- Trial Data Release: Erasca (ERAS) released early data from its Phase 1 trial for the solid tumor candidate ERAS-0015, resulting in a ~37% drop in stock price during after-hours trading, indicating market concerns about its clinical prospects.
- Safety Concerns: While ERAS-0015 demonstrated a well-tolerated safety profile in trials in the U.S. and China, the company disclosed a fatality of a heavily pre-treated pancreatic cancer patient who died after receiving a 24 mg dose, highlighting potential safety risks.
- Efficacy Data: The biotech reported unconfirmed overall response rates (uORR) of 62% and 40% among patients with KRAS G12X non-small cell lung cancer and pancreatic cancer, respectively, based on patients receiving 16-32 mg QD, suggesting some efficacy potential.
- Patent Dispute: Erasca revealed a potential patent dispute with rival Revolution Medicines (RVMD), which alleged that ERAS-0015 infringed its U.S. Patent No. 12,409,225, while Erasca stated it intends to contest these claims vigorously, demonstrating its strong stance on intellectual property.

About ERAS
Erasca, Inc. is a clinical-stage precision oncology company. The Company is focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers. The Company has assembled RAS/MAPK pathway-focused pipeline in the industry, consisting of modality-agnostic programs aligned with its three therapeutic strategies of: targeting key upstream and downstream signaling nodes in the RAS/MAPK pathway; targeting RAS directly; and targeting escape routes that emerge in response to treatment. Its pipeline includes one clinical-stage program (a pan-RAF inhibitor), two IND-enabling stage programs (a pan-RAS molecular glue and a pan-KRAS inhibitor), and an additional discovery-stage program (an EGFR D2/D3 biparatopic antibody). Its lead product candidate is naporafenib, the Company initiated its SEACRAFT-2 pivotal Phase III trial for patients with NRAS-mutated (NRASm) melanoma.

Erasca Announces Preliminary Phase 1 Data for ERAS-0015
- Clinical Trial Progress: Erasca's preliminary dose escalation data for ERAS-0015 in the AURORAS-1 trial shows confirmed and unconfirmed partial responses in multiple tumor types at a low dose of 8 mg once daily, indicating favorable safety and tolerability.
- Drug Characteristics: ERAS-0015 is an oral, highly potent pan-RAS molecular glue designed to inhibit RAS signaling with a potential best-in-class profile, capable of preventing resistance against mutant-selective inhibitors, thereby enhancing therapeutic efficacy.
- Conference Arrangement: Erasca will host a conference call and webcast on April 27, 2026, at 4:30 PM ET to discuss preliminary data for ERAS-0015, with investors able to access the live link through the company's website.

Erasca's Cancer Therapy Trial Reports Treatment-Related Death
- Treatment-Related Death: In Erasca's ERAS-0015 clinical trial, a 66-year-old pancreatic cancer patient developed Grade 3 pneumonitis after receiving a 24 mg dose, leading to death, which was buried in safety disclosures and caused the company's stock to plunge nearly 40% in after-hours trading.
- Early Tumor Response Rates: Despite the death, Erasca reported a 62% tumor response rate for ERAS-0015 in KRAS-mutant non-small cell lung cancer patients, rising to 75% among those previously treated with immunotherapy and platinum chemotherapy, indicating the therapy's potential efficacy.
- Future Data Expectations: Erasca anticipates additional data from the Auroras-1 trial in 2027, while preliminary data for its other candidate, ERAS-4001, is expected later this year, which could significantly impact the company's strategic direction and investor confidence.
