Abstract 390 - ERAS-0015 is a pan-RAS molecular glue with best-in-class potential in RAS mutant solid tumors (GlobeNewswire) - "Erasca...presented new preclinical data reinforcing the best-in-class profiles of Erasca’s RAS-targeting franchise at the American Association for Cancer Research (AACR) Annual Meeting....ERAS-0015 demonstrated favorable pharmacokinetic properties including longer residence time and greater tissue exposure that led to robust anti-tumor activity alone and in combination at doses lower than the leading pan-RAS molecular glue in development....ERAS-0015 dose-dependently formed a ternary complex with active state RAS and CypA, which blocks formation of additional downstream effector complexes. Potent inhibition of proliferation with ERAS-0015 across a panel of cell lines spanning diverse tumor tissues and RAS mutations....Promising monotherapy and combination activity across multiple RAS mutant models."

ERAS-0015 is a pan-RAS molecular glue with best-in-class potential in RAS mutant solid tumors (AACR 2025) - "ERAS-0015's roughly 8-20-fold higher binding affinity to cyclophilin A (CYPA) is thought to contribute to its higher in vitro cellular potency as well as favorable ADME and PK properties resulting in a longer residence time and greater exposure in tumor tissues as compared to RMC-6236. These favorable properties enabled ERAS-0015 to achieve comparable tumor growth inhibition (TGI) relative to RMC-6236 at 1/8th-1/10th the dose across multiple KRAS mutant CDX models irrespective of histology or specific mutation.ERAS-0015 demonstrated promising preclinical activity across multiple RAS mutant models supporting IND filing in 1H 2025."
