MedKoo product information:




Description of CPI-613: CPI-613  is a racemic mixture of the enantiomers of a synthetic alpha-lipoic lipoic acid analogue with potential chemopreventive and antineoplastic activities. Although the exact mechanism of action is unknown, alpha-lipoic acid analogue CPI-613 has been shown to inhibit metabolic and regulatory processes required for cell growth in solid tumors. Both enantiomers in the racemic mixture exhibit antineoplastic activity. The mechanism-of-action of CPI-613 appears distinct from the current classes of anti-cancer agents used in the clinic. CPI-613 demonstrates both in vitro and in vivo anti-tumor activity. CPI-613 was known to strongly disrupt tumor mitochondrial metabolism. CPI-613 disruption of tumor mitochondrial metabolism is followed by efficient commitment to cell death by multiple, apparently redundant pathways, including apoptosis, in all tested cancer cell lines. Further, CPI-613 shows strong antitumor activity in vivo against human non-small cell lung and pancreatic cancers in xenograft models with low side-effect toxicity. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Information about this agent

CPI-613, currently developed by Cornerstone Pharmaceuticals,  is the lead candidate from a new chemical class that, through a novel mechanism of action, targets metabolic changes considered to be common to many, if not all, cancer types. CPI-613 is currently being evaluated in several ongoing Phase I/II trials. CPI-613 was granted orphan drug status by the US FDA for pancreatic cancer, which has a poor prognosis, spreads rapidly and often goes undetected in its early stages.


Accoring to  Cornerstone Pharmaceuticals's website, in November of 2009, CPI-613 was named one of the “top most interesting oncology projects available for partnering” by Windhover Information, a leading provider of healthcare industry analysis.  CPI-613's key features found in preclinical tests include (1) active across a broad spectrum of cancer types (solid tumor and hematologic); (2) induces cancer cell death in animal models of human cancers with no toxic effect on normal cells at therapeutic levels; (3) demonstrates 100% efficacy against every human cancer type tested in cell culture.
