Selected Pipeline Developments and Corporate Updates
Darovasertib for Uveal Melanoma
- IDEAYA presented complete data from the primary analysis of OptimUM-02 in a late-breaking oral presentation at the 2026 American Society of Clinical Oncology (ASCO) meeting in
Chicago , Illinois. Data were from a total of 313 patients with first line (1L) HLA*A2:01-negative mUM as of a January 23, 2026 cutoff date, randomized 2:1 to darovasertib in combination with crizotinib (the darovasertib combination) or an investigator's choice of therapy (ICT) arm reflective of real-world clinical practice that included ipilimumab plus nivolumab (anti-CTLA-4/PD-1) or pembrolizumab (anti-PD-1). The primary endpoint is median progression-free survival (PFS) as assessed by blinded independent central review (BICR). Secondary endpoints include safety and investigator assessed PFS, overall response rate (ORR), disease control rate (DCR) and duration of response.- The trial met its primary endpoint, with patients receiving the darovasertib combination demonstrating a statistically significant improvement in median PFS of 6.9 months versus 3.1 months in the ICT arm by BICR (HR: 0.42;
95% CI: 0.30, 0.59; p-value: <0.0001). A similar result was observed based on investigator assessment, with the combination leading to a median PFS of 6.7 months versus 2.7 months in the ICT arm (HR: 0.36;95% CI: 0.26, 0.50, p-value: <0.0001). - Patients receiving the darovasertib combination also had clinically meaningful and statistically significant improvements across all key secondary endpoints.
- Overall survival (OS) data was still immature as of the January 23, 2026 cutoff date; however, there was an early trend in OS improvement in the darovasertib combination arm relative to the ICT arm. IDEAYA plans to provide an update on the OS data as part of the pre-specified interim analysis expected in mid-2027.
- Overall, the darovasertib combination was generally well-tolerated with a manageable safety profile, consistent with previous results and known side-effects of each agent.
- The trial met its primary endpoint, with patients receiving the darovasertib combination demonstrating a statistically significant improvement in median PFS of 6.9 months versus 3.1 months in the ICT arm by BICR (HR: 0.42;
- IDEAYA has completed enrollment of approximately 100 HLA*A2:01-positive mUM patients in the single-arm, Phase 2 OptimUM-01 trial of the darovasertib combination. The company plans to present updated ORR, PFS and OS results from approximately 85 efficacy-evaluable HLA*A2:01-positive patients, including both first line and pre-treated patients, at the 2026 European Society of Medical Oncology (ESMO) Congress taking place in October in
Madrid, Spain .- Data from OptimUM-01 will be included as part of IDEAYA's NDA submission to the
U.S . Food and Drug Administration (FDA) to support regulatory discussions that have the potential to expand the labeled indication of the darovasertib combination. IDEAYA also plans to publish data from OptimUM-01 for potential inclusion in the clinical practice guidelines to support the use of the combination in certain HLA*A2:01-positive mUM patients. Inclusion in the clinical practice guidelines, if achieved, is intended to provide healthcare professionals with an evidence-based rationale to consider use of darovasertib in appropriate patients and may support payer coverage for such patients.
- Data from OptimUM-01 will be included as part of IDEAYA's NDA submission to the
- Updated clinical data will also be presented at ESMO from the ongoing Phase 2 OptimUM-09 trial of neoadjuvant darovasertib. Based on ongoing patient recruitment considerations for the global Phase 3 OptimUM-10 trial IDEAYA is assessing optimal capital allocation across its portfolio, including accelerating its investment into other high-value programs, such as the DLL3 registrational trial and MTAP/KRAS combination studies. As part of this assessment, the Company is evaluating whether published data from the OptimUM-09 trial could provide a pathway for inclusion in clinical practice guidelines, supporting the use and payer coverage of darovasertib in the neoadjuvant setting of primary uveal melanoma.
- If successful, this approach has the potential to accelerate patient access while reducing the investment required to support clinical utility in the neoadjuvant setting, enabling increased focus on other strategic development priorities.
