  • Significant progress across all clinical programs including Phase 1b combo data for ERAS-007 and ERAS-601, FTD and ODD granted for ERAS-801, and publication of naporafenib combination data
  • Multiple meaningful clinical catalysts over the next 18 months and beyond
  • Strong balance sheet with cash, cash equivalents, and marketable securities of $365 million as of June 30, 2023, expected to fund operations into H2 2025

SAN DIEGO, Aug. 10, 2023 (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 June 30, 2023, and provided business updates.

“Our team continues to achieve important milestones for our four clinical programs that underscore their potential to address unmet needs for multiple patient segments affected by oncogenic RAS/MAPK pathway signaling,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “Expansion of ERAS-007 plus encorafenib and cetuximab (EC) in patients with EC-naïve BRAF-mutated (BRAFm) colorectal cancer (CRC) is advancing following the encouraging early efficacy data seen in HERKULES-3 [50% (3/6) response rate (2 cPR, 1 uPR) at the highest dose tested]. We are also building on the encouraging initial Phase 1b dose escalation data for ERAS-601 plus cetuximab in FLAGSHP-1, with Phase 1b combination dose expansion data planned for the first half of 2024.”

Dr. Lim continued, “Importantly, we remain on track to dose the first patient in the SEACRAFT-1 Phase 1b trial in RAS Q61X solid tumors for our most advanced program, the potential first-in-class and best-in-class pan-RAF inhibitor naporafenib. Finally, we are continuing to advance our CNS-penetrant EGFR inhibitor ERAS-801, which was granted FDA Fast Track and Orphan Drug Designations, in recurrent glioblastoma (GBM). Our balance sheet continues to be strong, supporting a cash runway into the second half of 2025 and through the execution of meaningful clinical catalysts over the next 18 months.”

Research and Development (R&D) Highlights

  • Presented Promising HERKULES-3 Phase 1b Data and Refined Pipeline: In June 2023, Erasca presented preliminary Phase 1b data for ERAS-007 in combination with encorafenib + cetuximab (EC) in patients with BRAFm CRC, showing a 50% (3/6) response rate (2 confirmed partial responses, 1 unconfirmed partial response), reinforcing ERAS-007 as a potential best-in-class ERK inhibitor. In addition, a strategic pipeline prioritization sharpened Erasca’s focus on existing programs with the highest probability of success.
  • Granted FDA Orphan Drug and Fast Track Designations for ERAS-801: In June 2023, Erasca announced that the United States Food and Drug Administration (FDA) granted Orphan Drug Designation (ODD) to ERAS-801 (CNS-penetrant EGFR inhibitor) for the treatment of malignant glioma, which includes GBM. In May 2023, Erasca announced that the FDA granted Fast Track Designation (FTD) to ERAS-801 for the treatment of adult patients with GBM with EGFR gene alterations.
  • Presented Promising FLAGSHP-1 Phase 1b Data: In April 2023, Erasca presented promising data for ERAS-601 (SHP2 inhibitor) in combination with cetuximab in patients with advanced solid tumors as part of a poster presentation at the American Association for Cancer Research (AACR) Annual Meeting.
  • Announced Publication of Phase 1b Data for Naporafenib: In April 2023, Erasca announced the publication of results in the Journal of Clinical Oncology from the expansion arm of a Phase 1b open label trial evaluating pan-RAF inhibitor naporafenib plus MEK inhibitor trametinib (MEKINIST®) in patients with NRASm melanoma. This potential will be further explored in our SEACRAFT-2 pivotal Phase 3 trial.

Corporate Highlights

  • Appointed Lead Independent Director: In July 2023, James Bristol, Ph.D., was appointed to the position of lead independent director. In addition to this role, Dr. Bristol shall continue to serve on the board’s compensation committee and nominating and corporate governance committee.
  • Strengthened Business Leadership: In May 2023, Erasca promoted David Chacko, M.D., previously Erasca’s chief financial officer, to the dual position of chief financial officer and chief business officer, and Nik Chetwyn, Ph.D., previously Erasca’s senior vice president of operations, to chief operating officer.

Second Quarter 2023 Financial Results

Cash Position: Cash, cash equivalents, and marketable securities were $365.3 million as of June 30, 2023, compared to $435.6 million as of December 31, 2022. Erasca expects its current cash, cash equivalents, and marketable securities balance to fund operations into the second half of 2025.

Research and Development (R&D) Expenses: R&D expenses were $26.2 million for the quarter ended June 30, 2023, compared to $27.5 million for the quarter ended June 30, 2022. The decrease was primarily driven by decreases in expenses incurred in connection with clinical trials, preclinical studies, discovery activities and outsourced services and consulting fees, partially offset by increases in facilities-related expenses and depreciation, and personnel costs, including stock-based compensation.

General and Administrative (G&A) Expenses: G&A expenses were $9.8 million for the quarter ended June 30, 2023, compared to $8.4 million for the quarter ended June 30, 2022. The increase was primarily driven by personnel costs, including stock-based compensation expense.

Net Loss: Net loss was $31.8 million, or $(0.21) per basic and diluted share, for the quarter ended June 30, 2023, compared to $35.6 million, or $(0.30) per basic and diluted share, for the quarter ended June 30, 2022.
