Colorectal Cancer (Locally Advanced or Metastatic)

This clinical trial evaluates the efficacy and safety of adding fecal microbiota transplantation (FMT) to first-line standard of care for patients with initially unresectable colorectal cancer (CRC). FMT is an established procedure designed to restore intestinal microbiome homeostasis by transferring processed fecal microbiota from a rigorously screened healthy donor into the patient's gastrointestinal tract. The standard first-line treatment regimen typically consists of chemotherapy, with or without targeted therapy. Approximately 220 patients across 13 participating centers will be randomly assigned to receive either standard therapy alone or standard therapy combined with FMT. The primary endpoint is the objective response rate (ORR). Secondary endpoints include the conversion to resectability rate, progression-free survival (PFS), safety and adverse events, quality of life (QoL), anxiety and depression scales, as well as dynamic changes in the gut microbiome and circulating biomarkers. The ultimate goal of this trial is to determine whether microbiome modulation via FMT can synergistically enhance the antitumor efficacy of standard first-line therapies and mitigate treatment-related toxicities in this patient population.

To evaluate the efficacy and safety of immune checkpoint inhibitor-based combination therapy with targeted therapy and chemotherapy in patients with locally advanced unresectable or metastatic colorectal cancer.

This Phase 1/2 study evaluates the safety, feasibility, and preliminary anti-tumor activity of allogeneic donor-derived CAR-NK cells in participants with advanced solid tumors. The CAR target antigen is selected for each participant after tumor profiling using a tissue biopsy and/or liquid biopsy. Participants will receive either a single-target or dual-target CAR-NK product based on the antigen profile.

The autologous immune cell induction technology used in this project involves transforming peripheral blood mononuclear cells (PBMC) into autologous DC cells, NK cells, CIK cells and other immune cells through cytokine induction, and then re-administering them to the patients. This therapy utilizes biotechnology to culture the immune cells of cancer patients in vitro and then re-infuse them back into the body, stimulating and enhancing the body's own immune function, killing and inhibiting cancer cells, eliminating small and residual lesions, or achieving the goal of treating cancer by significantly inhibiting the proliferation of residual cancer cells.
