Recruiting studies
- NCT05563922RecruitingPhase 2
Testing a plan to preserve the anus after rectal chemo-radiation
This Phase 2 study tests a “total neoadjuvant” (chemo plus radiation before the main treatment) plan to see if some people with low rectal cancer can keep their anus. It may help you avoid permanent colostomy if your cancer responds well and you meet the study rules.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05772481Recruiting
PET-MRI scan test for rectal cancer after pre-surgery treatment
This study looks at whether a special scan called PET-MRI can better show how rectal cancer responds to treatment given before surgery. If it works well, it could help doctors plan the right next steps after chemoradiotherapy.
StrasbourgAges 18–75 - NCT06822634Recruiting
Advanced imaging for rectal cancer treatment response
This trial uses advanced MRI scans to see how well rectal cancer is responding to radiotherapy. It may help doctors better understand which treatments work best for patients with more advanced disease.
GlasgowAges 18 years+ - NCT07108348Recruiting
ADAR1 levels in rectal cancer
This study looks at a protein called ADAR1 in rectal cancer tissue. It aims to see how ADAR1 levels might be related to the cancer and help doctors understand the disease better.
Konya, MeramAges 18–90 - NCT07372300RecruitingPhase 3
Heat therapy plus standard care for advanced rectal cancer
This trial tests whether adding modulated electro-hyperthermia (a gentle heat treatment) to standard therapy (radiation and chemotherapy) before surgery helps control locally advanced rectal cancer. It is for people whose cancer has not spread to other parts of the body.
Chiayi City, Dalin TownshipAges 20 years+ - NCT07026422RecruitingPhase 2
Combination immunotherapy with chemoradiation for high-risk rectal cancer
This trial tests a combination of two immunotherapy drugs (iparomlimab and tuvonralimab) plus standard chemotherapy and radiation before surgery for people with a specific type of high-risk rectal cancer. The goal is to see if adding these drugs can improve treatment results.
Jinan, ShandongAges 18–75 - NCT06923345RecruitingPhase 2
Modified long-course radiation and chemo with immunotherapy for rectal cancer
This trial tests a treatment plan involving radiation, chemotherapy, and an immunotherapy drug (a PD-1 inhibitor) for people with a specific type of high-risk rectal cancer. The goal is to see if this combination helps shrink the tumor before surgery.
Guangzhou, GuangdongAges 18–75 - NCT06958419RecruitingPhase 2/Phase 3
Short radiation plus targeted drugs for advanced colon cancer
This trial tests a combination of short-course radiation, chemotherapy, targeted therapy (bevacizumab), and an immunotherapy drug (PD-1 inhibitor) for people with advanced colorectal cancer that has spread and is not curable with surgery. It aims to see if this approach can help shrink tumors and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06812728RecruitingPhase 2
Chemo and radiation before surgery for advanced rectal cancer
This trial tests giving a strong chemotherapy combination (FOLFIRINOX) followed by radiation before surgery for locally advanced rectal cancer. If you have stage 3 or high-risk stage 2 rectal cancer that has not spread, this approach may shrink the tumor and improve outcomes.
Shibīn al Kawm, MenoufiaAges 18–70 - NCT07433673RecruitingPhase 2
Gemcitabine, cisplatin, nab-paclitaxel, and cemiplimab for locally advanced bile duct cancer
This trial tests a combination of four drugs to see if they shrink locally advanced bile duct or gallbladder cancer that cannot be removed surgically. It is for people who have not had prior treatment for this cancer.
New York, New YorkAges 18 years+ - NCT07478731RecruitingPhase 2
Combination therapy for advanced rectal cancer before surgery
This trial tests a new drug called SHR-1701 combined with standard chemotherapy and radiation for people with locally advanced rectal cancer. The goal is to shrink the tumor before surgery, making it easier to remove completely.
Wuhan, HubeiAges 18–75 - NCT05585814RecruitingPhase 2
New chemo plus immunotherapy before rectal surgery
This trial tests a combination of chemo, a medicine that blocks blood vessel growth, and an immune checkpoint drug given before rectal cancer surgery. It’s for people with locally advanced rectal cancer without distant spread, to try to shrink the tumor and improve surgical results.
