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). | ||||||||||||||||||||||||

An AE was any untoward medical occurrence in a clinical study subject administered a medicinal (investigational or non-investigational) product.

Panel 1, 2 and 3: Percentage of Subjects With Worst (Grade 3 and 4) Treatment-emergent Division of Acquired Immunodeficiency Syndrome (DAIDS) Toxicity Grade in Clinical Laboratory Tests | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
End point description |
Clinical laboratory test parameters were Hematology : absolute neutrophil count (ANC); Chemistry : alanine aminotransferase (ALT) and serum glutamic pyruvic transaminase (SGPT), aspartate aminotransferase(AST) or serum glutamic oxaloacetic transaminase (SGOT), amylase (pancreatic and total), creatinine Kinase, creatinine, low-density lipoprotein (LDL), lipase, estimated glomerular filtration rate (eGFR) on serum creatinine (Cr). DAIDS toxicity grades (Gd) were Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Potentially Life-Threatening). Percentage of subjects with treatment-emergent DAIDS toxicity Grade 3 or 4 were reported in this endpoint. For toxicity grades, treatment-emergent was concluded if the postbaseline grade was worse than the baseline grade. Only those abnormality with at least one subject were reported. Safety analysis set. Subjects were analyzed as per study intervention they actually received. "n"=number of subjects analyzed at specified categories.

Panel 1, 2 and 3: Percentage of Subjects With Worst (Abnormally Low/High)Treatment-emergent DAIDS Toxicity Grade in Electrocardiogram (ECG) | |||||||||||||||||||||||||||||||||||||||||||||||||
End point description |
ECG parameters included ECG mean heart rate (HR)(beats per minute[bpm]), Pulse rate (PR) interval (milliseconds [ms]), QRS duration (ms) and QTc Corrected (Fridericia’s formula QTcF). Abnormalities were graded as follows: ECG mean heart rate (abnormally low HR <45 bpm) and (abnormally high HR>=120 bpm); PR interval (abnormally high >220 ms) and QPRS (abnormally high >=120 ms); OT interval corrected for heart rate according to Fridericia (QTcF); borderline prolonged (BRD Pr )QTc (>=450 to <=480 ms), prolonged QTc (>=480 to <=500 ms)and pathologically prolonged QTc (>500 ms). For worst abnormality, treatment-emergent was concluded if the abnormality worsened as compared to the abnormality at baseline: abnormally high to abnormally low and vice-versa. Only those abnormality with at least one subject had data were reported. Safety analysis set. Subjects were analyzed as per study intervention they actually received.

Subjects on treatment with optional PegIFNalpha-2a 180 mcg SC injection QW post 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) & 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Reporting group description |
After PA 5, subjects received either JNJ-3989 200 mg SC injection Q4W from Day 1 (Week 1 to Week 44) + JNJ-6379 250 mg QD and NA treatment (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 discontinued JNJ-6379 and continued JNJ-3989 + NA. With separate consent, subjects received optional treatment with PegIFNalpha-2a 180 mcg SC injection QW after 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). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Amendment |
||
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. |
