Details and patient eligibility

About

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.

Full 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.

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.

ALT and AST < 2.5 x upper limit of normal (< 5 x upper limit of normal for patients with liver involvement of their cancer)
Alkaline phosphatase < 4 x upper limit of normal
PT-INR/PTT < 1.5 x upper limit of normal [Patients who are being therapeutically anticoagulated with an agent such as coumadin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in these parameters exists.]
Serum creatinine < 1.5 x upper limit of normal
Signed and dated informed consent before the start of specific protocol procedures
