News Release Details

Positive preliminary Phase 1b data in SEACRAFT-1 NRASm melanoma cohort bolsters conviction in ongoing SEACRAFT-2 registrational trial; Stage 1 randomized data expected in 2025

Strong execution across potentially best-in-class RAS targeting franchise; planned IND submissions on track

Robust balance sheet with cash, cash equivalents, and marketable securities of $463 million as of September 30, 2024, is expected to fund operations into H1 2027

SAN DIEGO, Nov. 12, 2024 (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 ended September 30, 2024.

“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 36^th EORTC-NCI-AACR (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 36^th EORTC-NCI-AACR (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.

Key Upcoming Milestones

• SEACRAFT-2: Randomized pivotal Phase 3 trial for naporafenib plus trametinib in patients with NRASm melanoma
  • Phase 3 Stage 1 randomized dose optimization data expected to be reported in 2025
• AURORAS-1: Phase 1 trial for ERAS-0015 (pan-RAS molecular glue) in patients with RASm solid tumors
  • IND filing expected in H1 2025
  • Initial Phase 1 monotherapy data in relevant tumor types expected to be reported in 2026
• BOREALIS-1: Phase 1 trial for ERAS-4001 (pan-KRAS inhibitor) in patients with KRASm solid tumors
  • IND filing expected in Q1 2025
  • Initial Phase 1 monotherapy data in relevant tumor types expected to be reported in 2026

Third Quarter 2024 Financial Results

Cash Position: Cash, cash equivalents, and marketable securities were $463.3 million as of September 30, 2024, compared to $322.0 million as of December 31, 2023. Erasca expects its current cash, cash equivalents, and marketable securities balance of $463.3 million to fund operations into the first half of 2027.

Research and Development (R&D) Expenses: R&D expenses were $27.6 million for the quarter ended September 30, 2024, compared to $25.2 million for the quarter ended September 30, 2023. The increase was primarily driven by increases in expenses incurred in connection with clinical trials, preclinical studies, and discovery activities, partially offset by decreases in personnel costs, including stock-based compensation expense, and outsourced services and consulting fees.

General and Administrative (G&A) Expenses: G&A expenses were $9.6 million for the quarter ended September 30, 2024, compared to $9.4 million for the quarter ended September 30, 2023.

Net Loss: Net loss was $31.2 million, or $(0.11) per basic and diluted share, for the quarter ended September 30, 2024, compared to $30.4 million, or $(0.20) per basic and diluted share, for the quarter ended September 30, 2023.