ShanghaiAges 18–75 - NCT04927897Recruiting
Testing where to aim extra rectal radiation before surgery
This trial tests the best place to target an “extra boost” of radiation inside the rectum for certain rectal cancer patients. It may help guide more precise treatment planning before they have total mesorectal excision (TME) surgery.
Maastricht, LimburgAges 18 years+ - NCT05496491Recruiting
Before-surgery radiation and chemo for rectal cancer
This study tests a specific “before surgery” treatment (radiation plus chemotherapy), followed by more chemotherapy to improve outcomes in people with certain types of rectal cancer. You might be considered if your cancer is locally advanced but not spread to distant organs.
LarissaAges 18–80 - NCT04006951Recruiting
Registry study for people with rectal cancer in Montpellier
This is a hospital-based study that builds a clinical and biological database for people treated for rectal cancer at the Montpellier Cancer Institute. It helps researchers organize health information to better understand rectal cancer and improve future care.
MontpellierAges 18 years+ - NCT06576986Recruiting
Can a supplement prevent mouth sores during chemo?
This trial tests whether a special supplement (synbiotic) can prevent mouth sores caused by chemotherapy in people with colorectal cancer. It's for those starting treatment who live in or near Belo Horizonte, Brazil.
Belo Horizonte, Minas GeraisAges 18 years+ - NCT07325721RecruitingPhase 2
Shorter radiation with a focused boost for high-risk prostate cancer
This trial tests a shorter course of radiation therapy with an extra 'boost' to the most aggressive part of the tumor, combined with hormone therapy, for men with high-risk or locally advanced prostate cancer that has not spread outside the pelvis.
Charleston, South CarolinaAges 18 years+ - NCT07750951RecruitingPhase 2
Combination therapy before surgery for advanced rectal cancer
This trial tests a combination of two immunotherapy drugs and chemotherapy given before surgery for a type of rectal cancer that has a specific genetic marker (MSI-H/dMMR). The goal is to shrink the tumor and improve the chances of successful surgery.
Xi'an, ShaanxiAges 18 years+ - NCT04936581Recruiting
Quality of life after rectal cancer surgery
This study looks at patient-reported outcomes—how you feel and function—after surgery for rectal cancer. It may help doctors better understand recovery and well-being after different surgical approaches and treatments.
MadridAges 18–100 - NCT06542588RecruitingPhase 2
Short radiation plus chemo and immunotherapy for rectal cancer
This trial tests a combination of short-course radiation, chemotherapy, and two types of immunotherapy (HLX07 and Serplulimab) before surgery for advanced rectal cancer. It aims to see if this approach helps shrink tumors and improve outcomes.
Wuhan, HubeiAges 18–75 - NCT05731726RecruitingPhase 2
New treatment before surgery for locally advanced rectal cancer
This trial tests whether giving serplulimab (an immune medicine) plus CAPEOX chemotherapy and celecoxib before surgery can shrink locally advanced rectal cancer and improve outcomes. It may help by increasing immune attack on the tumor while chemotherapy helps reduce the cancer before the operation.
Hangzhou, ZhejiangAges 18–75 - NCT02102477Recruiting
Surgery or radiation for prostate cancer in the pelvis
This trial compares surgery versus radiation for men with locally advanced prostate cancer that has not spread to distant sites. It aims to see which treatment works better and is easier to manage for people like you.
AalborgAges 18–75 - NCT07549399RecruitingPhase 3
Radiation, Chemotherapy, and Immunotherapy for Rectal Cancer
This trial tests a combination of radiation, chemotherapy, and immunotherapy drugs before surgery for people with locally advanced rectal cancer. The goal is to shrink the tumor and improve outcomes for patients with higher-risk disease.
Guangzhou, GuangdongAges 18–75 - NCT03001362Recruiting
Wait-and-see treatment for people with rectal cancer
This study tests a “wait-and-see” approach instead of immediate surgery for certain rectal cancers, aiming to avoid unnecessary operations. It may help people who are medically able to stay under close monitoring and only have surgery if needed.
