Treatment: Drugs - tenofovir disoproxil
Treatment: Drugs - antihistamine
Experimental: Cohort 1 - Treatment-naïve, hepatitis B "e" antigen (HBeAg)-positive participants with chronic hepatitis B (CHB) of any genotype administered ARC-520 (2 mg/kg intravenous \[IV\]) every 4 weeks for 48 weeks (13 doses).
Experimental: Cohort 2 - Treatment-naïve, HBeAg-positive, Genotype B participants with CHB administered ARC-520 (2 mg/kg increasing to 4 mg/kg or 4 mg/kg IV) every 4 weeks for 48 weeks (13 doses) concomitantly with daily orally administered ETV or TDF for approximately 60 weeks starting Day 1 and weekly subcutaneously administered peginterferon (PEG IFN) alpha 2a for 48 weeks starting Day 87.
Experimental: Cohort 3 - Treatment-naïve, HBeAg-negative, Genotype B participants with CHB administered ARC-520 (2 mg/kg increasing to 4 mg/kg or 4 mg/kg IV) every 4 weeks for 48 weeks (13 doses) concomitantly with daily orally administered ETV or TDF for approximately 60 weeks starting Day 1 and weekly subcutaneously administered PEG IFN alpha 2a for 48 weeks starting Day 87.

Experimental: Cohort 7 - Treatment-naïve, HBeAg-negative or HBeAg-positive participants with hepatitis delta virus (HDV) administered ARC-520 (2 mg/kg increasing to 4 mg/kg or 4 mg/kg IV) every 4 weeks for 48 weeks (13 doses) and weekly subcutaneously administered PEG IFN alpha 2a for 48 weeks starting Day 15.
Experimental: Cohort 8 - Treatment-naïve, HBeAg-positive participants with CHB of any genotype administered ARC-520 (4 mg/kg IV) every 4 weeks for 48 weeks (13 doses).
Treatment: Drugs: ARC-520
ARC-520 will be administered intravenously concomitantly with 0.9% normal saline using an infusion rate of 0.4 mL/min (24 mL/hour) for study treatment and 200 mL/hr for saline.
Treatment: Drugs: entecavir
0.5 mg once daily; oral
Treatment: Other: pegylated interferon alpha 2a
180 mcg; subcutaneous injection once weekly
Treatment: Drugs: tenofovir disoproxil
300 mg once daily; oral
Treatment: Drugs: antihistamine
All participants will be pre-treated with an oral antihistamine selected by the investigator from the list of approved antihistamines that is available in that country. Acceptable antihistamines are: diphenhydramine 50 mg p.o., chlorpheniramine 8 mg p.o., hydroxyzine 50 mg p.o., or cetirizine 10 mg p.o.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs Considered Possibly or Probably Related to Treatment
Query!
Assessment method [1]
0
0
The Principal Investigator (or medically qualified designee) will use clinical judgment to determine the relationship. An adverse event (AE) was considered "possibly related" when there is a reasonable possibility that the incident, experience, or outcome may have been caused by the product under investigation. An AE was considered "probably related" when there are facts, evidence, or arguments to suggest that the event is related to the product under investigation. Only AEs that occurred post-dose were considered treatment-emergent. Clinically significant abnormal laboratory findings or other abnormal assessments that are detected during the study or are present at baseline and significantly worsen following the start of the study will be reported as AEs.
