    Abstract: Oxaliplatin plus S-1 (SOX) was a first-line regimen for advanced gastric cancer. The continuous administration of S-1 for 3 weeks can result in unacceptable gastrointestinal and hematological toxicities. Therefore, an alternative regimen (administration of S-1 for 1-week followed by 1-week rest) is warrant for improved tolerability and noninferiority efficacy. We conducted a study to evaluate the efficacy and safety of biweekly SOX as the first-line chemotherapy in patients with metastatic or advanced gastric cancer in China. Patients with metastatic or previously untreated advanced gastric cancer were enrolled. Oxaliplatin was administered intravenously at a dose of 85 mg/m 2 on day 1, while S-1 was administered orally in doses of 80, 100, or 120 mg/day depending on different body surface areas of 〈 1.25 m 2 , 1.25–1.5 m 2 , or 〉 1.5 m 2 respectively; the total dose of S-1 was administered twice daily on days 1–7 followed by a 7-day rest. This schedule was repeated every 2 weeks until disease progressed or intolerable toxicity occurred. Forty-six patients (M/F = 33/13) received biweekly oxaliplatin and S-1 as first-line chemotherapy. A total of 257 treatment cycles were administered and the median number of cycles administered was 6. Thirty-six patients (78.3%) received second-line chemotherapy. The median progression free survival and median overall survival was 4.4 months (95% CI, 3.37–5.36 months) and 10.3 months (95% CI, 8.88–11.3 months), respectively. The 1-year and 2-year survival rate was 41% and 13%. The objective response rate was 30.43%, and the disease control rate was 76.08%. The observed adverse events of Grade 3/4 included were leukocytopenia (13.04%); anemia (13.04%); neutropenia (15.22%); neurological toxicity (2.17%); diarrhea (2.17%). The biweekly SOX regimen as first-line treatment was active and well tolerated in Chinese patients with metastatic or advanced gastric cancer.

    Abstract: Background. Chemoimmunotherapy has become the first-line treatment for unresectable esophageal squamous cell carcinoma (ESCC). Still, reliable biomarkers to identify patients who could benefit from this combined therapy remain uncertain. This study focused on elucidating the predictive significance of the monocyte-to-lymphocyte ratio (MLR) and establishing the prognostic nomogram for unresectable ESCC treated with chemoimmunotherapy. Methods. Data of clinical features, peripheral blood parameters, and treatment records were collected in unresectable ESCC patients who received PD-1/PD-L1 inhibitors plus chemotherapy as the first-line treatment from September 2017 to August 2021. The nomogram based on MLR and clinical parameters for predicting the overall survival (OS) was developed and validated. Results. Out of 81 patients enrolled, patients with a lower MLR had significantly longer progression-free survival (PFS) and OS than patients with a higher pretreatment MLR (p = 0.0067; p = 0.00069). The OS nomogram integrating MLR, performance status (PS) score, and body mass index (BMI) achieved a C-index of 0.770 (95%CI 0.645–0.896). The area under the ROC curve (AUC) value of the nomogram predicting 12-, 18-, and 24-month OS rates were 0.855, 0.792, and 0.744, respectively, which were higher than the clinical TNM staging system or the MLR. Stratified by the nomogram-generated scores, three risk groups (low, moderate, and high) in survival curves manifested a distinct difference (p 〈 0.0001). Conclusion. MLR emerged as an independent predictive factor for PFS and OS in treatment-naive unresectable ESCC patients treated with chemoimmunotherapy. The constructed nomogram of MLR and clinical parameters was a reliable model for prognostic estimation.

