About IDEAYA Biosciences:

IDEAYA Biosciences (NASDAQ: IDYA) is a public, clinical-stage oncology-focused precision medicine company committed to the discovery and development of targeted therapeutics for patient populations selected using DNA sequencing and other molecular diagnostics. Our approach integrates extensive capabilities in identifying and validating translational biomarkers with small molecule drug discovery to select patient populations most likely to benefit from the therapies we are developing. We are applying these capabilities across multiple classes of precision medicine, including direct targeting of oncogenic pathways and synthetic lethality – which represents an emerging class of precision medicine targets. We believe this diversified approach will enable us to deliver the right medicine to the right patient to drive a more robust clinical response.

IDEAYA recently announced a landmark strategic partnership with GSK in Synthetic Lethality for certain pipeline programs. The GSK partnership is transformative and enables IDEAYA and GSK to collectively build an industry leading platform and pipeline in Synthetic Lethality. For more information, please see
