Curis recently received a US patent (US Patent Number 8,324,240) entitled 'Fused Amino Pyridine as HSP90 Inhibitors.' It covers a genus of compounds that includes Debio 0932, an orally-administered Heat Shock Protein 90, or HSP90, inhibitor, which is being developed by Curis's licensee Debiopharm:
• HSP90 is a chaperone protein that controls the folding and processing of certain client proteins. HSP90 clients include many proteins that drive tumor 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 tumor retention, blood-brain-barrier penetration, and promising anti-tumor activity both as monotherapy and in combination against a broad range of tumors in preclinical models. Debiopharm presented data from the dose escalation portion of an ongoing Phase I clinical trial study. Debio 0932 was generally well tolerated in this study and showed promising signs of anti-tumor activity in patients with advanced solid tumors, especially lung cancer.
"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 CEO.
"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."
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.
