Item 8.01 Other Events.
On October 24, 2024, Erasca, Inc. (the Company) announced preliminary data from its SEACRAFT-1 Phase 1b trial in an oral presentation at the 36th EORTC-NCI-AACR (ENA) Symposium.
In the Phase 1b trial of naporafenib plus trametinib (MEKINIST®) in patients with locally advanced unresectable or metastatic solid tumor malignancies with RAS Q61X mutations, the preliminary clinical activity of naporafenib plus trametinib in the melanoma cohort include, as of the efficacy cutoff date*:
*Safety data cutoff date was September 3, 2024. Efficacy data cutoff date was September 5, 2024.
Naporafenib plus trametinib has been generally well tolerated as of the safety cutoff date, with mostly low-grade adverse events in the majority of patients. The Company believes that the use of mandatory primary rash prophylaxis helped reduce the frequency and severity of skin toxicities, reduced drug discontinuation rate due to adverse events, and improved the observed tolerability as measured by the increased relative dose intensity, as compared to the prior clinical trials of naporafenib plus trametinib conducted by Novartis, which did not include the use of mandatory primary rash prophylaxis.
The Company believes that the preliminary SEACRAFT-1 data reinforce the potential of the ongoing Phase 3 SEACRAFT-2 trial in patients with NRAS-mutant (NRASm) melanoma. The Company expects to read out randomized dose optimization data from Stage 1 of the SEACRAFT-2 Phase 3 trial in 2025.
Forward-Looking Statements
The Company 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 the Company’s current beliefs and expectations and include, but are not limited to: the Company’s expectations regarding the potential therapeutic benefits and safety profile of its product candidates, including naporafenib; and the planned advancement of the Company’s development pipeline, including the anticipated timing of future data readouts for Stage 1 of the SEACRAFT-2 trial, and other upcoming development milestones. Actual results may differ from those set forth in this report due to the risks and uncertainties inherent in the Company’s business, including, without limitation: preliminary results of a clinical trial are not necessarily indicative of final results and one or more of the clinical outcomes may materially change as patient enrollment continues, following more comprehensive reviews of the data and as more patient data becomes available; the Company’s approach to the discovery and development of product candidates based on the Company’s singular focus on shutting down the RAS/MAPK pathway, a novel and unproven approach; potential delays in the commencement, enrollment, and completion of clinical trials and preclinical studies; the Company’s dependence on third parties in connection with manufacturing, research, and preclinical and clinical testing; unexpected adverse side effects or inadequate efficacy of the Company’s product candidates that may limit their development, regulatory approval, and/or commercialization, or may result in recalls or product liability claims; unfavorable results from preclinical studies or clinical trials; results from preclinical studies or early clinical trials not necessarily being predictive of future results; regulatory developments in the United States and foreign countries; the Company’s ability to obtain and maintain intellectual property protection for the Company’s product candidates and maintain the Company’s rights under intellectual property licenses; the Company’s ability to fund its operating plans with its current cash, cash equivalents, and marketable securities; and other risks described in the Company’s 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, 2023, 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 the Company undertakes 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.
