First-Patient-In for Ph 1 Trial of IDE574 in Solid Tumor Indications, including Breast, Prostate, CRC, and Lung Cancer

“Targeting mechanisms of resistance and tumor heterogeneity in cancer are core strategies of our R&D efforts, and we are excited to advance IDE574 in the clinic to evaluate its potential as a monotherapy agent to drive deeper, more durable antitumor responses for patients versus historical clinical data published with KAT6-selective agents,” said Michael White, Ph.D., Chief Scientific Officer of IDEAYA Biosciences. “We are thrilled to advance another potential first-in-class agent into the clinic that targets large solid tumor indications of high unmet need, including breast, prostate, CRC, and lung cancer.  We believe the novel chromatin remodeling mechanism of the KAT6/7 dual inhibitor IDE574, has the potential for monotherapy efficacy and to treat breast cancer patient’s refractory to hormone-based therapy due to ESR1 mutations, and to evaluate rational combinations with assets in the IDEAYA pipeline,” said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.
