IDEAYA Biosciences (NASDAQ: IDYA) announced a clinical collaboration with Genentech, a member of the Roche Group, to evaluate IDEAYA’s Phase 1 MTA-cooperative PRMT5 inhibitor IDE892 in combination with Genentech’s KRAS G12D inhibitor GDC-7035 (RG6620) in patients with MTAP-deleted, KRAS G12D-mutant pancreatic ductal adenocarcinoma (PDAC).

Genentech will sponsor the combination trial and IDEAYA will supply IDE892, with joint governance overseeing the study. According to IDEAYA, IDE892 shows approximately 1,400-fold selectivity for MTA-PRMT5 versus SAM-PRMT5 cooperative binding, favorable CYP450 interaction data, and is already in Phase 1 dose escalation and combination cohorts across MTAP-deleted solid tumors.

5 terms
mta-cooperative prmt5 inhibitor medical
"its investigational, potential best-in-class MTA-cooperative PRMT5 inhibitor"
A mta-cooperative PRMT5 inhibitor is a type of experimental cancer drug that blocks the PRMT5 enzyme more effectively when methylthioadenosine (MTA) is present inside tumor cells. Think of PRMT5 as a machine and MTA as a piece that makes the machine easier to disable; drugs that exploit this interaction can target tumors with high MTA levels, which matters to investors because it affects which patients may benefit, how narrowly the drug’s market is defined, and how clinical trials and regulatory paths are designed.
mtap-deleted medical
"in patients with pancreatic ductal adenocarcinoma (PDAC) harboring both an MTAP-deletion"
mtap-deleted describes cells or tumors that have lost the MTAP gene, a molecular ‘tool’ normally involved in a basic cellular recycling pathway. For investors, this matters because that missing tool can create a specific weakness drug developers can target, helping identify which patients a therapy might work for and shaping clinical trial design, potential market size, and the commercial value of precision medicines.
pancreatic ductal adenocarcinoma medical
"patients with pancreatic ductal adenocarcinoma (PDAC)"
A fast-growing cancer that starts in the cells lining the pancreas’ small ducts; it is the most common and aggressive form of pancreatic cancer. It matters to investors because its severity and limited treatment options drive high unmet medical need, large potential markets for effective drugs or diagnostics, and strong sensitivity of company valuations to clinical trial results, regulatory approvals, or changes in treatment guidelines—similar to how fixing a main leak can prevent major damage in a building.
cyp3a4 technical
"IDE892 has a CYP3A4 IC50 greater than 45 micromolar"
CYP3A4 is a liver enzyme that acts like a chemical filter, breaking down a large share of prescription drugs and other substances in the body. Investors pay attention because how a drug is processed by CYP3A4 affects dosing, side effects, drug interactions, clinical trial outcomes and regulatory approvals, all of which can significantly influence a drug’s safety profile, market potential and revenue prospects.
ic50 technical
"IDE892 has a CYP3A4 IC50 greater than 45 micromolar"
IC50 is the concentration of a drug or compound needed to reduce a specific biological activity by half, commonly used to compare how potent experimental treatments are in laboratory tests. For investors, a lower IC50 often signals a stronger candidate that may require smaller doses, influence development costs, safety margins and competitive positioning, so it offers an early measure of technical promise though it does not guarantee clinical or commercial success.

  • IDEAYA entered into a clinical collaboration to evaluate IDE892, IDEAYA's potential best-in-class Phase 1 MTA-cooperative PRMT5 inhibitor, in combination with RG6620, Genentech's Phase 1 KRAS G12D inhibitor, in MTAP-deleted, KRAS G12D-mutant pancreatic ductal adenocarcinoma
  • Genentech will sponsor the clinical trial, and there will be joint governance to oversee the study

SOUTH SAN FRANCISCO, Calif., Aug. 19, 2026 /PRNewswire/ -- IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced it has entered into a clinical collaboration with Genentech, a member of the Roche Group, to evaluate the efficacy and safety of IDE892, its investigational, potential best-in-class MTA-cooperative PRMT5 inhibitor, in combination with GDC-7035 (RG6620), Genentech's KRAS G12D inhibitor, in patients with pancreatic ductal adenocarcinoma (PDAC) harboring both an MTAP-deletion and a KRAS G12D mutation. Genentech will sponsor the clinical combination study, and IDEAYA will supply IDE892.

"We are excited to expand our clinical collaboration with Roche to evaluate a second KRAS combination with potential best-in-class MTA-cooperative PRMT5 inhibitor IDE892 for pancreatic cancer patients, where there remains a high unmet medical need. IDEAYA is advancing multiple rational combination strategies for the IDE892 program, including with MAT2A inhibitor IDE397, pan-RAS inhibitors, KRAS G12D inhibitors, and IDEAYA's lead CDKN2A compound," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.

IDE892 has potential best-in-class properties, including approximately 1,400-fold selective MTA-PRMT5 cooperative binding versus SAM-PRMT5 cooperative binding and lack of brain penetrance intended to maximize its therapeutic window, and favorable drug-like properties to enable rational combinations with IDE397, pan-RAS inhibitors, KRAS-mutant specific therapies, and IDEAYA's CDKN2A lead molecule. IDE892 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 assays, positioning IDE892 as a potential best-in-class MTA-cooperative PRMT5 combination partner. IDEAYA is evaluating IDE892 in a Phase 1 dose escalation and expansion clinical trial in MTAP-deleted solid tumors and has initiated a Phase 1 combination cohort in NSCLC and other solid tumors with IDE397, IDEAYA's proprietary MAT2A inhibitor. IDEAYA also plans to initiate a Phase 1 combination cohort with Roche's RG6505 in MTAP-deleted, RAS-mutant PDAC in 2H 2026. The collaboration announced today adds GDC-7035 as an additional KRAS-directed combination partner for IDE892 in MTAP-deleted, KRAS G12D positive PDAC.

MTAP deletions and KRAS G12D mutations are estimated to co-occur in up to approximately 15% of PDAC patients. Combining a PRMT5 inhibitor with a KRAS G12D mutant-specific inhibitor may have the potential to drive deeper and more durable responses for those PDAC patients with co-occurring alterations, who currently have no approved targeted treatment options. 

Under the clinical collaboration, IDEAYA and Genentech each retain all commercial rights to their respective compounds, including as monotherapy and as combination therapies. There will be joint governance to oversee the clinical supply collaboration.
