Generic (Regorafenib) Reganni

Regorafenib, sold under the brand name Reganni,Stivarga among others, is an oral multi-kinase inhibitor developed by Bayer which targets angiogenic, stromal and oncogenic receptor tyrosine kinase (RTK). Regorafenib shows anti-angiogenic activity due to its dual targeted VEGFR2-TIE2 tyrosine kinase inhibition. Since 2009 it was studied as a potential treatment option in multiple tumor types. By 2015 it had two US approvals for advanced cancers.

Why is this medication prescribed?
Regorafenib is used to treat colon and rectal cancer (cancer that begins in the large intestine or the rectum) that has spread to other parts of the body in people who have not been treated successfully with certain other medications. It is also used to treat gastrointestinal stromal tumors (GIST; a type of tumor that grows in the stomach, intestine [bowel], or esophagus [tube that connects the throat with the stomach]) in people who were not treated successfully with certain other medications. Regorafenib is also used to treat hepatocellular carcinoma (HCC; a type of liver cancer) in people who were previously treated with sorafenib (Nexafar). Regorafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps to slow or stop the spread of cancer cells.
