Study Overview

IX001 TCR-T In the Treatment of Advanced Pancreatic Cancer and Colorectal Cancer Induced by KRAS Mutations

This is a single-arm, single-center, open-label clinical study aimed at evaluating the safety and efficacy of IX001 TCR-T (T cell receptor-engineered T-Cell) injection in patients with advanced pancreatic cancer and colorectal cancer induced by KRAS (Kirsten Rat Sarcoma Viral Oncogene) mutations. A total of 6-18 evaluable patients are planned to be enrolled. The study will include 4 dose groups, using a '3+3' dose escalation design.

Patients who sign the informed consent form will undergo screening based on inclusion/exclusion criteria. Eligible patients will be enrolled sequentially into dose group 1, dose group -1 or dose group 2, and dose group 3. The procedure of this study is as follows: (I) The collected peripheral blood mononuclear cells (PBMCs) will be transported to the production workshop for the preparation of IX001. After confirming that IX001 is proved qualified, the investigator will decide whether to start pre-conditioning 5 days before IX001 infusion. (II) TCR-T cells will be administered via intravenous infusion, and the cell infusion dose will be determined according to the requirements of dose escalation. (III) Following TCR-T cell infusion, recombinant human interleukin-2 (IL-2) will be continuously injected to assist TCR-T cell growth. (IV) After TCR-T cell infusion and IL-2 injection are completed, safety and efficacy follow-up visits will be conducted with the subjects until week 96 or until the subject prematurely withdraws from the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

    Inclusion Criteria:
    1. Voluntary signing of an informed consent form (ICF); 2. Males or females, aged 18-70 years (inclusive); 3. Pathologically diagnosed with advanced pancreatic cancer or colorectal cancer, having failed or intolerant to at least two lines of standard of care, including metastatic tumors (having received conventional chemotherapy), recurrent tumors (having undergone surgery and adjuvant chemotherapy in the past), or locally advanced tumors with disease progression after neoadjuvant treatment; 4. At least one measurable lesion (according to RECIST1.1[The Response Evaluation Criteria In Solid Tumors] criteria); 5. Patients with tumor tissue or peripheral blood testing positive for KRAS-G12V or G12D mutations and expression of matching HLA-A*11, C*01:02, or C*08:02 subtypes; 6.
