About this study
Official title: A Controlled Randomized Double-blind Multi-center Phase II Study of FOLFOX6 or FOLFIRI Combined With Sorafenib Versus Placebo in Second-line Metastatic Colorectal Carcinoma
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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sorafenib, Oxaliplatin or Irinotecan and Leucovorin in people with Colorectal Neoplasms, run by AIO-Studien-gGmbH at 57 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 4 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 57 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To compare the PFS between patients receiving chemotherapy (FOLFOX6 or FOLFIRI) + sorafenib with chemotherapy + placebo (time frame: 6 to 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2013.
