Clinical Trial Summary

This study is a phase II, prospective, single-center, single-arm trial to evaluate the efficacy and safety of the combination of neoadjuvant transcatheter arterial chemoembolization (TACE) and PD-1 antibody Tislelizumab in the locally advanced stomach adenocarcinoma. The primary purpose of this study is to evaluate the pathologic complete response (pCR) rate of TACE plus Tislelizumab. The second purpose is to evaluate pathologic response rate (pRR), objective Response Rate (ORR), overall survival (OS) and progression-free survival (PFS) of the patients enrolled in this study.

Description:

The treatment of advanced gastric cancer has been a significant global health problem. With surgery still the backbone, various clinical trials have shown the benefit of perioperative treatment to gastric cancer patients.

The report of transcatheter arterial chemoembolization (TACE) treatment in gastric cancer is relatively limited, though different case reports have showed its efficacy and safety in advanced gastric cancer. With transarterial infusion chemotherapy, TACE increases the local concentration of chemotherapeutic agents and reduces adverse reaction. With embolization, TACE blocks the blood supply and causes the necrosis of tumors, in this way exposing tumor antigen and promoting tumor immunity. The combination of TACE and PD-1 antibody is expected to further boost tumor immunity.

Meanwhile, Noman et.al. reported hypoxia could upregulate PD-L1 by activating HIF-1alpha. So, embolism may lead to immune evasion of tumors by upregulating PD-L1, but on the other side generate targets for PD-1/PD-L1 therapies.

Based on those knowledges, we designed this phase II, prospective, single-center, single-arm trial to evaluate the efficacy and safety of the combination of neoadjuvant transcatheter arterial chemoembolization (TACE) and PD-1 antibody Tislelizumab in the locally advanced stomach adenocarcinoma. The primary purpose of this study is to evaluate the pathologic complete response (pCR) rate of TACE plus Tislelizumab. The second purpose is to evaluate pathologic response rate (pRR), objective Response Rate (ORR), overall survival (OS) and PFS (progression-free survival) of the patients enrolled in this study.

22. Have received live vaccines within 4 weeks before enrollment. (Remarks: Seasonal flu vaccines are usually inactivated vaccines and are allowed to be used. Vaccines used in the nasal cavity are live vaccines and are not allowed.);

23. Have received immunotherapy (such as interleukin, interferon, thymosin, etc.) or any trial treatment within 28 days or 5 half-lives (whichever is shorter, but at least 14 days) before enrollment;

24. Palliative radiotherapy was performed within 14 days before enrollment;

25. Have received anti-PD-1, anti-PD-L1, anti-PD-L2 or any other specific targeting T cell costimulation or checkpoint pathway antibodies or drug therapy;

26. Underwent major surgery within 28 days prior to enrollment, unless the surgery was minimally invasive (for example, central venous catheterization via peripheral venipuncture [PICC]);

27. For people with a history of uncontrolled epilepsy, central nervous system disease, or mental disorder, the investigator will determine whether the clinical severity hinders the signing of informed consent or affects the patient's compliance with oral medications;

28. There is a potential medical condition or alcohol/drug abuse or dependence that the investigator believes is not conducive to the administration of the study drug or that affects the interpretation of drug toxicity or adverse events.
