"We made significant progress across our pipeline programs and are pleased with the pace of our execution. Positive preliminary data from SEACRAFT-1, which we reported at the 36th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) (ENA) Symposium last month, has refined our clinical development focus of naporafenib plus trametinib on patients with NRAS-mutant (NRASm) melanoma, and importantly, heightens our conviction in the ongoing SEACRAFT-2 registrational trial targeting a similar patient population," said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. "SEACRAFT-2 has the potential for approval based on the high unmet need of these patients as well as the alignment with US and European regulators on the NRASm melanoma indication. We expect randomized dose optimization data from Stage 1 of this Phase 3 trial in 2025."

Dr. Lim added, "Our RAS targeting franchise, which includes a potential best-in-class pan-RAS molecular glue ERAS-0015 and a potential first-in-class pan-KRAS inhibitor ERAS-4001, holds significant promise to help a broad range of patients with RAS-mutant (RASm) solid tumors. Following the in-licensing of these molecules in May, we have rapidly and effectively confirmed in-house the potential best-in-class profiles of both agents and executed across multiple activities to support their planned investigational new drug (IND) application submissions, which remain on track for the first quarter of 2025 for ERAS-4001 and the first half of 2025 for ERAS-0015. We continue to be well capitalized with an anticipated cash runway into the first half of 2027 and are poised for strong execution across our pipeline."

Research and Development (R&D) Highlights

•
Presented Promising SEACRAFT-1 Phase 1 Data: In October 2024, Erasca presented Phase 1b SEACRAFT-1 data for naporafenib plus trametinib (MEKINIST) in patients with locally advanced unresectable or metastatic solid tumor malignancies with RAS Q61X mutations at the 36th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) (ENA) Symposium on Molecular Targets and Cancer Therapeutics and as part of a company R&D update. Data support rationale for pursuing an NRASm melanoma indication and reinforces the potential of the ongoing Phase 3 SEACRAFT-2 registrational trial.
•
Announced Progress Across RAS Targeting Franchise: In October 2024, Erasca presented a program update for pan-RAS molecular glue ERAS-0015 and pan-KRAS inhibitor ERAS-4001 as part of a company R&D update, highlighting the rapid progress across both programs including in-house
confirmation of potential best-in-class profiles for both agents and advancement of activities to support planned IND application submissions.
