(Nasdaq: ERAS), a clinical-stage precision oncology company singularly focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers, today announced dosing of the first patient in the HERKULES-1 Phase 1b trial evaluating ERK1/2 inhibitor ERAS-007 in combination with SHP2 inhibitor ERAS-601 (together, Erasca’s first MAPKlamp) in patients with RAS/MAPK pathway-altered solid tumors. “We are pleased with our team’s efficient execution that resulted in dosing the first patient in our MAPKlamp trial in 2022 ahead of schedule,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “ERK and SHP2 inhibition with ERAS-007 and ERAS-601 targets critical downstream and upstream nodes in the RAS/MAPK pathway, offering a rational approach that is supported by early clinical data that we presented at our R&D Day in September. Notably, we reported four responses in nine patients with BRAF-driven tumors to either monotherapy ERAS-007 or ERAS-601. Three of these responses were in tumors with BRAF Class 2 or 3 alterations, including a confirmed response to monotherapy SHP2 inhibition in a patient with a BRAF Class 3 alteration, which is dependent on upstream receptor tyrosine kinase (RTK) activation. We look forward to exploring the potential to address the high unmet need in these BRAF subtypes, which have no approved targeted therapies and represent up to 25% of all BRAF-driven tumors.” The MAPKlamp portion of HERKULES-1 will initially examine the safety, tolerability, and preliminary efficacy of ERAS-007 in combination with ERAS-601 in patients with RAS/MAPK pathway-altered solid tumors. After a recommended dose is determined, the Phase 2 expansion portion will further evaluate the safety and efficacy of the combination in patients with different mutational subtypes, including BRAF Class 2 and 3 patients. ERAS-007 and ERAS-601 had favorable monotherapy safety and tolerability profiles w...
