HBs Antibody Titers over time.
Blood samples will be collected at baseline and at protocol-specified timepoints to measure anti-HBs antibody titer changes over time.
Measured: Through Day 64
Part B: Reduction from Baseline in HBV DNA levels over time.
Blood samples will be collected at baseline and at protocol-specified timepoints to measure HBV DNA changes over time.
Measured: Through Day 64
Part A and Part B: PK Parameter - Maximum Observed Serum Concentration (Cmax) of IB-001
The Cmax is the maximum observed concentration of IB-001 in serum following single or multiple ascending dose administration. Blood samples will be collected at baseline and at protocol-specified timepoints.
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Area under the Serum Concentration Time Curve (AUC) of IB-001.
AUC is the area under the concentration time curve of IB-001 in serum following single or multiple ascending dose administration. Blood samples will be collected at baseline and at protocol-specified timepoints.
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Time to Observed Maximum Serum Concentration (Tmax) of IB-001.
Tmax is the time it takes to reach maximum concentration of IB-001 in serum following single or multiple ascending dose administration. Blood samples will be collected at baseline and at protocol-specified timepoints.
Measured: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Terminal Half Life (T1/2) of IB-001.
T1/2 will be measured following single and multiple doses of IB-001. Blood samples will be collected at baseline and at protocol-specified timepoints.
Measured: Through Day 29 (Part A), through Day 64 (Part B)

TEAEs will be coded using MedDRA and summarized by SOC, PT, severity, and relationship to IP. Treatment-related AEs (possibly/probably/definitely related) will also be summarized separately. A by-participant AE listing will be provided
Part A and Part B: Number of Participants with Adverse Events (AEs) by Severity
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
An AE is any unfavorable medical occurrence in a study participant administered an investigational product. The AE does not necessarily have a causal relationship with the treatment. All AEs will be graded for severity according to NCI-CTCAE classification. If an appropriate AE term is not found in NCI-CTCAE, the AE will be graded as follows: Grade 1 (mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (Severe) and Grade 5 (Death).
Part A and Part B: Number of Participants with Adverse Events (AEs) of Special Interest (AESIs)
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
AEs of special interest include Cytokine Release Syndrome (CRS), Injection Site Reactions (ISRs) and Unexplained Liver Biochemistry Elevations. Reported AESIs will be graded according to NCI-CTCAE classification. If an appropriate AE term is not found in NCI-CTCAE, the AESI will be graded as follows: Grade 1 (mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (Severe) and Grade 5 (Death).
Part A and Part B: Number of Participants with Clinically Significant Changes in Laboratory Parameters
Time frame: Through Day 15 (Part A), through Day 64 (Part B)
Assessment Method - Number of participants with clinical laboratory abnormalities (serum chemistry, hematology, and coagulation) will be reported.
Part A and Part B: Number of Participants with Clinically Significant Changes in Vital Signs.
Time frame: Through Day 15 (Part A), through Day 64 (Part B)
Number of participants with vital signs abnormalities will be reported. Vital signs include body temperature, pulse rate, respiratory rate, and blood pressure.
Part A and Part B: Number of Patients with Clinically Significant Changes in Cardiac Parameters.
Time frame: Through Day 15 (Part A), through Day 64 (Part B)
Number of participants with electrocardiogram (ECG) abnormalities will be reported.
8 secondary outcomes
Part A and Part B: Number of Patients with Clinically Significant Anti-Drug Antibodies (ADAs).
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
Part B: Changes from Baseline in HBsAg levels over time.
Time frame: Through Day 64 (Part B)
Part B: Change from Baseline in Anti-HBs Antibody Titers over time.
Time frame: Through Day 64
Part B: Reduction from Baseline in HBV DNA levels over time.
Time frame: Through Day 64
Part A and Part B: PK Parameter - Maximum Observed Serum Concentration (Cmax) of IB-001
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Area under the Serum Concentration Time Curve (AUC) of IB-001.
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Time to Observed Maximum Serum Concentration (Tmax) of IB-001.
Time frame: Through Day 29 (Part A), through Day 64 (Part B)
Part A and Part B: PK Parameter - Terminal Half Life (T1/2) of IB-001.
Time frame: Through Day 29 (Part A), through Day 64 (Part B)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing IB-001 and Peginterferon Alfa-2A in people with Chronic Hepatitis B Virus Infection, run by IntegerBio at 5 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 54 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Hong Kong, Moldova, New Zealand, Ukraine. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
