Regorafenib Powder Description

Regorafenib powder is an oral multi-kinase inhibitor which targets angiogenic, stromal and oncogenic receptor tyrosine kinase (RTK). Regorafenib powder 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.

Regorafenib powder is a targeted therapy that targets and binds to tyrosine kinase receptors and inhibits epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF), receptors on the surface of the cell. By binding to these receptors regorafenib powder blocks an important pathway that promotes cell division.

 

Regorafenib Powder Mechanism of Action

Regorafenib powder is a small molecule inhibitor of multiple membrane-bound and intracellular kinases involved in normal cellular functions and in pathologic processes such as oncogenesis, tumor angiogenesis, and maintenance of the tumor microenvironment. In in vitro biochemical or cellular assays, regorafenib powder or its major human active metabolites M-2 and M-5 inhibited the activity of RET, VEGFR1, VEGFR2, VEGFR3, KIT, PDGFR-alpha, PDGFR-beta, FGFR1, FGFR2, TIE2, DDR2, TrkA, Eph2A, RAF-1, BRAF, BRAFV600E , SAPK2, PTK5, and Abl at concentrations of regorafenib powder that have been achieved clinically. In in vivo models, regorafenib powder demonstrated anti-angiogenic activity in a rat tumor model, and inhibition of tumor growth as well as anti-metastatic activity in several mouse xenograft models including some for human colorectal carcinoma.

 

Regorafenib Powder Application

Regorafenib powder is a targeted cancer drug. You might have it as a treatment for:

▪ Gastro intestinal stromal cancer (GIST) – a rare type of soft tissue sarcoma of the stomach or intestines;

▪ Advanced cancer that started in the liver (primary liver cancer).
