Brief Summary

This study aims to explore whether the combination of surufatinib (anti-angiogenic therapy) and sintilimab (PD-1 inhibitor) on the basis of EP regimen can further improve the effective rate and survival time of first-line treatment for patients with advanced gastric neuroendocrine carcinoma, and explore the safety and tolerability of this regimen.

Conditions

Gastric Neuroendocrine Carcinoma

Keywords

gastric neuroendocrine carcinoma; Sintilimab; Surufatinib

Outcome Measures

Primary Outcomes (1)

• ORR

  It refers to the proportion of patients whose tumors have shrunk to a certain amount and maintained for a certain period of time, including CR and PR cases. Solid tumor response assessment criteria (RECIST 1.1 criteria) were used to evaluate objective tumor response. Participants had to have a measurable tumor lesion at baseline, and response criteria were classified as complete response (CR), partial response (PR), stable disease (SD), and disease progression (PD) according to RECIST 1.1 criteria.

  3 years

Secondary Outcomes (1)

• PFS

  3 years

Study Arms (1)

Sintilimab + Surufatinib + EP

Sintilimab: 200mg intravenously administered on day 1; Surufatinib: 200mg/ day orally, taken continuously; Etoposide: 1, 2, 3 days of continuous administration, 100mg/m2, intravenous infusion; Cisplatin: 75mg/m2 on day 1, or 25mg/m2 on day 1, 2, and 3, intravenous infusion;

Drug: Sintilimab，Surufatinib

Interventions

Sintilimab，Surufatinib DRUG

Based on the standard EP regimen, the combination of surufatinib (anti-angiogenic therapy) and sintilimab (PD-1 inhibitor) were used among patients with advanced gastric neuroendocrine carcinoma.

Sintilimab + Surufatinib + EP

Study Population

First-line treatment for advanced gastric neuroendocrine carcinoma

You may qualify if:

• Locally advanced or metastatic gastric neuroendocrine carcinoma (NEC), hyperproliferative neuroendocrine tumor (NET G3) or mixed neuroendocrino-non-neuroendocrine tumor (MiNEN), as demonstrated by pathology (WHO classification criteria 2019), may also be included;
• Have not received systematic anti-tumor therapy before;
• Have received radical treatment in the past and have no treatment interval from the end of chemotherapy, radiotherapy, or chemoradiotherapy to relapse for at least 6 months (the end time of the last chemotherapy cycle/the end time of the last radiotherapy);
• There are measurable lesions defined by the RECIST 1.1 standard;
• At least 18 years old;
• ECOG physical condition: 0-1 score;
• Expected survival of more than 3 months;
• If the major organs function normally, the following criteria are met:
• Blood routine examination: hemoglobin (Hb) ≥90g/L; Absolute neutrophil count (ANC) ≥1.5×10\^9/L; Platelet (PLT) ≥100×10\^9/L; White blood cell count (WBC) ≥3.0×10\^9/L;
• Biochemical examination: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5×ULN (tumor liver metastasis, ≤5×ULN); Serum total bilirubin (TBIL) ≤1.5×ULN (Gilbert syndrome subjects, ≤3×ULN); Serum creatinine (Cr) ≤1.5×ULN or creatinine clearance ≥50ml/min;
• Coagulation function: activated partial thromboplastin time (APTT), International Standardized ratio (INR), prothrombin time (PT) ≤1.5×ULN;
• The subjects voluntarily joined the study, signed the informed consent, and the compliance was good.

You may not qualify if:

• Patients with any of the following conditions were excluded from the study:
• The presence of a serious illness or medical condition, including but not limited to the following:
• Known recurrence in situ or metastasis at any other site;
• systemic active infection (i.e. infection resulting in body temperature ≥38 ° C);
• Clinically significant intestinal obstruction, pulmonary fibrosis, renal failure, liver failure, or symptomatic cerebrovascular disease;
• Severe/unstable angina, New York Heart Association (NYHA) Class III or IV symptomatic congestive heart failure;
• Clinically significant gastrointestinal bleeding;
• Known presence of human immunodeficiency virus (HIV) or acquired conventional immunodeficiency syndrome (AIDS) - associated disease, or active hepatitis B or C;
• Pregnant or lactating women;
• The researcher considers it inappropriate to enter this study.
