- Trial Initiation: IDEAYA Biosciences has enrolled its first patient in a Phase 1 dose escalation trial to evaluate the safety and efficacy of IDE574, a potential first-in-class oral small molecule dual inhibitor of KAT6/7, aimed at providing new treatment options for patients with various solid tumors, including breast and prostate cancer.
- Selectivity Advantage: IDE574 demonstrates single-digit to low-teen nanomolar potency in target engagement assays against KAT6 and KAT7, with a selectivity of approximately 350 to 2,000-fold over KAT5 and KAT8, which minimizes impact on normal cellular functions, enhancing its therapeutic profile.
- Significant Antitumor Activity: In preclinical models, IDE574 exhibits robust and durable monotherapy antitumor activity superior to KAT6 inhibition alone, particularly in tumors with 8p11 amplifications and ESR1 mutations, highlighting its potential to address resistance mechanisms in cancer treatment.
- Future Development Outlook: IDEAYA plans to present the potential first-in-class and best-in-class preclinical profile of IDE574 at the AACR 2026 conference, underscoring its strategic significance in addressing high unmet needs in solid tumors, particularly for breast cancer patients resistant to hormone-based therapies.
