Stomach Neoplasms Clinical Trial
— NeoRacingOfficial title:
A Randomized Phase II Trial of Perioperative Chemoimmunotherapy Verses Perioperative Chemoimmunotherapy Plus Preoperative Chemoradiation for Locally Advanced Gastric (G) or Gastroesophageal Junction (GEJ) Adenocarcinoma
NeoRacing is a randomized phase II trial carried out at Fudan University Shanghai Cancer Center (FUSCC) in China. The study can be divided into the screening stage, treatment stage and follow-up stage. The enrolled patients will receive perioperative SOX chemotherapy, PD-1 antibody (sintilimab) and radical surgery, with or without preoperative CRT. The patients were randomized by stratified permutated block randomization on a web-based system . The status of peritoneal cytological examination (CY0 vs. CY1) was the stratification factor. The study protocol was approved by the Ethics Committee of FUSCC. All patients provided written informed consent before recruitment. Monitoring will be carried out in this tri

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | To study the association of baseline PD-L1 CPS, TMB, MSI/MMR status, and EBER status on the efficacy of immunotherapy. | 36 months after the recruitment of the last subject. | ||
Other | To study the association between gut microbiota and the efficacy of immunotherapy. | 36 months after the recruitment of the last subject. | ||
Other | To study the association between the Helicobacter pylori infection status and the efficacy of immunotherapy. | 36 months after the recruitment of the last subject. | ||
Other | To study the influence of preoperative therapy on the tumor immune microenvironment (TIME) and systemic immune status. | 36 months after the recruitment of the last subject. | ||
Primary | Pathological complete regression (pCR) rate | The primary endpoint is the pathological complete regression (pCR) rate: the proportion of patients who achieve pCR after preoperative therapy. Patients with a CY0 status at the time of enrollment should have no residual tumor cells in the primary lesion and in the dissected lymph nodes in the surgical specimens (ypT0N0M0). Patients with a CY1 status at the time of enrollment should reach both ypT0N0M0 and a CY0 status. | 6 months after the enrollment of the last subject | |
Secondary | Pathological response rate (pRR) | 1) The pathological response rate (pRR) is defined as the proportion of patients with a pathological response. The tumor regression will be evaluated according to Ryan's tumor regression grading (TRG). The pathological response is defined as TRG0 and TRG1 of the primary lesion after preoperative therapy. | 6 months after the enrollment of the last subject | |
Secondary | R0 resection rate | The R0 resection rate is defined as the proportion of patients who achieve R0 resection. For patients with a CY0 status at the time of recruitment, the tumor should be completely removed, and no residual tumor cells within 1 mm of the resection margin should be confirmed by postoperative pathology. For patients with a CY1 status at the time of recruitment, an extra requirement is that CY0 should be confirmed by an peritoneal cytological examination. | 6 months after the enrollment of the last subject | |
Secondary | Objective response rate (ORR) | The Objective response rate (ORR) is defined as the proportion of patients with a complete response (CR) or a partial response (PR) to preoperative therapy. The ORR will be evaluated using the RESIST1.1 protocol. | 6 months after the recruitment of the last subject. | |
Secondary | Event-free survival (EFS) | The EFS will be calculated from the date of randomization to the date of any event or censoring. The event is defined as below: (1) locoregional recurrence; (2) peritoneal seeding; (3) distant metastasis; (4) death of any reason; (5) tumor progression according to RESIST 1.1. | 36 months after the recruitment of the last subject. | |
Secondary | Overall survival (OS) | The OS will be calculated from the date of randomization to the date of death or date of the last follow-up. | 36 months after the recruitment of the last subject. | |
Secondary | Safety of perioperative therapy include chemo(radio)therapy and PD-1 antibody. | Treatment related adverse events (TRAEs) of perioperative therapy will be graded and documented according to NCI-CTC AE v5.0 from the beginning of treatment to 28 days after the last date of treatment. Documentary will include the occurrence time, severity and time of duration. Common TRAEs include leukopenia, thrombocytopenia, anemia, ALT/AST increase, BUN/Scr increase, nausea, vomiting, diarrhea, appetite decrease, pruritus, rash, fatigue, malaise and pyrexia. Additional TRAEs of special interest include pneumonitis, interstitial lung disease, acute hepatitis, hyperthyroidism, autoimmune thyroiditis, thyroid disorder, hypopituitarism, colitis, maculopapular rash and epidermal capillary hyperplasia. | One month after the last date of treatment | |
Secondary | Safety of surgery after preoperative therapy include chemo(radio)therapy and PD-1 antibody. | Surgery related adverse events (SRAEs) refer to complications which happen during or one month after surgery. Severe complications after surgery will be documented and classified by Clavien-Dindo grading, such as abdominal or GI tract bleeding, anastomotic fistula, pancreatic fistula of grade B or above, and incision complications (infection, bleeding, rupture). | During or one month after surgery |
