Trial summary

Patients with obstruction are associated with worse oncologic outcomes compared with those having nonobstructive tumors. Conventionally, patients with malignant large bowel obstruction receive emergency surgery, with morbidity rates of 30%-60% and mortality rates of 7-22%, and about two-thirds of such patients end up… Read more about this study

About this study

Official title: Camrelizumab Combined With Neoadjuvant Chemotherapy After Stent Placement Versus Surgery Alone for Left-Sided Obstructive Colonic Cancer

Patients with obstruction are associated with worse oncologic outcomes compared with those having nonobstructive tumors. Conventionally, patients with malignant large bowel obstruction receive emergency surgery, with morbidity rates of 30%-60% and mortality rates of 7-22%, and about two-thirds of such patients end up with a permanent stoma. Self-expanding metallic stents (SEMS) haven been used as a bridge to surgery (to relieve obstruction prior to elective surgery) in patients with potentially resectable colorectal cancer. Several clinical trials demonstrate that SEMS as a bridge to surgery may be superior to emergency surgery considering the short-term outcomes. SEMS is associated with lower morbidity and mortality rate, increased primary anastomosis rate, and decreased stoma creation rate. Although about half of patients can achieve primary anastomosis after stent placement, the primary anastomosis rate is still significantly lower compared with nonobstructing elective surgery. The interval between stent placement and surgery may be not long enough that bowel decompression is insufficient at the time of operation. Furthermore#the long-term oncologic results regarding SEMS as a bridge to surgery are still limited and contradictory. Sabbagh et al. suggest worse overall survival of patients with SEMS insertion compared with emergency surgery, the 5-year cancer-specific mortality was significantly higher in the SEMS group (48% vs 21%, respectively, P=0.02). One interpretation is that tumor cells may disseminate during the procedure of colonic stenting placement. Immunotherapy has proven to be highly effective as first-line treatment of metastatic colorectal cancer (CRC). And immunotherapy also has emerged as a neoadjuvant approach, possibly changing treatment strategy for both primary resectable and metastatic CRC. We hypothesis that, regardless of the MSI state, immunotherapy (Camrelizumab, an anti-PD-1 antibody) combined with chemotherapy after stenting may improve overall survival by eradicating micrometastasis. Moreover, immunotherapy (Camrelizumab, an anti-PD-1 antibody) combined with neoadjuvant chemotherapy prolongs the interval between stent placement and surgery, and the time for bowel decompression is more sufficient, which may increase the success rate of primary anastomosis and decrease risk of stoma formation, and furthermore, improve OS and PFS.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Immunotherapy (Camrelizumab)Drug

    Also called Chemotheray (CAPOX or mFOLFOX6)

    After clinical success of colonic stenting, regardless of the MSI state, patients will receive Immunotherapy (Camrelizumab 200mg) for 2 cycles compined with neoadjuvant chemotherapy with mFOLFOX6 regimen for 3 cycles or CapeOx regimen for 2 cycles. Patients will undergo surgery 2-3 weeks after the last cycle chemotherapy

Questions about this trial

What is this clinical trial studying?

A study testing Immunotherapy (Camrelizumab) in people with Colorectal Cancer and Neoadjuvant Chemotherapy, run by Beijing Chao Yang Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 21 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jia Gang Han, MD (+861085231604, hjg211@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological complete remission (time frame: 2 weeks after patients received radical operation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2023.