- Following the successful completion of a Type C meeting with the FDA earlier this year, IDEAYA and its partner, Les Laboratoires Servier (Servier), initiated a global Phase 3 registrational trial (OptimUM-11) to evaluate the darovasertib combination in the adjuvant setting of primary uveal melanoma. OptimUM-11 will enroll approximately 450 patients with increased risk of metastasis, irrespective of HLA status, randomized 1:1 to 12-months of treatment with the combination or observation. The primary endpoint of the trial is relapse-free survival.
ADC / DDR combinations
- IDE849 (DLL3 TOP1 ADC): IDEAYA's partner in
China , Jiangsu Hengrui Pharmaceuticals (Hengrui), plans to provide a clinical data update from their ongoing Phase 1 trial in SCLC and NEC at ESMO. The update will include updated ORR, PFS and safety data along with 12-month landmark OS data from approximately 100 patients enrolled in the trial. IDEAYA also plans to provide the first clinical data from its ongoing global Phase 1/2 trial of IDE849 in SCLC and NEC in the second half of 2026.- IDEAYA is having discussions with the FDA to align on the design of a Phase 3 registrational trial of IDE849 in refractory SCLC and/or NEC and plans to provide more detail on the proposed trial design with its data update in the second half of the year, with the goal of initiating the registrational trial by the end of 2026. Hengrui is also targeting to initiate a Phase 3 registrational trial for IDE849 in refractory SCLC in
China by the end of 2026.

Hengrui is also targeting to initiate a Phase 3 registrational trial for IDE849 in refractory SCLC in
- IDE161 (PARG): IDEAYA is also conducting a Phase 1 combination trial of IDE849 with IDE161, a potential first-in-class poly(ADP-ribose) glycohydrolase (PARG) inhibitor in patients with DLL3-upregulated solid tumors, including SCLC, NEC and melanoma. IDEAYA has previously shared preclinical data demonstrating the mechanism of action and potential synergy of IDE161 in combination with TOP1-payload based ADCs in driving enhanced anti-tumor activity.
- IDE034 (B7H3/PTK7 bispecific TOP1 ADC): IDEAYA plans to provide initial clinical data from its ongoing Phase 1 dose escalation trial by the end of 2026 or early 2027, which is expected to include preliminary safety and efficacy data. IDE034 is a potentially first-in-class B7H3/PTK7 bispecific TOP1 ADC designed to be internalized only when its target antigens are co-expressed on the same tumor cell, which may enhance its selectivity and tolerability profile relative to monovalent antibody formats.
MTAP pathway
- IDE892 (PRMT5): monotherapy expansion has been initiated in the Phase 1/2 clinical trial evaluating IDE892 in MTAP-deleted solid tumors, with a focus on non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC). The expansion has been initiated at projected efficacious target human exposures where 24-hour target EC90 coverage has been achieved. The IDE892 maximum tolerated dose (MTD) has not yet been reached in the ongoing dose escalation.
- IDE397 (MAT2A): a Phase 1/2 combination cohort was initiated to evaluate IDE892 with IDE397, IDEAYA's proprietary MAT2A inhibitor, in MTAP-deleted cancers. Expansion is planned by year end 2026 or early 2027, with an initial clinical focus on MTAP-deleted NSCLC. Dual inhibition of MAT2A and PRMT5 has demonstrated durable and well-tolerated tumor regressions in preclinical MTAP-deleted tumor models, including in NSCLC.
- In May, IDEAYA entered into a clinical trial collaboration with Roche to explore IDE892 in combination with RG6505, Roche's proprietary Phase 1 pan-RAS inhibitor, in MTAP-deleted, RAS-mutant PDAC to target the genetic co-alterations of MTAP and KRAS in this indication. IDEAYA plans to begin a Phase 1 combination trial in the second half of 2026.
- Upon joint IDEAYA and Roche approval, the collaboration may also evaluate a combination triplet with IDE892, RG6505, and IDE397, IDEAYA's proprietary Phase 1/2 MAT2A inhibitor.
KAT6/7
- IDE574 (KAT6/7): a Phase 1 dose escalation trial is underway in solid tumors including breast, prostate, colorectal and lung cancer. IDE574 is a selective, equipotent dual inhibitor of both KAT6 and KAT7 which spares other structurally similar paralogs, including KAT5 and KAT8, which are required for normal cell function. KAT6 and KAT7 are epigenetic modulators of cell identity and lineage commitment programs that are corrupted by oncogenic transformation.
