Curis Announces Presentation at the 2007 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Oct. 25, 2007--Curis, Inc. (NASDAQ: CRIS), a drug development company focused on seeking to develop proprietary targeted medicines primarily for cancer treatment, today announced a presentation at the 2007 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, which is being held at the Moscone Convention Center in San Francisco, California.

On October 24, 2007, Curis scientists presented a poster entitled "CUDC-101, a Synthetic and Potent HDAC, EGFR and Her2 Inhibitor, Effectively Inhibits Proliferation of Cancer Cell Lines" during a poster session. This presentation included discussions of a potential mechanism of action and the anticancer properties of CUDC-101, Curis' proprietary small molecule drug candidate that Curis believes is the first single agent under development that simultaneously targets HDAC, EGFR and Her2, three validated cancer targets.

The poster presentation also included data which supports a potential mechanism of action for CUDC-101. Many cancers either display resistance to the marketed EGFR and EGFR/Her2 inhibitors or become resistant with time, which has resulted in continued development efforts to find more effective anticancer drugs. Published third-party data suggests that cancer cells often utilize the Her3, c-MET and Akt survival pathway to escape death from these marketed EGFR or EGFR/Her2 targeted cancer drugs. CUDC-101 represents a potentially important therapeutic advance in that it mechanistically targets EGFR/Her2 and simultaneously appears to overcome resistance to EGFR and/or Her2 inhibition by epigenetically blocking the alternative survival pathway involving Her3, c-MET and Akt. Curis believes that, by synergistically blocking both HDAC and EGFR/Her2 activity, CUDC-101 may provide for the improved killing of cancer cells by rapidly and durably suppressing several intervention points at the same time. Curis data demonstrates improvements in both in vitro anti-proliferation assays and in efficacy measures against various cell lines in xenograft tumors models.

CUDC-101 has a molecular weight of under 450, which is similar to erlotinib (an EGFR inhibitor) and smaller than lapatinib (an EGFR-Her2 inhibitor). CUDC-101 is 5 to 10-fold more potent than SAHA in HDAC inhibition, 10 to 20-fold more potent than erlotinib in EGFR inhibition and demonstrates similar potency to lapatinib in Her2 inhibition. CUDC-101 displays potency improvements ranging from 3 to 20-fold as compared to the combination of an HDAC inhibitor that is concurrently administered with either an EGFR inhibitor or an EGFR/Her2 reference drug. These potency improvements were observed in 27 cell lines of major cancer types including lung, breast, prostate, colon, liver and pancreas. CUDC-101 also inhibits all three targeted pathways in vivo and has been proven efficacious in various mouse xenograft models of human cancer.

"Our data suggests that Curis' lead drug candidate, CUDC-101, may represent a breakthrough in addressing the rapid emergence of drug resistance in cancer patients currently treated with EGFR and EGFR/Her2 inhibitors," Daniel R. Passeri, MSc., J.D., President and Chief Executive Officer, stated. "These preclinical data are encouraging and we look forward to bringing CUDC-101 towards clinical testing."
