Brief Summary

This is a prospective, exploratory clinical study. The primary endpoint of the study is to assess the pathological complete response (pCR) rate of tumors after neoadjuvant chemotherapy for rectal cancer using sintilimab combined with bevacizumab. The aim is to evaluate the efficacy and safety of sintilimab in combination with bevacizumab in the perioperative neoadjuvant chemotherapy for rectal cancer. The study includes two cohorts: Cohort A involves a retrospective collection of rectal cancer patients who previously received the XELOX regimen in the perioperative setting. Cohort B includes rectal cancer patients undergoing perioperative treatment with sintilimab and bevacizumab combined with XELOX as a neoadjuvant regimen. Each of the trial group and historical control group requires 59 cases. The administration method for the trial group (Cohort B) is as follows: Sintilimab: 200 mg, intravenous, Day 1, every 3 weeks. Bevacizumab: 7.5 mg/kg, intravenous, Day 1, every 3 weeks. Chemotherapy regimen: XELOX regimen.

• Total bilirubin ≤ 1.5 × upper limit of normal (ULN); if total bilirubin \> 1.5 × ULN but direct bilirubin ≤ ULN, enrollment is also allowed;

You may not qualify if:

• \- 1. Diagnosed with malignant diseases other than rectal cancer within 5 years prior to the first administration (excluding cured basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and/or completely excised in situ carcinoma); 2.Currently participating in an interventional clinical study treatment, or received other investigational drugs or used investigational devices within 4 weeks prior to the first administration; 3.Previously received the following therapies: anti-PD-1, anti-PD-L1, or anti-PD-L2 drugs, or drugs targeting another stimulus or co-inhibitory T cell receptors (including but not limited to CTLA-4, OX-40, CD137, etc.); 4.Received traditional Chinese medicine or immunomodulatory drugs with anti-tumor indications (including thymosin, interferon, interleukin, except for local use to control pleural effusion) within 2 weeks prior to the first administration.
• Experienced active autoimmune diseases requiring systemic treatment (e.g., use of disease-modifying drugs, glucocorticoids, or immunosuppressants) within 2 years prior to the first administration. Alternative therapies (e.g., thyroid hormone, insulin, or physiological glucocorticoids for adrenal or pituitary insufficiency) are not considered systemic treatment;
• Receiving systemic glucocorticoid treatment within 7 days prior to the first administration of the study (excluding nasal, inhaled, or other forms of local glucocorticoids) or any other form of immunosuppressive therapy;
• Note: Physiological doses of glucocorticoids (≤10 mg/day of prednisone or equivalent) are allowed;
• Presence of clinically uncontrollable abdominal effusion (patients who do not require drainage of effusion or who have not shown significant increase in effusion after stopping drainage for 3 days may be included);
• Known history of allogeneic organ transplantation (except for corneal transplantation) or allogeneic hematopoietic stem cell transplantation;
• Known allergy to the study drugs sintilimab, bevacizumab, or any active ingredients or excipients related to these investigational drugs;
• Presence of multiple factors affecting oral medication (e.g., inability to swallow, post-gastrointestinal resection, chronic diarrhea, and bowel obstruction);
• Not fully recovered from any toxicity and/or complications arising from any intervention prior to the start of treatment (i.e., ≤ grade 1 or return to baseline, excluding fatigue or hair loss);
• Known history of human immunodeficiency virus (HIV) infection (i.e., positive for HIV 1/2 antibodies);
• Untreated active hepatitis B (defined as HBsAg positive with HBV-DNA copies exceeding the upper limit of normal for the testing laboratory at the study site);
• Note: Hepatitis B subjects meeting the following criteria may also be included:
• HBV viral load \<1000 copies/ml (200 IU/ml) prior to the first administration; subjects should receive anti-HBV treatment throughout the study drug treatment period to prevent viral reactivation.
• Subjects with anti-HBc (+), HBsAg (-), anti-HBs (-), and HBV viral load (-) do not need to receive prophylactic anti-HBV treatment but require close monitoring for viral reactivation.
• Active HCV infection subjects (HCV antibody positive and HCV-RNA level above the lower limit of detection); 15.Received live vaccine within 30 days prior to the first administration (Cycle 1, Day 1); Note: Inactivated virus vaccine for seasonal influenza is allowed within 30 days prior to the first administration; however, intranasal live attenuated influenza vaccine is not permitted.