    Abstract: 3021 Background: AK109 is a fully-human monoclonal antibody that specifically binds to vascular endothelial growth factor receptor 2 (VEGFR2), thereby block vascular endothelial growth factor (VEGF)/VEGFR2 signaling pathway to inhibit angiogenesis, endothelial cell migration and proliferation of tumor cells. This phase I study is the first-in-human trial of AK109, which was designed to evaluate safety, tolerability of AK109, to determine the maximum tolerated dose (MTD), recommend phase II dose (RP2D) and to gain preliminary data on pharmacokinetics (PK), pharmacodynamics, immunogenicity and clinical activity for AK109 in pts with advanced or metastatic solid tumors resistant to standard therapies (NCT04547205). Methods: This open-label, multi-center, phase I study included a dose escalation phase (part 1) using a 3+3 design to determine MTD and potential RP2D (n = 36 max), with planned dosing of 2, 4, 8, 12 and 18 mg/kg q2w and 15mg q3w, followed by a dose expansion phase (part 2), at 2 potential RP2Ds in q2w or q3w respectively (n = 24-30). The PK characteristics, dose limiting toxicity (DLT), adverse events per CTCAE 5.0 and efficacy (ORR, DCR, DoR, PFS per RECIST v1.1, OS, etc.) of AK109 were evaluated. Results: As of December 30 th , 2021 (median follow-up: 6.0 months), 40 pts (median age: 59.5 years) were enrolled, 16 pts in part 1 and 24 pts in part 2. No DLT was observed AK109 in part 1. Tumor types included gastric cancer (n = 9), non-small cell lung cancer (n = 8), hepatocellular carcinoma (n = 8), colorectal cancer (n = 5), pancreatic carcinoma (n = 2) and oesophagus cancer (n = 2), etc. Preliminary PK analyses showed systemic exposure in C max and AUC last increased dose proportionally at doses of 8 mg/kg and above, with a mean half-life of 8.5 to 10 days. 12mg/kg q2w and 15mg/kg q3w were selected as RP2Ds. Average exposure of AK109 was 6.9 cycles. Eight pts received over 10 cycles of AK109. Treatment related adverse events(TRAE) occurred in 38 (95%) of all pts. Grade 3 and 4 TRAE occurred in 16 (40%) of all pts. The most common TRAEs were proteinuria (22/40, 55%), hypertension (13/40, 32.5%) and AST increased (11/40, 27.5%). Serious adverse event (SAE) occurred in 11 (27.5%) pts, 2 (5%) of which were AK109 related. ORR and DCR were 10.0% and 62.5%, respectively. The median PFS of non-small cell lung cancer (n = 8) and gastric cancer (n = 9) were 5.6 months (95% CI, 1.3, NE) and 5.5 months (95% CI, 1.4, NE), respectively. Conclusions: AK109 showed manageable safety and promising anti-tumor activity. Two phase II studies of AK109 combined with AK104 (anti PD-1/CTLA-4 bi-specific antibody) are ongoing to evaluate the efficacy of AK109 combined with AK104 in patients with multiple solid tumors (NCT05142423, NCT04982276). Clinical trial information: NCT04547205.

    Abstract: 4042 Background: Immune checkpoint inhibitors have shown clinical benefit in advanced GC/GEJC. This phase 1b study evaluates the efficacy and safety of sintilimab, an anti-programmed cell death-1 antibody (PD-1 Ab) in combination with XELOX for GC/GEJC in first-line setting. Methods: This phase 1b study enrolled treatment-naïve unresectable locally advanced or metastatic GC/GEJC patients without HER2 amplification in cohort F. Patients received sintilimab 200mg IV q3w until disease progression, unacceptable toxicity or death, in combination with XELOX regimen (oxaliplatin 130mg/m 2 IV D1 and capecitabine 1000mg/m 2 PO BID D1-14) for up to 6 cycles. The primary objective was to evaluate the efficacy of the combination per RECIST v1.1 and safety and tolerability. Results: Totally 20 patients were enrolled in cohort F. As data cutoff (15 Jan 2019), median follow up was 5.8 months (range, 2.4 to 12.5). The median dose of sintilimab was 6.5 (range, 4 to 12). The objective response rate (ORR) was 85.0% (95%CI, 62.1 to 96.8) and disease control rate (DCR) was 100.0% (95%CI, 83.2 to 100.0). Among 17 patient with BOR of PR, two patients achieved a complete response (CR) of the target lesion. The median duration of response (DOR) and median progression free survival (PFS) had not been met. Three patients underwent resection of primary tumor after achieving a BOR of partial response (N=2) and stable disease (N=1). The incidence of treatment emergent adverse events (TEAEs) was 85.0%. Treatment-related AEs (TRAEs) occurred in 14 (70.0%) patients. The incidence of TRAE ≥ Grade 3 was 15%. AEs of immune-related etiology, occurred in 6 patients (30.0%). There were no AEs that resulted in death. As data cutoff, 12 patients were still in treatment and 8 had discontinued treatment and were under survival follow up. The biomarker analysis including PD-L1 expression in tumor specimen was ongoing. Conclusions: Sintilimab in combination with XELOX in first-line GC/GEJC shows promising anti-tumor efficacy and a tolerable safety profile. The further randomized, phase 3 study of Sintilimab in combination with XELOX in this setting is ongoing (NCT03745170). Clinical trial information: NCT02937116.

