Dracen Pharmaceuticals announces two presentations at the American Association for Cancer Research (AACR) Annual Meeting 2022


Dracen Pharmaceuticals Inc., a clinical stage biotech company developing anti-cancer drugs that target immuno-metabolism, announced today an oral and a poster presentation on its lead compound sirpiglenastat (DRP-104, which is currently in phase I/IIa clinical development) are to be presented at the American Association for Cancer Research (AACR) Annual Meeting 2022. The meeting is taking place between April 8-13, 2022, in New Orleans, Louisiana and virtually.

“Sirpiglenastat has a novel mechanism of action, including direct, broad inhibition of multiple glutamine dependent pathways in tumors as well as immuno-oncology activities affecting both adaptive and innate immune cells,” said Robert Wild, Ph.D., chief scientific officer, Dracen Pharmaceuticals. “We believe this unique profile has the potential to translate into profound impact on multiple tumors and across different types of cancers. Our preclinical data presented at AACR this year support this concept in high unmet medical need tumor types such as KRAS mutant non-small cell lung cancer co-harboring mutations in KEAP1 as well as PTEN/PIK3CA mutant head and neck squamous cell carcinoma. We are excited to continue the clinical development of sirpiglenastat in these indications.”

About DRP-104

Our lead glutamine antagonist, DRP-104 (sirpiglenastat), is currently in phase I/IIa clinical development. The mechanisms of action for DRP-104 include: a) direct inhibition of tumor cell addiction to glutamine metabolism leading to substantial single agent activity and tumor regression in multiple pre-clinical models; b) broad metabolic remodeling of the tumor microenvironment leading to enhanced anti-tumor immune activity; and c) stimulation of T effector, NK and NKT cells and inhibition of immunosuppressive MDSC and macrophage cells, potentially leading to greater long-term durable responses and survival.
