Item 8.01

Other Events.

On February 8, 2023, Erasca, Inc. (the Company) announced certain strategic decisions regarding its clinical development efforts that have resulted in the Company extending its projected cash runway from the first half of 2025 to the second half of 2025, and an acceleration of the Company’s timing for certain anticipated data readouts.

The announced strategic decisions consisted of focusing more of the Company’s resources on: (i) the acceleration of the execution of the SEACRAFT-1 trial for naporafenib; and (ii) those sub-studies for ERAS-007 and ERAS-601 that are supported for further development by the strongest preclinical rationale and/or initial encouraging clinical activity. As a result of these decisions, the Company has revised or affirmed its prior guidance regarding anticipated data readouts to reflect the following: (i) the anticipated SEACRAFT-1 data readout in RAS Q61X solid tumors has been accelerated to Q2 2024 – Q4 2024 (vs. previous guidance of H2 2024 – H1 2025); (ii) the anticipated FLAGSHP-1 dose expansion data readout in human papillomavirus (HPV)-negative advanced head and neck squamous cell carcinoma (HNSCC) has been accelerated to H1 2024 (vs. previous guidance of calendar year 2024); and (iii) the anticipated HERKULES-3 dose expansion data readout in BRAF-mutated colorectal cancer (CRC) has been affirmed between H2 2023 – H1 2024. The Company’s revised or affirmed milestone guidance is set forth on the slide attached as Exhibit 99.1 to this report.

Actual results may differ from those set forth in this press release due to the risks and uncertainties inherent in our business, including, without limitation: results from preclinical studies or early clinical trials not necessarily being predictive of future results; delays in our preclinical and clinical development programs; our dependence on third parties in connection with manufacturing, research, and preclinical and clinical testing; unexpected adverse side effects or inadequate efficacy of our product candidates that may limit their development, regulatory approval, and/or commercialization; the inability to realize any benefits from our current licenses, acquisitions, and collaborations and any future licenses, acquisitions, or collaborations; regulatory developments in the United States and foreign countries; our ability to obtain and maintain intellectual property protection for our product candidates; our ability to fund our operating plans with our current cash, cash equivalents, and marketable securities; our ability to maintain undisrupted business operations due to the COVID-19 pandemic and global geopolitical events, such as the ongoing conflict between Russia and Ukraine; unstable market and economic conditions having serious adverse consequences on our business, financial condition and stock price; and other risks described in our prior filings with the Securities and Exchange Commission (SEC), including under the heading “Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2021, and any subsequent filings with the SEC.
