IDEAYA Biosciences Announces IDE892, a Potential Best-in-Class MTA-Cooperative PRMT5 Inhibitor, Initiates a Phase 1/2 Clinical Combination Study in MTAP-Deleted Pancreatic and Lung CancersJune 15, 2026 6:00 AM
PR Newswire (US) IDE892 is a potential best-in-class MTA-Cooperative PRMT5 combination partner with MAT2A and pan-RAS inhibitors, with favorable drug-like propertiesIDE892 has a CYP3A4 IC50 greater than 45 micromolar, and did not show time dependent inhibition of any of the 7 major cytochrome P450s (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4) based on full kinetic CYP inactivation assaysIDE892 monotherapy Phase 1 escalation has cleared multiple dose cohorts with maximally efficacious target exposures anticipated at a favorable pill size and the MTD has not yet been reached. IDE892 monotherapy expansion is anticipated in Q3 2026MTAP-deletion is estimated to occur in up to 40% of pancreatic cancer and ~15% of non-small cell lung cancer (NSCLC)SOUTH SAN FRANCISCO, Calif., June 15, 2026 /PRNewswire/ -- IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a leading precision medicine oncology company, today announced that the first patient has been enrolled in its Phase 1 clinical trial evaluating IDE892, a potential best-in-class methylthioadenosine (MTA)-cooperative inhibitor of PRMT5, in combination with IDE397, a potential first-in-class and best-in-class inhibitor of MAT2A, in MTAP-deleted solid tumors, with a focus on NSCLC and pancreatic cancer. In preclinical studies, dual inhibition of PRMT5 and MAT2A with the combination of IDE892 and IDE397 resulted in potent anti-tumor activity in MTAP-deleted tumor models, including complete and durable responses at well-tolerated doses below those required for monotherapy activity. "We are excited to begin enrolling this Phase 1 combination trial evaluating IDE892 in MTAP-deleted pancreatic cancer and non-small cell lung cancer. We designed IDE892 with potential best-in-class properties, including approximately 1,400-fold selective MTA-PRMT5 cooperative binding versus SAM-PRMT5 cooperative binding intended to maximize its therapeutic window and favorable drug-like properties to enable rational combinations with IDE397 and pan-RAS inhibitors. This trial exemplifies our clinical development strategy of enabling rational combinations to deliver deeper and more durable responses for MTAP-deleted pancreatic cancer and lung cancer patients where there are currently no approved treatment options," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.Loss of MTAP leads to the accumulation of MTA and increased dependence on PRMT5 and MAT2A, two key enzymes involved in methylation and RNA splicing. In MTAP-deleted tumors, this biology establishes a robust synthetic lethal vulnerability that underpins the mechanistic rationale for combining IDE892 and IDE397. IDEAYA also entered into a clinical collaboration with Roche evaluating IDE892 in combination with RG6505, Roche's Phase 1 pan-RAS inhibitor, in MTAP-deleted pancreatic ductal adenocarcinoma (PDAC) to target the genetic co-alterations of MTAP and KRAS in this indication. Next, IDEAYA is advancing a third proprietary program for MTAP-deleted solid tumors targeting CDKN2A, the most common co-alteration of MTAP, through ongoing preclinical toxicology studies to support an investigational new drug (IND) application in the first half of 2027.MTAP deletion is estimated to occur in approximately 15% of all solid tumors, including 15-20% of NSCLC and up to 40% of pancreatic cancer. There are no approved therapies for MTAP-deleted cancers, highlighting the significant unmet need and opportunity for new precision therapies for these patients.About IDEAYA BiosciencesIDEAYA is a precision medicine oncology company committed to the discovery, development, and commercialization of transformative therapies for cancer. Our approach integrates expertise in small-molecule drug discovery, structural biology and bioinformatics with robust internal capabilities in identifying and validating translational biomarkers to develop tailored, potentially first-in-class targeted therapies aligned to the genetic drivers of disease.

