NEW YORK, May 15, 2023 /PRNewswire/ -- Elevation Oncology, Inc. (Nasdaq: ELEV), an innovative oncology company focused on the discovery and development of selective cancer therapies to treat patients across a range of solid tumors with significant unmet medical needs, today announced financial results for the quarter ended March 31, 2023, and highlighted recent business achievements.

"Throughout the first quarter of 2023, we made significant progress as a company. Most recently, we presented preclinical data for our lead candidate, EO-3021, demonstrating anti-tumor activity in preclinical models expressing varying levels of Claudin 18.2, and highlighted a clinical case study showing EO-3021 induced a confirmed partial response in a patient with metastatic gastric cancer," said Joseph Ferra, Interim Chief Executive Officer of Elevation Oncology. "This is an exciting time for us as we and our partner, CSPC Pharmaceutical Group Limited, embark on sharing initial clinical data from the ongoing Phase 1 study of EO-3021 at ASCO 2023. In addition, we remain on track to initiate our Phase 1 trial evaluating EO-3021 in the US in the second half of 2023."

Recent Business Achievements

EO-3021

• Presented preclinical proof-of-concept data at AACR 2023. Key preclinical findings included demonstrating anti-tumor activity in preclinical xenograft models of pancreatic and gastric cancers expressing varying levels of Claudin 18.2. A single-dose of EO-3021 demonstrated tumor regression across low, medium, and high Claudin 18.2-expressing models, with a lower minimal efficacious dose in models with medium and high levels of Claudin 18.2 relative to models with low levels of Claudin 18.2. EO-3021 also outperformed standard of care chemotherapy in gastric and pancreatic cancer preclinical xenograft models.
  
  
• Highlighted clinical case study of EO-3021 at AACR 2023. A clinical case study of a patient with metastatic gastric cancer in an ongoing Phase 1 clinical trial of SYSA1801 (EO-3021) in China (NCT05009966) conducted by CSPC Pharmaceutical Group Limited (HKEX: 01093) was also highlighted. The patient was treated with dose level 2, or 1.0mg/kg EO-3021, intravenously, every three weeks (treatment ongoing). The best overall response, as evaluated per RECIST v1.1, was a confirmed partial response (66.7% maximal tumor reduction), while the duration of response was approximately 11 months and ongoing.
  
  
• SYSA1801 (EO-3021) Phase 1 data selected for presentation at ASCO 2023. An abstract featuring SYSA1801 (EO-3021) Phase 1 clinical data has been selected for a poster presentation and poster discussion at the upcoming American Society of Clinical Oncology (ASCO) 2023 Annual Meeting, being held June 2-6, 2023, in Chicago, IL. The ongoing Phase 1 dose escalation and dose expansion study is evaluating SYSA1801 in patients with Claudin 18.2-positive advanced solid tumors and is being conducted in China by Elevation Oncology's partner, CSPC Pharmaceutical Group Limited (CSPC; HKEX: 01093).

Other Pipeline Programs

• Continue research and development efforts to advance novel therapeutic drug candidates and targets. Additional pipeline programs include those through its existing partnership with Caris Life Sciences.

Expected Upcoming Milestones and Operational Objectives

• Initiate Phase 1 clinical trial of EO-3021 in the US in the second half of 2023
• Ongoing target evaluation for future pipeline expansion

First Quarter 2023 Financial Results

As of March 31, 2022, the Company had cash, cash equivalents and marketable securities totaling $73.9 million, compared to $90.3 million as of December 31, 2022.

Research and development expenses for the first quarter 2023 were $7.3 million, compared to $13.6 million for the first quarter 2022. The decrease in R&D expense in the first quarter of 2023 was primarily related to the decrease in costs related to manufacturing clinical supply of seribantumab for use in the CRESTONE clinical trial. The Company prioritized its pipeline and realigned resources to advance its EO-3021 product candidate.

General and administrative expenses for the first quarter 2023 were $4.3 million, compared to $3.8 million for the first quarter 2022. The increase in G&A expense in the first quarter of 2023 was primarily related to increases in personnel costs, professional services and other administrative costs.

Restructuring charges were $5.1 million for the first quarter 2023, and consisted primarily of one-time charges related to the pipeline prioritization and realignment of resources to advance our EO-3021 product candidate, including $1.6 million of termination and contractual termination benefits for severance, healthcare and related benefits.

Net loss for the first quarter 2023 was $17.1 million, compared to $17.3 million for the first quarter 2022.

About EO-3021

EO-3021 (also known as SYSA1801) is a differentiated, clinical-stage antibody drug conjugate (ADC) comprised of an immunoglobulin G1 (IgG1) monoclonal antibody (mAb) that targets Claudin 18.2 and is site-specifically conjugated to the monomethyl auristatin E (MMAE) payload via a cleavable linker with a drug-to-antibody ratio (DAR) of 2. Claudin 18.2 is a specific isoform of Claudin 18 that is only expressed in gastric epithelial cells. During malignant transformation of gastric cancer, the tight junctions may become disrupted, exposing Claudin 18.2 and allowing them to be accessible by Claudin 18.2 targeting agents. Claudin 18.2 can also be expressed in other solids tumors. An Investigational New Drug application for EO-3021 has been cleared by the U.S. Food and Drug Administration.

About Elevation Oncology, Inc.

Elevation Oncology is an innovative oncology company focused on the discovery and development of selective cancer therapies to treat patients across a range of solid tumors with significant unmet medical needs. We are rethinking drug development by seeking out innovative, selective cancer therapies that can be matched to a patient's unique tumor characteristics. Our lead candidate, EO-3021, is a potential best-in-class antibody drug conjugate (ADC) designed to target Claudin 18.2, a clinically validated molecular target. EO-3021 selectively delivers a cytotoxic payload directly to cancer cells expressing Claudin 18.2. We are working to rapidly advance EO-3021 into the clinic in the US across a range of solid tumor indications, as well as exploring other opportunities through new or existing partnerships and business development opportunities to expand our novel oncology pipeline.
