Erasca Announces IND Clearance for RAS-Targeting Franchise, Prioritizes Naporafenib Partnership Opportunities

Erasca has received IND clearance for ERAS-0015, a pan-RAS molecular glue, and submitted an IND application for ERAS-4001, a potential first-in-class pan-KRAS inhibitor. The company has prioritized its RAS-targeting franchise and is exploring partnership opportunities for naporafenib, a pan-RAF inhibitor, to extend its cash runway to the second half of 2028. Initial data for ERAS-0015 and ERAS-4001 is expected in 2026.

Erasca, Inc. (Nasdaq: ERAS) has made significant strides in its RAS-targeting franchise, receiving Investigational New Drug (IND) clearance for ERAS-0015 and submitting an IND application for ERAS-4001. These developments come on the heels of the company's strategic focus on its RAS-targeting pipeline and its exploration of partnership opportunities for naporafenib, a pan-RAF inhibitor, to extend its cash runway to the second half of 2028.

ERAS-0015, a pan-RAS molecular glue, has received IND clearance for patients with RAS-mutant (RASm) solid tumors, marking a milestone in Erasca's efforts to target significant cancer pathways. The company plans to evaluate ERAS-0015 monotherapy in a Phase 1 trial (AURORAS-1) with initial data expected in 2026. ERAS-4001, a potential first-in-class pan-KRAS inhibitor, has been submitted for IND approval for patients with KRAS-mutant (KRASm) solid tumors. The planned BOREALIS-1 Phase 1 trial will assess ERAS-4001 monotherapy, also with initial data expected in 2026.

Erasca's financial report as of March 31, 2025, revealed a robust cash position of $411 million, extending its operational funding through the second half of 2028. The company's strategic focus on its RAS-targeting franchise and the potential for partnerships to extend its cash runway underscore its commitment to addressing significant healthcare needs in oncology.

While the company reported a net loss of $31.0 million for the quarter ended March 31, 2025, this was a decrease from the previous quarter's net loss of $35.0 million. The decrease in net loss was driven by a decrease in research and development expenses, primarily due to decreases in personnel costs, clinical trial expenses, and facilities-related expenses. General and administrative expenses also decreased, driven by lower legal fees and insurance costs.

Erasca's progress in its RAS-targeting pipeline, coupled with its strong cash position and strategic focus, positions the company well for clinical advancement and potential partnerships. The company's ability to deliver initial Phase 1 monotherapy data for both ERAS-0015 and ERAS-4001 in 2026 may provide critical insights into the effectiveness of these promising therapies.
