Study Details

Study Description

Brief Summary

PURPOSE:

A primary aim of phase II FOCULM study is to explore whether cetuximab in combination with FOLFOXIRI as first treatment could improve surgical conversion in patients with KRAS/NRAS wild-type, unresectable liver - only metastases of colorectal cancer. The first secondary aim is to evaluate the safety and tolerability of the chemotherapy of FOLFOXIRI plus Cetuximab targeted therapy regimen in this patient population.

Secondary aims include determination of objective response rate, progression free survival, quality of life and time to recurrence for patients undergoing complete resection and/or ablation of liver.

Condition or Disease	Intervention/Treatment	Phase

Detailed Description

Patients will be randomized to two therapy groups:

Ages Eligible for Study:

18 Years to 65 Years

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Signed informed consent obtained before any study specific procedures. Subjects must be able to understand and willing to sign a written informed consent.
Male or female subjects > 18 years < 65 of age
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and must be considered a potential candidate for a major hepatic surgical procedure.
Histological or cytological documentation of adenocarcinoma of the colon or rectum. All other histological types are excluded.
There must be documentation by PET/CT scan, CT scan, MRI, or intraoperative palpation (at the time of resection of the primary colorectal tumor, if applicable) that the patient has evidence of metastases confined to the Liver (Histologic confirmation of hepatic metastasis is not required.). The liver metastases must have been determined by a hepatic surgeon approved to participate in the study to be unresectable based on at least one of the following criteria: All of the liver metastases can not be resected (and/or ablated) with negative margins, i.e., lesion(s) located in an area that would result in the resection of all of the hepatic veins or the main portal vein or the right and left hepatic arteries or the common bile duct; Complete resection and/or ablation would require greater than 60% of the liver parenchyma to be removed.
Patients are eligible with any of the following: primary tumor and regional nodes resected with clear surgical margins and no evidence of extra-hepatic disease or; unresected primary tumor with plans to resect the primary tumor prior to study entry or; unresected primary tumor with plans to resect the primary tumor and the liver metastases in a single surgical procedure performed within 8 weeks after the last preoperative dose of chemotherapy/cetuximab or; unresected primary with plans to resect the primary tumor and the liver metastases in staged procedures performed within 8 weeks after the last preoperative dose of chemotherapy/cetuximab.
