Official title: A Double-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Ascending Dose and Multiple Doses of GSK3389404 in Chronic Hepatitis B Subjects
Trial description: GSK3389404 is being developed for the treatment of CHB virus infection. The development goal for GSK3389404 is the establishment of a finite duration treatment that results in sustained suppression of hepatitis B virus (HBV) replication and viral antigen production after cessation of all treatments for CHB due to the restoration of a functional immune response in the absence of high antigen levels. This study is a multicenter, randomized double-Blind (sponsor un-blinded in Part 1), Placebo-controlled Study which will evaluate the safety, tolerability, PK, and PD profile of GSK3389404 in subjects with CHB and aim to establish proof-of-mechanism. The study will be conducted in two parts. Part 1 plans to enroll subjects primarily from the Asia-pacific region, including Japan and will be conducted as a single ascending dose (SAD) study with 5 planned cohorts ranging from 30 milligram (mg) to a maximum of 240 mg GSK3389404. Within each cohort, subjects will be randomized to receive either GSK3389404 or placebo in a 3:1 ratio. Cohorts A, B, C, C1, and D will be conducted in a sequential fashion; Cohort C1 is an optional cohort and may be dosed after Cohort C or in parallel with Cohort D. Part 2 will be conducted as a multiple-dose, dose-ranging study. Subjects will be randomized to different parallel dose levels and regimens or placebo. The dose levels of Part 2 will be selected after a review of Part 1 safety, Pharmacokinetic (PK) and Pharmacodynamic (PD) data. The treatments selected are 60 mg GSK3389404 weekly, 120 mg GSK3389404 bi-weekly, 120 mg GSK3389404 weekly or placebo. An optional Japanese part-2 sub-study is planned. The total study duration for part 1 including screening, treatment, and post-treatment follow-up, will not be expected to exceed 13 weeks for each subject and for part 2, including screening, treatment and post-treatment follow-up, will not be expected to exceed 65 weeks for each subject.

- History of/sensitivity to GSK3389404 or components thereof or a history of drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates their participation.
- Confirmed or suspected hepatocellular carcinoma (HCC) as evidenced by: Alpha-fetoprotein concentration >=200 nanogram (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.
- Liver cirrhosis or evidence of cirrhosis as determined by any of the following: Positive liver biopsy (i.e., Metavir Score F4) within 12 months of screening. Fibroscan >12 kilopascals (kPa) within 12 months of screening. AST-Platelet Index (APRI) >2 and FibroSure result >0.7 within 12 months of screening and Investigator judgment. For subjects without a test for cirrhosis in the above timeframes, APRI and FibroSure should be performed during the screening period to rule out cirrhosis.
- Hepatitis C Virus (HCV) co-infection.
- Human Immunodeficiency Virus (HIV) co-infection.
- Hepatitis D Virus (HDV) co-infection.
- Laboratory results as follows: Total bilirubin concentration >1.25 X ULN. Serum albumin concentration <3.5 grams (g)/deciliter (dL). International normalized ratio (INR) >1.25. Platelet count <140 X 10^9/L. Serum creatinine concentration greater than the ULN. Glomerular Filtration Rate (GFR) <90 mL/min as calculated by the Chronic Kidney Disease Epidemiologic Collaboration (CKD-EPI) formula. Subjects with GFR <90 mL/min but >= 60 mL/min may be considered after consultation with the GlaxoSmithKline 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 subjects 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 subject does not have a history of diabetes, hypertension or other risk factors that may affect renal function and discuss with the PPD or GSK medical monitor, or designee.
- Positive test for blood in urine. In the event of a positive test, the test may be repeated once, and if repeat is negative or if urine microscopy reveals <5 RBC per High-Power Field (HPF), the subject is considered eligible.
- Fridericia’s QT correction formula (QTcF) >=450 milliseconds (msec) (single ECG at screening shows QTcF >=450 msec, a mean of triplicate measurements should be used to confirm that subject meets exclusion criterion).
- 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.
- Current alcohol use as judged by investigator to potentially interfere with participant compliance.
- A positive pre-study treatment screen and an unwillingness to refrain from use of illicit drugs (or substances with abuse potential) and adhere to other protocol-stated restrictions while participating in the study [The screen refers to illicit drugs and substances with abuse potential. Medications that are used by the subject as directed, whether over-the-counter or through prescription, are acceptable and would not meet the exclusion criteria]. .
- Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
- The subject 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 non-GSK oligonucleotide or small interfering ribonucleic acid (RNA) (siRNA) within 12 months prior to the first dosing day or prior treatment with GSK oligonucleotide within 3 months prior to the first dosing day.
- Pregnant or lactating females at screening and prior to dosing.
- For Part 1, females of reproductive potential.