B7-H3 Becomes The Hottest Antigen In Oncology, And One NK Engager Enters ClinicMay 18, 2026 2:22 PM
PR Newswire (US) Issued on behalf of GT Biopharma, Inc. SAN FRANCISCO, May 18, 2026 /PRNewswire/ -- USA News Group News Commentary — For more than two decades, B7-H3 sat on the shortlist of theoretically perfect cancer drug targets that nobody could quite figure out how to hit. The protein is broadly overexpressed across some of the most common — and most lethal — solid tumors, including prostate, lung, breast, ovarian, head and neck, and pancreatic cancers. It is largely absent from healthy tissue. It correlates with poor prognosis. On paper, it has every quality a drug developer wants. In practice, three B7-H3-targeting antibody-drug conjugates have entered the clinic, and none have yet been approved.[1] That is starting to change. Key Takeaways GT Biopharma (NASDAQ: GTBP) dosed the first patient on May 14, 2026 in a Phase 1 dose-escalation basket trial of GTB-5550, its B7-H3-targeted natural killer cell engager for solid tumors expressing B7-H3 — the third TriKE candidate to enter the clinic, and the first tested with patient-friendly subcutaneous dosing.FDA cleared the GTB-5550 IND in February 2026, with dose-escalation cohorts prioritizing advanced prostate, ovarian, and pancreatic cancer patients who have failed prior therapy. The Company targets a portion of the estimated US$362 billion global solid tumor market.B7-H3 has rapidly become one of the most actively pursued antigens in solid tumor oncology in 2026, with bispecific antibody-drug conjugates, systemic radiopharmaceuticals, and now natural killer cell engagers all converging on the same target — broadly overexpressed across prostate, lung, breast, ovarian, head and neck, and pancreatic cancers, largely absent from healthy tissue.GT Biopharma reported a cash balance as of March 31, 2026 of approximately US$9 million, anticipated to provide sufficient cash runway through Q4 2026, with Phase 1 updates anticipated in 2H 2026 as dose escalation progresses.In 2026, B7-H3 has become one of the most actively pursued antigens in solid tumor oncology. The mechanisms are widely varied — bispecific antibody-drug conjugates at IDEAYA, antibody-drug conjugates at GSK paired with bispecific antibody combinations at Summit Therapeutics, systemic radiopharmaceuticals across other pipelines, and now a natural killer cell engager from GT Biopharma, Inc. (NASDAQ: GTBP) — but the target is the same. The convergence is what makes the moment distinctive. When mechanism diversity collapses onto a single antigen, the antigen is what is being repriced.Read more on GT Biopharma by clicking here GTB-5550: The Third TriKE Into The Clinic, And The First Subcutaneous On May 14, 2026, GT Biopharma announced that the first patient had been dosed in a Phase 1 dose-escalation basket trial evaluating GTB-5550, its B7-H3-targeted natural killer cell engager for solid tumors expressing B7-H3.[2] GTB-5550 is the third TriKE — Tri-specific Killer Engager — molecule from GT Biopharma to enter the clinic. Critically, it is also the first to be tested with subcutaneous dosing, a design choice that distinguishes it from a category where most engager therapies have historically required continuous infusion.[1]"Dosing the first patient in our GTB-5550 Phase 1 trial is a pivotal milestone for GT Biopharma and represents the natural evolution of our TriKE platform into the broader opportunity of treating patients with a variety of solid tumors," said Michael Breen, Executive Chairman and Chief Executive Officer of GT Biopharma.[1] The May 15, 2026 Q1 financial results release confirmed the broader pipeline context: with the GTB-5550 Phase 1 trial now active, GT Biopharma has advanced three TriKE candidates into the clinic — a milestone Breen described as one that "underscores the continued momentum of our pipeline."[3]The molecular architecture of GTB-5550 reflects the design discipline GT Biopharma has built into its 2nd-generation TriKE platform. The molecule is a camelid (cam) anti-CD16 / WT IL-15 / cam anti-B7-H3 tri-specific natural killer cell engager — a single-chain recombinant TriKE comprised of three components joined by flexible linkers: a nanobody arm that engages the CD16 activating receptor on natural killer cells, a wildtype IL-15 linker arm to drive NK cell proliferation, priming, and survival, and a nanobody arm that specifically engages B7-H3 to target the antigen expressed on tumor cells.[4] The 2nd-generation TriKE platform that underlies GTB-5550 has been described as 10–40 times more potent than 1st-generation TriKE, and all current TriKE development at the Company is focused on the 2nd-generation platform.[4]Dose Escalation: Prostate, Ovarian, And Pancreatic Cancer Prioritized FDA cleared the GTB-5550 IND application in February 2026.[5] In the Company's commentary on the clearance, Breen described it as "a defining moment for GT Biopharma as we bring another NK cell engager into the clinic."[5] The Phase 1 trial is structured as a basket trial open to patients with common solid tumors that express B7-H3. In the dose-escalation component, enrollment is being prioritized for advanced prostate, ovarian, and pancreatic cancer patients who have failed prior therapy.[5] The clinical design reflects a deliberate choice: prioritize patient populations where the unmet need is highest, where B7-H3 expression is well-characterized, and where the regulatory pathway around accelerated approval has historically been most navigable.Phase 1 trial updates are anticipated in the second half of 2026 as enrollment progresses through dose escalation cohorts.[3] The Q1 2026 financial results release reported a cash balance as of March 31, 2026 of approximately US$9 million, anticipated to provide sufficient cash runway through Q4 2026.[3] The funding visibility, paired with the Phase 1 first-patient-dosed milestone, gives investors a defined catalyst window across the back half of 2026 for the first set of clinical readouts from the new program.The TriKE platform has been developed under an exclusive worldwide license agreement with the University of Minnesota, providing GT Biopharma with the rights to further develop and commercialize therapies using TriKE technology.[2] The Company's broader pipeline now spans GTB-3650 (the first 2nd-generation camelid nanobody TriKE, being tested clinically for CD33-positive leukemias including AML and MDS), GTB-5550 (the B7-H3 program for solid tumors), and GTB-7550 (in development for CD19-positive lymphoid malignancies and autoimmune disease).[4]Why The B7-H3 Convergence Matters The strategic case for GTB-5550 is sharpened by what is happening around B7-H3 across the rest of the oncology sector. The number of high-quality drug developers now actively pursuing the antigen, across multiple modalities, has shifted B7-H3 from "theoretically perfect" to "actively competitive" in less than 18 months. That competition matters less as a threat than as a validation. When IDEAYA is enrolling a bispecific B7-H3 / PTK7 antibody-drug conjugate, GSK is partnering its B7-H3 antibody-drug conjugate with Summit Therapeutics's ivonescimab in multiple solid tumor settings, and GT Biopharma is dosing the first patient in a B7-H3 NK cell engager Phase 1 trial — all within the first half of 2026 — the read-through is that the antigen has reached the threshold where the drug developer community has concluded the biology supports clinical translation.[1]What differentiates GT Biopharma inside that crowd is the mechanism. GTB-5550 is the only B7-H3-targeted natural killer cell engager in the Phase 1 patient-dosing window in 2026, and the only one tested with subcutaneous dosing. The TriKE design — engaging CD16 on NK cells, embedding an IL-15 moiety to drive NK cell proliferation and persistence, and targeting B7-H3 on tumor cells — gives the molecule a mechanistic profile that is structurally distinct from the antibody-drug conjugate and bispecific antibody approaches that dominate the rest of the B7-H3 development field.How GT Biopharma Sits Inside The B7-H3 And Solid Tumor Universe Summit Therapeutics Inc. (NASDAQ: SMMT) is one of the largest publicly traded oncology biotechs by market capitalization, with a market value around US$14 billion as of early 2026.[6] On January 12, 2026, Summit announced a clinical trial collaboration with GSK plc to evaluate ivonescimab — Summit's lead PD-1 / VEGF bispecific antibody — in combination with GSK's novel investigational B7-H3-targeting antibody-drug conjugate, risvutatug rezetecan (also known as GSK'227), across multiple solid tumor settings including small cell lung cancer.[7] Summit subsequently announced FDA acceptance of its Biologics License Application for ivonescimab on January 29, 2026, with a Prescription Drug User Fee Act goal action date of November 14, 2026.[8] Summit represents the institutional-scale comparable for the broader bispecific oncology investment thesis B7-H3 development is now inside.IDEAYA Biosciences, Inc. (NASDAQ: IDYA) announced in February 2026 that the first patient had been enrolled in its Phase 1 dose-escalation/expansion trial evaluating IDE034, a potential first-in-class PTK7 / B7-H3 bispecific TOP1 antibody-drug conjugate.[6] The design rationale is unusually specific: IDEAYA estimates that B7-H3 and PTK7 are co-expressed in approximately 30–40% of certain large solid tumor types — including lung, breast, ovarian, and colorectal cancers — while exhibiting minimal dual-antigen expression in normal tissue.[6] The drug is designed to be internalized only when both antigens are co-expressed on the same tumor cell, an architecture intended to enhance selectivity and tolerability compared to monovalent antibody formats.[6] IDEAYA offers the cleanest small-to-mid-cap B7-H3 development comparable in the public market.GSK plc (NYSE: GSK) is one of the largest pharmaceutical companies in the world by market cap, and the B7-H3-targeting antibody-drug conjugate risvutatug rezetecan (GSK'227) sits inside its broader oncology platform. The January 12, 2026 collaboration with Summit Therapeutics to combine GSK'227 with ivonescimab across multiple solid tumor settings, including small cell lung cancer, places GSK directly in the B7-H3 development conversation — and signals to the broader industry that one of the largest pharmaceutical companies in the world has concluded the B7-H3 modality is worth aggressive clinical investment.[7] GSK's involvement is a structural validation of the antigen that supports the broader investment thesis around B7-H3-targeted programs at every scale.Innate Pharma S.A. (NASDAQ: IPHA) has long been one of the more prominent publicly listed pure-play NK cell engager companies, with multispecific approaches that hit triggering receptors including NKp46 — adding to the broader CD16-anchored NK cell engagement framework. Innate's NK cell engager IPH6101 was advanced with Sanofi as a clinical-stage candidate for blood cancers. Innate provides a relevant comparable for the NK cell engager mechanism category specifically — distinct from the antibody-drug conjugate and bispecific antibody mechanisms that dominate most of the rest of the B7-H3 field — and helps frame the mechanism-specific investment thesis for an engager-platform company like GT Biopharma.Across all four comparables, the pattern is recognizable: 2026 is the year B7-H3 became one of the most-watched antigens in oncology, and the development pipelines now actively pursuing it span four different mechanism categories. GT Biopharma's distinction inside that crowd is that its TriKE platform is the only NK cell engager with a B7-H3 program currently dosing patients.The Catalyst Window Ahead The remainder of 2026 sets up a defined catalyst window for GT Biopharma. The Phase 1 dose-escalation trial for GTB-5550 is now enrolling, with the first patient dosed on May 14, 2026, and updates anticipated in 2H 2026 as the trial progresses through dose escalation cohorts.[3] The Company's cash position of approximately US$9 million as of March 31, 2026 is expected to provide sufficient runway through Q4 2026 — meaning the question of when initial efficacy or safety signals can be expected, and when additional capital may need to be raised against initial Phase 1 read, are both visible inside the next two to three quarters.[3]For investors who have read the B7-H3 convergence — and concluded that the antigen has reached the validation threshold where mechanism differentiation now matters — GT Biopharma offers a small-cap, single-platform exposure to the only NK cell engager program currently in B7-H3 patient dosing. Whether the Phase 1 data ultimately supports translation into a registrational program will be tested cohort by cohort across the back half of 2026 and into 2027. The window for new entrants into the B7-H3 antigen-targeted clinical field is no longer wide open — but the window for differentiated mechanisms inside it has, briefly, never been more visible.CONTACT:USA News Group

