Exelixis, Inc.

Drug Names(s): XL418

Description: XL418 is a small molecule that inhibits the activity of protein kinase B (PKB or AKT) and S6 Kinase (S6K), which act downstream of phosphoinosotide-3 kinase (PI3K). Activation of these kinases is a frequent event in human tumors, promoting cell growth, survival, and resistance to chemotherapy and radiotherapy. Inactivation of the pathway through inhibition of AKT is expected to induce apoptosis in tumor cells. AKT inhibitors may also sensitize tumor cells to a wide range of chemotherapy.

Deal Structure: GlaxoSmithKline and Exelixis have a partnership focused on the collaboration in 12 programs (XL784, XL647, XL999, XL880, XL184, XL820, XL844, XL281, XL418, XL228 and two earlier stage oncology programs). GlaxoSmithKline has the right to select from these programs up to two compounds at proof-of-concept (completion of Phase IIa clinical trial) or three compounds if GlaxoSmithKline extends the collaboration.

Partners: GlaxoSmithKline plc
