Personalized chemo selection for advanced colorectal cancer
This trial tests whether a functional test on a tumor biopsy can help choose the best first chemotherapy regimen (FOLFOX or FOLFIRI) for people with metastatic colorectal cancer. It aims to improve outcomes by matching treatment to each person's unique tumor biology.
TrondheimAges 18 years+ - NCT06787183RecruitingPhase 2
Short-course radiation with chemoimmunotherapy for rectal cancer that has spread to the liver
This trial tests whether combining short-course radiation with a chemotherapy regimen (CAPOX) and an immunotherapy drug (QL1706) can help treat rectal cancer that has spread to the liver. It is designed for patients who have not had any prior cancer treatment.
Fuzhou, FujianAges 18–75 - 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+ - NCT06745895Recruiting
Colorectal cancer and hepatitis C education and screening study
This study helps people who go to certain clinics get screened for colorectal cancer and hepatitis C. It provides information and support to those who haven't had all their recommended screenings yet.
Tampa, FloridaAges 45–75 - NCT06637462Recruiting
Studying standard treatment response before rectal cancer surgery
This study looks at how rectal cancer responds to the usual chemotherapy and radiation given before surgery. It aims to learn if certain molecular features of your tumor can predict how well it responds to treatment.
Middletown, New JerseyAges 18 years+ - NCT06617858RecruitingPhase 2
AMB-05X for colorectal cancer with ctDNA after treatment
This trial tests a drug called AMB-05X for people with colorectal cancer who have completed all intended treatments and show no signs of cancer on scans, but still have cancer DNA (ctDNA) in their blood. The goal is to see if AMB-05X can eliminate this remaining cancer DNA and prevent the cancer from coming back.
Houston, TexasAges 18 years+ - NCT06529523RecruitingPhase 2
Testing tislelizumab for dMMR colorectal cancer
This trial tests the immunotherapy drug tislelizumab for people with a specific type of colorectal or rectal cancer called dMMR. It aims to see if this treatment can shrink tumors or improve outcomes in patients who haven't had many other treatments.
New York, New YorkAges 18 years+ - NCT06449989Recruiting
Comparing genetics of colorectal cancer and its brain spread
This study compares the genetics of the original colorectal cancer with the cancer that has spread to the brain. It aims to understand how the tumor changes when it metastasizes, which may help guide future treatments.
Moscow, MoscowAges 18 years+ - NCT06424522Recruiting
Enema program for bowel problems after rectal cancer surgery
This trial tests a special enema program to help people with ongoing bowel problems (called LARS) after rectal cancer surgery. If standard treatments haven't worked, this program might offer a new way to manage symptoms like urgency and leakage.
Columbus, OhioAges 18 years+ - NCT06369259RecruitingPhase 2
Combination treatment for advanced colorectal cancer that resisted standard therapy
This clinical trial tests a new combination of three drugs for people with advanced colorectal cancer that has not responded to standard anti-EGFR treatments. The goal is to see if this combination can shrink tumors or slow the cancer down.
Houston, TexasAges 18 years+ - NCT06366841Recruiting
Stigma and mental health in rectal and anal cancer patients
This study looks at how stigma (feeling judged or embarrassed) and mental health affect people with rectal or anal cancer who are getting long-course radiation. By answering questionnaires, you can help researchers understand these challenges and find better ways to support patients.
RomaAges 18–75 - NCT06349642Recruiting
Testing a live tumor test for immune therapy response
This trial uses a special test on live tumor samples to see if it can predict how well immune checkpoint inhibitors (a type of immunotherapy) will work for different cancers. It may help doctors choose the best treatment for you.
Phoenix, ArizonaAges 18 years+ - NCT06328361Recruiting
Avoiding surgery for rectal cancer after good response to treatment
This trial tests a new approach: after initial treatment (like chemo or radiation), people with rectal cancer who have a complete response may be able to avoid surgery. Instead, they are monitored closely to see if the cancer stays away.
TallinnAges 18 years+ - NCT06287723Recruiting
Blood test for cancer DNA after liver surgery in colorectal cancer
This study uses a simple blood test (liquid biopsy) to look for tiny bits of cancer DNA after surgery for colorectal cancer that spread to the liver. It aims to see if this test can find cancer earlier than standard scans, which may help guide future treatment decisions.
MontpellierAges 18 years+ - NCT06225011RecruitingPhase 1
Can a common antidepressant help your immune system fight colorectal cancer before surgery?
This trial is testing whether a common antidepressant called fluoxetine (Prozac) can help your immune system fight colorectal cancer before surgery. It's for people with early-stage colorectal cancer who have not yet had treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06205485RecruitingPhase 3
Chemotherapy and surgery vs chemoradiation for rectal cancer
This trial compares two approaches for early-stage rectal cancer: chemotherapy plus local surgery versus standard chemoradiotherapy. It aims to see if less intensive treatment can work just as well, reducing side effects.
