Qingdao, ShandongAges 18–75 - NCT06940388RecruitingPhase 2
Immunotherapy plus standard treatment for rectal cancer
This trial is testing whether adding the immunotherapy drug tislelizumab to standard total neoadjuvant treatment (chemotherapy and radiation before surgery) can improve outcomes for people with locally advanced rectal cancer. The goal is to see if the combination helps shrink the tumor more than standard treatment alone.
MainzAges 18 years+ - NCT07194616Recruiting
Rectal cancer blood test study before surgery
This trial is studying a blood test (CTC) for people with rectal cancer that hasn't spread to other parts of the body. It aims to see how the test relates to treatment outcomes after surgery.
OlomoucAges 18 years+ - NCT07347951RecruitingPhase 2
New drug combo for rectal cancer patients who want to save their anus
This trial tests a combination of short-course radiation, chemotherapy, and two targeted drugs (Serplulimab and Bevacizumab) for people with a specific type of rectal cancer. It aims to see if this treatment can help shrink the tumor enough to avoid surgery and keep the anus.
Wenzhou, ZhejiangAges 18–75 - NCT07393048Recruiting
Personalized ctDNA test to predict rectal cancer treatment response
This trial uses a personalized blood test (ctDNA-MRD) to see how well neoadjuvant therapy works for rectal cancer. If you have stage II or III rectal cancer that can be surgically removed, this study might help guide your treatment.
Beijing, Beijing MunicipalityAges 18–75 - NCT06332274RecruitingPhase 3
Tislelizumab for cancer patients with minimal residual disease
This trial is for people who have completed standard cancer treatments (like surgery, chemo or radiation) and have no visible cancer on scans, but may still have very small amounts of cancer DNA in their blood. The study tests whether the drug tislelizumab can help prevent the cancer from coming back.
Villejuif, Val De MarneAges 18 years+ - NCT05378919RecruitingPhase 2
Testing new pre-surgery treatment for locally advanced rectal cancer
This Phase 2 trial compares a pre-surgery (neoadjuvant) treatment plan versus the standard plan for people with stage II–III rectal cancer. The goal is to see which approach works better and is safe before surgery.
KaunasAges 18 years+ - NCT04089631RecruitingPhase 3
Blood test guides extra treatment after stage II colon cancer surgery
This study uses a blood test called ctDNA to decide whether you need extra (adjuvant) chemotherapy after stage II colon or certain stage II rectal cancer surgery. It may help avoid unnecessary treatment or better target people who still have signs of cancer after surgery.
Dresden, SaxonyAges 18 years+ - 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 - NCT04245683Recruiting
Testing non-surgical treatment for newly diagnosed rectal cancer
This study looks at whether it’s practical and safe to treat certain rectal cancers without surgery. You may be offered non-surgical (“neoadjuvant”) treatment and close follow-up to see how well it works in a rural setting.
Cooperstown, New YorkAges 18 years+ - NCT05174169RecruitingPhase 2/Phase 3
Adjuvant colon chemotherapy guided by tumor DNA results
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
Birmingham, AlabamaAges 18 years+ - NCT05236972RecruitingPhase 3
PD-1 antibody after colon cancer surgery for dMMR stage III
This phase 3 trial studies a PD-1 antibody medicine given after surgery to help prevent stage III colon cancer from coming back. It is specifically for people whose tumor is mismatch repair–defective (dMMR) or MSI-H, which may make the cancer more responsive to immune-based treatment.
GuangzhouAges 18–75 - NCT06028724Recruiting
Looking for cancer mutations using a blood test
This study uses a blood test (liquid biopsy) to find genetic changes in advanced solid tumors. It may help doctors choose the right treatment and monitor how well it works over time.
Aviano, PordononeAges 18 years+ - NCT07605611Recruiting
Somatostatin and Diet vs. Stoma After Rectal Cancer Surgery
This trial tests whether using a medication called somatostatin plus a clear liquid diet can safely prevent serious complications after surgery to remove rectal cancer, without needing a temporary opening in the abdomen (stoma). You'll be randomly assigned to receive either somatostatin with diet changes or a stoma, depending on your individual risk factors.
Ezhou, HubeiAges 18–75 - NCT07227636RecruitingPhase 2
Immunotherapy for ctDNA-positive colorectal cancer after surgery
This trial tests two immunotherapy drugs, botensilimab and balstilimab, for people with colorectal cancer who have had surgery and chemotherapy but still have detectable cancer DNA in their blood. The goal is to see if these drugs can help clear the remaining cancer cells.
Basking Ridge, New JerseyAges 18 years+ - NCT02966483Recruiting
