Akt Inhibitor MK2206 in Treating Patients With Advanced Breast Cancer
Phase II Trial of AKT Inhibitor MK2206 in Patients With Advanced Breast Cancer Who Have Tumors With a PIK3CA Mutation, or an AKT Mutation, and/or PTEN Loss/PTEN Mutation

This phase II trial studies how well Akt inhibitor MK2206 works in treating patients with advanced breast cancer. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES:

I. To determine whether v-akt murine thymoma viral oncogene (Akt) inhibitor MK2206 achieves objective tumor responses (complete response [CR], partial response [PR]) in advanced breast cancer patients who have a phosphoinositide-3-kinase, catalytic, alpha polypeptide (PIK3CA) or Akt mutation and/or phosphatase and tensin homolog (PTEN) loss or mutation.

SECONDARY OBJECTIVES:

I. To determine the 6 month progression-free survival on MK2206. II. To determine baseline molecular markers that may predict clinical outcome. III. To determine pharmacodynamic markers in blood and tumor tissue that may predict a decrease in Ki-67 and clinical outcome.

IV. To determine safety and tolerability of MK2206 in previously treated patients with advanced breast cancer.

V. To determine if decrease in Ki-67 at 2 weeks correlates with anti-tumor effect (CR, PR, or stable disease [SD] > 6 months).

VI. To determine concordance of PIK3CA and PTEN status between primary tumor and distant metastasis.

VII. To determine concordance of PIK3CA status of circulating free deoxyribonucleic acid (DNA) and distant metastasis.

OUTLINE:

Patients receive Akt Inhibitor MK-2206 orally (PO) on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

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

Inclusion Criteria:

  • Patients must have histologically or cytologically confirmed breast cancer, with diagnosed or suspected metastatic, inoperable locally advanced breast cancer, or inoperable locally recurrent breast cancer
  • Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as > 20 mm with conventional techniques or as > 10 mm with spiral computed tomography (CT) scan
  • Patients who have failed to respond to at least one line of systemic therapy are eligible for MK2206 therapy; if the patient has a human epidermal growth factor receptor 2 (HER2) positive tumor, it is expected that they will have received at least one HER2-targeted therapy in the metastatic setting; if the patient has an estrogen receptor positive (ER+) tumor, it is expected that they will have received at least one ER-targeted therapy in the metastatic setting; patients can be enrolled for molecular screening while on another therapy if the patient is interested in MK2206 therapy upon progression
  • Archived primary tumor biopsies or surgical specimens, or biopsies of recurrence or metastasis, will be available for PIK3CA/Akt mutational analysis and PTEN analysis; patients with surgical samples, or core/punch biopsies available, will be eligible for testing for PIK3CA/Akt status as well as PTEN testing; the most recent sample will be preferred (i.e. in patients with metastatic disease, metastases samples are preferred over archival primary tumor and in patients with local recurrences a biopsy of the recurrence is preferred over archival primary tumor); NOTE: PIK3CA or Akt mutation status can be determined on fine needle aspirate (FNA) samples, but PTEN status cannot as stroma and endothelial cells are used as internal controls and PTEN testing has not been validated on FNA samples; thus patients with only FNA samples and no tissue blocks available will be considered to be eligible for screening for PIK3CA/Akt mutations and will be enrolled onto the study only if they are found to have PIK3CA mutations or Akt mutations; patients whose tumors have already been tested in the CLIA environment and have been found to have a PIK3CA mutation or Akt mutation or PTEN loss by immunohistochemistry (IHC) or PTEN mutation will be eligible for treatment; patients whose tumors have been tested in the research environment and found to have a PIK3CA mutation or Akt mutation or PTEN loss or PTEN mutation will have their marker status confirmed in the CLIA environment
  • Patients whose tumors have already been tested in the CLIA environment and have been found to have a PIK3CA mutation or Akt mutation or PTEN loss or mutation will be eligible for treatment; patients whose tumors have been tested in the research environment and found to have a PIK3CA mutation or Akt mutation or PTEN loss or mutation will have their marker status confirmed in the CLIA environment.
