ShanghaiAges 18–85 - NCT07284992RecruitingPhase 2
Comparing short vs long radiation with immunotherapy for rectal cancer
This trial tests whether a short course of radiation followed by an immunotherapy drug (PD-L1 inhibitor) plus chemotherapy works as well as or better than a longer radiation course for locally advanced rectal cancer. The goal is to shrink tumors before surgery.
Jinan, ShandongAges 18–80 - NCT07269249Recruiting
Dostarlimab before surgery for advanced rectal cancer
This study looks at how well the immunotherapy drug dostarlimab works before surgery in patients with a specific type of advanced rectal cancer that has DNA repair problems (called dMMR/MSI-H). The goal is to see if it is safe and effective in the real world.
NaplesAges 18 years+ - NCT06718543RecruitingPhase 2
Short-course radiation with AK112 for rectal cancer before surgery
This trial tests whether combining short-course radiation with an immune therapy drug (AK112) plus chemotherapy before surgery is better than radiation alone for locally advanced rectal cancer. It aims to shrink tumors and improve outcomes without needing stronger treatments later.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT07198165RecruitingPhase 2
Short radiation followed by chemo plus bevacizumab with or without immunotherapy for rectal cancer
This trial tests whether adding an immunotherapy drug (PD-1 inhibitor) to standard chemoradiation and targeted therapy improves outcomes for locally advanced rectal cancer. It is for patients who have not had prior treatment and do not have certain genetic markers (BRAF mutation or MSI-H).
ShanghaiAges 18–75 - 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 - 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 - NCT07143487Recruiting
Family communication after genetic testing for colon cancer
This trial studies how patients with newly diagnosed colon cancer share genetic test results with their family members. It aims to improve communication and support after learning about hereditary risk.
Anchorage, AlaskaAges 18 years+ - NCT07125729Recruiting
Early cancer detection test for colorectal cancer
This trial uses two blood tests (Signatera and Haystack) to look for tiny bits of cancer DNA after surgery, to find out if the cancer comes back as early as possible. People with stage II, III, or IV colorectal cancer who have had or will have surgery to remove their tumor may join.
Goodyear, ArizonaAges 18 years+ - 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+ - 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 - 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+ - NCT05870800RecruitingPhase 2
Study Immunotherapy and Chemotherapy Before Colon Surgery
This trial tests immunotherapy plus chemotherapy given before surgery for colon cancer that hasn’t spread. It aims to shrink or control the tumor and improve outcomes in people whose tumor has certain immune/biologic features.
Houston, TexasAges 18–80 - NCT06965166Recruiting
Better CT scans for staging rectal cancer
This study tests a new, more detailed type of CT scan (called photon-counting CT) to see if it can better show how far rectal cancer has grown or spread. If you are already getting standard scans to stage your cancer, this study adds an extra CT scan with contrast dye to get clearer pictures.
Rochester, MinnesotaAges 18–99 - 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 - NCT06949098RecruitingPhase 2
Local tumor removal plus chemo-radiation for early low rectal cancer
This trial tests whether removing just the tumor locally, followed by chemotherapy and radiation, is effective for early-stage (T1-2 N0) rectal cancers located low or very low in the rectum. It may help you keep your anal opening and avoid major surgery that requires a permanent colostomy bag.
Shijiazhuang, HebeiAges 18–75 - 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 - 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 - 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+ - 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.
