A Study to Determine the Activity of Robatumumab (SCH 717454, MK-7454) in Participants With Relapsed or Recurrent Colorectal Cancer (P04721, MK-7454-003)

• Status: Completed
• Trial end date: 2009-06-04
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
