"This quarter we continued to execute on our strategic vision to build a leading precision medicine oncology company, with the broad advancement of 4 potential first-in-class clinical programs across multiple patient selection biomarker populations, including GNAQ/11, MTAP-deletion, and HRD solid tumors. Next, through our excellence in translational research, we have discovered and enabled what we believe are potential first-in-class rational combinations across our diverse clinical pipeline, including with Pfizer, Amgen, Gilead, GSK, and Merck. IDEAYA's next generation programs have also made tremendous progress this past quarter, including the Werner Helicase program that is on-track for an IND-filing this year and our second MTAP-deletion program where we anticipate a development candidate in 2024 to enable a potential wholly-owned clinical combination with IDE397," said
"We are excited to provide a clinical data update from the ongoing investigator-sponsored Phase 2 neoadjuvant uveal melanoma trial as an oral presentation at ASCO 2024. In addition, we are targeting to provide a clinical data update from our company-sponsored Phase 2 neoadjuvant UM trial and receive FDA regulatory guidance for a potential registrational path in the neoadjuvant uveal melanoma indication in the second half of 2024. In addition, our potential first-in-class clinical pipeline including programs in Phase 1/2 such as the MAT2A inhibitor IDE397 which targets MTAP-deleted solid tumors and PARG inhibitor IDE161 which targets HRD solid tumors, both continue to make important advancements. For IDE397, we have selected a move-forward Phase 2 monotherapy expansion dose in MTAP-deletion squamous non-small cell lung cancer. For the IDE161 program, we are targeting to initiate the Phase 2 monotherapy expansion in HRD solid tumors in the second half of 2024," added

IDE161 Program in Tumors with Homologous Recombination Deficiency
IDE161 is a potential first-in-class inhibitor of poly(ADP-ribose) glycohydrolase (PARG), a novel, mechanistically distinct target in the same clinically validated biological pathway as poly(ADP-ribose) polymerase (PARP). IDE161 received two FDA Fast Track designations in platinum-resistant advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 mutations, and in pretreated advanced or metastatic HR+, Her2-, BRACA1/2 mutant breast cancer. IDE161 is currently being evaluated in IDE161-001 (NCT05787587), a Phase 1/2 trial of IDE161 in solid tumors with HRD.
Early clinical data from the dose escalation cohorts were reported and the Phase 1 dose optimization portion of the trial is ongoing with the goal to select an initial Phase 2 expansion dose. Solid tumor types of focus, include ER+ HER-breast, colorectal, endometrial, and prostate cancers. Selection of an initial Phase 2 monotherapy expansion dose in HRD solid tumors is targeted in the second half of 2024. The Company is currently validating IDE161 combination opportunities preclinically and targeting identification of additional combination(s) in 2024.
