In patients who receive an organ transplant, their body considers this organ as foreign and attempts to destroy it. This is called rejection. All patients who receive an organ transplant, will take a combination of anti-rejection medications. These medications prevent the new organ from being rejected from the body. FTY720 is a new compound that helps prevent organ rejection.
