Immunome Reports Third Quarter 2022 Financial Results

Immunome, Inc. (NASDAQ:IMNM), a clinical stage biopharmaceutical company that utilizes its human memory B cell platform to discover and develop first-in-class antibody therapeutics, today reported financial results for the third quarter ended September 30, 2022 and provided a corporate update.

"We look forward to completing our clinical trial for IMM-BCP-01, our COVID-19 antibody program, while continuing to expand our oncology portfolio including our planned submission of the IND for IMM-ONC-01 by mid-2023. Our Discovery Engine provides unique insights into how the human immune system sees disease and continues to highlight interesting areas of cancer biology and identify novel targets and corresponding antibodies."

Dr. Sarma continued, "In parallel with our oncology pre-clinical initiatives, we continue to monitor the evolution of multiple new variants of SARS-CoV-2, including BA.4.6, BQ.1, BQ.1.1 and BF.7, and expect to complete enrolment of our Phase 1b trial of IMM-BCP-01 by the end of the year. We also anticipate obtaining topline safety and PK data by the end of the year and look forward to announcing those results in the beginning of 2023."

Highlights

• Preclinical Data on Novel Anti-EPN1 Antibody IMM20059 at the Society for Immunotherapy of Cancer's (SITC) 37^th Annual Meeting. In November 2022, Immunome announced that it presented a poster presentation at the Society for Immunotherapy of Cancer's (SITC) 37^th Annual Meeting. Immunome's preclinical research of IMM20059 demonstrated that IMM20059, in the combination with the anti-PD-L1 atezolizumab, significant tumor regression was induced compared to IMM20059 or atezolizumab treatment alone, suggesting a potential combinatorial effect between the two anti-tumoral pathways.
• Publication in Clinical & Translational Immunology Highlighting B Cell Repertoires in Patients with Breast Cancer. In August 2022, Immunome announced the publication of a peer-reviewed article in Clinical & Translational Immunology characterizing B cell repertories in tissue samples from patients with breast cancer. The results published by Immunome and its collaborators, provide a framework for understanding how features of tumours relate to the potential for B cells to target cancer cells and these cancer specific B cells are disseminated across tumours, sentinel lymph nodes and blood in the same patient.
• IMM-BCP-01 Retains Neutralizing Activity Against Prevalent Omicron Subvariants, BA.4/.5 and BA.2.12.1. In July 2022, Immunome announced that its antibody cocktail retained activity against the BA.4/.5 and BA.2.12.1 subvariants in pseudovirus testing. Data recently published in the peer-reviewed journal Science Immunology provides a mechanistic basis for how IMM20253 binding, which is conserved across all variants to date including Omicron and its sub-lineages, neutralized SARS-CoV-2.

Financial Highlights

• Research and development (R&D) expenses: R&D expenses for the three months ended September 30, 2022, were $5.2 million.
• General and administrative (G&A) expenses: G&A expenses for the three months ended September 30, 2022, were $3.3 million.
• Net loss: Net loss for the three months ended 2022 was $8.5 million.
• Cash and cash equivalents: As of September 30, 2022, cash and cash equivalents totaled $27.1 million.

The investigational work for IMM-BCP-01 was funded by the U.S. Department of Defense's (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) in collaboration with the Defense Health Agency (DHA) (Contract number: W911QY-20-9-0019).
