Erasca Reports Fourth Quarter 2021 Financial Results and Business Updates

Five ongoing clinical trials evaluating candidates ERAS-007 (ERKi), ERAS-601 (SHP2i), and ERAS-801 (CNS-penetrant EGFRi)

Initial Phase 1b data for HERKULES-1 and Phase 1 data for FLAGSHP-1 expected in H2 2022

Robust balance sheet with cash of $459 million

SAN DIEGO, March 24, 2022 (GLOBE NEWSWIRE) -- Erasca, Inc. (Nasdaq: ERAS), a clinical-stage precision oncology company singularly focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers, today reported financial results for the fiscal quarter ended December 31, 2021, and provided business updates.

“Erasca capped off a productive year by achieving all of our 2021 clinical and corporate milestones on or ahead of schedule,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “We initiated three HERKULES clinical trials in 2021 evaluating our ERK1/2 inhibitor ERAS-007 across tissue agnostic and tissue specific indications. We announced earlier this month that we entered into a clinical trial collaboration and supply agreement (CTCSA) with Lilly for the EGFR antibody cetuximab, which complements our previously announced CTCSA with Pfizer for the BRAF inhibitor encorafenib. ERAS-007 is being added to the standard of care regimen of encorafenib plus cetuximab in patients with BRAF V600E-mutant metastatic colorectal cancer as part of our ongoing HERKULES-3 trial, and we are excited about these agreements with Pfizer and Lilly. We will expand the evaluation of ERAS-007 into blood cancers with HERKULES-4, a master protocol for the treatment of patients with hematological malignancies with initial focus in acute myeloid leukemia (AML).”

Dr. Lim continued, “Our CNS-penetrant product candidates continued to advance well in 2021. First, in June 2021, we nominated ERAS-3490, a highly CNS-penetrant KRAS G12C inhibitor and our first homegrown development candidate. This molecule was specifically designed to cross the blood-brain barrier to address the propensity of non-small cell lung cancer to metastasize to the brain, and we are currently on track for an IND filing in the second half of 2022. Second, we were pleased to receive IND clearance of ERAS-801 for the treatment of patients with recurrent glioblastoma multiforme a quarter earlier than expected, and we dosed the first patient in THUNDERBBOLT-1 last month. ERAS-801 is an oral EGFR inhibitor with four times higher CNS penetration than approved EGFR inhibitors and the differentiated ability to target both oncogenic EGFR vIII mutations and wildtype alterations. Overall, our solid cash position, industry leading portfolio, and focused approach will enable us to continue to execute well in 2022.”

Research and Development (R&D) Highlights

• Presented Preclinical Data for ERAS-801: In October 2021, Erasca announced the presentation of preclinical data for ERAS-801, a central nervous system (CNS)-penetrant epidermal growth factor receptor (EGFR) inhibitor for the treatment of recurrent glioblastoma multiforme (GBM), at the American Association for Cancer Research (AACR) Conference on Brain Cancer
• Received FDA Clearance of IND Application for ERAS-801 in Recurrent Glioblastoma Multiforme: In December 2021, the United States Food and Drug Administration (FDA) cleared an investigational new drug (IND) application for ERAS-801
• Dosed First Patient in THUNDERBBOLT-1 Trial: In February 2022, Erasca dosed the first patient in THUNDERBBOLT-1, a Phase 1 trial evaluating ERAS-801 for the treatment of recurrent GBM
• Announced Six Poster Presentations at the 2022 AACR Annual Meeting: In March 2022, Erasca announced six poster presentations, featuring programs with best-in-class potential, including ERK1/2 inhibitor ERAS-007, SHP2 inhibitor ERAS-601, and CNS-penetrant KRAS G12C inhibitor ERAS-3490. Erasca will be hosting an investor webinar on Tuesday, April 12, 2022, highlighting its 2022 AACR presentations and featuring a presentation by key opinion leader Scott Kopetz, M.D., Ph.D., of MD Anderson Cancer Center

• Strengthened Executive Leadership: In January 2022, Erasca appointed Lisa Tesvich-Bonora, Ph.D., as Chief People Officer and promoted Robert Shoemaker, Ph.D., to Senior Vice President of Research
• Entered into a Clinical Trial Collaboration and Supply Agreement with Lilly: Under this agreement, which Erasca announced in March 2022, Lilly will supply its EGFR inhibitor cetuximab (ERBITUX^®) at no cost in connection with a clinical proof-of-concept study evaluating ERAS-007 in combination with the BRAF inhibitor encorafenib and cetuximab for the treatment of patients with BRAF V600E-mutant metastatic colorectal cancer (CRC) as part of the ongoing Phase 1b/2 HERKULES-3 trial. This CTCSA complements the previously signed CTCSA with Pfizer for the BRAF inhibitor encorafenib (BRAFTOVI^®)
