Curis Announces Presentation at CHI's ''Discovery on Target: Developing Inhibitors for Promising Drug Targets'' Conference
Curis Presents Preclinical Data on CUDC-101

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Oct. 17, 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 CHI's Discovery on Target: Developing Inhibitors for Promising Drug Targets, which is being held at the World Trade Center in Boston, Massachusetts from October 15-18, 2007.

On October 16, 2007, Curis scientists presented a poster entitled "Potent Anti-Cancer Activity In Vitro and In Vivo by a Novel, Small Molecule Inhibitor of HDAC, EGFR and Her2" during a Poster Session. This presentation included in vivo efficacy and pharmacodynamic preclinical study results of CUDC-101, Curis' proprietary small molecule drug candidate. CUDC-101 is an HDAC, EGFR and Her2 inhibitor, which displays potency improvements over FDA-approved EGFR and EGFR/Her2 inhibitors as well as over a FDA-approved HDAC inhibitor in multiple cell lines across several cancer types including lung, breast, prostate, colon, liver, pancreas and others. Curis believes that CUDC-101 is the first single agent under development to simultaneously inhibit HDAC, EGFR and Her2, three clinically validated cancer targets.

At the CHI meeting, Curis presented CUDC-101 in vivo data, which demonstrated that administration of CUDC-101 results in the inhibition of in vivo growth of various human cancers in standard mouse tumor xenograft models. In these xenograft models, human cancer cells are transplanted into the mouse and allowed to grow into established tumors, at which point Curis scientists intravenously administer CUDC-101. In these cancer xenograft models, CUDC-101 has been demonstrated to inhibit HDAC, EGFR and Her2 in a manner similar to that previously observed in Curis' in vitro studies. In addition, in vivo efficacy observed in these mouse xenograft models is proportionate to the dose administered.

Curis researchers also presented data showing that the administration of CUDC-101 in xenograft models results in inhibition of tumor cell proliferation as well as an increase in apoptosis, or programmed cell death. The poster presentation included data demonstrating that, after treatment with CUDC-101, tumor regression has been observed in two non-small cell lung cancer tumor models which have been reported in third-party publications as sensitive to EGFR inhibitors. Tumor regression has also been observed in a liver cell xenograft cancer model.

Data was also presented demonstrating that tumor inhibition effects of CUDC-101 have also been observed in two non-small cell lung cancer xenograft tumor models that have been reported in third-party publications as insensitive or resistant to the marketed EGFR or EGFR/Her2 inhibitors. Curis believes that this is particularly important since overcoming drug resistance observed with existing EGFR and/or EGFR/Her2 inhibitors or having the ability to treat cancers that are not effectively treated by these existing drugs could, assuming that CUDC-101 clinical evaluations are successful, provide a significant benefit to cancer patients as well as provide a broad market opportunity to Curis.

"We continue to generate meaningful CUDC-101 data that support our ongoing belief that CUDC-101 is a promising clinical candidate and may prove to be beneficial in treating cancer patients," Daniel R. Passeri, President and Chief Executive Officer, stated. "We have recently initiated IND-enabling toxicology studies and continue to work towards seeking to file an IND for CUDC-101 during the first quarter of 2008."
