Recruiting studies
- NCT05321134Recruiting
Testing single-port robot surgery for colorectal conditions
This study checks how well a newer single-opening (single-port) robot works for colorectal surgery. It may help surgeons perform operations with the robotic system in carefully selected colorectal conditions.
Sacramento, CaliforniaAges 18 years+ - NCT05938322Recruiting
Ketogenic diet during pelvic cancer radiation treatment
This trial studies whether a very low-carbohydrate (ketogenic) diet can be followed safely while you receive neoadjuvant radiation for locally advanced rectal cancer. It may help researchers understand effects related to nutrition and treatment tolerance during radiation.
RomeAges 18–75 - NCT06252142Recruiting
Monitoring after rectal cancer treatment
This study looks at whether careful monitoring (watch and wait) is a good option for people with rectal cancer who have already had certain treatments. It aims to see if this approach can help avoid major surgery.
Mumbai, MaharashtraAges 18–90 - NCT07325721RecruitingPhase 2
Shorter radiation with a focused boost for high-risk prostate cancer
This trial tests a shorter course of radiation therapy with an extra 'boost' to the most aggressive part of the tumor, combined with hormone therapy, for men with high-risk or locally advanced prostate cancer that has not spread outside the pelvis.
Charleston, South CarolinaAges 18 years+ - NCT06885385RecruitingPhase 2
Study of JS207 with or without JS015 and chemo for colorectal cancer
This trial tests a new drug combination (JS207 with or without JS015) along with chemotherapy for people with advanced colorectal cancer that has not spread to other parts of the body. It aims to see if the treatment is safe and helps shrink tumors.
Beijing, Beijing MunicipalityAges 18–75 - NCT07223424RecruitingPhase 2
Patient preference study: shot vs infusion for immunotherapy
This study compares two ways to take immunotherapy drugs (nivolumab or pembrolizumab): as a shot under the skin (subcutaneous) versus an infusion into a vein (intravenous). It looks at which method patients prefer and is for people with certain advanced cancers where these drugs are already approved.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07558083RecruitingPhase 3
Tracking colorectal cancer response using blood tests
This study tests whether a simple blood test can track how well your colorectal cancer is responding to first-line chemotherapy. By monitoring cancer markers in your blood, doctors may be able to detect treatment changes earlier than traditional imaging.
Mechelen, AntwerpenAges 18 years+ - NCT07108348Recruiting
ADAR1 levels in rectal cancer
This study looks at a protein called ADAR1 in rectal cancer tissue. It aims to see how ADAR1 levels might be related to the cancer and help doctors understand the disease better.
Konya, MeramAges 18–90 - NCT07308990Recruiting
Comparing limited vs. full lymph node removal during prostate surgery
This trial compares two types of lymph node removal during prostate cancer surgery to see if removing fewer lymph nodes is just as effective. It is for men with prostate cancer that has not spread beyond the pelvis.
Lyasny, Minsk OblastAges 18 years+ - NCT05431530Recruiting
Quality of life after rectal surgery for advanced ovarian cancer
This trial studies how patients’ day-to-day quality of life changes after a specific type of rectal/low anterior resection during treatment for advanced ovarian cancer. It may help the medical team understand what symptoms and recovery needs to expect after surgery.
SeoulAges 18 years+ - NCT05571644RecruitingPhase 2
Study compares two pre-surgery treatments for locally advanced rectal cancer
This Phase 2 trial tests whether a newer combination chemotherapy plus an immunotherapy medicine (cadonilimab/AK104) works better than standard chemotherapy before surgery for locally advanced colorectal cancer. The goal is to shrink the tumor and improve how well treatment works after surgery.
Guangzhou, GuangdongAges 18–70 - NCT06014372RecruitingPhase 2
Envafolimab before surgery for advanced rectal cancer
This trial tests envalolimab (an immunotherapy) alone or with chemo (CAPEOX) before surgery for locally advanced rectal cancer. It aims to shrink the tumor and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06698757RecruitingPhase 2
Testing different cycles of sintilimab before surgery for colorectal cancer
This trial tests how many cycles of the immunotherapy drug sintilimab given before surgery help treat colorectal cancer that is mismatch repair deficient (dMMR) or microsatellite instability-high (MSI-H). It is for locally advanced cancer that has not spread to other parts of the body.
Zheng'zhou, HenanAges 18–75 - NCT06903858RecruitingPhase 2
Toripalimab plus celecoxib for dMMR/MSI-H colorectal cancer
This trial tests whether combining toripalimab (an immunotherapy) with celecoxib (an anti-inflammatory drug) can shrink locally advanced colorectal tumors that have specific genetic features (dMMR or MSI-H). It aims to help people who haven't had any prior treatment for their colorectal cancer.
Guangzhou, GuangdongAges 18 years+ - NCT07425054RecruitingPhase 2
Chemoradiation with or without immunotherapy for anal cancer
This trial tests whether adding an immunotherapy drug (retifanlimab) to standard chemoradiation improves outcomes for people with locally advanced anal cancer. The treatment is adjusted based on HPV DNA levels in your blood.
Cleveland, OhioAges 18 years+ - NCT06854679Recruiting
MRI-guided radiation for rectal cancer
This trial tests a new way of giving radiation therapy for rectal cancer, using MRI scans to aim the radiation more precisely. It's for people who need chemotherapy and radiation before surgery, and it aims to make treatment more effective while reducing side effects.
Sutton, SurreyAges 18 years+ - NCT06002789RecruitingPhase 2
PD-1 immunotherapy with or without chemo before surgery for colorectal cancer
This trial tests a medicine called PD-1 (a type of immunotherapy that helps your immune system fight cancer), sometimes with chemotherapy, before surgery for a certain type of colorectal cancer. It is for people whose tumors have a specific DNA repair problem (dMMR or MSI-H) and whose cancer has not spread to distant organs.
Guangzhou, GuangdongAges 18–80 - NCT06864338Recruiting
Pilot study for a new colorectal cancer screening test
This study tests a new stool-based test for detecting colorectal cancer and advanced polyps. It aims to see how well it works compared to a colonoscopy. The results may lead to a simpler screening option.
Morrisville, North CarolinaAges 18 years+ - NCT07106034RecruitingPhase 2
Testing a new combo therapy for advanced colorectal cancer
This trial tests a combination of two drugs (ONGERICIMAB and TORIPALIMAB) for people with a specific type of colorectal cancer that did not respond to first treatment. It aims to see if this new approach can help shrink or control the cancer.

Study registry for advanced endoscopy treatments
This study keeps a record of people who choose an advanced endoscopy procedure (like ESD, EMR, advanced polypectomy, POEM, or treatment for Zenker’s). It aims to learn about real-world outcomes and safety, which may help improve care for future patients.
Montreal, QuebecAges 18 years+ - NCT07429110Recruiting
ColoSeal device study for rectal cancer surgery patients
This study tests a device called ColoSeal that protects the connection made during rectal cancer surgery. It is for patients who are having surgery to remove the tumor and reattach the bowel, and who also need a temporary ostomy.
