Summary

The purpose of this adaptive trial is to compare the progression-free survival of participants with metastatic rectal carcinoma when treated with intravenous (IV) dalotuzumab (MK-0646) + irinotecan therapy relative to participants treated with IV cetuximab + irinotecan. The primary hypothesis is that administration of dalotuzumab in combination with irinotecan to participants with wild-type KRAS metastatic rectal carcinoma with high insulin growth factor (IGF)-1/low IGF-2 expression levels improves progression-free survival compared to patients treated with cetuximab in combination with irinotecan.

Conditions

  • Rectal Neoplasms

Interventions

DRUG

Dalotuzumab

Dalotuzumab will be administered intravenously after the completion of irinotecan infusion at a dose of 10 mg/kg once weekly.

DRUG

Irinotecan

Irinotecan 180 mg/m\^2 will be administered intravenously once every two weeks either prior to dalotuzumab (Arm A) or after cetuximab (Arm B). Pre-medication at the discretion of the investigator will follow local or country-specific standard of care.

DRUG

Cetuximab

Cetuximab will be administered intravenously prior to irinotecan at an initial dose of 400 mg/m\^2 followed by weekly infusions of 250 mg/m\^2. Pre-medication at the discretion of the investigator will follow local or country-specific standard of care.
