PHASE1/PHASE2

Biological Tumor Infiltrating Lymphocytes Therapy With Immunotherapy for Colon and Rectum Cancer

Sponsor: Essen Biotech

View on ClinicalTrials.gov

Summary

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.
