Study Details

Study Description

Brief Summary

This study is a single-arm, open-label, multicenter clinical study to evaluate the efficacy and safety of preoperative short-course radiotherapy combined with AK104 and chemotherapy + TME surgery in patients with advanced rectal cancer.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

Studies included a screening period (no more than 28 days after participants signed informed consent form to 28 days before first dose), treatment (receiving appropriate treatment until disease progression, intolerable toxicity, withdrawal of informed consent, death or study end, whichever occurs first), and follow-up (including safety follow-up and survival follow-up).

Eligible subjects will receive short-course radiotherapy (SCRT), IMRT/VMAT, pelvic 25Gy/5f/1 week. Two weeks after the end of treatment, subjects continued to receive neoadjuvant chemotherapy combined with immunotherapy regimen for 4 cycles: AK104 10 mg/kg, intravenous infusion every 3 weeks (Q3W), plus CAPOX (capecitabine: 1000mg/m2, bid, po, d1-14, oxaliplatin: 130mg/m2, ivgtt, d1), Q3W. Neoadjuvant therapy was assessed 2 weeks after the end of neoadjuvant therapy, and TME surgery was performed 4 weeks after the end of neoadjuvant therapy (R0 surgery was performed). Patients are not recommended to enter the organ preservation observation; If the efficacy after preoperative chemoradiotherapy is evaluated as clinical complete remission (cCR) and the patient strongly refuses surgery, the patient should be informed of the risk of recurrence and ask the patient to sign a rejection of surgery. Medication safety is assessed and, depending on the severity of adverse events (AEs) and drug relevance, investigators will take steps to ensure subject safety. After surgery (or patients who strongly refuse surgery) there is a 30- and 90-day safety follow-up, and survival assessments are performed every 3 months to obtain survival information and collect new tumor treatment information until the death of the participant, withdrawal of informed consent, or the end of the study, whichever occurs first.
