CEA-targeted CAR-T therapy for advanced solid tumors
This trial tests a type of immunotherapy called CAR-T, which is designed to recognize and attack cancer cells that have a protein called CEA on their surface. It's for people with advanced cancers like colorectal, esophageal, gastric, pancreatic, lung, or bile duct cancer who have tried at least two standard treatments.
Hefei, AnhuiAges 18 years+ - NCT07162714RecruitingPhase 2
Short-course radiation plus AK112 for mismatch repair-proficient rectal cancer
This trial tests a new immunotherapy drug (AK112) given after a short course of radiation. It is for people with a specific type of mid-low rectal cancer that has not spread and has not been treated before.
Hangzhou, ZhejiangAges 18–75 - 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+ - NCT07113275RecruitingPhase 3
Short versus long radiation schedule for advanced rectal cancer
This study compares two different schedules of radiation (a short course versus a longer course) followed by standard chemotherapy and immunotherapy for advanced rectal cancer. It aims to see which approach works best to shrink the tumor before surgery.
Wuhan, HubeiAges 18–75 - 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+ - NCT07068763RecruitingPhase 2
Short radiation plus drugs for early rectal cancer
This trial tests a combination of short-course radiation, chemotherapy (capecitabine), and two immunotherapy drugs (PD-1 and CTLA-4 inhibitors) for people with early-stage rectal cancer who want to avoid surgery and keep their anus. The goal is to see if this treatment can shrink the tumor enough to avoid major surgery.
Hangzhou, ZhejiangAges 18–80 - NCT07056374Recruiting
New bowel connection method for colon or rectal cancer surgery
This trial tests a new way of connecting the bowel after removing cancer or precancerous lesions in the sigmoid colon or upper rectum. It is for patients who are having planned, curative surgery and may help reduce complications.
AmsterdamAges 18 years+ - NCT07011576RecruitingPhase 2
Fruquintinib plus FOLFIRI for second-line metastatic colorectal cancer
This trial tests a combination of two drugs, fruquintinib and FOLFIRI chemotherapy, as a second treatment option for people with metastatic colorectal cancer. It is designed for patients who have already received one prior treatment containing oxaliplatin, fluoropyrimidine, and bevacizumab.
Denver, ColoradoAges 18 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 - NCT06936774RecruitingPhase 3
Intensive follow-up after rectal cancer surgery to improve recovery
This study tests whether a more intensive follow-up program after rectal cancer surgery can improve your recovery, daily function, and overall quality of life. If you've had a temporary ileostomy and are waiting for reversal, this extra support may help you feel better faster.
BaselAges 18 years+ - NCT06883084Enrolling by invitation
How lymph node changes affect rectal cancer outcomes
This trial looks at how much the lymph nodes respond to chemoradiation before surgery in people with locally advanced rectal cancer. It aims to understand if that response can predict long-term results and guide future treatment choices.
Ages 18–65 - NCT06831981Recruiting
Heat therapy with chemo and radiation for rectal cancer
This trial tests if adding heat therapy (hyperthermia) to standard chemotherapy and radiation helps treat rectal cancer that has high-risk features. Heat therapy is thought to make cancer cells more sensitive to treatment.
Tübingen, Baden-WurttembergAges 18 years+ - NCT06824688Recruiting
Comparing robotic surgery types for rectal cancer
This trial compares two robotic surgery methods for rectal cancer: using one small incision (single-port) versus several small incisions (multi-port). The goal is to see which approach offers better outcomes while preserving the sphincter (the muscle that controls bowel movements).
ChongqingAges 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+ - 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+ - 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+ - NCT06719414Recruiting
Using a special MRI to predict rectal cancer response to pre-surgery therapy
This trial uses a special type of MRI scan (called amide proton transfer-weighted imaging) to look at your rectal cancer before and after chemotherapy and/or radiation. The goal is to see if the scan can predict whether the cancer has completely disappeared by the time of surgery, which could help guide future treatment decisions.
Guangzhou, GuangdongAges Any age - 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+ - NCT05576480RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for rectal cancer without mismatch repair
This Phase 2 study tests penpulimab (an immunotherapy medicine) given with CAPEOX chemotherapy before surgery for rectal cancer that is “MSS” (not the mismatch-repair type). It aims to shrink the tumor and improve outcomes by treating before the operation.
Shanghai, None SelectedAges 18–75 - 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.
