Study to Evaluate the Effects of Sorafenib if Combined With Chemotherapy (FOLFOX6 or FOLFIRI) in the Second-Line Treatment of Colorectal Cancer

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether sorafenib in combination with chemotherapy has a positive effect on time to progression of the tumor or death for the treatment of large bowel cancer that has already progressed during a first chemotherapy.

Detailed Description
-----------------
Patients with metastatic CRC who received a first-line therapy with an Oxaliplatin- or Irinotecan based Fluoropyrimidine containing regimen ± bevacizumab and had a progression subsequently, are eligible for this study. Patients will be randomized to receive chemotherapy (FOLFOX6 or FOLFIRI) + sorafenib 400 mg bid or chemotherapy + placebo. Patients who have received an Oxaliplatin based Fluoropyrimidine containing regimen in first-line will obtain FOLFIRI during this study. Patients who have received an Irinotecan based Fluoropyrimidine containing regimen in first-line will obtain FOLFOX6. Primary objective of the study is to compare the Progression-free-survival (PFS) between patients receiving chemotherapy (FOLFOX6 or FOLFIRI) + sorafenib with chemotherapy + placebo.

Eligibility Criteria
-----------------
Inclusion Criteria: Age > 18 years. ECOG Performance Status of 0 to 2 Life expectancy of at least 12 weeks. Subjects with at least one uni-dimensional (RECIST) measurable lesion of metastatic colorectal carcinoma after first-line chemotherapy with an Oxaliplatin- or Irinotecan based Fluoropyrimidine containing regimen ± bevacizumab and had a progression subsequently. Lesions must be measured by CT-scan or MRI.

Peripheral sensory neuropathy > CTC grade 2 Chronic inflammatory bowel disease; ileus; genetic fructose intolerance Pregnant or breast-feeding patients. Women of childbearing potential must have a negative pregnancy test performed within 7 days before the start of treatment. Fertile women and men (<2 years after last menstruation in women) must use effective means of contraception (intrauterine contraceptive device, contraceptive implants, injectables (hormonal depot), transdermal hormonal contraception (contraceptive patch), sexual abstinence or vasectomised partner) during treatment and for at least 6 months after last administration of medication. Substance abuse, medical, psychological or social conditions that may interfere with the patients participation in the study or evaluation of the study results Any condition that is unstable or could jeopardize the safety of the patient and their compliance in the study 18. Patients unable to swallow oral medications. Any other anticancer chemotherapy or immunotherapy during the study or within 4 weeks of study entry. Radiotherapy during study or within 3 weeks of start of study drug. (Palliative radiotherapy will be allowed). Major surgery within 4 weeks of start of study Autologous bone marrow transplant or stem cell rescue within 4 months prior to study treatment Use of biologic response modifiers, such as G-CSF, within 3 week of study entry. [G-CSF and other hematopoietic growth factors may be used in the management of acute toxicity such as febrile neutropenia when clinically indicated or at the discretion of the investigator, however, they may not be substituted for a required dose reduction.] [Patients taking chronic erythropoietin are permitted provided no dose adjustment is undertaken within 2 months prior to the study or during the study] Investigational drug therapy outside of this trial during or within 4 weeks of study entry Prior exposure to the study drug. Any St. John´s wort containing remedy
