A Phase I/ II Study of Fragmented Autoantigen Stimulated T-cell-immunotherapy Combined with Radiotherapy (FAST-CR)

Korábbi kezelés

• Patients who do not have enough tumor resected or puncture tissue for vaccine production.
  • Patients who have failed third-line therapy, and whose tumor location or type is not suitable for radiotherapy (as evaluated by the expert group).
  • Patients whose tumor tissue preparation for the vaccine does not meet the efficacy assessment criteria before enrollment (individualized FAST vaccine Elispot test, see Appendix 4 for specific testing protocol).
  • Patients with a history of bone marrow or stem cell transplantation. Patients currently participating in other therapeutic clinical trials; Traditional Chinese medicine clinical trials.
  • Patients with active bacterial or fungal infections as per NCI-CTC (National Cancer Institute Common Terminology Criteria for Adverse Events) CTCAE 5.0.
  • Patients infected with HIV (Human Immunodeficiency Virus), HCV (Hepatitis C Virus), HBV (Hepatitis B Virus), severe asthma, autoimmune diseases, immunodeficiency, or those undergoing immunosuppressive therapy.
  • Patients with herpesvirus infection (except those whose lesions have scabbed for more than 4 weeks).
  • Patients with respiratory viral infections (except those who have been cured for more than 4 weeks).
  • Patients with severe coronary artery or cerebrovascular diseases, or other diseases that the investigator considers should be excluded.
  • Patients with clinical, psychological, or social factors that affect their ability to provide informed consent for the study.
  • Patients with a history of autoimmune diseases, such as but not limited to inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis, scleroderma, or multiple sclerosis. Patients with autoimmune-related thyroid diseases and vitiligo are allowed.
  • Patients with severe chronic or acute comorbidities, such as heart disease (NYHA Class III or IV), liver disease, or other diseases that the principal investigator considers to pose unnecessary high risk in relation to the study drug treatment.
  • Patients who have a second malignant tumor at the same time (or within the past 5 years), except for melanoma skin cancer, cervical carcinoma in situ, controlled superficial bladder cancer, or other treated carcinoma in situ.
  • Patients with active acute or chronic infections, including urinary tract infections, HIV (as confirmed by ELISA and Western Blot). HIV-infected individuals may be excluded because immunosuppression could prevent them from responding to the vaccine; chronic hepatitis patients may be excluded due to concerns that vaccination could exacerbate their hepatitis.
  • Patients with a history of drug or peptide allergies, or allergies to other potential immunotherapies.
  • Patients undergoing chronic steroid treatment (or other immunosuppressive agents, such as azathioprine or cyclosporine A) will be excluded due to potential immunosuppression. Patients must stop any steroid treatment 6 weeks prior to enrollment (except for drugs used for chemotherapy, contrast-enhanced imaging, or acute treatment of complications such as gout attacks <5 days).
  • Patients with acute or chronic skin diseases will be excluded, as these conditions could affect the injection into the skin of the limbs or the subsequent evaluation of potential skin reactions.
  • Patients without legal capacity.

• Voluntarily agree to participate in this study. Age: 18-80 years, regardless of gender. Pathological and imaging diagnosis of advanced or recurrent malignant tumors. The patient must have previously received systemic standard treatment that has failed or led to disease progression, with no effective first-line treatment options available for advanced tumors (effective treatment options refer to the latest clinical guidelines published by the "Chinese Society of Clinical Oncology"). Alternatively, the patient may have undergone standard surgical treatment for tumor relapse prevention.
  • At least one measurable lesion on imaging (excluding patients who have undergone surgical treatment).
  • Expected survival ≥ 6 months. ECOG (Eastern Cooperative Oncology Group) performance status score of 0-1. No infectious diseases: HIV antibody negative. Normal hematological function: White blood cells ≥ 3000 cells/µL, hemoglobin ≥ 9 g/dL, platelets ≥ 75,000 cells/µL, absolute neutrophil count > 1000 cells/mm³.
  • Normal renal function: Serum creatinine (Cr) ≤ ULN × 1.5. Normal liver function: Serum ALT/AST levels less than three times the upper limit of normal.
  • The patient must be willing to sign an informed consent form and able to comply with the treatment plan.
  • The patient must undergo tumor resection or biopsy (for vaccine preparation) and peripheral blood collection (for efficacy and prognosis evaluation).
