Curis Announces Conclusion of Hedgehog Agonist Collaboration with Wyeth
- Company to Seek New Partner for Development Program -

CAMBRIDGE, Mass. -- Curis, a drug development company focused on developing novel targeted medicines primarily for cancer treatment, today announced that Wyeth has decided that it will no longer pursue its development efforts on the Hedgehog agonist program and will terminate the January 2004 collaboration agreement with Curis. Research efforts under the collaboration have focused on the preclinical development of small molecule and protein Hedgehog agonists, primarily for stroke and cardiovascular indications. Pursuant to the agreement, the collaboration will conclude on May 6, 2008.

“While we are disappointed in Wyeth’s decision to conclude our collaboration, we believe that significant progress has been made on the Hedgehog agonist program through our research with Wyeth. We remain hopeful about the future prospects of the Hedgehog agonist as a potential therapeutic for various diseases and we will seek a new partner to continue advancing this program. Our internal data and third party publications suggest that Hedgehog agonists may provide therapeutic benefit in several disease areas, including neurological, cardiovascular and bone disorders, as well as for wound healing and hair growth,” said Daniel R. Passeri, President and Chief Executive Officer of Curis. “Our focus remains on our core cancer assets and we expect to achieve several key upcoming milestones for these programs, including Genentech’s initiation of Phase II testing of our Hedgehog systemic antagonist in one or more solid tumor indications in 2008 and a near-term IND application for our proprietary targeted cancer drug candidate CUDC-101, a potentially first-in-class small molecule inhibitor of EGFR, Her2 and HDAC.”

About the Wyeth Collaboration

In January 2004, Curis entered into a collaboration agreement with Wyeth Pharmaceuticals under which Curis licensed its Hedgehog protein and novel small molecule Hedgehog pathway agonists to Wyeth. Wyeth paid Curis an up-front license fee and provided research funding through February 2008. Wyeth and Curis had been researching Hedgehog agonists for use in the treatment of stroke and cardiovascular disease under this collaboration.
