About
This phase II trial studies how well v-akt murine thymoma viral oncogene homolog 1 (Akt) inhibitor MK2206 works in treating patients with previously treated colon or rectal cancer that has spread from the primary site to other places in the body or nearby tissue or lymph nodes and 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.
Full description
PRIMARY OBJECTIVES:
I. To determine the response rate to MK-2206 (Akt inhibitor MK2206), defined as complete response (CR) + partial response (PR).
SECONDARY OBJECTIVES:
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 AKT mutations and semi-quantitative grading of PTEN expression on clinical response.
OUTLINE:
Patients receive Akt inhibitor MK2206 orally (PO) on days 1, 8, 15, and 22. Treatment repeats 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.

Inclusion criteria
Exclusion criteria
Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study; if the patient has residual toxicity from prior treatment, toxicity must be =< grade 1 (or =< grade 2 for peripheral neuropathy and/or alopecia)
Patients who are receiving or have received any other investigational agents within 30 days of study day 1, or who have previously received MK-2206 at any time
Patient has known active central nervous system (CNS) metastases and/or carcinomatous meningitis; however, patients with CNS metastases who have completed a course of therapy would be eligible for the study provided they are clinically stable for at least 1 month prior to entry as defined as:
History of allergic reactions attributed to compounds of similar chemical or biologic composition to MK-2206
Patients receiving any medications or substances that are inhibitors or inducers of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP450 3A4) are ineligible
Patients with diabetes or in risk for hyperglycemia should not be excluded from trials with MK-2206, but the hyperglycemia should be well controlled on oral agents before the patient enters the trial
Cardiovascular baseline corrected QT by Fridericia's (QTcF) > 450 msec (male) or QTcF > 470 msec (female) will exclude patients from entry on study
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with MK-2206
Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible
No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years
