The purpose of this study is to determine the safety and maximum tolerated dose (MTD) of MK-2206 in combination with paclitaxel and trastuzumab when given to patients with HER2-overexpressing solid tumor malignancies. MK-2206 is an oral drug (taken by mouth) that turns off a protein called AKT inside cancer cells. This could be helpful in treating treatment-resistant cancers, because AKT allows cells to survive despite active anticancer treatment. In the case of HER2-positive cancers, laboratory studies suggest that the drug combination of MK-2206 and paclitaxel and trastuzumab may be effective.
The purpose of this study is to test the safety and safest highest dose of an investigational drug called MK-2206 when given in combination with paclitaxel and trastuzumab in patients with Human Epidermal growth factor Receptor 2 (HER2)-overexpressing solid tumor malignancies.
