  • Darovasertib and Crizotinib combination observed manageable safety profile and clinical efficacy that appears superior to current standard of care in MUM
  • Clinical data update, will include confirmed ORR by RECIST 1.1 by HLA-A2 status, median progression free survival, HLA-A2(+) and (-) status prevalence across darovasertib clinical trials, and ctDNA molecular response rate
  • Press release summarizing the top-line results will be available on Monday, October 23, 2023, at approximately 6:00 am ET

SOUTH SAN FRANCISCO, Calif., Oct. 17, 2023 /PRNewswire/ -- IDEAYA Biosciences, Inc. (Nasdaq:IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, announces the publication of the abstract for a proffered paper session at the European Society of Medical Oncology Congress 2023 (ESMO 2023) relating to selected clinical data from the company's ongoing Phase 2 clinical trial evaluating darovasertib in combination with crizotinib in patients having metastatic uveal melanoma (MUM).   

Dr. Meredith McKean, M.D., MPH, Director, Melanoma and Skin Cancer Research at Sarah Cannon Research Institute, who is a clinical investigator on the Phase 2 clinical trial, will present the clinical data as summarized in the abstract, as follows:

  • Session No. 1081O
  • Title: ctDNA reduction and clinical efficacy of the darovasertib + crizotinib (Daro + Crizo) combination in metastatic uveal melanoma (MUM)
  • Date: Monday, October 23, 2023 at 8:50-9:00 am CEST
  • Dr. Meredith McKean, M.D., MPH, Sarah Cannon Research Institute (Nashville, TN, U.S.A)

In summary, the Phase 2 evaluation of the darovasertib and crizotinib combination in first-line and pretreated MUM patients showed a manageable safety profile and demonstrated clinical efficacy that appears superior to current standards of care. Human leukocyte antigen (HLA)-A*02:01 (HLA-A2) status was determined in a subset of patients enrolled in the company's clinical trials evaluating darovasertib. Clinical efficacy was observed in both HLA-A2 positive (HLA-A2(+)) and HLA-A2 negative (HLA-A2(-)) patients. ctDNA was reduced in almost all patients and ctDNA molecular responses were deep and sustained in the majority of patients. 

The reported data support IDEAYA's ongoing registrational Phase 2/3 study for potential accelerated approval of darovasertib and crizotinib for treatment of first-line HLA-A2(-) MUM patients, where there are no FDA approved therapies.

A press release summarizing the top-line results will be available on Monday, October 23, 2023, at approximately 6:00 am ET, and will be available on the Company's website, at its Investor Relations portal (
