LEXINGTON, Mass., Dec. 6, 2012 (GLOBE NEWSWIRE) -- Curis, Inc. (Nasdaq:CRIS), a drug development company seeking to develop next generation targeted small molecule drug candidates for cancer treatment, today announced that the U.S. Patent and Trademark Office has issued a patent covering a genus of compounds that includes Debio 0932, an orally-administered Heat Shock Protein 90 (HSP90) inhibitor, which is being developed by Curis' licensee Debiopharm. The newly issued patent, U.S. Patent Number 8,324,240, is entitled "Fused Amino Pyridine as HSP90 Inhibitors."

"We believe that this patent issuance recognizes the novelty of Debio 0932, a molecule that was invented internally by Curis scientists," stated Dan Passeri, Curis' President and Chief Executive Officer. "We have been pleased with Debiopharm's development efforts and the clinical data generated to-date. We look forward to additional data from this promising molecule, as Debiopharm is currently testing Debio 0932 in a Phase I/II clinical trial in combination with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) as well as in a Phase Ib clinical study in patients with solid tumors, including NSCLC. Debiopharm also intends to initiate a separate Phase I/II clinical trial with Debio 0932 in combination with Everolimus in patients with renal cell carcinoma in the second half of 2013."

About Debio 0932

HSP90 is a chaperone protein that controls the folding and processing of certain client proteins. HSP90 clients include many proteins that drive tumour development and progression, such as EGFR, HER2, c-MET, AKT, KIT, FLT3, and VEGFR. Inhibition of HSP90 leads to degradation of client proteins targeting multiple oncogenic signaling pathways.

Debio 0932 is an oral second-generation HSP90 inhibitor, which has shown extended tumour retention, blood-brain-barrier penetration, and promising anti-tumour activity both as monotherapy and in combination against a broad range of tumours in pre-clinical models. Debiopharm presented data from the dose escalation portion of an ongoing Phase I clinical trial study at the annual meeting of the American Society of Clinical Oncology in June 2012. Debio 0932 was generally well tolerated in this study and showed promising signs of anti-tumour activity in patients with advanced solid tumours, especially lung cancer.

In preclinical testing Debio 0932 demonstrated potent anti-proliferative activity against a broad range of cancer cell lines, including many NSCLC cell lines which are resistant to SOC agents. Debio 0932 potently inhibits tumor growth in subcutaneous xenograft models of a number of solid and hematological malignancies, including models of NSCLC which harbor mutations conferring acquired or primary erlotinib resistance. Furthermore, Debio 0932 is able to extend animal survival in models of brain metastasis due to its ability to cross the blood-brain barrier, and it enhances the activity of several standard-of-care agents in animal models of cancer.
