Clinical Trial 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.

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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants who Achieve Hepatitis B Surface Antigen (HBsAg) Seroclearance		Follow up Week 24
Secondary	Percentage of Participants who Experience Adverse Events (AEs) of Interest	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. AEs of interest are significant AEs that are judged to be of special interest because of clinical importance, known class effects or based on nonclinical signals.	Up to Week 72
Secondary	Number of Participants with Adverse Events (AEs) by Severity	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.	Up to Week 72
Secondary	Number of Participants with Immune Related Adverse Events (AEs) by Severity	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.	Up to Week 72
Secondary	Number of Participants with Abnormalities in Vital Signs, Physical Examinations, Clinical Laboratory Tests, 12-lead Electrocardiograms (ECGs)	Number of participants with abnormalities in vital sign measurements (including pulse rate and blood pressure, both systolic and diastolic); physical examinations (including height at screening, body weight, skin examination, general appearance, eyes, ears, nose, throat, cardiovascular system, respiratory system, gastro-intestinal system and mucous; clinical laboratory tests (including hematology, clinical chemistry and urinalysis); 12-lead ECGs (heart rate, PR, QRS, QT) will be reported.
