An Efficacy and Safety Study of a Combination of JNJ-73763989, Nucleos(t)Ide Analogs (NA), and a Programmed Cell Death Protein Receptor-1 (PD-1) Inhibitor in Chronic Hepatitis B Participants

Phase 2
Completed
Conditions
Hepatitis B, Chronic
Interventions
Registration Number
NCT05275023
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

The purpose of this study is to evaluate efficacy of the study intervention, based on hepatitis B surface antigen (HBsAg) levels at follow-up (FU) Week 24.

Detailed Description

JNJ-73763989 (JNJ-3989) is a small interfering ribonucleic acid (siRNA) targeting all hepatitis B virus (HBV) messenger ribonucleic acid (mRNAs). The programmed cell death protein receptor-1 (PD-1) inhibitor aims at preventing the interaction of PD-1 with its ligands. The purpose of this study to determine whether at least one of the combination regimens of JNJ-3989 + PD-1 inhibitor + Nucleos(t)ide analog (NA) is more efficacious than JNJ-3989 + NA treatment. This study will be conducted in 3 periods: screening period, treatment period and follow-up (FU) period. Safety assessments will include adverse events (AEs), serious AEs, clinical safety laboratory tests, electrocardiograms (ECGs), vital signs, and physical examinations. Total duration of individual participation will be up to 78 weeks (including screening period).

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/ biological agent under study. Severity of immune related AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.

Number of Participants with Adverse Events (AEs) by SeverityUp to Week 72

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Severity of adverse event will be graded by using Division of AIDS (DAIDS) grading scale ranges from Grade 1 to Grade 5. Grade 1 indicates a mild event, Grade 2 indicates a moderate event, Grade 3 indicates a severe event, Grade 4 indicates a potentially life-threatening event, Grade 5 indicates death.
