Study to Evaluate the Effect of Bepirovirsen on Cardiac Conduction as Assessed by 12-lead Electrocardiogram in Healthy Volunteers
- Registration Number
- NCT06422767
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
This study will evaluate the effect of a single dose of bepirovirsen on the QT interval corrected by Fridericia's formula (QTcF) as compared to placebo. The data generated will be used to model the relationship between bepirovirsen concentration and QTcF.

Exclusion Criteria
- History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematologic, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention or interfering with the interpretation of data.
- History of vasculitis or presence of symptoms and signs of potential vasculitis
- History of lymphoma, leukemia, or any malignancy except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for at least 3 years.
- Participants with any other medical conditions which, in the judgement of the investigator and/or Medical Monitor, could jeopardize the integrity of the data derived from that participant or the safety of the participant.
- Past, current or intended use of over-the-counter or prescription medication, including herbal medications within 7 days or 5 half-lives (whichever is longer) before dosing.
- Current or recent use of creatine-containing supplements, or intended use up to 50 days post-dosing.
- Prior treatment with any oligonucleotide or small interfering Ribonucleic acid (RNA) (siRNA) within 12 months before dosing.
- Exposure to more than 4 new chemical entities within 12 months before the first dosing day
- Current enrollment or past participation in another investigational study in which an investigational intervention (e.g., drug, vaccine, invasive device) was administered within 5 half-lives (if known) or twice the duration of biological effect (if known), whichever is longer, or within the last 90 days (if half-life and duration of biological effect are unknown), before signing of consent in any other clinical study involving an investigational study intervention or any other type of medical research.
- Current enrollment or past participation in this clinical study.
- Positive pre-clinical drug/alcohol screen, including tetrahydrocannabinol.
- Positive Human Immunodeficiency Virus antibody test.
- History or regular use of tobacco or nicotine-containing products within 6 months prior to screening.
- Regular alcohol consumption within 6 months prior to screening defined as an average weekly intake of >14 units for males or females.
- Regular use of known drugs of abuse, including tetrahydrocannabinol.
- Sensitivity to heparin or history of heparin-induced thrombocytopenia.
- History of sensitivity to bepirovirsen or components thereof or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor contraindicates their participation.
- Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- Positive test results for Hepatitis B surface antigen (HBsAg), hepatitis C antibody or hepatitis C RNA at screening or within 3 months prior to first dose of study intervention.
- Known history of heart disease, including ischemic heart disease, cardiomyopathy, clinically significant cardiac arrhythmias, clinically significant valvular disease, or hypertensive heart disease.