    Abstract: Sintilimab blocks the interaction between programmed death-1 (PD-1) and its ligands. The safety and efficacy of sintilimab combined with oxaliplatin/capecitabine (CapeOx) as first-line treatment were evaluated in patients with gastric (G)/gastroesophageal junction (GEJ) adenocarcinoma in a phase Ib clinical trial. Methods Patients with locally advanced or metastatic G/GEJ adenocarcinoma without previous systemic treatment were enrolled as one cohort of a multi-cohort study. Sintilimab was administered at a dose of 200 mg intravenously (IV) in combination with CapeOx (1000 mg/m 2 capecitabine orally, bid, D1–14 and 130 mg/m 2 oxaliplatin IV, D1) every 21 days for up to 6 cycles. After combination treatment, patients continued to receive sintilimab (200 mg) at 3 weekly intervals as maintenance therapy until progressive disease (PD), unacceptable toxicity, withdrawal of informed consent, or for up to 24 months. Adverse events (AEs) were monitored to assess safety in terms of their frequency, intensity and causality. The efficacy endpoints included the objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). Tumor mutation burden (TMB) was evaluated for its association with clinical response. Results A total of 20 patients were enrolled and received sintilimab plus CapeOx. All patients reported treatment-related AEs (TRAEs). Grade 3–4 TRAEs were found in 11 (55.0%) patients. Seventeen patients obtained partial response and the ORR was 85.0% (95% CI: 62.1–96.8%). Three (15.0%) had stable disease and DCR was 100.0% (95% CI: 83.2–100.0%). As data cutoff of May 1, 2019, the median follow-up was 7.8 months. The median PFS was 7.5 months (95% CI: 6.2–9.4) and median OS had not been reached. The OS rates at 6 months and 12 months were 100.0 and 68.0%. No association was observed between TMB and efficacy. Conclusions Sintilimab combined with CapeOx as first-line treatment demonstrated acceptable safety and promising efficacy. Trial registration ClinicalTrials.gov, NCT02937116 . Registered 8 October 2016.

    Abstract: e16097 Background: Sintilimab plus XELOX has been proven to be efficacious in the first line treatment of gastric cancer. Dual inhibition of PD-1 and lymphocyte-activation gene 3 (LAG-3) may improve anti-tumor effect synergistically. IBI110 (anti-LAG-3 mAb) plus sintilimab (anti-PD-1 mAb) has shown preliminary antitumor activity in advance solid tumors. This phase Ib cohort study evaluated the safety and efficacy of IBI110 in combination with sintilimab and XELOX regimen for advanced HER2-negative gastric or gastroesophageal junction adenocarcinoma (G/GEJ AC) in first-line setting. Methods: This phase Ib study enrolled patients with previously untreated, unresectable, locally advanced or recurrent/metastatic HER2-negative GC/GEJAC. Patients received IBI110 200mg IV Q3W and sintilimab 200mg IV Q3W plus oxaliplatin and capecitabine (XELOX) until disease progression, unacceptable toxicity or death. The primary objective was to evaluate the safety and tolerability, and efficacy of the combination therapy. Results: As data cutoff January 20 th 2022, 18 patients were enrolled, 6 patients had locally advanced/recurrent tumors, and 12 had metastatic tumors. The median follow up time was 4 weeks (range, 0-20). The median exposure of combination therapy was 9.4 weeks (range, 3-24). Any grade TRAEs occurred in 16 pts (88.9%); most commonly white bloo4d cell count decreased (n = 6; 33.3%), neutrophil count decreased (n = 6; 33.3%), and aspartate aminotransferase increased (n = 6; 33.3%). Grade ≥ 3 TRAEs occurred in 5 pts (27.8%), including neutrophil count decreased (n = 2; 11.1%), platelet count decreased (n = 2; 11.1%) and hepatic function abnormal (n = 2; 11.1%), platelet count decreased (n = 2; 11.1%) and hepatic function abnormal (n = 2; 11.1%). Immune-mediated AEs occurred in 7 pts (38.9%); most commonly amylase increased (n = 2; 11.1%). One patient discontinued treatment because of the coronary artery disease. There were no treatment-related death. For 15 evaluable patients, the ORR and DCR were 60% (9 PR) and 100% (9 PR,6 SD), respectively. The median duration of response (DOR) and median progression free survival (PFS) were not reached. As data cutoff, 17 patients were still in treatment. Conclusions: In this phase Ib study, IBI110 in combination with sintilimab and chemotherapy was well tolerated in the first line treatment of G/GEJ AC and the clinical benefit need more follow up time to be elucidated. Clinical trial information: NCT04085185.

