Brief Summary:
This study is an interventional, single arm, open-label, investigator-initiated trial (IIT) to evaluate the safety, tolerability, initial efficacy and pharmacokinetics (PK) of anti-5T4 CAR-NK cells in patients with advanced solid tumors.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Biological: Anti-CAR-NK Cells Early Phase 1

Detailed Description:
The treatment cycle in this study is 21 days. The administration of CAR-NK cell will be performed on day 1 and day 3 of each cycle. Subjects will be treated continuously until the criteria for termination of treatment are met. In this study, the dose escalation design is adopted. The first administration dose in the first cycle is 3.0×10^9 cells. If no adverse events were observed, the second administration dose in the first cycle would be 4.0×10^9 cells, and each administration dose in the second cycle and thereafter would be 4.0×10^9 cells.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Adverse Events (AEs) [ Time Frame: From day 1 to day 90 after the last dose ]
    To evaluate the safety and tolerability of anti-5T4 CAR-NK cells


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: Up to 1 year after infusion ]
    To determine the anti-tumor effectivity of anti-5T4 CAR-NK cells

  2. Progression-free survival (PFS) [ Time Frame: Up to 1 year after infusion ]
    To determine the anti-tumor effectivity of anti-5T4 CAR-NK cells

  3. Overall survival (OS) [ Time Frame: Up to 1 year after infusion ]
    To determine the anti-tumor effectivity of anti-5T4 CAR-NK cells

  4. Disease control rate (DCR) [ Time Frame: Up to 1 year after infusion ]
    To determine the anti-tumor effectivity of anti-5T4 CAR-NK cells

  5. Cytokine release [ Time Frame: Up to 1 year ]
    Blood samples will be collected at specified time points to detect the cytokine (IL-1β, IL-2, IL-4, IL-6, IL-10, IFN-γ, hsCRP) concentration (pg/mL)

  6. Lymphocyte subtype [ Time Frame: Up to 1 year ]
    Blood samples will be collected at specified time points to analyze the lymphocyte subtypes (CD3, CD4, CD8, CD19, CD56)

  3. Patients with advanced malignant solid tumors, histologically or cytologically confirmed, who had failed standard therapy, or had no standard therapy, or were not eligible for standard therapy at this stage; tumor biomarkers combined with imaging can be used to diagnose some special advanced tumors.
  4. Eastern Cooperative Oncology Group (ECOG) score ≤2 and expected survival time >3 months.

  5. Organ function during screening should meet the following criteria:

    • Absolute neutrophil count (ANC)≥0.8×109/L

    • Total bilirubin (TBIL)≤2×ULN
    • Alanine aminotransferase (ALT)≤3×ULN; Patients with liver metastasis or liver cancer: ≤5×ULN
    • Aspartate aminotransferase (AST)≤3×ULN; Patients with liver metastasis or liver cancer: ≤5×ULN
    • Creatinine (Cr)≤1.5× ULN
    • Creatinine clearance (Ccr) (to be calculated only when Cr > 1.5× ULN)>50ml/min/1.73m2 (Cockcroft-Gault formula)
    • Activated partial thrombin time (APTT)≤1.5×ULN

Except in the following cases: type 1 diabetes that was well controlled with hormone replacement therapy, hypothyroidism, skin conditions that did not require systemic therapy (e.g., vitiligo), and other conditions that were well controlled and that the investigator determined were less likely to recur (e.g., childhood asthma in remission).

  8. Have a history of serious cardiovascular and cerebrovascular diseases, including but not limited to:

    • There are serious cardiac rhythm or conduction abnormalities, such as ventricular arrhythmia, and Ⅱ-Ⅲ degree atrioventricular block, which need clinical intervention;
    • The mean QT interval corrected by Fridericia method (QTcF) is prolonged (male>450ms, female>470ms);
    • Acute coronary syndrome, congestive heart failure, aortic dissection, stroke, or other grade 3 or above cardiovascular and cerebrovascular events occurring within 6 months before the first administration;

    • Hypertension beyond clinical control.
  9. Adverse effects of previous antineoplastic therapy have not returned to CTCAE grade 5.0≤2 (except for toxicity that the investigator determined to be of no safety risk, such as alopecia, hypothyroidism stabilized by hormone replacement therapy).
  10. Central nervous system metastases with clinical symptoms.
  11. Had other malignant tumors in the past 3 years, excluding skin basal cell carcinoma, ductal carcinoma in situ and cervical carcinoma in situ with a radical surgery.
  12. Have a history of alcohol or drug abuse or mental disorder.
  13. The investigator considered that the subjects had a history of other serious systemic diseases or other reasons that made them unsuitable for the study.
