Potentially best-in-class RAS-targeting franchise advancing with both ERAS-0015 and ERAS-4001 expected to enter the clinic in 2025 Ongoing Phase 3 SEACRAFT-2 registrational trial progressing well with Stage 1 randomized data expected in H2 2025 Robust balance sheet with cash, cash equivalents, and marketable securities of $440 million as of December 31, 2024 is expected to fund operations into H2 2027 SAN DIEGO, March 20, 2025 (GLOBE NEWSWIRE) -- Erasca, Inc. (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 provided business updates and reported financial results for the fiscal quarter and full year ended December 31, 2024. “In 2024, we prepared our RAS-targeting franchise to enter the clinic and further advanced our registrational program for naporafenib. The high enthusiasm for our RAS-targeting franchise is encouraging, particularly as our potential best-in-class pan-RAS molecular glue ERAS-0015 and our potential first-in-class pan-KRAS inhibitor ERAS-4001 approach the clinic. The high prevalence of KRAS alterations and the significant unmet need among these patients offer substantial opportunities for both candidates in key indications, namely colorectal, lung, pancreatic, and other solid tumor cancers,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “The SEACRAFT-2 trial is progressing well, and with FDA Fast Track Designation (FTD) granted in NRASm melanoma, this combination has the potential to be first-to-market in this area of high unmet need with no approved targeted therapies.” Dr. Lim added, “We have an exciting year ahead focused on shutting down RAS and expect multiple value drivers in 2025 and beyond. In the second half of 2025, we expect Stage 1 randomized data from SEACRAFT-2 in patients with NRASm melanoma. For our RAS-targeting franchise, we expect investigational new drug (IND) submissions for ERAS-0015 in mid-second quarter and for ERAS-4001 in the second quarter of 2025. We continue to be well capitalized and capital efficient and have revised our cash runway guidance from the first half of 2027 to the second half of 2027.” Research and Development (R&D) Highlights RAS-Targeting Franchise Announced Progress Across RAS-Targeting Franchise: In October 2024, Erasca presented a program update for the pan-RAS molecular glue ERAS-0015 and pan-KRAS inhibitor ERAS-4001 as part of a virtual investor event. The updates highlighted the rapid progress observed across both programs including in-house confirmation of potential best-in-class profiles for both agents and completion of many key activities to support IND submissions. In-Licensed Potential Best-in-Class and First-in-Class RAS-Targeting Franchise: In May 2024, Erasca announced exclusive license agreements for two preclinical RAS programs—a potential best-in-class pan-RAS molecular glue (ERAS-0015) and a potential first-in-class pan-KRAS inhibitor (ERAS-4001). ERAS-0015 and ERAS-4001 are potent, orally bioavailable molecules with complementary RAS inhibitory mechanisms. ERAS-0015 has the potential to address unmet medical needs in approximately 2.7 million patients who are diagnosed annually worldwide with RAS-mutant tumors, including the more than 2.2 million patients with KRAS-mutant tumors whom ERAS-4001 could also address. Naporafenib Program Presented Promising SEACRAFT-1 Phase 1b Data: In October 2024, Erasca announced promising initial Phase 1b data for naporafenib plus trametinib (MEKINIST®) in the melanoma cohort of SEACRAFT-1 at the 36th EORTC-NCI-AACR (ENA) Symposium on Molecular Targets and Cancer Therapeutics. Efficacy and tolerability data supported the rationale for pursuing an NRASm melanoma tissue-specific indication and reinforced the potential of the ongoing Phase 3 SEACRAFT-2 registrational trial, which was initiated in the second quarter of 2024. Analysis of Median Overall Survival (mOS) Data for Naporafenib and Trametinib: In March 2024, a pooled analysis of patients with NRASm melanoma dosed with the combination of naporafenib and trametinib at two different doses across two different trials (Phase 1b and Phase 2) showed an mOS of 13.0 and 14.1 months, respectively. The pooled dataset compared favorably relative to historical benchmarks. Corporate Highlights Extended Cash Runway into H2 2027: In 2024, Erasca raised $251 million in equity financings, including a $45 million oversubscribed private placement financing and a $184 million oversubscribed underwritten offering, both of which were led by high-quality new and existing healthcare-focused investors and both of which helped extend our anticipated cash runway into the second half of 2027.
