Guangzhou, GuangdongAges 18–80 - NCT06312982RecruitingPhase 2/Phase 3
Chemo, radiation, and immunotherapy before rectal cancer surgery
This trial tests whether a combination of chemotherapy, radiation, and an immunotherapy drug (tislelizumab) before surgery can improve outcomes for people with locally advanced rectal cancer that has specific protein/gene markers (pMMR or MSS). It’s designed for those who have not yet had any treatment for their cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT05752136RecruitingPhase 3
Pre-surgery radiation plus immunotherapy and chemo for rectal cancer
This trial tests whether a short course of radiation before surgery, combined with the immunotherapy drug envafolimab and the chemo regimen CAPEOX, works better for shrinking locally advanced rectal cancer. It is aimed at people whose tumor is not “MMR-deficient” (it is pMMR/MSS), and it asks participants to be able to return for repeated checkups and treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT07026422RecruitingPhase 2
Combination immunotherapy with chemoradiation for high-risk rectal cancer
This trial tests a combination of two immunotherapy drugs (iparomlimab and tuvonralimab) plus standard chemotherapy and radiation before surgery for people with a specific type of high-risk rectal cancer. The goal is to see if adding these drugs can improve treatment results.
Jinan, ShandongAges 18–75 - NCT07462143RecruitingPhase 2/Phase 3
New drug plus chemo for advanced colorectal cancer
This trial tests a new drug (RC148) combined with standard chemotherapy as a first treatment for colorectal cancer that has spread or cannot be removed. The goal is to see if this combination works better than chemotherapy alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT06812728RecruitingPhase 2
Chemo and radiation before surgery for advanced rectal cancer
This trial tests giving a strong chemotherapy combination (FOLFIRINOX) followed by radiation before surgery for locally advanced rectal cancer. If you have stage 3 or high-risk stage 2 rectal cancer that has not spread, this approach may shrink the tumor and improve outcomes.
Shibīn al Kawm, MenoufiaAges 18–70 - NCT07555210Recruiting

This study tracks how a type of cancer treatment called anti-PD-1 immunotherapy affects bone strength over time. Researchers want to understand whether this treatment causes bone density loss and help develop ways to protect bones during cancer care.
Nashville, TennesseeAges 18 years+ - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT07369531Recruiting
Stoma-free survival after new anal-sparing surgery for low rectal cancer
This study compares a two-stage surgical technique (Turnbull-Cutait pull-through) to standard surgery for people with low rectal cancer. The goal is to see which approach helps more patients avoid a permanent stoma (bag) after surgery.
Changchun, JilinAges 18–75 - NCT04936581Recruiting
Quality of life after rectal cancer surgery
This study looks at patient-reported outcomes—how you feel and function—after surgery for rectal cancer. It may help doctors better understand recovery and well-being after different surgical approaches and treatments.
MadridAges 18–100 - NCT07802002Recruiting
Dietary supplement to prevent bowel injury during radiation for rectal cancer
This trial tests whether a special dietary supplement can help protect the rectum from radiation damage during chemoradiation for locally advanced rectal cancer. If it works, it may reduce painful bowel symptoms like frequent stools and cramping.
Guangzhou, GuangdongAges 18–75 - NCT07750951RecruitingPhase 2
Combination therapy before surgery for advanced rectal cancer
This trial tests a combination of two immunotherapy drugs and chemotherapy given before surgery for a type of rectal cancer that has a specific genetic marker (MSI-H/dMMR). The goal is to shrink the tumor and improve the chances of successful surgery.
Xi'an, ShaanxiAges 18 years+ - NCT03874026RecruitingPhase 2
Folfiri plus cetuximab for advanced, gene-matched colon cancer
This trial tests whether a combination chemotherapy (Folfiri) plus cetuximab works better for people with stage IV colorectal cancer that has specific tumor gene markers and a specific blood-gene type. It may help you shrink tumors or control the cancer if you match the study’s required lab and health criteria.
NaplesAges 18–75 - NCT05673148RecruitingPhase 2
Adding targeted tumor treatment to standard therapy for limited metastatic colorectal cancer
This trial tests whether adding a precise, targeted treatment to destroy remaining cancer spots (called total ablative therapy) after initial chemotherapy can improve outcomes for people with limited metastatic colorectal cancer. It aims to see if this extra treatment is safe and effective.
Kingman, ArizonaAges 18 years+ - NCT07450612Recruiting
Blood test and AI for early colorectal cancer detection
This study uses a simple blood test (liquid biopsy) and computer analysis to find early signs of colorectal cancer, precancerous growths, and Lynch syndrome. It aims to improve early detection and monitor for any remaining cancer after treatment.
Milan, LombardyAges 18 years+ - NCT05933122Recruiting
Sexual health support after rectal cancer surgery
This study looks at how common sexual difficulties are in women after rectal cancer surgery, and whether a sexologist-led support program can help. If you qualify, you may be asked about sexual well-being and take part in counseling support.
Brive-la-GaillardeAges 18 years+ - NCT07058012RecruitingPhase 2
Testing immunotherapy for ctDNA-positive colorectal cancer after treatment
This trial is for people with colorectal cancer whose ctDNA blood test is still positive after surgery and chemotherapy. It tests two immunotherapy drugs (cemiplimab alone or with fianlimab) to see if they can eliminate the remaining cancer cells and prevent the cancer from coming back.
Gainesville, FloridaAges 18 years+ - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.
Wuhan, HubeiAges 18–70 - NCT06633133Recruiting
Virtual ileostomy vs. diverting ileostomy for rectal cancer surgery
This trial compares a virtual ileostomy (a system that monitors leaks without creating a temporary opening) to a traditional diverting ileostomy (a temporary bag) in people having rectal cancer surgery. The goal is to see if the virtual method is safer and avoids a second surgery.
ChongqingAges 18 years+ - NCT07674732RecruitingPhase 2
Shorter radiation with immunotherapy for rectal cancer
This trial tests a shorter course of radiation followed by a combination of chemotherapy, immunotherapy, and a targeted drug (bevacizumab) for locally advanced rectal cancer that is mismatch repair proficient (pMMR) or microsatellite stable (MSS). The goal is to see if this approach can shrink the tumor enough for surgery while avoiding more extensive radiation.
Guangzhou, GuangdongAges 18–75 - NCT07646639RecruitingPhase 2
Radiation, chemotherapy, and immunotherapy for advanced rectal cancer
This study tests a combination of radiation therapy, chemotherapy drugs (capecitabine and oxaliplatin), and two types of immunotherapy (a PD-1 blocker and IL-2) for locally advanced rectal cancer. The goal is to see if this combination helps shrink tumors and improve outcomes before surgery.
Nanjing, JiangsuAges 18–70 - NCT07651553Recruiting
