"We are looking forward to the first public presentation of our orally-active series of covalent inhibitors of KRAS G12C. We will describe the identification of novel lead matter and the structure-based approach that led to increases in potency. Further, we will present in vivo data for an early lead molecule that resulted in regressions in a xenograft tumor model. These results led us to our lead candidate, MRTX849, that has a planned IND (investigational new drug) filing in Q4 2018," said Matt Marx, Ph.D., Vice President of Drug Discovery.

Details for the poster presentation are listed below.

Poster Title: Structure-based drug discovery of a selective, covalent KRAS G12C inhibitor with oral activity in animal models of cancer
Poster Number: MEDI 144
Date and Time: Sunday, August 197:00 PM
