About
This study will assess the safety, tolerability, and the maximum tolerated dose (MTD) of MK-2206 in combination with both trastuzumab and trastuzumab/lapatinib in participants with human epidermal growth factor receptor 2 positive (HER2+) breast cancer and other solid tumors. The primary hypothesis of this study is that the combination of oral MK-2206 with trastuzumab or with trastuzumab/lapatinib will be well tolerated in participants with advanced HER2+ solid tumors.
Full description
This study was divided into 2 parts. In Part 1, cohorts of 3 participants were to be enrolled sequentially on escalating doses of MK-2206 in combination with a fixed dose of trastuzumab. Barring dose-limiting toxicities (DLTs), additional participants were to be enrolled and dose-finding would proceed until an MTD was identified for MK-2206 when dosed either every other day (QOD) or once weekly (QW) in combination with trastuzumab. In Part 2, cohorts of 3 participants were to be enrolled sequentially on rising doses of lapatinib administered in combination with the MTD dose of MK-2206/trastuzumab established in Part 1. Barring DLTs, dose finding would proceed until an MTD of the 3-drug combination was identified.

- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
- Has a primary CNS tumor.
- Has known hypersensitivity to the components of study drugs or its analogs.
- Has a history or evidence of heart disease.
- Has uncontrolled hypertension or diabetes.
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
