Autologous Tumor-Infiltrating Lymphocytes(Essen Biotech)

This Phase I/II study evaluates the safety and efficacy of autologous tumor-infiltrating lymphocytes (TIL) therapy combined with Pembrolizumab (Keytruda) and Aldesleukin (interleukin-2, IL-2) immunotherapy in patients with advanced or metastatic refractory colon and rectal cancer (colorectum). TILs will be harvested from patients' tumors, expanded in vitro, and infused back into the patients following a non-myeloablative lymphodepletion regimen. Pembrolizumab, a monoclonal antibody targeting the PD-1 receptor on T cells, will be administered to enhance the immune response, while Aldesleukin will be used to further stimulate the TILs. The primary endpoint is to determine the objective response rate (ORR) of this combined therapy. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), and quality of life (QoL). This trial aims to provide a novel, personalized treatment option for patients with limited therapeutic alternatives.

This Phase I/II study evaluates the safety and efficacy of autologous tumor-infiltrating lymphocytes (TIL) therapy combined with Pembrolizumab (Keytruda) immunotherapy in patients with advanced or metastatic refractory stomach and esophageal cancer. Lifileucel (Amtagvi), the first FDA-approved TIL therapy, has shown significant promise in treating unresectable or metastatic melanoma by leveraging the patient's own immune cells to target and destroy cancer cells. This study aims to apply a similar approach to stomach and esophageal cancers. TILs will be harvested from patients' tumors, expanded in vitro, and infused back into the patients following a non-myeloablative lymphodepletion regimen. Pembrolizumab, a monoclonal antibody that targets the PD-1 receptor on T cells, will be administered to enhance the immune response. The primary endpoint is to determine the objective response rate (ORR) of this combined therapy. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), and quality of life (QoL).
