A Study of Irinotecan and Cetuximab With or Without IMC-A12 for Treatment of Participants With Colon or Rectum Cancer Who Got Worse After Their First Treatment With Oxaliplatin and Bevacizumab

Phase 2

Terminated

• Conditions: Colon Cancer; Rectal Cancer
• Interventions: Biological: Cetuximab; Drug: Irinotecan; Biological: IMC-A12 (cixutumumab)

• Registration Number: NCT00845039
• Lead Sponsor: Eli Lilly and Company

Brief Summary

The purpose of this study is to determine the value of adding IMC-A12 to irinotecan and cetuximab in participants with metastatic colorectal cancer (CRC).

Detailed Description

The purpose of this study is to determine the value of adding IMC-A12 to irinotecan + cetuximab in improving progression-free survival (PFS) at 18 weeks from the date of randomization for participants with metastatic Kirsten Rat Sarcoma (K-RAS) wild-type CRC that has progressed on an oxaliplatin/bevacizumab-containing regimen.

Recruitment & Eligibility

• Status: TERMINATED
• Sex: All
• Target Recruitment: 4

Inclusion Criteria

• Must consent to be in the study and must have signed and dated Institutional Review Board (IRB)-approved consent forms conforming to federal and institutional guidelines for the pre-entry tumor sample submission for central K-RAS testing and for the study treatment
• Must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
• Must have metastatic CRC
• The CRC tumor or metastatic tumor must be v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog gene (K-RAS) wild-type as determined by central testing
• Must be documented disease progression during first-line therapy containing both oxaliplatin and bevacizumab
• Most recent treatment regimen must have ended ≥21 days prior to randomization, and clinically significant side effects associated with previous therapy must have resolved to ≤Grade 1 with the exception of neuropathy which must have resolved to ≤Grade 2
• Imaging of the chest, abdomen and pelvis with computed tomography (CT) scan or magnetic resonance imaging (MRI) must be performed within 3 weeks prior to randomization
• Must have measurable disease, defined as at least 1 lesion outside a previous radiation therapy (RT) field that can be accurately measured in at least 1 dimension as ≥20 millimeters (mm) with conventional techniques or as ≥10mm with 5mm cuts using a spiral CT scan
• Evidence of adequate bone marrow function: absolute neutrophil (ANC) ≥1200 cubed millimeters (mm³), hemoglobin ≥9 grams per deciliter (g/dL), platelets ≥100,000 mm³
• Evidence of adequate hepatic function. If no liver metastases: aspartate aminotransferase (AST) ≤2.5 times (x) upper limit of normal (ULN), total bilirubin ≤1.5 x ULN for the lab. In the presence of liver metastases: AST ≤5.0 x ULN, total bilirubin ≤1.5 x ULN for the lab
• Serum creatinine must be ≤1.5 x ULN for the lab
• Must have a fasting blood glucose <126 milligrams/deciliter (mg/dL). Fasting is defined as no caloric intake for at least 8 hours

Exclusion Criteria

• Life expectancy less than 12 weeks
• Diagnosis of anal or small bowel carcinoma
• Tumor that is considered by the surgeon to be amenable to complete resection
• Previous RT to >25% of bone marrow
• RT to sites of measurable disease chosen as target lesions
• Radiological evidence and/or clinical signs or symptoms of central nervous system (CNS) metastases
• Any of the following conditions and events: uncontrolled hypertension, defined as systolic blood pressure (BP) >150 millimeters of mercury (mmHg) or diastolic BP >100 mmHg with or without antihypertensive medication (participants with hypertension that is well-controlled on medication are eligible); unstable angina within 6 months before randomization; New York Heart Association (NYHA) Class III or IV cardiac disease; myocardial infarction (MI) within 6 months before randomization; symptomatic arrhythmia; CNS cerebrovascular ischemia [transient ischemic attack (TIA) or stroke] within 6 months before randomization
