To this end, ERAS-007 was evaluated in preclinical models in combination with encorafenib + cetuximab in BRAFV600E CRC and with palbociclib in KRASmut CRC. ERAS-007 demonstrated monotherapy activity and combination benefit in cell-based assays as well as superior combination efficacy in vivo relative to respective monotherapy control arms.In summary, ERAS-007 demonstrates promising preclinical activity across a wide range of RAS/MAPK pathway-driven CRC models both as a monotherapy and in combination that support further exploration in the clinic.
