Brief summary: Enrolled patients with advanced solid tumors with neuroendocrine differentiation who had failed standard therapy (including those with initial advanced solid tumors with neuroendocrine differentiation and those with newly developed neuroendocrine differentiation after treatment failure) received the combination of serplulimab and surufatinib and continued to be administered until the patient developed disease progression or met other protocol criteria for discontinuation of study therapy. A total of 39 patients were enrolled.


Eligibility criteria: Inclusion Criteria:

-

1. Age ≥18 years old;

2. Histologically confirmed locally advanced late or metastatic unresectable solid tumors (lung cancer, gastric cancer, bowel cancer, etc.) with NED (neuroendocrinization, positive expression of at least one neuroendocrine marker CgA or Syn by immunohistochemistry), the initial standard treatment response is significantly lower than expected (tumor regression is not obvious, or PFS duration is short, as determined by the investigator);

1. Lung cancer: Locally advanced or metastatic (stage IIIB, IIIC, or IV) non-squamous non-small cell lung cancer (NSCLC) that is histologically or cytologically confirmed to be inoperable and not subject to radical concurrent radiotherapy and chemotherapy (according to the AJCC staging system Edition 8); Based on tissue examination, EGFR sensitive mutation, ALK, ROS1 gene fusion mutation was not detected driver gene negative;
2. Gastric cancer: histologically or pathologically confirmed advanced HER-2 negative gastric adenocarcinoma (including adenocarcinoma of the gastroesophageal junction);
3. Colorectal cancer: On the basis of adenocarcinoma diagnosis of colorectal cancer, morphologic neuroendocrine differentiation phenotype appears;
4. Breast cancer: histologically or pathologically confirmed advanced breast cancer, HER-2 negative;
5. Prostate cancer: advanced prostate cancer confirmed by histology or pathology, with positive staining of specific markers;

3.ECOG score: 0-1;

4. Patients with advanced solid tumors (lung cancer, stomach cancer, bowel cancer, etc.) with new neuroendocrine differentiation after previous standard treatment failure (or intolerance);

5. There is at least one CT measurable lesion according to RECIST 1.1 criteria;

6. Expect to survive for at least 3 months.

(7) Patients of reproductive age (including female and male patients' female companions) must use effective birth control measures;

8. Subjects voluntarily join the study and sign an informed consent form (ICF);

9. It is expected that the compliance is good, and the efficacy and adverse reactions can be followed up according to the protocol requirements.

Exclusion Criteria:

5. Patients with a definite tendency to gastrointestinal bleeding. Including the following conditions: ① there are locally active ulcer lesions, and stool occult blood 2+ or more; (Fecal occult blood 2+ was allowed to re-test fecal occult blood, and patients who were judged by the investigator to have clear benefits could be enrolled); ② Patients with history of black stool and hematemesis within 3 months;

1. Patients with unsatisfactory blood pressure control (systolic pressure ≥150 mmHg, diastolic pressure ≥100 mmHg);
2. have grade I or higher myocardial ischemia or myocardial infarction, arrhythmia (including QTc≥480ms), and ≥ grade 2 congestive heart failure (NYHA);
3. Active or uncontrolled severe infection (≥CTC AE grade 2 infection);
4. Cirrhosis, decompensated liver disease, active hepatitis or chronic hepatitis require antiviral therapy;
5. Renal failure requires hemodialysis or peritoneal dialysis;
6. Two consecutive urine routine indicated urine protein ≥++, and confirmed 24-hour urine protein quantity \> 1.0 g;
7. Suffering from mental illness, including epilepsy, dementia, severe depression, mania, etc.

9. Received major surgical treatment, open biopsy, or significant traumatic injury within 28 days prior to the grouping (specifically in conjunction with clinical evaluation);

10. With pleural effusion or ascites, causing respiratory syndrome (≥CTC AE grade 2 dyspnea);

11. Patients who had received chemotherapy, radiotherapy, or other experimental anti-cancer treatment (other than bisphosphonate) within 4 weeks prior to the first dosing of this study. Those who had previously received local radiotherapy were eligible if they met the following criteria: more than 4 weeks from the end of radiotherapy to the start of the study (more than 2 weeks for brain radiotherapy); In addition, the target lesions selected in this study were not in the radiotherapy area, or if the target lesions were in the radiotherapy area but had confirmed progression;
