Recruiting studies
- NCT03125343Recruiting
Watch-and-wait after rectal cancer treatment for select patients
This study looks at whether some people with rectal cancer can safely avoid immediate surgery after (chemo)radiation, instead closely monitoring their response. It may help some patients reduce treatment burden if the cancer fully responds.
GothenburgAges 18 years+ - NCT04808323RecruitingPhase 1
MRI-guided radiation to help preserve organs in rectal cancer
This Phase 1 study tests a radiation treatment approach guided by MRI scans to help keep nearby organs functioning while treating rectal cancer. It is designed to find a safe, effective way to target the tumor and adjust treatment during the course of therapy.
Milwaukee, WisconsinAges 18 years+ - NCT03179540Recruiting
Watch-and-wait treatment after rectal cancer radiation
This trial looks at a “non-surgery” approach for some people with locally advanced rectal cancer who respond very well to radiation plus chemotherapy. If your cancer shows a complete clinical response on follow-up checks, the study may help you avoid an immediate major operation while closely monitoring you.
Toronto, OntarioAges 18 years+ - NCT05970133Recruiting
Robotic surgery vs laparoscopy for left colon cancer
This trial compares two ways to remove left-sided colon cancer and take the specimen out through the anus (without a large external incision). It may help find which approach is safer and more effective for curing Stage I–III disease.
TaipeiAges 18 years+ - NCT06762405RecruitingPhase 3
Testing dostarlimab with short radiation for MSI rectal cancer
This trial tests a new approach: giving the immunotherapy drug dostarlimab along with a short course of radiation before surgery, with the goal of avoiding surgery in many patients. It is for people with a specific type of rectal cancer (MSI-H or dMMR) that has not spread to other organs.
DijonAges 18 years+ - NCT06157463Recruiting
FAPI imaging for newly diagnosed rectal cancer
This trial tests a new imaging agent called 68Ga-FAPI to see how well it finds rectal cancer and guides treatment. It's for people with new stage II or III rectal cancer who are about to start neoadjuvant therapy (treatment before surgery).
TaoyuanAges 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 - 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+ - 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 - NCT05254327RecruitingPhase 2
Radiation plus or minus BMX-001 for advanced rectal cancer
This Phase 2 study tests two different ways of giving radiation before surgery for locally advanced rectal cancer, with or without an added study drug called BMX-001. It aims to see whether the shorter/longer radiation plans and BMX-001 improve cancer control and are safe.
Lexington, KentuckyAges 18 years+ - NCT06628674Recruiting
Online videos for recovery after rectal cancer surgery
This trial tests if watching online interactive videos can help people who have had surgery for stage I to III rectal cancer deal with common bowel problems after treatment. Your participation could lead to better support tools for other patients.
Taoyuan, 中和區Ages 20 years+ - NCT06923345RecruitingPhase 2
Modified long-course radiation and chemo with immunotherapy for rectal cancer
This trial tests a treatment plan involving radiation, chemotherapy, and an immunotherapy drug (a PD-1 inhibitor) for people with a specific type of high-risk rectal cancer. The goal is to see if this combination helps shrink the tumor before surgery.
Guangzhou, GuangdongAges 18–75 - NCT02355379RecruitingPhase 3
Chemo after colon cancer surgery for adults 70 and older
This Phase 3 trial studies whether giving chemotherapy after surgery helps people age 70+ with stage III colon cancer. You would be compared to another planned treatment approach, aiming to lower the chance of the cancer coming back.
Fort de France, GuadeloupeAges 75 years+ - NCT07651553Recruiting
Transanal vs. Robotic Surgery for Rectal Cancer
This trial compares two surgical approaches to remove rectal cancer while preserving bowel function. Researchers want to see which method—performed through the anus or with robotic assistance—leads to better outcomes and quality of life.
Guangzhou, GuangdongAges 18–75 - NCT05789433Recruiting
Aerobic exercise study after colon or rectal cancer surgery
This trial studies whether a supervised aerobic exercise program helps muscles “remodel” (change/strengthen) after colon or rectal cancer treatment. It may help people improve physical function during recovery, but you can only join if it’s safe for you and you can follow the study plan.
Orlando, FloridaAges 18 years+ - NCT05663775RecruitingPhase 2
Mesalamine to prevent bowel inflammation after melanoma immunotherapy
This study tests whether taking mesalamine can prevent colitis (bowel inflammation) in people with advanced melanoma who are treated with ipilimumab plus nivolumab. It may help reduce dangerous stomach or bowel side effects from this cancer treatment.
Edmonton, AlbertaAges 18 years+ - NCT06843434RecruitingPhase 2
Study of two immunotherapy drugs for rectal cancer
This trial tests a combination of two immunotherapy drugs, botensilimab and balstilimab, for people with newly diagnosed rectal adenocarcinoma that has not spread. The goal is to see if this treatment can shrink the tumor before surgery.
Basking Ridge, New JerseyAges 18 years+ - NCT06997497RecruitingPhase 3
Study of Calderasib with other drugs for colorectal cancer
This trial tests a new drug called Calderasib combined with targeted therapy or chemotherapy for people with advanced colorectal cancer that has a specific genetic change (KRAS G12C mutation). It may be an option for those who have not had prior treatment for advanced disease.
Los Angeles, CaliforniaAges 18 years+ - NCT05059444Recruiting
Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.

Common questions
- Are there clinical trials for rectal cancer stage iii?
- Yes. Clin2 currently lists 92 recruiting rectal cancer stage iii studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a rectal cancer stage iii trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a rectal cancer stage iii trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
