Akt Inhibitor MK2206 in Treating Patients With Previously Treated Colon or Rectal Cancer That is Metastatic or Cannot Removed by Surgery
This phase II trial studies how well Akt inhibitor MK2206 works in treating patients with previously treated color or rectal cancer that is metastatic or cannot be removed by surgery. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

|Official Title:||A Phase 2 Study of MK-2206 in Previously Treated Metastatic Colorectal Cancer Patients Enriched for PTEN Loss and PIK3CA Mutation|
- Overall response rate (CR+PR) evaluated using RECIST version 1.1 [ Time Frame: Up to 18 months ] [ Designated as safety issue: No ]
- Validation of the enrichment biomarker signature in metastatic sites [ Time Frame: Up to 18 months ] [ Designated as safety issue: No ]Samples will be analyzed using the Wilcoxon rank test. Chi-square or Fisher's exact test where appropriate will be used to determine whether high levels of marker expression correlate with PTEN status.
- PFS [ Time Frame: From start of treatment to time of progression or death, whichever occurs first, assessed up to 18 months ] [ Designated as safety issue: No ]Estimated using the Kaplan and Meier product limit method. Cox proportional hazards regression model will be used to identify prognostic factors for PFS.
- OS [ Time Frame: Up to 18 months ] [ Designated as safety issue: No ]Estimated using the Kaplan and Meier product limit method. Cox proportional hazards regression model will be used to identify prognostic factors for OS.
- DR [ Time Frame: From the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, assessed up to 18 months ] [ Designated as safety issue: No ]Estimated using the Kaplan and Meier product limit method. Cox proportional hazards regression model will be used to identify prognostic factors for DR.

Experimental: Treatment (Akt inhibitor MK2206)
Patients receive Akt inhibitor MK2206 PO on days 1, 8, 15, and 22. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

I. To determine the response rate to MK-2206 (Akt inhibitor MK2206), defined as complete response (CR) + partial response (PR).
I. To determine response rate to MK-2206 in patients with phosphatase and tensin homolog (PTEN) loss or phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) mutation in a pretreatment biopsy from a metastatic site.
II. To determine progression-free survival (PFS) and overall survival (OS). III. To determine the time to treatment failure (TTF), and duration of tumor response (DR).
IV. To determine the safety profile and tolerability of this regimen in this patient population.
V. To determine effect of PTEN, v-raf murine sarcoma viral oncogene homolog B1 (BRAF), PIK3CA, and v-akt murine thymoma viral oncogene homolog 1 (AKT) mutations and semi-quantitative grading of PTEN expression on clinical response.
Patients receive Akt inhibitor MK2206 orally (PO) on days 1, 8, 15, and 22. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6 months.
