Erasca (Nasdaq: ERAS) announced that the U.S. Food and Drug Administration granted Fast Track Designation (FTD) to its oral pan-RAS molecular glue ERAS-0015 for treating patients with metastatic pancreatic adenocarcinoma. ERAS-0015 is designed to inhibit RAS signaling and is being evaluated for a potential best-in-class profile.
According to Erasca, FTD, which supports development of therapies for serious conditions with unmet needs, may provide more frequent FDA interactions and potential eligibility for accelerated approval, priority review, and rolling review. The designation follows preliminary Phase 1 AURORAS-1 data in second-line or later KRAS G12X pancreatic ductal adenocarcinoma, where ERAS-0015 monotherapy at the 32 mg once-daily recommended dose for expansion showed a 57% uORR8wk, with all responding patients across doses remaining on treatment at the May 25, 2026 cutoff and a favorable tolerability profile. Erasca plans three potentially registration-enabling trials across pancreatic and lung cancers and expects additional monotherapy and combination data, including with panitumumab, in the first half of 2027.
Erasca (Nasdaq: ERAS) reported second quarter 2026 business updates highlighting ERAS-0015 and ERAS-4001 pipeline progress alongside a significantly strengthened balance sheet.

Erasca (Nasdaq: ERAS) reported updated preliminary Phase 1 AURORAS-1 data for pan-RAS molecular glue ERAS-0015 in RAS-mutant solid tumors and outlined potentially registration-enabling plans in lung and pancreatic cancers.
At the recommended dose for expansion (RDE) of 32 mg QD, ERAS-0015 monotherapy showed a 57% uORR at 8 weeks (N=7) in second-line or later KRAS G12X pancreatic ductal adenocarcinoma, with most enrolled patients remaining on treatment across 24 mg and 32 mg doses and a median relative dose intensity of 100% at both doses. Safety remained generally consistent with prior disclosures, with mostly low-grade treatment-related adverse events, no dose-limiting toxicities, low rates of dose interruptions or reductions due to TRAEs, and no discontinuations due to TRAEs.
In metastatic colorectal cancer, the first dose-escalation cohort combining ERAS-0015 16 mg with the approved commercial dose of panitumumab reported no DLTs in four DLT-evaluable patients, enabling cohort clearance and ongoing backfill and dose escalation. According to Erasca, additional monotherapy and combination data are expected in the first half of 2027. The company plans to initiate a potentially registration-enabling trial in 2L+ NSCLC in H1 2027, a Phase 3 pivotal trial in first-line pancreatic cancer in 2027, and a Phase 3 pivotal trial in RAS-mutant NSCLC between H2 2027 and H1 2028.
