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.

  • Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods.
  • Body weight > 50 kg and BMI within the range 18.5 - 29.0 kg/m2 (inclusive).
  • Capable of giving written informed consent.
  • QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block.
  • Japanese defined being born in Japan, having four ethnic Japanese grandparents, holding a Japanese passport or identity papers and being able to speak Japanese. Japanese subjects should be also have lived outside Japan for less than 10 years.
  • Caucasian, defined as an individual having four grandparents who are all descendents of the original peoples of Europe.

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.
