NCT06647680 | NOT YET RECRUITING | Rectal Cancer Patients

Neoadjuvant Chemotherapy and PD-1 Inhibitor for Locally Advanced Rectal Cancer
Sponsor:

The Affiliated Hospital of Qingdao University

Brief Summary:

To evaluate the safety and preliminary efficacy of preoperative chemotherapy and PD-1 inhibitor Tislelizumab for Rectal Cancer patients.Go through laboratory and medical tests to verify eligibility to enter the study, receive the experimental combination of drugs CAPOX (Oxaliplatin and Capecitabine) for 3 cycles prior to surgery and undergo laboratory tests and study procedures on specified days during the study period, complete end of study evaluations and tests, and participate in post-study follow up every three months for three years.

Condition or disease

Rectal Cancer Patients

Intervention/treatment

Receive the experimental combination of drugs (chemoradiation (Oxaliplatin and Capecitabine) + PD-1 inhibitor (Tislelizumab) for 3 cycles

Phase

PHASE2

Detailed Description:

Treatment will continue until participants experiences disease progression, unacceptable toxicity or withdraws consent and will include chemotherapy and PD-1 inhibitor (Tislelizumab) x 3 cycles (9 weeks). For participants experiencing unacceptable CAPOX or Tislelizumab related toxicity, yet obtaining therapeutic benefit, participants will be allowed to continue treatment, if well tolerated at the discretion of the investigator.After the completion of 3 cycles of treatment, the patients will rest for 2 weeks and then undergo surgery, and adjuvant therapy will be decided according to the postoperative pathology. Upon discontinuation of study treatment, participants will receive safety follow-up assessments approximately 30 and 90 days later. Once the 90-day safety follow-up is complete, participants will enter the survival follow-up period where they will continue to be followed approximately every three months until death, withdrawal of consent, or overall study completion. Patients will be followed for survival for 36 months from enrollment.
