Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/19509149

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. In both laboratory and animal testing, CUDC-305 demonstrated high potency in vitro and/or in vivo across a wide range of cancers. Most notably, Curis scientists observed complete tumor regression following oral administration of CUDC-305 in a mouse xenograft model of acute myelogenous leukemia (AML). Tumor regression has also been observed after treatment of CUDC-305 in mouse xenograft models of breast, non-small cell lung, gastric cancer and glioblastoma brain cancers. In this preclinical testing, the compound also demonstrated an ability to effectively cross the blood brain barrier, and demonstrated an ability to extend survival in an intracranial glioblastoma model. Early stage toxicity studies suggest that CUDC-305 appears to have a better therapeutic window than several leading Hsp90 inhibitors in clinical development.

CNS Activity

Curator's Comment: CUDC-305 can cross blood-brain barrier and reach therapeutic levels in brain tissue.

Sample Use Guides

Gelatin capsules of 2 dosage strengths (25 mg or 100 mg) The maximum dose will depend on the number of dose levels necessary to determine the MTD. CUDC-305 will be administered orally to sequential escalating dose cohorts, as an every-other-day schedule.
Route of Administration: Oral
CUDC-305 strongly bind to cancer-derived HSP90 complex with an IC50 of 61.2 nmol/L in H1975 and 74.2 nmol/L in H1993, respectively. 1 umol/L CUDC-305 reduced the levels of phospho-MET as well as total MET in H1993 and H1975 NSCLC cells

In survival studies in Balb/C nude mice, the highest dose was reduced to 120 mg/kg as a result of the compromised animal condition due to lung and brain tumor implantation surgeries.

ACTIVE MOIETY
NCI Drug Dictionary: debio-0932 An orally active and small molecule inhibitor of heat shock protein 90 (Hsp90) with potential antineoplastic activity. Hsp90 inhibitor Debio 0932 specifically blocks Hsp90, thereby inhibiting its chaperone function and promoting the degradation of its client proteins, many of which are oncogenic signaling proteins involved in tumor cell proliferation and survival. This may lead to an inhibition of tumor cell proliferation. Hsp90, a chaperone protein upregulated in a variety of tumor cells, regulates the folding, stabilization and degradation of many oncogenic signaling proteins. Check for active clinical trials using this agent. (NCI Thesaurus)
