Design outcomes

Primary

MeasureTime frame
1.To evaluate the safety, tolerability and dose-limiting toxicities associated with daily oral doses of ZSTK474 with advanced solid malignancies; 2.To determine the maximal tolerated dose (MTD) and/or recommended dose of ZSTK474 for Phase 2 studies.

Secondary

MeasureTime frame
1.To evaluate the pharmacokinetic (PK) profile of ZSTK474 2.Efficacy 3.To investigate several biomarkers related to the sensitivity to the PI3K inhibitor
