MK2206 and Paclitaxel in Treating Patients With Locally Advanced or Metastatic Solid Tumors or Metastatic Breast Cancer

Stage IV Breast Cancer Clinical Trial

Official title: Phase Ib Dose Escalation and Biomarker Study of MK-2206 in Combination With Standard Doses of Weekly Paclitaxel in Patients With Locally Advanced or Metastatic Solid Tumors With an Expansion in Advanced Breast Cancer

Status Completed

Clinical Trial Summary

This phase I trial studies the side effects and best dose of Akt inhibitor MK2206 (MK2206) when given together with paclitaxel and to see how well they work in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment or breast cancer that has spread to other places in the body. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving Akt inhibitor MK2206 and paclitaxel may be a better treatment for solid tumors or breast cancer.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of the combination of MK-2206 and weekly paclitaxel. (Dose-escalation phase) II. To determine the safety and anti-tumor activity of the combination in metastatic breast cancer. (Expansion phase)

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetics of MK-2206 and weekly paclitaxel used in combination.

II. To determine the safety of MK-2206 and weekly paclitaxel used in combination.

III. To evaluate the toxicities and tolerability of the combination. IV. To document anti-tumor activity. V. To determine baseline molecular markers that may predict clinical activity. VI. To determine pharmacodynamic markers in blood and tumor tissue that may predict an increase in apoptosis (by cleaved caspase 3) and clinical activity.

VII. To determine concordance of phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) and phosphatase and tensin homolog (PTEN) status between primary tumor and distant metastasis.

VIII. To determine concordance of PIK3CA status of circulating tumor cells and distant metastasis.

OUTLINE: This is a dose-escalation study of Akt inhibitor MK2206.

Patients receive paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15 and Akt inhibitor MK2206 orally (PO) once daily (QD) on days 2, 9, and 16. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 3 weeks. ;
