Camrelizumab Combined With FOLFOX Neoadjuvant Therapy for Resectable Gastric and Gastroesophageal Junctional Adenocarcinoma
Study Details
Study Description
Brief Summary
The aim of this study is to observe the efficacy, safety, postoperative pathological response rate and survival benefit of immume checkpoint inhibitor PD-1 SHR1210 combined with chemotherapy in neoadjuvant therapy of locally advanced resectable gastric and gastroesophageal junction adenocarcinoma. In addition ，the investigators will explore the relationship between the immunophenotype of gastric cancer and the efficacy and drug resistance of immunotherapy combined with chemotherapy, and screen out biomarkers that can predict the efficacy of immunotherapy.

Detailed Description
Neoadjuvant chemotherapy and neoadjuvant radiotherapy and chemotherapy can not only improve the surgical resection rate and postoperative pathological remission rate, but also prolong the postoperative recurrence-free survival and benefit patients.Recent studies have confirmed that immume point inhibitors PD-1 and CTLA-4 monoclonal antibody have a certain effect in advanced gastric and gastroesophageal junction adenocarcinoma which had experienced multi-line treatment. Furthermore，the FOLFOX protocol is recommended as a new adjuvant treatment for locally advanced gastric cancer.In order to further improve the surgical resection rate and survival rate by improving the efficacy of neoadjuvant therapy for locally advanced gastric and gastroesophageal junction adenocarcinoma, the investigators selected PD-1 monoclonal antibody combined with FOLFOX neoadjuvant therapy for locally advanced gastric and gastroesophageal junctions Adenocarcinoma.The aim of this study is to observe the efficacy, safety, postoperative pathological response rate and survival benefit of immume checkpoint inhibitor PD-1 SHR1210 combined with chemotherapy in neoadjuvant therapy of locally advanced resectable gastric and gastroesophageal junction adenocarcinoma. In addition ，the investigators will explore the relationship between the immunophenotype of gastric cancer and the efficacy and drug resistance of immunotherapy combined with chemotherapy, and screen out biomarkers that can predict the efficacy of immunotherapy.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: treatment group Neoadjuvant therapy:SHR1210 combined with FOLFOX repeat every 14 days for a total of 4 cycles. Adjuvant therapy:SHR1210 combined with chemotherapy (the specific regimen will be chosen at the discretion of the investigator), every 14 days for a total of 4 cycles. After that, the patients will receive camrelizumab monotherapy for up to 1 year (from the first SHR1210 treatment). |
Drug: SHR1210 combined with FOLFOX
SHR1210, iv, 200 mg d1, 30-minute intravenous infusion, repeated every 14 days.
FOLFOX: Oxaliplatin 85mg/m2 ivgtt 2h d1; 5-fluorouracil 400mg/m2 iv d1; leucovorin 400mg/m2 ivgtt 2h d1,5-fluorouracil 2400mg/m2 CIV 46h, repeated every 14 days Patients who have no disease progression and can tolerate surgery receive surgery. When the investigator believes that the patient is not suitable for continued medication or according to the RECIST 1.1 standard, the evaluation is PD and the medication is over. The PD-1 monoclonal antibody does not allow for reductions and can only delay or suspend medication.

Outcome Measures
Primary Outcome Measures
- R0 resection rate [Up to approximately 16 weeks]
The percentage of patients who have no residual cancer cells (gross or microscopically) at the resection margins.
- pathological complete response (pCR) rate [Up to approximately 16 weeks]
The percentage of patients with no residual cancer cells at the primary cancer site and N(-) per histological evaluation.
Secondary Outcome Measures
- Near pathological complete response (near-pCR) rate [Up to approximately 16 weeks]
Near-pCR rate is defined as the percentage of patients with grade 0-1 tumors per NCCN tumor regression grading (TRG).
- Overall survival(OS) [From randomization to the date of death (up to approximately 4 years)]
OS is defined as the time from the first dose to all-cause death.
- Progression-free survival(PFS) [up to 2 years]
PFS is defined as the time from the first dose to objective disease progression or death.
- Disease-free survival (DFS) [From randomization to the date of recurrence or death (up to approximately 4 years)]
DFS is defined as the time from the postoperative baseline imaging evaluation to disease recurrence or death in subjects who are disease-free after surgery.
- Percentage of Participants Who Experience One or More Adverse Events (AEs) [up to approximately 1 years]
The incidence and grade of adverse events (including serious adverse events and immune-related adverse events) will be determined per NCI-CTCAE 4.0.
