Hangzhou, ZhejiangAges 18–75 - NCT07150949RecruitingPhase 2
Comparing two radiation schedules with chemotherapy and immunotherapy for rectal cancer
This study tests two different radiation regimens (long-course vs. short-course) combined with chemotherapy (CAPOX), an immunotherapy drug (PD-1 antibody), and a COX-2 inhibitor for people with MSS locally advanced rectal cancer. The goal is to see which approach works better in shrinking the tumor before surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - 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 - 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 - NCT07040098RecruitingPhase 2
Optimizing immunotherapy with chemo-radiation for rectal cancer
This trial tests combining immunotherapy with standard chemotherapy and radiation before surgery for locally advanced rectal cancer. It aims to see if this approach can improve outcomes for patients whose tumors have certain genetic features (pMMR or MSS).
BeijingAges 18–75 - NCT07005570RecruitingPhase 2
Short radiation and chemo with or without immunotherapy for rectal cancer
This trial tests if adding an immunotherapy drug (PD-1 inhibitor) and a targeted therapy (bevacizumab) to short-course radiation followed by chemo can improve outcomes for patients with locally advanced rectal cancer that is pMMR/MSS. The goal is to shrink the tumor before surgery and possibly avoid the need for more extensive treatment.
Guangzhou, GuangdongAges 18–75 - NCT06958432RecruitingPhase 2/Phase 3
Shorter radiation before chemo and immunotherapy for rectal cancer
This trial tests a shorter course of radiation before chemotherapy and an immunotherapy drug to shrink mid-to-lower rectal cancer that has not spread. The goal is to improve treatment response and reduce side effects, potentially allowing for less invasive surgery.
Guangzhou, GuangdongAges 18–75 - 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 - NCT06904365Recruiting
Ovarian-sparing radiation for young women
This study tests a way to give radiation therapy that avoids the ovaries as much as possible, to help preserve fertility and hormone function in young women.
St Louis, MissouriAges 18–50 - 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 - 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+ - NCT06802172Recruiting
Timing meals during cancer treatment for Alaska Native patients
This study tests whether scheduling meals at specific times of day can improve how patients feel during cancer treatment. It is for Alaska Native or American Indian people with certain cancers (rectal, HER2+ or triple negative breast, or other solid tumors) who are receiving neoadjuvant (before surgery) or adjuvant (after surgery) therapy.
Anchorage, AlaskaAges 21 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+ - NCT06682793RecruitingPhase 1/Phase 2
Study of A2B395 therapy for solid tumors with EGFR and HLA loss
This trial tests a new cell therapy called A2B395 for cancers that have EGFR, a protein on the cell surface, and have lost a specific marker called HLA-A*02. The therapy uses specially engineered immune cells to target and kill these cancer cells. This may help patients with colorectal, lung, head and neck, breast, kidney, or other solid tumors that are no longer responding to standard treatments.
Gilbert, ArizonaAges 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 - NCT06563388RecruitingPhase 3
SABR for limited metastatic cancer (ID-COMET trial)
This study tests a precise radiation technique called SABR to treat cancer that has spread to a few spots. It aims to see if this approach can help control the cancer better than usual treatment, especially for lung, prostate, colorectal, or other solid tumors with limited spread.
Buffalo, New YorkAges 1 year+ - NCT05938322Recruiting
Ketogenic diet during pelvic cancer radiation treatment
This trial studies whether a very low-carbohydrate (ketogenic) diet can be followed safely while you receive neoadjuvant radiation for locally advanced rectal cancer. It may help researchers understand effects related to nutrition and treatment tolerance during radiation.
RomeAges 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+ - 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 - NCT06281405RecruitingPhase 2
CAPOX and immunotherapy with or without radiation for rectal cancer
This trial tests whether adding radiation therapy to a combination of chemotherapy (CAPOX) and an immunotherapy drug (PD-1 antibody) is more effective than the combination alone for people with locally advanced rectal cancer that is MSS (microsatellite stable) or pMMR. It aims to improve outcomes for patients with high-risk features.
