Recruitment details

Nucleos(t)ide analog (NA) treatment completion criteria (alanine aminotransferase [ALT] less than [<]3*upper limit of normal[ULN], HB virus deoxyribonucleic acid [HBV DNA] <lower limit of quantification [LLOQ]:20 International Units per milliliter [IU/mL], HBeAg negative & HB surface antigen [HBsAg] <10 IU/mL).

Screening details

Per protocol amendment (PA) 5 (01 October 2021), all subjects stopped JNJ-56136379 (JNJ-6379) treatment and continued treatment with JNJ-73763989 (JNJ-3989) plus nucleos(t)ide analog (NA; ETV, TD, or TAF) plus optional pegylated interferon alpha-2a (PegIFN-alpha2a). Study consisted of 3 phases: screening phase, OL intervention phase and FU phase.

After PA 5, subjects stopped JNJ-6379 and continued JNJ-3989+NA. With separate consent, subjects received optional treatment: PegIFN-alpha-2a 180 micrograms(mcg) SC injection once weekly(QW) post Week 40 liver biopsy for either 12 or 24 weeks (anytime between study Week 40 to 72) at investigator's discretion. At end of treatment Week 48, all subjects entered FU phase and stopped JNJ-3989/JNJ-6379 and NA (if NA treatment completion criteria was met as per Week 44 laboratory tests). If NA treatment completion criteria were not met at Week 48, NA was continued till FU phase end (study Week 96).

Follow-up Phase: Panel 1

Arm description

After completion of open-label phase (up to 48 weeks) all subjects (with HBeAg positive and not currently treated) enrolled prior to PA 5, entered FU phase & stopped all study drugs including NA treatment, but NA treatment continued till end of FU (study Week 96), if NA treatment completion criteria (ALT: <3*ULN, HBV DNA <LLOQ:20 IU/mL, HBeAg negative and HBsAg<10 IU/mL) was not met at Week 48. Subjects on treatment with optional PegIFN-alpha-2a 180 mcg SC injection QW after Week 40 liver biopsy but had not met NA treatment completion criteria at Week 48, were assessed at end of treatment with PegIFN-α2a (study Week 60 or 72) and stopped NA, if NA treatment completion criteria were met. Subjects who met NA treatment completion criteria (at Week 48) were monitored Q4W in FU phase. If NA-retreatment criteria:HBV DNA >20,000 IU/mL, HBV DNA >2,000 IU/mL but <20,000 IU/mL & ALT>5*ULN was met, NA retreatment was started.

Panel 1 and 2: Absolute Change From Baseline in the Percentage of Hepatitis B Surface Antigen (HBsAg) Hepatocytes at Week 40 ^[1] ^[2]

End point description

Absolute change from baseline to on-treatment liver biopsy timepoint (Week 40) in terms of the percentage of HBsAg-positive hepatocytes (at Week 40) were reported. Intent-to-treat (ITT) population included subjects who were randomly assigned or enrolled to an intervention arm and received at least 1 dose of intervention. Subjects were analyzed according to study intervention they were randomly assigned or enrolled. Here "N" (Number of subjects analysed) signifies the number of subjects that were evaluable for this endpoint. Data for this endpoint was planned to be collected and analyzed for Panels 1 and 2 alone.

Notes
[1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
Justification: No inferential statistics was done. Only descriptive statistics was performed.
[2] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: Data for this endpoint was planned to be collected and analyzed for Panels 1 and 2 alone.

End point description

Virologic flare (VF) per derivation 1 was defined only for subjects who were off-treatment [OFT: period after stopping all study drugs, including NA] and who had HBV DNA<LLOQ (<20 IU/mL) at last observed point on-treatment [OT]); start date [SD] of confirmed VF was first date of 2 consecutive visits with HBV DNA >200 IU/mL. End date [ED] of same confirmed VF was first date when HBV DNA value returns to <=200 IU/mL or date of NA restart, whichever comes first. Each virologic flare were categorized based on confirmed (that is, 2 consecutive values) peak HBV DNA above any of 3 thresholds within the start and end date of that flare as followed: 20,000 IU/mL, 2,000 IU/mL, and 200 IU/mL. Subjects were counted only once for any given flare, regardless of the number of times they actually experienced the flare. ITT set were analysed.

Prior to PA 5, subjects received either JNJ-3989 200 milligrams (mg) subcutaneous(SC) injection every 4 weeks(Q4W) from Day 1 (Week 1) to Week 44+JNJ-6379 250 mg once daily(QD)+NA (ETV 0.5 mg/TD 245 mg/TAF 25 mg) QD from Day 1 (Week 1) to Week 48 or JNJ-3989 200 mg SC injection Q4W from Day 1 (Week 1) to Week 44+NA (ETV 0.5 mg/TD 245 mg/TAF 25 mg) QD from Day 1 (Week 1) to Week 48. After PA 5, subjects stopped JNJ-6379 and continued JNJ-3989+NA. With separate consent, subjects received optional treatment: PegIFN-alpha-2a 180 micrograms(mcg) SC injection once weekly(QW) post Week 40 liver biopsy for either 12 or 24 weeks (anytime between study Week 40 to 72) at investigator's discretion. At end of treatment Week 48, all subjects entered FU phase and stopped JNJ-3989/JNJ-6379 and NA, if NA treatment completion criteria was met as per Week 44 laboratory tests. If NA treatment completion criteria were not met at Week 48, NA was continued till FU phase end (study Week 96).

Were there any global substantial amendments to the protocol? Yes

01 Oct 2021

The primary reasons for this amendment was to remove JNJ-6379 as study intervention, to add a new nucleos(t)ide analog (NA) re-treatment criterion for subjects who discontinued NA treatment during follow-up, and to include more frequent monitoring for subjects who discontinued NA treatment during follow-up.

25 Nov 2021

The primary purpose of this protocol amendmentwas to update the criteria for post-treatment monitoring and for nucleos(t)ide analog (NA) re-treatment for subjects who discontinued NA treatment at Week 48.

Were there any global interruptions to the trial? No

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
