NCT ID: NCT05732493 Not yet recruiting - Clinical trials for Locally Advanced Colon Cancer

Short-course Radiotherapy Combined With Chemotherapy and Pd-1 Inhibitor for Locally Advanced Colon Cancer(TORCH-C)

TORCH-C
Start date: March 1, 2023
Phase: Phase 2
Study type: Interventional

The study evaluates the combination of immunotherapy of PD-1 antibody and chemotherapy and neoadjuvant short-course radiotherapy in locally advanced colon cancer (LACC). Patients are randomly assigned into two prospective groups: treatment group and observerment group. In treatment group, a total of 60 patients will receive 5*5Gy short-course radiotherapy, followed by 4 cycles of capecitabine plus oxaliplatin (CAPOX) chemotherapy and PD-1 antibody, finally receive the surgery. In observerment group: a total of 60 patients will receive 4 cycles of CAPOX chemotherapy, then receive the surgery. The rate of pathologic complete response (pCR), long-term prognosis and adverse effects will be analyzed.

NCT ID: NCT04389151 Recruiting - Clinical trials for Locally Advanced Colon Cancer

Triplezumab Combined With CAPEOX Regimen in Neoadjuvant Therapy for Locally Advanced Colon Cancer

Start date: March 4, 2020
Phase: Phase 2
Study type: Interventional

According to the 2019NCCN guidelines, immunocheckpoint inhibitors are recommended for first-line treatment of metastatic colon cancer patients with high microsatellite instability (msi-h) or mismatched gene deletion (dMMR) who are not suitable for intensive treatment, and for all patients with second-line or above msi-h /dMMR treatment.This study is a single-center, single-arm phase II study of the use of triplezumab (JS001) combined with CAPEOX regimen in the neoadjuvant therapy of msi-h /dMMR for locally advanced colon cancer. The subjects received neoadjuvant therapy with triplezumab (JS001) combined with CAPEOX regimen, with one treatment cycle every 3 weeks and two cycles of surgery followed by pathological evaluation.

Perioperative Versus Postoperative CapOX Chemotherapy for Locally Advanced Colon Cancer

Start date: May 2017
Phase: Phase 3
Study type: Interventional

Adjuvant chemotherapy has been widely adopted worldwide for locally advanced colon cancer. However, more and more studies have found better efficacy and potential advantages of perioperative or neoadjuvant chemotherapy. The sooner the systemic chemotherapy is received, the better suppression it has on activity of tumor growth factors. Pre-operative chemotherapy may eliminate tiny metastases. It may also shrink the invasion of tumor before surgery, and thus reducing operational trauma and expediting recovery. With advances in radiology and tomography, staging before surgery is accurate enough to identify risks and prognosis for patients. The phase II trial conducted by our department has yielded encouraging results (N=47, CapeOX regimen, clinicaltrials.gov NCT02415829): after the neoadjuvant chemotherapy, no subject had disease progression, 68.1% subjects reached complete or partial response. Besides, the toxicity of neoadjuvant CapeOX chemotherapy was acceptable. The present randomized controlled phase III trial will be conducted to further compare efficacy and safety of the neoadjuvant and adjuvant CapeOX chemotherapy for patients with locally advanced resectable colon cancer in China. This study may have two periods, each will last for approximately 5 years. After the first period (n=994), if the results of the test group are better than the control group, the study will be terminated. Otherwise, the study will enter into period 2 (n=376) through selecting out genetically sensitive subjects and repeating the same trial process as period 1.
