Prevention of Postoperative Recurrence of Hepatocellular Carcinoma by Blocking RAK Cells With Anti-TIM-3

Обзор

To compare the safety and efficacy of unmodified RAK cells and anti-TIM-3 blocked autologous RAK cells in preventing postoperative recurrence of HCC by postoperative TACE therapy combined with immune cell therapy.

Подробное описание

Research process:

Initial screening period (-7 to -1 days)

• Sign an informed consent form;

• Assign screening numbers;

• Assessment of eligibility for initial screening.

1. Day 0 (period 1)

* Reconfirm the inclusion and exclusion criteria; * 50-60ml of anticoagulant peripheral blood was sampled;

Treatment time: 2. On (±2) days 15 and 16, Autologous RAK cells were reinfused for treatment (cycle 1). 3. TACE was performed on day 28 (±7). 4. Blood drawing from autologous RAK cells in the second cycle (week 10 ±7 days) 5. The second cycle of autologous RAK cell transfusion treatment (12 weeks ±7 days after hepatocellular carcinoma surgery); 6. Blood was drawn from autologous RAK cells in the third cycle (week 22 ±7 days); 7. Reinfusion of autologous RAK cells in the third cycle (week 24 ±7 days);

After completing 3 cycles of treatment, the patients were assessed by the investigator to be under control or remission of disease after treatment, and then they were followed up for treatment
