Item 8.01 Other Events.

On December 11, 2023, Erasca, Inc. (the Company) announced that the United States Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to naporafenib in combination with trametinib (MEKINIST®) for the treatment of adult patients with unresectable or metastatic melanoma who have progressed on, or are intolerant to, an anti‑programmed death-1 (ligand 1) (PD‑(L)1)-based regimen, and whose tumors contain an NRAS mutation (NRASm).

FTD is designed to help drugs reach patients faster by facilitating the development and expediting the review of drugs with the potential to fill an unmet medical need by treating a serious or life-threatening condition. Programs that receive FTD benefit from early and frequent interactions with the FDA during the clinical development process and, if relevant criteria are met, the FDA may consider reviewing portions of a marketing application before the sponsor submits the complete application.

Cautionary Note Regarding Forward-Looking Statements

Erasca cautions you that statements contained in this report regarding matters that are not historical facts are forward-looking statements. The forward-looking statements are based on our current beliefs and expectations and include, but are not limited to: our expectations regarding our ability to realize the benefits from naporafenib receiving FTD from the FDA. Actual results may differ from those set forth in this report due to the risks and uncertainties inherent in our business, including, without limitation: FTD may not result in a more expedited development or regulatory review process, and such a designation does not increase the likelihood that naporafenib in combination with trametinib will receive marketing approval in the United States; FTD does not change the standards for regulatory approval; the FDA may later decide that naporafenib in combination with trametinib no longer meets the conditions for FTD qualification or decide that the time period for FDA review or approval will not be shortened; potential delays in the commencement, enrollment, data readouts, and completion of clinical trials and preclinical studies; 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, 2022, and any subsequent filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and we undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date hereof. All forward-looking statements are qualified in their entirety by this cautionary statement, which is made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
