Trial overview
Official title: A Sponsor un-blinded, Placebo-controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single and Repeat, Ascending Doses of GSK2798745 in Healthy Subjects and Stable Heart Failure Patients
Trial description: This study is the first administration of GSK2798745 in humans. This will be a sponsor un-blinded, placebo-controlled study to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of GSK2798745, given as single and repeat oral doses to healthy subjects and stable heart failure (HF) subjects. Approximately 28 healthy subjects will be enrolled in the study cohorts (Cohort 1-3) involving single and repeat dose escalations of GSK2798745, while up to 24 stable heart failure subjects will be enrolled in Cohort 4 involving single and repeat dose administration of GSK2798745, with the dose selected based on data from healthy subject cohorts. This would be followed by enrollment of up to 8 subjects with heart failure in Cohort 5 involving repeat dose administration of GSK2798745. The study duration, including screening and follow-up, is not expected to exceed 17 weeks for subjects in the study (in any cohort).

Accepts healthy volunteers
Yes
- For Healthy Subject Cohorts (1-3):
- Male or female 18-75 years of age inclusive, at the time of signing the informed consent.
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- History of acute coronary syndromes (including unstable angina), coronary angioplasty, or stenting within the past 6 months.
Inclusion and exclusion criteria
Inclusion criteria:
- For Healthy Subject Cohorts (1-3):
- Male or female 18-75 years of age inclusive, at the time of signing the informed consent.
- Healthy as determined by a responsible and experienced physician, based on an evaluation including medical history, physical examination, laboratory tests and cardiac evaluation including ECG and echocardiogram. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator in consultation with the GSK Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Body weight >=50 kilogram (kg) and Body Mass Index (BMI) within the range 18-32 kilogram/ square meter (kg/m^2) (inclusive).
- A female subject is eligible to participate if she is of Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy for this definition, “documented” refers to the outcome of the Investigator's/designee’s review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject’s medical records; or postmenopausal defined as 12 months of spontaneous amenorrhea. In questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli-International Units per milliliter (mIU/mL) and estradiol <40 picogram/millilitre (pg/mL) [<147 picomoles/liter (pmol/L)] is confirmatory.
