IDEAYA Biosciences Announces IND Submission for IDE574

IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a leading precision medicine oncology company, announced the submission of an investigational new drug (IND) application to the U.S. Food and Drug Administration (FDA) for IDE574, a potential first-in-class KAT6/7 dual inhibitor with high selectivity over related KAT5/8 enzymes. The company is targeting to begin a Phase 1 dose escalation trial of monotherapy IDE574 in the first quarter of 2026.

"IDE574 is a promising potential first-in-class molecule that potently inhibits two tumor-promoting epigenetic modulators, KAT6 and KAT7, while sparing other structurally similar KAT family members. Preclinical studies demonstrate KAT6 and KAT7 collaboratively control lineage-specific tumorigenic transcription factor activity essential for tumor cell proliferation and survival. Dual KAT6/7 inhibition by IDE574 disrupts tumor lineage identity and delivers robust anti-tumor activity in patient-derived lung and breast cancer xenograft models dependent upon lineage-specific transcription factor activity," said Michael White, Ph.D., Chief Scientific Officer of IDEAYA Biosciences.

IDE574 is an equipotent, highly selective, small molecule dual inhibitor of the lysine acetyltransferase (KAT) 6 and 7, both of which have been shown to support cancer cell survival. IND-enabling studies support the potential clinical evaluation of IDE574 monotherapy in patients with hormone receptor-positive breast cancer, lung adenocarcinoma as well as additional opportunities associated with lineage addiction. IDEAYA is targeting to share data from its preclinical work with IDE574 at a medical conference in the first half of 2026.
