Investigate Safety, Pharmacokinetics and Pharmacodynamics of GSK2118436 & GSK1120212

Summary

This was an open-label, dose escalation study to investigate the safety, pharmacokinetics, pharmacodynamics and clinical activity of GSK2118436 and GSK1120212 in combination. This study was designed in four parts. In Part A, the effect of repeat doses of GSK1120212 on the pharmacokinetics of single dose GSK2118436 was investigated prior to evaluating combination regimens. In Part B, the range of tolerated dose combinations was identified using a dose-escalation procedure. In Part C, different dose combinations of GSK2118436 and GSK1120212 were evaluated, based on results from the dose escalation cohorts. In Part D, the pharmacokinetics and safety of GSK2118436 administered as HPMC capsules alone and in combination with GSK1120212 was evaluated.
