IDEAYA Biosciences has submitted an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for the initiation of a Phase 1 clinical trial to evaluate IDE397, a small molecule methionine adenosyltransferase 2a (MAT2A) inhibitor, for the treatment of patients having solid tumors with methylthioadenosine phosphorylase (MTAP) deletion.

"The IDE397 IND submission is an important milestone for IDEAYA as we advance our broader synthetic lethality pipeline of potential first-in-class therapies. IDE397 was discovered through our efforts to develop a potential best-in-class MAT2A inhibitor, and we have achieved our target product profile," said Michael Dillon, Ph.D., Chief Scientific Officer, IDEAYA Biosciences. "IDE397 is highly selective and active in the MTAP-deletion setting, which represents approximately 15% of all solid tumors, and we are excited about the potential impact IDE397 can make for these patients," said Yujiro S. Hata, Chief Executive Officer, IDEAYA Biosciences.