IH Market News
IDEAYA Biosciences (NASDAQ:IDYA) stock surged 27% on Monday after the company reported encouraging topline results from its Phase 2/3 registrational study evaluating darovasertib in combination with crizotinib for first-line treatment of metastatic uveal melanoma.The OptimUM-02 study achieved its primary endpoint, demonstrating a statistically significant improvement in median progression-free survival (PFS). Patients receiving the combination therapy recorded a median PFS of 6.9 months, compared with 3.1 months for those given investigator-selected treatments, corresponding to a hazard ratio of 0.42 (95% CI: 0.30–0.59).A total of 313 patients with HLA-A02:01-negative metastatic uveal melanoma were enrolled in the trial. Of these, 210 patients were treated with the darovasertib combination, while 103 were assigned to the control arm, where 76% received ipilimumab plus nivolumab and 24% were treated with pembrolizumab.The secondary endpoint of overall response rate also favored the combination therapy, reaching 37.1% versus 5.8% for standard treatment options. The regimen reduced the risk of disease progression by 58%, based on blinded independent central review.While overall survival data remains immature, the company noted an early signal of improvement in the combination arm. The therapy was generally well tolerated, with a manageable safety profile. The most frequently reported Grade 3 or higher adverse events included diarrhea, syncope and hypotension.IDEAYA said it intends to file a New Drug Application with the U.S. Food and Drug Administration in the second half of 2026, seeking accelerated approval. Full results from the OptimUM-02 trial are expected to be presented at a major medical conference later in 2026.The study was carried out in partnership with Servier, an international pharmaceutical group.

