- IDEAYA entered into a clinical collaboration with Roche to evaluate IDE892, IDEAYA's potential best-in-class Phase 1 MTA-cooperative PRMT5 inhibitor, in combination with RG6505, Roche's Phase 1 pan-RAS inhibitor, in MTAP-deleted, RAS-mutant pancreatic ductal adenocarcinoma
- IDEAYA will sponsor the clinical trial, and there will be joint IDEAYA and Roche governance to oversee the study
- MTAP-deletion is estimated to occur in up to
40% of PDAC
"We are pleased to evaluate the clinical combination of IDE892 with RG6505 in MTAP-deleted RAS-mutant PDAC," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences. "This collaboration aligns with our broader clinical strategy to evaluate rational combinations with assets in our MTAP-deletion portfolio, and there remains especially high unmet need in PDAC."
IDE892 was designed to be a potential best-in-class PRMT5 inhibitor and has demonstrated robust monotherapy regressions in MTAP-deleted preclinical models. IDEAYA is evaluating IDE892 in a Phase 1 dose escalation clinical trial in MTAP-deleted solid tumors and plans to initiate Phase 1 combination cohorts, in PDAC with RG6505 as well as in NSCLC and other solid tumors with IDE397, IDEAYA's proprietary MAT2A inhibitor.
MTAP deletion is estimated to occur in up to
Under the clinical collaboration, IDEAYA and Roche each retain all commercial rights to their respective compounds, including as monotherapy and as combination therapies. There will be joint IDEAYA and Roche governance to oversee the clinical combination study. The clinical collaboration also has the ability to evaluate a combination triplet with IDE892, RG6505, and IDE397, IDEAYA's Phase 2 MAT2A inhibitor, upon joint IDEAYA and Roche approval.
