    During the study

Study Arms (2)

Late standard first-line treatment regimen group

OTHER

Fluorouracil and platinum were used as the basic chemotherapy regimens, with or without targeted therapy, and no additional injection of PCSK9 inhibitors

Drug: standard advanced first-line regimen group

PCSK9 inhibitor in combination with standard advanced first-line regimen group

EXPERIMENTAL

Fluorouracil and platinum as the base chemotherapy regimen, with or without targeted therapy, was administered subcutaneously at a fixed dose of 150 mg of PCSK9 inhibitor every two weeks starting on day 1 of patient enrollment

Drug: PCSK9 inhibitor in combination with standard advanced first-line regimen group

  • preoperative pathological diagnosis of advanced colorectal adenocarcinoma without pMMR/MSS, with the chance of radical surgical treatment;
  • Hypolipidemia caused by combination with other long-term lipid-lowering drugs;
  • malignancies other than colorectal cancer with negligible risk of metastasis or death (e.g., expected 5-year OS \>90%) within 5 years prior to enrollment and for which a radical outcome is expected after treatment (e.g., adequately treated carcinoma in situ of the uterine cervix, basal or squamous cell skin cancers, limited prostate cancers treated for radical purposes, ductal carcinomas in situ treated for radical purposes surgically), with the exception of (b) the following;
  • history of autoimmune diseases, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis;
  • major surgery within 4 weeks prior to enrollment or incomplete recovery from previous surgery;
  • systemic immunostimulatory drug therapy (including but not limited to interferon or IL-2) within 4 weeks or 5 half-lives of the drug, whichever is shorter, prior to enrollment;
  • pre-existing or clinically significant CNS disease at screening, such as epilepsy, seizures, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, organic brain syndromes, or psychiatric disorders;
  • receipt of systemic corticosteroids (\>10 mg/d prednisone equivalent) or other systemic immunosuppressants, etc. within 2 weeks prior to randomization;
  • previous allogeneic bone marrow transplantation or previous solid organ transplantation;
  • subjects who, in the judgment of the Investigator, have any factors affecting compliance with the protocol, including uncontrollable medical, psychological, familial, sociological, or geographic conditions; or who are unwilling or unable to comply with the procedures required in the study protocol;
  • history of idiopathic pulmonary fibrosis, drug-induced pneumonia, organic pneumonia (i.e., occlusive bronchiolitis), idiopathic pneumonia, or evidence of active pneumonia on CT scan of the chest at the time of screening; 13. receipt of any live vaccine (e.g., vaccines against infectious diseases such as influenza vaccine, varicella vaccine, etc.) within 4 weeks (28 days) prior to randomization
  • \. Pregnant or lactating female patients;
  • \. Hypersensitivity to fluorouracil-based or platinum-based agents or their excipients.
