RecruitingDrug trialNeoadjuvant Serplulimab & Bevacizumab With FOLFOX vs. FOLFOX Alone in RAS/BRAF WT, pMMR/MSS CRC PatientsThe primary objective of this study is to assess whether the addition of Serplulimab (a PD-1 inhibitor) and Bevacizumab (an anti-angiogenesis agent) to the standard FOLFOX chemotherapy can enhance the immune microenvironment in the liver, increase T lymphocyte infiltration, and consequently improve the postoperative prognosis for patients with surgically resectable colorectal cancer liver metastases (RAS/BRAF wild-type, pMMR/MSS) compared to FOLFOX alone.
