Advanced Gastric Adenocarcinoma
Conditions
Brief summary
A Study of the Advanced Adenocarcinoma of Stomach and Gastroesophageal Junction With Camrelizumab+SOX Control Camrelizumab+SOX+ Trastuzumab
Detailed description
To observe the efficacy, safety, postoperative pathological remission rate and survival benefit of patients with HER-2 positive locally advanced adenocarcinoma of stomach and gastroesophageal junction treated with camrelizumab+SOX combined with trastuzumab or not.
Interventions
DRUGcamrelizumab
camrelizumab was administered intravenously at a fixed dose of 200 mg, on the first day, once every 3 weeks, with a cycle of 3 weeks. Infusion for 30 min each time (no less than 20 min and no more than 60min); SOX: Oxaliplatin: 130 mg/m2, administered intravenously, on the first day, once every three weeks, and every three weeks is a cycle; S-1: according to BSA (\< \<1.25 40 mg；; 1.25-1.5 50 mg； \> \>1.5 60 mg), oral administration, d1-d14 twice a day, 3 weeks as a cycle; Trastuzumab was administered intravenously, with an initial loading dose of 8 mg/kg and a subsequent dose of 6 mg/kg, with a cycle of 3 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pathological complete response rate(pCR） | up to 2 years | Refers to the absence of tumor cell residue in the primary tumor. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease-free survival | up to 2 years | Defined as postoperative disease-free subjects, starting from the time of postoperative baseline imaging evaluation to the time of disease recurrence or death. |
| Overall survival | up to 2 years | defined as the time from the first medication to the death of a subject from any cause after enrollment. For the subjects who survived at the last contact, their total survival will be deleted on the last contact day. |
| Major pathological response rate | up to 2 years | The survival tumor cells in the resected specimen were ≤10%. |
| R0 resection rate | up to 2 years | There was no macroscopic tumor at the surgical margin, and the tumor cells at the surgical margin were negative within 1mm under microscope. |
