55 Years
Gender
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody
result within 3 months of screening

- A positive pre-study drug screen. A minimum list of drugs that will be screened for
include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines

- A hemoglobin value at Screening is of: Healthy male subjects or post-menopausal
females: > 16.5 g/dL, Healthy female (non-childbearing potential) subjects: > 15.5
g/dL

- The values of hematological parameters at screening are: MCV: outside the reference
range and deemed clinically significant by the investigator and GSK Medical Monitor.

- The values of the following tests at Screening, for healthy subjects are: TIBC:
outside the reference range of the population being studied, Serum iron: outside the
reference range of the population being studied, Serum ferritin: outside the reference
range of the population being studied

- A value at screening is greater than the upper limit of reference range for the
following clinical laboratory parameters: AST, ALT, direct bilirubin.

- Clinically significant abnormal CPK determined by the Investigator and GSK Medical
Monitor.

- Calculated creatinine clearance: < 80 mL/min

- A positive test for HIV antibody

- History of drug abuse or dependence within 6 months of the study.

- History of regular alcohol consumption within 6 months of the study

- History or regular use of tobacco- or nicotine-containing products within 6 months
prior to screening.

- Use of prescription or non-prescription drugs, including vitamins, herbal and dietary
supplements (including St John's Wort) within 7 days (or 14 days if the drug is a
potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first
dose of study medication, unless in the opinion of the Investigator and GSK Medical
Monitor the medication will not interfere with the study procedures or compromise
subject safety. By exception, subject may take acetaminophen (<2 grams/day) up to 48
hours prior to the first dose of study drug.

- History of sensitivity to any of the study medications, or components thereof or a
history of drug or other allergy that, in the opinion of the investigator or GSK
Medical Monitor, contraindicates their participation.

- History of sensitivity to heparin or heparin-induced thrombocytopenia (if the clinical
research unit uses heparin to maintain intravenous cannula).

- Subjects with a pre-existing condition interfering with normal gastrointestinal
anatomy or motility, and/or hepatic function that could interfere with the absorption,
metabolism, and/or excretion of the study drugs. Examples of conditions that could
interfere with normal gastrointestinal anatomy or motility include cholecystectomy,
gastrointestinal bypass surgery, partial or total gastrectomy, small bowel resection,
vagotomy, malabsorption, Crohn's disease, ulcerative colitis, or celiac sprue.
Examples of conditions that could interfere with hepatic function include Gilberts
syndrome.

- History of peptic ulcer disease or chronic rectal bleeding.

- History of malignancy. Non-melanoma skin cancer that has been definitely removed is
allowed.

- Subjects with a baseline medical history of proliferative diabetic retinopathy,
preproliferative diabetic retinopathy, or wet age-related macular degeneration (AMD).

- Pregnant females as determined by positive serum or urine hCG test at screening or
prior to dosing.

- Lactating females.

- Where participation in the study would result in donation of blood or blood products
in excess of 500 mL within a 56 day period.

- Unwillingness or inability to follow the procedures, or lifestyle and/or dietary
restrictions outlined in the protocol.

- Consumption of >3 servings per day of red wine, grapefruit (juice), blood orange
(juice), star fruit, onions, kale, broccoli, green beans, or apples from 7 days prior
to the first dose of investigational product, unless in the opinion of the
Investigator and GSK Medical Monitor this will not interfere with the study procedures
and compromise subject safety.

- 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: 30 days, 5 half-lives or twice the duration of the biological effect of the
investigational product (whichever is longer).

- Exposure to more than four new chemical entities within 12 months prior to the first
dosing day.

- Subject is mentally or legally incapacitated.

Summary
Brief summary
GSK1278863A is a novel small molecule agent, which stimulates erythropoiesis through
inhibition of hypoxia-inducible factor (HIF)-prolyl hydroxylases (EGLNs). This compound is
being developed for the treatment of anemia. This study, PHI115385, will be the first
administration of GSK1278863A to Japanese subjects to investigate the safety, tolerability,
pharmacokinetics, and pharmacodynamics of single oral doses in healthy Japanese adult
subjects. Healthy Caucasian adult subjects will be included in order to compare
pharmacokinetics of GSK1278863A and its metabolite(s), and pharmacodynamics of GSK1278863A.
