About SF1126

SF1126 is the only clinical stage vascular targeted pan-PI3K inhibitor that selectively inhibits all PI3K class I isoforms and other key members of the PI3K superfamily, including mTORC1/2, DNA-PK, PLK-1, CK2, ATM and PIM-1. SF1126 is designed to inhibit both angiogenesis and cell proliferation by targeting and binding to integrins that are expressed on the surface of new tumor vasculature and within the tumor compartment.

In preclinical xenograft models SF1126 has demonstrated broad activity as a single agent; synergy with commonly used chemotherapy agents, targeted agents, and radiation; and has been shown to reverse resistance mediated through the PI3K/PTEN pathway.

About PI3 Kinase

Phosphatidylinositol 3 kinases (PI3K) are involved in one of the major pathways of intracellular signal transduction and are important in controlling cell growth/angiogenesis, differentiation, proliferation and survival/apoptosis. Dysregulation of the PI3 kinase signaling cascades can lead to cancer and aberrant PI3K pathway activity is observed with high frequency in a variety of tumor types. PI3K signaling through its downstream effectors AKT and mTOR is also known to promote tumor cell survival, proliferation, and growth. Dysregulation of PI3K signaling is also thought to contribute resistance to a variety of anticancer therapies. Thus, PI3K is considered a high value target in treating cancer.
