Combination Chemotherapy Treatments in Patients With Metastatic Colorectal Cancer
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This study will examine a new combination of drugs: celecoxib, capecitabine and irinotecan, for the treatment of metastatic colorectal cancer. Capecitabine and irinotecan, individually, are approved by the Food and Drug Administration (FDA) for use in colorectal cancer. The combination of these two drugs is experimental (not approved by the FDA as standard treatment), but is a widely used treatment option and preliminary studies have shown that treatment with the combination of capecitabine and irinotecan has a positive effect on metastatic colorectal cancer. Likewise, previous research in animals has shown that celecoxib, a drug approved for arthritis therapy, also has activity against this tumor type and may improve the anti-cancer activity of the combination of capecitabine and irinotecan.
