This trial tests a combination of an immunotherapy drug (tislelizumab) plus chemotherapy before surgery for people with a specific type of rectal cancer that has not spread to other organs. The goal is to see if this approach can shrink the tumor more effectively than standard treatment.
Nanning, GuangxiAges 18 years+ - NCT06287814Recruiting
Blood test to detect leftover cancer DNA in colorectal cancer patients
This study uses a simple blood test (liquid biopsy) to look for tiny bits of tumor DNA remaining after colorectal cancer surgery. It aims to see if the test can help predict whether the cancer will come back, especially in people with stage III cancer who will receive chemotherapy.
Montpellier, HéraultAges 18 years+ - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 18 years+ - NCT06565052Recruiting
Exercise and nutrition before rectal cancer surgery study
This trial tests whether a personalized exercise and nutrition program before rectal cancer surgery can help you recover faster and have fewer complications. If you are not very active right now, you may be able to join.
Boston, MassachusettsAges 18 years+ - NCT06589388Recruiting
Using a blood test to predict rectal cancer treatment success
This trial is looking at whether a simple blood test (ctDNA monitoring) can help predict how well total neoadjuvant therapy (chemo and radiation before surgery) works for rectal cancer. It may help doctors tailor treatment to your specific needs.
Ho Chi Minh CityAges 18–80 - NCT06613165Recruiting
Short vs long treatment for stage II-III rectal cancer with dMMR
This trial tests how long you need a PD-1 immunotherapy before surgery for a specific type of rectal cancer (dMMR/MSI-H). It looks at whether a shorter or longer course works best. This could mean fewer side effects and a quicker path to surgery.
Xi'an, ShaanxiAges 18–80 - NCT06746012Recruiting
Health app study for colorectal cancer survivors and their caregivers
This study tests a mobile health program to help colorectal cancer survivors and their family caregivers stick to healthy lifestyle habits. It's for survivors who are at least 6 months past treatment and have a smartphone.
Columbus, OhioAges 18 years+ - NCT06758830RecruitingPhase 2/Phase 3
Total neoadjuvant therapy vs surgery for rectal cancer
This trial tests whether a full course of chemotherapy and radiation before any surgery (called total neoadjuvant therapy) can help you avoid surgery and preserve your rectum. It is for people with a specific early stage of rectal cancer that has not spread.
VilniusAges 18 years+ - NCT06780787RecruitingPhase 2
Study of chemo plus immunotherapy for localized rectal cancer before surgery
This trial tests a combination of chemotherapy (FOLFOX) and two immunotherapies (botensilimab and balstilimab) before surgery for patients with localized rectal cancer. It aims to see if adding immunotherapy helps shrink the tumor and improve outcomes.
Duarte, CaliforniaAges 18 years+ - NCT06834126RecruitingPhase 1
Papaverine with radiation for advanced rectal cancer
This trial tests if adding papaverine (a drug) to radiation therapy can help people with locally advanced rectal cancer avoid surgery and keep their rectum. It is for patients who have already had chemotherapy and want a non-surgical approach.
Duarte, CaliforniaAges 18 years+ - NCT06850090RecruitingPhase 3
Comparing two chemo drugs before radiation for rectal cancer
This trial tests if a newer chemo pill (TAS-102) works better than the standard pill (capecitabine) when given before radiation and surgery for rectal cancer. It is for people with stage II or III rectal cancer that has certain high-risk features.
Jinan, ShandongAges 18–75 - NCT06968221RecruitingPhase 3
Bovine reinforcement for stomach, colorectal, and lung surgery
This trial tests whether a bovine reinforcement material helps make staple lines in stomach, colorectal, and lung surgeries stronger and safer. It may reduce the risk of leaks or bleeding at the staple line.
ShanghaiAges 18–75 - NCT07095439RecruitingPhase 2
Sandwich treatment for stage 2 and 3 rectal cancer
This trial tests a new way of giving radiation and chemotherapy before surgery for rectal cancer that hasn't spread. It aims to see if this 'sandwich' approach is safe and works better than standard treatment.
CairoAges 18–70 - NCT07108127RecruitingPhase 2
Targeted drugs plus chemo for HER2-positive rectal cancer
This trial tests whether a combination of two targeted drugs (trastuzumab and pertuzumab biosimilars) plus chemotherapy can shrink advanced HER2-positive rectal cancer before surgery. It aims to improve response and potentially reduce the need for more aggressive treatments.
BeijingAges 18 years+ - NCT07176182RecruitingPhase 2
Chemotherapy with alvenor for rectal cancer with high YWHAB
This trial tests adding the drug alvenor to standard chemotherapy before surgery for rectal cancer patients whose tumors have high levels of a protein called YWHAB. The goal is to see if this combination can improve treatment outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07352280Recruiting
Immunotherapy before surgery for certain colorectal cancers
This trial tests a new immunotherapy drug (tislelizumab) given before surgery for people with stage II or III colorectal cancer that has a specific DNA repair problem (dMMR/MSI-High). The drug aims to shrink the tumor and improve treatment outcomes.
Beijing, UndefinedAges 18 years+ - NCT02107105Recruiting
Study how surgery affects life quality in rectal cancer
This trial studies how surgical treatment for rectal cancer affects patients’ quality of life and other day-to-day impacts. It may help doctors understand what to expect after surgery and how to better support patients.
Houston, TexasAges 18 years+ - NCT03051464RecruitingPhase 2/Phase 3
Testing two ways to boost radiation to prevent rectal surgery
This study looks at whether two different added “boosts” of radiation can work as well for rectal cancer patients, aiming to avoid or reduce the need for rectal cancer surgery. You would receive a specific combination of radiation (including brachytherapy) and chemotherapy, and your tumor’s location and size will determine if you can take part.
Dallas, TexasAges 18–80 - NCT07405476RecruitingPhase 2
Zanidatamab before surgery for HER2 positive colon or rectal cancer
This trial tests if the drug zanidatamab, given before surgery, can help treat colon or rectal cancer that has a specific marker called HER2. The goal is to see if this approach can shrink tumors and improve outcomes for people whose cancer has not spread to other parts of the body.
Atlanta, GeorgiaAges 18 years+ - NCT07458529RecruitingPhase 2
Chemoradiation plus immunotherapy with or without probiotics for rectal cancer
This trial tests adding an immunotherapy drug (tislelizumab) and a probiotic to standard chemoradiation for locally advanced rectal cancer that has not spread. The goal is to see if the probiotic helps the treatment work better.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07346534Enrolling by invitation
Comparing reinforced vs. standard bowel connection in rectal cancer surgery
This study compares two ways of reconnecting the bowel after removing rectal cancer using keyhole surgery. It aims to see if a reinforced connection (with extra support) helps prevent leaks better than the standard method.
