A Fixed-Sequence, Open-Label Study to Determine the Activity of SCH 717454 as Assessed by Positron Emission Tomography in Subjects With Relapsed or Recurrent Colorectal Cancer

Detailed Summary

The purpose of this study was to determine the activity of two doses of robatumumab (SCH 717454, MK-7454) in participants with relapsed or recurrent colorectal cancer. The primary study hypothesis was that decreases in Positron Emission Tomography (PET)-assessed tumor glucose metabolism (i.e., fluorodeoxyglucose \[FDG\] standardized uptake value \[SUV\]) following administration of 10 mg/kg robatumumab will exceed those following administration of 0.3 mg/kg robatumumab in participants with relapsed or recurrent colorectal cancer who had progressed after first-line chemotherapy. Investigator choices of standard chemotherapy: irinotecan as a single agent +/- cetuximab OR capecitabine as a single agent, OR FOLFOX (leucovorin calcium \[folinic acid\]\[FOL\] + fluorouracil \[F\] + oxaliplatin \[OX\]) OR CAPEO(capecitabine \[CAPE\] or Xeloda® \[XEL\] + oxaliplatin \[OX\]) OR FOLFIRI (leucovorin calcium \[folinic acid\]\[FOL\] + fluorouracil \[F\] + irinotecan \[IRI\]) +/- cetuximab OR cetuximab as a single agent.
