PRIME: Panitumumab Randomized Trial In Combination With Chemotherapy for Metastatic Colorectal Cancer to Determine Efficacy

A Randomized, Multicenter, Phase 3 Study to Compare the Efficacy of Panitumumab in Combination With Oxaliplatin/ 5-fluorouracil/ Leucovorin to the Efficacy of Oxaliplatin/ 5-fluorouracil/ Leucovorin Alone in Patients With Previously Untreated Metastatic Colorectal Cancer

The purpose of this study is to determine the treatment effect of panitumumab in combination with FOLFOX compared to FOLFOX alone as first line therapy for metastatic colorectal cancer

Inclusion Criteria:

• Man or woman at least 18 years old
• Diagnosis of metastatic colorectal cancer
• At least 1 uni-dimensionally measurable lesion of at least 20 mm per modified RECIST

• Paraffin-embedded tumor tissue from the primary tumor or metastasis available for central analyse Exclusion Criteria:
• History or known presence of central nervous system (CNS) metastases
• History of another primary cancer, except: Curatively treated in situ cervical cancer, or Curatively resected non-melanoma skin cancer, or Other primary solid tumor curatively treated with no known active disease present and no treatment administered for ≥ 5 years before randomization
• Prior chemotherapy or systemic therapy for the treatment of metastatic colorectal carcinoma except: adjuvant fluoropyrimidine-based chemotherapy or prior fluoropyrimidine therapy administered solely for the purpose of radiosensitization
• Prior oxaliplatin therapy
• Prior anti-epidermal growth factor receptor (EGFr) antibody therapy (eg, cetuximab) or treatment with small molecule EGFr inhibitors (eg, erlotinib)
• Clinically significant cardiovascular disease (including myocardial infarction, unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia) 1 year prior to randomization History of interstitial lung disease (eg, pneumonitis or pulmonary fibrosis) or evidence of interstitial lung disease on baseline chest computed tomography (CT) scan