PR Newswire (US)

Potential first-in-class and selective equipotent dual inhibitor of KAT6/7 with single-digit to low teens nano-molar cellular potency in target engagement assays against KAT6 and KAT7, and ~350-to-2,000-fold selectivity over the KAT5 and KAT8 paralogsKAT6/7 dual inhibitor demonstrates greater monotherapy efficacy and durability than KAT6 selective inhibitors in preclinical CDX and PDX modelsMultiple combination opportunities with IDE574 and IDEAYA's proprietary pipelinePotential first-in-class and best-in-class preclinical profile will be presented at AACR 2026SOUTH SAN FRANCISCO, Calif., April 6, 2026 /PRNewswire/ -- IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a leading precision medicine oncology company, today announced that the first patient has been enrolled in its Phase 1 dose escalation trial evaluating IDE574, a potential first-in-class oral small molecule equipotent dual inhibitor of the lysine acetyltransferase (KAT) 6 and 7 paralogs, both of which have been shown to support cancer cell survival.  The company is planning to evaluate safety, efficacy and pharmacokinetics of IDE574 as a monotherapy in the Phase 1 dose escalation trial in solid tumor patients, including breast, prostate, colorectal, 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.IDE574 is a selective, equipotent dual inhibitor of both KAT6 and KAT7 with single-digit to low-teen nanomolar cellular potency in target engagement assays, which spares other structurally similar KAT paralogs with approximately a 350-to-2,000-fold selectivity windows versus KAT5 and KAT8, both of 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.  Estrogen-receptor 1 mutations (ESR1) is a common acquired resistance mechanism to endocrine based therapy in breast cancer with prevalence from 10 to 50% (Fuqua, et al., Cancer, July 2019; Zundelevich, et al., Breast Cancer Research, February 2020) highlighting the unmet need for alternative drug mechanisms, such as KAT6/7.  IDE574 has shown robust and durable monotherapy anti-tumor activity, superior to KAT6 inhibition alone, in preclinical tumor models with 8p11 amplifications and ESR1 mutations, as well as in selected indications dependent upon lineage-specific transcription factor activity.About IDEAYA BiosciencesIDEAYA is a precision medicine oncology company committed to the discovery, development, and commercialization of transformative therapies for cancer.  Our approach integrates expertise in small-molecule drug discovery, structural biology and bioinformatics with robust internal capabilities in identifying and validating translational biomarkers to develop tailored, potentially first-in-class targeted therapies aligned to the genetic drivers of disease.  We have built a deep pipeline of product candidates focused on synthetic lethality and antibody-drug conjugates, or ADCs, for molecularly defined solid tumor indications.  Our mission is to bring forth the next wave of precision oncology therapies that are more selective, more effective, and deeply personalized with the goal of altering the course of disease and improving clinical outcomes for patients with cancer.Forward-Looking Statements This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements regarding the potential therapeutic benefits, safety, tolerability, efficacy, pharmacokinetics and clinical development of IDE574; the potential of IDE574 as a first-in-class or best-in-class therapy; the expected design, timing, and results of the Company's Phase 1 clinical trial; the potential for IDE574 to demonstrate monotherapy activity or durability of response; the potential to address resistance mechanisms, including ESR1 mutations; the applicability of IDE574 across multiple solid tumor indications; and the potential for combination strategies with IDEAYA's pipeline.  Such forward-looking statements are based on management's current expectations, assumptions and beliefs and involve substantial risks and uncertainties that could cause actual results, including, but not limited to, those related to IDEAYA's clinical programs, commercial activities, and performance and/or achievements, to differ significantly and/or materially from those expressed or implied by the forward-looking statements.  Such risks and uncertainties include, among others, the uncertainties inherent in the drug development process, including the process of designing and conducting preclinical and clinical trials, enrollment rates, safety outcomes, efficacy results, regulatory interactions and decisions, and the ability to translate preclinical findings into clinical benefit, manufacturing and supply risks, competition, changes in standard of care, the timing and success of commercialization efforts, the outcome of collaborations and licensing arrangements, IDEAYA's ability to successfully establish, protect and defend its intellectual property, and other matters that could affect the sufficiency of financial resources to fund operations.

