Affini-T Therapeutics, Inc., a precision immunotherapy company unlocking the power of T cells against oncogenic driver mutations, today announced that preclinical data from its oncogenic driver programs targeting HLA-A*11:01 KRAS G12D and HLA-A*02:01 p53 R175H will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2024 held in San Diego, CA. In addition, two trial-in-progress posters for Affini-T's Phase 1 clinical-stage programs targeting KRAS G12V, the company-sponsored AFNT-211 study and the Fred Hutchinson Cancer Center investigator-initiated AFNT-111 study, will be presented at the same conference.

Poster presentation details are as follows:

Title: Non-viral engineered T cell therapy specific for the hotspot mutation p53 R175H that integrates signal 1 (TCR), signal 2 (co-stimulation) and signal 3 (cytokine) and co-opts FasL-dependent apoptosis to achieve a coordinated antitumor CD4/8 T cell response
