Elevation Oncology Shifts Focus from EO-3021 to EO-1022 Following Development Update

Elevation Oncology's Strategic Shift: EO-3021 Discontinuation and EO-1022 Advancement

Elevation Oncology, a pioneering company in the oncology sector, recently announced a significant change in its developmental focus. The firm has made the strategic decision to discontinue the development of EO-3021, an antibody-drug conjugate aimed at treating advanced gastric and gastroesophageal junction (GEJ) cancers. Instead, the company will bolster its efforts on EO-1022, another promising candidate in its portfolio.

Clinical Background on EO-3021

EO-3021 was designed to target Claudin 18.2, a biomarker frequently associated with gastric and GEJ cancers. Despite initial hopes, the results from Phase 1 clinical trials indicated that EO-3021's performance fell short of expectations. The objective response rate (ORR) was only 22.2%, a figure that the company’s president, Joseph Ferra, acknowledged as insufficient to sustain the drug’s clinical development.

Key findings from the clinical trial showed that out of 36 evaluable patients, the drug produced one complete response and seven partial responses, leading to the conclusion that EO-3021 did not present any competitive advantage over existing treatments for Claudin 18.2 positive cancers. The adverse event profile also raised concerns, albeit showing minimal toxicity overall, it wasn't sufficient to warrant continued investment in EO-3021.

Ferra expressed his disappointment, stating, "We are deeply disappointed by these results. Despite demonstrating safety as a more combinable ADC, the updated efficacy data do not meet our threshold for success." He also extended his gratitude to all stakeholders involved in the trials, clarifying the company’s commitment to transitioning away from EO-3021.

Advancing EO-1022

In place of EO-3021, Elevation Oncology is focusing on EO-1022, a HER3 antibody-drug conjugate designed to treat patients with HER3-expressing solid tumors. The therapeutic agent utilizes an MMAE payload combined with glycan site-specific conjugation, which the company believes presents a differentiated approach in its treatment strategy.

Looking ahead, the company plans to present preclinical data for EO-1022 at the upcoming AACR Annual Meeting 2025, with an Investigational New Drug (IND) application targeted for 2026. Ferra emphasized the need for this strategic pivot to address unmet medical needs in the field of oncology, indicating a commitment to ensuring the ongoing development of EO-1022.

Corporate Restructuring

As part of this strategic shift, Elevation Oncology has also announced a significant workforce reduction of approximately 70%. This decision has been driven by the need to streamline operations and reallocate resources towards developing EO-1022. The anticipated costs linked to this restructuring are estimated to total around $3 million, focusing on ensuring that the majority of these expenses are settled by June 2025.

Additionally, Valerie Malyvanh Jansen, the Chief Medical Officer, will be stepping down at the end of March 2025 but will continue to provide consultancy support to the organization. Ferra spoke highly of the team’s dedication over the past five years, acknowledging their tireless efforts in advancing cancer treatment pathways through innovative solutions.

Financial Prospects

Despite the setbacks with EO-3021, the company reports a robust financial position, with approximately $93.2 million available as of December 31, 2024, expected to sustain operations into the second half of 2026. Elevation Oncology remains committed to maximizing shareholder value as it navigates through this transitional period, ensuring that strategic options are methodically evaluated.

In summary, while the discontinuation of EO-3021 is a notable setback for Elevation Oncology, the firm is resolutely pivoting its focus to EO-1022, positioning itself to potentially deliver ground-breaking therapies for patients suffering from HER3-expressing cancers. The landscape of cancer treatment continues to evolve, and Elevation Oncology aims to remain at the forefront of this transformation.
