Objectives:
Primary Objectives:
-
Phase I: Determine the maximal tolerated dose (MTD) of MK-0646 in combination with gemcitabine or gemcitabine plus erlotinib and recommended phase II dose.
-
Phase II:
- Assess progression-free survival (PFS) with a) gemcitabine plus MK-0646 b) gemcitabine plus erlotinib plus MK-0646 and c) gemcitabine plus erlotinib.
- Explore IGF1 tissue level as a predictive biomarker for MK-0646 therapy in phase II expansion cohort.
Secondary Objectives:
- Assess overall response rate (ORR), treatment toxicity, and overall survival (OS) with the addition of MK-0646 to gemcitabine or gemcitabine plus erlotinib.
- Correlate PFS and OS with IGF-1, IGFBP-3 levels and the expression of p-IRS, IGF-1R, EMT biomarkers, Akt, Erk, mTOR, and PI13k in tumor cells.
- To assess the incidence of single nucleotide polymorphisms of the IgF1R pathway related genes (IGF1, IGF1R, IRS1 and IRS2). These genotypes will be correlated with the clinical endpoints of this study, including OS, ORR and PFS.
Full description
Phase I
The Study Drugs:
MK-0646 is designed to block proteins that are thought to cause cancer cells to grow and spread. This drug may help slow the growth of tumors.
Gemcitabine is designed to disrupt the growth of cancer cells, which may cause cancer cells to die.
Erlotinib hydrochloride is designed to block the activity of a protein found on the surface of many tumor cells that may control the growth and survival of cancer cells. This may stop cancer cells from growing.
Study Drug Dose Level and Groups:
If you are found to be eligible to take part in this study, you will be assigned to a group (Arm A or Arm B) based on when you joined the study, how many participants have been enrolled before you, and on the safety data that is available at that time.
- If you are in Arm A, you will receive MK-0646 and gemcitabine.
- If you are in Arm B, you will receive MK-0646, gemcitabine, and erlotinib hydrochloride.
There are 2 dose levels of MK-0646 in each arm. There will be 3-6 participants enrolled in each dose level in each arm. Enrollment will begin in Arm A. Arm B will use the same 2 dose levels as Arm A. If the first dose level of Arm A is found to be tolerable, at least 3 patients will be enrolled in Arm B, Level 1, and then at least 3 patients will be enrolled in Arm A, Level 2. If Arm B, Level 1 and Arm A, Level 2 can be safely given, the last group of 3-6 patients will be enrolled in Arm B, Level 2. The first group of participants in each arm will receive the lower dose level. The next group in each arm will receive a higher dose than the first group, if no intolerable side effects were seen.
The dose of gemcitabine and/or erlotinib hydrochloride will be the same for every group.
Study Drug Administration:
If you are in Arm A, on Days 1, 8, and 15 of each 28-day study cycle, you will receive gemcitabine through a needle into your vein over about 1 1/2 hours. On Days 1, 8, 15, and 22 of each cycle, you will receive MK-0646 by vein over 1 hour.
If you are in Arm B, you will take erlotinib hydrochloride by mouth once a day (in the morning) every day. You should take it with about 1 cup (8 oz.) of water 1 hour before or 2 hours after eating. On Days 1, 8, and 15 of each cycle, you will receive gemcitabine by vein over about 1 1/2 hours. On Days 1, 8, 15, and 22 of each cycle, you will receive MK-0646 by vein over 1 hour.
Depending upon how well you tolerate gemcitabine, your doctor may decide that you should receive gemcitabine on Days 1 and 15 instead of Days 1, 8, and 15.
Study Visits:
On Day 1 of Cycle 1, the following tests and procedures will be performed:
- Your medical history will be recorded.

Exclusion criteria
- Prior systemic chemotherapy or biological therapy for metastatic disease
- Prior exposure to IGF-1R inhibitors.
- Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to the agents used in the 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.
