| Novel Method of Treating Cancer Using Ixolaris |
Description of Invention:
Aggressive tumors spread between tissues in a process known as metastasis. Tumor metastasis, particularly with regard to brain cancer (gliomas), has been linked to the aberrant expression of membrane-bound tissue factor (TF). TF normally functions as a blood coagulation factor and can lead to the production of pro-angiogenesis factors such as vascular endothelial growth factor (VEGF). By doing this in the vicinity of tumors, TF may enhance both tumor growth and the ability of tumors to metastasize.
Ixolaris is a protein that prevents the initiation of blood coagulation, specifically by inhibiting TF. NIH inventors have explored the possibility that Ixolaris could be effective as an anti-cancer therapy. As an inhibitor of TF, Ixolaris could potentially inhibit the function of TF, thereby reducing the ability of a tumor to develop and to metastasize. Recent data show that Ixolaris has the ability to prevent tumor growth in vivo using mouse xenograft models. Importantly, the inhibition in vivo occurred without noticeable bleeding. Since Ixolaris is not immunogenic, it might be an excellent candidate as an anti-cancer therapeutic.
Applications:
Treatment and prevention of tumor growth and metastasis by inhibiting TF and blood vessel formation

Provides a novel mechanism for preventing tumor metastasis
