TCR-T Therapy Development Service for Pancreatic Cancer

TCR-T Therapy Development Service for Pancreatic Cancer

T-cell receptor (TCR-T) therapy, which involves the utilization of TCRs that bind to human leukocyte antigens (HLA) and whose target range can be greatly expanded to include cytoplasmic and nuclear proteins, is a promising option for the treatment of pancreatic cancer. Alfa Cytology aims to utilize decades of experience and deep expertise in TCR biology to expand the potential of cellular therapies.

Overview of TCR-T Cell Therapy for Pancreatic Cancer

TCR-T therapies use heterodimers composed of α and β peptide chains to recognize peptide fragment molecules presented by MHC. Unlike chimeric antigen receptor (CAR) T-cell therapies that target surface antigens, TCR-T cells recognize intracellular antigens processed and presented by MHC molecules. This expands the range of antigens that can be targeted and allows for the targeting of cancer-specific mutations or neoantigens. Recently, researchers found that using a single infusion of genetically modified autologous T cells could target the mutated KRAS G12D HLA-C binding epitope and treated a patient with progressive metastatic PDAC.

In addition, several preclinical studies have explored the efficacy of TCR-T cell therapy in pancreatic cancer. Notable advances include:

  • Targeting Mutant KRAS: TCR-T cells designed to target the KRAS G12D and G12V mutations have been observed to enhance tumor regression in mouse models.
  • MUC1 as a Target Antigen: MUC1-specific TCR-T cells were able to recognize and kill pancreatic tumor cells, thereby prolonging survival in animal models.
