Description: Debio 0932, also known as CUDC-305, is a novel heat shock protein 90 (HSP90) inhibitor with strong affinity for HSP90 alpha/beta, high oral bioavailability and potent anti-proliferative activity against a broad range of cancer cell lines (with a mean IC50 of 220 nmol/L), including many non-small cell lung cancer (NSCLC) cell lines which are resistant to standard-of-care (SOC) agents. Debio 0932 potently inhibits tumour growth in subcutaneous xenograft models of a number of solid and haematological malignancies, including models of NSCLC which harbour mutations conferring acquired or primary erlotinib resistance.

Additional Information

In vitro antitumor activity: Scientists from Curis, Inc tested the growth inhibitory effects of CUDC-305 against a total of 40 human cancer cell lines, including 34 solid and 6 hematologic tumor–derived lines. CUDC-305 inhibited the proliferation of these cancer cell lines with an IC50, ranging from 40 to 900 nmol/L (mean IC50, 220 nmol/L).  CUDC-305 shows high affinity for HSP90alpha/beta (IC(50), approximately 100 nmol/L) and HSP90 complex derived from cancer cells (IC(50), 48.8 nmol/L). CUDC-305 exhibits high oral bioavailability (96.0%) and selective retention in tumor (half-life, 20.4 hours) compared with normal tissues. Furthermore, CUDC-305 can cross blood-brain barrier and reach therapeutic levels in brain tissue. CUDC-305 exhibits dose-dependent antitumor activity in an s.c. xenograft model of U87MG glioblastoma and significantly prolongs animal survival in U87MG orthotopic model. CUDC-305 also displays potent antitumor activity in animal models of erlotinib-resistant non-small cell lung cancer and induces tumor regression in animal models of MDA-MB-468 breast cancer and MV4-11 acute myelogenous leukemia. Correlating with its efficacy in these various tumor models, CUDC-305 robustly inhibits multiple signaling pathways, including PI3K/AKT and RAF/MEK/ERK, and induces apoptosis. In combination studies, CUDC-305 enhances the antitumor activity of standard-of-care agents in breast and colorectal tumor models. CONCLUSION: CUDC-305 is a promising drug candidate for the treatment of a variety of cancers, including brain malignancies. (source: Clin Cancer Res. 2009 Jun 15;15(12):4046-57.).
