Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Participants who have documented chronic HBV infection greater than equal to (\>=6) months prior to screening and not currently on nucleos(t)ide analogue therapy population defined as participants who never received HBV treatment (treatment naive) or must have ended nucleos(t)ide therapy at least 6 months prior to the screening visit; OR Currently receiving stable nucleos(t)ide analogue therapy population defined as no changes to their nucleos(t)ide regimen from at least 6 months prior to screening and with no planned changes to the stable regimen over the duration of the study.
* Plasma or serum HBsAg concentration \>100 international units per milliliter (IU/mL).
* Plasma or serum HBV DNA concentration: Participants not currently on nucleos(t)ide analogue therapy, plasma or serum HBV DNA \>2000 IU/mL; Participants who are receiving stable nucleos(t)ide analogue therapy must be adequately suppressed, defined as plasma or serum HBV DNA \<90 IU/mL.
* Male and/or Female: A male participant is eligible to participate if they agree to the following during the intervention period and for at least 90 days after the last dose of study treatment: Refrain from donating sperm AND be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent or Must agree to use contraception/barrier as detailed below: Agree to use a male condom (and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak) when having sexual intercourse with a woman of childbearing potential who is not currently pregnant. A female participant is eligible to participate: If she is not pregnant or breastfeeding AND at least one of the following conditions applies: Is not a woman of childbearing potential (WOCBP) OR is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of \<1 percent per year), preferably with low user dependency during the intervention period and for at least 90 days after the last dose of study treatment; A WOCBP must have both a confirmed menstrual period prior to the first dose of study intervention (additional evaluation \[e.g., amenorrhea in athletes, birth control\] should also be considered) and a negative highly sensitive pregnancy test (urine or serum) within 24 hours before the first dose of study treatment.
* Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
* The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
* Capable of giving signed informed consent.
Exclusion Criteria
* Co-infection with Current or past history of Hepatitis C virus (HCV), Human immunodeficiency virus (HIV), Hepatitis D virus (HDV).
* History of or suspected liver cirrhosis and/or evidence of cirrhosis as determined by both Aspartate aminotransferase (AST)-Platelet Index (APRI) \>2 and FibroSure/FibroTest result \>0.7. If only one parameter (APRI or FibroSure/FibroTest) result is positive, a discussion with the Medical Monitor is required before inclusion in study is permitted. Regardless of APRI of Fibrosure/FibroTest score, if the participant meets one of the following criteria, they will be excluded from the study: Liver biopsy (i.e., Metavir Score F4); Liver stiffness \>12 kilopascals (kPa).
* Diagnosed or suspected hepatocellular carcinoma as evidenced by the following: Alpha-fetoprotein concentration \>=200 nanogram per milliliter (ng/mL); If the screening alpha fetoprotein concentration is \>=50 ng/mL and \<200 ng/mL, the absence of liver mass must be documented by imaging within 6 months before randomization.
* History of malignancy within the past 5 years with the exception of specific cancers that are cured by surgical resection (e.g., skin cancer). Participants under evaluation for possible malignancy are not eligible.
* History of vasculitis or presence of symptoms and signs of potential vasculitis (e.g., vasculitic rash, skin ulceration, repeated blood detected in urine without identified cause) or history/presence of other diseases that may be associated with vasculitis condition (e.g., systemic lupus erythematosus, rheumatoid arthritis, relapsing polychondritis, mononeuritis multiplex).
* History of extrahepatic disorders possibly related to HBV immune conditions (e.g., nephrotic syndrome, any type of glomerulonephritis, polyarteritis nodosa, cryoglobulinemia, uncontrolled hypertension).
* Anti-neutrophil cytoplasmic antibodies (ANCA) at screening by itself won't be an exclusion criterion, but if results are borderline positive or positive: myeloperoxidase-ANCA (MPO-ANCA) (Perinuclear antineutrophil cytoplasmic antibodies \[pANCA\]) and proteinase 3- ANCA (PR3-ANCA) (Cytoplasmic antineutrophil cytoplasmic antibodies \[cANCA\]) analysis will be conducted; A discussion with the Medical Monitor will be required to review participant's complete medical history to ensure no past history or current manifestations of a vasculitic/inflammatory/auto-immune condition before inclusion in study is permitted.
* Low complement C3 (C3) at screening by itself won't be an exclusion criterion, but if it is present: A discussion with the Medical Monitor is required to review participant's complete medical history to ensure no past history or current manifestations of vasculitic/inflammatory/auto-immune conditions.
* Currently taking, or took within 3 months of screening, any immunosuppressing drugs (e.g., prednisone), other than a short course of therapy (\<=2 weeks) or topical/inhaled steroid use.
* Participants for whom immunosuppressive treatment is not advised, including therapeutic doses of steroids, will be excluded.
* Currently taking, or took within 12 months of screening, any interferon-containing therapy.
* Participants requiring anti-coagulation therapies (for example warfarin, Factor Xa inhibitors or anti-platelet agents like clopidogrel).
* The participant has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 5 half-lives (if known) or twice the duration (if known) of the biological effect of the study treatment (whichever is longer) or 90 days (if half-life or duration is unknown).
* Prior treatment with any oligonucleotide or small interfering ribonucleic acid (RNA) (Small interfering RNA \[siRNA\]) within 12 months prior to the first dosing day.
* Fridericia's QT correction formula (QTcF) \>=450 milliseconds (msec) (if single electrocardiogram \[ECG\] at screening shows QTcF\>=450 msec, a mean of triplicate measurements should be used to confirm that participant meets exclusion criterion).
* Laboratory results as follows: Serum albumin \<3.5 grams per deciliter (g/dL), Glomerular filtration rate (GFR) \<60 milliliter per minute per 1.73 square meter (mL/min /1.73 m\^2) as calculated by the Chronic Kidney Disease Epidemiologic Collaboration (CKD-EPI) formula (for Japan, Japanese Society of Nephrology Chronic Kidney Disease Initiative \[JSN-CKDI equation\]), International normalized ratio (INR) \>1.25. Platelet count \<140 times 10\^9 cells/L, Total bilirubin \>1.25 times ULN. For participants with benign unconjugated hyperbilirubinemia with total bilirubin \>1.25 times ULN, discussion for inclusion to the study is required with the Medical Monitor, Urine albumin to creatinine ratio (ACR) \>=0.03 mg/mg (or \>=30 mg/g). In the event of an ACR above this threshold, eligibility may be confirmed by a second measurement. In cases where participants have low urine albumin and low urine creatinine levels resulting in a urine ACR calculation \>=0.03 mg/mg (or \>=30 mg/g), the investigator should confirm that the participant does not have a history of diabetes, hypertension or other risk factors that may affect renal function and discuss with the Medical Monitor, or designee.
* History of/sensitivity to GSK3228836 or components thereof or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation.
