Clinical Trial Summary

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


Description:

Perioperative chemotherapy (ChT) and preoperative chemoradiation (CRT) are both the standard treatments for locally advanced gastric cancer (LAGC). CRT can achieve a higher pathological complete regression (pCR) rate, but whether this higher pCR rate can be transformed into a long-term survival benefit remains inconclusive. Therefore, relevant studies are in progress. On the other hand, immunotherapy has been established for the first-line treatment of advanced gastric cancer (AGC) and has been widely explored in the perioperative setting. The combination of chemotherapy/radiotherapy and immunotherapy may have a synergistic effect, which will lead to a better antitumor effect. The preliminary reports of ongoing studies show promising results, including a further improved pCR rate. However, the preferred treatment combination for LAGC is still not established. To solve this problem, we are carrying out this randomized phase II trial, which aims to evaluate the efficacy and safety of perioperative chemotherapy plus the use of PD-1 antibodies with or without preoperative chemoradiation for LAGC.

The results of the NeoRacing study will provide important information concerning the application of PD-1 antibodies in LAGC patients during the preoperative setting. Meanwhile, the two treatment protocols will be compared in terms of efficacy and safety.

Intervention

Drug:
Oxaliplatin
The SOX regimen consists of S-1 and oxaliplatin and is repeated every three weeks. Oxaliplatin will be administered intravenously at 130 mg/m2 on day 1.
Tegafur-Gimeracil-Oteracil
The SOX regimen consists of S-1 and oxaliplatin and is repeated every three weeks. S-1 is administered orally at 40-60 mg twice a day for 14 consecutive days. Then, the patients will have a one-week rest period. The dose of S-1 is according to the body-surface area (BSA): patients with a BSA of less than 1.25 m2 receive 80 mg daily; those with a BSA of 1.25 m2 or more but less than 1.5 m2 receive 100 mg daily; and those with a BSA of 1.5 m2 or more receive 120 mg daily.
Sintilimab
The immunotherapy includes perioperative treatment and postoperative maintenance treatment. The PD-1 mAb used will be sintilimab, and the dose is 200 mg intravenously every three weeks. Regardless of which arm, the courses of immunotherapy that will be received by the enrolled patients are the same: 3 times preoperatively, 3 times postoperatively, and then maintained until one year after surgery.
Radiation:
Concurrent chemoradiation
The radiotherapy (RT) consists of 45 Gy delivered in 25 fractions every five days per week for five weeks. The dose of concurrent ChT is 60 mg/m2 S-1 orally, oral tablets twice daily, days 1-5 of each week.
Procedure:
D2/R0 gastrectomy
Gastrectomy with standard D2 lymphadenectomy is recommended. The type of gastrectomy performed depends on the location and extent of the primary lesion. For GEJ or upper third tumors, a 3 cm esophageal margin is recommended, and a total gastrectomy or esophagogastrectomy is performed. For middle third tumors, the gastric margin is recommended to be more than 5 cm, and a total gastrectomy is performed. For lower third tumors, a 2 cm duodenal margin is recommended, and a subtotal or total gastrectomy is performed. Billroth I or Roux-en-Y gastrojejunostomy is performed for distal gastrectomy patients. Roux-en-Y esophagojejunostomy is performed for patients receiving total gastrectomy.

Outcome

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