(NASDAQ: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced first-patient-in for a Phase 1 clinical trial combination study to evaluate IDE849, a potential first-in-class delta-like ligand 3 (DLL3)-targeting Topo-I-payload antibody drug conjugate (ADC) program, and IDE161, a potential first-in-class poly(ADP-ribose) glycohydrolase (PARG) inhibitor. The Phase 1 combination study will be evaluated in DLL3 upregulated solid tumor indications, including small cell lung cancer (SCLC), neuroendocrine tumors (NETs), neuroendocrine carcinomas (NECs), and melanoma.







"We are excited about the progress in our Phase 1 IDE849 monotherapy study to determine the RP2D and to initiate a registrational study by year-end, and the advancement of our wholly owned first-in-class clinical combination of IDE849 and IDE161 in DLL3 upregulated solid tumor indications," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences. "We are leveraging our deep scientific expertise in DNA damage repair to enable this rational combination with IDE161, with the goal of inducing accumulation of TOP1 lesions to enhance the clinical efficacy and durability of our proprietary TOP1-payload ADCs, including IDE849 and IDE034, a Phase 1 B7H3/PTK7 bispecific TOP1 ADC," said Michael White, Ph.D., Chief Scientific Officer, IDEAYA Biosciences.IDEAYA is advancing a multi-site global Phase 1 clinical trial for IDE849 in DLL3 upregulated solid tumor indications, including SCLC, NETs, and NECs, and melanoma (NCT07174583). The study will be enrolling patients globally, including in North America, Europe, Australia, South America, and Asia. In this ongoing Phase 1 dose escalation study, IDE849 is currently evaluating a 3.5 mg/kg IV dose once every 3-weeks (Q3W). Next, to determine the recommended Phase 2 dose (RP2D), IDEAYA is also enrolling patients in a IDE849 expansion cohort at the 2.4 mg/kg IV dose Q3W, where multiple partial responses (PRs) have been observed by RECIST 1.1, including 3 PRs out of 4 SCLC patients pre-treated with IMDELLTRA® (tarlatamab-dlle). The preliminary safety and efficacy profile observed to date in the IDEAYA sponsored study is consistent with the clinical data presented by our China-region partner Jiangsu Hengrui Pharmaceuticals Co. Ltd., at the IASLC World Conference on Lung Cancer 2025 (WCLC 2025).In addition, IDE849 is being evaluated in a clinical combination with IDEAYA's potential first-in-class Phase 1 PARG inhibitor, IDE161. IDEAYA has presented preclinical combination mechanism and synergy efficacy data of IDE161/PARG with TOP1-payload based ADCs at WCLC 2025. IDE161 prevents the removal of poly(ADP-ribose) chains generated by PARP during the DNA damage response, leading to persistent PARylation and impaired resolution of DNA repair complexes. Together with TOP1-payload ADCs, this unique mechanism-of-action results in sustained TOP1 cleavage complexes and the accumulation of DNA damage that delivers enhanced anti-tumor activity. We believe this potential first-in-class combination has the potential to enhance durability of IDEAYA's TOP1-payload based ADC pipeline, including IDE849 and IDE034 (Phase 1 B7H3/PTK7 Bispecific TOP1 ADC).DLL3 has been reported to be upregulated in multiple solid tumor types, including in SCLC, NETs, NSCLC, melanoma, among others. DLL3 has limited extracellular expression in normal tissues, making it a promising potential therapeutic target in these solid tumors, for which there remains significant unmet medical need.About IDEAYA BiosciencesIDEAYA is a precision medicine oncology company committed to the discovery and development of targeted therapeutics for patient populations selected using molecular diagnostics. IDEAYA's approach integrates capabilities in identifying and validating translational biomarkers with drug discovery to select patient populations most likely to benefit from its targeted therapies.

(NASDAQ: IDYA), a leading precision medicine oncology company, today announced that the first patient has been enrolled in its Phase 1 clinical trial evaluating IDE892, an investigational MTA-cooperative PRMT5 inhibitor being developed for patients with MTAP-deleted solid tumors, including non-small cell lung cancer and pancreatic cancer.  The trial will assess safety, tolerability, pharmacokinetics, and pharmacodynamics of IDE892 as a monotherapy agent and in combination with IDE397, IDEAYA's MAT2A inhibitor, in mid-2026.  Dual inhibition of IDE892 and IDE397 has demonstrated durable and well-tolerated tumor regressions in preclinical MTAP-deleted tumor models, including in NSCLC.







