CLIME: Study of Cetuximab in Combination With mFOLFOX-6 (Oxaliplatin, Leucovorin, 5-FU) to Treat Colorectal Liver Metastatic Cancer Patients
Study Details
Study Description
Brief Summary
The aim of this study is to explore whether cetuximab in combination with mFOLFOX6 as treatment could improve the resection rate in patients with KRAS wild-type, unresectable liver metastases of mCRC.

Detailed Description
During the last decade, chemotherapy in metastatic colorectal cancer (mCRC) has made considerable progress.However, approximately 25% of patients with colorectal cancer present with overt metastatic disease. In selected patients, synchronous or metachronous liver metastases (LM) can be resected in curative intention. Over the last 5 years there has been the recognition that preoperative, neoadjuvant, combination chemotherapy regimens, namely, 5-fluorouracil/folinic acid (5-FU/FA) in combination with either irinotecan or oxaliplatin can facilitate to downsize the initially unresectable LM and make the resection possible. The addition of targeted therapies might render them even more effective.
Due to these results, the investigators hypothesize that cetuximab in combination with mFOLFOX6 as treatment in patients with KRAS wild-type, unresectable liver metastases of mCRC may further improve clinical outcomes.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or female 18-75 years of age

(Patients should be evaluated by a multidisciplinary team of three local surgeons and one local radiologist, including surgical consultation for potentially resectable patients on the basis of remaining liver volume, infiltration of all liver veins, infiltration of both liver arteries, both portal branches or both bile ducts.)
-
Tumor tissue (primary or metastasis) genotypologically classified as KRAS wild-type in codon 12 and codon 13 of the KRAS gene exon 2
-
No prior chemotherapy (except adjuvant chemotherapy with an interval of ≥ 6 months)
-
Presence of at least one index lesion of hepatic metastasis measurable by CT scan or MRI, not in an irradiated area
-
Neutrophils ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, and hemoglobin ≥ 8 g/dL
-
Bilirubin level ≤ 1.0 x ULN
-
AST and ALT < 1.5 x ULN
-
Serum creatinine ≤ 1.0 x ULN
-
Life expectancy of ≥ 3 months
-
Male or female of child-bearing period should have effective contraception
-
Signed written informed consent
Exclusion Criteria:
-
Any investigational agent(s) within 4 weeks prior to entry
-
Previous exposure to EGFR-targeting therapy
-
Any evidence of extrahepatic metastases and/or primary tumor recurrence

-
Known drug abuse/ alcohol abuse
-
Known dihydropyrimidine dehydrogenase (DPD) deficiency