    Abstract: The emergence of immune checkpoint inhibitors has changed the landscape of first-line treatment of patients with advanced gastric cancer. Currently, the prognostic significance of inflammatory markers in first-line immunotherapy combined with chemotherapy for gastric cancer is currently unclear. This study aimed to identify inflammatory markers with potential to predict treatment outcome in advanced gastric cancer patients receiving immunotherapy combined with chemotherapy. Methods This retrospective study enrolled untreated advanced or metastatic gastric or gastro-esophageal junction cancer patients from 5 clinical trials (the clinical trial cohort) and the real world (the real-word cohort). Inflammatory markers included in the analysis included neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation index (SII), and derived neutrophil-to-lymphocyte ratio (dNLR). Receiver operating characteristic (ROC) curves were constructed to identify optimal cut-off values. The prognostic potential of the markers was determined using Kaplan–Meier analysis, univariate and multivariate Cox-regression analyses in the clinical trial cohort and the findings were validated in the real-world cohort. Results In the clinical trial cohort (n=45), MLR, PLR and SII were associated with PFS but not OS (All P & lt;0.05), while dNLR was not correlated with PFS or OS. Only NLR was associated with PFS and OS and identified as an independent prognostic predictor in the univariate and multivariate analyses. The prognostic value of NLR was validated in the real-world cohort (n=55). Conclusions NLR was a strong predictor of PFS and OS in patients with advanced gastric cancer receiving immune checkpoint inhibitors combined with chemotherapy. Further prospective studies are required to validate our results.

    Abstract: Notwithstanding that the past decade has witnessed unprecedented medical progress, gastric cancer (GC) remains a leading cause of cancer death, highlighting the need for effective prognostic markers. The Memorial Sloan Kettering Prognostic Score (MPS) has been validated as a valuable prognostic tool for patients with metastatic pancreatic adenocarcinoma (mPDAC). This study aimed to assess the prognostic value of the MPS in advanced GC. Methods Data from 367 patients were analyzed in the present study. The MPS for each patient was calculated based on the sum of scores based on the neutrophil‐to‐lymphocyte ratio and serum albumin levels. Multivariate analyses were performed to identify the independent clinicopathological parameters associated with overall survival (OS). Further subgroup analyses based on clinicopathological features were conducted. Results Patients with MPS 0 ( n  = 161), MPS 1 ( n  = 158), and MPS 2 ( n  = 48) exhibited significantly different OS, with a median survival duration of 20.7 (95%CI: 12.2–29.2), 14.9 (95%CI: 12.5–17.3), and 12.7 (95%CI: 9.3–16.0) months, respectively ( p   〈  0.001). Significant differences in survival were observed among different groups of patients receiving chemotherapy (18.5 months vs. 14.7 months vs. 11.0 months, p  = 0.03) or the subgroup receiving chemotherapy plus immunotherapy as first‐line treatment (32.6 months vs. 17.7 months vs. 12.7 months, p  = 0.02). The MPS was identified as an independent prognostic factor in multivariate analysis. During subgroup analyses, MPS‐low (MPS 0) was consistently associated with a better prognosis than MPS‐high (MPS 1 or 2). Conclusions MPS is a practical, simple, and useful prognostic tool for patients with advanced GC. Further studies are warranted to validate its prognostic value in advanced GC.
