- IMM20059, Immunome’s epsin 1 (EPN1)-specific antibody, binds to the surface of multiple tumor cell lines, including lung, breast and prostate cancers in preclinical testing -
- Combinatorial effect (> 50% reduction in tumor volume) was demonstrated with IMM20059 and anti-PD-L1 treatment atezolizumab -
EXTON, PA, USA I November 09, 2022 I 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 announced that it is presenting a poster at the Society for Immunotherapy of Cancer’s (SITC) 37th Annual Meeting in Boston, Massachusetts highlighting the Company’s preclinical data of IMM20059, a novel anti-epsin 1(EPN1) antibody.
“We continue to be pleased with the robust capabilities of our Discovery Engine to identify novel anti-tumor targets, including those that are abnormally (ectopically) expressed on tumor cells which have the potential to fundamentally shift treatment paradigms,” commented Purnanand Sarma, PhD, President and CEO of Immunome. “While further preclinical work will be required, we are quite encouraged by the results presented at SITC today. Treatment with the IMM20059 + atezolizumab combination resulted in over a 50% reduction in tumor volume (p
Lack of response and immunoresistance to checkpoint inhibitors is a well-known challenge in cancer treatment. While the epsin-1 protein is known to be upregulated in a variety of tumor types, it can also be ectopically expressed on the tumor cell surface, as demonstrated in Immunome’s poster, offering a new approach to cancer therapy. Insights into the role of epsin-1 as a potential target for cancer is evolving, but research by others1 also suggests targeting EPN1 has the potential to inhibt tumor growth. The findings presented by Immunome at SITC further suggest that combining an EPN1-targeting antibody, like IMM20059, with checkpoint inhibitor treatment could reactivate or increase immune response to the tumor.
