BeijingAges 18–75 - NCT06864013RecruitingPhase 2
Short course radiation with chemo and immunotherapy for rectal cancer
This trial tests a combination of short course radiation therapy, chemotherapy, and two immunotherapy drugs for people with a specific type of rectal cancer that is locally advanced but can still be removed by surgery. It may offer a more effective treatment option for those with mismatch repair proficient (pMMR) or microsatellite stable (MSS) tumors.
Hangzhou, ZhejiangAges 18–75 - NCT06459869RecruitingPhase 1
NG-350A plus chemoradiotherapy for advanced rectal cancer
This trial is testing a new virus-based therapy (NG-350A) combined with standard chemoradiotherapy for people with locally advanced rectal cancer. It aims to see if the combination is safe and can help shrink tumors before surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT06802666RecruitingPhase 2
Short radiation plus combo drugs for rectal cancer
This trial tests a new combination for rectal cancer that hasn't spread far: a short course of radiation followed by two drugs (AK112 and CAPOX). The goal is to shrink the tumor before surgery and possibly avoid more aggressive treatments.
HubeiAges 18–75 - NCT06840665RecruitingPhase 2
Radiation plus immunotherapy and chemo for rectal cancer
This trial combines a special type of radiation (MRI-guided adaptive radiotherapy) with an immunotherapy drug (PD-1 antibody) and chemotherapy (CAPOX) for locally advanced rectal cancer. The goal is to see if this combination can improve treatment outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07527026RecruitingPhase 2
Camrelizumab and chemotherapy with radiation for advanced rectal cancer
This trial tests a combination of an immunotherapy drug (camrelizumab) with chemotherapy and radiation to shrink advanced rectal cancer before surgery. The goal is to help more patients have successful surgery with complete tumor removal.
Beijing, Beijing MunicipalityAges 18–75 - 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 - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT04527861Recruiting
Minimally invasive single-incision surgery for colon cancer
This trial compares a single-incision laparoscopic operation versus the usual laparoscopic operation for colorectal (colon or “high rectum”) cancer. It looks at cancer outcomes and may help determine which approach is safer and works better for the right patients.
Lanzhou, GansuAges 18–85 - NCT06052332Recruiting
Comparing two pre-surgery treatments for older adults with rectal cancer
This study compares two approaches to treating rectal cancer in people age 70 and older who have not yet had surgery. One approach gives chemotherapy and radiation before surgery, and the other adds more chemotherapy after radiation. The goal is to find which plan works better with fewer side effects.
Antwerp, AntwerpenAges 70 years+ - NCT06194708Recruiting
Why some temporary stomas are never reversed after rectal cancer surgery
This trial looks at why some people who had a temporary stoma (a bag for waste) after rectal cancer surgery never get it reversed. It collects information from medical records to find patterns that might explain this.
Beijing, Beijing MunicipalityAges 18–100 - NCT06204094RecruitingPhase 2
Preserving the anus with chemo, immunotherapy, and radiation for rectal cancer
This trial tests a treatment plan that combines chemotherapy, immunotherapy, and radiation before surgery for patients with middle or low rectal cancer. The goal is to shrink the tumor enough to avoid removing the anus, preserving bowel function.
Jinhua, ZhejiangAges 18–75 - NCT06647680RecruitingPhase 2
Chemo and immunotherapy before surgery for rectal cancer
This trial tests a combination of chemotherapy and an immunotherapy drug (a PD-1 inhibitor) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can improve outcomes compared to standard treatment.
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 - NCT07494201Recruiting
MIMICC study for people with colorectal cancer
This trial is studying patients with colorectal cancer who are scheduled for surgery. Researchers want to learn more about the cancer to improve future treatments.
