Cirius Therapeutics' Preclinical Data Demonstrates Potential for Lead Drug Candidate MSDC-0602K in NASH

Cirius Therapeutics' Preclinical Data Demonstrates Potential for Lead Drug Candidate MSDC-0602K in NASH 

SAN DIEGO, CA and KALAMAZOO, MI, USA I April 12, 2018 I Cirius Therapeutics announced today that it presented a late-breaking poster describing the activity of the company's lead drug MSDC-0602K in a three-dimensional bioprinted human tissue model of NASH at The International Liver Congress™ – occurring in Paris, France from April 11-15, 2018.

The poster, entitled "A human in vitro three-dimensional bioprinted tissue system can be used to model nutritional damage and protective effects of MSDC-0602K, a novel modulator of the mitochondrial pyruvate carrier" presented work performed using Organovo's (NASDAQ: ONVO) 3D bioprinted human liver tissue and was presented by Dr. Jerry Colca from Cirius Therapeutics.

The research demonstrated that adding fructose (sugar) and fatty acids to three-dimensional bioprinted human liver tissue produced NASH-type liver pathology, including steatosis, inflammation, ballooning and fibrosis. Addition of MSDC-0602K to the tissue showed evidence of reduced disease progression, including reductions in collagen deposition and stellate cell activation, in the liver model.

"The data shown in this human liver model demonstrates conclusively that oversupply of nutrients leads directly to NASH-like pathology, including fibrosis," said Dr. Colca. "In addition, we see in this 3-D tissue model evidence that treatment with MSDC-0602K, which modulates metabolism by slowing the transport of the important metabolic intermediate pyruvate into the mitochondria, reduces signs of NASH. This supports our thesis that restoring nutritional balance on a cellular level has potential to treat NASH."

This work follows recently published work demonstrating that attenuation of pyruvate metabolism with MSDC-0602K via modulation of the mitochondrial pyruvate carrier (MPC) can both prevent and reverse liver fibrosis.

"The ability to model human liver disease and drug intervention with our technology is a powerful tool for helping companies such as Cirius evaluate their drug candidates for the treatment of NASH," Paul Gallant, general manager, Organovo. "As the results of this research show, it can also yield valuable insights about potential biomarkers that can be monitored during liver disease progression."
