Panitumumab and Chemotherapy in Patients With Advanced Colorectal Cancer After Prior Therapy With Bevacizumab

A Phase II Study of Panitumumab in Combination With FOLFIRI After Progression on FOLFIRI Plus Bevacizumab in KRAS(Kirsten Rat Sarcoma) and NRAS Wild-Type Metastatic Colorectal Cancer.

This phase II trial studies how well panitumumab and combination chemotherapy works in treating patients with metastatic colorectal cancer previously treated with combination chemotherapy and bevacizumab. Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panitumumab and combination chemotherapy together may kill more tumor cells

Study Overview

• Conditions: Mucinous Adenocarcinoma of the Rectum; Signet Ring Adenocarcinoma of the Rectum; Mucinous Adenocarcinoma of the Colon; Signet Ring Adenocarcinoma of the Colon; Stage IV Colon Cancer; Stage IV Rectal Cancer; Recurrent Colon Cancer; Recurrent Rectal Cancer
• Intervention / Treatment: Biological: panitumumab; Drug: irinotecan hydrochloride; Drug: fluorouracil; Drug: leucovorin calcium

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the median progression-free survival in patients treated with leucovorin calcium, fluorouracil, and irinotecan hydrochloride (FOLFIRI) and panitumumab for K-ras and NRAS wild-type, metastatic colorectal carcinoma who have already progressed on FOLFIRI + Bevacizumab.

SECONDARY OBJECTIVES:

I. To determine the frequency and severity of toxicities of the regimens. II. To determine overall response rate. III. To determine the median overall survival and the overall survival rate at 1 year.

OUTLINE:

Patients receive panitumumab intravenously (IV) over 60-90 minutes, leucovorin calcium IV over 90 minutes, fluorouracil IV continuously over 46 hours, and irinotecan hydrochloride IV over 90 minutes on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

• Patients with advanced adenocarcinoma of the colon or rectum not curable with surgery or radiotherapy and have been previously treated for their disease with FOLFIRI plus bevacizumab in the first line metastatic setting; patients will only be eligible if their last line of therapy prior to enrolling onto the study was FOLFIRI and bevacizumab received no more than 6 months prior to enrolling in this study; they should have been treated with FOLFIRI plus bevacizumab until disease progression is radiographically documented
• Patients' tumors will need to tested for the K-RAS and N-RAS mutation status; only those patients with wild-type or unmutated K-RAS and N-RAS oncogene are eligible to participate in this study
• Provide written informed consent prior to study-specific screening procedures, with the understanding that the patient has the right to withdraw from the study at any time, without prejudice

• Magnesium >= lower limit of normal
• Measurable disease is required according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria
• The effects of Panitumumab on the developing human fetus are unknown; for this reason and because monoclonal antibodies as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and up to 6 months after completing therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

Exclusion Criteria:

• Pregnant or lactating women; women of childbearing potential with either a positive or no pregnancy test at baseline; woman or men of childbearing potential not using a reliable and appropriate contraceptive method; (postmenopausal woman must have been amenorrheic for at least 12 months to be considered of non-childbearing potential)
• Sexually active males unwilling to practice contraception during the study and 6 months beyond
• Uncontrolled intercurrent illness including but not limited to clinically significant cardiac disease not well controlled with medication (e.g. congestive heart failure, symptomatic coronary artery disease and cardiac arrhythmias) or myocardial infarction within the last 12 months, and serious concurrent infections
• History of interstitial lung disease (eg, pneumonitis or pulmonary fibrosis) or evidence of interstitial lung disease on baseline chest computed tomography (CT) scan
• KRAS or NRAS mutant tumors
• Active inflammatory bowel disease or other bowel disease causing chronic diarrhea (defined as >= Common Toxicity Criteria [CTC] grade 2 [Common Terminology Criteria for Adverse Events (CTCAE) version 4.0])