"We are excited to have enrolled the first patient in our Phase 1 clinical trial evaluating IDE892 in patients with MTAP-deleted solid tumors, including non-small cell lung cancer and pancreatic cancer.  We designed IDE892 with potential best-in-class properties, including specific biophysical and pharmacokinetic properties that we believe will maximize its therapeutic window and clinical efficacy, both as a monotherapy agent and as a combination partner with our MAT2A inhibitor, IDE397.  Next, we look forward to advancing our first-in-class CDKN2A-defiency program to progress our broader corporate strategy of enabling wholly owned rational combinations targeting MTAP-deletion," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.IDE892 was designed to be a potential best-in-class PRMT5 inhibitor, with ~1,400-fold selective binding to MTA-PRMT5 versus SAM-PRMT5 complexes and observed single-digit nano-molar potency in endogenous MTAP-deleted cell lines, and greater than 50-fold potency differential in MTAP-deleted versus MTAP wild type HCT116 isogenic cell lines.  In addition, IDE892 inhibited the arginine dimethylation of a key PRMT5 substrate involved in mRNA splicing, spliceosome protein SmB (SmB-SDMA), with pico-molar potency in MTAP-deleted cell lines with greater than 100-fold potency differential versus an MTAP wild type cell line.  IDE892 has demonstrated monotherapy regressions in MTAP-deleted preclinical models, and durable complete responses in combination with IDE397. Loss of MTAP leads to the accumulation of methylthioadenosine (MTA) and increased dependence on PRMT5 and MAT2A, two key enzymes involved in methylation and RNA splicing.  In MTAP-deleted tumors, this biology establishes a robust synthetic lethal vulnerability that underpins the mechanistic rationale for combining IDE892 and IDE397.  In preclinical studies, dual inhibition of PRMT5 and MAT2A with the combination of IDE892 and IDE397 resulted in potent anti-tumor activity in MTAP-deleted tumor models, including complete and durable responses at well-tolerated doses below those required for monotherapy activity.IDEAYA has also advanced its CDKN2A-deficiency program and is on track to select a potential first-in-class development candidate in H2 2026 with a target IND in H1 2027.  IDEAYA has demonstrated robust monotherapy efficacy with its CDKN2A lead in multiple preclinical models, including in a KRAS mutation pancreatic model.  IDEAYA plans to evaluate its CDKN2A-deficiency program preclinically as a monotherapy agent, and in combination with assets in its MTAP-deletion portfolio and potentially other RAS and KRAS targeted assets.  CDKN2A-defiency is common in cancer, with a prevalence of over 80% in pancreatic cancer (M. Schutte, et al., Cancer Research, 1997; IDEAYA analysis, TCGA) and is typically co-deleted in MTAP-deletion solid tumors and a common co-alteration with KRAS mutations, particularly in pancreatic cancer, creating rational combination opportunities with MTAP-deletion and KRAS targeted therapies, respectively.As part of IDEAYA's strategic prioritization of its proprietary MTAP-deleted pipeline, including IDE397 and IDE892, and the advancement of its CDKN2A-deficiency program, the company has deprioritized its clinical combination activities with Trodelvy and will be concluding enrollment in the ongoing Phase 1/2 trials with Gilead.  Based on preliminary data from these trials supporting the mechanistic rationale for the combination in MTAP-deleted cancers, IDEAYA may evaluate additional combinations between IDE397 and other TOP1 payload ADCs in this setting, including IDE034, its B7H3/PTK7 bispecific TOP1 ADC. MTAP deletion is estimated to occur in 15–20% of non-small cell lung cancer, up to 40% of pancreatic cancer, and approximately 15% of all solid tumors, and is commonly co-deleted with CDKN2A due to the proximity of the two genes on chromosome 9p21.  There are no approved therapies for patients with MTAP deletion, highlighting the significant unmet need and important new opportunities for precision therapies.About IDEAYA BiosciencesIDEAYA is a precision medicine oncology company committed to the discovery, development, and commercialization of transformative therapies for cancer.  Our approach integrates expertise in small-molecule drug discovery, structural biology and bioinformatics with robust internal capabilities in identifying and validating translational biomarkers to develop tailored, potentially first-in-class targeted therapies aligned to the genetic drivers of disease.  We have built a deep pipeline of product candidates focused on synthetic lethality and antibody-drug conjugates, or ADCs, for molecularly defined solid tumor indications.  Our mission is to bring forth the next wave of precision oncology therapies that are more selective, more effective, and deeply personalized with the goal of altering the course of disease and improving clinical outcomes for patients with cancer.Forward-Looking StatementsThis press release contains forward-looking statements, including, but not limited to, statements related to the potential best-in-class profile, safety, efficacy and therapeutic benefit of IDE892, IDE397 and IDEAYA's CDKN2A-deficiency program; the mechanistic rationale and potential clinical benefit of PRMT5 and MAT2A co-inhibition; the timing, progress, design and results of IDE892's Phase 1 clinical trial; the anticipated timing of first-patient-in for the IDE892 and IDE397 combination in mid-2026; the timing of CDKN2A development candidate selection in the second half of 2026 and IND submission in the first half of 2027; the potential for combination strategies involving IDE892, IDE397 and CDKN2A assets; the prevalence of MTAP deletion and CDKN2A deficiency in certain cancers; projected cost savings associated with strategic prioritization decisions; and the potential market opportunity for IDEAYA's product candidates.

