Tevogen Bio Holdings Inc. has announced a significant clinical milestone in the development of its investigational precision T cell therapy, TVGN 489, designed for the treatment of acute and Long COVID. The company has completed T cell target identification for an additional five human leukocyte antigen (HLA) restrictions, broadening patient eligibility for its therapy. This advancement builds on a previously completed clinical trial of TVGN 489, which demonstrated 100% viral clearance, no reinfections, and no cases of Long COVID in high-risk patients. Results from this initial proof-of-concept trial were published in Blood Advances. TVGN 489 utilizes off-the-shelf, genetically unmodified allogeneic T cells and aims to expand therapeutic access regardless of patients' genetic backgrounds.
