Open-label, phase 1, multicenter study to evaluate the safety and preliminary anti-tumor activity of NT-175 in human leukocyte antigen-a*02:01

The TP53 tumor suppressor gene is the most commonly mutated gene across all cancer types, and TP53 R175H is the most common recurrent mutation across indications, identified in 6.7% of patients with breast cancer, 6% of patients withs colorectal cancer, and 4.2% of patients with pancreatic cancer. No therapy is approved for treatment directly targeting TP53 R175H. NT-175 is an armored autologous T-cell product expressing an HLA-A*02:01-restricted TCR recognizing TP53 R175H with disruption of the endogenous TCR and the transforming growth factor beta receptor type 2 (TGFBR2) genes.