PR Newswire (US)

Phase 1 dose escalation trial to determine safety, tolerability and PK of IDE034Potential as a monotherapy and in combination with proprietary PARG inhibitor, IDE161B7H3/PTK7 co-expressed in 30-40% of multiple solid tumor types, including lung, breast, ovarian and colorectal cancersSOUTH SAN FRANCISCO, Calif., Feb. 25, 2026 /PRNewswire/ -- IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a leading precision medicine oncology company, today announced that the first patient has been enrolled in its Phase 1 dose escalation/expansion trial evaluating IDE034, an investigational PTK7/B7H3 bispecific TOP1 ADC. The company is planning to evaluate safety, tolerability and PK of IDE034 as a monotherapy in the Phase 1 trial, and also plans to test combinations with agents that target the DNA damage response (DDR) pathway, such as their proprietary PARG inhibitor, IDE161. Dosing of the first patient with IDE034 triggers a $5 million milestone payment from IDEAYA to Biocytogen, pursuant to the Option and License Agreement between the companies.







"This is an important milestone for IDE034 as well as our broader ADC/DDR portfolio focused on exploring combinations of highly selective TOP1 ADCs with agents targeting the DDR pathway.  We are excited to begin dosing patients with IDE034, a B7H3/PTK7 bispecific ADC that has demonstrated promising signs of efficacy as a monotherapy and synergy in combination with IDE161 across several preclinical tumor cell models. IDE034 is our second proprietary TOP1 ADC, building on the progress we have made with IDE849, our DLL3 TOP1 ADC currently in Phase 1 for SCLC and NEC, and represents another potentially first-in-class therapy for cancer patients in need of new and improved treatment options," said Yujiro S. Hata, President and Chief Executive Officer of IDEAYA Biosciences.IDE034 is a potentially first-in-class B7H3/PTK7 bispecific TOP 1 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. IDEAYA estimates that B7H3/PTK7 are co-expressed in approximately 30-40% of certain large solid tumor types, including lung, breast, ovarian and colorectal cancers, while exhibiting minimal dual antigen expression in normal tissue. In preclinical tumor models, IDE034 has also demonstrated compelling combination potential with IDE161, the company's oral PARG inhibitor, that suggests these mechanisms may synergize to enhance the efficacy and durability of TOP1 ADCs. About IDEAYA BiosciencesIDEAYA is a precision medicine oncology company committed to the discovery, development, and commercialization of transformative therapies for cancer.

The decrease was primarily driven by net cash used in operations, offset by the $210.0 million upfront payment received from Servier related to the exclusive license agreement for darovasertib during the year ended December 31, 2025.Collaboration revenue for the three months ended December 31, 2025, totaled $10.9 million compared to $7.0 million for the three months ended December 31, 2024. Collaboration revenue was recognized for the performance obligations satisfied through December 31, 2025 related to the research and development services that are recognized over time under the Servier exclusive license agreement for darovasertib. As of December 31, 2025, the remaining balance for the research and development services performance obligations is $161.8 million related to the clinical trial cost reimbursements anticipated under the license agreement that will be recognized as IDEAYA collaboration revenue over time as the research and development services are completed.Research and development (R&D) expenses for the three months ended December 31, 2025 totaled $86.6 million compared to $140.2 million for the three months ended December 31, 2024. The decrease was primarily driven by a $75.0 million upfront payment under the license agreement for IDE849 with Hengrui Pharma during the three months ended December 31, 2024, offset by higher clinical trial and CMC manufacturing expenses to support our programs and personnel-related expenses during the three months ended December 31, 2025.General and administrative (G&A) expenses for the three months ended December 31, 2025 totaled $18.8 million compared to $11.0 million for the three months ended December 31, 2024. The increase was primarily due to higher personnel-related expenses, higher consulting and legal patent fees to support company growth and darovasertib commercial preparation activities.The net loss for the three months ended December 31, 2025, was $83.3 million compared to the net loss of $130.3 million for the three months ended December 31, 2024. Total stock compensation expense for the three months ended December 31, 2025, was $11.8 million compared to $9.5 million for the three months ended December 31, 2024.The net loss for the year ended December 31, 2025, was $113.7 million compared to the net loss of $274.5 million for the year ended December 31, 2024.

Awesome press release, lets see where this goes with that press release. 20-22 dollars possible.

