Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of GSK2126458 and GSK1120212 Combination Therapy in Subjects With Advanced Solid Tumors.

Stopped early · Phase 1

Conditions studied: Cancer

In brief

This is a Phase I, open-label, dose-escalation study to characterize the safety, tolerability, pharmacokinetic profile, pharmacodynamic profile, and clinical activity of the oral PI3K inhibitor GSK2126458 and the oral MEK inhibitor GSK1120212 dosed in combination in subjects with advanced solid tumors. The study will be conducted in 2 parts, a dose escalation phase and a tumor specific cohort expansion.
