- IDE892 is a potential best-in-class PRMT5 inhibitor with 1,400-fold selective MTA-PRMT5 cooperative binding vs SAM-PRMT5 cooperative binding, and CYP3A4 IC50 greater than 45 micromolar with no time-dependent inhibition of the 7 major cytochrome P450s
- IDE892 Phase 1/2 escalation has cleared multiple dose cohorts and projected efficacious target exposures have been achieved to initiate the Part 2 monotherapy expansion. The IDE892 escalation is ongoing in parallel and the MTD has not yet been reached
- IDE892 and IDE397 combination escalation are ongoing in MTAP NSCLC and PDAC, and IDE892 and pan-RAS combination FPI in MTAP PDAC is targeted for H2 2026
- MTAP-deletion is estimated to occur in up to 40% of PDAC and ~15% of NSCLC
- IDEAYA is targeting a MTAP/CDKN2A, KRAS, and Pancreatic Cancer R&D Day in Q4 2026. Topics will include rational combination strategies to target the underlying tumor heterogeneity and adaptive plasticity in PDAC and other solid tumor indications
