Clinical Trial Summary

The purpose of this study is to characterize the safety and tolerability of repeat doses of compound 1278863A in healthy subjects.

Description:

Compound 1278863A 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. Compound 111427 was the first administration of compound 1278863A to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single oral doses up to 300 mg in healthy adult subjects. This study, PHI112842, will be the first administration of compound 1278863A to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of repeat oral doses up to 300 mg for 14 days in healthy adult subjects. At least 6 subjects will complete each cohort. Multiple blood samples for pharmacokinetic analyses will be obtained post-dose in each cohort. Safety will be assessed by measurement of vital signs, cardiac monitoring, collection of adverse event assessments and laboratory safety tests. Blood samples will be collected for pharmacodynamic analyses.

4. The values of the following tests at screening are:

• TIBC: outside the reference range

• Serum iron: outside the reference range

• Serum ferritin: outside the reference range

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

6. Clinically significant abnormal CPK determined by the investigator and GSK Medical Monitor.

7. Calculated creatinine clearance: < 60mL/min

12. Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.

13. 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 drug

14. History of sensitivity to any of the study drugs, 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.

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

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

23. Consumption of red wine, seville oranges, grapefruit or grapefruit juice, exotic citrus fruits, grapefruit hybrids or fruit juices of the prohibited fruits from 7 days prior to the first dose of study medication

24. 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).

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

26. Subject is mentally or legally incapacitated.
