CAR T cell therapy for mesothelin-positive solid tumors
This trial tests a new type of immune cell therapy (CAR T-cells) designed to target cancer cells that have a protein called mesothelin but have lost a marker that lets them hide from the immune system. It's for people with advanced solid tumors who have already tried standard treatments.
Gilbert, ArizonaAges 18 years+ - NCT06123156RecruitingPhase 3
Early erectile rehabilitation after rectal cancer treatment
This trial tests if sildenafil (Viagra) given soon after surgery and radiation for rectal cancer can help preserve erectile function. It is for men with normal erectile function before treatment who have a regular partner.
AmiensAges 18–70 - NCT06126406RecruitingPhase 1
CEA-targeting CAR-T cell therapy for advanced solid tumors
This trial tests a new immune cell therapy (CAR-T) designed to attack cancer cells that make a protein called CEA. It may be an option for people with advanced colorectal, esophageal, gastric, or pancreatic cancer who have already tried at least two standard treatments.
Wuhu, AnhuiAges 18 years+ - NCT06162650RecruitingPhase 2
Pre-surgery chemo-radiation therapy for rectal cancer
This trial tests a combination of chemotherapy and radiation therapy before surgery for people with mid or low rectal cancer that hasn't spread. The goal is to see if this approach works better than current treatments.
TainanAges 20 years+ - NCT06209099Recruiting
Organ preservation first for low-risk rectal cancer
This trial tests a strategy to avoid surgery by using watchful waiting after initial treatment for early-stage rectal cancer. It may help patients keep their rectum and avoid a permanent colostomy.
Beijing, Haidian DistrictAges 18–85 - NCT06214988Recruiting
Temporary stoma or not for rectal cancer surgery
This trial tests whether a temporary stoma (a bag on the belly) can be safely avoided in some people having rectal cancer surgery. The goal is to see if it's okay to skip the stoma in those with a low risk of complications.
MalmöAges 18 years+ - NCT06229041RecruitingPhase 3
Chemo and radiation with or without immunotherapy for high-risk rectal cancer
This trial tests if adding immunotherapy to standard chemotherapy and radiation before surgery helps shrink high-risk rectal cancer and prevent it from coming back. You may be a good fit if you have a specific type of advanced rectal cancer that hasn't spread to other parts of your body.
BeijingAges 18–75 - NCT06239194RecruitingPhase 1/Phase 2
MdX2001 for advanced solid tumors
This trial tests a new drug, MDX2001, for people with advanced solid tumors that have spread. The study aims to find the best dose and see how well it works.
Denver, ColoradoAges 18 years+ - NCT06254521RecruitingPhase 2
Tislelizumab plus chemo before surgery for MSS rectal cancer
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+ - NCT06263088Recruiting
Equity in GI Cancer Care Study
This trial is looking for Black patients newly diagnosed with any stage of gastrointestinal cancer to help improve cancer care and make sure research includes everyone. By joining, you help doctors learn how to better support patients like you.
Cleveland, OhioAges 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+ - 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 - NCT06501053Recruiting
Contact X-ray therapy for early rectal cancer
This trial tests a special type of contact X-ray (brachytherapy) for early-stage rectal cancer. It may help avoid major surgery by treating the tumor from inside the rectum.
Stockholm, SolnaAges 18 years+ - NCT06536127Recruiting
Immune cells in non-spreading rectal cancer treatment
This study is looking at immune cells (NK cells and ImmunoScore) in the blood of people with rectal cancer that hasn't spread. It may help doctors learn more about how the immune system responds to standard chemoradiation treatment.
AvignonAges 18 years+ - NCT06546176Recruiting
Comparing two surgical methods for colorectal cancer
This trial tests two different ways to reconnect the intestine after removing a sigmoid or upper rectal tumor. The goal is to see which method leads to better healing.
CairoAges 18 years+ - NCT06565052Recruiting
Exercise and nutrition before rectal cancer surgery study