"We have made significant progress on our Phase 1/2 tissue-agnostic basket trial evaluating IDE196 in patients with solid tumors harboring GNAQ or GNA11 (GNAQ/11) mutations, including metastatic uveal melanoma (MUM), cutaneous melanoma and colorectal cancer. This clinical trial progress, considered together with recent FDA feedback providing guidance on the regulatory pathway for IDE196 for treatment of MUM, are important enabling steps to advance this clinical-stage program," said Yujiro S. Hata, Chief Executive Officer and President at IDEAYA Biosciences.
IDEAYA continues to advance its MAT2A synthetic lethality program to treat patients having tumors with MTAP deletion. The Company remains committed to the research and development of a differentiated MAT2A inhibitor that could meaningfully enhance patient outcomes across a broad range of indications. IDEAYA also continues to progress its broad pipeline of synthetic lethality programs, including Pol theta for patients having tumors with BRCA or other homologous recombination deficiency (HRD) mutations, and Werner (WRN) for patients having tumors with high microsatellite instability (MSI).
Key highlights for IDEAYA's research and development programs include:
Clinical Program IDE196
IDE196
Advanced IDEAYA's Phase 1/2 tissue-type agnostic basket trial, which was initiated in June 2019 to evaluate IDE196 in solid tumors harboring activating GNAQ/11 mutations, and is entitled "A phase 1/2 study of IDE196 in patients with solid tumors harboring GNAQ/11 mutations or PRKC fusions" (ClinicalTrials.gov Identifier: NCT03947385)
Completed enrollment in the Phase 1 dose escalation portion of the Phase 1/2 clinical trial at sites in the U.S. and Australia
Anticipate selection of the dosing regimen and initiation of the Phase 2 portion of the clinical trial by year-end 2019
Expect to introduce a tablet formulation of IDE196 in Q1 2020 for use in the Phase 2 portion of the clinical trial
Enrolled our first cutaneous melanoma patient harboring a tumor with an activating GNAQ/GNA11 mutation in October 2019, a key milestone for evaluating IDE196 in solid tumors outside of metastatic uveal melanoma (MUM)
Expanded our relationship with Foundation Medicine, participating in their Smart Trials™ program for identification of non-MUM patients having tumors with activating GNAQ/11 mutations for potential enrollment in our Phase 1/2 basket trial
Anticipate release of interim data from the Phase 1/2 basket trial in Q2/Q3 2020
Obtained FDA feedback in End-of-Phase 1 meeting in Q4 2019, providing guidance on the regulatory pathway for IDE196 for treatment of MUM
Company's proposed single-arm Phase 2 IDE196-001 clinical trial may be adequate to support an NDA seeking Accelerated Approval for IDE196 monotherapy in metastatic uveal melanoma (MUM)
The single-arm potentially registration-enabling Phase 2 clinical trial will target enrollment of 60 evaluable MUM patients
The primary endpoint is overall response rate (ORR) as determined by blinded independent central review (BICR), supported by BICR-determined duration of response (DOR) as a secondary endpoint
The 13-week GLP-compliant toxicology studies in 2 species is scheduled to initiate in November 2019, in support of FDA requirement that study results be submitted prior to enrollment of more than approximately 50 patients in the investigational arm of the clinical trial that will support a marketing application
Continued the ongoing Phase 1 clinical trial, entitled "A Phase I, multi-center, open-label, study of LXS196, an oral protein kinase C inhibitor, in patients with metastatic uveal melanoma" (ClinicalTrials.gov Identifier: NCT02601378), being conducted by Novartis
A confirmed Complete Response at the 200 mg BID dose level was observed at month 31 in one of four patients previously reported with confirmed Partial Response out of 30 total (28 evaluable) BID patients in this ongoing monotherapy arm of the Novartis clinical trial
Based on confirmation of the single arm trial design and anticipated rate of enrollment, we are anticipating submission of a New Drug Application (NDA) to the FDA in Q4 2021 to Q1 2022 for IDE196 in MUM.
Synthetic Lethality Preclinical Pipeline
MAT2A
We believe that data presented at the AACR/NCI/EORTC conference in October 2019 demonstrates clinical activity of MAT2A as a biological target in patients having tumors with MTAP deletion.
Continuing our preclinical evaluation of potential drug candidates, including in the HCT116 engineered in-vivo model, and in multiple endogenous in-vivo models
Goal is to select a MAT2A inhibitor development candidate in the first half of 2020 with differentiated properties relative to Agios' presented published compounds and Agios' publicly-disclosed properties of AG270
Expect to file an IND for a differentiated MAT2A inhibitor development candidate in second half of 2020
"We continue to aggressively progress our programs, expand our capabilities and enhance our team. IDEAYA remains committed to its vision of improving lives through transformative precision medicines, and believes that the IDE196 tissue-type agnostic basket trial and our pipeline of synthetic lethality programs are key elements of this goal," said Yujiro S. Hata, Chief Executive Officer and President at IDEAYA Biosciences.
Corporate Updates
IDEAYA anticipates that existing cash, cash equivalents and short-term marketable securities of $109.4 million (as of September 30, 2019) will be sufficient to fund planned operations into the third quarter of 2021.

As of September 30, 2019, IDEAYA had cash, cash equivalents and short-term marketable securities totaling $109.4 million. This compared to cash, cash equivalents and short-term marketable securities of $90.0 million at December 31, 2018. The increase was primarily due to the receipt of $50.2 million in net proceeds from IDEAYA's initial public offering, which was completed in May 2019, offset by cash used in operations.
Research and development expenses for the three months ended September 30, 2019 totaled $8.9 million compared to $12.5 million for the same period in 2018. The decrease was primarily due to license fees for our IDE196 license agreement with Novartis during the three months ended September 30, 2018, offset by an increase in costs in connection with IDEAYA's Phase 1/2 clinical trial to evaluate IDE196 in solid tumors, and costs for personnel, consulting, and laboratory supplies in support of our research programs during the three months ended September 30, 2019.
General and administrative expenses for the three months ended September 30, 2019 totaled $2.7 million compared to $1.1 million for the same period in 2018. The increase was primarily due to an increase in costs for personnel, directors' and officers' liability insurance premiums, and professional fees in connection with becoming a publicly traded company as well as external legal patent expenses for our product candidates.
The net loss for the three months ended September 30, 2019 was $11.0 million compared to $13.0 million for the same period in 2018. Total stock compensation expense for the three months ended September 30, 2019 was $0.5 million compared to $0.3 million for the same period in 2018.

IDEAYA anticipates that existing cash, cash equivalents and short-term marketable securities of $109.4 million (as of September 30, 2019) will be sufficient to fund planned operations into the third quarter of 2021.
