|Exelixis Signs Co-Development Agreement With Genentech for Small Molecule Oncology Compound|
New Collaboration Focuses on Novel Compound Targeting MEK
SOUTH SAN FRANCISCO, Calif., Jan. 3 /PRNewswire-FirstCall/ -- Exelixis, Inc. (Nasdaq: EXEL) today announced that it has entered into an agreement with Genentech, Inc. for the worldwide co-development of XL518, a small-molecule inhibitor of MEK. Exelixis submitted an Investigational New Drug application (IND) for XL518 to the U.S. Food and Drug Administration (FDA) on December 20, 2006. MEK, also known as mitogen activated protein kinase (MAPK) kinase, is a key component of the RAS/RAF/MEK/ERK pathway, which is frequently activated in human tumors. Inappropriate activation of the MEK/ERK pathway can promote cell growth in the absence of exogenous growth factors.
Under the terms of the agreement, Exelixis will receive upfront and milestone payments totaling $40 million upon signing of the agreement and with the submission of the IND for XL518 to the FDA. Exelixis is responsible for developing XL518 through the end of Phase I. If Genentech exercises its option to further develop XL518, Exelixis will receive an additional payment and Genentech will be responsible for further development, including all further development costs. Exelixis has the option to co-promote in the United States along with Genentech. Exelixis has a substantial share in the marketing and commercialization costs, as well as an initial equal share in profits in the United States, which will decrease as sales increase. Exelixis will receive royalties on any sales of the product which may be commercialized outside the United States.
"Genentech is a leading innovator of important new cancer therapies, and we believe that this collaboration validates the significant potential of XL518 to be the first in a new class of drugs targeting critical intracellular signaling pathways," said George A. Scangos, Ph.D., president and chief executive officer of Exelixis. "This collaboration also combines our world class drug discovery and development platform with Genentech's proven track record in commercializing novel compounds that positively impact the lives of patients with cancer. This is our second strategic collaboration with Genentech, and we look forward to strengthening our relationship with Genentech on the development of this promising compound."
