Summary

The purpose of this study is to evaluate the safety and tolerability of SF1126 in patients with advanced or metastatic tumors by assessing the dose limiting toxicities (DLTs) and defining the maximum tolerated dose given twice per week for 4 weeks and ultimately define a recommended phase II dose.

Detailed description

SF1126 is a conjugate containing a 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 specific integrins such as αγβ3 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.
