Clinical And Translational Study Of MK-2206 In Patients With Metastatic KRAS-Wild-Type, PIK3CA-Mutated, Colorectal Cancer
A Phase II Clinical And Translational Study Of MK-2206 In Patients With Metastatic KRAS-Wild-Type, PIK3CA-Mutated, Colorectal Cancer

The purpose of this study is to test a new drug called MK-2206 for metastatic colorectal cancer. This drug is being tested in a subgroup of patients with colorectal cancer whose tumors have changes in certain genes that may make them more likely to respond to this new medication. As tumors develop, the cells within the tumor acquire mutations within genes, allowing them to grow more effectively. We will be testing your tumor for mutations involving two genes - KRAS and PIK3CA. Patients whose tumors have a normal copy of the KRAS gene and a mutation within the PIK3CA gene will be eligible to participate in this study.

This study is a phase 2 study. The goal of a phase 2 study is to find out what effects, good and/or bad, a new treatment has against a certain type of cancer.

Phase 2
Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Colon Cancer
  • Rectal Cancer
Drug: MK-2206
Patients will receive MK-2206 orally in a once weekly dose of 200mg. There will be no dose escalation. Patients will be treated until disease progression or unacceptable side effects.
Experimental: MK-2206
This will be a single-arm, phase II study of the AKT inhibitor MK-2206 in patients with KRAS-wild-type, PIK3CA-mutated, colorectal cancer whose tumors have progressed through standard chemotherapy regimens.

  • Fasting serum glucose ≤120 mg/dl
  • HBA1C ≤8%
  • Potassium in normal range
  • The patient has a tumor that has wild type KRAS (absence of mutations at codons 12 or 13), and mutant PIK3CA (presence of mutations in exons 20 or 9).
  • Female patient of childbearing potential who are not surgically sterilized must have a negative serum or urine pregnancy test β-hCG within 72 hours prior to receiving the first dose of study medication.
  • Patient, or the patient's legal representative, has voluntarily agreed to participate by giving written informed consent.
  • Patient is able to swallow capsules and has no surgical or anatomical condition that will preclude the patient from swallowing and absorbing oral medications on an ongoing basis.

Exclusion Criteria:

  • Patient who has had chemotherapy, radiotherapy, or biological therapy within 3 weeks (6 weeks for nitrosoureas or mitomycin C), or who has not recovered from the adverse events due to previous agents administered more than 4 weeks prior to Study Day 1. If the patient has residual toxicity from prior treatment, toxicity must be ≤ Grade 1.

  • Clinically significant congestive heart failure, unstable angina pectoris,
  • Clinically significant cardiac arrhythmia,
