Summary

The USPTO has published a patent application (US20260085105A1) filed by Amgen Inc. for recombinant T-cell receptors designed to selectively recognize MAGE-A4-derived peptides. The application details screening for cross-reactivity and alloreactivity.

What changed

This document is a publication of a US patent application (US20260085105A1) filed by Amgen Inc. The application describes recombinant T-cell receptors (TCRs) engineered to recognize specific MAGE-A4-derived peptides when presented by HLA-A*0201, with the aim of activating recombinant T cells. The inventors have screened these TCRs for cross-reactivity with similar peptides found in normal cells and for alloreactivity.

As this is a patent application, it does not impose immediate regulatory obligations or compliance deadlines on entities. However, it signifies potential future intellectual property and product development in the field of cancer immunotherapy. Companies operating in the pharmaceutical and biotechnology sectors, particularly those involved in T-cell therapy or cancer treatment, should be aware of this filing as it may impact their research and development strategies or patent landscape.

Inventors

Sungeun KIM, Matthew James RARDIN

Abstract

Provided herein are recombinant T-cell receptors (TCRs) that can selectively recognize the MAGE-A4-derived peptide GVYDGEEHSV or KVEEHVVRV when presented by HLA-A*0201 sufficiently to activate the recombinant T cell. TCRs provided herein were thoroughly screened for lack of cross-reactivity with similar peptides that may be presented by normal cells or tissue and for alloreactivity.
