- Additional unconfirmed responses noted at doses above 8 mg.
- Safety profile remains favorable with no dose-limiting toxicities and predominantly low-grade adverse events.
- Pharmacokinetics are linear with no evidence of exposure plateau.
- ERAS-4001 (Pan-KRAS inhibitor):

Guidance, Outlook, and Risks
Anticipated Milestones:
- ERAS-0015: Initial Phase 1 monotherapy data expected in the first half of 2026; expansion and combination cohorts planned for the second half of 2026; data readouts planned for 2027.
- ERAS-4001: Initial Phase 1 monotherapy data expected in the second half of 2026; expansion and combination cohorts planned for 2027.
Risks and Contingencies:
The filing includes extensive forward-looking statement disclaimers. Key risks include the possibility that unconfirmed responses may not become confirmed, preliminary results may not predict final outcomes, and potential delays in trial enrollment or data readouts. The Company also notes risks related to its dependence on third-party manufacturers, the unproven nature of its RAS/MAPK pathway approach, and the sufficiency of its cash resources to fund operations.
Investor Verification Checklist
- Verify the status of the two confirmed partial responses and one unconfirmed partial response in the AURORAS-1 trial upon future data readouts.
- Monitor the Company's cash runway and capital resources as referenced in the risk factors, given the lack of revenue and high R&D costs.
- Confirm the timeline for the initiation of expansion cohorts for both ERAS-0015 and ERAS-4001 in late 2026.
- Review the full corporate presentation (Exhibit 99.1) for detailed strategic updates not fully captured in this summary.
- Assess the potential for unconfirmed responses to fail confirmation during follow-up evaluations.
