Erasca, Inc. (Nasdaq: ERAS), a clinical-stage precision oncology company focused on RAS/MAPK pathway-driven cancers, has announced promising early data regarding its investigational drug ERAS-0015. The company is advancing its RAS-targeting program, building on confirmed partial responses across multiple tumor types that carry different RAS mutations. This development is accompanied by favorable safety and pharmacokinetics data observed during the drug's dose escalation.

Clinical Advancements and Milestones

As indicated by Jonathan E. Lim, M.D., chairman and CEO of Erasca, the company continues to execute its operational strategies effectively, resulting in swift clinical developments. ERAS-0015 is currently enrolling patients ahead of schedule, enhancing the data pipeline for reporting initial Phase 1 results:

  • Early Data Release: Initial Phase 1 monotherapy data for ERAS-0015 is expected in the first half of 2026.
  • Expansion Plans: Monotherapy expansion and combination dose escalation cohorts are set to commence in the latter half of 2026.
  • Future Data Projections: Detailed expansion and combination data are targeted for release in 2027.

ERAS-0015: A Potential Breakthrough in Cancer Therapy

ERAS-0015 is recognized as a potential best-in-class oral pan-RAS molecular glue, showing encouraging potential to inhibit RAS signaling. Noteworthy findings from the ongoing AURORAS-1 Phase 1 trial include:

  • Multiple confirmed and unconfirmed partial responses at an initial dose of 8 mg QD.
  • No dose-limiting toxicities and primarily low-grade adverse events reported.
  • Favorable pharmacokinetics observed, indicating a linear response across evaluated dose levels.

Looking Ahead: ERAS-4001 and Broader Implications

In parallel, Erasca is advancing ERAS-4001, a first-in-class pan-KRAS inhibitor, in the BOREALIS-1 Phase 1 trial, with monotherapy data anticipated in the second half of 2026. Key aspects include:

  • Potent in vitro activity against various KRAS mutations.
  • No observed activity against HRAS or NRAS wildtype proteins, potentially widening the drug’s therapeutic window.
