简要总结
The purpose of this study is to explore the potential dose response relationship between the pharmacokinetics of GSK2141795 and [18F] FDG PET pharmacodynamic markers of glucose metabolism in tumor tissue. Three to six subjects will be enrolled in each cohort and dosed with repeat escalating doses of GSK2141795. [18F] FDG PET imaging and optional tumor biopsies will be done prior to initiation of dosing and sequentially at select time points during the first five weeks of dosing. The maximal dose of a given schedule evaluated in this study will not exceed the maximal tolerated dose established in the first-time-in-human trial PCS112689 for the same schedule.
